Title:
LUMINAIRE
Document Type and Number:
Japanese Patent JP2015057756
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a luminaire capable of achieving both ambient lighting using an arbitrary lighting color and task lighting, while having excellent designability.SOLUTION: As a first lighting part 111 emits emission light from an LED 2 from a light guide plate 1, surface light emission is possible while achieving reduction in thickness, and satisfactory task lighting is achieved. Also, as the LED 2 and LEDs 52, 54 can be lighted independently, lighting of only the task lighting by the first lighting part 111 or the lighting of only the ambient lighting by a second lighting part 112 can be easily achieved. Furthermore, as the light emitted from the LEDs 52, 54 are made to go in the opposite side from the light emitted from the light guide plate 1, mixture of the ambient lighting light into the task lighting light is suppressed, and workability by the task lighting can be secured while securing color rendering properties of the ambient lighting. In addition, as a light emission color of the LED 2 and the LEDs 52, 54 can be set arbitrarily, various kinds of space rendering can be achieved.
