Anti-dazzle diffuser plate described in the utility model is anti-dazzle diffuser plate of the prior art; Described anti-dazzle diffuser plate for to add scattering particles in macromolecule translucent cover.
Anti-dazzle diffuser plate described in the utility model is to utilize scattering of light principle, at the inner doping uniformly of macromolecule translucent cover scattering particles, when incident light process scattering particles, by the change direction of propagation of part, in the time that scattering particles diameter is greater than lambda1-wavelength, scattering light wavelength is identical with lambda1-wavelength, thereby, the color of scattered light is identical with incident light, and the colour temperature of explosion-proof lamp does not change.After incident light is scattered, the change direction of propagation of part, at human eye, light not only comes from original light source particle, and some light comes from the region beyond light source particle, thereby, in the time of human eye direct-view explosion-proof lamp light fixture, lamp luminescence point has effectively been pulled open; Realize the brightness that reduces lamp luminescence face, reduced the effect of dazzle value.In addition the light transmittance of anti-dazzle diffuser plate has reached 90%, and light loss reduces greatly.
The utility model also comprises reflector, and described reflector is arranged on aluminium base and is positioned at the dead ahead of LED light source.The utility model arranges reflector, and its Main Function is the rising angle in order to change light source, and light beam is distributed rationally, and reflectivity, utilization ratio are high, thereby can adjust irradiation distance and the scope of light fixture.
In order to reach the object of waterproof, between the utility model light source cover and power supply lid and housing, be provided with sealing gasket.
LED light source described in the utility model is LED light source of the prior art, and its concrete structure the utility model is not described in detail.
Constant-current supply described in the utility model is constant-current supply of the prior art, and its concrete structure the utility model is not described in detail.
The utility model advantage compared with prior art: the anti-dazzle diffuser plate of the utility model, realize the brightness that reduces explosion-proof lamp light-emitting area, reduce the effect of dazzle value, effectively reduce the dizzy sense of human eye.In addition the light transmittance of anti-dazzle diffuser plate of the present utility model has reached 90%, and light loss reduces greatly.
