Abstract
A lighting device includes an LED, a light guiding member, and a mask member. The light guiding member has a cut to provide a directivity to light emitted from the LED. The cut is provided at a position corresponding to the LED on an emission surface side of the light guiding member. The mask member is disposed on an emission surface side of the cut to block the light emitted from the LED.
Claims22
A lighting device comprising:
- an LED as a light source;
- a light guiding member formed of a plate-shaped member having a uniform thickness and having a cut formed to provide a certain directivity to emitted light from the LED;
- wherein the cut is formed at a position corresponding to the LED, at an emission surface side of the light guiding member;
- a case having an opening at an emission surface side thereof to surround the light guiding member;
- a lens configured to cover the opening of the case;
- and
- a mask member configured to block the emitted light from the LED is disposed on the lens on an emission surface side of the cut, wherein
- the light guiding member includes an outer peripheral edge having:
- a step portion formed on the emission surface side of the light guiding member;
- and
- an inclined surface formed on a side opposed to the emission surface side of the light guiding member, and
- the lens having a bulging portion formed at a peripheral edge thereof, the bulging portion projecting towards the light guiding member and directly contacting the step portion of the outer peripheral edge of the light guiding member.
