Abstract
The utility model discloses a 175W metal halide lamp. The 175W metal halide lamp comprises a lamp cap and a glass bulb, a quartz electric arc tube is packaged inside the glass bulb, the quartz electric arc tube is one with an olive-shaped light emitting bulb shell, tungsten electrodes are packaged at both ends of the light emitting bulb shell, the maximum diameter of the center of a cavity of the light emitting bulb shell is 14 mm, the arc radius inside the light emitting bulb shell cavity is 22.26 mm, the axial length of the light emitting bulb shell cavity is 29 mm, distance of two electrode discharge ends is 19 mm, and the bulb shell is internally provided with metal halide pills, and is filled with mercury and mixed gas of argon and krypton. The 175W metal halide lamp has high initial luminous flux, relatively high luminous flux can still be maintained after 2000 hours, the luminous efficiency is high, and the service life is long.
Description
Technical field
The utility model relates to a kind of lighting, especially a kind of metal halide high-voltage gas discharging light.
Background technology
Metal halide high-voltage gas discharging light has that light efficiency is high, long service life, color rendering are good, compact conformation, steady performance, is widely used in the illumination in the places such as stadiums, conference and exhibition center, megastore, industrial premises, square, street, station, harbour.The initial luminous flux of 175W Metal halogen lamp of the prior art is many below 15000lm, 2000 hours luminous flux 10500lm left and right, because real beginning light flux values is lower, this Metal halogen lamp is after work a period of time, even if reach the lux maintenance of GB regulation, its light flux values is lower, and light efficiency also decreases.
Utility model content
The technical problem that utility model will solve is: a kind of 175W metal halide lamp is provided, and this 175W metal halide lamp initial luminous flux is high, after 2000 hours, can also keep higher luminous flux, and light efficiency is high, long service life.
The technical scheme that technical solution problem adopts: a kind of 175W metal halide lamp, comprise lamp holder, glass bulb, in glass bulb, be packaged with quartz arc tube, described quartz arc tube is the luminous cell-shell quartz arc tube of olive shape, be packaged with tungsten electrode at luminous cell-shell two ends, 14 millimeters of the maximum gauges at luminous cell-shell cavity center, 22.26 millimeters of luminous cell-shell chamber arc radiuses, 29 millimeters of luminous cell-shell cavity axial lengths, two electrode discharge ends are apart from 19 millimeters, metal halide pill is housed in cell-shell, is filled with mercury and argon krypton gaseous mixture.
0.8-1.2 millimeters of luminous cell-shell wall thickness.
On the outer wall at olive shape cell-shell two ends, scribble heat insulation coating, heat insulation coating is 6-7 millimeters along the axial projection width of cell-shell.
Beneficial effect: a kind of 175W metal halide lamp of the present utility model, owing to having adopted described 175W metal halide lamp to comprise lamp holder, glass bulb, in glass bulb, be packaged with quartz arc tube, described quartz arc tube is the luminous cell-shell quartz arc tube of olive shape, be packaged with tungsten electrode at luminous cell-shell two ends, 14 millimeters of the maximum gauges at luminous cell-shell cavity center, 22.26 millimeters of luminous cell-shell chamber arc radiuses, 29 millimeters of luminous cell-shell cavity axial lengths, two electrode discharge ends are apart from 19 millimeters, metal halide pill is housed in cell-shell, mercury and argon krypton gaseous mixture technical scheme, by limiting the shape and size of quartz arc tube cell-shell, the bulb of electric arc tube volume of 175W metal halide lamp of the present utility model is further dwindled, radian in cell-shell cavity more approaches electric arc radian, each space and pill that arc energy is fully arrived in cell-shell cavity react, more than the initial luminous flux of 175W metal halide lamp of the present utility model can be stablized and reaches 15400lm, the lux maintenance of 2000 hours can be stablized and remains on more than 75%, therefore, it is high that 175W metal halide lamp of the present utility model has light efficiency, the advantages such as long service life, scribble heat insulation coating owing to having adopted on the outer wall at olive shape cell-shell two ends, and reasonably define the width of heat insulation coating, in improving the temperature of electric arc tube cold junction, the output that can not shut out the light, has improved light efficiency and the startability of the utility model 175W metal halide lamp.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the structural representation of the electric arc tube of the utility model 175W metal halide lamp.
Embodiment
