    摘要: An LED illumination system includes a DC power supply, at least two LED illumination lamp sets and at least two power circuits corresponding to the LED illumination lamp sets. The DC power supply provides sufficient electric power for the LED illumination lamp sets and is connected to the LED illumination lamp sets via the power circuits. The invention supplies electric power required by the LED illumination lamp sets via a single DC power supply without an extra DC power supply, hence the cost is lower. Moreover, the DC power supply is located remote from the LED illumination lamp sets, hence high temperature generated by the DC power supply does not affect lighting and lifespan of the LED illumination lamp sets. The hazard of electric shock by inadvertently touching the AC power source while replacing lamps in the LED illumination lamp sets can also be avoided to improve safety.

    摘要: A light emitting diode includes a first conductivity type semiconductor substrate, a basic AlGaInP double heterostructure and two window layers of second conductivity type semiconductor. A layer of first conductivity type AlGaInP an undoped AlGaInP layer and a layer of second conductivity type AlGaInP form the double heterostructure. The AlGaInP layers are epitaxially grown above the substrate sequentially. The window layers contain one layer of GaAs and the other layer of GaP. The first window layer is formed by epitaxially growing GaAs over the AlGaInP heterostructure. The second window layer is formed by growing GaP directly on the first window layer using either OMVPE or vapor phase epitaxy (VPE) technology. The inclusion of a GaAs window layer increases current spreading and, hence, the efficiency of the device. The yield rate of manufacturing the light emitting diode is also increased because the quality of GaP layer surface is improved.

    摘要: A light emitting diode includes a first conductivity type GaAs substrate having a second conductivity type region as a current blocking layer. A first conductivity type distributed Bragg reflector layer is formed on the GaAs substrate. An AlGaInP double heterostructure including a lower cladding AlGaInP layer of the first conductivity type, an undoped active AlGaInP layer, and an upper cladding AlGaInP layer of the second conductivity type is grown on top of the distributed Bragg reflector layer. The undoped active AlGaInP layer can also be replaced by a multi-layer quantum well structure of AlGaInP or a strained multi-layer quantum well structure of AlGaInP. A second conductivity type layer of low energy band gap and high conductivity material is formed on the AlGaInP double heterostructure. A GaP window layer of the second conductivity type is then formed on top of the low energy band gap layer.

    摘要: A light emitting diode is epitaxially grown on a semiconductor substrate. A lower cladding layer is grown on the substrate and doped to have n-type conductivity. An active layer is deposited on the lower cladding layer, and a p-type upper cladding layer is deposited on the active layer. A relatively thin lower window layer is then deposited on the upper cladding layer, and doped with a first p-type dopant material. A relatively thick upper window layer is then deposited on the lower window layer, and doped with a different p-type dopant material. The layer with a dopant different from the principal portion of the window serves to limit diffusion of dopant through the active layer. The dopant in the diffusion limiting layer can diffuse in both directions, thereby reducing the driving force of diffusion. As a result, the p-type dopant intersects a steep portion of the concentration gradient of n-type dopant quite near the interface between the lower cladding layer and active layer, resulting in high light output power. A diffusion limiting layer having a different dopant than a substrate may be used for forming a LED with a p-type substrate and an n-type layer near the upper face.
