Description

Stage lighting structure with multiple high-intensity discharge lamps

technical field

The utility model relates to a lamp structure, in particular to a stage lamp structure with a plurality of high-intensity gas discharge lamps for the stage.

Background technique

High-intensity discharge lamps (High Intensity Discharge, HID) use high-voltage discharges to generate arcs to emit light. Compared with traditional metal halide bulbs, high-intensity discharge lamps have the advantages of high illuminance, low power consumption and high durability, so they are gradually used in various lighting equipment, such as stadium lighting, automobile headlights, Projector lights and stage lights, etc.

Taking the stage application as an example, when arranging stage lighting, in order to achieve the stage lighting effect, stage lights of various light intensities are usually mixed and matched to achieve the required stage lighting effect. Among them, stage lights with high light intensity usually need to be matched with high-wattage high-intensity discharge lamps (HID). However, although high-wattage stage lights can produce brighter lighting effects, they also generate more heat per unit time, making the operating temperature of high-wattage stage lights much higher than that of low-wattage stage lights. Affected by high temperature, stage lights with high light intensity will be easily damaged by stage lights with low light intensity, which increases the maintenance cost or purchase cost of the stage lighting layout industry. Therefore, how to increase the service life of stage lights with high light intensity will be one of the focuses of research and development personnel.
