Abstract
The utility model relates to an electric arc tube for a pulse start mental halide lamp, which comprises a quartz glass bulb shell and an electrode component sealed in the two ends of the electric arc tube. The bulb comprises an olive-shaped discharging part and an electrode encapsulation part connected with the two ends of the discharging part, a zirconia coating layer is arranged at the connection point of the two ends of the discharging part and the electrode encapsulation part. Compared with the electric arc tube of the traditional mental halide lamp which is directly sealed by the quartz tubing of straight tube, the electric arc tube for a pulse start mental halide lamp provided by the utility model has the advantages that the pinch sealing area of the electric arc tube is reduced, the thermal conductivity loss of the pinch sealing part and the radiation heat loss of the bulb shell are reduced, the operating temperature of the bulb shell is improved, the metal halide participating in discharging is more and light efficiency of the lamp is increased remarkably. As the shape of the cavity of the electric arc tube is matched with that of the electric arc, the temperature distribution of the electric arc tube is more uniform, the temperature difference between all parts of the electric arc tube is reduced, the color temperature drift of the lamp is reduced and the consistency of light and color is better. Furthermore, the design is in favor of the operation of the electric arc tube under high pressure and at high temperature, and the service life is longer.
Description
Technical field
The utility model relates to the electric light source technology field, particularly a kind of pulse enable Metal halogen lamp electric arc tube.
Background technology
The lumen that improves Metal halogen lamp is important problem in the present electric light source technology field, and the set shape of change electric arc tube is the most direct approach.Traditional halogen electric arc tube is directly by the quartz ampoule compression moulding of straight tube shape, power and photoelectric parameter for guarantee fund's halogen lamp, the press seal position area of common this electric arc tube is very big, whole electric arc tube is also heavier, thermal conductance loss and the thermal radiation loss of cell-shell of the electric arc tube of this press seal by the press seal position is more serious, the temperature difference at each position of electric arc tube is bigger, bulb temperature is lower simultaneously, there is more metal halide can not enter discharge space, like this, the photochromic consistency of Metal halogen lamp is just good inadequately naturally, and light efficiency can not effectively be brought into play and improve.
The utility model content
The purpose of this utility model is to provide the pulse enable Metal halogen lamp electric arc tube that a kind of photoelectric parameter consistency is better, light efficiency is higher.
The technical scheme that realizes the utility model purpose is: a kind of pulse enable Metal halogen lamp electric arc tube has quartz glass cell-shell and the electrode assemblie of enclosing its two ends; Described cell-shell is made up of with the electrode package portion that is connected the discharge part two ends olivary discharge part, and discharge part two ends and electrode package portion junction are provided with the zirconia coat.
Above-mentioned pulse enable Metal halogen lamp is the quartz glass integral piece with the cell-shell discharge part and the electrode package portion of electric arc tube.
Above-mentioned pulse enable Metal halogen lamp is provided with blast pipe with the olive shape discharge part housing of the cell-shell of electric arc tube.
The utlity model has following characteristics: the arc shape when pulse enable Metal halogen lamp of the present utility model is worked with electric arc tube and Metal halogen lamp coincide, with traditional directly comparing by the halogen electric arc tube of straight tube shape quartz ampoule sealing-in, following advantage is arranged: 1, the press seal area of electric arc tube reduces, thermal conductance loss and cell-shell thermal radiation loss by the press seal position reduce, the cell-shell working temperature improves, the metal halide that participates in discharge is more, and the light transmittance efficiency of lamp significantly improves more than 20%; 2, because arc tube chamber body profile and electric arc self shape are identical, thereby the Temperature Distribution of electric arc tube is more even, and the temperature difference at each position of electric arc tube reduces, and the colour temperature drift of lamp reduces, photochromic consistency is better, and this design more helps electric arc tube and works under hyperbar and high temperature; 3, because this metal halide lamp adopts pulse enable, lamp can more worked under the hyperbar again, so the startup of lamp and the time of restarting can shorten more than 50%, has also reduced the blackout of lamp simultaneously, can be than conventional lights life-saving more than 30%.
Description of drawings
For the easier quilt of content of the present utility model is clearly understood, below the specific embodiment and in conjunction with the accompanying drawings of basis, the utility model is described in further detail, wherein
Fig. 1 is a structural representation of the present utility model.
Embodiment
(embodiment 1)
