Abstract
The utility model discloses a reflection cup with good light distribution performance. The whole reflection cup is formed by a curved wire wound around a perpendicular central axis of the center of the lower end of the reflection cup. The cross section of the reflection cup is gradually increased from the lower end of the reflection cup to the upper end of the reflection cup. A plurality of hollow light permeable holes are formed in the cup wall close to the upper end of the reflection cup in the circumferential direction. The hollow light permeable holes are formed in the cup wall close to the upper end of the reflection cup in the circumferential direction, so that the light distribution performance of an LED is further optimized, part of light of an LED light source outside the reflection cup is reflected, part of light is transmitted, and therefore the light intensity of the LED light source in each direction is more even. Meanwhile, the effect that the surface brightness of a bulb shell or a lampshade possibly arranged outside is more even is achieved.
Description
Technical field
The utility model relates to the LED lighting technical field, particularly the good reflector of a kind of luminous intensity distribution performance.
Background technology
General LED bulb lamp is difficult to accomplish wide-angle, and its cell-shell is semicircle, so angle is no more than 200 ° substantially.
Now some relatively noveler designs are Polyhedral pedestals that a protrusion is set at radiator, and LED lamp pearl is attached on the aluminium lamp plate more than three or three, the aluminium lamp plate is fitted on the different lateral of Polyhedral pedestal again.Although this design can be done angle greatly, will be poor aspect heat radiation, general LED bulb lamp is little because it dispels the heat sectional area ratio; Making in addition a plurality of aluminium lamp plates, can increase material cost, also can increase assembly difficulty at assembling stage, also is to have increased cost of labor.
Ad hocly want to design a kind of Novel LED light, at a lamp plate reflector to be set, and being equipped with led light source on the inside and outside lamp plate of reflector, the light that the led light source of reflector inside sends reflects, reflects through the reflector inner surface, makes the increase rising angle; The light that the led light source of outside, reflector lower end sends reflects, reflects through the reflector outer surface, makes the increase rising angle; Thereby LED lamp that wide-angle is luminous of whole formation; But because if there are cell-shell or lampshade in the reflector outside, on some specific cell-shells or lampshade, although the distribution curve flux of lamp is no problem, may produce a circle dark space on cell-shell or the lampshade, brightness irregularities, thus can affect illumination effect.
The utility model content
The utility model provides a kind of light source utilization rate height, has eliminated the dark space, has made the uniform reflector of surrounding brightness for above-mentioned the deficiencies in the prior art.
The technical solution of the utility model is achieved in that
The reflector that a kind of luminous intensity distribution performance is good, described reflector integral body is to be rotated a circle around a vertical center axis through center, reflector lower end by a curve to form, by the reflector lower end to the upper end, the cross-sectional area of reflector increases gradually, on the wall of cup of the close upper end of reflector along the loophole that circumferentially has a plurality of hollow outs.
As preferably, the upper end open of reflector or lens are housed in the reflector upper end, the lower ending opening of reflector or lens are housed in the reflector lower end.Can further install according to actual needs lens additional, increase lighting angle.
As preferably, described loophole is diamond hole or elliptical aperture or trapezoidal hole.
As preferably, the cross section of reflector is circular.
Adopted design philosophy of the present utility model and the beneficial effect of technique scheme to be:
Reflector of the present utility model is through rational curve setting so that the realization that the inside and outside led light source of reflector all can maximum angle luminous with reflection, refraction, improved the efficient of light fixture.
Moreover, on the wall of cup of the close upper end of reflector, along the loophole that circumferentially has a plurality of hollow outs, can further optimize like this luminous intensity distribution performance of LED, make the part light reflection of reflector external LED light source, the transmission of part light makes led light source more even in the light intensity of all directions.The cell-shell that may arrange or the more uniform effect of lampshade surface brightness that make the outside are also arranged simultaneously.
Description of drawings
Fig. 1 is the perspective view of reflector among the embodiment 1;
Fig. 2 is the use state diagram of embodiment 1 reflector;
Fig. 3 is the perspective view of reflector among the embodiment 2.
The specific embodiment
The specific embodiment of the present utility model is as follows:
Embodiment 1: the reflector that a kind of luminous intensity distribution performance is good, as shown in Figure 1, 2, described reflector 7 integral body are to be rotated a circle around a vertical center axis through center, reflector 7 lower end by a curve to form, by reflector 7 lower ends to the upper end, the cross-sectional area of reflector 7 increases gradually, on the wall of cup of the close upper end of reflector 7 along the loophole 16 that circumferentially has a plurality of hollow outs.The purpose of loophole is set, and is the luminous intensity distribution performance for the further LED of optimization, makes the part light reflection of reflector external LED light source, and the transmission of part light makes led light source more even in the light intensity of all directions.The cell-shell that may arrange or the more uniform effect of lampshade surface brightness that make the outside are also arranged simultaneously.The loophole 16 of present embodiment is diamond hole.
Embodiment 2: the difference of present embodiment and embodiment 1 is that as shown in Figure 3, loophole 16 is up big and down small trapezoidal hole.
Claims (4)
1. reflector that luminous intensity distribution performance is good, it is characterized in that: described reflector integral body is to be rotated a circle around a vertical center axis through center, reflector lower end by a curve to form, by the reflector lower end to the upper end, the cross-sectional area of reflector increases gradually, on the wall of cup of the close upper end of reflector along the loophole that circumferentially has a plurality of hollow outs.
