Abstract

The invention relates to a reflector and a tunnel lamp employing the reflector. The reflector approximately has an oblique pysamid shape of which the vertex angle is obliquely cut off, and comprises a bottom surface, and a first reflecting surface, a second reflecting surface, a third reflecting surface and a fourth reflecting surface connected with the bottom surface; the second reflecting surface and the third reflecting surface are in mirror symmetry; and the width of the opening of the reflector along the first direction is greater than that along the second direction, and the first direction is vertical to the second direction. The tunnel lamp comprises a shell and at least two reflectors arranged in the shell, wherein the bottom of each reflector is provided with a light source. After light emitted by the light source is reflected by the reflectors, the light has wide illumination range and can illuminate along the tunnel extending direction, so the tunnel lamp is particularly suitable for lighting long and narrow places such as tunnels or roadways.

The specific embodiment
As shown in Figures 2 and 3, in an embodiment of reflector of the present invention, this reflector 100 roughly is the oblique rectangular pyramid shape of the drift angle of splaying; So-called tiltedly rectangular pyramid is to align rectangular pyramid mutually, is meant that its summit offsets to one side, referring to Fig. 1; Tiltedly the summit 3 of rectangular pyramid 1 offsets to one side, the drift angle 2 of being splayed, and splaying is meant that the cutting face is in a certain angle with the bottom surface of oblique rectangular pyramid 1; Rather than parallel its bottom surface, make peace greatly the prune oblique rectangular pyramid of drift angle 2 of the shape of reflector 100 of the present invention is identical, and the opening edge of reflector 100 is along extending roughly rounded end face 180; It is provided with connecting hole; Be used to be installed in the application scenario, this end face 180 is not necessary, and its shape also can be various.
Reflector 100 comprises bottom surface 110; And first reflective surface 120 that joins with bottom surface 110, second reflective surface 130, the 3rd reflective surface 140 and the 4th reflective surface 150; Wherein, Second reflective surface 130 and the 3rd light-emitting area 140 minute surfaces symmetry, greater than its width along second direction 170, first direction 160 is vertical with second direction 170 along the width of first direction 160 for the opening of reflector 100.This shape of reflector 100 makes the light that is sent by the light source that is arranged on its bottom after its reflection; Bigger range of exposures can be arranged; Can better illumination brightness be provided in a direction (direction that the 4th reflective surface 150 extends); Be fit to the illumination needs of long and narrow occasion such as similar tunnel or tunnel, can good illumination be provided in tunnel and tunnel bearing of trend.
For the vertical direction of the direction that can extend at the 4th reflective surface 150 has suitable illuminating effect; The length at the edge 151 of the 4th reflective surface 150 of reflector is greater than the length at the edge 121 of first reflective surface 120; Because in the present embodiment, four reflective surfaces 120,130,140,150 are slight curving curved surface, and the edge 150 of the 4th reflective surface 150 is by two limits; Its length is breast the tape 153 distance of edge starting point 152; Design makes the reflective surface of reflector be open gradually trend like this, and the vertical direction of the direction that can extend at the 4th reflective surface 150 has suitable illuminating effect.Further, the bottom surface 110 of reflector 100 has and is used for the light source hole 111 that light source passes.
Like Fig. 4, Fig. 5 and shown in Figure 6, in an embodiment of Tunnel Lamp of the present invention, comprise housing 200; And be arranged on four reflector 100 in the housing 200; The bottom of each reflector 100 is provided with light source 300, and reflector 100 is the described reflector of embodiment of reflector of the present invention, and adjacent two reflector 100 minute surfaces are symmetrical set; On the both direction that guarantees like this to extend good illuminating effect can both be provided in the tunnel; In two adjacent reflectors, an illumination of being responsible on the direction, another is responsible for the illumination on the rightabout.The number of reflector is at least two, preferred even number.
In the present embodiment, light source 300 is a led light source, the pasting board 320 that comprises illuminator 310 and be used to place illuminator 310; This pasting board 320 is circuit board or the insulation board that just is used to place LED illuminator 310; In order to prevent heat accumulation, adjacent pasting board 320 is provided with radiator 400 in the bottom of pasting board 320, and this radiator has radiating fin; Can effectively the heat of illuminator and circuit board generation be taken away; Avoid the gathering of heat, making Tunnel Lamp of the present invention go for some needs explosion-proof occasion, like occasions such as mines.
Combine accompanying drawing that embodiments of the invention are described above; But the present invention is not limited to the above-mentioned specific embodiment, and the above-mentioned specific embodiment only is schematically, rather than restrictive; Those of ordinary skill in the art is under enlightenment of the present invention; Not breaking away under the scope situation that aim of the present invention and claim protect, also can make a lot of forms, these all belong within the protection of the present invention.
