Referring again to Fig. 2A, Fig. 2 B and Fig. 3, the light of filtration module 130 passes through an area T and at least filter area F On the transmission path that the excitation beam B from light combination element 120 can be cut in turn.When the light of filtration module 130 is cut by area T When on the transmission path of the excitation beam B in the color separation portion 122 from light combination element 120, as shown in Figure 2 A, excitation beam B passes through The light of filtration module 130 is exported by area T from filtration module 130.On the other hand, at least one described in the filtration module 130 Filter area F (the first color filter area F1, the second color filter area F2 or third color filter area F3 as shown in Figure 3) incision comes from light combination When on the transmission path of the excitation beam B in the color separation portion 122 of element 120, commutating optical beam CB by filtration module 130 it is described extremely A few filter area F, and exported from filtration module 130.Furthermore, it is understood that an at least filter area F will pass through light combination element 120 Color separation portion 122 excitation beam B reflection.The reflecting part 124 of light combination element 120 is arranged in described in filtration module 130 extremely On the transmission path of the excitation beam B of few filter area F reflection, so that by the excitation beam B in color separation portion 122 sequentially via institute It states at least reflection of a filter area F and reflecting part 124 and is transferred to wavelength convert module 140.Wavelength convert module 140 will swash The beam B that shines is converted into commutating optical beam CB, be wavelength-converted the commutating optical beam CB of the reflection of module 140 again via color separation portion 122 and The reflection of reflecting part 124 and towards filtration module 130 transmit.Lead in excitation beam B and Fig. 2 B for passing through area T by light in Fig. 2A The commutating optical beam CB for crossing an at least filter area F forms the illuminating bundle IB of Fig. 1.

Third color filter area F3 (Yellow filter area) incision that Fig. 2 B shows Fig. 3 passes through the color separation portion 122 of light combination element 120 Excitation beam B transmission path on when optical path.When third color filter area F3 incision passes through the color separation portion of light combination element 120 When on the transmission path of 122 excitation beam B, it is transferred at least portion of the commutating optical beam CB (yellow light beam) of filtration module 130 Divide (or whole) can connect to export by third color filter area F3 from filtration module 130.On the other hand, when the first color of Fig. 3 When on the transmission path that filter area F1 (red filter area) incision passes through the excitation beam B in the color separation portion 122 of light combination element 120, The first color beam (red beam) being transferred in the commutating optical beam CB (yellow light beam) of filtration module 130 can be connected by first Color filter area F1 and export, and be transferred in the commutating optical beam CB (yellow light beam) of filtration module 130 from filtration module 130 the Dichroscope beam (green beam) can be by the first color filter area F1 filtering (reflection or absorption).When the second color filter area F2 of Fig. 3 is (green Color filter area) incision pass through the excitation beam B in the color separation portion 122 of light combination element 120 transmission path on when, be transferred to optical filtering mould The second color beam (green beam) in the commutating optical beam CB (yellow light beam) of block 130 can be connected through the second color filter area F2 It is exported from filtration module 130, and the first color beam being transferred in the commutating optical beam CB (yellow light beam) of filtration module 130 is (red Color beam) it can be by the second color filter area F2 filtering (reflection or absorption).

Since the excitation beam B of self-excitation light emitting source 110 can be in the case where being not delivered to wavelength convert module 140 via conjunction Optical element 120 is first transferred to filtration module 130, and is transferred to the excitation beam B of filtration module 130 via filtration module 130 Light is exported by area T from filtration module 130, therefore can not have to be formed (such as in support plate 144) in wavelength convert module 140 to allow The opening that excitation beam B passes through, without additional setting for light combination element 120 will to be passed back to by the excitation beam B of opening Multiple smooth transmitting elements.Accordingly, lighting system 100 can have many advantages, such as small in size and at low cost.In addition, wavelength convert module 140 by the commutating optical beam CB of the excitation beam B conversion yellowly of blue, and the commutating optical beam CB of yellow is again via filtration module Multiple color light beam (such as feux rouges, green light and yellow light) needed for 130 multiple filter area F filter out illumination.That is, in wave Optical wavelength conversion material for converting out yellow light need to be only set in long conversion module 140, on support plate 144, and need not corresponding filter Wavelength convert module 140 is divided into light by area T and multiple filter area F and passes through area and setting difference by the light of optical module 130 Multiple wavelength-converting regions of optical wavelength conversion material.Therefore, the rotation of the rotation of filtration module 130 and wavelength convert module 140 It can be asynchronous.For example, wavelength convert module 140 can not rotate.Alternatively, wavelength convert module 140 is rotatable, but can not It does not need to be designed as with the rotation with 140 synchronous rotary of wavelength convert module, filtration module 130 and wavelength convert module 140 yet Synchronous rotary significantly saves the time that electric signal is handled in projection arrangement 10.It is only supported in this way, projection arrangement 10 can be selected The light valve 200 synchronous with the rotation of filtration module 130, to reduce the cost of projection arrangement 10.Accordingly, using lighting system 100 Projection arrangement 10 can also have many advantages, such as it is small in size and at low cost.

According to different demands, lighting system 100 optionally includes other elements.For example, lighting system 100 It may also include multiple lens elements, lens element 151 as shown in Figure 1, lens element 152, lens element 153, lens element 154 and lens element 155, to achieve the effect that converging beam or by beam collimation.In addition, lighting system 100 may also include Even optical element 160.The transmitting of the excitation beam B and commutating optical beam CB that export from filtration module 130 is arranged in even optical element 160 On path, to promote the uniformity of light beam.For example, even optical element 160 is optical integration pillar or lens array, but not with this It is limited.
