Novel movie and stage lighting lamp

Abstract

The invention relates to a novel movie and stage lighting lamp, belonging to the technical field of movie and stage lighting devices. The light path of the lighting lamp is composed of a light source, a reflective bowl, an intermediate convergence lens, a folding line-shaped light-collecting device and a light emergent lens; a high lighting effect and high-quality light spots are obtained by adopting the parabolic reflective bowl with a light receiving margin, an aspherical surface intermittent converging lens with a vacuum heat isolating layer, the folding line-shaped light-collecting device and the light emergent lens to control pitching angles by virtue of a focus control device and a light emergent lens tilting adjusting device; and in a lamp body, through the air natural convection from a ventilation air inlet at the front end of the lamp to a light source base heat dissipation channel and the heat insulation and heat dissipation design of optical components and by adopting a light source base with heat dissipation seams and a tilting low-wind resistance heat dissipation structure of ring type heat dissipation wing, the low noise requirement of the lamp is realized by virtue of the natural ventilation and heat dissipation. The novel movie and stage lighting lamp provided by the invention has the characteristics of high light efficacy, low energy consumption, low noise, high-quality light spots and suitability for movie shooting and theater stage lighting.

Description

technical field [0001] The invention belongs to the technical field of film and television and stage lighting equipment, and in particular relates to a novel film and stage lighting fixture. Background technique [0002] The extremely inconvenient adjustment method of conventional lamps currently used for film and television and stage lighting has become an obstacle to the professional development and innovation of film and television and stage lighting. A consensus has been formed in the industry to replace conventional lamps with intelligent lamps. Manufacturers of smart lamps (computer lamps) have introduced intelligent substitutes for conventional lamps, and tried to replace some of the functions of conventional lamps with dyed computer lamps, and achieved good results, promoting the elimination of conventional lamps in the industry, and then eliminating the use of conventional lamps Advanced dimming cabinets, color changers, and conventional lamp consoles make the light...

AI Technical Summary

Problems solved by technology

If a spherical reflective bowl is used, the light effect will be worse

[0006] (2) Although the luminous efficiency of some simple structure lamps is high (it will not exceed 50%), the quality of the light spot is poor

[0007] (3) Due to the heating of the light source and the heat dissipation of the lamp body, the increase in the inclusion angle of the reflective bowl is affected, and the light effect is limited. The life of the light source, the life of the reflective bowl, optical lenses, color chips, stepping motors, control circuit boards, and wires The life of other internal components of the lamp is affected, especially the cooling fan has become an indispensable part, which makes the noise of the lamp remain high

[0008] (4) There are few light source specifications, and the zoom range of lamps is small, which makes it difficult to meet the requirements of long-distance surface light, ear light, and side light lighting.

[0009] (5) Due to the limitation of heat dissipation, light source, light effect of lamps and other reasons, the light output of tungsten-halogen light source computer lights is generally low, which seems powerless in performances, and it is difficult to achieve the artistic effect of conventional lights.

[0010] (6) The light spot is single, usually a circular spot, without spot shape correction, and when it is irradiated obliquely, an elliptical spot is formed on the ground, with uneven brightness, dark in the distance and bright in the near, and it is difficult to superimpose the spot

[0011] In short, conventional lamps and existing computer lamps have four problems of heat dissipation, noise, light effect and spot quality. Among them, heat dissipation and spot quality are the core. The noise cannot be reduced, and the light effect cannot be improved. Most of them are related to heat dissipation.

Poor spot quality, not suitable for stage, film and television and other art lighting places
