Energy-saving lamp including a photo diode

摘要: An ernergy-saving lamp including a photo diode having head (10), receiving body (20), an outer shell (30), cover (40) and sensor (50). Projections indents are provided on the inner circumference (21) of said body, base (60) circuit block (70). The lamp-tube (80) is fixed (60); screw thread (62) wire opening (61). (50) at end (72), respective projections lower its (62). includes energy-saving photocell thereon through IC. with smaller diameter (30) (32). Between clipping connection. responding to brightness controls switch-on/switch-off state.
