The above and other objects, features, and advantages of the present invention will become more apparent <RTIgt; Embodiments FIG. 2 is a schematic diagram of a light source system according to an embodiment of the present invention. Referring to FIG. 2, the light source system 3 of the present embodiment includes a light source 310, a light guiding mode group 320, and a light blocking element 33A. The light source 310 is adapted to emit a light, and the light guiding module 320 is disposed on one side of the light source 310, and the light guiding module 320 is adapted to collect and transmit the light emitted by the light source 31〇. The light blocking component 330 is disposed in the light guiding module 320, and the light blocking component 330 is adapted to block light in the light guiding module 320. In detail, the light source 31 of the embodiment is, for example, a mercury lamp, a light emitting diode, a metal halide lamp, a halogen lamp, a high intensity discharge lamp or other types of light sources, and the above light guiding mode The group 32 includes a concentrator 322 and a light guide 324. The concentrator 322 is disposed on one side of the light source 310, and the concentrator 322 is adapted to collect the light emitted by the light source 310. The light guiding column 324 is disposed on one side of the concentrator 322, and the light guiding column 324 is adapted to receive the light collected by the concentrator 322. Further, a light blocking member 33 is embedded between the light guiding column 324 and the light collector 322, and is adapted to block light transmitted from the light collector 322 to the light guiding column 324. Please continue with McCaw 2, which is generally composed of a wick 312 and a reflector 314. The wick 312 is disposed in the reflector 314, and the reflector 314 reflects the light emitted by the CCD 312. 8 1283328 17778twf.doc/g It is worth noting that since the reflector 314 does not reflect 100% of the light emitted by the wick 312, some of the light will still pass through the reflector 314. In other words, when the light source 31 of the light source system 3 is turned on, the light provided by the light source 310 is substantially transmitted in a specific direction, and the light that is emitted from the reflective cover 314 of the source 310 is collected by the light collector 322. Collected to enable these lights to be further utilized. As can be seen from Fig. 2, the φ light blocking element 330 embedded between the light guiding column 324 and the concentrator 322 can control the state of the light guiding column 324. The operation of the light blocking element 330 will be described below. For example, the operation of the light blocking element 330 can be controlled by a suitable software, firmware or hardware to determine whether the light blocking element 33 is to block light transmitted from the concentrator 322 to the column 324, or疋 Controls the extent to which light is blocked (eg, the blocked cross-sectional area) to control the state of the light guide 324 (eg, bright state of different brightness, sorrow or flicker, etc.). When the light blocking element 33〇 When the light transmitted from the concentrator 322 to the light guiding column 324 is blocked, the light guiding column 324 is in a dark state; conversely, when the light blocking element 33 〇 does not block the light transmitted from the concentrator 322 to the light guiding column 324 The light guiding column 324 will be in a bright state. On the other hand, when the light blocking member 330 blocks only part of the light transmitted from the concentrator 322 to the light guiding column 324, the light guiding column 324 will exhibit a low brightness state. It is worth noting that the light blocking component 330 can be a liquid crystal Valves, shutters, polarizers, etc. can weaken or completely block the light. For example, liquid crystal light valve, we can control the liquid crystal in the liquid crystal light valve by the driving circuit to receive the V light 324. The amount of light that is received to control the 9 1283323⁄4 twf.doc/g of the light guide column 324 (such as different degrees of light state, dark state, blinking state, etc.). On the other hand, if the shutter or polarizer is used as the photoresist When the component 33() is broken, the position of the shutter or the polarized light can be controlled by the transmission mechanism to control the state of the light guiding column 324 (such as different degrees of light state, dark state, flashing energy, etc.). When the shutter completely shields the light transmitted from the concentrator 322 to the light guiding column 324, the light guiding column 324 will appear in a dark state; when the shutter does not shield the light transmitted from the light collecting 322 to the light guiding column 324, the light guiding column 324 will assume the most awkward state; and when the shutter only shields part of the light transmitted from the concentrator 322 to the light guiding column 324, the light guiding column 324 will exhibit other brighter states of lower brightness. When the polarizer is completely shielded Passing from the concentrator 322 to the light guide 3 When the light of 24, or only a part of the light is blocked, the light guide column 324 will exhibit many different degrees of light state; and when the shutter does not shield the light transmitted from the light collector 322 to the light guide column 324, the light guide column 324 Figure 3 is a schematic diagram of a light source system according to another embodiment of the present invention. Referring to Figure 3, the light source system 3 of the present embodiment includes a light source and a light guiding module 320. The light source 310 is adapted to emit a light, and the light guide module 32 is disposed on one side of the light source 31, and the light guide module 320' It is suitable for collecting and transmitting the light emitted by the light source 31〇. The light blocking component 330 is disposed in the light guiding module 32, and the light blocking component 330 is adapted to block the light in the light guiding module 32. Further, the control unit 340 is coupled to the light blocking member 330 to control the operation of the light blocking member Ι 283 。. As shown in FIG. 3, the light guiding module 320 of the present embodiment is similar to the light guiding module 320 illustrated in FIG. 2, but the main difference between the two is that the light guiding module 320' of the embodiment is The light concentrating member 322 has a light converting substance 322a on the inside and/or the surface thereof. Specifically, the light converting substance 322a is adapted to absorb light transmitted to the concentrator 322 and emit secondary light. In a preferred embodiment of the invention, the light converting substance may be one or more kinds of fluorescent materials.

In view of the above, the present embodiment can obtain the required secondary light by selecting different light converting substances 322a, that is, the color exhibited by the light guiding column 324 (ie, the color of the secondary light) does not necessarily be emitted from the wick 312. The color of the light is the same. In this way, the manufacturer can select different light converting substances 322a (e.g., fluorescent materials) for the product requirements, so that the light guiding column 324 can exhibit the desired color. Referring to FIG. 2 and FIG. 3 , although FIG. 2 and FIG. 3 only depict one light blocking element 330 and one light guiding module 32 〇 or 32 〇, the present invention does not limit the light blocking element and the guide. The number of optical modules does not limit the type and number of light guides and concentrators in each light guide module. That is to say, in the present invention, two or more light guiding mode light guiding modules can be arranged at the periphery of the light source at the same time. In addition, it is noted that the light source system 300 of the light source system 300 shown in FIG. 3 has the control element 340 and the light conversion substance 322a at the same time, but the invention is not limited thereto. 11 I28331doc/g The light source system 300 needs to have both the control element 340 and the light converting substance 322a. That is, the light source system 300 may have the control unit 340 or the light conversion substance 322a alone. 4 is a schematic view of a projection apparatus using the light source system of FIG. 2 or 3.

Among them, the light source system 300 has been described above in detail, and therefore will not be described again. The optical engine 4 is adapted to receive the light provided by the light source system 300 and process the light into an image for projection onto the screen. In the present embodiment, the optical engine 4 is, for example, a digital image projection system, a liquid crystal projection device, a single crystal germanium liquid crystal display, or other micro-display system. Referring to FIG. 4, in the projection device 500, when the light source 310 of the light source system 3 or 300 is turned on, the light provided by the light source 310 is substantially transmitted to the optical engine 400 in a specific direction, but there is still a portion. The portion of the light passes through the reflector 314 in the light source 310. At this time, the concentrator 322 disposed on one side of the light source 31 收集 collects the light that is emitted from the reflector 314 of the light source 310 so that the light can be further utilized. It is to be noted that when the light source system 300 or 300 is applied to the projection device 500, visible light and non-visible light (e.g., ultraviolet light) that are emitted from the reflective cover 314 can be efficiently collected and reused (re_use).
