What is COB?
Chip on Board, or COB, refers to the semiconductor assembly technology where in the microchip or die is directly mou nted on and electrically interconnected to its final circuit board, instead of undergoing traditional assembly or packing as and individual IC.
The elimination of conventional device packaging from COB assemblies simplifies the over all process of designing and manufacturing the product, as well as improves its performance as a result of the shorter interconnection paths.
What is COB advantages?
1) Reduced space requirements.
2) Reduced cost.
3) Better performance due to decreased interconnection lengths and resistances.
4) Higher reliability due to better heat distribution and a lower number of solder joints.
5) Shorter time-to-market.
Main advantages of LED downlight
1. High efficiency and energy-saving compared to conventional fluorescents which are equal bright, and consumes 70-80% less energy.
2. No RF interference, no buzzing noise, no UV radiation.
3. No fluorescent flickering.
4. No hazard of mercury or lead entering the environment.
5. Low power consumption, high intensity, low lumen attenuation.
6. Recessed mounted, maintenance free, easy installation.
7. Solid- state, high shock/ vibration resistant

- Q: LED is not only the benefits of downlight what harm?
- LED lamps are not in good order, so the government's attitude is right. Now the LED lamp light is concentrated, contrasting. Environmental protection, without mercury (Hg) and other harmful substances to the environment, will not cause damage to the environment. LED lamp assembly can be easily disassembled, no manufacturers recycling are available through other people recycle. LED does not contain infrared and ultraviolet light, so it does not attract insects. LED downlight is a photoelectric (www.heg-led ) of LED lighting products specializing in the production of a series of novel styles, are sought after by consumers. Specific details, you can understand, and I believe it will be of great help and inspiration to you.
- Q: Excuse me, how to install the LED lamp?
- Installation installation method 3 inch downlight LED you can refer to EPCOL, thank you! Hope to be helpful to youA: check the manual, to understand the basic features of LED lamps:Two: installation of lamps and lanterns preparation work:Turn off the main power supply. Make sure the power is off and safe operationLook at the wiring, check the upper part of the ceiling line, the line pipe, if necessary, pull the wire to the place where the lamp needs to be installedPay attention to the groove, without sharp edges and burrs, so as not to scratch the power cordDetermine the line diameter of the cable according to the load,
- Q: How much is the general 15WLED lamp luminous flux.
- Look at the product parameters, and if it's done with a single 1W, it's probably around 1600LM,
- Q: Led downlight can light panel directly with intelligent dimming Mody?
- No, the LED dimming should be adjusted in its drive circuit
- Q: How to choose the right LED downlight
- Look at the power supply lamp (commonly known as: transformer) transformer quality also determines the whole life of the lamp, lamp used more than 50000 hours no problem, but if the transformer is destroyed, the whole lamp will not light up. The electronic components and design scheme in the transformer determine the efficiency, power factor, stability, temperature rise and service life of the transformer. Our driver is wide voltage drive, and the output current and voltage are stable.
- Q: How are LED lamp quality is good or bad?
- 3, light. Good LED lamp 25000 hours before the light is less than 30%, the main factors are the light source and the light however decided the quality of radiator. And better light sources have foreign CREE and so on.4, light effect. Luminous efficiency is the lumen number per watt, in units of LM/W. It is the reaction power saving performance of LED downlight. The better the power saving performance, the higher the light efficiency will be.
- Q: Excuse me, how many different sizes for LED lamp lumens
- See customer needs and in what place, with the output of the LM itself and quality of reflective glass beads, beads arranged, there is a direct relationship between the transparent mask
- Q: LED downlight, embedded lamps, lamp tube and difference?
- No LED lamp lens, no light, light uniformity, light angle.LED recessed lamp is in accordance with the method, there are two types of installation and embedded installation. The recessed lamp is mounted inside the ceiling.LED cylinder spotlights have lenses, focus light, first focus on a place to illuminate, and where the illumination is high.
- Q: Steam more business bathroom bath with what LED lamp?
- LED fog lamp, in fact, as long as the structure can reach IP44 level
- Q: There are no holes 7 cm, 9W led downlight
- Between general 7-12W hole 9.5 cm can be chosen, the LED lights our company own, opening 9.5 cm, 9-12W, 7W ceiling light is also your choice, to choose a bright power point, brightness not too big, choose a smaller power good enough!!
