Problems solved by technology

In the patent, since the lamp cap and the lampshade are directly connected, after the LED is fixed on the radiator, the accommodation space between the LED and the lamp cap is limited, and it is difficult to dissipate heat for high-power LEDs, such as expanding the heat dissipation area, etc., and cannot accommodate Cross-current circuit or driving power, etc., directly affect the service life and application range of the lamp

Embodiment Construction

[0025] Such as figure 1 As shown, the appearance of this embodiment 1 is a traditional lamp, and the visible parts include a lamp base 1, an insulating member 2, a reflector 5, a high-power LED 4, a lampshade 6, and the like. In the figure, the lamp holder 1 adopts various standard thread structures, which is convenient to install and use, and can directly replace the existing lamp. The insulator 2 is connected to the lamp cap 1 and is made of insulating materials such as plastics and ceramics, and is electrically isolated from components below the lamp cap 1 . Evenly distributed on the surface of the insulator 2 are rectangular heat dissipation holes 21, the size, quantity and shape of which can be designed according to the specific use to increase the air convection of the heat sink inside the insulator 2 and the reflector 5 to strengthen heat dissipation. The lampshade 6 is made of materials such as transparent glass or acrylic, and has structures such as a reflector 5 and...

Abstract

The invention discloses a high power LED lamp comprising a high power LED, a lamp cap and a heat radiator. The high power LED is fixed on the heat radiator which is positioned in an empty cavity formed between an insulator and a reflecting shade. The invention has good internal structure, remarkable heat radiation efficiency, scientific optical treatment, low production cost, simple installation and attractive appearance.

Description

technical field [0001] The invention relates to a lighting lamp, in particular to a lamp using a high-power LED as a light source. Background technique [0002] At present, the market is mainly dominated by low-power LED lights, and there are still few high-power LED lights. However, compared with low-power LED lights, high-power LED lights have many inherent advantages due to packaging materials and process problems, such as service life and light source consistency. With the continuous improvement of high-power LED luminous efficiency and cost In the future, high-power LED lights will replace low-power LED lights and become the mainstream of the market. [0003] The low-power LED light is a combination of multiple low-power LEDs in series and parallel, and is directly fixed on the PCB circuit board through two pins. Because the LED power is very low, no special heat dissipation design is required, and the cost of low-power LEDs is very low. Designed to be simple to use. ...
