Summary of the Invention
Problems to be Solved by the Invention
[0004] When taking a self-photo using a prior art projector, a circular ring light from the light emitter is reflected on the surface of the cornea of the person taking the photo (hereinafter referred to as the self-photographer). And an image of the self-photographer in this state can be transmitted.
Means for Solving the Problems
[0005] The projector of the present invention has a light emitter in the shape of a heart. By using such a projector, a heart-shaped light can be reflected on the cornea of the self-photographer.
Effects of the Invention
[0006] The present invention has the effect of being able to obtain an image of a self-photographer with a heart-shaped light reflected on the cornea.

[Figure 6] (a) is a cross-sectional view showing the use of a floodlight while being photographed by a camera, and (b) is a side view of a desk lamp equipped with a floodlight. [Modes for carrying out the invention]
[0008] The following describes embodiments of the present invention based on the drawings. As shown in Figures 1(a), (b) and 2, a heart-shaped, annular light-emitting element 3 is fixed to the surface of the substrate 2 of the light-emitting device 1. This light-emitting element 3 has a large number of light-emitting diodes 4 arranged in the direction of the extension of the ring, and is covered with a translucent opaque cover 5 of the color white or the like so that all the light-emitting diodes 4 are housed inside. On the inner circumference side of the light-emitting element 3, a reinforcing plate 8 is fixed to the front surface of the substrate 2. This reinforcing plate 8 also has a positioning function for the light-emitting element 3. The power supply line to the light-emitting element 3 and the switch that makes the light-emitting element 3 light up are not shown. Inside the light-emitting element 3, a recess 10 is formed on the front surface of the substrate 2 as a mounting area for a photographic means such as a mobile phone, which is located in the center of the light-emitting area, and a slit 11 is provided at the lower end of the recess 10. A through hole 12 is formed at the top of the recess 10, which is located in the center of the light-emitting area.
[0009] As shown in Figure 5, the light-emitting body 3 has a flattened shape in the left-right direction relative to the regular heart shape α. Here, the regular heart shape α refers to the shape defined in "Unicode U+2661 (JISX0213)". Furthermore, while the upper and lower dimensions H1 and H2 of the regular heart shape α and the light-emitting body 3 are formed to be equal, the left-right width W2 of the heart shape of the light-emitting body 3 is formed to be narrower than the width W1 of the regular heart shape α. Note that the ratio of the width W1 of the regular heart shape α to its upper and lower dimension H1 is 1:1.
[0010] In using the floodlight 1 configured as described above, a stand 21 is used as a support member along with the floodlight 1, as shown in Figures 1 to 3. The substrate 2 of the floodlight 1 is supported on the support 22 on the leg 22a of the stand 21 so that the light-emitting element 3 faces the person taking the selfie, and the claw 23 at the lower end of the support 22 is hooked onto the slit 11 of the substrate 2. In this state, a mobile phone (smartphone) 14 with a camera function is fitted into the recess 10 and supported as a means of taking a picture. When the person taking the selfie brings their face close to the mobile phone 14 to an appropriate distance with the light-emitting element 3 illuminated, a heart-shaped light-emitting element 3 is projected onto the surface of the person taking the selfie's eyes, as shown in Figure 4. In this state, the mobile phone 14 can take and transmit an image of the person taking the selfie's face.
[0011] This embodiment has the following effects. (1) It is possible to take a picture of a person taking a selfie with a heart reflected in their eyes. Therefore, it is possible to send the picture.
[0012] (2) Because the light-emitting body 3 is flattened in the shape of a heart, when the light-emitting body 3 is reflected on the surface of the pupil, the entire heart shape expands due to the action of the spherical curve of the surface of the pupil, resulting in a natural normal heart shape α or a shape close to a normal heart shape α.
[0013] (3) The reduction rate of the width W2 of the light emitter 3 with respect to the width W1 of the regular heart shape α is formed to be 20 to 95%, preferably 40 to 80%, more preferably 50 to 70%, and even more preferably 55 to 65%. For this reason, when the light of the light emitter 3 is reflected in the pupil, the reflected light becomes a shape that is the regular heart shape α or a shape close to the regular heart shape α.
[0014] (4) As shown in Fig. 6(a), without using the mobile phone 14, insert the lens barrel 16 of the camera 15 as the three-legged photographing means through the upper through hole 12, and hang the projector 1 on the lens barrel 16. In this way, it becomes possible to photograph the self-photographer with the camera 15. Also, it is possible to photograph through the through hole 12 by photographing means such as a camera installed at a distance behind the projector 1. The stand 21 used at this time has a shape for preventing the front of the photographing means from being blocked.
[0015] (Modified example) The present invention can also be implemented in the following aspects. · Make the light emitter 3 into a flat heart shape without an annular shape and without a space part.
[0016] · As shown in Fig. 6(b), support the projector 1 at the upper end of the column 32 of the tabletop electric stand 31 so as to be able to fluctuate and reverse back and forth. In this way, it becomes possible to take a self-portrait without using the stand 21 as shown in Fig. 1. Also, when not taking a self-portrait, in the light emission state of the light emitter 3, the projector 1 becomes the light emission illumination part of the tabletop electric stand 31.
[0017] · Make the light emitter 3 into a regular heart shape α or a shape wider in the left-right direction than the regular heart shape α. In this way, it is possible to make the heart shape reflected in the pupil wider than the regular heart shape α.
[0018] (Other technical ideas) The technical ideas grasped from the above embodiment are as follows. (A) The projector according to claim 1, wherein the light emitter 3 is flattened left and right with respect to the regular heart shape α. In this configuration, when the heart is reflected in the pupil, it has a shape that is the regular heart shape α or a heart shape close to the regular heart shape α.
[0019] (B) The projector according to claim 1, wherein the light emitter 3 is flattened left and right and the flatness ratio is 40 to 80 percent. In this configuration, when the light emitter 3 is reflected in the pupil, it has a shape that is the regular heart shape α or a heart shape close to the regular heart shape α.
[0020] (C) A projector set having the projector 1 according to claim 1 and a support member that supports the projector 1 in a standing state.
