1、 the introduction:
In the plant energy consumption, in a great measure is lighting energy consumption. For example, in a 40000 square meters factory buildings, lighting electricity load is about 400KW, therefore, in the selection of factory lighting, how to realize the energy saving, environmental protection is placed in the plant designers an important topic. Lighting using new LED light based, in addition to energy saving and environmental protection, it also has the advantages of long service life, fast response time, pure light color light concentration and other advantages, in recent years, widely favored by consumers.

2、the key technology of LED lighting design
New technologies, new materials and new technology constantly applied to the design of high-power LED light source, which laid a solid foundation for the design of high power LED lamp. Due to the LED light source application product difference is bigger, its design, testing standards with a delay, so lead to different manufacturers to produce products exchange poor in structure, performance and other aspects.Meanwhile, the integration itself is a machine, light, electricity and other factors of LED lighting products, and its design is related to technology in many areas.

3、power selection
Traditional mining lamp with a 250W or a 400W high pressure sodium lamp and metal halide lamps are compared, characteristics and model of the LED lamp, with obvious differences, see table:Considering the high (voltage)pressure sodium lamp in practical use and metal halide light attenuation and two light, the actual light-emitting efficiency is much lower than the 80lm/W, often cannot reach the nominal 70%. So we first developed LED mining lamp power setting is about 120W, once the light effect in line with expectations, that is, than the traditional lamp energy saving more than 50%.

lighting        color            color        service
efficiency(lm/W)     temperature(k)   rendering index(Ra) time(h)
Metal halide
lamp         80        3000/4500/5600   60-95        8000

High voltage
sodium          80         1950/2200/2500     <30            8000

LED         >100        full color temperature >70       >30000

4、Dissipate heat design
In the high-power LED, the Dissipate heat is a big problem. For example, a 10W white LED if its lighting – electric conversion efficiency of 20%, there 8W electric energy is converted into heat energy, if not add heat – dispose measures, the power LED is the rapid rise in core temperature, when the junction temperature (TJ) temperature rise exceeds the maximum (usually 150 ℃), high power LED will be damaged due to overheating. Therefore, thermal design is our most important work, below we respectively from two aspects of the aluminum substrate and radiator combination, to investigate the thermal design.radiator is to absorb the heat sink substrate or chip pass over the heat, then diverge into the external environment, to ensure the normal temperature of the LED chip. The vast majority of radiators are designed to be applied to natural and forced convection conditions。 Namely active and passive radiator heat sink。

Mining lamp installation steps:
The first step: pre-installed hook at install the mining lamp position,(hook can be match with the hook rings to work, in addition to ensure the hook can be carrying capacity to more than 30kg)。
The Second step: put the hook ring of mining lamp into hook，thus the mining lamp lifting up by the hook rings。
The third step: the power line from the construction site the mining line has connected to the power supply line of the lamp, accordance with the “brown–L””blue—-N”” yellow — ground” principle connected，and to finish the work that water proof and insulated。
The fourth step: switch on the power, to confirm whether the normal work of industrial and mining lamp;
The fifth step: after confirm the lights without error, install is finish.
Note of mining lamp installation:

1 installation of mining lamps or replacement parts, must first disconnect the power supply;

2 connect the power, should pay attention to the input voltage and the mining lamp adapter, power line connected, must make relevant waterproof and insulation processing.

introduction: The paper summary of led save energy install importance point。Allowing readers to easily understand the decoration lamp tips，not limit the ordinary energy-saving lamp and incandescent lamp, more choice way to application the energy saving lamp and cast light on decoration。introduction: The paper summary of led save energy install importance point。Allowing readers to easily understand the decoration lamp tips，not limit the ordinary energy-saving lamp and incandescent lamp, more choice way to application the energy saving lamp and cast light on decoration。In the post, many people like to choice ordinary energy-saving and incandescent lamp for home furnishing decoration。The two kind of light source is not friendly environment and energy saving。With the development of the LED lamp technology maturity。 In my personal experience, we recommend the use of LED energy saving lamp is more suitable. Which adopt most energy light source in current。What point need we to consider when purchase the light source?

1、according to the floor height selected the size of energy saving and downlight。Different patterns of the family living room height is different 。so we first determine to be determined is the clear height and then select a different the living room ceiling lights. In generally such as ceiling is less than 2.7 meters in height living room ,we try used

2、5-inch LED downlights and 3.5W energy saving lamp。 (in past used ordinary 8W energy-saving lamps or 25W incandescent lamp, now use 3.5W energy saving lamp is enough)。If the ceiling height is 5~8 meters of hall building。We consider choice of more than 6-inch downlight and 11W or 15W LED energy saving lamp, if brightness is not enough, whole the living room appear dim。

3，the selection of light color and light color temperature: the home furnishing lamp main used the warm white lighting and yellow lighting in currently led market。The lighting source is same between the LED energy lamp and traditional lamp，can be used warm white lighting and yellow lighting。The color temperature of warm white lighting and yellow light as 6000~6500K。we can use multi-color when decoration of home furnishing。
for example: white light and yellow light intervals using, divided into two groups at the beginning of the installation. If a single installation of white lamp, white lamp call the cool white, in the winter time, the beginning of the white light always felt gloom feeling. So be install the warm white so on.

