  • Patent number: 7837371
    Abstract: A light source, such as for a projection system, having a plurality of semiconductor chips and at least two different, electromagnetic-radiation-emitting chip types with different emission spectra, each semiconductor chip having a chip coupling-out area through which radiation is coupled out. Furthermore, the light source has a plurality of primary optical elements, each semiconductor chip being assigned a primary optical element, which in each case has a light input and a light output and reduces the divergence of at least part of the radiation emitted by the semiconductor chip during the operation thereof. The semiconductor chips with the primary optical elements are arranged in at least two groups that are spatially separate from one another, with the result that the groups emit separate light cones during operation of the semiconductor chips. The separate light cones of the groups are superposed by means of a secondary optical arrangement to form a common light cone.

  • Patent number: 7824058
    Abstract: In a wake-up apparatus for waking up a sleeper by light stimulus, it wakes the sleeper comfortably without feeling glare. A lighting device has a first lighting unit at a position that a light emitting face cannot be observed directly by the sleeper, and a second lighting unit at a position that a light emitting face can be observed directly by the sleeper. A control device activates the lighting device a predetermined time before a preset wake-up time so as to vary illuminance of light emitted from the lighting device in an order of low illuminance, middle illuminance and high illuminance, to light only the first lighting unit in a low illuminance condition and a middle illuminance condition, and to light both of the first lighting unit and the second lighting unit in a high illuminance condition, and quickly varies from the middle illuminance condition to the high illuminance condition.

  • Patent number: 7815335
    Abstract: A uni-planar focal adjustment system involving no reflector housing rotation for use in high-intensity discharge (HID) lighting systems. A simple mechanical drive system allows a user to manually adjust the focal point by turning a focal adjustment ring, which in turn moves a HID lamp assembly back and forth along an optical axis relative to a stationary reflector. The system utilizes only linear motion along the optical axis and does not involve rotational reflector movement. The system allows for a significantly smaller reflector through-hole, which increases the percentage of HID generated light capable of being reflectively used in the focused light beam. Finally, the focal adjustment system allows for separation of the HID lamp assembly inductor/igniter coil from the remaining ballast circuit board components, thereby further improving heat management of the lighting system, while maintaining the optimum alignment of the lamp in regards to the parabolic optic and increasing light production efficiency.
