(Projector part)
The projector unit 120 will be described with reference to FIGS. As shown in the block diagram of FIG. 3 and the configuration diagram of the projector unit in FIG. 4, the projector unit 120 includes a projection optical system 121, a reflective liquid crystal panel 122, an LED light source 123, a condensing optical system 124, a mirror 125, a PBS. (Polarization beam splitter) block 126, projection control circuit 127, and polarizer 128 are included. The reflection type liquid crystal panel 122 as the projection image forming unit generates a projection image in the image display area 122 </ b> A of the reflection type liquid crystal panel 122 in accordance with a drive signal from the projection control circuit 127. That is, the image display area 122A is an effective area used for forming a projected image. A projection image is not formed in the invalid area 122B. The projection control circuit 127 sends a control signal to the LED light source 123 and the reflective liquid crystal panel 122 in accordance with a projection command output from the CPU 101A.

  The LED light source 123 is a white LED made of, for example, a blue LED and a yellow phosphor, and emits white light based on a projection command of the CPU 101A input via the projection control circuit 127. The condensing optical system 124 is a collimating optical system that converts white light emitted from the LED light source 123 into parallel light and emits the parallel light toward the PBS block 126. The PBS block 126 is a polarization beam splitter having a polarization separation unit 126a that forms an angle of 45 degrees with respect to the optical axis of the illumination light emitted from the condensing optical system 124. A reflective liquid crystal panel 122 composed of a reflective liquid crystal element (LCOS) is disposed on the upper surface of the PBS block 126.

  A mirror 125 is disposed on the surface of the PBS block 126 on the condensing optical system 124 side. As shown in the schematic layout diagram (perspective view) of the projector unit in FIG. 5A, the mirror 125 has an opening 125OP corresponding to the shape of the image display region 122A of the reflective liquid crystal panel 122. For example, the opening 125OP has a rectangular shape. The mirror 125 is formed by evaporating aluminum or the like on the PBS block 126, for example, and reflects the light that reaches the invalid area 122B of the reflective liquid crystal panel 122 out of the illumination light emitted from the LED light source 123, so that the LED light source This is a reflection member for making the light incident on 123 again. As shown in FIG. 5B, the mirror 125 is provided so as to be orthogonal to the traveling direction of the parallel light emitted from the condensing optical system 124. Therefore, the light reflected by the mirror 125 returns to the LED light source 123 through almost the same optical path as the incident light to the mirror 125. A film-like polarizer 128 is provided in the opening 125OP of the mirror 125. That is, the mirror 125 is disposed so as to surround the periphery of the polarizer 128. The polarizer 128 may be disposed away from the mirror 125 along the light traveling direction.

  The reflective liquid crystal panel 122 is illuminated by illumination light emitted from the LED light source 123 and passing through the opening 125OP of the mirror 125, that is, transmitted through the polarizer 128. The surface 126b of the PBS block 126 is subjected to non-reflective processing such as black processing, for example.

  FIG. 6 is an enlarged sectional view showing the LED light source 123. The LED light source 123 includes a base member 1230, a light emitting diode element (hereinafter referred to as an LED chip) 1231, a cover 1232, an electrode 1233, a wire 1234, and the like. The LED chip 1231 provided on the base member 1230 is a white LED in which a blue light emitting body (LED) is covered with a yellow light emitting phosphor. That is, the blue light emitted from the blue light emitter passes through the yellow light emitting phosphor and is emitted as blue component light, and excites the yellow light emitting phosphor. The excited phosphor emits yellow component light. As a result, white light is emitted from the LED chip 1231.

  The cover 1232 is formed in a hollow dome shape with a hemispherical surface by a transparent member such as plastic, and is provided on the base member 1230 so as to cover the LED chip 1231. A space S formed between the cover 1232 and the base member 1230 is filled with a transparent gel-like substance having substantially the same refractive index as that of the cover 1232.

  Of the light that is reflected by the above-described mirror 125 and returned to the LED light source 123 and reaches the LED chip 1231, the reflected light of the blue component excites the yellow light-emitting phosphor constituting the LED chip 1231. As described above, the blue component light emitted from the blue light emitter of the LED chip 1231 also excites the yellow light-emitting phosphor, and in addition to this, the blue component reflected light is incident, so the amount of light emitted from the yellow light-emitting phosphor increases. To do. In addition, the reflected light of the blue component of the reflected light of the reflecting portion 1232b that is not used for the excitation is incident on the inside of the LED chip 1231, and is repeatedly reflected and refracted therein to repeat the LED chip. It injects towards the outside of 1231. Of the light that has been reflected by the reflecting portion 1232b and has reached the LED chip 1231, the light of the yellow component is repeatedly reflected and refracted inside the LED chip 1231, and is emitted toward the outside of the LED chip 1231 again.

