Abstract: A shining tray includes a main body, several light producing devices, light guiding members, and a sealing member; the main body has an raised edge, and an outer surrounding portion encompassing the raised edge and extending downwards from an upper end of the raised edge such that a holding room is formed between the raised edge and the outer surrounding portion; the light producing devices are held in the holding room; the light guiding members are held in the holding room, and abut the light producing devices; the sealing member is tightly held in the holding room so as to prevent water from leaking into the holding room and to fix the light producing devices as well as the light guiding members in position.
