Embodiment 1

[0048] This embodiment discloses a heat dissipation device for LED street lamps, such as Figure 4 As shown, the LED street lamp cooling device includes a light source mounting plate 22, the first surface 221 of the light source mounting plate 22 is used to install the LED light source; and a plurality of detachable cooling fins arranged on the second surface 222 of the light source mounting plate 22 Each fin unit 21 includes a plurality of fins 211 .

[0049] It should be noted that, for the convenience of description, in the present invention, the first surface on which the LED light source is installed on the light source mounting board is defined as the front of the light source mounting board, and the second surface on the light source mounting board used to install the heat dissipation fin unit is also defined as That is, the surface opposite to the front of the light source mounting plate is defined as the back of the light source mounting plate. The front and back of t...

Embodiment 2

[0060] In this embodiment, a LED street light source module is provided, such as Figure 8 As shown, it includes an LED light source 33, a reflector 34, a lampshade 35, a lampshade pressure frame 36 and a heat dissipation device, wherein the heat dissipation device includes a light source mounting plate 32 and a plurality of detachable heat dissipation fins located on the back of the light source mounting plate Unit 31.

[0061] The LED light source 33, the reflector 34, the lampshade 35, and the lampshade pressure frame 36 are located on the front of the light source installation board, and are fixed on the front of the light source installation board by screws or heat-conducting silica gel. The reflector 34 is used to reflect the outgoing light that deviates from the central axis of the light source module to the vicinity of the central axis of the light source module to increase the concentrated irradiation effect of the outgoing light; the lampshade 35 and the lampshade pr...

Embodiment 3

Abstract

The invention provides an LED street lamp light source module, a manufacturing method of the LED street lamp light source module and a cooling device of the LED street lamp light source module. The cooling device of the LED street lamp light source module comprises a light source installation board and a plurality of detachable cooling fins arranged on the second surface, opposite to the first surface, of the light source installation board, wherein the first surface of the light source installation board is used for installation of LED light sources. Due to the fact that the cooling fins can be assembled on the light source installation board and can be disassembled from the light source installation board, the cooling capacity of the LED street lamp light source module can be adjusted through the adjustment of the number of the cooling fins installed on the light source installation board according to the power of the LED street lamp light source module, the overall size of the LED street lamp light source module does not need to be adjusted, and therefore the cost for adjusting the heat-dissipation capacity of the LED street lamp light source module is reduced. According to the LED street lamp light source module and the manufacturing method of the LED street lamp light source module, due to the adoption of the cooling device, the cost for adjusting the cooling capacity of the LED street lamp light source module can be reduced as well.

Description

technical field [0001] The invention relates to the field of road lighting, and more specifically relates to an LED street light source module, a manufacturing method thereof, and a heat dissipation device. Background technique [0002] LED (light-emitting diode) street lights are an important part of urban lighting. Traditional street lights using high-pressure sodium lamps as light sources have gradually been replaced by more efficient, safe, energy-saving, and environmentally friendly LED street lights. The LED street lamp radiator is a crucial part of the LED street lamp structure, which directly affects the life of the LED street lamp and the level of light decay. [0003] During the driving process of LED street lamps, less than 30% of the energy is converted into light energy, and most of the energy is converted into heat energy. If the heat dissipation problem of LED street lamps is not well resolved, it will lead to the breakdown of the P-N junction in the light emi...
