Abstract
The invention relates to a high-efficient reflector used for an electrodeless lamp, which comprises a bowl-shaped reflecting shade, wherein the reflecting surface of the reflecting shade is a curved surface formed by one section of involute which is in a same plane with a central axis of the reflecting shade and revolves around the central axis once, namely an integral curved surface. In order to ensure that the reflecting efficiency is above 95%, the light-emitting surface of the electrodeless lamp in the reflecting shade is arranged in a base circle of the involute. According to the reflection theorem, an incidence angle is equal to a reflection angle, as the curved surface radiuses of the involute are the tangent lines of the base circle, namely, a normal line of the light reflection, the structure of an illuminator disclosed by the invention solves the problem that the light emitted by the most of light emitting surface of the light source cannot be reflected to the light emitting surface of the light source, and therefore, the illuminator disclosed by the invention has the characteristics of simple structure and high reflecting efficiency. The reflector adopts an integral curved surface or a split-jointing scheme of splice plates, the split jointing scheme of the splice plates is adopted to replace the integral curved surface, and thus, the processing is convenient and the production cost can be reduced.
Description
Technical field
The present invention relates to the light reflector device, be specifically related to a kind of electrodeless lamp efficient reflector.
Background technology
The conventional lighting sources reflex reflector, in use some light reflected back light sources all causes the reflector efficiency of reflector lower, causes accelerated ageings such as light source hot-spot or fluorescent material simultaneously, influences the service life of light source.
Summary of the invention
Technical problem to be solved by this invention provides a kind of simple in structure, reflector efficiency up to the electrodeless lamp efficient reflector more than 95%.
For solving the problems of the technologies described above, electrodeless lamp efficient reflector of the present invention, comprise the reflection shield that is bowl-shape, the reflective surface of this reflection shield is to be rotated a circle and the curved surface that constitutes around this central axis by one section isoplanar involute of the central axis with this reflection shield, i.e. the monoblock type curved surface.
Further, for guaranteeing reflector efficiency more than 95%, the light-emitting area of the electrodeless lamp in the described reflection shield is located in the basic circle of described involute.
As the electrodeless lamp efficient reflector of another kind, it is characterized in that comprising: be bowl-shape reflection shield, the reflective surface of this reflection shield is the curved surface that the jigsaw by a plurality of petal types is spliced; The axial section of described jigsaw is one section isoplanar involute of the central axis with this reflection shield, and the horizontal section of this jigsaw is a straightway.For guaranteeing reflector efficiency more than 95%, the light-emitting area of the electrodeless lamp in the described reflection shield is located in the basic circle of described involute.
The present invention has positive effect: (1) is according to the reflection of light theorem: incidence angle equals angle of reflection, because the subsequent corrosion of involute all is tangent lines of basic circle, i.e. and the normal of light reflection.Therefore, the structure of photophore of the present invention has solved light source and has sent out the light that the light-emitting area of the overwhelming majority is sent, light-emitting areas that can the reflected back light source, and therefore photophore of the present invention has characteristics simple in structure, that reflector efficiency is high.(2) this reflector adopts the scheme of monoblock type curved surface or the splicing of employing jigsaw, because the difficulty of processing of monoblock type curved surface is bigger, cost is higher; The scheme that adopts the jigsaw splicing can conveniently be processed, and reduce production costs to substitute above-mentioned monoblock type curved surface.