  As described above, part of the light emitted from the LED chip 1231 again passes through the opening 125OP, and the other light is reflected by the mirror 125 and returns to the LED chip 1231 again. Then, the light returning to the LED chip 1231 is emitted from the LED chip 1231 again as described above. Therefore, the light emitted in the direction of the invalid area 122B of the reflective liquid crystal panel 122 can be used as the light toward the image display area 122A.

The operation of the projector unit configured as described above will be described with reference to FIGS.
A drive current based on a control signal from the projection control circuit 127 is supplied to the LED chip 1231 via the wire 1234 and the electrode 1233. The LED chip 1231 emits light having brightness according to the drive current toward the condensing optical system 124. The condensing optical system 124 makes the LED light substantially parallel and enters the polarizer 128. The polarizer 128 converts (or extracts) the incident light into linearly polarized light, and emits the converted (or extracted) polarized light toward the PBS block 126.

  A polarized light beam (for example, P-polarized light) incident on the PBS block 126 passes through the PBS block 126 and illuminates the reflective liquid crystal panel 122. The reflective liquid crystal panel 122 serving as a projection image forming unit includes a plurality of pixels on which red, green, and blue filters are formed, and generates a color image. When the light transmitted through the liquid crystal layer of the reflective liquid crystal panel 122 enters the reflective liquid crystal panel 122, the light travels upward in FIG. 4 and is reflected by the reflective surface of the reflective liquid crystal panel 122. The layer travels downward in FIG. 4 and exits from the reflective liquid crystal panel 122 and enters the PBS block 126 again. Since the liquid crystal layer to which the voltage is applied functions as a phase plate, the light incident on the PBS block 126 again becomes a mixed light of modulated light that is S-polarized light and unmodulated light that is P-polarized light. The PBS block 126 reflects (folds) only the modulated light, which is the S-polarized component, of the re-incident light beam by the polarization separation unit 126a, and emits the light toward the left projection optical system 121 as projection light.

According to the first embodiment described above, the following operational effects can be obtained.
(1) A mirror 125 having an opening 125OP having a shape corresponding to the image display region 122A is provided between the LED light source 123 and the reflective liquid crystal panel 122. Then, out of the light emitted from the LED light source 123, the light that does not enter the image display area 122A is reflected by the mirror 125 and returned to the LED light source 123, and is emitted again as light directed to the image display area 122A. Therefore, the occurrence of unevenness in illumination light caused by the geometric optical differences between the optical path lengths of the LED light source 123 and the reflective liquid crystal panel 122 and the optical path lengths of the mirror 125 and the reflective liquid crystal panel 122 is suppressed. Therefore, the image quality of the projected image can be improved. Furthermore, since the light incident on the invalid area 122B that has not been used in the past can be used, the light utilization efficiency of the LED light source 123 can be improved, and the amount of light incident on the image display area 122A can be improved to improve the projection image. Brightness can be increased.

(2) Since the mirror 125 reflects the light incident on the invalid region 122B and returns it to the LED light source 123, the reflected light does not enter the PBS block 126, and the generation of scattered light that causes ghosting is prevented. Can do.

(3) The LED chip 1231 is a white LED that emits white light by blue component light emitted from the LED and yellow component light that is emitted when the phosphor is excited by the blue component light. The yellow phosphor can also be excited by the blue component of the reflected light from the mirror 125 using the LED chip 1231 having the above characteristics. That is, the light of the LED chip 1231 that was not originally used as projection light (illumination light) can be reused for excitation of the phosphor, and the amount of light emitted from the LED light source 123 can be increased.

The projector unit 120 of the first embodiment described above can be modified as follows.
(1) Instead of the mirror 125 being provided so as to contact the PBS block 126 as shown in FIG. 4, the mirror 125 may be provided separately from the PBS block 126. Further, as the mirror 125, aluminum or the like may be deposited on the lower surface of the PBS block 126.

(2) When accuracy cannot be obtained at the peripheral portion of the condensing optical system 124, that is, when the light emitted from the peripheral portion of the condensing optical system 124 does not become parallel light, the mirror 125 is shown in FIG. It may be provided as shown. In this case, the mirror 125 may have a predetermined curvature (optical power) so that the reflected light from the mirror 125 returns to the LED light source 123 through the same optical path as the incident light to the mirror 125. As shown in FIG. 7B, aluminum or the like may be vapor-deposited on the exit side to the PBS block 126 on the surface of the condensing optical system 124 to form a reflecting member.

