Problems solved by technology

Because computer lamps use gas discharge light source, the characteristic of gas discharge light source is that it takes a long time to start up. If you turn off the bulb for standby, you cannot restart it immediately when you need to use up the light. The light effect means that when the light source is on standby for a long time, the light source cannot be turned off, but the outgoing light of the lamp is blocked by a shading plate, which causes the lamp to work at full power when the lamp is not in use or in standby mode, which wastes electric energy

Abstract

The invention relates to technology for dimming and saving energy by inductive ballasts, in particular to a lamp by applying the technology for dimming by inductive ballasts, which belongs to stage illumination technology. The lamp comprises a discharge lamp, an igniter, inductive ballasts and compensating capacitors; and the number of the inductive ballasts is two and the number of the compensating capacitors is two. The lamp also comprises three electronic switches, wherein the first electronic switch is a power switch for a main loop of the lamp and controls the first inductive ballast and the first compensating capacitor; the second electronic switch is a switch for the second inductive ballast; and the third electronic switch is a switch for the second compensating capacitor. When the stage scenery needs spot light, the two inductive ballasts and the two compensating capacitors are all put into operation, and the lamp is in full-power operation; and when the stage scenery does not need the spot light, one of the inductive ballasts and one of the compensating capacitors are withdrawn, and the lamp is in reduced-power operation, so the effect of saving electric energy is achieved. The technology is applicable for lamps which take gas discharge lamps as light sources.

Description

technical field [0001] The invention belongs to the stage lighting technology, in particular to a lamp for dimming by applying the dimming technology of an inductance ballast. Background technique [0002] The computer lights used on the stage are often only used up for a few scene segments, and are basically in a standby state at other times. Because computer lamps use gas discharge light source, the characteristic of gas discharge light source is that it takes a long time to start up. If you turn off the light bulb for standby, you cannot restart it immediately when it needs to be used up. The light effect means that when the lamp is in standby for a long time, the light source cannot be turned off, but the outgoing light of the lamp is blocked by a shade plate, which causes the lamp to work at full power when the lamp is not in use or in standby state, which wastes electric energy. Contents of the invention [0003] In order to solve the above-mentioned problems in the...
