Abstract

The utility model discloses an improvement of a lighting device, comprising a condensation cage in spherical body with a light inlet hole and a light outlet hole, wherein a lighting unit is arranged in the light inlet hole and used for generating the emission ray and the inner spherical surface of the condensation cage is a light source reflection surface and the emission ray is reflected for one time or many times on the light source reflection surface to control the output beam at a certain light outlet angle, thus the light loss is effectively lost and the whole light outlet efficiency is effectively increased.

Description

The lighting device improvement

Technical field

The utility model relates to a kind of lighting device improvement, and particularly a kind of utilization is provided with a light hole at ball-type body reflector, makes light can be directed to suitable direction, so that the lighting device that whole light extraction efficiency effectively promotes.

Background technology

How general illumination Design of device direction is the direction of illumination of efficient guiding light source, and provide people comfort visually, for reaching the purpose of high efficiency irradiation (reducing stopping of light), lighting device has a reflector mostly, so that will be projeced into light guiding irradiation place on the reflector, be radiated at the light losing that non-predetermined illumination place causes to reduce light, so lighting device has a light shield to reduce the dazzling light of direct glare.

Please refer to Fig. 1, schematic diagram for a concentration structure of prior art, this light guide structure includes a lampshade 80 and is a trapezoidal shape, it is arranged at an illuminator 81 tops, wherein this lampshade 80 is bordering on illuminator 81 1 sides and offers a light in part 811, its opposite side then is a light out part 813, when illuminator 81 produces throw light, this throw light by this light in part 811 to be projected in the environment space, wherein this light in part 811 is an indentations, in order to incident ray after catadioptric, to increase the outgoing intensity of illumination.

See also Fig. 2, be the U.S. the 6th, 234, the disclosed a kind of White-light LED illumination of No. 645 patent cases system, this illuminator has lampshade 90 and at least three light emitting diodes 91, and each light emitting diode 91 sends the visible light with preset wavelength, and these lampshade 90 inwalls then are coated with layer of fluorescent powder, cause diffusion effect with light, reach the purpose of uniform light light emitting diode 91.

The light that yet the shortcoming of prior art is this lampshade only will throw on it passively produces diffusion, be not on one's own initiative light to be directed to suitable direction, so the utilization rate of its light is still on the low side, so this illuminator there is no remarkable efficacy aspect adjustment brightness part and the lifting light source utilization rate.

The utility model content

The purpose of this utility model is to provide a kind of lighting device improvement, wherein use diffusion and the principle of reflection of light in the ball-type body, make output beam can be controlled in certain rising angle and effectively reduction light loss, so make whole light extraction efficiency effectively promote.

Lighting device improvement described in the utility model, include a snoot, be a ball-type body, this snoot has an incidence hole and a light hole, this incidence hole is in order to settle a luminescence unit, and this luminescence unit penetrates light in order to produce one, and the Internal Spherical Surface of this snoot is a light source reflecting surface, this ejaculation light in the primary event of this light source reflecting surface or repeatedly reflection, is projected to environment space by this light hole via this at last.

Lighting device improvement described in the utility model can be directed to light suitable direction, therefore effectively improves brightness and effectively promotes the light source utilization rate.

The specific embodiment

Those skilled in the art below cooperate Figure of description that embodiment of the present utility model is done more detailed description, so that can implement after studying this specification carefully according to this.

Fig. 3 is the schematic perspective view of lighting device improvement described in the utility model.The utility model is relevant lighting device improvement, this lighting device includes a snoot 1 and a luminescence unit 3, this snoot 1 is a kind of spherical, its inside is a light source reflecting surface 11, this snoot 1 also has an incidence hole 13 and a light hole 15, this incidence hole 13 is in order to settle this luminescence unit 3, this luminescence unit 3 is in order to provide an incident ray, this luminescence unit 3 comprises a LED luminescence component at least, the aperture area size of this light hole 15 is according to required rising angle and go out optical range and decide, and wherein the aperture area of light hole 15 is at least less than 1/10th of this snoot 1 whole spheroid area.

Be noted that snoot 1 in the present embodiment can also be that an ellipsoid or other have the ball-type body of curved surface, the light source reflecting surface of this snoot 1 also can be a ball-type body that is formed by plane, a plurality of unit 111 ring structures, sees also shown in Figure 6.

Consult Fig. 4, be the light emitting path schematic diagram of lighting device improvement described in the utility model.When luminescence unit 3 penetrates an incident ray, wherein the first part light D1 directly is projected in the environment space via light hole 15, and second partly light D2 can directly reflect or via repeatedly reflecting via light source reflecting surface 11, project environment space by this light hole 15 at last, see through the aperture area and the shape of default this light hole 15, and diffusion and the principle of reflection of application light in the ball-type body, make output beam can be controlled in certain rising angle and effectively reduction light loss, so make whole light extraction efficiency effectively promote.

Consult Fig. 5, be an embodiment schematic diagram of the luminescence unit of lighting device described in the utility model improvement.Luminescence unit 3 described in the utility model also can utilize a plurality of different photochromic LED luminescence components that produce, use and reach a kind of output beam with mixed light effect, as shown in Figure 5, this luminescence unit 3 is to use 3
