  • Patent number: 9107251
    Abstract: A wake-up lamp system (100; 1000) comprises: a light source (130) having a nominal light output intensity (Lmax); and a control device (110) for controlling the light source, the control device receiving a clock signal from a clock device (120). The control device, when operating in a wake-up mode, controls the light source such that its light output intensity is gradually increased from a minimum intensity value (Lmin) to a maximum intensity value (Lmu) and such that the color point of the light output is gradually changed to travel a predefined chromaticity path, with the position of the color point on said chromaticity path being set as a function of the light output intensity. Said chromaticity path has a starting point having a color temperature between 400K and 1500K associated with the minimum intensity and an end point having a color temperature higher than 2700K associated with the nominal intensity.

  • Patent number: 6672742
    Abstract: A candle shade includes a sleeve adapted to receive a top end of a candle and a shade element coupled to the sleeve and surrounding the candle adjacent the top end. The sleeve has at least one spacing element on its interior surface to space the sleeve from the candle and reduce contact area therebetween. A stop is also provided on the sleeve to inhibit the sleeve from travelling down the candle beyond the top end.

  • Patent number: 5327331
    Abstract: A method of reducing the resistance of a sleeping mammal to arising at a preselected wake up time by exposing the mammal to at least one source of artificial light for a period of exposure of at least about 0.5 hour and no longer than about 8 hours before the preselected wake up time. The intensity of the artificial light may increase during the period of exposure. an apparatus for carrying out the method comprises a normally deacutated source of artificial light capable of illuminating a mammal, comprising a plurality of electric lamps, a control device, such as a timer, for signalling the commencement of a period of exposure preceding the mammal's preselected wake up time and an increase in illumination intensity during the period of exposure, after its commencement. The apparatus further features circuitry and a power supply, responsive to the control device, for actuating one lamp in response to the commencement signal, and for actuating additional lamps later during the period of exposure.

  • Patent number: 4566055
    Abstract: An improved candle holder in which the lens is trapped within elastic elongated bars that space the lens from the rigid metallic cover and frictionally hold the lens in an extended and retracted position. Viewing windows are provided for seeing the height of the unburned candle. A brandy glass attachment is provided for the top of the holder.
