Lighting apparatus with enhanced capability of removing heat |
| 摘要 |
A lighting apparatus comprises an LED-mounted substrate and an exhauster. The substrate has a flat area as well as one or more raised areas of trapezoidal cross section which each form a passage thereunder. LEDs are mounted on the raised areas. When the LED-mounted substrate is installed on a wall, the passages are enclosed by the wall. The exhauster removes the heat from the LEDs by drawing out the air going through inside the passages.
