The first step: the first LED guardrail lamp mounted to the wall: holes in the wall, installed expansion screws, and then install LED guardrail lamp, guardrail lamp with tapping screws; the distance between depending on customer requirements; generally is 1CM to 3CM.

The second step: then the signal line and LED guardrail lamp power line are jointed together, the signal line is generally four or five conductors have male and female plug two core; power line is two core of male and female plug;

The third step: install the power (transformers or switch power supply);According to the power of the transformer and guardrail lamps power to calculate how many a guardrail lamp can load each transformer; for example, LED colorful guardrail lamp with 108 LED lamp is 10W/M; LED guardrail lamp 144 lamp is 12W/M; if the aterproof transformer 400W, it can take 108pcs 36M lamp tube; 144 lamp with 32 M pipe. If the transformer can take 36M tube; put the transformer into 18 and 19 intermediate; connected with two lines, each side with 18.

Note: 1 the transformer is generally only used to power 80% to 90%;2 whether the power transformer is strong, each side connection pipe is best not more than 25M; because the power supply wire has the power loss; The LED guardrail lamp far from power supply the brightness is low;
The fourth step: LED guardrail lamp controller installation;
First install the sub controller, the controller is connected to the LED guardrail lamp directly; the in generally the sub controller gave three out ends of line , one end of a general power line is connected to 24V or 12V, pay attention to the sub controller can but supply to the power supply line.the power supply line can but the sub controller, other power supply has to be additionally connected guardrail tube, and the other two signal line is: a signal line is connected to the input of main controller; other signal line is output signal of guardrail tube。 the sub controller which connected with the branch control mark!Signal connect signal (five cores of male and female inserted), power supply is connected with a power supply (two cores of male and female inserted); then the main controller and sub controller connect together, if the control and main control distance will be far(pls adopt super five net lines), so that the signal is best; with a fixed number of LED digital tube, in general can be load to 100M; outline profile building body, each sub control with a channel; the specific situation according to LED renderings to install(manufacturers will help you calculate how much the sub control is require, the general will have installation drawings). NOTE:cut the digital tub line of different loop

The fifth step: electricity, communication

The transformer connect to a main power supply of 110V, and then using an air switch and a time switch; Control LED digital tube (LED guardrail lamp) unified electricity; and then the main control plug device inserted in the 110V power supply. The LED internal (monochrome & permanence lighting) guardrail tube installation:Monochrome guardrail tube connect to power supply with the electric line directly, internal control guardrail lamp installation, directly connected to the corresponding power line; here also mentioned that the internal control number LED guardrail lamp installation: internal number of guardrail lamp must be installed according to the order of a pipe installation; if not by the installation sequence will end up the whole synchronization. Internal control and internal control number guardrail tube must be energized simultaneously, to ensure the effect of synchronous change! Must be connected transformers or switch power supply with low voltage switching power supply, transformer or installed in the intermediate guardrail tube, will the effect of such a guardrail tube is more uniform!

Light wavelength table and application of light wavelength

Usually Red light is used as a night vision. The red light will not cause your pupil contraction, and lighting extinguished, your eyes do not need to re adapt to the dark. Red is usually in monochrome print processing is used as a “safe” color, because it will not damage of printing negatives。 yellow light has some advantages of red light and white light. Yellow light another advantage is that when you are reading less,because of long time reading cause eye fatigue Under blinding and reflection light。Green light can also be used as a night vision; the green light is especially suitable for reading a map or chart during the night. It is not so easy to be found by night vision equipment, are vulnerable to human discovery, bright green light lower than red.Blue light can be used to map reading; it is often favored by military personnel in the night, because blue light increased the contrast level. It can also be used as background work lights theatre and the performances of the color ighting.Blue&green light have similar advantages with green light at night vision, but with the color characteristics of blue-green light increases, some users like blue&green light for this reason.Red is used together with infrared night vision equipment. Otherwise, the human eye is invisible to infrared led light.Ultraviolet light is usually used as identification whether the banknote forgery, some UV light emitting diode lighting is popular in nightclubs and parties, they are used to make fluorescent material emits more light.The color of the light and light wavelength whether we can see The color of the light is determined by its wavelength, the units of light wavelength is nano ,also said to be 1/1000000000 meters.

