Problems solved by technology

[0002] Explosion-proof and explosion-proof lighting high-power lamps generate high heat during operation and negative pressure inside. When encountering rain or snowflakes, water vapor will be sucked into the light source cavity of the lamp through the sealed structure and adsorbed on the inner wall to form water droplets. , causing the lamps to be not waterproof, affecting the performance of the lamps, thereby reducing the service life of explosion-proof and explosion-proof lighting lamps

Embodiment approach

[0025] Further, see figure 2 and image 3 , as an embodiment of the heat dissipation structure provided by the present invention, the electrical appliance fixing plate 3 is connected to the lower shell 2, and the second sealing member 5 is arranged on the electrical appliance fixing plate 3 and the lower shell 2 of the connection. The electrical appliance fixing plate 3 can also be connected with the upper shell 1, but it is not as convenient as being connected with the lower shell 2. At the same time, the electrical appliance fixing plate 3 is connected to the lower shell 2. When the upper shell 1 is opened, the The electrical components are directly exposed outside, which facilitates the maintenance of electrical components. Since the connection between the electrical appliance fixing plate 3 and the lower case 2 uses bolts, there will be a gap at the connection, so that the heat in the light source cavity 20 will spread to the electrical appliance cavity 10, so a second ...

specific Embodiment approach

[0032] Further, see image 3 , as a specific implementation of the lamp provided by the present invention, a light source fixing seat 210 is provided inside the lower case 2, and the light source fixing seat 210 is assembled in direct contact with the lower case 2 in a large area. 200 is disposed on the light source fixing seat 210 . In this way, the heat generated by the light source part 200 can be transferred to the light source fixing seat 210 through the most effective heat conduction method, and then transferred to the lower case 2 and dissipated, so that the heat dissipation efficiency is improved.

[0033] Further, see figure 1 and image 3 , as a specific embodiment of the lamp provided by the present invention, a transparent member 400 for protecting the light source part 200 is also provided under the lower case 2 . The transparent member 400 can prevent foreign objects from directly contacting the light source part 200 from being damaged, and at the same time, it ...

Abstract

The invention relates to a light fixture. An explosive-proof respiratory device is disposed on a lower housing of the light fixture. A dustproof water-absorbing layer and an explosive-proof layer are disposed in a housing of the explosive-proof respiratory device, and an air pipe is disposed in the explosive-proof layer. On the one hand the dustproof water-absorbing layer can effectively separate dust and absorb water, and on the other hand the explosive-proof respiratory device can realize ventilation through the air pipe and balance the internal and external air pressure of the illumination light fixture to prevent water from being sucked into an electrical cavity of the light fixture in the presence of water. Thus the light fixture with the explosive-proof respiratory device can effectively solve the problem that the water is sucked into the light fixture owing to the negative pressure generated therein.

Description

technical field [0001] The invention relates to the technical field of lighting, in particular to a lamp. Background technique [0002] Explosion-proof and explosion-proof lighting high-power lamps generate high heat during operation and negative pressure inside. When encountering rain or snowflakes, water vapor will be sucked into the light source cavity of the lamp through the sealed structure and adsorbed on the inner wall to form water droplets. , causing the lamps to be not waterproof, affecting the performance of the lamps, thereby reducing the service life of the explosion-proof and explosion-proof lighting lamps. Contents of the invention [0003] Based on this, it is necessary to provide a lamp, which can effectively prevent water from seeping into the light source cavity of the lamp. [0004] A lamp, comprising a lamp housing, a light source component, a ballast and an explosion-proof breathing device. The lamp housing includes an upper housing, a lower housing ...
