  • Lighting device for forming pattern
    Patent number: 8449148
    Abstract: The present invention is capable of irradiating a desired figure, a character and the like onto an object with a simple configuration and further capable of easily changing the figure, the character and the like, and includes an LED light source, a first refractive element adapted to refract light emitted from the LED light source to form an image of a light emitting shape when viewed in an optical axis direction of the LED light source at a predetermined position and a casing accommodating the LED light source and the first refractive element and having a light outgoing aperture for emitting the light applied from the first refractive element to the outside.
    Type: Grant
