PROBLEM TO BE SOLVED: To actuate a semiconductor light emitting device, without using any special booster circuit, etc. SOLUTION: The semiconductor light emitting device comprises a tubular fluorescent member (1), a semiconductor light emitting element (3) disposed in the member (1) and a plurality of outer leads (4, 5) which are fixed to both ends of the member (1) and electrically connected to the light emitting element (3). The outer leads (4, 5) comprise leading parts (4a, 5a) extending out of the member (1) and terminals (4b, 5b) which are disposed in the member (1) and electrically connected to the element (3). The member (1) has a light transmission to a light emitted from the element (3) and comprises a fluorescent substance for absorbing the light emitted from the element (3) to convert to other light emitting wavelengths. This actuates the light emitting element (3) to light at a low voltage, without needing a booster circuit generating high frequency noise. |
