  • Device and method for emitting light with increased brightness using diffractive grating pattern
    Publication number: 20050036319
    Abstract: A device and method for emitting light with increased brightness utilizes a lamp having a diffractive grating pattern. The diffractive grating pattern diffracts incident light that originates from a light source toward a light output region of the lamp. The diffraction of the incident light causes more of the light to impinge the light output region of the lamp at desired angles. This reduces the angular distribution of the light emitted from the light output region as output light. The reduction in angular distribution of emitted light results in an increased brightness of the device.
