Problems solved by technology

However, the coating formed by anodic oxidation film treatment (aluminum oxide film treatment) does not pass infrared heat radiation sufficiently, and when using a long-life light source such as LED, it may not be able to withstand long-term use and cause the coating to dissipate heat. The problem of device stripping

Abstract

Disclosed is an illuminating apparatus, which is provided with a heat dissipating section wherein heat dissipation is improved by improving heat radiation by infrared rays, and the heat dissipation is maintained for a long period of time. The illuminating apparatus has a heat source, such as a light source and a power supply section, and a heat dissipating section (3) which dissipates heat generated by the heat source, and the illuminating apparatus has a first heat dissipating film (91) on the surface of the heat dissipating section (3), said heat dissipating film (91) being formed by applying a coating material containing a heat dissipating material, then by hardening the coating material. Since the first heat dissipating film (91) is formed by hardening the coating material containing the heat dissipating material, compared with a heat dissipating film formed by anodic oxide coating (alumite treatment), the heat radiation by infrared rays is improved, and the heat dissipation is improved, and furthermore, the heat dissipating film is not easily damaged, and the heat dissipation with the heat radiation can be maintained for a long period of time.

Description

technical field [0001] The present invention relates to a lighting device having a heat dissipation unit that dissipates heat from heat sources such as a light source and a power supply unit. Background technique [0002] Generally, heat-generating components (heat sources) such as light sources and power supply circuit components are housed inside the lighting device. In order to ensure the performance of the heat-generating parts housed inside, it is necessary to suppress the temperature rise of the heat-generating parts, and from the perspective of ensuring safety, it is necessary to suppress The temperature of the outer surface of the lighting device rises. In particular, in lighting devices that use light-emitting diodes (hereinafter referred to as LEDs) as light sources, since the temperature of the LEDs increases, the life characteristics of the LEDs deteriorate, and the luminous efficiency decreases, making it difficult to ensure the necessary amount of light. Theref...