3、Choose downlight material. There may be a lot of people would choose the milk white light the lamp surface in the decoration, because my downlights light milky white face is made ​​by EFI(电渡), so the downlight’shell will be tend to be yellow after a period of time。We recommended to use silver or other colors. Use less smooth, and use drawing surface based. And try to use aluminum material, do not choose plastic. If the home is the simple decoration, color to the now popular home deep Coffee as based color, so that the square is a good choice. If the house is a modern minimalist style of decoration, round should be your good choice.

4、Noted that matters
We need to understand is that no matter what kind of shape the living room lights, mainly to see the lines constitute the main decoration of your home, the size of the space and height. If you are at home in the corner using plaster line is very gentle curvature of the form, then select the square is not a problem. For instance, your home furniture is Chinese and angular classical style, then circular downlights and LED energy-saving lamps can also be fitted.

Fiber optic lights are a special polymer compound as a core material with high strength transparent flame retardant engineering plastics for the skin, can guarantee the fracture does not occur for a long period of time, deformation and other quality problems, services time of at least 10 years. Due to the high purity of the core material, thus effectively reducing the attenuation of light transmission, to the efficient transmission of light, because of its high purity, low attenuation, and easy installation. Reliability, safety, environmental protection, flexibility, integrity, and can produce colorful, dreamlike visuals and no UV, low heat, no electricity hurt, rich and long services time, color changes, good durability and plasticity characteristics. It is seen as an ideal material for an alternative to the existing decorative lighting instruments.

Fibre is a special high-purity resin (poly methyl methacrylate) as a core material in order to effectively reduce the attenuation of light, achieve high efficiency of light transmission.the optical fiber with high strength, high transparent, flame retardant engineering plastics (PVC) for skin. To ensure that optical does not occur fracture or Deformation of quality problems on long time. Optical fiber transmission loss less, light and strong, easy to maintain, durable. The light emitting part Don’t make heat and not occur charged。does not exist ultraviolet and And the use of optical fiber can change the physical properties of light straight line transmission, the light guide to what we need to place, and output colorful light. In the actual use of the optical fiber head will need to be connected to the light source device. Just to set the source function can change the optical light and dark. Or Color change etc.
Optical fiber long service life, so as to avoid complicated maintenance work in future。 (in outside the fiber also can be used for 10 years)

Fiber products are divided into: side light.φ 18. φ 14. φ 10.

End glow. φ 18 φ 14 φ 10 φ 6 φ 2.2. φ 1 φ 0.75 specifications.

Side point optical fiber. φ 1.5. φ 1.0. φ 0.75 specifications.

Side glowing optical fiber:φ18. φ14. φ 10 can be used for building houses. Such as: building. A monument. Bridge. Guta can beautify the city image, but also can improve the visibility of the building. Side glowing optical fiber can be used in hotels. The hall. Park. Square corridor. Aisle. Stairs lighting. Can be used on the bottom of swimming pool. The pool. And aquarium. The underwater world of lighting and decoration.Side emitting optical fiber:φ18 φ14 φ10 φ6 can be used for the Museum of cultural relics. Jewellery. Gold and Silver Jewelry Showcase exhibition lighting. Because the radiation optical fiber lighting don’t have ultraviolet and infrared. So to avoid the exhibits caused accelerated aging by the lighting。To guarantee the security of exhibits. Because the fiber optic lighting itself is not charged with high safety performance.It can also be used for those special environment indoor lighting. Such as the basement.Coal mine. Oil depot safety coefficient high places.Side emitting optical fiber φ 1.5. φ 1.0.φ0.75 can be used in hotels. Hall， The hall， The bathroom ceiling。 With twinkling stars. Shine bright. Dynamic color changes。 The characteristics and magnificent, is incomparable with the other lighting way.We are currently producing fiber waterfall. Optical crystal chandeliers for hall， Conference hall. The entertainment center and other places which reveals the magnificent， Noble and elegant。Because the light is to do linear motion, so the fiber in the practical application is not to do 90 degree right angle turn. The lowest angles as multiples of the diameter of fiber. To avoid the loss of optical fiber inner light.

