  • Publication number: 20160153909
    Abstract: An inspection apparatus is capable for inspecting at least one light-emitting device. The inspection apparatus includes a working machine and an inspection light source. The inspection light source is disposed on the working machine and located above the light-emitting device. A dominant wavelength of the inspection light source is smaller than a dominant wavelength of the light-emitting device so as to excite the light-emitting device and get an optical property of the light-emitting device.

  • Patent number: 8963437
    Abstract: A dimming system is composed of a dimmer having switchable power modes and at least one lighting device. When the dimmer is in a non-dimming bypass mode, an input power is directly transmitted to the at least one lighting device with the dimmer being bypassed so that the circuit in the dimmer consumes no power. When the dimmer is in a dimming mode, an output selector of the dimmer outputs a dimming output power having a dimming command therein to each one of the at least one lighting device for each lighting device to decode the dimming command embedded in the dimming output power and perform a dimming operation according to the dimming command. As the dimming operation lasts briefly, the power consumed by the dimmer is extremely small. Accordingly, no heat dissipation issue arises and the present invention is applicable to all sorts of high power lighting devices.

  • Patent number: 8278179
    Abstract: A method of forming a semiconductor structure includes providing a substrate including a fin at a surface of the substrate, and forming a fin field-effect transistor (FinFET), which further includes forming a gate stack on the fin; forming a thin spacer on a sidewall of the gate stack; and epitaxially growing a epitaxy region starting from the fin. After the step of epitaxially growing the epitaxy region, a main spacer is formed on an outer edge of the thin spacer. After the step of forming the main spacer, a deep source/drain implantation is performed to form a deep source/drain region for the FinFET.
