Description

An LED ball light

technical field

The utility model relates to the technical field of LED lamps, in particular to an LED ball lamp.

Background technique

Since incandescent lamps and electronic energy-saving lamps still occupy a very high proportion in people's daily use, in order to reduce waste, LED lighting manufacturers must develop LED lighting products that conform to existing interfaces and people's usage habits, so that people do not need to replace them. A new generation of LED lighting products can be used under the condition of the original traditional lamp base and line. So the LED bulb came into being. The problem of poor heat dissipation performance of the existing LED bulbs for a long time is generally passive heat dissipation. The main method used is to export the heat generated by the LED chip in the LED lamp, and then the heat is exported through the heat dissipation device. It is a passive air-cooled heat dissipation method. This passive heat dissipation method cannot dissipate the heat generated by the LED chip compounding well, resulting in the LED chip running at high temperature, which affects the LED chip and reduces the LED light. The service life of the LED ball light bulb is long, and because the LED ball light bulb is an energy-saving low-power lamp, it cannot concentrate the light generated by the LED ball light bulb to increase the illumination brightness of the LED ball light bulb.
