Description

A LED light source module

technical field

The utility model belongs to the technical field of lighting equipment, in particular to an LED light source module.

Background technique

As global energy becomes increasingly tense, in order to alleviate the energy pressure brought about by economic development, energy-saving and environmental protection functions of products have gradually become people's first choice. Therefore, replacing ordinary lamps with LED lamps has become an unstoppable trend. However, heat dissipation has always been one of the key problems to be solved for LED lamps. Due to the high brightness and high heat generation of LED lamps, poor heat dissipation will directly lead to rapid aging of LED lamps and reduced stability, which not only affects the lighting effect, but also greatly reduces The service life of LED lamps, on the other hand, the replacement of existing ordinary lamps (such as incandescent lamps, metal halide lamps, energy-saving lamps, etc.) Waste of resources.

Utility model content

Aiming at the deficiencies of the prior art, the utility model provides an LED light source module, which does not need to replace the original lampshade, does not change the original lighting structure, and has a good heat dissipation effect, prolonging the service life of the LED light source module.

The technical solution adopted by the utility model is: an LED light source module, including a heat sink and a light source substrate on which LEDs are arranged. The key point is that the heat sink is an inverted bowl-shaped fin heat sink. A heat conductor fixedly connected to the fin radiator is arranged in the bowl belly of the fin radiator, the light source substrate is fixedly connected to the bottom of the heat conductor, and a lead through hole of the light source substrate is arranged in the heat conductor and the fin radiator. The heat conductor is in the shape of an inverted boss, and the waist of the boss is provided with a connecting bracket fixedly connected with the lamp housing.

Preferably, the inside of the finned heat sink is a hollow structure.

Preferably, the heat conductor is an aluminum heat conduction block.

Preferably, the top of the heat conductor is provided with circularly arranged cooling fins.

The beneficial effects of the utility model are: using the heat conductor combined with the fin radiator to ensure that the heat generated by the light source substrate can be guided away faster, the external cold air enters from the lower part of the fin radiator, and the heat in the fin radiator The air generates convection and takes away the heat generated by the light source substrate, which further enhances the heat dissipation effect of the LED light source module. The lighting effect is stable and the power consumption is low. The boss shape is set according to the opening size of the original lamp housing, and the LED light source module is fixed with the original lamp housing by means of the connecting bracket. The structure is simple, easy to operate, saves the need to replace a new lamp housing, saves resources, and conforms to the concept of energy saving and environmental protection.

detailed description

Below in conjunction with accompanying drawing and specific embodiment the utility model is described further.

As shown in Figure 1, the LED light source module includes a heat sink and a light source substrate 1 with LEDs arranged thereon. The external air contact area is large, and it is easy to dissipate heat. A heat conductor 3 fixedly connected to the fin radiator 2 is arranged in the bowl belly of the fin radiator 2. The light source substrate 1 is fixedly connected to the bottom of the heat conductor 3. And the fin heat sink 2 is provided with the lead wire penetration hole 5 of the light source substrate 1, the heat conductor 3 is in the shape of an inverted boss, and the waist 3-1 of the boss is provided with a connecting bracket 4 fixedly connected to the adapted lamp housing 6, The connecting bracket 4 is fixed with the ceiling, the mounting seat and the like, and the connecting bracket 4 is provided with a via hole and is affixed to the waist 3-1 of the boss. The waist 3-1 of the boss is fixed according to the via hole on the connecting bracket 4, which has good adaptability and adjustable performance, and eliminates the need to replace the original adapter lamp housing when replacing an incandescent lamp with an LED light source module 6. The step of connecting the bracket 4 realizes the reuse of old objects, and is easy to install and disassemble, meeting the requirements of environmental protection and energy saving. At the same time, the original installation position is used for installation, without changing the original lighting structure, and the lighting effect is good.

The heat conductor 3 transfers the heat to the fin radiator 2. At this time, the external cold air enters the cooling channel of the fin radiator 2 through the bottom of the fin radiator 3, and conducts hot and cold air convection, so that the heat can be timely and completely effective. The cooling of the LED light source module greatly prevents the problems of aging and poor performance stability caused by the high temperature of the LED light source module, ensures the stable lighting effect of the LED light source module, and greatly prolongs the service life of the LED light source module , which not only reduces power consumption, but also reduces the number of replacements, which meets the concept and requirements of environmental protection and energy saving.

The inside of the fin radiator 2 is a hollow structure, which reduces the overall weight of the light source module and saves materials.

The heat conductor 3 is an aluminum heat conduction block, which is light and cheap, which not only reduces the overall weight of the light source module but also saves the total cost.

The top of the heat conductor 3 is a circularly arranged cooling fin 3-2, which increases the contact area between the heat conductor 3 and the fin radiator 2, and further improves the cooling speed.
