  • Light emitting diode
    Patent number: 8007136
    Abstract: Disclosed is a light emitting diode (LED). The LED includes a light emitting chip, a reflector formed with an annular groove in an inner surface thereof and surrounding the light emitting chip, and a lens engaged with the groove of the reflector. An inner diameter of a lens insertion portion of the groove is smaller than an outer diameter of the lens, so that the lens can be engaged with the groove through elastic deformation. Since the separately manufactured lens is engaged with and coupled into the groove of the reflector, the lens can be fixed through a simple process and aligned without an error. Since the lens is engaged with the groove of the reflector, the lens is prevented from being easily separated. In addition, since there is no need for the use of an adhesive, it is possible to prevent degradation of the reliability of the LED.

  • Method and apparatus for creating high efficiency even intensity circular lighting distributions
    Patent number: 7972029
    Abstract: A surface mount LED lamp includes a central first section having a flat circular window that provides a direct view window to the source energy and having an angle equal to the total intended output viewing angle of the LED lamp thereby providing a smooth and relatively undistorted output intensity distribution. The window allows the energy from the wide angle LED source to exit the lamp with minimal distortion, creating a smooth generally cosine shaped light distribution through the intended viewing angle of the device. A second outer section has both refractive and internally reflective surfaces for the purpose of collecting the wider output angle light from the LED source thereby adding to the intensity at the outer edges of the distribution.
