Multifunctional support in gas discharge lamp

Abstract

The invention relates to a multifunctional support in a gas discharge lamp. The multifunctional support comprises bearing pieces which are provided with support holes and are matched with the section shape of a glass envelope, wherein the outer edge of each bearing piece is provided with a flanging, the surface of each bearing piece is provided with a stretching hole, the bearing pieces are arranged in the glass envelope, and the flanging at the outer edge of each bearing piece is in clearance and sliding fit with the inner wall of the glass envelope; each bearing piece is a whole wafer, the structure is simple and easy to manufacture, the heat insulation and light reflection effects are better, the bearing pieces and a support hole edge flanging can be used for enhancing the mechanical strength of the bearing pieces, and the stretching hole can be used for facilitating the expansion and contraction of materials; the two ends of an electric arc pipe are respectively fixedly provided with one bearing piece, bilateral rays are centrally reflected on a reflector, and the lighting efficiency of the lamp is improved; the safeguard of the bearing pieces at two ends can reduce heat generated by ray radiation, the temperature of a lamp holder and other connecting devices is controlled at about 50 DEG C, and the lamp holder and the other connecting devices can not loosen due to super hot condition and deformation; and the multifunctional support integrates multiple functions such as support, fixation, heat insulation, light reflection and the like into a whole, the defect of single function of the existing support is improved and perfected, and the use is more safe and reliable.

Description

technical field [0001] The invention relates to an important part in a gas discharge lamp, in particular to a multifunctional support in a gas discharge lamp for fixing an arc tube. Background technique [0002] Due to the high luminous efficiency, low power consumption and long service life of gas discharge lamps, they have been widely used in roads, airports, docks and plant cultivation lighting and other places. The arc tubes of gas discharge lamps are generally used in closed glass bulb lamps , the temperature is very high during normal operation, and the support and fixing frame of the arc tube in the existing gas discharge lamp only have the function of supporting and fixing, and there is no heat insulation and reflection effect, so after a long working time, the discharge lamp The high temperature makes the lamp caps at both ends of the lamp tube burnt black and the glass bulb cracks occur from time to time, which directly affects the service life of the lamp.

Problems solved by technology

[0002] Due to the high luminous efficiency, low power consumption and long service life of gas discharge lamps, they have been widely used in places such as roads, airports, docks and plant cultivation lighting. The arc tubes of gas discharge lamps are generally used in closed glass bulb lamps , the temperature is very high during normal operation, and the support and fixing frame of the arc tube in the existing gas discharge lamp only have the function of supporting and fixing, and there is no function of heat insulation and reflection. Therefore, after a long working time, the discharge lamp The temperature is very high, so that the lamp caps at both ends of the lamp tube burn black and the glass bulb cracks occur from time to time, which directly affects the service life of the lamp

[0003] Patent No. CN200820159867.1 "Fixer for Explosion-proof Metal Halide Lamp Explosion-proof Tube" and 200820159869.0 "Support for High Luminous Efficiency Sodium Lamp" disclose that the fixed frame and support frame are only for supporting and fixing, and their functions are relatively single
