LED illuminating lamp with height-adjustable function

Abstract

The invention discloses an LED illuminating lamp with a height-adjustable function. The LED illuminating lamp comprises a lamp seat, a lamp rod and a lampshade. The lampshade and the lamp rod are fixedly connected; an LED lamp bead is fixedly arranged in the position, in the lampshade, on the lamp rod; radiating fins are attached to the top in the lampshade and are in flat shapes; each radiating fin comprises a central fin body in a circular slice shape; a plurality of branch fin bodies are uniformly and fixedly connected to each central fin body; and a plurality of pointed radiating teeth are fixedly arranged on each branch fin body. When the LED lamp bead works, numerous heat is generated, and the heat is effectively radiated under the effect of the radiating fins, so that the working life of the LED lamp bead is prolonged; the branch fin bodies are arranged on the central fin bodies, and the pointed radiating teeth are arranged on the branch fin bodies, so that the radiating area is increased effectively, and the radiating effect is greatly promoted; and the height of the lampshade can be conveniently adjusted through an arranged adjusting device, so that the illuminating range is changed.

Description

technical field [0001] The invention relates to an LED lighting lamp, in particular to an LED lighting lamp with a height-adjustable function. Background technique [0002] LED (light-emitting diode) lighting is a lighting fixture made of the fourth-generation green light source LED. LED is called the fourth-generation lighting source or green light source. It has the characteristics of energy saving, environmental protection, long life, and small size. It can be widely used in various indications, displays, decorations, backlights, general lighting and urban night scenes. High energy saving: saving energy and pollution-free is environmental protection. DC drive, ultra-low power consumption (single tube 0.03-0.06 watts), electro-optical power conversion is close to 100%, and the same lighting effect can save more than 80% energy than traditional light sources. [0003] LED lighting has the following advantages: [0004] 1. Long life: LED light source is called longevity l...

AI Technical Summary

Problems solved by technology

[0008] LED lighting will generate a lot of heat when it is working. If this part of the heat has been accumulated in the lampshade and cannot be dissipated, it will cause the working environment of the LED lamp to overheat, which will lead to accelerated aging of the lamp and reduced working life; In addition, When LED lights are used as bedside lamps or desk lamps, because the overall height of the existing bedside lamps or desk lamps is relatively large, their lighting range is also small. For ceiling lights, it is necessary to increase the height of the LED lighting to expand the lighting range
