Description

A LED light bulb with efficient heat dissipation

technical field

The utility model relates to the technical field of lighting appliances, in particular to an LED light bulb capable of efficiently dissipating heat.

Background technique

With the improvement of LED performance and the reduction of cost, lighting products using LED as light source have achieved rapid development, and have gradually replaced traditional lighting products in some indoor and outdoor lighting places. In traditional lighting products, incandescent bulbs are the most commonly used general-purpose light source. Since the luminous efficiency of incandescent bulbs is very low, only about 151m/W, the use of LEDs to replace incandescent bulbs will have significant energy-saving advantages.

However, a problem with LED itself is that the light efficiency of lamps is greatly affected by the junction temperature of the chip. A higher chip junction temperature will lead to a significant decrease in luminous efficiency and will affect the service life of the LED bulb. Therefore, solving the heat dissipation problem of the LED light bulb is very important for improving the performance of the LED light bulb. Because traditional light bulbs rely on the high temperature radiation of the filament itself to achieve light, there is no need for heat dissipation. This leads to the limitation of the size of traditional bulbs when replacing traditional bulbs with LEDs, resulting in less space available for heat dissipation in LED bulbs.

Therefore, how to make full use of the structural space of the traditional light bulb so that the LED light bulb can not only meet the lighting standard requirements, but also provide sufficient heat dissipation space is an urgent problem to be solved in the structural design of the current LED light bulb.
