LED lights of the ten major advantages: First, the lamp body is very small LED lights are very small, very fine LED chip package in the transparent epoxy inside, so it is very small, very light, in the production and application can save a lot of material and space. Second, the energy consumption is very low LED lamp operating voltage is generally only 2 ~ 3.6V, operating current as long as 0.02 ~ 0.03A. That is: it consumes no more than 0.1W of electricity, the consumption of electricity than the same luminous incandescent lamp to reduce more than 90% Lamps are reduced by more than 70%. LED Third, sturdy and durable LED chips are completely encapsulated in the epoxy resin inside. Small epoxy resin particles extremely difficult to break, the entire lamp body is not loose part; inside the chip is extremely difficult to break, but also little heat effect and may volatilize, fuse. These features make LED difficult to dam...
In the LED production of the problem is the chip package, the cup of bubbles occupy a large proportion of bad, if the production bubble is not well resolved or control, it will cause the product to accelerate the decay of a factor, which will show the IV Decrease, IR becomes larger, VF rises. Affect the bubble generation factors are more. In the general case, the process is mature, the bad proportion of the bubble will not be too high. If the cup has bubbles, you can give the cup a certain percentage of glue, and then in the next process. The following are the relevant factors: 1. The temperature and humidity of the environment have a greater impact on the bubble. 2. The temperature of the mold is also a factor in the generation of bubbles. 3. Bubble generation and process adjustment has a great relationship. For example, some factories do not have the same vacuum without bubbles, and there is a bubble in this factory even if there is a vacuum, ...
L/B is the standard definition of LED lamp life. 50000h (L85 / B10), that is, 10% of the product luminous flux output to the initial value of 85% or less when the time is 50,000 hours. In turn, it means that LED products with 50,000 hours after the work, there are still 90% of the product light failure less than 15% reliability. 50000h (L80 / B50), that is, 50% of the product luminous flux output to the initial value of 80% or less when the time is 50,000 hours. Refers to the LED lamps work 50,000 hours later, there are still 50% of the product light fades less than 20%. In general, to achieve this indicator of LED lamps, you must use world-class LED chip, the use of higher thermal design, 25 ° C ambient conditions, LED lamp chip junction temperature control within 60 ° C can be done.
Compared with the previous incandescent and energy-saving lamps, LED lamps can be described as a lot of advantages, its use of longer life, but also more energy saving. In addition to see the parameters of the lamp (wattage, life, color temperature), but also should pay attention to meet the following three functional requirements: 1, the function of lighting. Color temperature is different, the impact of light effects are also different. In general, the color temperature is greater than 5000k for the cold light, color temperature between 3000-5000K for the warm white, color temperature is less than 3000K is warm. Home lighting is generally used for warm light, because the warm reminiscent of fireplaces and fire, it is warm and peaceful. 2, eye function. Stroboscopic damage to the eyes of a huge, especially in the light of a long time to study and study people, need attention. In addition, the LED, i.e., the light emitting diode, is made...
1. Random lighting control, the use of dimming software, press a few buttons can remote control all room lighting. 2. Full open function can be easily achieved lights and electrical appliances a key full and a key full function. 3. Scene lighting function According to user needs to set the home, dinner, theater and other lighting scenes.the combination of the settings of the lighting switch, brightness.
A recessed light or downlight (also named pot light in Canadian English, sometimes can light (for canister light) in American English) is a light fixture that is installed into a hollow opening in a ceiling. When installed it appears to have light shining from a hole in the ceiling, concentrating the light in a downward direction as a broad floodlight or narrow spotlight.. There are three parts to a recessed lighting fixture: housing, trim and bulb. The trim is the visible portion of the light. It is the insert that is seen when looking up into the fixture, and also includes the thin lining around the edge of the light. History: The earliest recessed lights were developed in the 1950s by Ivan Kirlin of the Kirlin Company, Detroit,Michigan. Advantages: Recessed lighting offers the advantages of being a hidden light source and energy efficiency. However, the tradeoff is that they are relatively permanent and may be unflattering. (From Wikipedia,...
Global lighting leader Philips Lighting announced that it will launch a unique interconnection LED road lighting project. Philips Lighting will install intelligent interconnected LED road lighting systems in the picturesque Dutch island of Amerland and use Philips ClearSky Spectroscopy to protect migratory living conditions. The newly installed lighting facility can save energy, reduce light pollution and help Amerang Island achieve its sustainable development goals. The project is also Philips Lighting for sustainable development to make another major achievement. The newly deployed road lighting system on the island uses Philips ClearSky technology to emit shallow blue-green light. The light in the human nighttime activities required to provide lighting at the same time, will not affect the lives of birds and nocturnal animals. Smart Led Light (2) Ordinary white light will affect the direction of the bird organs, so that...

(1) factors that affect the LED downlight beam angle A.LED package appearance shape; B. The chop chant structure; C. Chip and its structure; D. Refractive index of encapsulated glue; E. Material quality consistency; F. The encapsulation process (ie, the height of the chip); (2) how to wrap a good angle - first of all have a good design A.LED mold roundness roundness consistency is better; B. Stent cup and cup size memory smoothness is better; C. Selected chip D. Select the appropriate refractive index of the glue;
With the LED lighting technology continues to progress, LED lighting because of its long life, environmental protection, energy saving lamps, no ribs and other characteristics of more and more light box manufacturers love. Let’s Analysis on the Cause of Fire of Rolling: Use a thin line, the line is overloaded. Each wire has a safe current that can be carried per square, and once the amount of current passing through the wire exceeds the safe current, it can cause the instantaneous heat of the wire to be too large, causing the wire to catch fire. For example, some of the market use of the shutter light 0.75mm wire, when used in the first time even if the main line, it will cause the circuit overload, the wire for a long time through a large number of current, it is easy to lead to roller curtain light, The Proposed to use 2.5mm ² line, to avoid the cable caused by too much security risks. Improper use of the line, resulting in short circ...
