LED bulb having excellent ventilating and heat dissipation functions

Abstract

The invention relates to an LED bulb having excellent ventilating and heat dissipation functions. A main body comprises a lamp holder and a glass blister; a miniature air outlet, electrical contacts and an LED power supply driving assembly are arranged on the lamp holder; a glass core column pipe, an electric light-emitting assembly and an exhausting pipe are arranged in the glass blister; the glass core column pipe is in a deep and long cylinder shape; a cylinder bottom comprises a core column head where a charging and exhausting hole is formed; the exhausting pipe is arranged in the center of a cylinder cavity; and a circular cavity around the exhausting pipe forms an electric light-emitting assembly accommodating cavity communicating with outside air. The electric light-emitting assembly contains heat absorbing and conducting blocks, part of heat and liquids produced during working are left in the environment where the outside natural air circulates and are immediately diffused and evaporated, the heat dissipation pressure of the inner cavity of the blister is reduced, meanwhile, the corrosion influence of liquid residues on an LED light-emitting element is avoided, the service life and the illumination effect of the LED bulb can be guaranteed, and the LED bulb is simple and reasonable in structure, reliable in working, long in service life and low in production and daily use costs and has the very high practicability.

Description

technical field [0001] The invention relates to the technical field of lighting fixtures and lamp decoration manufacturing, in particular to an LED light bulb with excellent ventilation and heat dissipation functions. Background technique [0002] With the development of modern lighting technology, incandescent lamps, which have been popular for more than a hundred years, are being replaced by LED lamps that are recognized by the world as having significant energy-saving effects. figure 1 Shown is developed on the basis of the basic structure of incandescent lamps, such as figure 2 Shown is an LED strip light bulb with a traditional glass bulb. exist figure 1 Among them, the main body of a traditional incandescent bulb is composed of a lamp cap 1 and a glass bulb 2 bonded together with cement. Wherein: the lamp cap 1 is provided with a miniature air outlet 11, and an electrical contact 13 at one end of the conductive guide wire A 12 is welded inside; the glass bulb 2 cav...

AI Technical Summary

Problems solved by technology

In addition, because the liquid residue generated by the LED light bar during the working process stays in the closed cavity of the bulb shell because there is nowhere to volatilize and accumulate thicker, it will inevitably lead to corrosion of the LED light bar, thereby affecting the luminous efficiency and working life of the bulb, which leads to In the production process of LED light strips, high-cost raw materials and corresponding processing techniques must be used to minimize liquid residues

Therefore, there are many disadvantages such as complex structure and high production cost on the whole, which are not ideal from the perspective of economy and practicability.
