Methods and apparatus for generating essentially white light. In one example, a white light generating apparatus comprises at least one first white LED characterized by a first spectrum, and at least one second white LED characterized by a second spectrum, wherein the first spectrum is substantially different than the second spectrum.
摘要:
Methods and apparatus for illumination of liquids in a variety of environments. In one example, multi-color LED-based light sources are employed to achieve a wide range of enhanced lighting effects in liquids. In another example, a pool or spa is illuminated by one or more multi-color light sources that may be employed as individually and independently controllable devices, or coupled together to form a networked lighting system to provide a variety of programmable and/or coordinated color illumination effects in the pool or spa environment.

Methods and systems are provided for LED modules that include an LED die integrated in an LED package with a submount that includes an electronic component for controlling the light emitted by the LED die. The electronic component integrated in the submount may include drive hardware, a network interface, memory, a processor, a switch-mode power supply, a power facility, or another type of electronic component.
摘要:
Lighting apparatus and methods employing LED light sources are described. The LED light sources are integrated with other components in the form of a luminaire or other general purpose lighting structure. Some of the lighting structures are formed as Parabolic Aluminum Reflector (PAR) luminaires, allowing them to be inserted into conventional sockets. The lighting structures display beneficial operating characteristics, such as efficient operation, high thermal dissipation, high output, and good color mixing.
摘要:
Methods and apparatus in which at least one first LED generates first radiation having a first spectrum, and at least one second LED generates second radiation having a second spectrum different than the first spectrum. One or more controllers control at least one of the first radiation and the second radiation so as to control at least a color temperature of visible radiation. In one example, one or more sensors monitor at least one characteristic of sample radiation and provide one or more sensor signals to the one or more controllers, which in turn control at least the color temperature of the visible radiation based at least in part on the at least one sensor signal. In various implementations, the sample radiation may be ambient illumination (e.g., natural-light and/or light from other light sources), may be the visible radiation itself (e.g., to provide feedback to the one or more controllers), or generally any desired lighting condition to simulate.
摘要:
Methods and apparatus for controlling illumination. In one example, one or more multi-color light sources are controlled based on one or more interruptions of power supplied to the light source(s). In another example, a pool or spa is illuminated by one or more multi-color light sources that may be employed as individually and independently controllable devices that may be controlled based on one or more interruptions in power. In another example, the selection of a particular illumination program for such light sources (e.g., by one or more interruptions in power) is indicated to a user via the radiation generated by the light sources.
