Abrégé

The present invention discloses a lens oil and mist prevention device, including an optical lens and a layered thermal insulation assembly, wherein the layered thermal insulation assembly includes a layered thermal insulation disk and thermal insulation glass; and the thermal insulation glass is fixed in the layered thermal insulation disk in a layered interval arrangement in a light emerging direction, and the optical lens is disposed in a direction of a front end of the thermal insulation glass. In the present invention, natural generation and accumulation of oil stain and water mist in a lamp are eliminated from the source by means of a way that heat balance is achieved inside and outside the lens and the temperature difference is reduced, while designing a multi-layer thermal insulation zone as needed to gradually lower the temperature, and the oil and mist prevention effect is significantly better.

Abrégé

An oil and water mist prevention device for a lens. The oil and water mist prevention device comprises an optical lens (10) and a layered heat insulation assembly (20), wherein the layered heat insulation assembly (20) comprises a layered heat insulation disk (21) and a plurality of sheets of heat insulation glass (22), the sheets of heat insulation glass (22) being fixed inside the layered heat insulation disc (21) in a layered and spaced-apart arrangement in the direction of light emission; and the optical lens (10) is disposed in front of the sheets of heat insulation glass (22), such that a light beam from a lamp reaches the optical lens (10) after sequentially passing through a plurality of stages of separate heat insulation temperature zones. Compared with the prior art, by means of a method for achieving thermal equilibrium and reducing the temperature difference on the inner and outer sides of the lens, and by designing multiple layers of heat insulation zones as needed to achieve step-by-step cooling, the natural formation and accumulation of oil stains and water mist in the lamp are fundamentally prevented. Moreover, there is no need to frequently and periodically purge gas from the lamp, thereby saving on maintenance costs of the stage lamp. In addition, the costs of lamp fittings are saved, and the internal structure of the stage lamp can be made more compact, lightweight and miniaturized.

Abrégé

Disclosed in the present invention is a waterproof stage lamp structure convenient for disassembly, assembly and maintenance. An upper shell, a waterproof heat conductive plate, and a lower shell are detachably connected to one another by means of anti-loosening connecting pieces; a lens assembly comprises a shell and a lens; the shell and the upper shell are detachably connected to each other; the lens is arranged at a light outlet on the shell; a main body functional module is electrically signaled to a front end functional module and a heat dissipation module by means of connecting pieces, separately; the main body functional module and the heat dissipation module are separately matched with a guide positioning rod so that the central axes of central light holes of the modules are concentric. Also disclosed in the present invention is a waterproof stage lamp. The present invention can ensure tight connection between each module power supply and a signal interface and rapid mounting and maintenance inside the lamp, and can also ensure concentricity of the central axes of the central light holes of the modules and automatic connection and separation between the power supply and the signal interface during disassembly and assembly.
