Abstract

LED street light lamp has a disadvantage that the temperature of the lamp is increased due to the heat generated during operation, thereby lowering the efficiency of the lamp. The present invention, in order to compensate for the above disadvantages, the invention of the structure of the heat dissipation module that can lower the temperature of the LED lamp by coupling the heat dissipation module to the case portion of the lamp, and the heat dissipation of connecting a plurality of heat dissipation modules to the body The invention for the combination method and the LED street lamp using the same.

When dissipating a lot of heat from the lamp case, combining the number of heat dissipation modules can reduce the temperature, eliminating the inconvenience of having to manufacture a new heat sink or lamp case according to the lamp capacity whenever the capacity of the lamp changes, The shape of the heat dissipation module can be combined into a flat and curved shape to adjust the divergence angle of the light, thereby solving the problem of divergence angle of the light.

Description

LED Lamp and Street Lamp Using Heatsink Module {LED Lamp and Street Lamp Using Heatsink Module}

Existing inventions related to heat dissipation of LED street lamps have used a method of attaching a fan to the heat sink, a method of widening the contact surface of the heat sink, and a method of attaching and cooling a thermoelectric element to the heat sink. It had many disadvantages in terms of efficiency and cost.

The present invention is an invention for the LED street light lamp that can be modified in the form of a heat sink in the form of a planar heat sink and a curved shape by configuring a heat sink combined heat radiation module.

In the present invention, the temperature of the lamp is increased due to the heat generated during the operation of the LED street light lamp, there is a disadvantage in that the efficiency of the lamp is lowered, and to compensate for this disadvantage in order to lower the temperature of the lamp, heat radiation By using the module, the shape of the heat dissipation module can be combined and transformed into a flat and curved shape so that the light divergence angle can be adjusted.

There are many disadvantages in terms of efficiency and cost.

1. In case of using high output LED lamp or discharge lamp, heat dissipation module is applied to eliminate the disadvantages such as lowering the lamp efficiency and shortening the life due to the temperature increase of the lamp.

2. When fixing the heat dissipation module to the case of the lamp, make sure that the shape of the heat sink is both flat and curved.

3. Adjust the holding temperature by adding or subtracting the number of heat dissipation modules.

1. In case of using high output LED lamp or discharge lamp, various types of heat dissipation module are implemented to eliminate the disadvantages such as lowering lamp efficiency and shortening the lifespan due to temperature increase of the lamp. To maintain the lamp temperature at a constant level.

2. The guide part of the case of the lamp fixing the heat dissipation module is configured to be movable and fixed so that the shape of the heat dissipation plate can be both flat and curved.

3. The output and holding temperature of the lamp can be adjusted by determining how many radiating modules are connected according to the lamp's operating temperature and lamp capacity.

Depending on the output or shape of the lamp, the number of heat dissipation modules to be combined can be controlled to dissipate heat generated from the lamp case to the outside, and when the number of heat dissipation modules is combined, the temperature can be lowered. Each time, the inconvenience of having to manufacture a new heat sink according to the lamp capacity can be reduced.

The shape of the guide part of the case of the lamp which fixes the heat dissipation module is configured to be movable and fixed, so that the heat dissipation plate can be formed in both flat and curved shapes, thereby adjusting the light divergence angle. This is how you can get the light divergence angle you want.
