Abstract
The invention discloses a light source device and a projector adopting the same, which relate to the technical field of laser display and solve the problems that the existing light source device is complicated in structure, high in cost and higher in energy consumption. In the embodiment of the invention, as the light source device adopts a transmission type fluorescence plate, green rays generated by exciting green emitting phosphor by blue laser can transmit the transmission type fluorescence plate, and runs along the direction the same with the running direction of the blue laser transmitting the transmission type fluorescence plate, so that the running directions of blue rays and the green rays transmitting the transmission type fluorescence plate can be the same with that of red rays by only one dichroic mirror, thereby simplifying the structure of the light source device; and after transmitting the transmission type fluorescence plate, the blue rays can reach a emitting position by passing by the only one dichroic mirror, thereby greatly shortening an optical path and avoiding larger energy loss so as to reduce the energy consumption of the light source device.
Description
Technical field
The present invention relates to laser display technology field, the projector that relates in particular to light supply apparatus and apply it.
Background technology
Laser display technology is usingd red laser, green laser, blue laser and as light source, is reproduced the display technique of objective world rich colors, and wherein, the laser of every kind of color can be produced by semiconductor laser.
At present, the also prematurity of the technology of green light semiconductor, if adopt green light semiconductor can produce serious speckle as green-light source, affects the quality of display frame.Utilize blue-light semiconductor laser instrument to excite green emitting phosphor to produce the principle of green glow, solved above-mentioned speckle issue.
Fig. 1 is the schematic diagram of the light supply apparatus made of principle existing, that utilize blue-light semiconductor laser instrument to excite green emitting phosphor to produce green glow.
Light supply apparatus comprises: blue-light semiconductor laser instrument 11, red light semiconductor laser 12, fluorescent plate 13 and light-gathering optics.Fluorescent plate 13 comprises blue light transmission area and green fluorescence tagma, the blue light b being sent by blue-light semiconductor laser instrument 11 can see through from blue light transmission area fluorescent plate 13, green emitting phosphor in green fluorescence tagma covers on the reflection horizon of fluorescent plate 13 substrates, the blue light b being sent by blue-light semiconductor laser instrument 11 is irradiated to and on green emitting phosphor, inspires green glow g, this green glow g is through the reflection in reflection horizon, towards the direction operation contrary with blue light b traffic direction.
The light being sent by blue-light semiconductor laser instrument 11, red light semiconductor laser 12 and penetrating from outgoing position X as light source by fluorescent plate 13 transmissions, the light that reflects are synthetic a branch of after light-gathering optics.
Light-gathering optics comprises: the first dichroic mirror 14, the second dichroic mirror 15, the first catoptron 16 and the second catoptron 17.Wherein, the first dichroic mirror 14 is for seeing through the lens of blue light and ruddiness reflect green light, and the second dichroic mirror 15 is for seeing through the lens of blue light reflect green light and ruddiness.
The blue light b that blue-light semiconductor laser instrument 11 sends exposes on fluorescent plate 13 after the first dichroic mirror 14 sees through, and excites green emitting phosphor to produce green glow g.The reflection horizon (not shown in figure 1) reflection of green glow g on fluorescent plate 13, towards the direction operation contrary with blue light traffic direction, after the first dichroic mirror 14 reflections, then through the second dichroic mirror 15 reflections, then penetrates from outgoing position X.
Along with fluorescent plate 13 rotates to transmission area, the blue light b that blue-light semiconductor laser instrument 11 sends sees through, and after the first catoptron 16 and the second catoptron 17 reflections, then sees through through the second dichroic mirror 15, then from outgoing position X, penetrates.The ruddiness r being sent by red light semiconductor laser 12 sees through through the first dichroic mirror 14, then through the second dichroic mirror 15 reflections, then from outgoing position X, penetrates.Ruddiness r, green glow g, blue light b just can synthesize and a branch ofly as light source, from outgoing position X, penetrate like this.
In above-mentioned light supply apparatus, because the green glow g by blue-light excited generation is by the reflective layer reflects on fluorescent plate 13, make green glow g contrary with the traffic direction of blue light r through fluorescent plate 13 transmissions, the light-gathering optics therefore need to more optical module is gathered together the light of different directions synthetic a branch of, for example, in Fig. 2, ruddiness r and green glow g need converge to outgoing position X through two dichroic mirrors, and blue light b need be after fluorescent plate 13 sees through, through two baffle reflections, then through the second dichroic mirror, see through and arrive outgoing position X again.More optical module, not only bad for the simplification of light supply apparatus structure, has also increased the cost of light supply apparatus.
In addition, because blue light b needs through two catoptrons before arriving outgoing position, optical path length and complexity, cause the energy loss of blue light b larger, thereby cause the energy consumption of light supply apparatus higher.
