Embodiment Construction
[0019] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0020] refer to figure 1 , is a three-dimensional structural schematic diagram of a reflector with heat dissipation function provided by the present invention, which will now be described. The reflector with heat dissipation function includes a reflector base, the reflector base has a reflective surface 1 on the inner surface and a non-reflective surface 2 on the outer surface, the non-reflective surface 2 has a heat radiation layer, The heat radiation layer is formed by placing the base of the reflector as the anode in the electrolyte solution, using electrolysis...

The invention is applicable in lighting field and provides a reflector with a radiating function. The reflector comprises a reflector base body which is provided with a reflecting surface arranged at the inner surface and a non-reflecting surface arranged at the outer surface; the non-reflecting surface is provided with a heat radiating layer which is formed in the following way that: the reflector base body is taken as a positive electrode and is disposed in an electrolyte solution, and under the electrolytic action, an aluminium oxide film is formed on the non-reflecting surface of the reflector; and at the same time, black color coating treatment is conducted to the surface of the aluminium oxide film. The thickness of the aluminium oxide film is 5 micrometers to 30 micrometers. Compared with the conventional reflectors, the reflector provided by the invention has the advantages that: blackness enhancing treatment is conducted to the non-reflecting surface of the reflector, so the heat radiating ability of the surface of the reflector is greatly improved and radiating and cooling abilities of the reflector are effectively enhanced. The invention further provides a lamp provided with the reflector. The lamp adopts the reflector which not only has the function of reflecting rays but also is good in radiating performance, so the lamp has higher reliability and the service life of a light emitting part of the lamp is longer.
Description
technical field [0001] The invention belongs to the field of lighting, and more specifically relates to a reflector with heat dissipation function and a lamp with the reflector. Background technique [0002] Among electronic and electrical products, components often fail due to high temperature, which affects the normal use of the product. High-power lamps are a typical example. When high-power lamps are working, they will generate a lot of heat, which will cause the temperature of the luminous parts to be too high and cause the solder joints at the lamp cap to melt, resulting in damage to the luminous parts and making them unable to work. At present, the high-power lamps on the market dissipate heat by increasing the ventilation holes of the lamp shell and enhancing heat conduction, and these effects can achieve a good heat dissipation effect. Generally speaking, a reflector is used in high-power lamps to protect the peripheral parts of the luminous parts. How to improve t...
