Abstract

The invention discloses an LED illumination light distribution system comprising a first light reflecting surface, an LED luminophor arranged at the bottom of the first light reflecting surface and a second light reflecting surface which is arranged in the first light reflecting surface and opposite to a first light reflecting cup. The direct light of an LED can be distributed through the second light reflecting surface can be distributed and reflected out of the first light reflecting surface, thus, more rays can be controlled in an effective solid angle to generate a required light distribution effect.

Description

A kind of LED illuminating light distribution system
Technical field
The present invention relates to a kind of LED illuminating light distribution system.
Background technology
The LED lighting generally adopts single reflective surface to carry out luminous intensity distribution at present.Because the bright dipping of LED illuminator has directionality, perpendicular to the light of LED illuminator exiting surface, can't all reflect via a reflective surface, reaches required light distribution effect.
Summary of the invention
The technical problem that the present invention will solve provides a kind of LED luminous intensity distribution scheme of optimization, and control LED goes out light path, produces required light distribution effect.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: comprise first reflective surface, and be arranged on the LED illuminator in first reflective surface, and be arranged on second reflective surface in first reflective surface, that be oppositely arranged with first reflective surface.
Further, said second reflective surface is positioned on the LED illuminator light direction.
Further, said first reflective surface and second reflective surface are the curved surface setting.
LED illuminating light distribution of the present invention system owing to can the direct light of LED illuminator be distributed through second reflective surface, penetrates from the reflection of first reflective surface, can more light be controlled in the effective solid angle, produces required light distribution effect.
Description of drawings
Fig. 1 is the sketch map of LED illuminating light distribution of the present invention system.
The specific embodiment
In the present embodiment, with reference to shown in Figure 1, this LED illuminating light distribution system comprises first reflective surface 1, and is arranged on the inner LED illuminator 2 of first reflective surface 1, and is arranged on second reflective surface 3 in first reflective surface 1, that be oppositely arranged with first reflective surface 1.Can more light be controlled in the effective solid angle, reach required light distribution effect.
Wherein, said second reflective surface 3 is positioned on the light direction of LED illuminator 2.Said first reflective surface 1 and second reflective surface 3 are the curved surface setting, can more light be controlled in effective solid angle, reach required light distribution effect.
LED illuminating light distribution of the present invention system owing to can the direct light of LED be distributed through second reflective surface, penetrates from the reflection of first reflective surface, can more light be controlled in the effective solid angle, reaches required light distribution effect.
Below the present invention is done a detailed description, the above is merely the present invention's preferred embodiment, when can not limiting practical range of the present invention, promptly allly does impartially to change and modify according to the application's scope, all should still belong in the covering scope of the present invention.
