Abstract
In a light emitting diode device, providing a light beam with limited dispersion and primarily to be used in a so called red dot sight for a weapon, a light-impermeable mask (14) with a hole (14′) for light is arranged directly on a light emitting surface of the light emitting diode element (13) in the device.
Claims18

- (a) a light emitting element including a light emitting diode element;
- (b) a light impermeable mask deposited directly onto a surface of said light emitting diode element by at least one of a vaporization and sputtering thereby preventing loss of light by dispersion before it reaches and leaves the mask;
- and
- (c) an aperture formed through said light impermeable mask.
