Problems solved by technology
The gas discharge bulbs used in stage lights usually have strict temperature control and protection, such as the temperature of the center of the luminous body, the temperature of the bulb molybdenum sheet and the front lead wire of the bulb, etc., and the molybdenum sheet and front lead wire are often caused by excessive temperature. Oxidation or even fusing will affect the normal use of the light source and shorten the life of the lamp

Embodiment Construction
[0024] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0025] Such as Figure 1 to Figure 6 As shown, a light bulb overheating protection structure includes a light bulb 100, a heat insulation layer (200a, 200b, 200c) and a color filter 300 arranged in sequence. The light bulb 100 includes a bulb holder 110 , a reflective bowl 120 arranged on the bulb holder 110 , a luminous body 130 connected to the bulb holder 110 and located at the center of the reflective bowl 120 , and a front lead 140 connected between the luminous body 130 and the bulb holder 110 . Frosted parts (210a, 210b, 210c) are arranged on the heat insulation layer (200a, 200b, 200c), and the frosted parts (210a, 210b, 210c) are located on the axis of the luminous body 130 and correspond to the spherical center of the luminous body 130 and the front end lead 140 .
[0026] By providing a heat insulating layer (200a, 200b, 200c) between the ...

The invention discloses a bulb overheating protection structure and a stage lamp. The bulb overheating protection structure comprises a bulb, a thermal insulation layer and a color filter which are sequentially arranged. The bulb comprises a bulb socket, a reflector arranged above the bulb socket, and an illuminant connected to the bulb socket and located at the center of the reflector. A front-end lead wire is arranged between the illuminant and the bulb socket. The thermal insulation layer is provided with a frosted portion located on the axis of the illuminant, and the frosted portion corresponds to the sphere center of the illuminant and the front-end lead wire. According to the invention, the temperature of the bulb and the lamp can be reduced, so that the lamp can be protected.
Description
technical field [0001] The invention relates to the field of lighting technology, in particular to a light bulb overheat protection structure and a stage lamp. Background technique [0002] With the improvement of people's living standards, the development of cultural and entertainment industries has higher and higher requirements for the construction of lighting large-scale opera houses and stages. Superb lighting interpretation technology can bring more shocking visual impact to people, and stage lighting design can better integrate with art while absorbing new technologies. Therefore, the demand for high-power stage lights has increased dramatically. The gas discharge bulbs used in stage lights usually have strict temperature control and protection, such as the temperature of the center of the luminous body, the temperature of the bulb molybdenum sheet and the front lead wire of the bulb, etc., and the molybdenum sheet and front lead wire are often caused by excessive te...
