LED lights are a kind of lamps and lanterns are more durable and brighter than traditional light bulbs.

1, LED is a - a semiconductor diode that can convert electrical energy into light energy. LED and general diodes, like PN junctions, is also a one-way conductive. After the forward current is applied to the light-emitting di_ tube, will be injected from the P region into the N region of holes and N region into the P region of electrons, in the PN node around a few microns, respectively, with the N region of electrons and P region of holes were compounded, thus forming a spontaneous fluorescence. In different semiconductor materials, electrons and holes are in different energy states.

2, low power consumption: LED is a low-voltage operating device, so in the same light intensity conditions, the power loss is minimal, which can significantly reduce energy consumption. On the contrary, future technology and materials will improve its luminous efficiency. Some estimates, Japan's street lights are all replaced with LEDs, can save two large power plants, which is very beneficial to environmental protection.

3, the light source is LED diode, is a new light source technology. LED lights have good heat dissipation, LED lights have a conversion rate of up to 100%, and a long life, and are easy to use.

for home lighting. Many light-emitting diodes can replace spiral or energy-efficient electric lamps in the power range of 5-40 Watts to 60 Watts. Some can also replace high-energy electric lamps, such as a 13-watt lamp with the same light intensity as a 100-watt hot incandescent lamp. LEDs are also available in a wide range of colors, but they consume less power and are less expensive to maintain. White LED bulbs are currently the market leader at the low end of the domestic market, such as flashlights, solar garden lights, pedestrian lights, bicycle lights, etc. LED bulbs are mainly used for traffic signals and for festivals.

High power LED lamp heat dissipation performance factors

LED lights have features such as energy saving and environmental protection, but the actual operation process is easy to generate a lot of heat, once the heat can not be discharged, it is easy to have a high temperature resulting in abnormal chip heat, light source decline and reduced lamp life, etc. In simple terms, the LED lamp thermal management structure is mainly chip-level sealing, packaging level and system integration thermal level.
