<P>PROBLEM TO BE SOLVED: To provide an LED unit capable of emitting light to different directions and lessening the number of components and having high production effects at low cost. <P>SOLUTION: The LED unit 100 includes a primary reflection section 300 having a bottom face section 330 as an elongated bottom face section 330 (light-emitting face) having an LED line 211 wherein light-emitting LEDs 210 are linearly arranged in a longitudinal direction, and primary reflecting surfaces on both sides formed at an irradiation direction side of light from both side ends of the bottom face section 330 in a short-length direction and reflecting light emitted from the LEDs; and an auxiliary reflection section 400, which is a triangular pole-shaped auxiliary reflection section 400 having three sides and three side faces, arranged so as to make an opposing side section 420 as one side among three sides faces the LED line 211 and reflecting the light emitted from the LEDs 210 with both side faces (auxiliary reflecting surfaces 410a, 410b) of the opposing side section 420. <P>COPYRIGHT: (C)2013,JPO&INPIT |
