The specific embodiment
In order to make the object of the invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
The embodiment of the invention provides a kind of lamp reflector, and its bottom is provided with through hole, and inner surface is provided with reflecting surface, the rectangular pyramid structure that this reflecting surface is made up of four inclined-planes;
Wherein, relative inclined-plane is a mirror image;
Angle between the central shaft of each inclined-plane and reflecting surface is 23 °～25 °;
The surface of reflecting surface is provided with diffuse reflector.
The embodiment of the invention also provides a kind of portable lamp, comprises lamp holder, lamp body and tail-hood, is provided with light source and reflector in the lamp holder, and the openend of reflector is provided with transparent member, and this reflector is above-mentioned reflector; Light source passes the through hole of reflector, and its luminous point is positioned on the central shaft of reflecting surface of reflector.
The reflecting surface of the present invention's lamp reflector is set to the rectangular pyramid type structure of relative flat inclined mirror picture symmetry; Can form rectangular light spot, the angle of each inclined-plane and reflecting surface central shaft is set to 23 °～25 °, and diffuse reflector is set on reflecting surface; Can obtain than high evenness; And the suitable rectangular light spot of size, the demand of special occasions such as criminal investigation prospecting has been satisfied in and the brightness that helps improving hot spot.
Below in conjunction with specific embodiment concrete realization of the present invention is described in detail:
Embodiment one:
The master that Fig. 1,2,3 shows the reflector that first embodiment of the invention provides respectively looks, section and plan structure sketch map, for the ease of explanation, only shows the part relevant with present embodiment.
This reflector is used for portable lamp more, is used to form the rectangular illumination hot spot.The bottom of this reflector is provided with the through hole 1 that a confession light source passes, and the inner surface of reflector is provided with reflecting surface 2, and this reflecting surface comprises four inclined-planes 21, and these four inclined-planes have formed rectangular pyramid type structure, and two relative inclined-planes are mirror image.The light that light source sends is invested a distant place through reflecting surface reflection back; On shadow surface, form rectangular light spot; The needs that satisfy special occasions such as criminal investigation for the size that makes rectangular light spot and the uniformity; Each inclined-plane 21 is set to 23 °～25 ° with the angle of reflecting surface central shaft, and on the surface of reflecting surface 2 the diffuse reflector (not shown) is set.When the angle of each inclined-plane and reflecting surface central shaft during greater than 25 °, though the size of hot spot is big, but illumination does not reach requirement, and during less than 23 °, the diameter of hot spot is less than normal, is unfavorable for the requirement of on-the-spot illumination.
The reflector of this structure can form large scale (the criminal investigation system reconnoitres the spot vestige and the required spot size of special occasions such as the evidence obtaining of taking pictures); And uniformity is rectangular light spot preferably; And, can also guarantee further that hot spot has higher brightness.
