New description: [New technical field] This creation is about a light source module and projection device, and particularly relates to a light source module and projection device that can switch different light sources. [Prior Art] With the advancement of environmental awareness and the advancement of display technology, in addition to the use of ultra high pressure lamp (UHP lamp) as a light source, the projection device has recently developed red, green and blue light. A light emitting diode (LED) is used as a projection device for a light source. In order to effectively increase the output brightness of the projection device, some conventional artisans may configure a dual light combination module, a dual lamp module or a LED array in the projection device. The optical module is used to increase the brightness of the light source by increasing the number of light sources. However, since the optical module described above is not disposed on the optical axis of the projection device, the displacement of the spot and the angle of the received light are caused, so that the overall brightness of the projection device is not as high as desired. On the other hand, other conventional artisans generate a high-brightness light source by irradiating an excitation beam with a phosphor, and use such a light source as an illumination source of a projection device, for example, U.S. Patent Publication No. 20090284148 and 20090262308. However, the light source generated by the above method often has a problem of white spots being impure, thereby affecting the image quality of the projection apparatus. θ M423266 [New content] This creation provides a % source module that provides high brightness and rfj color purity. ’' This creation provides a projection device that provides a projection effect of high-pitched sound and purity. Other purposes and advantages of this creation can be learned from this creative feature cap to the next step.

Referring to FIG. 1, the projection apparatus 100 of the present embodiment includes a light source module 110, a light valve 120, and a projection lens 130. The light source module 11A includes a light emitting element 112a, a light emitting element 112b, a wavelength converting element 114, a light emitting element 112c, and a light combining element 116. In the present embodiment, the light-emitting element 112a is, for example, a blue solid-state laser or an ultraviolet laser (Ultravi〇let laser). In other embodiments, the light-emitting element 112a may also be a blue light emitting diode. Further, the light-emitting elements 112b, 112c, M423266 are, for example, light-emitting diodes. However, the above elements are used for exemplification, and the present invention is not limited to the above elements. As shown in FIG. 1, the light-emitting element 112a is adapted to emit an excitation beam Eex (excitation beam), wherein the excitation beam is a laser beam. In addition, the full width half-Maximmn (FWHM) of the excitation light beam Lex of the light-emitting element 112a is, for example, 25 nm, and the wavelength range corresponding to the above-mentioned light intensity half-free is, for example, from 450 nm to 475 nm, but this creation is not limited to this.

In addition, it can be seen from the comparison of the wavelength range of the color light beam L1 and the color light beam L2 that, in the present embodiment, the light intensity of the light beam L2 corresponds to the half-width of the light beam and the color light beam L1. The wavelength ranges corresponding to the intensity half width and width are at least partially overlapped. It is worth mentioning that although the color light beam L2 and the color light beam L1 of the present embodiment are both green light, the brightness of the color light beam L2 is higher than that of the color light beam L1, and the color purity of the color light beam u is smaller than the color of the color light beam L2.

The light valve 120 is disposed between the light source module 11A and the projection lens 13A, wherein the light valve 120 is adapted to convert the illumination beam into an image beam and transmit it to the projection lens 130. In this embodiment, the light valve 120 is, for example, a digital micro-mirror device (DMD), a liquid-crystal-on-silicon panel (LCOS panel), or a liquid crystal panel M423266 (liquid-crystal Panel, LC panel). Further, the projection lens 130 is disposed on the combined transmission paths PI, P3 of the color light beam L1 and the color light beam L3 or the combined transmission paths P2, P3 of the color light beam L2 and the color light beam L3. Referring to FIG. 1, the light source module 11 of the embodiment further includes a light emitting element 112d. The light emitting element 112d is adapted to emit a color light beam L4. As shown in Fig. 1, the light combining element 116 is disposed on the transmission path P4 of the color light beam L4. In the present embodiment, the colors of the color light beam L1, the color light beam L3 and the color light beam L4 are different from each other' and the color light beams L2, the color light beams L3 and the color light beams L4 have different colors from each other. In detail, the color light beams L1 and L2 are, for example, green light, and the color light beams L3 and L4 are, for example, red light and blue light, respectively. However, in other embodiments, the color beams L3 and L4 may also be blue and red, respectively. As shown in FIG. 1 , the light combining element 116 of the present embodiment is used for transmitting the color light beam L1 emitted by the light emitting element 112b, the color light beam L3 emitted by the light emitting element 112c, and the color light beam L4 emitted by the light emitting element 112d. The P3 and P4 are combined, or the color light beam L2 converted by the wavelength conversion region 114a, the color light beam L3 emitted from the light-emitting element 112c, and the transmission paths P2, P3, and P4 of the color light beam L4 emitted from the light-emitting element 112d are combined. In this way, the color light beam can generate a colored surface after passing through the light valve 120 and the projection lens 130. Additionally, the projection device 100 also includes a light homogenizing element 140. The light homogenizing element 140 is disposed between the light combining element 116 and the light valve 120. The light homogenizing element 140 element is, for example, a light integration rod. In addition, the projection apparatus 100 of the present embodiment may also include a lens 150.