(3) When the condensing optical system 124 includes a plurality of lenses 124a and 124b, a mirror 125 may be provided between the lenses 124a and 124b. An arrangement example in this case is shown in FIG. FIG. 8A shows a case where the mirror 125 is arranged so as to be orthogonal to the traveling direction of the parallel light emitted from the lens 124a. FIG. 8B shows a case where the mirror 125 has a predetermined optical power when the light emitted from the periphery of the lens 124a does not become parallel light, as in the case of (2) above. . Note that Al or the like may be vapor-deposited on the lens 124a to form a reflecting member.

(4) The mirror 125 may be formed so that at least a part thereof corresponds to the image display region 122A. In other words, it may have a shape that reflects only light incident on the ineffective area 122B in the vertical or horizontal direction of the reflective liquid crystal panel 122. For example, as shown in FIG. 9, it is assumed that the image display area 122A is a substantially rectangular shape including a side L1 and a side L2 (L1> L2). Further, in the invalid area 122B, an area in contact with the side L1 in the longitudinal direction of the image display area 122A is defined as an invalid area 122Ba, and an area in contact with the side L2 in the short direction of the image display area 122A is defined as an invalid area 122Bb. At this time, since the area of the invalid region 122Ba is larger than the area of the invalid region 122Ba, the mirror 125 is disposed so as to reflect the light incident on the invalid region 122Ba in contact with the side L1 in the longitudinal direction of the image display region 122A. That's fine.

-Second Embodiment-
With reference to FIGS. 10 and 11, a second embodiment of an electronic camera with a projector provided with a projector according to the present invention will be described. In the following description, the same components as those in the first embodiment are denoted by the same reference numerals, and different points will be mainly described. Points that are not particularly described are the same as those in the first embodiment. This embodiment is different from the first embodiment in that a reflective member is provided in the LED light source 123 instead of the mirror 125.

  As shown in FIG. 10, the polarizer 128 is arranged on the PBS block 126 side with respect to the condensing optical system 124. In other words, in the projector 120 according to the second embodiment, the reflecting portion 1232b (FIG. 11) corresponding to the mirror 125 according to the first embodiment is arranged closer to the LED light source 123 than the polarizer 128.

  As shown in the cross-sectional view of the LED light source 123 in FIG. 11A, a reflection film is provided on the outer peripheral surface of the cover 1232 of the LED light source 123 in the second embodiment except for a predetermined region near the top. ing. That is, the cover 1232 is formed with a transmission part 1232a that transmits light emitted from the LED chip 1231 and a reflection part 1232b that reflects the emitted light. The transmission part 1232 a is provided on the top of the cover 1232, transmits white light emitted from the LED chip 1231, and guides it to the condensing optical system 124. As shown in the external view of FIG. 11B, the area of the transmissive portion 1232a is determined based on the shape of the image display area 122A of the reflective liquid crystal panel 122. That is, the area of the transmission part 1232a is set so that all the light transmitted through the cover 1232 enters the image display area 122A.

  The reflection part 1232b is provided to return light that is not used as illumination light to the light source and reuses the light emitted from the LED chip 1231 as it is, such as aluminum. Is deposited on the surface of the cover 1232. Since the reflecting portion 1232b is provided on the outer peripheral surface of the hemispherical cover 1232, the light emitted from the LED chip 1231 and reflected by the reflecting portion 1232b is incident on the LED chip 1231 located substantially at the center of the hemisphere. As described above, since the area of the transmissive part 1232a is determined based on the image display area 122A of the reflective liquid crystal panel 122, all the light not incident on the image display area 122A is reflected by the reflective part 1232b and the LED chip 1231. Returned to

  The light that has been reflected by the reflecting portion 1232b and reached the LED chip 1231 is incident on the inside of the LED chip 1231 in the same manner as in the first embodiment, and is repeatedly reflected and refracted inside to repeat the LED chip 1231. Inject toward the outside. A part of the light emitted from the LED chip 1231 again passes through the transmission part 1232a, and the other light is reflected by the reflection part 1232b and returns to the LED chip 1231 again. Therefore, the light emitted in the direction of the invalid area 122B of the reflective liquid crystal panel 122 can be used as the light toward the image display area 122A.

