Embodiment Construction

[0023] The structural technical scheme of the present invention is further described below in conjunction with embodiment accompanying drawing:

[0024] see figure 1 , 2 , figure 1 It is the basic structure of the technical solution of the high-power LED lighting fixture of the present invention. The high-power LED lighting fixture of the present invention is mainly composed of a heat conducting sheet 17, an LED integrated chip 16 and its driving device. The driving device includes a driving assembly 14 and a vulnerable element 18. 16 heat conduction devices on the chip, the upper part of the heat conduction sheet 17 is provided with a heat sink group together with the heat conduction sheet 17 and the LED integrated chip 16 to be fixed in the middle hole of the supporting plate seat 13, and the upper part of the heat conduction sheet has two "" shaped cover-shaped long The narrow and small air duct takes into account the heat preservation and protection of the double body...

Abstract

The problems of an existing high-power LED illumination lamp and chip heat radiation are the technical key point, if the heat radiation is poor, the LED service life is directly influenced, the light failure is accelerated, and the LED lamp service life is shortened, so that the upper portion of an LED lamp is provided with a large aluminum alloy die-casting heat radiation sheet. A high-power LED illumination lamp mainly consists of a heat-conducting piece (10) and an LED lamp (11). A conventional heat radiation technology is overturned, and the super-high temperature difference of a tornado in the meteorology is utilized to produce the rotating and rotating-superimposing effects in the tornado by adopting a man-made method, so that the air flowing speed is greatly accelerated only by giving slight initiative convection flows, good heat radiation effect is achieved, the high-power LED illumination lamp is good in quality and competitive in price, a built-in drive enables replacement of indoor and outdoor illumination lamps to be very simple, easy and convenient like common lamp replacement, the built-in drive and the lamp are alternatively combined through intelligent control, energy is saved, the structure and the LED service life are prolonged, and a method is ingenious, simple and scientific.

Description

technical field [0001] The present invention relates to lighting devices. Background technique [0002] In the previous high-power LED lighting fixtures, the heat dissipation of the chip is the focus of its technical problems. If the heat dissipation is not good, it will directly affect the life of the LED. If it is light, it will accelerate the light decay and shorten the life of the LED lamp, and if it is serious, it will burn the chip and the LED bulb. Therefore, there is a large aluminum alloy die-casting heat sink (device) on the upper part of the LED lamp, which uses air convection to reduce the working temperature. The larger the power of the LED, the larger the heat dissipation "hat". Therefore, the heat dissipation of the heat sink at the bottom of the chip depends on whether the area of ​​the heat sink is large enough. It is a standard configuration to mount a bulky heat dissipation "hat" on the LED street lamp. When the lamp is on, the temperature of the surround...
