LED (Light-Emitting Diode) illuminating lamp

Abstract

The invention discloses an LED (Light-Emitting Diode) illuminating lamp comprising a lamp holder, a control circuit board, a lamp shade and a heat radiating mechanism; the control circuit board is welded and fixed with a plurality of LED lamp wicks; the lamp shade covers above the LED lamp wicks; the heat radiating mechanism comprises a heat radiating substrate and a heat conducting seat, wherein the heat radiating substrate is arranged between the lamp holder and the lamp shade and is provided with a cavity in the center, and the heat conducting seat is arranged in the cavity of the heat radiating substrate and is fixedly connected with the lower surface of the control circuit board; the heat radiating substrate comprises a plurality of heat radiating fins radiating outwards, and the cross-section area of the heat radiating substrate is reduced progressively from the middle to the two ends; and the periphery of the heat conducting seat is in tight press fit with the inner wall of the heat radiating substrate. By adopting the LED illuminating lamp, the heat radiating effect can be better, the ageing of the LED lamp wicks can be better prevented, and the illuminating range is wider.

Description

Technical field [0001] The invention involves a LED lighting. [0002] Background technique [0003] LED is the light -emitting diode. Due to its small volume, low power consumption, long service life, environmental protection, etc., it has been widely used in various fields such as lighting and large screens.With the continuous improvement of LED power, the heat generated by it continues to increase. If it cannot be solved, it will cause the aging of the component and shorten the service life.LED lights in the current technology, such as Figure 5 It is shown in it, including lamp head 1, lampshade 5, LED lamp core set in the lampshade (not displayed in the picture), and the heat dissipation mechanism between Lantern 1 and Lantern 5. Among them [0004] The heat dissipation matrix of the heat dissipation mechanism 6 is anode aluminum oxide (aluminum -based aluminum -based aluminum layer). Due to the aluminum aluminum alumina, the heat conduction effect is reduced, so that the hea...

AI Technical Summary

Problems solved by technology

[0004] The heat dissipation substrate 6 of the heat dissipation mechanism is mostly anodized aluminum material (aluminum material with a thin layer of aluminum oxide formed on the surface), because the surface of the aluminum material is covered with aluminum oxide, resulting in a heat conduction effect Reduced, so that the heat generated by the LED wick cannot be released quickly, thus affecting the service life of the LED lamp

Moreover, the heat dissipation base 6 of this kind of LED lamp is in the shape of a cylinder. On the one hand, the volume of the entire lamp is relatively large;
