The test and structure of washing wall lamp

1,The structure of washing wall lamp:
The power module of LED washing lamp install of external shell,the space is limited,some manufacturers in order save-space 。the dip component replace by the surface component 。this method is not acceptable。The surface welding pin type component is likely to fall off due to weak weld,so for these components as far as possible to take dip package。If has been surface component please use the glue fixed。

2,The test of washing wall lamp
1)Temperature rise test
Temperature test is necessarily project of products safety test,
different standard component has temperature limit。In the product design stage,the manufacturer should attach great importance to the problem of heat dissipation products, especially for some parts (such as insulating sheet etc.) special attention should be paid to。If the long-term work in the condition of high temperature,easy to damage, resulting in a fire or electric shock hazard.The power supply module inside the lamp in a closed small space, heat limited. Therefore, when the manufacturers choice the components,should pay attention to choose the appropriate components according with product specification, ensure the components working in a right range, thus avoiding the components to work close to full load under the condition to produce heat。
2)The aging test
When The LED wall washing lamp production is finish ,the need for LED wall washing lamp for about 24 hours aging test, after aging test should be tested for water resistance at once!

How to choose the LED wall washing lamp

(1) The power size:
The power size of washing wall lamp has decided projection distance,in general has 18W,24W,36W,48W parameters. But power is not fixed。The power can changed According with customer claim,high power LED washing wall composed of the single row led, the LED line cast lamp composed of multi row led。
In addition,because the heat dispel problem, adopt single 1W to make washing wall lamp with 1 meters not more than 36W! otherwise,will be appear light attenuation when heat dispel situation is not good。

(2)voltage:
Can be divided into DC and AC,the in general built-in power external line AC220V(Japan AC110V),external module as low voltage DC24V,DC12V,DC27V etc..
according with the demand 、different product factory and voltage。

(3)IP protection grade:
IP65   6 represents: completely prevent the dust entering
5 represents: not any harm with water washing。

(4) colors specification: divided into colorful, full color, monochrome

(5) the color temperature: about 2200K (amber) 3000K(warm
white)4000K(incandescent)6000K(white)7000K(cool white)

(6) emitting angle:
high power LED wall washing lamp(narrow angle) of the most distant valid projection distance is 5-10 meters。Lighting emitting angle is narrow so project distance more far!

What is the LED washing wall lamp

LED washing wall lamp,the lighting like water washed walls,mainly purpose is decoration of the building。And to draw the outline of a large building。
and to draw the outline of a large building outline! Since LED has the advantages of energy saving, high luminous efficiency, color is rich, long service life, so in the wash wall lamp in 2013 the other light source is gradually replacing LED wall washing lamp. LED wall washer lamp has become one of the important role of modern outdoor lighting, lighting designers used widely most.
LED wall washer lamp also called linear LED cast light lamps and so on, because of its shape is an elongated, also somebody will call the LED lamp, the technical parameters and the LED spot light is broadly similar,compared with the round structure of LED cast light lamps, heat radiating device structure of LED wash bar wall lamp more good processing point.

Mining lamp of cost and benefit assessment

Everyone is know,to compares the high voltage sodium or metal halide lighting as factory lighting。LED mining lamp initial investment cost is obviously a lot to be higher than tradition lamp products。however due to the led has high efficiency lighting source, It is obvious that save-energy feature gave led mining the advantage.

LED mining lamp development solution for plant lighting

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。

Detailed mining lamp installation procedures and precautions

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.

How to purchase the LED save-energy lamp and cast light on living room

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?

choose the living room light
choose the living room light

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.

what is Fiber optic lights

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.

Optical performance specification

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.
