Thermostatic control LED thermal module

Abstract

A thermostatic control LED thermal module includes at least one fan, a heat dissipation unit, a sensing unit and a controller. One side of the heat dissipation unit is mated with the fan, while the other side of the heat dissipation unit is attached to an LED unit. The sensing unit is electrically connected to the LED unit for detecting the temperature of the LED unit and generating a sensing signal. The controller is electrically connected to the fan and the sensing unit. According to the received sensing signal, the controller operates and processes to generate a control signal to control rotational speed of the fan so as to achieve an excellent heat dissipation effect.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates generally to a thermostatic control LED thermal module, and more particularly to a thermostatic control LED thermal module having excellent heat dissipation effect.[0003]2. Description of the Related Art[0004]Recently, various green products meeting the requirements of energy saving and carbon reduction have been more and more respected. Following the rapid advance of manufacturing technique of light-emitting diode (hereinafter abbreviated as LED), various LED products have been widely applied in various fields as illumination devices.[0005]When LED emits light, LED also generates high heat. The heat must be efficiently dissipated. Otherwise, the heat will locally accumulate where the light-emitting component is positioned to cause rise of temperature. This will affect the normal operation of some components of the product or even the entire product and shorten the lifetime of the product. ...

AI Technical Summary

Benefits of technology

The present invention provides a thermostatic control LED thermal module with excellent heat dissipation effect. This module is capable of providing a thermostatic effect for LED units, regardless of their powers. It can be used with different LED units and can provide corresponding wind intensity for dissipating heat.

Problems solved by technology

When LED emits light, LED also generates high heat.

This will affect the normal operation of some components of the product or even the entire product and shorten the lifetime of the product.

However, the conventional LED thermal module can hardly provide effective heat dissipation effect.

As a result, in case the LED unit 15 generates very high heat after a long period of operation, the fan 12 can hardly provide sufficient wind intensity to effectively forcedly dissipate the heat of the heat sink 10.

In some more serious cases, the LED unit 15 will even damage (burn out) due to overheating.

Moreover, the conventional fan 12 can only provide constant wind intensity for the LED unit 15.

Therefore, it is impossible to apply the LED thermal module to another LED unit with different luminous power.

According to the above, the conventional LED thermal module has the following shortcomings:1. The conventional LED thermal module has poor heat dissipation effect.2. The conventional LED thermal module cannot provide thermostatic effect for the LED unit.3. It is impossible to apply the conventional LED thermal module to another LED unit with different luminous power.