Referring to FIG. 1 and FIG. 2A, the color light beams L3, L2, and L4 are sequentially supplied to the light combining elements 116 in FIG. 1 at different times, for example, so that the light combining elements U6 can guide the color light beams to In the same direction. Since the brightness of the color light beam L2 is higher than the color light beam L1, when the user wants to obtain a projection surface with a higher brightness, the light-emitting element 112a is turned on and matched with the rotation of the wavelength conversion element U4, so that the excitation light beam Lex is irradiated at the wavelength. The conversion area 114a is obtained to obtain a color light beam L2 having a higher luminance. Then, after the color light beams L3, L2, and L4 sequentially pass through the light combining elements 116, the transmission paths P3, P2, and P4 of the color light beams L3, L2, and L4 are combined (that is, the combined light beams LA on the transmission path PA) ), and sequentially transmitted to the light valve 12 〇 and the projection lens 13 〇. At this time, the user can also turn off another light-emitting element U2b that provides high-purity green light to save energy.

Then, after the color light beams L3, LI, and L4 sequentially pass through the light combining elements 116, the transmission paths P3, Π, and P4 of the color light beams L3, LI, and L4 are merged (that is, the combined light beams LB on the transmission path pB). ) and sequentially transmitted to the light valve 12 〇 and the projection lens 130. At this time, the user can turn off the light-emitting element U2a to avoid interference of the converted color light beam L2, and achieve an energy-saving effect. However, in the above embodiment, the color light beam Li having a higher color purity is passed through the penetrating region 114b, and in other embodiments, the user can also turn on the light emitting element 112a and match the rotation state of the wavelength conversion element 114. The partial excitation beam Lex is penetrated through the penetration region i 4b and sequentially transmitted to the light combining element 116, the light valve 120 and the projection lens 13A. In this way, the output brightness of the projection device 1 can be increased by the supply of the excitation light beam Lex. In other words, the opening or closing end of the light-emitting elements 112a and 112b is determined depending on the projection effect desired by the user, and the present creation is not limited to the above. . In addition, the area allocation of the wavelength conversion region 114a and the transmission region 114b of the wavelength conversion element 114 can also be adjusted according to user requirements. For example, if a projection effect of high brightness is desired, it can be achieved by increasing the area of the long conversion region IHa on the wavelength conversion element. The other f-plane' can be achieved by the area on the wavelength conversion element 114 by the booster port 2, the region 114b, if the projection wire of the high color purity is desired. From the above, it is known that the projection m of the present embodiment can achieve the switching effect of the beam and the high-purity beam by using only the area division of the wavelength conversion element ιΐ4 t ^ conversion region 114 & and the penetration region 114b. In other words, in the embodiment of the present 11 M423266, the user can provide two different light sources without requiring a complicated optical structure. Therefore, the light source module 110 and the projection device 1 of the present embodiment have good applications. Flexibility.

In this way, the color beams L1, L3, L4 (i.e., the light beam LB) or the color light beams L2, L3, L4 (i.e., the light beam LA) of different colors can be transmitted to the light valve 丨2〇, and the above-mentioned light beams LA, LB pass through After the action of the light valve 120, a color image plane can be formed. In addition, the light source module 11 of the embodiment further includes a color separation unit 118. The color separation unit ns is disposed on the transmission path Pex of the excitation light beam Lex between the light-emitting element 112& and the wavelength conversion element, and the transmission path of the color light beam L1 between the light-emitting cow 112b and the wavelength conversion element 114 is stupid.
