Description

Metal halogen lamp

[technical field]

The present invention relates to a kind of Metal halogen lamp.

[background technology]

Metal halogen lamp is the third generation green illumination light source that the world today emerges after incandescent lamp, Halogen lamp LED; With advantages such as light efficiency are high, colour rendering is good; Not only become the first-selection of light sources such as high-grade car, back projection TV, also can be widely used in fields such as military affairs, exploration, underwater operation, open-air search and rescue.Compare with ordinary incandescent lamp, the Metal halogen lamp energy-saving effect is remarkable, has wide market application prospect.

But the problem that the ubiquity light-source temperature exceeds standard in the Metal halogen lamp use of traditional development, particularly high-power Metal halogen lamp, the too high meeting of light-source temperature shortens light source life, and use cost increases.

[summary of the invention]

Based on this, be necessary to provide a kind of and can effectively prevent the too high Metal halogen lamp of light-source temperature in the use.

A kind of Metal halogen lamp comprises lamp socket, light source, reflection shield and bright dipping panel; Light source and reflection shield are fixed on the lamp socket; Reflection shield is a parabolic shape; The bright dipping panel is covered in the openend of said reflection shield, and wherein, the luminous point of light source is located on the symmetry axis of reflection shield; And between the focus and bright dipping panel of reflection shield, the luminous point of light source is 5-15mm apart from the distance of focus.

Preferably, luminous point is 10mm apart from the distance of focus.

Preferably, the principal reflection cover of hollow out reached and the adaptive secondary reflector of the middle openwork part of principal reflection cover in the middle of reflector comprised, principal reflection cover and secondary reflector are fixed on the lamp socket, and principal reflection cover and secondary reflector are spliced into parabolic shape.

Preferably, reflection shield is the metal reflector that scribbles reflective membrane.

Preferably, light source is the Metal halogen lamp light source of 1000-2000 watt of power.

Through the light source tuningout is left the reflection shield focus, can reduce reflection and return the light that is gathered in light source luminescent point place, thereby can effectively reduce the temperature of light source in the Metal halogen lamp use, prolong the service life of light source.The Metal halogen lamp of above-mentioned light source focus dislocation design can directly be implemented to improve to conventional lamp, and is simple to operate and effective, but wide popularization and application.

Light source is arranged on 10mm apart from the reflection shield focal length, can reach lamp distribution and reach at the temperature controlled optimum efficiency of voltage fluctuation scope inner light source.

Because the higher three-phase alternating current of Metal halogen lamp working voltage, for realizing that further the open the light protection of process of light fixture is adopted the setting of reflection shield separated into two parts, whole Metal halogen lamp tool safety and reliability in a preferred embodiment.

Reflective membrane plating is put on metal base, and difficult drop-off, rotten further prolongs service life of whole Metal halogen lamp tool.

Metal halogen lamp with said structure can be widely used in the high power illumination occasion, has advantages such as simple in structure, energy-conservation, safe, has huge application market and is worth.

[description of drawings]

Fig. 1 is the structural representation of an embodiment Metal halogen lamp.

[specific embodiment]

Mainly combine accompanying drawing, specific embodiment and testing result that Metal halogen lamp of the present invention is done further detailed explanation below.

As shown in Figure 1, theMetal halogen lamp 100 of an embodiment comprises:lamp socket 110,light source 120,reflection shield 130 and bright dipping panel 140.Light source 120 andreflection shield 130 are fixed on the lamp socket 110.Bright dipping panel 140 is covered in the openend ofreflection shield 130.

Light source 120 is the Metal halogen lamp light source, has higher luminous efficiency and reaches color developing effect preferably.Thelight source 120 of present embodiment has higher power, like Metal halogen lamp light source of 1000-2000 watt of power etc.

Reflection shield 130 is a parabolic shape.Theprincipal reflection cover 132 of hollow out and and the adaptivesecondary reflector 134 ofprincipal reflection cover 132 middle openwork parts in the middle of thereflection shield 130 of present embodiment comprises.The non-reflecting surface ofprincipal reflection cover 132 andsecondary reflector 134 is fixed on the lamp socket 110.Principal reflection cover 132 is spliced into parabolic shape with secondary reflector 134.Because the higher three-phase alternating current ofMetal halogen lamp 100 working voltages,reflection shield 130 separated into two parts settings can realize the open the light protection of process ofMetal halogen lamp 100, wholeMetal halogen lamp 100 safety and reliability.In addition,reflection shield 130 scribbles the metal reflector of reflective membrane for inwall.Reflective membrane plating is put on metal base, and difficult drop-off, rotten further prolongs service life of wholeMetal halogen lamp 100.

Light source 120 to different capacity; For the luminous intensity distribution that reaches wholeMetal halogen lamp 100 reaches the temperature controlled preferable effect at voltage fluctuation scopeinner light source 120; Theluminous point 122 oflight source 120 is located on thesymmetry axis 136 of parabolicshape reflection shield 130, and is located between thefocus 138 andbright dipping panel 140 of reflection shield 130.Theluminous point 122 and the distance between thefocus 138 of present embodiment can be between 5-15mm.Preferably, the distance betweenluminous point 122 and thefocus 138 is 10mm, can reachMetal halogen lamp 100 luminous intensity distributions and reach at voltage fluctuation scopeinner light source 120 temperature controlled optimum efficiencies.

Through withlight source 120 tuningoutfocal point 138 certain distances, can reduce reflection and return the light that is gathered inluminous point 122 places, thereby can effectively reduce the temperature oflight source 120 inMetal halogen lamp 100 uses, prolong the service life oflight source 120.

Have the Metalhalogen lamp 100 of said structure, can be widely used in the high power illumination occasion, the 138 dislocation designs ofluminous point 122, focus, simple in structure, can directly implement to improve to conventional lamp, easy and simple to handle effectively, but wide popularization and application.
