Description
Technical field
But the present invention relates to a kind of lighting device of leaded light, relate in particular to a kind of utilization and be provided with a light hole, make light can be directed to suitable direction, but so that the lighting device of the leaded light that whole light extraction efficiency effectively promotes at ball-type body reflector.
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.
With reference to figure 1, schematic diagram for a light guide 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.
With reference to figure 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.
Summary of the invention
But main purpose of the present invention is to provide a kind of lighting device of leaded light, 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.
In order to achieve the above object, but the invention provides a kind of lighting device of leaded light,, include in order to produce a convection light:
One light-guiding shade, this light-guiding shade is a ball-type body, it has an incidence hole and a light hole, this incidence hole is in order to settle a luminescence unit, this luminescence unit is in order to provide an incident ray, the Internal Spherical Surface of this light-guiding shade is a light source reflecting surface, and this incident ray is projected to environment space by this light hole at last via in the primary event of this light source reflecting surface or repeatedly reflection.
This luminescence unit comprises a LED luminescence component at least.
When this luminescence unit includes a plurality of LED luminescence component, and the LED luminescence component comprises and at least onely can produce different photochromic LED luminescence components.
This light source reflecting surface is for to be formed by plane, a plurality of unit.
Be formed with a blooming on this light source reflecting surface.
The aperture area of light hole is at least less than 1/10th of the whole spheroid area of this light-guiding shade.
The present invention can solve the disappearance of above-mentioned prior art, light can be directed to suitable direction, therefore effectively improves brightness and effectively promotes the light source utilization rate.
