Problems solved by technology

[0004] But the LED is a photoelectric device, only 15% to 25% of the electric energy is converted into light energy during its working process, and the rest of the electric energy is almost all converted into heat energy, which makes the temperature of the LED rise.

Abstract

The invention relates to an LED lamp cooling component and a production method thereof. The production method comprises the following steps: step (1) of manufacturing the LED lamp cooling component by metals; step (2) of cleaning the LED lamp cooling component at a plurality of times with ultrasonic waves, and drying; and step (3) of plating a la-doped or cerium-doped titanium dioxide film with the thickness of 50-100 mm on the surface of the LED lamp cooling component by using a sol-gel method or a vacuum vapor deposition method. The surface of the LED lamp cooling component processed by the invention is like a form that is macroscopically bright and clean, and microcosmically coarse, thus greatly increasing the contact area between a road lamp cooling component and the outside world, reducing heat shield, significantly improving cooling effects, and also keeping excellent performances such as corresponding corrosion resistance, abrasive resistance and so on. In addition, rare earth element oxides are doped so as to improve actively of the system, and have functions of degrading pollutants, resisting bacteria, sterilizing, resisting fouling and cleaning by self. The film-coated system has no matters and radiation harmful to the human body, so that the LED lamp cooling component is a novel environmental protection energy-saving system, and can be widely applied to surface treatment of the metal LED cooling component.

Description

technical field [0001] The invention belongs to the field of heat dissipation treatment of lamps, and in particular relates to a heat dissipation part of an LED lamp and a surface treatment method for the heat dissipation part of the LED lamp. Background technique [0002] LED (Light Emitting Diode, called light emitting diode), is a solid-state light source. The application of LEDs has a long history. It was mainly used in the fields of indicator lights of various electronic equipment, large-screen displays, signal lights and LCD screen backlights. In recent years, with the progress of crystal growth process technology and nanotechnology of GaP and GaN series III-V compound semiconductors, the light efficiency and high-power integration technology of LED have been greatly improved, and LED has begun to be used in the field of lighting. In the initial application, there have been many lighting fixtures with high-power LEDs as light sources, such as LED street lights, LED mi...
