The present invention both can be the decimal system, also can be the M scale coding, and M is 〉=2 positive integer.Luminescent device is distinguished digitally coded figure place for sending two or more heterogeneous light luminescent devices with glow color at this moment.First kind of color corresponding to first, glimmer N1 time continuously, second kind of color corresponding to second, glimmer N2 time continuously, the third color corresponding to the 3rd, glimmer N3 time continuously, the digital coding value then is N1+N2 * M+N3 * M * M, wherein N1, N2, N3 be positive integer and＜M.T change-over time between the different colours is the fall time, t 〉=0.The rest may be inferred for more multiple light color.

Luminescent device can adopt light-emitting diode.The color that light-emitting diode can send is abundant, and is beautiful in colour, cheap, and dependable performance is highly suitable for household electrical appliance or conventional equipment or high accuracy point complex device.Luminescent device also can adopt bulb or fluorescent tube.Bulb or fluorescent tube are cheap, are particularly useful for household electrical appliance or conventional equipment.

Luminescent device can also adopt laser generator.Though the laser generator price is more expensive, energy is high and concentrated, and the reliability height is particularly useful for complex device.

The invention provides a kind of simple in structure, accurately and reliably, with low cost, be easy in household electrical appliance or conventional equipment, apply, good effective in high-grade, precision and advanced complex device, both can express information about power, also can express the digital coding method with optical flare number of times expressing information of non electrical quantity information.
