Beam angle, and the emergent ray of its LED light source can be decomposed, to ensure that the emergent ray of bulkhead lamp is evenly distributed, carried
The high light utilization to LED light source, and avoid glare effects.When the optical lens is used for model Philips LUXEON M
Packaged high-power LED is lighting source (i.e. light source is Lambertian light source) when matching somebody with somebody light, first passes through the installation portion of lens body 10
101 so that whole light source part is fixedly arranged in the mounting seat of bulkhead lamp, and the LED light source coaxial line then is arranged at into lens master
In the light-source chamber 103 of body 10, then the lighting angle that now bulkhead lamp can be achieved is 60 °, and its emergent ray is evenly distributed, so as to
Avoid light loss, light wasting phenomenon so that beam angle diminishes, effective light increase, to lift the lighting condition of factory building working face.
Specifically, the optical lens is that the light sent by LED light source passes through light with photoreduction process to above-mentioned LED light source
The side wall and roof plane of refraction 1031 of source chamber 103 enter lens section 102, into light again in the reflecting surface 1021 of lens section 102
Total reflection prism and the internal face convex lens of transmission plane 1022 collective effect under so that point of the light of LED light source in space
Cloth situation is that the angle between 0 ° of its normal direction and its half maximum emission intensity value is 60 °, so as to realize to LED light source light
The convergence of line, its lighting angle is diminished, and avoid glare effects, the light being then emitted by transmission plane 102 is again in light master
Under the auxiliary of the fly's-eye lens of body 20, the circular light spot being emitted through lens body 10 is decomposed, to obtain high luminous energy profit
With rate so that the light that factory building working face receives is more uniform.
Embodiment of the present utility model is described in detail above, but the content is only of the present utility model preferable
Embodiment, it is impossible to be considered as being used to limit practical range of the present utility model.All impartial changes made according to the scope of the utility model
Change and improvement etc., all should still be belonged within this patent covering scope.
