Document Type and Number:
Japanese Patent JP2014186928
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a lighting device which maintains good luminous efficiency of a semiconductor light emitting element by a relatively simple structure.SOLUTION: A lighting device includes: a mounting substrate 6 on which an LED 61 is mounted; and a light guide plate 9 which is disposed along a surface of the mounting surface 6 and guides an outgoing beam of the LED 61. A sealing member 8 is placed between the mounting substrate 6 and the light guide plate 9 so as to closely contact with the mounting substrate 6 and the light guide plate 9. The sealing member 8 shields the atmosphere around the LED 61 from outer air.
