Light path structure of laser movie and television photography lighting lamp

Abstract

The invention discloses a light path structure of a laser movie and television photography lighting lamp. The structure comprises a blue semiconductor laser (1), a red semiconductor laser (2), a greensemiconductor laser (3), an LED lamp bead (4), a lens I (5a), a reflector I (6a), a lens i (5b), a reflector i (6b), a yellow-reflection red-green-blue beam combiner (7), a lens II (8a), a lens III (9a), a lens ii (9b), a reflector II (10), an optical filter (11), a large light transmission pipe (12), a reflector III (13), a lens (14),a blue semiconductor laser I (15), a dispersion sheet (16), asmall light transmission pipe (17), a reflector IV (18), a lens IV (19), a lens V (20) and a fluorescent wheel (21). The light path structure with small divergence angle, high power and uniform illumination developed by the invention has the advantages of high brightness, long service life, no pollution, no speckle and the like of a laser fluorescent light source.

Description

technical field [0001] The invention belongs to the technical field of laser lighting, and specifically relates to a light path structure of a laser lighting fixture for film and television photography, which can be used as lighting or supplementary light for studios, news halls, studios and stages. Background technique [0002] In low light, backlight or indoor working environment, if you want to shoot clear and high-quality pictures, sufficient light is very necessary. Photographic light is a kind of auxiliary light source commonly used in news studios or studios and studios. [0003] At present, the types of photography lights on the market include LED lights, spotlights, flash lights, back lights, news lights, etc. LED lights have the advantages of energy saving and long life, but their power is small and their luminous flux is low; spotlights use point light sources, and the irradiation range is adjustable. The supporting accessories of this kind of lamps are not comp...

AI Technical Summary

Problems solved by technology

[0005] At present, the film and television lighting fixtures on the market have poor adaptability to sudden changes in cold and heat, and there are problems such as black centers in the light area and uneven illumination, resulting in a relatively low overall luminous flux rate. Aiming at the shortage of photographic lamps on the market and the development prospects of photographic lamps, the present invention mainly focuses on The purpose is to propose a light path structure of laser film and television photography lighting lamps to achieve uniform light output, small divergence angle, and high brightness.
