Abstract
A semiconductor light-emitting device comprises a lamp head, a lamp seat, a reflection cup, light-emitting diode (LED) bulbs and a lampshade, the reflection cup is arranged on the upper potion of the lamp seat inside the lampshade, the reflection cup is a hollow cone frustum, and comprises an inner reflective face and an outer reflective face. The LED bulb is arranged at the outer side of the outer reflective face, the LED bulb is arranged at the inner side of the inner reflection cup, and the LED bulbs are arranged in the same plane. The diameter of a circular cross section at the upper end portion of the reflection cup is larger than the diameter of a circular cross section at the lower end portion of the reflection cup. The diameter of the circumference of the LED bulb is larger than or equal to the diameter of the circular cross section of the upper end portion of the reflection cup. Due to the fact that the semiconductor light-emitting device comprises two reflection faces, utilization rate of the light source is improved, illumination brightness and uniformity of light are improved, illuminating angle is increased, illumination dark space is reduced, and the illuminating effect of the front end of a lamp is improved in a large range.
Description
Technical field
The utility model relates to a kind of light fixture, specifically, relates to a kind of semiconductor light-emitting apparatus.
Background technology
At present, common LED lamp on the market, major part all is the lighting angle that utilizes LED lamp pearl self luminous intensity distribution to design, usually between 120～140 degree.When such LED lamp uses, then can form the dark space in big zone in floodlight type light fixture, influence the illuminating effect that light fixture reaches.
Chinese patent, application number are 201220221855.3, and name is called the LED lamp and discloses a kind of LED lamp, comprise the reflector of LED and positive terrace with edge shape; The bottom surface length of side of reflector is less than the upper bottom surface length of side; LED is positioned on the plane at bottom surface place of reflector, can the light that LED sends be reflected, and increases the lighting angle of LED lamp, reduces the scope of dark space.But in actual use, because the existence of reflector, the dead ahead brightness of lamp is not enough, influences illuminating effect.
The utility model content
At above-mentioned deficiency of the prior art, it is a kind of simple in structure that the utility model provides, and has the reflector of two reflective surfaces, can dwindle the light-illuminating dark space, guarantees that simultaneously the dead ahead of lamp has the semiconductor light-emitting apparatus of enough brightness.
Technical solution adopted in the utility model is:
A kind of semiconductor light-emitting apparatus comprises: lamp holder, lamp socket, reflector, LED bulb and lampshade, and described lampshade inside, the lamp socket top is provided with reflector, and described reflector is the frustum of a cone of hollow, has interior reflective surface and outer reflective surface; Described outer reflective surface arranged outside has LED bulb, interior reflective surface inboard to be provided with the LED bulb.
Described LED bulb is arranged on same plane.
Cross section, described reflector upper end diameter of a circle is greater than cross section, bottom diameter of a circle: described LED bulb is along the circumference setting; The circle diameter of the described LED bulb that is arranged on the outer reflective surface outside is more than or equal to cross section, reflector upper end diameter of a circle.
The beneficial effect of the relative prior art of the utility model:
The utility model semiconductor light-emitting apparatus, reflector have the utilization rate that two reflective surfaces had both improved light source, have improved the uniformity of irradiation brightness and light, have improved irradiating angle again, have reduced the irradiation dark space, have improved illuminating effect.

Fig. 1 is the structural representation of a kind of embodiment of the utility model semiconductor light-emitting apparatus;
Fig. 2 is the perspective view of the utility model semiconductor light-emitting apparatus reflector.
Critical piece symbol description in the accompanying drawing:
Among the figure:
1, lamp holder 2, lamp socket
3, LED bulb 4, outer reflective surface
5, interior reflective surface 6, lampshade
7, reflector.
The specific embodiment
Followingly with reference to drawings and Examples the utility model is described in detail:
Attached Fig. 1 and 2 as can be known, a kind of semiconductor light-emitting apparatus comprises: lamp holder 1, lamp socket 2, reflector 7, LED bulb 3 and lampshade 6, described lampshade 6 inside, lamp socket 2 tops are provided with reflector 7, and described reflector 7 is the frustum of a cone of hollow, have interior reflective surface 5 and outer reflective surface 4; Described outer reflective surface 4 arranged outside have LED bulb 3, interior reflective surface 5 inboards to be provided with LED bulb 3; Described LED bulb 3 is arranged on same plane; Cross section, described reflector 7 upper end diameter of a circle is greater than cross section, bottom diameter of a circle; Described LED bulb 3 is along the circumference setting; The circle diameter of the described LED bulb 3 that is arranged on outer reflective surface 4 outsides is more than or equal to cross section, reflector 7 upper end diameter of a circle.
The utility model semiconductor light-emitting apparatus, reflector has the utilization rate that two reflective surfaces had both improved light source, improved the uniformity of irradiation brightness and light, improved irradiating angle again, reduced the irradiation dark space, the circle diameter of the LED bulb in the outer reflective surface outside makes the illuminating effect of light fixture front end be greatly improved more than or equal to cross section, reflector upper end diameter of a circle.
