Abstract
The invention discloses an LED module capable of emitting rectangular spots. The LED module capable of emitting rectangular spots comprises a reflector substrate, a reflecting housing is arranged at the upper part of the reflector substrate, the reflector substrate is further provided with an LED lamp, the LED lamp is located in the reflecting housing, a central reflecting block used for deviating the central light of the LED lamp towards the two sides is arranged above the LED lamp, the central reflecting block is a transparent or semi-transparent central reflecting block, and the central reflecting block is located in the reflecting housing. The LED module capable of emitting rectangular spots enables the shape of the rectangular spots to be closer to rectangular shape, and the utilization efficiency is higher; the light spot uniformity is obviously improved, and the large-angle light spot effect and different-angle light spot effect can be realized.
Description
Technical field
The present invention relates to LED technology field, particularly a kind of LED module can launching rectangular light spot.
Background technology
Prior art provides LED module, and because most of LED central light strength is larger than other directions, the reflector that prior art provides can not redistribute the light at center, causes center illumination higher, when lighting angle requires larger, and the improvement poor effect of reflector.
Summary of the invention
The invention provides a kind of LED module can launching rectangular light spot, to make rectangular light spot shape closer to rectangle, utilization ratio is higher; The uniformity of hot spot significantly improves, and can realize the hot spot effect of wide-angle and different angles.
To achieve these goals, the invention provides following technical scheme:
A kind of LED module can launching rectangular light spot, it comprises: reflector pedestal, reflector pedestal, the top of described reflector pedestal is provided with the reflector of opening upwards, described reflector pedestal is also provided with LED, and described LED is positioned at described reflector, is provided with the foveal reflex block for being biased to both sides by LED central ray directly over described LED, described foveal reflex block is transparent or translucent foveal reflex block, and described foveal reflex block is positioned at described reflector.
Preferably, the lower end of described foveal reflex block is pointed head, and the upper end of described foveal reflex block is block, the arc joint face forming straight shape joint face between these top and bottom or concave.
Preferably, the centre of described reflector is horizontally set with a transparent bar, and described foveal reflex block is fixed on the below of described transparent bar.
Preferably, described reflector pedestal is provided with transparent reflective support body, described foveal reflex block is arranged on described reflective support body.
By implementing above technical scheme, have following technique effect: the LED module can launching rectangular light spot provided by the invention, to make rectangular light spot shape closer to rectangle, utilization ratio is higher; The uniformity of hot spot significantly improves, and can realize the hot spot effect of wide-angle and different angles, solves the problem of the wide-angle hot spot weak effect of conventional reflector.
Accompanying drawing explanation
The structural representation can launching the LED module of rectangular light spot that Fig. 1 provides for the embodiment of the present invention;
The structure can launching the LED module of rectangular light spot that Fig. 2 provides for the embodiment of the present invention and light path schematic diagram.
Detailed description of the invention
Technical scheme for a better understanding of the present invention, describes embodiment provided by the invention in detail below in conjunction with accompanying drawing.
The embodiment of the present invention provides a kind of LED module can launching rectangular light spot, as shown in Figure 1, it comprises: reflector pedestal 100, the top of described reflector pedestal 100 is provided with reflector 101, this reflector 101 opening upwards, for bowl-shape or other shapes, described reflector pedestal 100 is also provided with LED 103, described LED 103 is positioned at described reflector 101, general, this LED is positioned at the center of this reflector pedestal 100 and is positioned on the center line of reflector 101, foveal reflex block 104 is provided with directly over described LED 103, this foveal reflex block 104 is biased for the light that LED penetrated towards the center center line both sides to reflector 101, described foveal reflex block 104 is transparent or translucent foveal reflex block, the transparency of foveal reflex block 104 is adjusted according to the needs of the center brightness of emergent ray, described foveal reflex block 104 is positioned at described reflector 101.
As shown in Figure 2, the light that LED sends by foveal reflex block 104 is divided into four kinds:
1. the light that light 1:LED sends shines directly into target face after the reflection of reflector center reflex block;
2. the light that sends of light 2:LED arrives target illumination face through reflector center reflex block reflection back reflection to the interior reflective surface of reflector after SE secondary emission;
3. the light that light 3:LED sends shines directly into target face without reflector;
4. the light that light 4:LED sends is irradiated to target face after reflector inner surface primary event.
According to the shape need of the luminous situation of different LED and hot spot, the free form surface of adjustment foveal reflex block flexibly, and combine with the free form surface of the inwall of reflector, realize the illumination of uniform rectangular hot spot.In the middle of degree of understanding without being told on the low side time, the optical properties of center-adjustable reflex block: i.e. its reflection and ratio (reflect ratio generally comprises 50%-100%, but is not limited thereto interval) of transmission of adjustable, realizes Uniform Illumination.
Adopt the LED module can launching rectangular light spot that above-described embodiment provides, rectangular light spot shape is closer to rectangle, and utilization ratio is higher; The uniformity of hot spot significantly improves, and can realize the hot spot effect of wide-angle and different angles, solves the problem of the wide-angle hot spot weak effect of conventional reflector.
In the above-described embodiments, more specifically, the lower end of described foveal reflex block 104 is pointed head, and the upper end of described foveal reflex block is block, the arc joint face forming straight shape joint face between these top and bottom or concave.
In the above-described embodiments, more preferably, the centre of described reflector is horizontally set with a transparent bar 105, and described foveal reflex block is fixed on the below of described transparent bar.In other embodiments, also can arrange transparent reflective support body 106 separately on described reflector pedestal 100, described foveal reflex block is arranged on described reflective support body.Or reflective support body 106 adds that transparent bar 105 comes together to support this foveal reflex block,
Above a kind of LED module can launching rectangular light spot that the embodiment of the present invention provides is described in detail, for one of ordinary skill in the art, according to the thought of the embodiment of the present invention, all will change in specific embodiments and applications, in sum, this description should not be construed as limitation of the present invention.
