Problems solved by technology
However, in the ports and freight yards of ships and civil aviation, high-pole floodlights are mainly used for lighting. When the above-mentioned light distribution lens is applied to lamps installed on 18-20-meter-high poles, due to its low light distribution, it is difficult to Unable to meet the lighting requirements of ports and freight yards

The invention discloses a lens. The lens is a rotator taking an optical axis as a rotary axis. The lens comprises a reflecting surface, and a light incidence surface and a light outgoing surface, arranged at the two ends of the reflecting surface, wherein a light source accommodating cavity is formed in the light incidence surface and comprises a bottom and a side wall; the bottom is a convex curved surface and is used for refracting light emitted by a light source in a range of plus or minus 35 degrees to the light outgoing surface and refracting light of an included angle of of 0 to minus / plus 19 degrees with the optical axis of the lens through the light outgoing surface; the side wall is a conical concave surface taking an optical axis as a central axis and is used for refracting light emitted by the light source in a range of minus 90 degrees to minus 35 degrees and plus 35 degrees to plus 90 degrees to the reflecting surface, reflecting the light from the reflecting surface to the light outgoing surface and refracting light forming of an included angle of 0 to minus / plus 15 degrees with the optical axis of the lens through the light outgoing surface; and after the light is overlapped with the light refracted by the bottom, light beams with half light intensity angles of in a range of 20 + / - 5 degrees are formed. The lens provided by the invention has the advantages of being simple in structure and easy to massively produce. Besides, the invention further provides a lens module having the lens and a lamp having the lens module.
Description
technical field [0001] The invention relates to the field of light distribution of LED lamps, in particular to a lens, a lens module and a lamp. Background technique [0002] As traditional incandescent light bulbs gradually fade out of the historical stage, the fourth-generation solid-state light source represented by LED has gradually established its core leadership in the lighting field. LED (Light Emitting Diode) has become a competitive new light source in the 21st century due to its high efficiency, pure light color, low energy consumption, long life, and no pollution. With the continuous improvement of LED luminous flux and luminous efficiency, the application of LED in the field of lighting is becoming more and more extensive. However, the light emitted from the surface of LED chips has a Lambertian distribution, which cannot be directly applied to lighting systems. Therefore, the secondary light distribution design using LED as the light source is particularly imp...
