Claim 21:
22. An LED lighting device configured for providing light suitable for a commercial image recording, the LED lighting device comprising:
(a) a support structure;
(b) a housing for the support structure;
(c) an array of LED emitting devices mounted on the support structure, wherein the array of LED emitting devices is configured to emit four different colors of light and comprises: a first set of LED emitting elements configured to emit light of a first color; a second set of LED emitting elements configured to emit light of a second color; a third set of LED emitting elements configured to emit light of a third color; and a fourth set of LED emitting elements configured to emit a broad-spectrum white light within a predetermined Kelvin temperature range;
(d) a controller coupled to the array of LED emitting devices and configured to receive commands for operating select ones of the LED emitting devices with varying amounts of power to produce light consisting of varying amounts of the four different colors provided by the first, second, third and fourth sets of LED emitting elements to produce many different colors outputted from the lighting device, and further comprising an LED driver, the LED driver configured to selectively provide electrical power to the array of LED emitting devices;
(e) wherein the housing has a linear form factor substantially that of a fluorescent tube having an axial direction and a narrow diameter in relation to the length, and further comprising an electrical input connection for receiving input power, wherein the input connection is in electrical communication with the LED driver;
(f) wherein the housing has opposite ends and the support structure is in a form of an elongated and narrow surface extending in the axial direction and the housing having a top side and a bottom side which each extend in the axial direction, and wherein the LEDs are configured to emit light from the top side of the housing along a length of the housing between the opposite ends, and the top side of the housing has a diffusion cover extending the axial length of the support between the ends;
(g) wherein the housing has a linear form factor substantially that of a fluorescent tube of one of a T12 and T8 form;
(h) wherein the lighting device is configured to receive an input wattage, the electrical input connection is configured to receive AC input power and has at least one of an inverter and a power supply in the housing and the LED driver is disposed within the housing and is configured to provide up to the input wattage to the LEDs;
(i) wherein the LED controller is configured to control the LED driver to selectively provide an output of tungsten white light with substantially no daylight white and of daylight white light with substantially no tungsten white light from among the many different colors outputted from the lighting device, and wherein each of the tungsten white light output is suitable for the commercial image recording industry and wherein the daylight white light output is suitable for the commercial image recording industry;
(j) wherein the tungsten white light output with substantially no daylight white from the LED lighting device is suitable for the commercial image recording industry when the tungsten white light outputted from the LED lighting device: (i) is at least 1000 lumens; (ii) is broad-spectrum white light having a color deviation corresponding to less than five points of green and less than five points of magenta (5M, 5G) of color compensation (CC), and (iii) has a color rendering index of light greater than 90; and
(l) wherein the daylight white light output with substantially no tungsten white from the LED lighting device is suitable for the commercial image recording industry when the daylight white light outputted from the LED lighting device: (i) is at least 1000 lumens; (ii) is broad-spectrum white light having a color deviation corresponding to less than five points of green and less than five points of magenta (5M, 5G) of color compensation (CC), and (iii) has a color rendering index of light greater than 90.
