Accompanying drawing is combined to being described in further detail below by detailed description of the invention.
Embodiment one:
As it is shown in figure 1, in the present embodiment, the luminous body 10 of luminescent device is column structure, and luminous body 10 includes setting in opposite directions
The 101, second face 102, the first face put and the side face 103 connecting the 101, second face 102, the first face, the first face 101 and second
102 two ends being positioned at luminous body 10, side face 103 is the side of luminous body 10.
On luminous body 10 is axially extending to the second face 102 along the first face 101, its cross section is identical, and cross section can be round
Shape, ellipse, triangle, tetragon or other shape, when the first face 101 and the second face 102 use circle, luminous body 10
It is cylinder；When the first face 101 and the second face 102 use square or rectangular, luminous body 10 is cuboid.
The light inlet 1011 of luminescent device is positioned on the first face 101 of luminous body 10, whole of second face 102 of luminous body 10
As the part in light-emitting window or the second face 102 as light-emitting window, reflective areas is located at least in the side face of luminous body 10.
When the luminescent device of the present embodiment uses in light-source system, the collocation design of luminescent device and excitation source 40 was both
Can be that excitation source 40 as shown in Fig. 2 (a) is close to light inlet 1011 and is placed thus exciting light is launched directly into light mouth
1011, it is also possible to as shown in Fig. 2 (b), the exciting light sent is irradiated into after lens 50 collimate/converge by excitation source 40
Light mouth 1011.
Having Stimulated Light in luminous body 10 and produce material, such as fluorescent material or quantum dot etc., luminous body 10 can be fluorescence
The fluorescent glass that powder sinters in being dispersed in the materials such as glass, or it is dispersed in the fluorescence solidifying to form in organic adhesive
Body.Certainly, luminous body can also obtain by other means, as long as it is to produce material i.e. containing Stimulated Light in light transmission medium
Can.
As it is shown on figure 3, the blue light exciting light that excitation source 40 is launched is irradiated to fluorescent powder grain by after light inlet 1011
On 104, thus excitation fluorescent powder grain 104 produces Stimulated Light, Stimulated Light through other fluorescent powder grain scattering with
And after the reflection of echo area, eventually from light-emitting window outgoing；It addition, the exciting light excited the most completely, may proceed to irradiate
To other fluorescent grain and produce exciting light, final outgoing after scattering and reflection.In the present embodiment, light inlet 1011 is for setting
Put at the anti-reflection film of emitter surface or saturating blue film, or for the emitter surface not covered by reflective areas；Or work as reflective areas

Along the first face 101, to the second face 102, axially extending its cross section upper is gradually increased body of light, in one embodiment, and first
The area in face 101 can be zero.
The cross section of luminous body can be circle, ellipse, triangle, tetragon or other shape, when luminous body
When cross section uses circular, vertebral body structure is cone；When the cross section of luminous body uses triangle, square, rectangle
Or during its shape, vertebral body structure is corresponding cubic structure.
At least one light inlet 1011 of luminescent device may be located on the first face 101 of this vertebral body structure, it is also possible to as
Fig. 5 (a) show the region on vertebral body structure side face 103.Whole of second face 102 of vertebral body structure is as light-emitting window or second
The part in face 102 is as light-emitting window, in Fig. 5 (b), on the side face 103 of vertebral body structure region in addition to light inlet 1011 and
The composition reflective areas, region in the first face 101.
When the luminescent device of the present embodiment uses in light-source system, light-source system include at least one excitation source 40 with
And the radiator 30 being arranged on the wall of reflective areas, excitation source 40 arranges with light inlet 1011 one_to_one corresponding, both can be close to
Light inlet 1011 surface is placed thus exciting light is launched directly into light mouth 1011, it is also possible to passed through thoroughly by the exciting light sent
It is irradiated into light mouth 1011 after mirror collimation/convergence.
Having Stimulated Light in luminous body 10 and produce material, such as fluorescent material or quantum dot etc., luminous body 10 can be fluorescence
The fluorescent glass that powder sinters in being dispersed in the materials such as glass, or it is dispersed in the fluorescence solidifying to form in organic adhesive
Body.
The blue light illumination that excitation source 40 is launched on fluorescent powder grain thus produce Stimulated Light, Stimulated Light is glimmering through other
After the scattering of light powder particles and the reflection of echo area, eventually from light-emitting window 102 outgoing.In the present embodiment, light inlet
1011 are coated with blue film is conducive to blue light exciting light incident, and light-emitting window is coated with anti-reflection film and is conducive to Stimulated Light outgoing.Except light inlet
1011 and light-emitting window outside, other region of vertebral body structure polishes and plates reflectance coating, thus beneficially Stimulated Light is at luminous body 10
In fully reflect.
As shown in Fig. 6 (a), using first design identical with second area, a part of Stimulated Light 601 is being sent out
In the luminescent device of body of light 10 after multiple reflections, finally to deviate horizontal line larger angle outgoing, a part of Stimulated Light also can be by
It is limited in luminescent device, by echo area wall Circulated reflection；And as shown in Fig. 6 (b), use the cone structure of the present embodiment
Luminescent device, Stimulated Light 602 after multiple reflections, finally goes out with deviation horizontal line smaller angle in the luminescent device of vertebral body structure
Penetrate, and do not have the situation that Stimulated Light is limited in luminescent device, so that the light formed after all beam projectings
Shu Gengjia is uniform, more concentrates, the efficiency of the luminescent device improved further.
