Lamp cup type cold light lamp control system capable of adjusting light one by one

Abstract

The invention discloses a lamp cup type cold light lamp control system capable of adjusting light one by one, which comprises a singlechip, a filter, a reducing transformer, a full-wave rectification circuit, a zero detection circuit, a three terminal regulator and a plurality of lamp cup control circuits. Each lamp cup control circuit comprises an optoelectronic isolation drive controller, a silicon controlled power controller, a halogen lamp transformer and the like, and the singlechip is respectively connected with all the lamp cup control circuits. The control system adopts an independentcontrol method and uses the singlechip and power electronic devices to conduct light adjustment control on each lamp cup in the lamp cup type clod light lamp so as to adjust light of each lamp cup one by one. In light adjustment, one lamp cup can be in light adjustment state, while others are in work or switched off, therefore, color temperature can keep unchanged basically and the different requirements of all stage performances on stage light can be met.

Description

technical field [0001] The invention relates to a stage lamp control system, in particular to a stage lamp control system which uses a single-chip microcomputer to control a lamp cup-type cold light lamp so as to realize dimming one by one, and belongs to the field of lighting technology. Background technique [0002] In stage performances and film and television shooting, stage film and television lamps play a very important role. It helps to express the content of the program, reflects the author's creative intention, highlights the artistic atmosphere, and enables the audience and the camera (image) machine to get the correct color perception and exposure. At present, there are many kinds of lights used for stage film and television lighting, such as spotlights, floodlights, soft lights, zoom imaging lights, etc. These lamps have a common feature, that is, there is only one light source, and operations such as spotlight adjustment, astigmatism control, and zooming need t...

AI Technical Summary

Problems solved by technology

Since the lamp cups are connected in series in the circuit, as long as one fails, it cannot be used normally under 220V voltage, thus affecting the brightness of the entire stage lamp

In addition, the stage film and television lamps using this kind of lamp cup type cold light lamp cannot adjust the brightness of each lamp cup one by one, and cannot fully meet the different needs of various stage performances for lighting.
