Embodiment

[0020] Such as figure 1 As shown in the figure, an LED light source module used in outdoor lamps includes a lens 1, a sealing ring 2, a light source assembly 3, a radiator 4 and a waterproof joint 5 connected sequentially from top to bottom, and the edge of the lens 1 is provided with a groove 107, a sealing ring 2 is provided in the groove 107, no less than one heat dissipation fin 401 is provided at the bottom of the radiator 4, and a waterproof joint 5 is connected, and the electrical connection line 6 passes through the waterproof joint 5 and the light source assembly 3 connected. By increasing the number of heat dissipation fins 401 to increase the heat dissipation surface area, the heat generated by the LED lamp bead can be quickly dissipated into the air to effectively reduce light decay.

[0021] Such as Figure 5 As shown, the cross-sectional shape of the sealing ring 2 is H-shaped, and the middle part extends to both sides, and is placed in the groove 107 reserved ...

Abstract

The invention discloses an LED light source module used for an outdoor lamp. The LED light source module comprises a lens, a sealing ring, a light source module, a radiator, a waterproof connector and an electrical connecting wire. The lower end of the light source module is connected with the radiator, the upper end of the light source module is connected with the lens, a groove is formed in the edge of the lens, the sealing ring is arranged in the groove, not less than one cooling fin is arranged at the bottom of the radiator and connected with the waterproof connector and the electrical connecting wire, and the electrical connecting wire penetrates through the waterproof connector to be connected with the light source module. By the adoption of the LED light source module used for the outdoor lamp, the heat radiation superficial area is increased by increasing the number of the cooling fins, so that heat generated when LED lamp beads work is quickly radiated to air, and luminous decay is effectively reduced; the sealing ring is arranged in the groove, waterproofness can be effectively achieved, good heat radiation, protection and light distribution can be integrated, the assembling process is simple, and the LED light source module is suitable for large-batch production.

Description

technical field [0001] The invention relates to the field of LED lamp lighting, in particular to an LED light source module used in outdoor lamps. Background technique [0002] With the improvement of LED chip technology level, LED, a green energy-saving, low-carbon and environmentally friendly new light source, has been more and more used in the field of lighting, especially outdoor road lighting. The advantages of light source modules, such as convenient maintenance, free power combination, and integration of protection, light distribution, and heat dissipation, are bound to be the development direction of LED outdoor lighting in the future. However, the LED light source modules on the market have the following disadvantages: the heat dissipation effect is poor, so that the temperature generated by the LED cannot be exported, and the light decay is serious; the back of the light source module needs to be coated with heat-conducting materials, and the production process is ...
