Description

Radiator fin

Technical Field

The utility model relates to a lamps and lanterns radiator technical field especially relates to a radiator heat dissipation fin.

Background

Lighting is an important requirement of human society, and various lighting technologies such as tungsten filament bulbs, fluorescent lamps, halogen lamps, fluorescent lamps, cold cathode fluorescent lamps, LEDs, etc. can provide light sources to meet the lighting requirements.

Different light-emitting modes, which have light-emitting characteristics and efficiency, can meet different requirements, wherein for the LED, the LED has extremely high energy conversion efficiency, can effectively use energy, and has been gradually and widely applied to various lighting devices under the condition of high energy rise so as to meet the requirements of energy saving and carbon saving.

Although LEDs have the characteristics of low power consumption and energy saving, a relatively large number of LEDs are generally required to meet the requirement of illumination in practical use. When a certain number of LEDs are assembled, the generated heat is accumulated to form a high temperature environment, and the LEDs emit light under the high temperature environment for a long time, and the lifetime thereof is greatly reduced, which leads to a lifetime inferior to the expected lifetime, so that the environment can not meet the actual use requirement when the environment needs high illumination.

The existing heat dissipation mode of the LED lamp is mainly to add a fan to forcibly dissipate heat, but the mode has low reliability, a heat dissipation system is complex, a small amount of LED lamp radiators are also provided, and the radiators generally comprise heat conduction columns and heat dissipation fins, but the heat dissipation fins have complex structures and poor heat conduction effects.

Therefore, there is a need for a new heat sink fin to overcome the above problems.
