Shade-body external heat conduction and dissipation type full-power LED (Light Emitting Diode) lamp

Abstract

The invention discloses a shade-body external heat conduction and dissipation type full-power LED (Light Emitting Diode) lamp comprising a back shade, a heat collector, an LED light-emitting chip, two end shades, a light-gathering tile, a front shade and a light-transmitting shade, wherein the light-transmitting shade is arranged on the front shade; the back shade and the front shade are glidingly fastened and coordinated and are buckled with the two end shades to constitute a lampshade; the heat collector is arranged on the inner vertical axis of the lampshade; the LED light-emitting chip and the light-gathering tile are optically coordinated and arranged on the heat collector; and a heat conduction fin arranged on the inner wall of the back shade and the heat collector are connected in a heat conductivity way. In the invention, a shade-body self-heat-dissipation structure is provided and the shortcomings that the heat dissipation area is restricted and the heat dissipation requirement of a high-power LED lamp cannot be satisfied in the prior art as a heat dissipation structure is directly arranged on the LED light-emitting chip can be overcome; therefore, the heat dissipation efficiency is greatly enhanced, the space structure of the lamp is compressed, the heat dissipation requirements of the LED lamps of different powers are satisfied and the service life of the LED lamp is effectively prolonged; and by utilizing the angle-adjustable light-gathering tile, the light irradiation range can be effectively expanded and the utilization efficiency of the light can be enhanced. The LED lamp provided by the invention is particularly suitable for a roadway lighting lamp or a ceiling type lighting lamp and is easy to popularize.

Description

technical field [0001] The invention belongs to the technical field of lighting, and further belongs to the technical field of LED lamps, and specifically relates to a cover with a heat conduction structure itself, which effectively simplifies the overall structure of LED core components, reduces processing costs, and prolongs the service life of LED lamps. LED lamps. Background technique [0002] Since the 1990s, the concept of "green lighting" has gradually been accepted by the world. The implementation of my country's "green lighting project" began in 2005 to develop and promote high-efficiency and energy-saving lighting fixtures, to establish an economical and comfortable lighting environment system with low energy consumption, and to save energy. Reducing consumption and reducing environmental pollution has become the consensus of the people. [0003] In recent years, LED has become the product of choice for green light sources. However, due to the small area of ​​LED l...

Problems solved by technology

[0006] The invention makes full use of the advantage of the large heat dissipation area of ​​the lamp cover itself, directly or in combination with heat conduction fins on the lamp cover, and conducts the heat on the LED light-emitting chip to achieve the purpose of efficient heat dissipation through heat conduction, which overcomes the direct heat dissipation of the prior art. The heat dissipation structure on the LED light-emitting chip is limited, and the heat dissipation area cannot meet the heat dissipation requirements of large-function LED lamps.
