Embodiment Construction

[0038] The features of the present invention will now be described in detail with reference to the drawings, in which like reference numerals designate like or corresponding parts.

[0039] Color output can be specified using the CIE color coordinate system. Other suitable color designation schemes may also be utilized. CIE, short for Commission Internationale de l'Eclairage, is the international standards development organization that first specified the way colors are quantified in standards written in 1931. The CIE color coordinate system is a recognized standard for measuring spectral distribution, and defines colors using x-coordinates, y-coordinates, and Y'coordinates. The CIE color coordinate system is a device-independent way of describing color, so it is also described as a general coordinate system for defining colors, and is shown graphically in Figure 2. Fig. 2 shows a CIE chromaticity diagram with a CIE color torque. The CIE color moment represents the x, y, an...

Abstract

A system including LED assemblies, which system can efficiently and consistently provide a desired color output. The system includes a network and a plurality of light emitting diode (LED) assemblies connected to the network. Each LED assembly includes a unique address. Further, a control unit is connected to the network and is configured to send light control signals to the LED assemblies individually. The light control signals include color information in a universal color coordinate system. The universal color coordinate system can be the CIE color coordinate system and the network can utilize an Ethernet communication protocol.

Description

technical field [0001] The present invention relates to an LED (Light Emitting Diode) assembly with a communication protocol for an LED light engine, and a method of manufacturing an LED assembly, and is particularly suitable for solving the problem of color difference between different LEDs within an LED assembly. Background technique [0002] Most of the traditional light sources are generally incandescent light sources or gas discharge light sources. Each light source has both advantages and disadvantages. Although cheap to manufacture, conventional incandescent lamps suffer from two drawbacks. First, most of the input energy to conventional lighting fixtures is wasted as heat or infrared (invisible) light; only a small amount of the input energy is converted into visible light. Second, incandescent lamps have a limited lifespan, and when they fail, the failure is catastrophic. Traditional fluorescent lamps have a long life, but their performance varies significantly o...
