Title:
LIGHTING PANEL AND LIGHTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2007/026696
Kind Code:
A1
Abstract:
A lighting panel capable of forming at a long lighting distance a lighting area with
a constant flat illuminance distribution at a high illuminance with power saved.
The lighting panel (100) provided with a plurality of linear light source units
(200), wherein the linear light source units (200) comprise light emitting units
having a plurality of light emitting diodes linearly arranged on a substrate, first
reflection units respectively provided on the light outgoing side of the light
emitting unit to correspond to respective plurality of light emitting diodes
and consisting of parabolic surfaces of which the focusing positions coinciding
with the light emitting surfaces of the light emitting diodes, and second reflection
units arranged in pairs on the further light outgoing sides of the first reflection
units and in parallel to the arranging direction of the light emitting diodes
across the light emitting diodes and having flat reflection surfaces for reflecting
lights from the light emitting diodes toward the light outgoing sides, the linear
light source units (200) being arranged annularly on a module panel (1).
