Abstract

The utility model relates to the illumination field and provides an LED luminaire. The LED luminaire comprises a lamp body and a lampshade arranged on the lamp body, wherein the lampshade is internally provided with a PCB; the PCB is provided with a plurality of LED light sources; and a reflecting cover which can reflect and refract the light beams emitted by the LED light source is arranged above the LED light source. In the utility model, the reflecting cover which can reflect and refract the light beams emitted by the LED light source is arranged above the LED light source; after the LED light source emits the light beam, the light beam is reflected and refracted by the reflecting cover and enters the lampshade, thus playing the illumination function; as the reflecting cover is arranged above the LED light source, on the one hand, the light outlet surface of the light beam is enlarged so that the light is distributed more uniformly; simultaneously the LED light source is avoided to be directly exposed in the lampshade and the dizzy phenomenon is avoided; and the flexibility and uniformity of the light beam are improved effectively, and the illumination effect is improved.

Description

The LED light fixture
Technical field
The utility model belongs to lighting field, relates in particular to a kind of LED light fixture.
Background technology
Early former LED is just to be widely applied to light current fields such as signal indication, digital demonstration in extremely low power consumption, extraordinary service life.Nowadays along with the succeeding in developing of ultra-high brightness LED, just make it be used in more and more that color lamp is decorated, lighting field, LED is convenient to coordinate control with it, color is pure, the optical efficiency height, caloric value is low etc., and advantage replaces the traditional lighting light source gradually, obtains insider's common concern.
Consult Fig. 1, Figure 1 shows that the structure chart of existing LED light fixture, this LED light fixture generally comprises lamp body 91, printing opacity cover 92 and pcb board 93, and pcb board 93 is provided with the led light source 94 after some encapsulation, is emitted beam by led light source 94, realizes the effect of illumination.Though existing this LED light fixture is more common, all be directly luminous by led light source 94, realize illuminating effect, because light is directly to send by led light source 94, light is of poor quality, can produce dazzle, dazzling phenomenon.
The utility model content
Technical problem to be solved in the utility model be to provide a kind of light evenly soft, can not produce the LED light fixture of dazzle.
The utility model is such realization, a kind of LED light fixture comprises lamp body and is located at lampshade on the described lamp body, is provided with pcb board in the described lampshade, described pcb board is provided with some led light sources, and described led light source top is provided with the reflector that can reflect and reflect the light that this led light source sends.
Particularly, described reflector is made by transparent optical plastic or optical glass.
More specifically, the cross section of the reflecting surface of described reflector is a back taper, or for the place, summit is provided with the back taper of epirelief circular arc line, or be waveform.
Further, the reflecting surface of described reflector is provided with the point-like of hot pressing or injection mo(u)lding or the reticulate structure of strip, and described reticulate structure from top to bottom density successively decreases gradually and is arranged in array-like.
Particularly, described lampshade is made by transparent optical plastic or optical glass.
Particularly, described lamp body is made by engineering plastics.
Further, described lamp body surface offers some grooves.
Particularly, described groove is a strip groove, and described groove is symmetrical arranged on described lamp body.
The utility model is provided with the reflector that can reflect and reflect the light that led light source sends above led light source, after led light source emits beam, enter in the lampshade after reflector reflection and refraction, thereby play the effect of illumination; Owing to above led light source, be provided with reflector, enlarged the exiting surface of light on the one hand, make distribution of light more even, simultaneously, avoid led light source directly to expose in lampshade and the glare phenomenon that causes, improved the soft property and the uniformity of light effectively, improved illuminating effect.
Description of drawings
Fig. 1 is the structural representation of the LED light fixture that provides of prior art;
Fig. 2 is the schematic diagram of the LED light fixture with conical reflector that provides of the utility model embodiment;
Fig. 3 is the schematic diagram of the LED light fixture of summit place that the utility model embodiment the provides back taper that is provided with the epirelief circular arc line;
Fig. 4 is the schematic diagram of the LED light fixture with waveform reflector that provides of the utility model embodiment;
Fig. 5 is the schematic diagram that the reflecting surface of the reflector in Fig. 2 is provided with the reticulate structure of point-like.
The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
As Fig. 2~shown in Figure 4, a kind of LED light fixture that the utility model embodiment provides, comprise lamp body 1 and be located at lampshade 2 on the lamp body 1, be provided with pcb board 3 in the lampshade 2, pcb board 3 is provided with some led light sources 4, and led light source 4 tops are provided with the reflector 5 that can reflect and reflect the light that this led light source 4 sends.After led light source 4 emits beam, after reflector 5 reflection and refraction, enter in the lampshade 2, thereby play the effect of illumination; Owing to above led light source 4, be provided with reflector 5, enlarged the exiting surface of light on the one hand, make distribution of light more even, simultaneously, avoided led light source 4 directly to expose in lampshade 2 and the glare phenomenon that causes, improve the soft property and the uniformity of light effectively, improved illuminating effect.
Particularly, reflector 5 is made by transparent optical plastic or optical glass, as materials such as PC, PMMA.The cross section of the reflecting surface of reflector 5 is turbination (as shown in Figure 2) or waveform (as shown in Figure 4), or be provided with the back taper (as shown in Figure 3) of epirelief circular arc line for summit place, perhaps other have the shape of reflection and refracted ray, and the light that the reflecting surface of these shapes can send led light source 4 well reflects and reflects.
As Fig. 2 and shown in Figure 5, further, the reflecting surface that reflector 5 is is provided with the point-like (as shown in Figure 5) of hot pressing or injection mo(u)lding or the reticulate structure of strip, and reticulate structure from top to bottom density successively decrease gradually and be arranged in array-like.By the reflecting surface at reflector 5 reticulate structure of point-like or strip is set, can reflects the light of led light source 4 better, light is shone to all directions, that the light that sends becomes is even, soft, illumination zone is wide; And why with reticulate structure from top to bottom density arrange decreasingly, be because the density of the light of led light source 4 reduces under last gradually along reflector 5, the light that led light source 4 is sent becomes more even, soft after reflector 5 reflections or refraction.
Particularly, lampshade 2 is also made by transparent optical plastic or optical glass, and lampshade 2 not only plays the effect of protection internal components, can also play the dustproof effect; And transparent housing 2 is made different profiles, as spheroidal, oval spherical or other shapes, can play the effect that beautifies, intersperses surrounding environment.
