Problems solved by technology

[0003] Due to the small size of the LED lamp, the light irradiation range after it emits light is relatively small. Using a single LED lamp as a lamp lighting is not suitable for some occasions with relatively high lighting requirements, such as dark and narrow tunnel environments; in addition, currently Generally, a conical reflector is used to reflect the light emitted by the LED lamp. After the light is reflected by the conical reflector, the radiation angle or range of the light formed is a conical shape. The extension direction provides good light brightness; if you want to increase the light brightness in the extension direction of a narrow tunnel, you need to add LED lamps at different positions to achieve it, which increases the operating cost

Embodiment Construction

[0027] Such as figure 2 and image 3 As shown, in one embodiment of the reflector of the present invention, the reflector 100 is roughly in the shape of an oblique quadrangular pyramid whose apex is cut off. offset, see figure 1 , the apex 3 of the oblique pyramid 1 is offset to one side, and the apex 2 is removed by oblique cutting. The shape of the reflector 100 is roughly the same as that of an oblique quadrangular pyramid with the vertex 2 cut off. The edge of the opening of the reflector 100 extends a roughly circular end face 180, on which a connecting hole is provided for installation in an application. The end face 180 It is not essential, and its shape can also be various.

[0028] The reflector 100 includes a bottom surface 110, and a first reflective surface 120 connected to the bottom surface 110, a second reflective surface 130, a third reflective surface 140 and a fourth reflective surface 150, wherein the second reflective surface 130 and the third light-emi...

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.

Description

technical field [0001] The invention relates to a tunnel lighting fixture, more specifically, to a reflector and a tunnel lamp using the reflector. Background technique [0002] In recent years, with the rapid development of semiconductor technology and lighting technology, the technical level of LED lights has made a breakthrough. Compared with traditional light sources, LED lights have the advantages of low energy consumption and long life. As a new type of light source, LED lamps have widely replaced incandescent lamps that are fragile, short in life, and high in energy consumption in many occasions. [0003] Due to the small size of the LED lamp, the light irradiation range after it emits light is relatively small. Using a single LED lamp as a lamp lighting is not suitable for some occasions with relatively high lighting requirements, such as dark and narrow tunnel environments; in addition, currently Generally, a conical reflector is used to reflect the light emitted ...
