Abstract

The utility model relates to a lamp cover for LBD, comprising a reflector and a circuit board. The reflector is provided with a concave groove and the opposite wall surface of the concave groove is the reflecting side. The circuit board and the reflector are overlapped with each other. A LBD is arranged fixedly on the circuit board opposite to the concave groove, and the LBD extends into the concave groove. When the LBD lights, the reflect side can reflect the light, so that the LBD with single light source has a plurality of light shadows, thereby changing the light of the LBD from spot light source into side light source, and increasing the density of light source under fixed light source, further increasing the brightness of the LBD.

Description

Use the lampshade of light emitting diode

Technical field

The utility model is a kind of lampshade that uses light emitting diode, provide a kind of can be with the light that light emitting diode sent, and spot light is changed into the lampshade structure of area source.

Background technology

Traditional tengsten lamp, the light that it sent is to be scattering state, thus can throw light on to the brightness that its context produces to a certain degree, but traditional tengsten lamp has the shortcoming of power consumption, in view of this, the light emitting diode with power saving just replaces traditional tengsten lamp gradually.

Yet the light that existing light emitting diode sent is to be linearity, so this light is can not be dispersion shape, light is to converge at a place, the luminance shortage so the context of non-light emitting diode light line junction will seem.

Summary of the invention

Because the inconvenience on the aforesaid prior art, the utility model is a kind of lampshade that uses light emitting diode of design, provide a kind of reflective surface that has, and the light that light emitting diode is sent is the lampshade structure of dispersion shape.

For achieving the above object, the technological means that the utility model adopted is a kind of lampshade that uses light emitting diode of design, it has circuit board, light emitting diode and refractive body, light emitting diode is the end that is welded in circuit board, refractive body is to pile up mutually with circuit board to combine, refractive body is formed with groove with respect to the light emitting diode position of circuit board, and the opposed inner walls face of groove is to be reflective surface, and being formed with in the bottom face of groove in addition can be for the perforation that light emitting diode ran through.

As above-mentioned structure, when lumination of light emitting diode, reflection by reflecting surface, and make the light emitting diode of single light source have a plurality of shadows, make the light that light emitting diode sent change area source into by this, therefore, under fixed light source, can increase light source density by spot light, and form comprehensive light source, and then increase the brightness that light emitting diode sent.

The specific embodiment

The utility model is a kind of lampshade that uses light emitting diode, please cooperate with reference to (it is to represent for the utility model is 180 drawings of spending counter-rotating) shown in Fig. 1-2, and it has circuit board 10, light emitting diode 11 and refractive body 12;

Light emitting diode 11, it is the end that is welded in circuit board 10;

Refractive body 12, its light emitting diode 11 positions with respect to circuit board 10 are formed with groove 13, please cooperate with reference to shown in Figure 3, groove 13 is to be rectangular arrangement, please cooperate with reference to it is to represent for the utility model is 180 drawings of spending counter-rotating shown in the 4th figure, the opposed inner walls face of groove 13 and bottom face are to be reflective surface 131, bottom face in groove 13 is formed with the perforation 132 that can supply light emitting diode 11 to be run through in addition, when refractive body 12 and circuit board 10 are when piling up shape and combining, light emitting diode 11 is able to extend in the groove 13 via perforation 132.

So when light emitting diode 11 produced lights, this light can be via the reflection of each reflective surface 131 of groove 13, and this light is formed with as dispersion shape, the environment arround illuminating by this.

Comprehensively above-mentioned, reflection by reflecting surface 131, make the light emitting diode 11 that only can send single light source have a plurality of shadows, and make light emitting diode 11 change area source into by spot light, so under fixed light source, can increase light source density, and form comprehensive light source, and then increase the brightness that light emitting diode 11 is sent.

Please cooperate with reference to shown in the figure 5-8, it is to be another embodiment of the utility model, present embodiment is that the circuit board 10 of first figure, light emitting diode 11 are further derived with the installing mode of refractive body 12, in present embodiment, it has housing 20, circuit board 21, light emitting diode 22 and refractive body 23;

Housing 20 please cooperates with reference to shown in figure 6 and 8 again, and it is formed with tank 201, and the wall of tank 201 is to be reflective surface 202, and housing 20 is connected with vertical rod 203, and vertical rod 203 can be arranged at the appropriate position with housing 20;

Circuit board 21, light emitting diode 22 and refractive body 23, its compound mode,, can be placed in this combination in the tank 201 of housing 20 after circuit board 21, light emitting diode 22 are finished with the combination of refractive body 23 so do not give unnecessary details as aforementioned.

When light emitting diode 22 sends light, this light can reflect via the reflective surface 232 of the groove 231 that refractive body 23 was provided with and the reflective surface 202 of tank 201 respectively, and the spot light that makes light emitting diode 22 be sent forms area source, the environment arround this light is illuminated by this.
