Abstract
A lighting selection system and method obtain individualized characteristic data for each of plural light emitting devices, determine a difference between a value of the characteristic data and a designated target value for each of the light emitting devices, and group the light emitting devices into different groups based on the differences between the values of the characteristic data and the designated target value. The differences of the light emitting devices in a common group of the groups are closer together than the differences of the light emitting devices in other groups of the groups. The system and method also may select at least one of the groups of the light emitting devices for inclusion in a light device.
Claims21
A method for forming a light device, the method comprising:
- measuring individualized characteristic data for each of plural light emitting devices with one or more sensors;
- receiving the individualized characteristic data for each of plural light emitting devices from the one or more sensors;
- determining a difference between a value of the characteristic data and a designated target value for each of the light emitting devices by one or more microprocessors;
- grouping the light emitting devices into different groups based on the determined differences between the values of the characteristic data and the designated target value by the one or more microprocessors, the differences of the light emitting devices in a common group of the different groups being closer to the designated target value than the differences of the light emitting devices in other groups of the different groups to the designated target value;
- generating a control signal by the one or more microprocessors to an automated system to select at least one of the different groups of the light emitting devices for inclusion in a light device;
- and
- including, based on the determined grouping of the light emitting devices into the different groups, the light emitting devices from the selected group in the light device.
A system for forming a light device, the system comprising:
- one or more sensors to measure individualized characteristic data for each of plural light emitting devices;
- and
- one or more microprocessors to receive the individualized characteristic data from the one or more sensors and to:
- determine a difference between a value of the characteristic data and a designated target value for each of the light emitting devices;
- determine different groups of the light emitting devices based on the determined differences between the values of the characteristic data and the designated target value, the differences of the light emitting devices in a common group of the different groups being closer to the designated target value than the differences of the light emitting devices in other groups of the different groups to the designated target value;
- generate a control signal to an automated system to select at least one of the different groups of the light emitting devices for inclusion in a light device and include, based on the determined different groups of the light emitting devices, the light emitting devices from the at least one selected group of the light emitting devices.
A method for forming a light device, the method comprising:
- measuring individualized characteristic data for each of plurality of light emitting diodes with one or more sensors, a value of the individualized characteristic data being chromaticity coordinates of light generated by each of the plurality of light emitting diodes;
- receiving the individualized characteristic data for each of the plurality of light emitting diodes from the one or more sensors;
- determining differences between the chromaticity coordinates of light generated by each of the plurality of light emitting diodes and a designated chromaticity coordinate of a designated target color for each of the light emitting diodes by one or more microprocessors;
- grouping, by the one or more microprocessors, the light emitting diodes into pairs based on the determined differences, each pair including the light emitting diodes having vectors extending from the chromaticity coordinates to the designated chromaticity coordinate that are closer in magnitude to each other than other light emitting diodes of the plurality of light emitting diodes but opposite in direction;
- generating a control signal by the one or more microprocessors to an automated system for selecting at least one of the pairs of the light emitting diodes for inclusion in a light device;
- and
- including, based on the determined grouping of the light emitting diodes into the pairs, the light emitting diodes from the selected group in the light device.
