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: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:LED lamp power off why would light up
- The distribution of capacitor connected switch contacts of parallel line formation (originally existed), after turning off the switch can still trace by alternating currentYou used a small light source lamp power LED lamp (mA current to shimmer)The combined effect of the above.
- Q:LED downlight, embedded lamps, lamp tube and difference?
- At present, these concepts are vague and can be mixed up in the industry
- 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.
- Q:LED lamp is mainly used in where
- Downlight is generally used in shopping malls, offices, factories, hospitals and other indoor lighting, the installation is simple and convenient for people to love. LED downlight downlight all inherited the traditional advantages, less heat, energy saving and long service life, small maintenance costs. The early LED lamp LED lamp due to expensive, the overall cost is very high is not acceptable to the customers. With the decrease of LED lamp chip prices and cooling technology improved, laid a solid foundation for the LED lamp into the commercial field.
- Q:The general living room to Amdo large size of the lamp?
- Now more and more office and family on the use of LED lamp lighting, size depends on the specific size of the size of the living room, the living room, a dozen centimeters can, do not need too much.Because of the more and the applicability of the LED lamp used in indoor lighting more people know, is becoming more and more popular. becauseLED has some other lamps downlight incomparable even other LED lamps can not compare the applicability of indoor lighting LED lamp does not occupy the indoor space in the indoor installation of LED downlight, because hidden lamp, do not use the pressure.

- Q:The difference between ordinary LED lamp and LED downlight and integration of advantages and disadvantages
- Can work in a high-speed state: energy-saving lamps if frequent start or turn off, the filament will blacken, quickly damaged
- Q:The office, sample room, corridor, the most commonly used several LED downlight which is several dimensions, what is power?
- The office uses 4 inch and 6 inch downlight, lighting power within 12-20w, ensure the light illumination to 100-200LUX office.The brightness of the corridor can be slightly darker, with 3-4 inch LED lamp, lamp power in the 6-12W, the more suitable for light illumination to 50-100LUX.
- Q:Common questions about LED downlight spotlights
- LED lamp is a low DC voltage, single lamp voltage can be lit in general about 3.3 volts, general household LED lights have many particle beads, most of which are connected in series, no matter what form of the LED lamp needs a voltage conversion device, this device has the external voltage conversion has built-in, have a stable manifold has stabilized shape, useful integrated circuit is also useful for discrete components do, a complex circuit has simple circuit, a lamp and a conversion circuit package together also has a separate lamp and a conversion circuit, it is all kinds of all kinds, now the country there is no one standard, all manufacturers do, want to make what is what, so it brings inconvenience to the users, so the home LED lights after the damage will be very difficult to get the same, every You should also ask professional staff to press the button, you say the problem is not surprising, it is likely to bring a driver, and the other without driving, need additional driver.
- Q:Steam more business bathroom bath with what LED lamp?
- LED fog lamp, in fact, as long as the structure can reach IP44 level
