COB led down-light is a kind of LED light source lighting equipment.

The characteristic of COB led down-light are as below:

1. Keep the overall unity and perfection of architectural decoration, do not destroy the setting of lamps, the light source hides the interior of architectural decoration, the light source is not exposed with no glare.

2. Energy-saving: 1/4 of ordinary energy-saving lamps consume the same brightness. Environmental protection: It does not contain harmful substances such as mercury, and does not pollute the environment.

3. Economy: The cost of lamps and lanterns can be recovered for one and a half years because electricity saving can reduce electricity expenditure. A family can save tens of yuan on electricity bills a month.

4. Low Carbon: Saving electricity is equivalent to reducing carbon emissions.

5. Longevity type: The life of LED lamps is 50,000 hours, and the life of LED lamps is 20 years if they are used six hours a day.

Advantages of COB led down-light:

1. Energy-saving: White LED energy consumption is only 1/10 of incandescent lamps, energy-saving lamp 2/5, longevity: LED theoretical life can exceed 100,000 hours, ordinary family lighting can be described as "once and for all".

2. LED barrel lamp can work at high speed: if the energy-saving lamp is frequently started or turned off, the filament will be black and quickly damaged.

3. Solid-state packaging, which belongs to the type of cold light source. So it is very convenient to transport and install, can be installed in any micro and closed equipment, not afraid of vibration. The main consideration is heat dissipation.

4. The technology of LED lamps and lanterns is progressing rapidly. Its luminous efficiency is making an amazing breakthrough, and its price is constantly decreasing. The era of white LED lamps entering the family is rapidly approaching.

5. Environmental protection, no mercury (Hg) and other harmful substances to the environment, will not cause damage to the environment. The assembly parts of the LED lamp can be easily disassembled and assembled. They can be recovered by other people without the need of the manufacturer's recycling. LED does not contain infrared and ultraviolet rays, so it does not attract worms.

6.Fast response speed: LED has fast response speed, which completely eliminates the shortcomings of long start-up processes of traditional high-pressure sodium lamps.
