Embodiment

[0045] see figure 1 , which is an implementation example diagram of a lamp. It includes an LED lighting unit. The LED lighting device includes a main beam 2 , an LED light source module 1 , and a power supply 3 . in,

[0046] The main girder 2 can be formed as a radiator by extruding and stretching a profile with better heat dissipation effect. For example, a metal profile with light weight and good heat transfer (such as aluminum, copper, or an alloy with good heat dissipation or strength) is selected to be formed by extrusion and stretching, which can be in the shape of a U-shaped cavity. The main girder 2 can be a U-shaped cavity structure that is completely closed, or a U-shaped cavity structure that is not completely closed. For the convenience of subsequent description, in the U-shaped cavity structure of the main beam 2, the bottom of the cavity is called the bottom of the main beam 2, the two walls of the U shape are called the sides of the main beam, and the other...

Abstract

The invention discloses an LED (light emitting diode) illumination device which comprises a girder, a plurality of LED light source modules and a power supply, wherein the power supply provides electric power for the LED light source modules which can be detachably arranged at at least one side of the girder; the girder is a sectional material with a better heat radiation effect and forms a heat radiation body through extruding and extending into a whole, and is of a U-shaped cavity shape; the inner side wall below the girder is of an inverted-ladder-shaped wedge slot structure; the outer side wall of the shell of the power supply is also of an inverted-ladder-shaped wedge slot structure; the power supply can be inserted in or extracted out of the girder, and when the power supply is inserted into the girder, the wedge slot structure of the power supply is fit with that of the girder. The girder can be utilized for finishing the heat radiation efficacy for the design, and also the tight adhesive design of the bottom of a power supply box and the bottom of the girder reaches a favorable heat radiation effect simultaneously.

Description

technical field [0001] The invention relates to an LED lighting device, in particular to an LED lighting device with a very good heat dissipation effect. Background technique [0002] At present, with the development trend of energy saving and emission reduction, LED (Light Emitting Diode, Light Emitting Diode) is more and more widely used due to its energy saving, environmental protection, high luminous efficiency, and long life. , with high luminous efficiency, it is regarded as a cold light source, and it has a tendency to replace traditional incandescent and fluorescent lamps. [0003] For this reason, among the existing street lights / tunnel lights, LED street lights / tunnel lights have become a follow-up development trend. LED street lights / tunnel lights are mainly composed of internal illuminants and external lamp housings. And there is a fixed structure on the lamp housing, which is used to connect with the light pole of the street lamp or be fixed on the tunnel wall...
