Abstract

The utility model provides a light-emitting diode (LED) light reflector which comprises a reflector frame, and a reflector curved surface. A plurality of transverse and longitudinal grooves is on the reflector curved surface. The LED light reflector adopts the material of metal aluminum, has the advantages of thermostability, good heat dispersion, low cost, insulation after oxidation. The LED reflector with the parabolic surface design, effectively reduces the light loss, astigmatism and glaring. The design of the LED light reflector is novel, unique, simple and practical. In this way, the power and life of the LED is improved.

Description

A kind of LED reflective optical system

Technical field

The utility model relates to a kind of reflector, particularly a kind of LED reflective optical system.

Background technology

The operation principle of LED lamp is so that become very outstanding in high-power LED illumination industry heat dissipation problem, many LED illumination schemes are paid little attention to heat radiation, or technical merit is limited, so the high-powered LED lamp ubiquity of volume production is nothing like theoretical value actual life at present, cost performance is lower than the awkward situation of conventional lamp.

Nowadays in the high-power LED lamp on the market, because utilizing lens as the medium of secondary optics luminous intensity distribution in its light source, do not reach the specific illumination demand of high-power LED lamp far away, example: the bulkhead lamp capable that adopts the LED high power light source, street lamp, bulkhead lamp capable just need have optically focused and two kinds of lighting demands of floodlight because of its working environment, the lighting demand of street lamp then is as main take optically focused, common light source utilizes the secondary optics luminous intensity distribution to adopt lens can reach the lighting demand of floodlight, the lighting demand of optically focused then needs another kind of medium to cooperate the lens in the secondary optics luminous intensity distribution to use, therefore, our high-power LED light source has added this medium of reflective optical system, reaches specific spotlighting demand.

The utility model content

For addressing the above problem, the utility model designs a kind of LED reflective optical system, adopts the metallic aluminium material, have high temperature resistant, thermal diffusivity good, cost is low, plays insulating effect through oxidation, the LED reflective optical system adopts the parabolic surface design, effectively reduce light loss, reduced astigmatism, dazzled light.

The utility model provides a kind of LED reflective optical system, comprises the reflector frame and is connected to reflector curved surface on the reflector frame, on the described reflector curved surface many transverse grooves and cannelure is arranged.

As further improvement of the utility model, described cannelure radially.

As further improvement of the utility model, described transverse groove forms a plurality of concentric circles, and circumference increases gradually from inside to outside.

As further improvement of the utility model, the angle of described reflector curved surface and horizontal plane is 15 °-20 °.

As further improvement of the utility model, the angle of described reflector curved surface and horizontal plane is 18 °.

As further improvement of the utility model, described reflector curved surface is parabolic type.

The beneficial effects of the utility model are:

1, reflective optical system adopts the metallic aluminium material, have high temperature resistant, thermal diffusivity good, cost is low, plays insulating effect etc. through peroxidating.

2, adopt the parabolic surface design, effectively reduce light loss.

3, on the reflector curved surface many transverse grooves and cannelure are arranged, can play better optically focused effect.

4, this structure decrease the astigmatism, dazzle light, novel in design, unique, simple and practical, power and the life-span that can improve LED.