Infrared detection

The basic method of infrared detection is divided into two types: passive and active. Passive infrared detection equipment in the application more; active infrared detection can be divided into single and double-sided method, in infrared detection method of heating method measured target is divided into steady and unsteady heating heating.Infrared detection instrument installation and delivery modes: fixed, portable, vehicle mounted and airborne type (helicopter loading) etc..
(1) the passive infrared detection means the measured target don’t hot up when check of infrared detection, using only measured target temperature to draw infrared detection on process of heat exchange between the measured target and environment。passive infrared detection used in the operation of device,components and scientific experiment。It no additional heat source,the basic all adoption with this way。
(2) active infrared detection of active infrared detection is the infrared detection before measured object active heating, heating source from the measured target. Way of make heat divided into a steady and non steady。infrared detection according to the different situation can be carried out in the heating process,also can be in stop heating for a certain period of time after continue their detection.

Method:
(1) one side detection:
sameMeasured Target make heating and infrared detection On same side.
(2) double-side method:
relative to the single single-sided method(the above method), double method is put on the heating measured target and infrared detection respectively in the target the positive and the negative two aspects.
(3) heating method:
1) steady state heating: steady heating mode will be measured target is heated to its internal temperature.the temperature will be reaches the homogeneous steady state, then it is placed in a lower (or higher) infrared detection of the constant temperature environment to check. This approach used for quality testing of materials, such as the analyte internal cracks, holes or debonding defects, then the measured object and environment of heat exchange in heat flow will be affected by the defects of obstacles, the corresponding outer surface can produce the change of temperature, compared with no surface defects will appear difference.
2) unsteady heating: heating of the measured target, do not need to make the internal temperature reaches the uniform or stable state.
3) as the heat into the measured object being tested evenly, heat flow into the inner speed should be decided by its internal conditions, if the internal defects, will become a baffle heat resistance, after a certain time will generate heat accumulation, will produce heat. Heat flux varies depending on the position of the defect caused by defects, direction, geometric dimensions and material thermal physical properties.

The application of LED to car industry(2)

For the development of LED lamp market for automobiles, some high-grade cars in America and Japan, Europe has begun t use of LED lighting, with the development of China’s economy, the automobile and motorcycle industry in recent years fast forward, its supporting products automobile and motorcycle lamp lights the demand quantity will be increased synchronously. Although a few years ago, LED lamp market expansion is slow, is expected to have a rapid development in the last two years, and has 2 lamp in the front combination lamps, (such as rear brake lamp and rear steering lamp) using LED light source. LED is called the fourth generation car light, LED lights in addition to higher one-time investment, compared with traditional incandescent lamps, LED has good quality and higher grade. As oil prices rise, the new energy vehicle development has attracted much attention, so energy saving is the main topic of widespread concern. LED highlights the enormous advantage in energy saving, believe that often focus on Audi’s new models may know, over the past few years continuously in the brake light on the popularity of the use of LED (light emitting diode: is composed of the electric energy can be directly converted into light energy made of crystal semiconductor compounds arsenic gallium and gallium phosphide is the basic material.) Appear in the headlight, compared with traditional incandescent lamps, LED made the headlights not only lighting effect is high, and low energy consumption. At the same brightness and high power light emitting diode when the demand for electricity is the halogen headlamps half. Although in the present circumstances, LED has not yet reached the level of energy-saving xenon headlamps, but this technique still has great development potential. Car lamp with LED lamp decoration and function is divided into two categories glorified car inside and outside with Decorative lamp, at present more than matched control circuit to realize the colorful transform. The most suitable function LED lamp indicating lamp backlight in the digital meter assembly display, before and after the turn lights brake indicator lamp, reversing lamp fog lamp profile indicating light reading lamp. The use of LED basic requirements and general use of the LED is similar, but the angle of the LED, color, brightness, voltage discrete value, depreciation, heat, ultraviolet proof and high reliability requirements to. In fact LED headlight technology has not only plays the role of decoration, a so-called “vase”, LED will rely on it

