Description

A LED lamp with heat dissipation base

technical field

The utility model relates to an LED lamp for lighting, in particular to an LED lamp with a heat dissipation base.

Background technique

LED (light-emitting diode) lamps have gradually replaced traditional high-energy-consumption lamps, such as fluorescent lamps and incandescent lamps, because of their low energy consumption and high brightness, and have gradually become popular in people's daily life. With the development of LED technology, the energy consumption and heat dissipation of LED lamps need to be reduced. Now various companies are researching various LED lights to meet people's different needs for LED lights on different occasions.

The biggest advantage of LED lamps is energy saving and environmental protection. The luminous efficiency reaches above 100lm/W, while ordinary incandescent lamps can only reach 40lm/W, and energy-saving lamps hover around 70lm/W. Therefore, with the same wattage, LED lamps will be much brighter than incandescent lamps and energy-saving lamps. The brightness of a 1-watt LED light is equivalent to about 2 watts of energy-saving lamps, and the 5-watt LED light consumes 5 degrees of electricity for 1000 hours. The life of the LED light can reach 50,000 hours, and the LED light has no radiation.
