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 lamp power off why would light up
- LED lights turn off the light: 1, the switch is cut off the zero line, you can change the line.2, share change in induction. Switch off zero line with switch.No electricity and no effect on the light, so ignore it.
- 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: The difference between ordinary LED lamp and LED downlight and integration of advantages and disadvantages
- Integrated downlight features:1. strong anti glare than the old lamp;The 2. lamp body adopts integrated design;3. spring elasticity is more suitable for installation;4. new package 2835 beads, can provide high lumen output. Have completed the best quality lamp wafer chip package can provide high brightness output. In many applications, it is very suitable. The design is compatible with the element size, brightness and trust so as to make the design more uniform spot downlight;5. the design of fastener design and opening recognition has been increased in packaging, which improves the reliability of packaging and the convenience of installing holes.
- Q: Excuse me, how to install the LED lamp?
- Pull over the protective device for the lamp, and note that the wire is configured to prevent the conductor from becoming brittle or rodent bite
- Q: The opening 7, 5 cm height of the LED lamp, home decoration into the floor with fear of hydrochlorothiazide
- 75mm hole, downlight height can be controlled in 3W.5W, height of about 50mm, there is a need to ask me.
- Q: How much LED 150W downlight spiral energy-saving lamp replacement
- Ha ha, you need data150W energy-saving lamp with 60-70W LED mining lamp can,
- Q: Turn off the lights after the bright LED lamp
- Because the electrician is working on the power off switch, the power switch is a zero line, not a live wire. Electricians know that the power switch must be cut off by the line of fire, and no danger of electric shock is announced. If the power switch is on fire line, after the power is cut off, the FireWire will continue to supply power to the LED driver. Therefore, the LED lamp will have a faint light when the switch is turned off.
- Q: Common questions about LED downlight spotlights
- Currently on the market Jiezhuang LED downlight is 12--24 DC drive, just some built-in drive, directly connected to the 220V power supply, there is need to use power.
- Q: Why use LED lamp light source patch
- Patch LED because of small footprint, the unit area can increase the number of LED series, which has a small power LED lamps power factor has improved benefits.
- Q: How to judge the quality of LED downlight
- Determine the quality of LED ceiling lamp lighting effect, the United States and Taiwan LED chip chip chip, domestic chip etc.. Different brands, different prices, lighting difference is also large. Special low price downlight, make many use of chip production line down the defective products, color inconsistencies, brightness difference, short service life, users need to pay attention to.
