Description

Technical Field

[0001] The utility model relates to the technical field of aluminum radiators, in particular to an angle-adjustable radiator. Background Art

[0002] LED generates light through the luminous principle of semiconductor materials. When the current flowing through the LED chip passes through the semiconductor material, it will react with the electrons in the semiconductor material to generate energy. During the operation of the LED, only about 20% of the electrical energy is converted into light energy, while the other 80% is converted into heat. This causes the LED to generate a lot of heat. If the heat cannot be dissipated in time, the temperature of the LED will be too high. Excessive temperature will have a negative impact on the life and stability of the LED. Therefore, in order to ensure the normal operation of the LED and extend its service life, effective heat dissipation measures must be taken, and the heat sink becomes a very important component.

[0003] The existing heat sink for LED is directly installed on the lamp holder, which can dissipate heat in time. However, due to its simple structure and only heat dissipation function, the LED lamp itself cannot achieve adjustable irradiation angle after the radiator is installed, and cannot meet the requirements of different irradiation angles.

[0004] Therefore, it is particularly important to design an angle-adjustable radiator to solve the above-mentioned defects. Utility Model Content
