The nozzle has a nozzle head (7) that is arranged inside a pot-shaped housing (8), and extended to front-side from the housing. A cavity (10) is formed between the housing and the nozzle head, on which LEDs (11,12) are circularly arranged, while partially closed by a front-panel (2) made of stainless steel with a polished surface. The front-panel is annularly formed with a concave or convex surface. An upper annular gap (6) is formed between the front-panel and the nozzle head, and a lower annular gap (4) is formed between the front-panel and the housing. |
