Abstract:
PROBLEM TO BE SOLVED: To provide an LED unit capable of controlling light distribution with a relatively simple configuration and to provide a lighting fixture including the LED unit.SOLUTION: An LED unit 10 includes: a base 1; a light emitting device 3 arranged on one surface side of the base 1; a lighting device 2 for lighting the light emitting device 3; a connection terminal 4 for electrically connecting the light emitting device 3 and the lighting device 2; and a translucent cover 7 attached to the base 1 so as to cover the light emitting device 3. A wiring board 2a of the lighting device 2 is arranged to face a mounting board 3b of the light emitting device 3 in the thickness direction. The wiring board 2a has an opening 2aa penetrating in the thickness direction and controlling light distribution of light from the light emitting device 3. The connection terminal 4 applies an elastic force toward the direction in which the mounting board 3b and the wiring board 2a are separated from each other. The cover 7 supports the wiring board 2a and is configured so that the distance between the mounting board 3b and the wiring board 2a can be relatively displaced in the thickness direction of the wiring board 2a.SELECTED DRAWING: Figure 1