                             Led Fiber optic light source machine

Refer to the downlight lamp，in order achieve greater development in the field of indoor lighting。We should consider the following principles and directions:
1，To put the use the LED dwonlight faster starting，convenient to adjust lighting advantages，priority of application : requirement for sound，light in self-control and require  adjust light or frequently switch lights and other places。
2，Should be select the spot, expanded step by step, escalate，sum up experience，avoid to not the analysis conditions，large area promotion。base on downlight advantage as entry to find suitably work spot。
3，utilize the advantage of LED color lighting，used in the indoor decoration for higher requirements，or as the ceiling decoration, background lighting etc…
4,LED downligh lamp shall accordance with the 《architectural lighting design standards》requirement, including illumination, uniformity, glare, color rendering index requirements and affordable color temperature to achieve good visual conditions and limits specified LPD.
5，Using LED downlight lamp directional emission light characteristics, applications that require directional lighting parts, such as supermarkets, jewelry counters, and so on.
6，We consider that LED downlight should highlight the energy-saving effect: in currently ,to replace the inefficient incandescent lamp is first goal。The second goal is replace the halogen; third is to try to gradually replace the compact fluorescent lamps. Special Note: Not all of LED is energy-saving lamp，should be reaching the same level of illumination, to compare the quality of lighting conditions.
With the development of the LED industry is mature, The LED downlight lamp industry and market will be to gradually opening ， LED Lighting projects  has chance acceleration of replace the traditional incandescent lamp, energy saving lamp lighting products.

1. The LED bulb requirement
   Because of the need to replace the incandescent，so must have at least the following requirements:
   The wattage is reference standard without lumens for the LED incandescent。the led luminous is Continuous to progress。The power of led does not representation of LED luminous 。the incandescent most commonly to using type has 15 watts, 30 watts, 45 watts, 60 watts, 75 WATTS and 100 watts etc。if only to discuss the led luminous，then can be calculated with the luminous efficiency of LED。The LED light efficiency of incandescent as 7.5-12lm/W。the high watts give birth to greater the LED light efficiency。correspondence of parameters between the led watts and led light efficiency, can be list as follows。

Wattage W  15   30    45    60   75   100
Incandescent Efficiency 7.5   8   8.5   9.5   10.5   12
LM         112.5 240   382.5 570   787.5 1200
LED1         Wattage W   1.56  3.3 5.3 7.9   10.9   16.6
LED2         Wattage W   1.2  2.6  4.1   6.1   8.4   12.8

led replacement lights

NOTE:Filament lamp= electric incandescent lamp

If using led replacement lights, can also draw the correspondence wattage。But the LED efficiency is continuous progress, so it is difficult to give a exact figures。Assume now commonly used LED1, the light effect is 100lm/W, if the highest light effect of the LED2, the light effect is 130lm/W (warm white light effect will be less than this value). We can draw on the two kinds of light effect LED。But because LED needs constant current source, and the constant current source has a certain efficiency, assumed to be 85%, and because LED cannot use the transparent bubble shell, but only the use of creamy white foam shell. Its light transmittance of about 85%。Multiplied by two equals 0.72。After considering the factors above. We can draw the correspondence of incandescent lamps wattage。 As shown in the table, the power LED2 can save 10 times in about the same brightness。 Have a bit need special explanation. Is from the current LED bulb lamp light efficiency and heat dissipation, it is impossible to do more than 10 watt, in other words,there is only 60-75W can replace incandescent lamp LED bulb. Of course, the PAR lamp is another matter (which will be discussed below) 。
The following basic index of LED bulb power supply:
1，Basic types of power: Mainly consists of isolated and non isolated, refers to the load part is isolated from the Firewire(AC part)。in general，no isolated not has transformer，so the cost is low, but the requirements of high pressure aluminum plate，otherwise there may be charged on the radiator。So it is not easy through the safety inspection。Isolation mode is more safe，more easily through the safety inspection, but the cost is high。
2，Power supply output power: The size must be same between LED bulb and incandescent lamp。So limited the size of radiator，at present, no more the 9W。
3, Power efficiency: In general isolated mode in about 80-85%, non isolated in about 90%。
4，Power factor(PF): about 0.5-0.6 without PF correction，Has PF correction at around 0.9-0.99
5 Size: because the bulb to the power of the space is very small, so the volume restrictions are very strict。

According to Various of bus protocol system，in addition to DMX512 and DALI deeply into the internal of lighting products。Other protocol just only to the wall of the connector and socket，not In deeply to internal of lighting products。In other words hadn’t unified standard according to the characteristics of various lighting and lighting terminal products, it is impossibility of open the function of lighting products。So，on one hand，they are only general simply on-off control and phase chopper。So ，has the very big limitation in the intelligent application of ordinary to office and family。and limited them to enter the general lighting market。On the other hand，because there hadn’t unified standard according to the characteristics of various lighting and lighting terminal products。And not have to in deeply to internal of lighting products。For various of lights products input supply to general simply adjustments to achieve the dimming purposes。Is easy to appear the lights flashing。Damaged the ballast controller or tubes，etc.， and even produce a security problems.Although the DMX512 into the internal of lights product。but the system is mainly for large stage lighting lamp design, many functions of the main consideration is the motor mechanical control, and no more consideration for the electric control by program cord。It’s not suitable for the ordinary office building lighting and household lighting in intelligent application。But some lights products with DALI digital addressable lighting interface。So as international unification standard into the intelligent ordinary office light and ordinary family light。The DALI digital addressable lighting interface is most promising， high quality and intelligent lighting control system。 The rapid development of DALI digital addressable lighting interface technology and DMX512 lighting technology application to update play a tremendous role in promoting。
