[0021] Please refer to Figure 3 As shown, it is a bottom view of a partial structure of a high-efficiency light source fixed-point lighting system in one embodiment of the present invention. Figure 3 The illustrated high-efficiency light source fixed-point lighting system includes a reflective structure (not labeled), which includes three ellipsoidal reflectors 310, one LED 320, and three light-emitting surfaces 330. Each ellipsoidal reflector 310 has a first focus 312 and a second focus 314. The first focus 312 of the three ellipsoidal reflectors 310 is a common focus. The LED 320 is located at this common focus (i.e., the first focus 312). The three light-emitting surfaces 330 correspond one-to-one to the three ellipsoidal reflectors 310, and each light-emitting surface 330 is located at the second focus 314 of the corresponding ellipsoidal reflector 310. The ellipsoidal reflectors 310 can be made of aluminum or other reflective materials.

[0022] exist Figure 3 In the specific embodiment shown, the three ellipsoidal reflectors 310 are of the same size; the three ellipsoidal reflectors 310 are spliced together to form a reflective structure (not marked); and the openings of the three ellipsoidal reflectors 310 are oriented in the same direction.

[0023] Please refer to Figure 4 As shown, the present invention is as follows in one embodiment Figure 3 A cross-sectional view of a high-efficiency light source spot lighting system is shown. Figure 4The illustrated high-efficiency light source fixed-point lighting system also includes a bracket 340, a first through-hole 350, a printed circuit board assembly (PCBA) 360, and three second through-holes 370. The bracket 340 covers the openings of the three ellipsoidal reflectors 310. The first through-hole 350 is located at a common focus (i.e., first focus 312) and passes through the bracket 340. The PCB 360 is disposed at the first through-hole 350 of the bracket 340. An LED 320 is mounted on the PCB 360, and the LED 320 faces the three ellipsoidal reflectors 310. The three second through-holes 370 correspond one-to-one to the three ellipsoidal reflectors 310. Each second through-hole 370 is located at the second focus 314 of the corresponding ellipsoidal reflector 310 and passes through the bracket 340. Each second through-hole 370 forms a light-emitting surface 330 located at the second focus 314 of the corresponding ellipsoidal reflector 310.

[0024] Since the ellipse itself has the characteristic of double focus, that is, the light at one focus of the ellipse will be emitted from the other focus after being reflected by any position on the surface of the ellipse, and Figure 3 In the specific embodiment shown, the three ellipsoidal reflectors 310 are of the same size, the LED 320 is located at the common focus of the three ellipsoidal reflectors 310 (i.e., the first focus 312), and the three light-emitting surfaces 330 are respectively located at the other focus of the three ellipsoidal reflectors 310 (i.e., the second focus 314). Therefore, when the light from the LED 320 is irradiated onto the three ellipsoidal reflectors 310, each ellipsoidal reflector 310 will collect one-third of the light emitted by the LED 320 (i.e., the light emitted by the LED 320 will be evenly divided into three parts and irradiated onto the three ellipsoidal reflectors 310 of the reflective structure), and then reflect the light from the LED 320 to the light-emitting surface 330 located at the other focus (i.e., the second focus 314) of the ellipsoidal reflector 310, thereby achieving the effect of one LED illuminating three locations. For details, please refer to Figure 5 As shown, the present invention is as follows in one embodiment Figure 4 The light direction diagram of the high-efficiency light source fixed-point lighting system is shown.

[0025] Please refer to Figure 6 As shown, the utility model is as follows in the first embodiment Figure 3 The top view of the high-efficiency light source fixed point lighting system is shown. Figure 7 As shown, it is a top view of the high-efficiency light source fixed-point lighting system in the second embodiment of the present invention. Figure 6 In the high-efficiency light source fixed-point lighting system shown, the reflective structure includes three ellipsoidal reflectors 310 of the same size; Figure 7In the illustrated high-efficiency light source fixed-point lighting system, the reflective structure includes six ellipsoidal reflectors 310 of equal size. In other embodiments, the number of ellipsoidal reflectors 310 may be two, four, five, seven, or more. In other words, in the high-efficiency light source fixed-point lighting system provided by the present invention, the reflective structure includes no limitation on the number of ellipsoidal reflectors 310, and a different number of ellipsoidal reflectors 310 may be defined based on actual needs.