The application of LED to car industry

LED lamp refers to the use of LED (light emitting diode) as light source lamp. Because LED has the advantages of high brightness, color rich variety, low power consumption, long service life, LED has been widely used in the automotive field. LED lamp profile LED lamp production requirements LED lights will become the future market mainstream characteristic of vehicle lighting LED lamp development and classification of domestic LED lights the bottleneck of the development of domestic LED lamp prospect Brief
introduction of LED lamp
Now the car lights had incandescent lamp, halogen lamp, xenon lamp etc.. In addition to headlamps, other lamps such as lights, litter lights, car lights is the use of incandescent lamp etc.. But in recent years also popular at LED as indicating lamp, such as brake indicator light, turning indication lamp etc. Why the instead of incandescent lamps with LED? The outer cover can be made with the PC pipe, maximal temperature up to 135 degrees. Greatly improve the light transmission effect, enhance the impact resistance!! Resistance to weak acid and neutral oil. Effective period of 20 years. The original advantages of LED are significant compared with incandescent lamps,
First is the long life, generally up to tens of thousands hours, even one hundred thousand hours. Some people think that if the car lighting the use of LED in future, the whole car use period without changing the lamp.
Secondly is very energy-efficient, more than half of the same brightness of the incandescent lamp energy saving at least.
Thirdly is the high quality light, basically no radiation, which belongs to the “green light”. Fourthly is a LED has the advantages of simple structure, the internal support structure, seal around with epoxy resin transparent, good seismic performance.
Fifthly is not need hot start time, lighting fast response (nanosecond), suitable for fast moving objects using.
Sixth is applicable at a voltage of 6-12 volts, can be applied in automobile.
Seventh is the LED occupancy volume is small, the designer can transform lighting mode freely, auto modeling diversification. Automobile manufacturers favor LED, is completely determined by the advantages of the LED. This is LED lamp production requirementsFirst according to the standard optical design need of light shape requirements, including the LED brightness, distribution of light beam, design of beam angle。 Although LED can save energy and has the advantages of small size, but the beam angle of narrow and LED heat treatment is higher requirements, so LED is used as the lamp on the processing of the need to pay particular attention to the uniform light. Another is heat treatment for LED, if the heat do not, will not only affect the life of LED, but also lead to LED appears in the light emitting device attenuation, based on two restrictions, LED lamp has not been very good development, only a few top grade car assembly. Secondly LED quality control and check of light production coordination, it is relatively simple when compared to the headlights, lights require. But the main thing is to solve the problem of uniform light LED, namely, how to make uniform distribution when output of the LED light, and good heat dissipation problem solving of LED. LED lamp is dong after need to do some performance testing and 3C certification,LED lamp will become the market mainstream of vehicle lighting in future.
With the continuous development and evolution of LED technology, its applications in the automotive industry have been more widespread. However, the current LED companies in the lights, backlight, lighting and other three major application market is still in the development stage, certification, lean on demand that this year industrial growth contribution is not big, but along with the industrialization speed, the next LED companies in the lights, backlight, lighting and other three areas have a large number of applications.

The difference between downlights and spotlights

The difference between downlights and spotlights.

Many people are confused for led of Downlights and spotlights,
what distinction between the downlights and spotlights? What position should be applied to Home Furnishing ?and what is different effect of applying? We will talk about the downlights and spotlights Base on the questions above。Simply to think, the downlights led lamp is lighting a lamp compared to ordinary bright outfit is more focused,  usually used for general lighting or auxiliary lighting.spotlights lamp is lighting a highly condensing, which light is to specify a specific target. And it is mainly used for special lighting, such as emphasis a new place on a very good taste.

