Embodiment approach 1
[0068]FIG. 1 is a perspective view of a rotating light 100 according to the first embodiment. As shown in FIG. 1 , the rotating lamp 100 has a housing 16 including a transparent shade 12 and a main body (base) 13 . The shade 12 has a substantially hollow cylindrical shape. The lower surface of the globe 12 serves as an opening 12a that opens outward, and a threaded portion is formed on the inner peripheral surface of the opening 12a. The main body 13 is formed in a substantially hollow cylindrical shape. The upper surface of the main body 13 is an opening 13a that opens outward, and a threaded portion for screwing into the threaded portion formed in the opening 12a is formed on the outer peripheral surface of the opening 13a. The threaded portions formed in these openings 13 a and 12 a are screwed together, so that the globe 12 and the main body 13 are integrally formed to constitute the frame body 16 .
[0069] A round table 20 is arranged near the opening 12a and the open...
Embodiment approach 2
[0103] Embodiment 2 is demonstrated using FIGS. 8-16. FIG. 8 is a perspective view of a rotating light 200 according to the second embodiment. As shown in FIG. 8 , the rotating lamp 200 has an auxiliary reflector 50 arranged to face the reflector 5 . The auxiliary reflection mirror 50 includes a support portion 50a fixed to the upper surface 20c of the table 20, and a sub-reflection portion 50b provided at the front end portion of the support portion 50a.
[0104] Both the auxiliary reflector 50 and the light emitter 1 are arranged along the axis P of the reflective surface 5 a, and the light emitting diodes 34 in the light emitter 1 are arranged between the reflector 5 and the auxiliary reflector 50 .
[0105] FIG. 9 is a side cross-sectional view of the rotating lamp 200 shown in FIG. 8 . As shown in FIG. 9 , the sub-reflecting surface 50 c of the auxiliary reflector 50 arranged to face the reflector 5 is a curved surface curved in an arc shape. . The curved sub-reflectiv...
Embodiment approach 3
[0120] A rotating light 300 according to Embodiment 3 will be described with reference to FIGS. 17 to 20 .
[0121] FIG. 17 is a perspective view of a rotating lamp according to Embodiment 3. FIG. As shown in this figure 17, the revolving lamp 300 includes a frame body 16, a high-power LED60, a printed circuit board 2, a heat dissipation part 62, a reflector 61, and a power supply part 67; the above-mentioned high-power LED60 is disposed in the frame body 16 as a light source; A high-power LED 60 is arranged on the above-mentioned printed circuit board 2 ;
[0122] The globe 12 includes a circular upper wall 12b and a peripheral wall 12c formed on the peripheral edge of the upper wall 12b. The heat dissipation portion 62 is directly fixed on the upper wall 12b by using a plurality of protrusions 63 . The heat dissipation portion 62 is formed in a circular plate shape, and is fixed slightly away from the upper wall 12b. Furthermore, the printed circuit board 2 is fixed to th...