[0026] Please refer to Figure 8 As shown, it is a top view of the high-efficiency light source fixed-point lighting system in the third embodiment of the present utility model. Figure 8 In the illustrated high-efficiency light source fixed-point lighting system, the reflective structure includes three ellipsoidal reflectors 310 of different sizes. In other words, in the high-efficiency light source fixed-point lighting system provided by the present invention, the multiple ellipsoidal reflectors 310 included in the reflective structure can be of different or uniform sizes. The larger the ellipsoidal reflector 310, the higher the brightness of the light-emitting surface 330 at its second focal point 314.

[0027] Please refer to Figure 9 As shown, it is a bottom view of a partial structure of a high-efficiency light source fixed-point lighting system in another embodiment of the present invention; please refer to Figure 10 As shown, the present invention is as follows in one embodiment Figure 9 The cross-sectional view of the high-efficiency light source fixed-point lighting system is shown. Figure 3 and Figure 4 Compared with the high-efficiency light source fixed-point lighting system shown, Figure 9 and Figure 10 The illustrated high-efficiency light source fixed-point lighting system can be viewed as follows: the number of ellipsoidal reflectors 310 approaches infinity, and the light-emitting surfaces 330 of the second focal points 314 of all ellipsoidal reflectors 310 form an annular light-emitting surface 380. In other words, when the number of ellipsoidal reflectors 310 approaches infinity, the high-efficiency light source fixed-point lighting system provided by the present invention produces a ring-shaped lighting effect.

[0028] In summary, the present invention provides a high-efficiency light source fixed-point lighting system, which includes: a reflective structure (unlabeled), the reflective structure (unlabeled) including n ellipsoidal reflectors 310, each ellipsoidal reflector 310 having a first focus 312 and a second focus 314, and the first focus 312 of the n ellipsoidal reflectors 310 is a common focus; an LED 320, which is located at the common focus (i.e., the first focus 312); n light-emitting surfaces 330, the n light-emitting surfaces 330 corresponding one-to-one to the n ellipsoidal reflectors 310, and each light-emitting surface 330 is located at the second focus 314 of the corresponding ellipsoidal reflector 310, wherein n is a natural number greater than or equal to 2. In this way, the present invention can disperse the light emitted by an LED to multiple light-emitting positions that need to be fixed-point illuminated by using a reflective structure, thereby ensuring that the multiple light-emitting positions that need to be fixed-point illuminated are all illuminated.

[0029] In one embodiment, n ellipsoidal reflectors 310 are spliced together to form a reflective structure (not labeled); the openings of the n ellipsoidal reflectors 310 are oriented in the same direction.

[0030] In one embodiment, the high-efficiency light source fixed-point lighting system provided by the present invention also includes: a bracket 340, which covers the openings of the n ellipsoidal reflectors 310; a first through hole 350, which is located at the common focus (i.e., the first focus 312) and passes through the bracket 340; a printed circuit board 360, which is arranged at the first through hole 350 of the bracket 340, and the LED 320 is mounted on the printed circuit board 360, and the LED 320 faces the n ellipsoidal reflectors 310; n second through holes 370, the n second through holes 370 correspond one-to-one to the n ellipsoidal reflectors 310, each second through hole 370 is located at the second focus 314 of the corresponding ellipsoidal reflector 310 and passes through the bracket 340, and each second through hole 370 is formed with a light-emitting surface 330 located at the second focus 314 of the corresponding ellipsoidal reflector 310.