We will be talk about the distinguish downlights and spotlights from the several aspects.

1, from the source to see downlight can be replace the incandescent bulbs, and can also be replace energy-saving lamp. Incandescent lamp is a yellow light. Installed energy-saving lamps as lighting types (can be white or yellow light). The direction of the ceiling downlights light source is not adjustable. Common household lamp is used in quartz bulb, or lamp. Of course, large lamp is not necessarily used quartz bulb. Quartz bulb only yellow light. But the direction of the light source lamp can be freely adjusted general.

2, from the application location: downlight are generally installed in the ceiling, the general ceiling needs above 150mm can be installed. Of course, there are also external type lamp. downlight region is a very good choice In the absence of dome light or pendant mounted, respect to soft compare with the spotlights light lamp. In generally spotlights lamp can be divided into orbit, hanging type and embedded type etc.The spotlights Lamp with transformer, but also has without transformer. The embedded lamp can be installed in the ceiling. Tht spotlights Lamp is mainly used for the need to emphasize or performance, such as TV wall, paintings, jewelry and so on, can be made to enhance the effect of light.

3, from the price: point of view the same grade, The spotlights lamp is expensive compare with downlight lamp.It must be noted that, lamp generally cannot be used for lighting wool fabrics, nor near flammable obstacles, otherwise easy to cause fire. Although the spotlight more power but at a proper position has its decorative effect is not the same. The colorful lamp and lamp cup decorated, have a distinctive style.

LED solution —- LED heat dissipation

LED solution LED heat dissipation— aluminum substrate design choice of LED circuit design, in order to better solve the problem of heat dissipation, LED and some high power IC needs to use the aluminum base circuit board.Aluminum substrate is composed of PCB circuit layer (Tong Boceng), heat insulating layer and the metal base layer. Circuit layer requirements with current carrying capacity greatly, thus should use thick copper foil, thickness of 35 um~280 um; thermal insulation layer is PCB aluminum substrate of core technology, it is generally composed of special, polymer filled by special ceramic thermal resistance is small, the viscoelastic performance is excellent, has the ability of anti aging to withstand mechanical and thermal stress of IMS-H01 IMS-H02 and LED-0601 PCB high performance aluminum,The heat insulating layer and substrate is the use of this technique makes it has very good thermal conductivity and high strength electrical insulation properties; metal base is a support member aluminum substrate, is required to have high thermal conductivity, the general is aluminum plate, also can use of copper (the copper plate can provide better thermal conductivity), suitable for drilling, punching and cutting and conventional machining. The process requirements are: gold plating, tin spraying, OSP oxidation, lead-free ROHS process etc.. Material: aluminum substrate product features: The insulation layer is thin, small thermal resistance; non-magnetic; good heat dissipation; high standard thickness of mechanical strength product: 0.8, 1, 1.2, 1.5, 2, 2.5 copper foil thickness: , 3.0mm 1.8um 35um 70UM 105um 140um features: with high heat dissipation, electromagnetic shielding performance, high mechanical strength, excellent processing properties. Usage: LED special power hybrid IC (HIC). Aluminum substrate is carrying LED and device of heat conduction, heat dissipation is mainly dependent on the area, concentrated heat conduction can choose to board with high thermal conductivity, such as the United States Beggs sheet; slow heat conduction or heat domestic material can be. The price is difference , Beggs sheet to produce the finished product probably need 4000 / square meters, general domestic materials 1000 /square meters. LED lamp general use voltage is not very high, the choice of 1mil thickness of insulation layer can withstand voltage greater than 2000V. Radiation reference design methods: why thermal design? The effects of high temperature on electronic products: insulation performance degradation; damage to components; aging materials heat; low melting point weld cracking, the welding points off. Effect of temperature on components: generally, temperature resistance is reduced; the high temperature will reduce the service life of the capacitor; decline in the performance of high temperature will make the transformer, choke coil insulation material, general transformer, choke coil allows the temperature lower than 95C; the temperature is too high。
