In astronomy, first light is the first use of a telescope (or, in general, a new instrument) to take an astronomical image after it has been constructed. This is often not the first viewing using the telescope; optical tests will probably have been performed in daylight to adjust the components.
Multicolored lighting method and apparatus
Illumination methods and apparatus, in which a first number of first light sources are adapted to generate first radiation having a first spectrum, and a second number of second light sources are adapted to generate second radiation having a second spectrum different than the first spectrum. In one example, the first number of the first light sources and the second number of the second light sources are different. In another example, a first intensity of the first radiation and a second intensity of the second radiation are independently controlled so as to controllably vary at least an overall perceivable color of generated visible radiation. In yet another example, a first control signal controls all of the first light sources substantially identically, and a second control signal controls all of the second light sources substantially identically.

Light source intensity control system and method
InactiveUS20100259182A1Electroluminescent light sourcesElectric light circuit arrangementControl signalControl system
The light source comprises one or more first light-emitting elements for generating light having a first wavelength range and one or more second light-emitting elements for generating light having a second wavelength range. The first light-emitting elements and second light-emitting elements are responsive to separate control signals provided thereto. A control system receives a signal representative of the operating temperature from one or more sensing devices and determines first and second control signals based on the desired colour of light and the operating temperature. The light emitted by the first and second light-emitting elements as a result of the received first and second control signals can be blended to substantially obtain the desired colour of light. The desired colour of light generated can thus be substantially independent of junction temperature induced changes in the operating characteristics of the light-emitting elements.
