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:How much LED 150W downlight spiral energy-saving lamp replacement
No matter where you use it, in general, not less than 50W LED lights can be, if not white, power needs to increase a little.
Q:7 square feet of aisle to install 3 LED downlight, how much w led downlight
My experience with choosing lights was W, and the bigger the headlight. As far as my family is concerned. All unified outfit is downlight 3W downlight. Open your mouth. It's enough
Q:LED lamp is mainly used in where
Shopping mall. Just walk a lot and a lot of LED downlight.
Q:Now there is no replacement of the LED light source lamp?
Yes, it depends on what level you want. I can solve your problem with a net name.
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 much is the general 15WLED lamp luminous flux.
Mainly depends on what you apply products, parameters vary.1, high-power 1W single 110-120lm to remove the loss of 1600lm2, 5630 0.5W, single 50-55lm, removal of loss 1400lm
Q:LED is not only the benefits of downlight what harm?
Not good manufacturers can only be said to be defective, LED competition in the domestic market is too large, resulting in product quality, now there LED manufacturers can LED lamps prices do with energy-saving lamps are almost the same, I smiled, this is the difference
Q:The general living room to Amdo large size of the lamp?
Look at the size of the living room ceiling. Class one is. 10 cm downlight
Q:How many good color family LED downlight
Personally feel about 3500K color temperature appears soft and warm. I hope it works for you
Q:How are LED lamp quality is good or bad?
Drive power. A good driving power can guarantee a whole lamp life, theory of life LED lamp is 100 thousand hours, and the driving power of general life ranging from less than 50 thousand hours. So in order to ensure the whole lamp life, LED lamp manufacturers tell you that the driving power is very important, and it is also one of the most critical components. On the other hand LED downlight must be a constant current power supply, if using constant voltage power supply low cost will greatly shorten the service life of LED lamp. Then, how can we identify the constant current power supply? You can see several parameters, service life, light, light effect and warranty period. If the service life is longer, the quality of the power supply will be relatively better.
