  • Publication number: 20140293594
    Abstract: A lamp structure includes a base, a side-emitting light source, first and second reflecting portions. The base includes a central protrusion portion extending from the base. The side-emitting light source is disposed on a side surface of the central protrusion portion and configured to emit a light beam. The first reflecting portion includes a first reflective curved surface, and a portion of the light beam is reflected thereby and then is directly emitted out. The first reflecting portion is disposed between the central protrusion portion and the second reflecting portion. The second reflecting portion includes a second reflective curved surface adjacent to the first reflective curved surface, and the other portion of the light beam is reflected thereby and then is directly or indirectly emitted out. The first reflective curved surface has a radius of curvature less than that of the second reflective curved surface.

  • Patent number: 7985003
    Abstract: A forming mold of a light-emitting member includes a frame, an upper mold and a lower mold, and the frame is provided with carriers, pins and supporting portions. The upper and lower molds match with each other to provide a forming space for the base of the light-emitting member. The forming space contains the carriers and a part of the supporting portions. One or more projections are disposed at the position where the brinks of the upper and lower molds contact the supporting portions. After injection molding, the burrs formed by a plastic material along the supporting portions can be concealed in the recesses that are formed corresponding to each of the projections, thereby reducing the influence of the burrs on the external size of the base.

  • Patent number: 7615799
    Abstract: A light-emitting diode (LED) package structure including an encapsulant, a carrier, and an LED chip is provided. The encapsulant has a cavity located in a front end of the encapsulant. The carrier includes a die pad, a heat spreader, and a plurality of leads. The die pad is disposed on the encapsulant and located in the cavity. The heat spreader is connected with the die pad, and passes through the encapsulant to extend outside the cavity, and further extends toward a rear end of the encapsulant. The leads pass through the encapsulant and extend outside the cavity. The LED chip is disposed on the die pad, and is electrically connected to the leads. Heat generated when the LED chip emits light is conducted to the heat spreader via the die pad, so as to conduct the heat outside the encapsulant, and to further reduce the temperature of the LED chip.
