High-efficient LED (light emitting diode) lamp

Abstract

The invention discloses a high-efficient LED (light emitting diode) lamp which mainly comprises an alternating current LED module and a radiating lamp seat, wherein the alternating current LED module is provided with a heat conducting part and an electric connection part; the radiating lamp seat is made of nonmetal which has good thermal diffusivity and is in a porous structure, can be directly molded into a shape of the lamp seat, and is provided with an indented part used for accommodating the alternating current LED module; the heat conducting part of the alternating current LED module is combined with the indented part of the radiating lamp seat; and the electric connection part is connected with an external power source. The high-efficient LED lamp provided by the invention also comprises a heat conducting fin, wherein the heat conducting fin is arranged between the heat conducting part of the LED module and the radiating lamp seat; and when the LED is illuminated, the heat generated by the LED can be conducted promptly by the heat conducting fin, thus the heat on the heat conducting fin can be conducted promptly to the radiating lamp base for radiating. The heat radiating lamp seat in the invention can be directly molded into a shape of a common lamp seat, and has the functions of heat radiating and electrical insulation efficiency; and the high-efficient LED lamp can be used for replacing a known lamp bulb, and can be directly used for replacing a lamp bulb without replacing the light fitting.

Description

technical field [0001] The invention belongs to an LED lamp, especially a high-efficiency LED lamp that not only has excellent heat dissipation and electrical insulation effects, but also has the function of directly replacing a bulb without replacing a lamp. Background technique [0002] At present, LED is the abbreviation of Light Emitting Diode (Light Emitting Diode), which is a solid-state light-emitting element made of semiconductor materials. The principle of luminescence is to convert electrical energy into light, that is, to apply current to the compound semiconductor, and through the combination of electrons and holes, the excess energy will be released in the form of light to achieve the effect of luminescence. It belongs to cold luminescence and has a long life. More than 100,000 hours. The biggest features of LEDs are: no need for warm-up time (Idling Time), fast response, small size, low power consumption, shock resistance, low pollution, suitable for mass prod...

AI Technical Summary

Problems solved by technology

[0003] From the above prior application, it can be seen that most of the known LED heat dissipation adopts metal heat sinks, or combines heat pipes, cooling chips, vapor chambers, heat dissipation fans, etc. to dissipate heat. Complexity, high cost, lack of electrical insulation safety regulations, etc., and because the heat dissipation structure required is non-standard design, special lamps must be designed before use

This is the biggest shortcoming of existing known technology, and this shortcoming has become a difficult problem to be overcome urgently in the industry
