20130154516 | SYSTEM AND METHOD FOR COLOR CREATION AND MATCHING - Systems and methods for controlling an output of a luminaire. The luminaire uses stored spectral information for light sources within the luminaire to determine a coordinate for each light source within a color space. A desired output color is also converted to a coordinate within the color space. The distance between the desired output color coordinate and each of the coordinates corresponding to the light sources is calculated to select initial control values for the light sources. The initial control values for each light source are individually modified by a step size value, the total output of the luminaire is calculated and converted to a coordinate within the color space, and the distance between the total luminaire output coordinate and the desired color coordinate is calculated. The control values for the light sources are iteratively modified until the luminaire output coordinate is within a threshold value of the desired color output. | 06-20-2013 |
20130082625 | COLORIZER AND METHOD OF OPERATING THE SAME - Systems and methods for controlling the output of a plurality of light sources. The system can include four or more light sources (e.g. light emitting diodes (“LEDs”)) and a controller. The light sources are included in, for example, a luminaire. The respective outputs of the plurality of light sources are controlled using a hue and purity (“HP”) control technique. The HP technique includes selecting a dominant hue (e.g., green, blue, red, etc.). The purity of the selected hue is then modified to include or remove wavelengths of light adjacent to the selected hue. For example, if the selected hue is green, gradually reducing the purity of the selected hue gradually increases the presence of cyan and amber in the output of the luminaire. As the purity is reduced further, additional wavelengths of light are included, but the output of the luminaire remains, in essence, green. | 04-04-2013 |

20120176063 | SYSTEMS AND METHODS FOR CONTROLLING AN OUTPUT OF A LIGHT FIXTURE - Systems and methods for controlling an output of a light fixture. A light fixture of one construction includes four or more light sources and is configured to produce an output that mimics the color temperature changes of an ideal black-body radiator based on one or more input parameters. The input parameters correspond to, for example, a desired target color and an intensity for the desired target color. A white point setting is determined based on the one or more input parameters and a relationship between the one or more input parameters and the color temperature of an ideal black-body radiator. A color temperature transform is selected based on the white point color temperature setting, and is used to determine a color coordinate corresponding to a modified target color. A set of light source output values corresponding to the modified target color are identified, and the light sources are driven to the identified output values. | 07-12-2012 |
20120176042 | SYSTEM AND METHOD FOR CONTROLLING THE SPECTRAL CONTENT OF AN OUTPUT OF A LIGHT FIXTURE - Systems and methods for controlling the spectral content of the output of a light fixture. The method of one embodiment includes driving the output of a light fixture to a target color and controlling the spectral content of the output of the light fixture. For example, a desired color is inputted using a color control methodology. A set of light source output intensity values that produce the desired color are identified, and then the light sources are driven to the identified output intensity values. A user is able to control the spectral content of the output of the light fixture by modifying the output intensity value of one or more of the light sources. After modifying the output intensity values, the color control and matching technique is used to identify a new set of output intensity values that maintain the previous target color but incorporate the changes in spectral content. | 07-12-2012 |
