The range B of the light-transmitting region 33 on the peripheral surface of the surface 48 also moves, so it seems that the peripheral portion of the decorative frame portion 46 always emits or shines with a higher luminosity than the decorative frame portion 46 .

In the illuminating device 10 with such a structure, the light-transmitting area 33 of the peripheral surface of the lampshade 15 is reflected on the reflective surface 48 of the decorative frame 19 arranged around the lampshade 15 when viewed from the light irradiation direction, so that the surrounding surface of the lampshade 15 can A lighting effect having a sense of brightness or sparkle can be obtained, thereby improving commerciality.

Furthermore, since the reflector 43 is provided with an incident surface 47 rising from the support 42 and positioned between the reflective surface 48 and the peripheral light-transmitting region 33 of the globe 15 , the support 42 can be made thin. In addition, whether the thickness of the decorative frame portion 46 of the support portion 42 is the same as the height of the reflection portion 43, or when the thickness of the decorative frame portion 46 of the support portion 42 is made thinner by providing the incident surface 47, the peripheral surface of the lampshade 15 is transparent. All the light areas 33 can be reflected on the reflective surface 48 , but when the incident surface 47 is provided and the supporting portion 42 is thinned, the material of the decorative frame 19 can be reduced and the weight can be reduced.

In addition, a diffusion material for diffusing incident light may be included in the decorative frame 19 . Even if the decorative frame 19 contains a diffusion material, the lighting effect of the decorative frame 19 with a sense of brightness or sparkle can be obtained through the reflective surface 48 .

In addition, prism processing may be performed on the reflective surface 48 of the decorative frame 19 . The reflective surface 48 after prism processing can diffuse the reflection direction of light, so that the brightness or sparkle around the lampshade 15 changes with the viewing direction of the lighting device 10 , thereby improving the lighting effect.

In addition, the illuminating device 10 is not limited to a circle, and the structure of the above-mentioned embodiment can also be applied to a polygon such as a square.
