Technical field
The utility model relates to a kind of xenon lamp lamp house structure, particularly relates to a kind of light shading type constant temperature xenon lamp lamp house structure.
Background technology
Lamp house technology is a proprietary technology in special electronic equipment, is mainly to solve electric light source as xenon lamp, and the indirect illumination of mercury lamp and shading heat dissipation problem, be generally applied in Photoelectric Detection, the fields such as microelectronics photolithographic exposure.The light of electric light source is dispersed ejaculation to surrounding, and the object of light source reflecting housing is that luminous energy is converged as wide as possible, along the direction ejaculation of equipment appointment.Because light reflects the temperature rise that causes reflector in reflector, make light source variations in temperature around, and the variation of temperature can cause the variation of light source light spectrum and light intensity, finally causes the unstable of exposure sources and checkout equipment.The method of dealing with problems be generally carry out nature cooling or force cooling, the naturally cooling periphery at reflection shield not specialized designs heat abstractor or at most finned carry out natural heat dissipation, such structure is generally only applicable to the lamp house of small power electric light source.Force cooling lamp house be on naturally cooling basis, add air-cooled fan force blowing, or forced draft is carried out in perforate above reflection shield, or the peripheral coiling cold water pipes at lamp house carries out water-cooled, powerful lighting source lamp chamber during the lamp house of these modes is applicable to.
At present, conventional lamp house structure mainly contains open air discharging and radiating xenon lamp lamp house, closed natural heat dissipation xenon lamp lamp house, closed strong-force exhaust heat radiation xenon lamp lamp house etc.Mainly there is following defect:
Open air discharging and radiating xenon lamp lamp house, its main shortcoming is light leak, causes first light pollution to external world, affects the healthy of workman, and second extraneous veiling glare can be along open optical channel, and directly access arrangement, causes photoelectricity test inaccurate;
Closed natural heat dissipation xenon lamp lamp house, its major defect is that the power of lamp can not be too large, below general 200W, otherwise causes lamp house temperature too high, causes xenon lamp luminescence spectrum to change, effectively the problems such as optical power down of spectral line, are not suitable for high-power applications occasion;
Closed strong-force exhaust heat radiation xenon lamp lamp house, is a kind of comparatively desirable structure, the structures shape in air channel temperature controlled efficiency and the precision of this lamp house, but the structure of straight-line, cannot thoroughly block veiling glare, wind speed is wayward in addition, causes lamp house temperature departure larger.
In view of this, the inventor studies this, develops specially a kind of light shading type constant temperature xenon lamp lamp house structure, and this case produces thus.
Utility model content

Described open light shield is an annulus or Q-RING, is arranged between reflection shield and closed light shield, and its height is lower than the height of closed light shield, and two light shields leave gap in vertical direction, facilitates hot gas to flow.Outside open light shield is mainly used in blocking, the light of horizontal direction approaches lamp house.
Described closed light shield cross section is circular or square.
The inside top of above-mentioned reflection shield is further provided with a temperature sensor, and temperature sensor is connected with controller of fan, by controller of fan and blower fan, realizes closed-loop control.It is consistent that the holding wire of temperature sensor and the wire of xenon lamp are drawn path.
Above-mentioned reflection shield top be further provided with several louvres, for heat radiation.
Described outer cover cross section is square or circular, and for saving space, the area at its top is generally less than bottom.
Above-mentioned light shading type constant temperature xenon lamp lamp house structure, the heat of xenon lamp upwards distributes by the passage of reflector of lamp top, and under the effect of outer cover blower fan, hot-air is made progress by reflection shield, through open light shield top, drop to again closed light shield bottom, pass after wire guide, more upwards flow to the blower fan through hole at outer cover top, be evacuated to the external world, whole air channel presents a sleeping S shape curved structure, on the one hand extraneous veiling glare is repeatedly blocked, and almost cannot enter lamp house; Owing to having blocked hot-air free convection from bottom to top, formed from down to up, then arrived down on the other hand, again to upper, until outside force air wind output channel has been avoided the free convection of air, so outside cold and hot air is little on the impact of lamp house internal temperature, is convenient to mention lamp house accuracy of temperature control.
In addition, described outer cover has sheltered from horizontal veiling glare, the vertical veiling glare entering by outer cover through hole is sealed formula light shield and blocks, the secondary that open light shield carries out again a sub-level veiling glare blocks, the reflection shield of xenon lamp carries out blocking of a sub-level and vertical veiling glare again, so repeatedly complications are blocked, and extraneous veiling glare cannot be entered in the test space of testing equipment.Improved Photoelectric Detection precision, and lamp house constant temperature precision is high, can guarantees that the spectral line of measurement light source is not offset, improve the degree of accuracy of photoelectric measurement.
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
