FAQ:
1.What is COB ?
Chip-on-Board, or COB, refers to the semiconductor assembly technology wherein the microchip or die is directly
mounted on and electrically interconnected to its final circuit board, instead of undergoing traditional assembly or
packaging as an individual IC. The elimination of conventional device packaging from COB assemblies simplifies the
over-all process of designing and manufacturing the final product, as well as improves its performance as a result of the
shorter interconnection paths.
2. What is COB Advantage ?
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

- Q: LED ceiling lamp and LED downlight what is the difference
- The ground is the vertical light lamp, ceiling lamp is light.
- Q: LED is not only the benefits of downlight what harm?
- The characteristics of LED lamp: overall unified and perfect to keep building decoration, without destroying the lamps installed, building decoration light hidden inside, the light source is not exposed, no glare, the visual effect is soft and uniformThe advantages of LED downlight:1, energy saving: white light LED energy consumption is only incandescent lamp 1/10, energy-saving lamps 2/5, longevity: LED theoretical life can be more than 100 thousand hours, for ordinary family lighting can be described as "once and for all"". LED downlight pictures (19)2, can work in a high-speed state: energy-saving lamps, if frequent start or turn off, the filament will blacken, quickly damaged.3, solid state package, belong to cold light source type. Therefore, it is easy to transport and install, can be installed in any micro and closed equipment, not afraid of vibration, the main consideration is the heat dissipation.4, LED lighting technology is changing rapidly, and its luminous efficiency is amazing breakthrough, the price is constantly decreasing. The era of a white LED lamp coming into the home is fast coming.5, environmental protection, without mercury (Hg) and other harmful substances to the environment, will not cause damage to the environment. The assembly parts of LED lights can be easily disassembled and disassembled, and can be recycled by other people without recycling by the manufacturer. LED does not contain infrared and ultraviolet light, so it does not attract insects.6 、 fast response speed: LED fast response, completely eliminates the shortcomings of the traditional high voltage sodium lamp glow process.To say LED downlight drawback is the market disruption of LED products are not up to the specified standard, so the market will have a lot of defects, and the price is low
- Q: 7 square feet of aisle to install 3 LED downlight, how much w led downlight
- 5W*3, the key depends on the ceiling elevation.You can use 3 W
- Q: How much is the general 15WLED lamp luminous flux.
- Usually around 1200lm. Warm colors will be low, cool colors will be high.
- Q: How many good color family LED downlight
- Cool home if the partial blue is not suitable in not too bright, looks like a wildfire.
- Q: What brand of downlight is good? Please explain the reason, thank you!
- Cost.

- Q: Led downlight can light panel directly with intelligent dimming Mody?
- We live by 220 volts of alternating current, and LED by direct current. So all the LED lights will be fitted with a driver to change the current and the voltage. LED lamp dimming according to the change of current or voltage, so Led can directly drive panel light lamp dimming and decided to use intelligent downlight! Ask the supplier can, but generally adjustable lamp will be specified, because the adjustable light is not adjustable to your light!!
- 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: LED downlight, embedded lamps, lamp tube and difference?
- I. definitions1, downlightThe lamp is generally a lamp holder, lamp can be directly mounted incandescent or energy-saving lamps. Is a lamp embedded into the lighting ceiling light shooting style. Its biggest characteristic is to maintain the overall unity and perfection of the building decoration, not because of the setting of lamps and lanterns, and destroy the perfect unity of ceiling art. The recessed luminaire, mounted inside the ceiling, projects all the light downward, directly to the light. Different light effects can be obtained with different reflectors, lenses, louvers, and light bulbs. Table space, can increase the space of the soft atmosphere, if you want to create a warm feeling, can try a lamp lamp, reducing the spatial sense of oppression. Generally in the hotel, family, coffee shop use more.
- 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!!
