Stage Lighting Technician School: Stage Lighting Control Skills

After using the light, the bulb will absorb water molecules in the air during the process of changing from heat to cold, and these water molecules will stay on the glass shell of the bulb and gather. When you suddenly push the light bulb, the water molecules on the glass shell have the same effect as filling water in a hot oil pan, and it is only natural for the light bulb to burst. The success of theater lighting design is marked by the proper handling of stage lighting. Stage lighting should not only illuminate the actors, let the audience see the facial expressions, expressions and movements, but more importantly, make full use of lighting technology, mobilize lighting operations and other means to strengthen the artistic effect, so that the audience has a sense of being on the scene.

Computer shaking head lamp electrical and program control part

1. Before the electrical characteristics and circuit design of computer shaking head lamps, the vast majority of professional 1200W shaking head computer lamps worldwide used rare gas discharge bulb light sources. The starting and stable operation of the gas discharge bubble depends on the design of the circuit type, the choice of electrical components such as power supply and ballast. After the rare gas discharge bulb is started, generally no stabilization time is required. In order to ensure stabilization, the difference between the maintaining voltage of the circuit and the instantaneous voltage of the bulb should be sufficiently large during the entire AC cycle. The starting, stability, extinguishing and restarting of the light source should be designed according to the characteristics of the light source. rare gas discharge bubble
