The invention relates to a LED lighting device, with high utilization, energy saving and high strength of effective light, wherein said device comprises a LED lamp (1) and a reflective focus plate (2); said plate is formed by at least one reflective curvature; the number of LED lamp is relative to the number of reflective curvature and distributed on the focus of reflective curvature; the light of LED lamp (1) is fully reflected by the reflective focus plate (2). The invention has wider application.
Description
Technical field
The present invention relates to a kind of LED light-emitting apparatus.
Background technology
Now the LED lamp obtains people's trust with high brightness, low energy consumption, long-life premium properties, and also in constantly widely further investigation, the performance of LED lamp is also in continuous distillation about the physical property of LED.But prior art is just improved the performance of LED lamp itself, and the light that the LED lamp sends only is utilized by the lighting angle that itself is fixed, and do not pass through effective optically focused or luminous intensity distribution, so its light that sends can not be fully utilized.So prior art exists not enough: the utilization rate of light is low, and is not energy-conservation, effectively light intensity is low.
Summary of the invention
Technical problem to be solved by this invention is the deficiency that overcomes on the prior art, and a kind of utilization rate height of light, the LED light-emitting apparatus that energy-conservation, effective light intensity is high are provided.
The technical solution adopted in the present invention is: the present invention includes the LED lamp, it also comprises light reflecting and concentrating panel, described light reflecting and concentrating panel is made up of a slice or the above reflective surface of a slice, the corresponding quantity with described reflective surface of the quantity of described LED lamp is identical and be separately positioned on the focus of described reflective surface, and the light that described LED lamp sends is through described light reflecting and concentrating panel total reflection.
Described reflective surface is parabola or ellipsoid.
The present invention also comprises light distributing cap, and described light distributing cap is arranged on the place ahead of described light reflecting and concentrating panel and described LED lamp or is arranged on the reflecting surface of described light reflecting and concentrating panel.
The invention has the beneficial effects as follows: because the present invention is provided with light reflecting and concentrating panel, described LED lamp is arranged on the focus of described light reflecting and concentrating panel, the light that described LED lamp sends is through described light reflecting and concentrating panel total reflection, and shoot out with little angle of embrace illumination, can not weaken and light intensity because of the lighting angle of described LED lamp, form by a slice or the above reflective surface of a slice owing to light reflecting and concentrating panel of the present invention again, so brightness that can be as required, the LED lamp of varying number is set, to reach required brightness, so the utilization rate height of light of the present invention, energy-conservation, effective light intensity height.
Because the present invention also is provided with light distributing cap, can design different light distributing caps as required, the needs with the irradiation area that satisfies difformity and area satisfy different illuminations and semaphore request, so the present invention can make full use of effective light, the utilization rate height.
Because reflective surface of the present invention is parabola or ellipsoid or other curved surface, so moulding of the present invention is simple, style is many.
Because the present invention adopts the LED lamp as light source, so long service life of the present invention.

The specific embodiment
Embodiment one:
As shown in Figure 1, the present invention includes LED lamp 1, light reflecting and concentrating panel 2, described light reflecting and concentrating panel 2 is made up of the parabolic reflective surface of a slice, described LED lamp 1 is positioned on the paraboloidal focus, the light that described LED lamp 1 sends reflects away through described light reflecting and concentrating panel 2 horizontal parallel, and the light that described LED lamp 1 sends forms the column light source after reflection, and is stronger at effective regional luminance, outrange, can be used for flashlight.
Embodiment two:
As shown in Figure 2, the present invention includes LED lamp 1, light reflecting and concentrating panel 2, described light reflecting and concentrating panel 2 is made up of a slice ellipsoid reflective surface, described LED lamp 1 is positioned on the focus of ellipsoid, the light that described LED lamp 1 sends reflects away through the convex lens horizontal parallel after described light reflecting and concentrating panel 2 focuses on again, and the light that described LED lamp 1 sends forms spot light after the ellipsoid reflection, and spot light planoconvex lens again reflects into directional light, therefore in that effectively regional luminance is stronger, can be used for auto lamp.
Embodiment three:
As shown in Figure 3, present embodiment is on embodiment one or two basis, light reflecting and concentrating panel 2 is divided into four curved surfaces, the shape of each curved surface is made up of different ellipsoids parabolic or different sizes respectively, corresponding LED lamp 1 has four and be arranged on the focus place of each curved surface, has so more strengthened the brightness of bright dipping.
Embodiment four:
As shown in Figure 4, present embodiment is to have set up light distributing cap 3 on embodiment one or two basis, and the light that LED lamp 1 sends forms the transmitting illuminant corresponding with reflecting surface after reflection, again through light distributing cap 3 luminous intensity distributions, the direction of illumination and the zone of light are changed, reach instructions for use.
Embodiment five:
As shown in Figure 5, present embodiment also is to have set up light distributing cap 4 on embodiment one or two basis, just on the reflective surface of light distributing cap 4 attached to light reflecting and concentrating panel 2, need light distributing cap be set in light reflecting and concentrating panel 2 fronts, saves space and cost.
Embodiment six:
Present embodiment is to have set up light distributing cap 3 on the basis of embodiment three, and the light that LED lamp 1 sends forms the transmitting illuminant corresponding with reflecting surface after reflection, again through light distributing cap 3 luminous intensity distributions, makes the light distribution of light source satisfy actual instructions for use.
Embodiment seven:
Present embodiment is to have set up light distributing cap 4 on the basis of embodiment three, just on the reflective surface of light distributing cap 4 attached to light reflecting and concentrating panel 2, saves space and cost.
Certainly, light reflecting and concentrating panel 2 of the present invention also can adopt the high-order curved surface that curvature is different everywhere.
The present invention can be widely used in throwing light on, the place of signal and light indication.
