Title:
LIGHT EMITTING DIODE LUMINAIRE
Document Type and Number:
Japanese Patent JP2019091585
Kind Code:
A
Abstract:
To increase illuminance to merchandise while freezing power consumption, to prevent chips of light emitting diodes from being reflected in wrap covering the merchandise, and to prevent a light emitting diode luminaire from warping even when the light emitting diodes generate heat.SOLUTION: On an inside surface of a back part 10 of a long and translucent casing 2 whose cross section has a substantially triangular shape, a printed circuit board 6 is arranged on which a plurality of light emitting diodes 5 are mounted linearly. The light emitting diodes 5 of the printed circuit board 6 radiate light in the horizontal direction. A reflection plate 7 is arranged by inclining at a predetermined angle so as to reflect the light from the light emitting diodes 5 downward. In the measurement result, in the angle range of substantially 90°, illuminance has been increased compared to the previous one, and in the case of the angle of 0°, the illuminance has been increased by substantially 1.33 times.SELECTED DRAWING: Figure 5
