Main element symbol description
The following specific embodiment further illustrates the present invention in connection with above-mentioned accompanying drawing.
The specific embodiment
Please refer to shown in Fig. 1, first embodiment of the invention provides is applied to the lamp system 100 to Vehicle Driving Cycle road lighting, comprises a LASER Light Source 10, some speculums 20, a light conversion element 30 and a reflecting plate 40.It should be noted that, Figure of description is only that the structure that schematically shows lamp system 100 of the present invention forms, and in fact the LASER Light Source in the present invention 10, speculum 20, light conversion element 30 and reflecting plate 40 are not distributed in same plane each other.
Described LASER Light Source 10 comprises some laser diodes 12, and described laser diode 12 is electrically connected to the storage battery in car, utilizes storage battery in car to provide electric power for it.When in the present embodiment, described laser diode 12 is worked, send blue light.
Described speculum 20 is positioned on the light direction of described LASER Light Source 10, for the light that LASER Light Source 10 is produced, reflexes to light conversion element 30.The number of speculum 20 is identical with the number of laser diode 12, and each speculum 20 is corresponding with a laser diode 12.Each speculum 20 be shaped as tabular.Each speculum 20 has a smooth reflecting surface 21.The light that each laser diode 12 sends projects the reflecting surface 21 of a speculum 20 accordingly, and the reflecting surface 21 of each speculum 20 arrives light conversion element 30 by light reflection.
Referring to Fig. 2 and Fig. 3, described light conversion element 30 comprises substrate layer 32, a reflecting layer 34, fluorescent material 36 and the scattering particles 38 of a printing opacity.Compare with this substrate layer 32, this reflecting layer 34 arranges further from this speculum 20.In the present embodiment, described fluorescent material 36 and scattering particles 38 all mix this substrate layer 32 inside.The material of this substrate layer 32 can be optical resin or silica gel.The material of scattering particles 38 can be the organic resin with high light transmittance.The shape of scattering particles 38 can be proper sphere body, regular or irregular orbicule, tetragonal body.
The light that laser diode 12 sends, after speculum 20 reflexes to light conversion element 30, first enters the substrate layer 32 of light conversion element 30, then by the reflecting layer 34 of light conversion element 30, is reflexed to reflecting plate 40.Light, in the process into and out of substrate layer 32, is had an effect with fluorescent material 36 and scattering particles 38 in substrate layer 32.38 pairs of light of scattering particles play scattering process, by light be converted into that area is large, the uniformity better, the face type light source of chroma stability.Fluorescent material 36 changes the color of light.In the present embodiment, the light that fluorescent material 36 sends laser diode 12 is converted into white light.
Described reflecting plate 40 is positioned on the light direction of described light conversion element 30, and it is shaped as arc, reflexes to car outer for illumination for the light that light conversion element 30 is produced.Described reflecting plate 40 has the reflecting surface 41 of an indent, and the light direction of described light conversion element 30 is towards the reflecting surface 41 of described reflecting plate 40.
The light source of lamp system of the present invention adopts laser diode 12, the light that laser diode 12 sends transforms through speculum 20, light conversion element 30 and reflecting plate 40 successively, the spot light effectively laser diode 12 being produced is converted into that area is larger, the uniformity better, the face type light source of chroma stability, greatly improved the light utilization ratio of laser diode 12.
Figure 4 shows that the light conversion element 30a of the lamp system in second embodiment of the invention.This light conversion element 30a comprises substrate layer 32a, a reflecting layer 34a, fluorescent material 36a and the scattering particles 38a of a printing opacity.It is inner that described fluorescent material 36a mixes this substrate layer 32a.The material of this substrate layer 32a can be optical resin or silica gel.The material of scattering particles 38a can be the organic resin with high light transmittance.The shape of scattering particles 38a can be proper sphere body, regular or irregular orbicule, tetragonal body.The difference of the second embodiment and the first embodiment is: the modes such as described coating for scattering particles 38a, spraying are formed on the outer surface of this substrate layer 32a away from reflecting layer 34a.