According to the second embodiment described above, the following operational effects can be obtained.
(1) A transmissive portion 1232a having a shape corresponding to the image display region 122A and a reflective portion 1232b for reflecting the emitted light are provided on the outer peripheral surface of the cover 1232 of the LED light source 123. The reflection unit 1232b returns light that is not incident on the image display area 122A out of the light emitted from the LED chip 1231 to the LED chip 1231 and emits the light toward the image display area 122A. As a result, since light incident on the invalid region 122B that has not been used in the past can be used, the same effect as the effect (1) obtained in the first embodiment can be obtained.

(2) As shown in FIG. 11, the shape of the reflecting portion 1232b is formed so as to correspond to the image display region 122A, and does not enter the condensing optical system 124 out of the light emitted from the LED chip 1231. The light was also returned to the LED chip 1231 and reused. Therefore, as in the conventional LED light source 223 shown in FIG. 12, the light LA that is not effectively used can be used, which is emitted in the side surface direction of the LED chip 223a. Therefore, compared with the LED light source 123 in the first embodiment, The light utilization efficiency of the emitted light can be improved.

(3) The reflection part 1232b is provided on the cover 1232, that is, the reflection part 1232b is provided on the LED chip 1231 side with respect to the polarizer 128. Therefore, it is possible to reliably guide the light that has been reflected by the reflecting portion 1232 b and then emitted through the transmitting portion 1232 a to the polarizer 128.

The projector unit 120 of the second embodiment can be modified as follows.
(1) Instead of providing the transmission part 1232a and the reflection part 1232b on the cover 1232 of the LED light source 123, a cap having a transmission part and a reflection part may be provided. FIG. 13 shows a cross section of the LED light source 123 in this case. The LED light source 123 is formed of a transparent member having substantially the same refractive index as that of the cover 1232 and is formed in a semispherical hollow dome shape, and has a cap 1235 provided so as to cover the cover 1232. Note that the cap 1235 and the cover 1232 may be in close contact as shown in FIG. 13, or a space may exist between the cap 1235 and the cover 1232. When there is a space, it is filled with a transparent gel-like substance having substantially the same refractive index as that of the cap 1235 and the cover 1232.

  The cap 1235 includes a transmission part 1235a and a reflection part 1235b in which aluminum deposition or the like is performed on the outer peripheral surface of the cap 1235. The area of the transmissive portion 1235a is determined based on the image display area 122A of the reflective liquid crystal panel 122. As a result, the cover 1232 and the transmission part 1235a transmit the white light emitted from the LED chip 1231 and guide it to the image display region 122A via the condensing optical system 124. Further, the white light transmitted through the cover 1232 and reflected by the reflecting portion 1235b passes through the cover 1232 again and returns to the LED chip 1231. Therefore, light that does not enter the image display region 122A out of the light emitted from the LED chip 1231 can be returned to the LED chip 1231 and reused.

(2) Instead of providing the reflecting portion 1232b on the outer peripheral portion of the cover 1232 by aluminum vapor deposition or the like, the reflecting portion 1232b may be provided on the inner peripheral portion of the cover 1232. Further, instead of providing the reflective portion 1235b on the outer peripheral portion of the cap 1235 in the above (1) by aluminum vapor deposition or the like, a reflective portion 1235b may be provided on the inner peripheral portion of the cap 1235.

The projector unit 120 in the first embodiment and the second embodiment described above can be modified as follows.
(1) The LED light source 123 may be one that emits white light using three LED chips that respectively emit R, G, and B colors. In this case, the light reflected by the reflecting portion and returned to the three LED chips is repeatedly reflected in the LED light source 123 and emitted to the outside. As a result, it is possible to contribute to an increase in the amount of light emitted from the LED light source by effectively using light that could not be effectively used as illumination light for the projected image.

(2) Instead of the PBS block 126, a wire grid polarizer or a birefringent reflective polarizer 400 shown in FIG.
(3) Instead of the reflective liquid crystal panel 122, a transmissive liquid crystal panel 500 shown in FIG. 14B can be used. Also in this case, the opening 125OP of the mirror 125 or the transmissive portion 1232a of the LED light source 123 is formed to have a shape corresponding to the image display region 500A of the transmissive liquid crystal panel 500.

(4) The present invention can also be applied to portable electronic devices such as a mobile phone and a PDA equipped with the projector unit 120.
(5) The solid state light emitting device is not limited to the light emitting diode described in the embodiment. A lamp may be used as the light source.

  In addition, the present invention is not limited to the above-described embodiment as long as the characteristics of the present invention are not impaired, and other forms conceivable within the scope of the technical idea of the present invention are also within the scope of the present invention. included.
