Zusammenfassung:	PROBLEM TO BE SOLVED: To effectively increase the optical output of a flash module using LEDs. SOLUTION: A plurality of LEDs are packaged individually with their specific domes (lenses). Each of LEDs, which is covered with its individual dome or is formed like a dome shape, emits a different monochromatic light. A white-colored optical output is derived by mixing those light colors. Alternatively, a white-colored optical output may be generated by mixing a phosphor in each dome. To further increase the optical output, a reflector can be additionally provided.
