Description

LED light bulb with high heat dissipation efficiency

technical field

The utility model relates to the technical field of lamps, in particular to an LED light bulb with high heat dissipation efficiency.

Background technique

LED light bulbs are widely used due to the advantages of energy saving, low carbon, long life, good color rendering, high luminous efficiency, good luminous effect, and fast response. However, the heat dissipation problem is an important problem that LED bulbs need to solve. The quality of the heat dissipation effect is directly related to the luminous effect and life of the lamp. The heat of the LED bulb is concentrated in the small-sized LED chip, which will make the internal temperature of the LED chip higher and higher, which will not only accelerate the aging of the lamp, shorten the service life, and even cause the chip to burn out in severe cases. Especially for LED light bulbs, the heat dissipation structure design of the existing LED light bulbs is traditional and old, and almost all of them are fully sealed structures, which can only rely on radiators to conduct heat, and the heat dissipation effect can be imagined. There are various heat dissipation measures for LED light bulbs, most of which only add some heat dissipation components to the outside to promote heat dissipation. This design is more cumbersome and complicated, and the heat dissipation effect is not ideal, which affects the service life of LED light bulbs.

Therefore, how to realize an LED light bulb with a novel and reasonable structure, multi-channel ventilation structure to form a spontaneous airflow to quickly remove heat, and high heat dissipation efficiency is a technical problem to be solved urgently in the industry.
