Description

Improved structure of LED bulbs

technical field

The utility model relates to a structure of an LED light bulb, in particular to an improved LED light bulb structure in which a light source body and a heat dissipation cover of a lamp are in a special shape, can be directly used as a lighting fixture, and can improve heat dissipation efficiency.

Background technique

Traditional indoor bulbs are mostly tungsten bulbs, quartz lamps, or halogen bulbs. However, these bulbs not only have a short service life, high failure rate, but also high energy consumption, so they are no longer in line with the current trend of energy conservation and environmental protection. Moreover, the existing MR16 light bulb 80 shown in Fig. 1 and Fig. 2 must be installed in a cylindrical shell 81 before it can be used as a lamp.

Due to the continuous advancement of LED technology, the brightness of LED products continues to increase. From the early indicator light function, it has been extended to lighting fixtures and backlights with power saving, environmental protection, long life, and small size. The market scale and growth force are increasing day by day. It is said to be an industry that the world will actively promote in the future. However, only 15-20% of the input power of a high-power LED is converted into light, and the remaining 80-85% is converted into heat; if these heat energy cannot be dissipated to the outside in time, the temperature of the LED grain interface will be too high, which will affect its performance. The wavelength will even lead to problems such as attenuation of luminous efficiency and reduced lifespan. Therefore, the overall heat dissipation of the system will be the key to the quality of product functions.

For example: the LED light bulb 90 shown in Fig. 3, Fig. 4 generally comprises: a casing 91, power driver 92, LED 93, installation seat 94 and optical lens 95 are made of.

At present, for LED light bulbs, whether it is MR16 or E/26/27 bulbs, the most commonly used means of heat dissipation is to use a shell 91 with heat dissipation fins, but this finned heat dissipation shell 91 has insufficient heat dissipation. Good, it is easy to cause the LED to accumulate heat energy and easily fail, reducing the service life.

Furthermore, the existing LED light bulb 90 is the same as the above-mentioned existing halogen lamp 80, and is still installed in the cylindrical shell 81 for use. Therefore, there is still room for improvement in shape and heat dissipation.
