  • Publication number: 20050082973
    Abstract: A light emitting diode includes a frame, which has fist leg, a second leg, a chip bonded to the top end of the first leg, and an electrode wire soldered between the chip and the top end of the second leg, and a resin layer, which packages the chip and the electrode wire and has a fluorescent layer evenly distributed in between a first resin layer and a second resin layer thereof for enabling light source from the chip to be fully mixed with the color of the fluorescent material in the fluorescent layer to produce the designed color of light.

  • Publication number: 20050077535
    Abstract: A LED manufacturing process includes multiple compounding potting procedures to form a fluorescent layer between a first resin layer and a second resin layer, keeping the chip and the electrode wire embedded with a part of the frame in the second resin layer and spaced from the fluorescent layer at a distance.

  • Publication number: 20050073827
    Abstract: The light emitting diode display device of the present invention comprises a circuit module and a frame. An upper and a lower layer of circuit board, forming a protruded circuit board, constitute the circuit module. The protruded circuit board has at least two sides having differential length and thereby forming an indention. Each button flange of the frame is fit into the indention to enable the sidewall of the frame come in contact with the upper and the lower circuit board, thus the welding efficiency can be substantially increased. Further, conductive glue or a metallic pin is used to fit the frame onto the protruded circuit board, or a tin solder material is used to weld the elements for jointing elements thereof. Accordingly, the sidewall of the frame will not flit up or become loose easily. Thus, due to the steady assembly, the structure of the display device is not only reinforced but also resin-leakage problem can be resolved.

  • Publication number: 20040114367
    Abstract: A light emitting diode (LED) light bulb includes a lamp holder and a lamp body; wherein the light body is disposed on the top plane of the lamp holder; the present invention is characterized that the lamp body is composed by more than two circuit boards; a plurality of LED light bulbs are disposed in parallel or in tandem on each circuit board such that the light source of the LED extensively emits toward all the directions; applying the abovementioned structure accordingly, the LED light bulb saves the electricity and has a longer useful life so as to effectively save the cost.
