  • Patent number: 11326747
    Abstract: Various examples concern techniques for opto-mechanically manipulating LED-based lighting systems. More specifically, various embodiments concern creating patterns of colored LEDs by determining the preferred color-specific density distribution and sequence(s) of LEDs. When creating the patterns, multiple considerations can be taken into account, including the power to be shared amongst the color channels when certain color models are generated by the linear array of LEDs, allocating an appropriate number of LEDs to each color channel to support the desired color spectrum, the sequencing of those LEDs along a string (e.g., as part of a linear array), etc. The appropriate number of LEDs for each color channel may be determined by first establishing the color model of the linear array within which the LEDs are interleaved.

  • Patent number: 11330684
    Abstract: A luminaire has a light-emitting diode (LED) light source, a light sensor, and a control system. The control system receives a Measure command measure the current intensity of the LED light source. The control system measures the intensity using the light sensor, stores current intensity data in non-volatile memory, obtains the LED light source's previous intensity, selects an indicator color representing how much the current intensity is reduced from the previous intensity, and causes the luminaire to emit a light beam having the indicator color. The control system also receives an Adjust command to reduce the LED light source to a total intensity reduction amount. The control system obtains the LED light source's current reduction amount, determines whether the total intensity reduction amount is more than the current reduction amount, and, if so, causes the LED light source to emit a reduced intensity light beam.

  • Patent number: 11324089
    Abstract: Introduced here are techniques for generating color mixing models that enable a tunable lamp to mix the right amount of light from various color channels in order to properly produce colors. More specifically, a lamp controller can be configured to drive multiple light-emitting diode (LED) arrays based on corresponding color mixing models. One or more color mixing models can be provisioned into the memory of an LED array prior to usage. Storing the color mixing model in the LED array enables the lamp controller to update the color mixing model based on which LED array it is serving (i.e., the lamp controller and the LED array need not be a permanently matched set). Additionally or alternatively, the lamp controller may be configured to communicate with a network-accessible computer server system to access a historical color mixing database that includes set(s) of previously-recorded spectral properties and corresponding color mixing models.
