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

 

Installment & Application

1) Make a hole

2) Connet the power driver

3) Push the downlight into hole

4) Put down the spring

 

Application

1)Illumination lighting for homes, offices, restaurants, hotels, malls, buses, trains, warehouses, parking lots etc. 
2)Task lighting for cabinets, cupboards etc in your homes, restaurants, and kitchens or any other places where accent lighting is required. 
3)Dispplay lighting for the articles in your stores and shops. 
4)Back lighting for square billboards or advertisement boards.

 

Delivery & Payment

Q: Now there is no replacement of the LED light source lamp?
Yes, the finished product is one, 25 yuan a, excluding postage, 3W
Q: The office, sample room, corridor, the most commonly used several LED downlight which is several dimensions, what is power?
It can be installed LED fluorescent lamp and LED lamp. The lamp power within 12-20w, ensure the light illumination to 150-250LUX office. The brightness of the corridor can be slightly darker, with 3-4 inch LED lamp, lamp power at 6-12W, the light illumination to 70-120LUX, with the Q I can. Answer for you, so doubt
Q: LED lamp power off why would light up
LED lamp power off, will light up, this situation is normal in the 220 electric power supply situation, reason is caused by the distributed capacitance charge discharge line.Because the switch and the lamp is connected with 220V/50Hz AC power supply is normal, directly added to both ends of the lamp, the lamp work light; when closed, switch capacitor and lamp itself and the line is connected to the alternating current of 220V/50Hz, because the distributed capacitance of the charge and discharge can form weak current, the lamp will light.Solution: in the lamp circuit board input end in parallel with a pressure resistance of at least 400V of non-polar capacitor, capacity 0.05 micro method above (if the switch connection is longer, can be appropriately increased).
Q: What is the difference between the LED and the LED lamp ceiling lamp
In appearance, it's just a different shape.If from the use point of view, led ceiling lamp has environmental protection, pollution-free, less power consumption, high light efficiency, long life and so on, it is widely used in urban road lighting.LED downlight belongs to directional lighting lamps', it only on the 'vertical' surface to the light beam angle belongs to light, light is concentrated, contrasting. More prominent objects, higher lumen, but also set off a quiet atmosphere of the environment.Led downlight characteristics: architectural decoration of the whole system and a 'perfect' does not break bad lighting settings, light hidden building interior decoration, the light source is not exposed, no glare, the visual effect is soft and uniform.
Q: What is the role of LED downlight
Compared with other lamps, it is the main installation can be embedded into the ceiling will not affect the overall appearance but also has installed more than spot downlight, past ordinary lamps, in fact is the common use of lighting or other auxiliary lighting, general store with more traditional can replace the lamp
Q: Turn off the lights after the bright LED lamp
Of course are,,In addition, a lamp, and if it is warm white downlight, 7W interval of 1.8 to 2 meters with a 9 watt meter interval, 2 to 2.5 meters in 1, because of the warm white Led light dark light.. If the daylight color (white) led lamp, high point to spacing of 7W or 9W, every 2 meters to 3 meters with a, above two, today I am in the company installed, the effect is very good, very bright, with a larger spacing proposal, after all Led lamp is more expensive, to avoid wasting the resources that can help you save a lot of money, today I am in the company installed 12.8 meters long * 7.45 meters wide, more than 90 square, 1.8 meters vertical spacing and horizontal spacing of 2 meters with a 9 watt Led lamp with fifteen Led lamp, brightness is bright, do not feel the need so, if you are one hundred square pavement, a lamp should be 20I hope I can help you.
Q: What is the size LED downlight
The inches here are inches, not ancient measurements, inches, feet, rulers, etc.. 1 inches =25.4 mm =2.54 cm (1 inch = 2.54cm)So:4 inches =4 X 2.54=10.16cm. About 10cm = 100mm6 inches =6 X 2.54=15.24cm. About 15cm = 150mm8 inches =8 X 2.54=20.32cm. About 20cm = 200mm
Q: Why use LED lamp light source patch
In a large number of automated production, the packaging cost of the patch LED itself and the cost of soldering to the circuit board are lower than those of the small power LED.
Q: Steam more business bathroom bath with what LED lamp?
Select a special waterproof steam lamp can, general ceiling lamp with more. I hope my answer can help you, I hope to adopt!
Q: Know the LED lamp wattage
No, let me see. How do you know?The term "power" is called.
