Problems solved by technology

However, in the follow-up research, it was found that due to the diffuse reflection effect of the optical diffusion cover, the back of the light source also became brighter, and this part of the light was wasted, which affected the optimal illumination effect of the lamp.
[0003] In addition, in order to solve the heat dissipation problem of LED lamps, it is generally used to paste the aluminum substrate on the aluminum alloy heat sink to improve the heat dissipation efficiency. This structure results in heavy weight and high cost of the lamp.

Embodiment 1

[0042] refer to Figure 1 to Figure 3As shown, an LED surface light source spotlight that is easy to dissipate heat in the present invention includes an aluminum substrate 1 on which a number of LED lamp beads 2 are distributed. It is characterized in that the aluminum substrate 1 is connected with The mounting frame 4; the mounting frame 4 is composed of a mounting plate 4a and at least two connecting plates 4b arranged at intervals along the length direction on the mounting plate 4a, and the connecting plates 4b are hinged to the connector 3. In order to improve the strength of the connecting plate, several reinforcing ribs 4h are arranged on the back of the connecting plate 4b along the length and width directions. The reinforcing ribs are formed directly on the back of the connecting plate by stamping technology.

[0043] In this embodiment, the connecting piece 3 is a connecting rotating bracket corresponding to the connecting plate 4b one by one, and the connecting rota...

Embodiment 2

[0047] refer to Figure 4 and Figure 5 As shown, the structure of an easily heat-dissipating LED surface light source spotlight of the present invention is basically the same as that of Embodiment 1, the difference is that a connection hole adapted to the outer diameter of the connection inner sleeve 3b is provided on the connection plate 4b 4c. At the same time, a reflective sleeve 11 is provided on the inner surface of the light guide portion 6f. Its mode of use is the same as in Example 1.

Embodiment 3

[0049] refer to Figure 6 As shown, the structure of the easy-to-dissipate LED surface light source spotlight of the present invention is basically the same as that of Embodiment 2, the difference is that the connector 3 is an aluminum alloy heat sink, and an aluminum The installation plane compatible with the base plate 1 is provided with a rotating shaft hole 3g on both sides of the aluminum alloy radiator, and a connecting ring 4d matching the rotating shaft hole 3g is provided on the connecting plate 4b, and the connection on both sides of the connecting ring 4d Two arc-shaped adjusting long holes 4e are arranged symmetrically on the plate 4b, and second screw holes 3h are respectively provided on the aluminum alloy radiators corresponding to the two arc-shaped adjusting long holes 4e, and the adjusting screws pass through the arc-shaped adjusting long holes 4e It is threadedly connected with the second screw hole 4h. This structure with aluminum alloy heat sink is suitab...

Abstract

The invention discloses an LED surface light source spotlight easy to cool, and belongs to the technical field of LED lights. The LED surface light source spotlight is characterized by comprising an aluminum substrate, several LED lamp beads are distributed on the aluminum substrate, and a mounting frame is connected to the aluminum substrate through a connecting part; the mounting frame is composed of a mounting plate and at least two connecting plates arranged on the mounting plate in the length direction in a spaced mode, and the connecting plates are hinged to the connecting part. The invention aims at providing the LED surface light source spotlight which is compact and novel in structure, good in cooling effect, long in service life and easy to cool, and the LED surface light source spotlight is used for outdoor illumination and advertisement illumination.

Description

technical field [0001] The invention relates to an LED lamp, more specifically, to an LED surface light source spotlight which is easy to dissipate heat. Background technique [0002] As a new type of lighting source, LED energy-saving lamps have been favored by the people and strongly supported by the country for their remarkable characteristics of energy saving, health, environmental protection and long life. In the actual use of LED lights, two common problems of heat dissipation and glare must be solved. If the heat dissipation is not good, the life of the wick will be greatly shortened. If the glare is not handled well, it not only affects the lighting effect, but also is harmful to the human eye. In the early stage, after applying for the self-developed optical diffusion cover, the glare problem was effectively solved, and the lighting effect was further improved. However, in follow-up research, it was found that due to the diffuse reflection effect of the optical di...
