Reflection type light-emitting diode (LED) cyclorama light

Abstract

The invention discloses a reflection type light-emitting diode (LED) cyclorama light. The reflection type LED cyclorama light comprises an LED light source (1), a base board (2) provided with a control circuit, and a light-reflecting board (5), wherein the LED light source (1) is arranged on the base board (2); the base board (2) is fixed on the light-reflecting board (5); and the light-emitting direction of the LED light source (1) faces the light-reflecting board (5) and the arrangement position of the LED light source (1) leans to one side of the light-reflecting board (5), so that the light emitted to a light high-density range of the light-reflecting board is reflected to one side, which is close to the LED light source (1), of a lighted object, and the light emitted to a light low-density range of the light-reflecting board is reflected to one side, which is far away from the LED light source (1), of the lighted object. The reflection type LED cyclorama light can generate an asymmetric light field with uniform illumination in each distance.

Description

technical field [0001] The invention relates to a reflective LED sky curtain light for film and television stage lighting, and belongs to the technical field of film and television stage lighting. Background technique [0002] Sky curtain lights are essential lighting fixtures for stage lighting in theaters and studios. It can illuminate the stage sky in a large area to make the sky bright and the background bright to increase the performance effect and make the performance more dynamic. At present, there are many kinds of skylights used on the stage, most of which use halogen tungsten light source. Tungsten-halogen lamps are thermal light sources, about 90% of the consumed electric energy is converted into heat energy, and about 10% is converted into visible light. In order to get enough brightness and meet the needs of stage lighting, it is necessary to increase the number of lamps and increase the power of the bulb. This will cause the indoor ambient temperature to be ...

AI Technical Summary

Problems solved by technology

[0005] However, the above-mentioned high-power LED skylights use LED light source modules with different beam angles to be installed on different installation surfaces to generate asymmetric light fields to meet the needs of stage illumination. The disadvantage is that LED light sources with various beam angles must be selected when making lamps. , installed on the installation surface with different angles, which brings some troubles to the production

Moreover, the light sources of the light outlets of all skylights are direct light, which is dazzling to actors who are in close contact

In addition, although the power of the LED is small, the point light source formed by the LED is very dazzling, and it is easy to produce dazzling glare.

The light-emitting device made of LED is used for indoor lighting and is close to the human body, which is very irritating to the eyes and easily causes eye damage
