  • Patent number: 8039849
    Abstract: An LED module to realize light source performance as desire is comprised of multiple LEDs, a light-emitting chip of each LED being disposed in a carrier on a substrate; conduction circuits with different polarities being provided perimeter to the carrier on the substrate; golden plate wire connecting the chip and circuits; carrier being filled with fluorescent material before encapsulation; a slope being formed on the inner wall of the carrier; and the light-emitting angles varying depending on inclination carrier or the encapsulating height.
    Type: Grant

  • Patent number: 8021006
    Abstract: A LED array flash for cameras includes a LED array and a controller. The LED array consists of at least one LED light source with first order lens. The LED light source may be further covered with a second order lens. Thus an oblong or round distribution pattern with uniform light intensity is emitted. The controller is used to control flash modes such as low brightness continuous lighting or high brightness pulse lighting with lighting time control so as to save power and avoid overheating.

  • Patent number: 7780313
    Abstract: A package structure for light emitting diode (LED) comprises a base, an LED die, an optical lens and a lens holder. The base comprises at least one holder cavity formed on its surface and at least one chase formed on its side surface. The lens holder comprises an opening, at least one holder stem and at least one wedge. The optical lens is arranged between the lens holder and the base, and also through the opening. The lens holder is fastened on the base by wedging the wedge with the chase and positioned on the base by embedding the holder stem into the holder cavity to enhance the positioning between the optical lens and the base, such that the optical lens can generate a desired light pattern. Therefore, the required time of a packaging process can be reduced, and the lens holder can be removed simply for replacing the optical lens, so the objective of changing the light pattern quickly can be achieved.
