Abstract

The utility model discloses a polarization LED desk lamp reflector, which comprises a reflector substrate. The reflector substrate is arranged symmetrically relative to a transverse symmetric surface thereof; the curved surface of the transverse end of the reflector substrate extends outwards, and the other transverse end of the reflector substrate is provided with two reflective concave shell surfaces which are arranged symmetrically relative to the transverse symmetric surface. The utility model can guide the light beams emitted by a light source, and when the desk lamp is used, the user is not required to lift the elevation of the lamp head so as to obtain the radiation area of polarized light. Moreover, the light beams in the concave shell surfaces can be guided to the extended curved surface, thereby concentrating the light beams on the working area of the desk lamp, strengthening the brightness of the radiation area, preventing the unnecessary light pollution, improving the lighting efficiency of the light source, and realizing the purpose of energy conservation, glare prevention, eye protection and reduction of light pollution.

Description

Polarized light type LED desk lamp reflector

Technical field

The utility model relates to a kind of lighting apparatus, is specifically related to a kind of polarized light type LED desk lamp reflector.

Background technology

The kind of desk lamp is more and more, and when desk lamp being carried out the light optics design, existing design is that irradiation area is enlarged, and is the center with the light fixture light-emitting window, forms an axisymmetric irradiation area.But in actual use, the real work zone of read-write desk lamp is asymmetric, and it requires with the light fixture light-emitting window is the center, forms the function illumination to operative orientation 120 degree subtended angle directions.A kind of so actual requirement of using and the difference of design have caused the low of light utilization efficiency, cause light pollution.Also there is part producer to recognize this problem, by the mode at the change lamp holder elevation angle, the working region of realizing accent light, but consequence causes serious glare exactly, and human eye has been caused serious injury.

LED has characteristics such as energy-conservation, no mercury, environmental protection as the solid luminescent light source of a new generation, replaces traditional incandescent lamp, fluorescent lamp just gradually, becomes the light source of new generation of illumination.And at present on the LED light fixture, most outward appearance, performances of just in form LED being made conventional light source are substituted, and have but lost characteristics and the advantage of LED itself.

The utility model content

Technical problem to be solved in the utility model provides a kind of polarized light type LED desk lamp reflector, and it does not need the people to raise the irradiation area that the lamp holder elevation angle can obtain polarisation, and can strengthen the brightness of irradiation area.

For solving the problems of the technologies described above, the technical solution of the utility model polarized light type LED desk lamp reflector is:

Comprise the reflector matrix, described reflector matrix is symmetrical with respect to its lateral symmetry face; The curved surface of the horizontal end of reflector matrix outwards stretches, and the horizontal other end of reflector matrix is provided with two the reflection concave housing surfaces symmetrical with respect to the lateral symmetry face.

The lateral dimension of the end face outline line of described reflector matrix is greater than longitudinal size.

Described reflector matrix adopts efficient reflectance coating or aluminium.

The intersection of described two reflection concave housing surfaces is a straight line.

Described reflector matrix bottom is provided with position, led light source hole.

The technique effect that the utility model can reach is:

The light channeling conduct that the utility model can send light source does not need the people to raise the irradiation area that the lamp holder elevation angle can obtain polarisation when using desk lamp; And the curved surface of the horizontal end of reflector matrix outwards stretches; laterally the other end is provided with the reflection concave housing surface; the reflector of this shape can be directed to the light in concave housing surface zone the stretching, extension curvature portion; thereby light is focused on the working region of desk lamp; strengthen the brightness of irradiation area; avoid unnecessary light pollution, improve the illumination utilization rate of light source, realize the purpose of energy-conservation, anti-dazzle eyeshield, minimizing light pollution.
