４を引上げる。Next, the operation of the above embodiment will be explained. The substrate 4 of the reflector is dipped in a silicate solution (not shown) with the peripheral edge 2 of the light projection opening facing downward. This is because, when facing downward, the solution does not accumulate inside, and it is easier to hold the solution during movement during the process. Next, the substrate 4 is pulled up from the solution.

した場合でも容易に落とすことが可能となる。The solution flows down along each of the inner and outer surfaces of the substrate 4 and adheres to these surfaces in the form of a film, and the solution on the outer surface reaches the curled portion 1. However, since a void 5 is formed at least on the bottom surface of this curled portion 1, the solution is discharged from this void 5. Therefore, since the solution does not accumulate in the curled part 1, in the next firing process,
Since the curled part 1 does not become cloudy due to foaming, or crack or peel off in this part, it is possible to form the glass film 3 on the surface of the substrate 4 without deteriorating the appearance. can. Once the glass film 3 is formed, dirt is less likely to adhere to this reflector, and even if dirt does adhere, it can be easily removed.

Alternatively, as shown in FIG. 7, it may be a circular hole. Moreover, although the reflector has a circular light projection aperture in the above embodiment, it is not limited to a circular shape, and may have a rectangular light projection aperture. Furthermore, although the overall shape of the reflector was bowl-shaped in the above embodiment, it may be rectangular. Roughly speaking, although the curl portion 1 was directed outward in the above embodiment, it may be directed inward.

This is a reflector characterized by having voids formed at multiple locations. Therefore, during the process of forming a glass film, a glass material solution such as a silicate solution does not accumulate in the curled portion.
Therefore, no bulges, cloudiness, cracks, etc. occur in the curled portion during firing, so deterioration of the appearance can be prevented. Moreover, since the second invention is a lighting fixture having the reflector of the first invention, it is possible to obtain a lighting fixture that is hard to get dirty, easy to clean, and has a good appearance.
