  • Patent number: 7938557
    Abstract: A light source and a method for operating the same are disclosed. The light source includes a light emitter and a controller. The light emitter generates light in response to a control signal coupled thereto. The light emitter is characterized by an age related to the amount of light that has been cumulatively generated by the light emitter, the generated light for a given control signal changing with the age. The controller measures the age of the light emitter and generates the control signal based on the desired light intensity and the measured age of the light emitter. In one embodiment, the controller stores an age value for the light emitter, and the controller determines the control signal in response to an input signal specifying a desired light intensity from the light emitter, the controller updating the age value each time the control signal is determined.

  • Patent number: 7522211
    Abstract: A studio light having first and second light output regimes, and adjustable color temperature. The color temperatures of the first and second light output regimes may be different. The light module includes one or more emitters of light of at least two different colors. An external signal causes the light module to switch from a first light output regime to a second, higher intensity light output regime, and back to the first light output regime.

  • Patent number: 7315048
    Abstract: In one embodiment, light emitted by a plurality of solid-state light emitters is mixed by mounting the plurality of solid-state light emitters on a transparent to translucent substrate so that they primarily emit light away from the substrate. The light emitters are then covered with a transparent to translucent encapsulant; and the encapsulant is coated with a reflective material that reflects light emitted by the light emitters toward the substrate. Related apparatus is also disclosed.

  • Patent number: 7284871
    Abstract: A flash module has a first light-emitting diode (“LED”) optically coupled to a first lens having a first viewing angle, and a second LED optically coupled to a second lens having a second viewing angle. The second viewing angle is greater than the first viewing angle. A first control signal line coupled to the first LED allows selectively activating the first LED. A second control signal line coupled to the second LED activates the second LED.
