A transparent sheet which has a smooth inner surface opposite to the circuit board and a coarse outer surface to prevent reflection of the sunshine, is provided outside the circuit board. A panel with a plurality of apertures to respectively correspond to the groups of LEDs is mounted outside the transparent sheet. Waterproof silica gel is spread over joints between the panel and the housing.
