Led array module

An apparatus, comprising:

• an array of light emitting diodes (LEDs),
• the LEDs configured to produce primary light having a primary wavelength,
• the LEDs including a phosphor configured to absorb at least a portion of primary light that strikes the phosphor and, in response to said absorption, emit secondary light having a wavelength longer than the primary wavelength,
• the LEDs further configured to emit emitted light that is a combination of the primary light and the secondary light,
• the emitted light having a correlated color temperature determined by a ratio of primary light to secondary light,
• the array of LEDs configured such that at least some of the LEDs direct a portion of the produced light to adjacent LEDs as crosstalk light,
• the array of LEDs configured to control a correlated color temperature of the LEDs by controlling a level of the primary light produced by each LED based at least in part on a level of the crosstalk light received at the LED.

A method, comprising:

• producing, with an array of light emitting diodes (LEDs), primary light having a primary wavelength;
• absorbing, with a phosphor included with the array, at least a portion of primary light that strikes the phosphor;
• emitting, with the phosphor, in response to said absorption, secondary light having a wavelength longer than the primary wavelength;
• emitting, with the LEDs in the array, emitted light that is a combination of the primary light and the secondary light, the emitted light having a correlated color temperature determined by a ratio of primary light to secondary light;
• directing a portion of the emitted light to adjacent LEDs in the array as crosstalk light;
• and
• controlling a correlated color temperature of the LEDs by controlling a level of the primary light produced by each LED based at least in part on a level of the crosstalk light received at the LED.

An apparatus, comprising:

• a rectilinear array of light emitting diodes (LEDs) that are configured to produce light and direct a portion of the produced light to adjacent LEDs in the array as crosstalk light,
• the array having a central area and a border area surrounding the central area,
• the LEDs in the array being distributed between a central group of LEDs positioned in the central area and a border group of LEDs positioned in the border area,
• each LED in the central group being surrounded by four directly adjacent LEDs and four diagonally adjacent LEDs in the array of LEDs,
• each LED in the border group being surrounded by fewer than four directly adjacent LEDs or fewer than four diagonally adjacent LEDs in the array of LEDs,
• the array of LEDs configured to control a correlated color temperature of the LEDs by setting a level of primary light produced by the central group of LEDs to a first level and setting a level of primary light produced by the border group of LEDs to a second level greater than the first level.
