    摘要: A display apparatus 200 includes a substrate 219 and a number of light emitting diodes (LEDs) 202 coupled to the substrate. An optical element 207 such as a shroud or an integrator rod is located adjacent to at least one of the LEDs. In operation, the optical element and the LEDs are movable relative to one another so that the optical element is adjacent to different ones of the LEDs at different times.

    摘要: A method and apparatus for controlling a lamp. A timer (106) reads a rated safe life value from a memory (102) associated with a lamp in a lamp module (104). The memory (102) in the lamp module (104) contains a series of locations in which the rated safe life of the lamp has been stored, and a series of locations for storing the elapsed on time of the lamp. The timer controller (106) reads the series of locations storing the rated safe life of the lamp and verifies the validity of the values using a series of checksums and comparisons between the various values. The timer controller (106) also reads the series of locations storing the elapsed on time for the lamp and verifies the elapsed on time in a similar manner. If either the rated safe on time or the elapsed on time cannot be verified, the lamp is disabled. If both can be verified, and the lamp is enabled until the elapsed on time equals or exceeds the rated safe life.
