摘要： A light emitting diode (LED) module includes a plurality of LED strings and a module controller. The LED strings are connected to each other in parallel, and each of the LED strings emits light that has a different color temperature from that of the other LED strings. The module controller is configured to detect an input voltage applied to the plurality of LED strings, adjust a color temperature of the light emitted by the plurality of LED strings by adjusting a ratio of current respectively supplied to each of the plurality of LED strings based on the input voltage, and reduce a change in a luminous flux of the light emitted by the plurality of LED strings regardless of the color temperature of the light emitted by the plurality of LED strings.

摘要： A light emitting module is configured to provide substantially uniform lighting using a plurality of lighting sources. The light emitting module includes a diffusion plate disposed at a set distance from the light emitting module. A light source substrate has a substantially quadrilateral outer perimeter with at least one gap formed therein, and a plurality of light sources are disposed on the light source substrate according to a repeated quadrilateral pattern. A distance between adjacent light sources in the repeated quadrilateral pattern is selected based on the set distance h from the diffusion plate to the light emitting module, and on a greater of two diagonal distances x, y of the quadrilateral pattern. The diffusion plate diffuses light emitted by the light sources to provide substantially uniform light. Various other aspects of the light emitting module are additionally described.
