Claim 0:
1. A lighting correction method, comprising steps sequentially executed as follows:
a correction relation obtaining step: providing a plurality of light emitting units, wherein each of the light emitting units emits light with at least a light emission peak wavelength and at least a wavelength range, and the light emitted by each of the light emitting unit has a light intensity;
and then, obtaining a mathematical relation or a relation table or graph having relationship of the light intensity or the relative intensity of each of the light emitting units and a junction temperature, and also obtaining a mathematical relation or a relation table or graph having relationship of a forward bias of each of the light emitting units and the junction temperature;
a forward bias measuring step: during a light emitting unit turned-on time interval, measuring the forward bias of the light emitting unit;
a ratio relation obtaining step: mapping the measured forward bias based on the obtained mathematical relation or the relation table or graph having relationship of the forward bias of each of the light emitting units and the junction temperature to calculate the junction temperature;
next, mapping the calculated junction temperature based on the obtained mathematical relation or the relation table or graph having relationship of the light intensity or the relative intensity of each of the light emitting units and a junction temperature to calculate the light intensity or the relative intensity; and next, comparing the calculated light intensity or the calculated relative intensity and a light intensity or a relative intensity corresponding to a specific junction temperature to obtain a ratio relation, wherein the light intensity or the relative intensity corresponding to the specific junction temperature is obtained from the mathematical relation or the relation table or graph having relationship of the light intensity or the relative intensity of each of the light emitting units and a junction temperature; and
a correction completing step: multiplying the light intensity of the wavelength range corresponding to the light emitting unit in the initial spectrum energy distribution curve by the ratio relation to achieve correction of the light intensity; or multiplying a measured spectrum signal of the wavelength range corresponding to the light emitting unit by the ratio relation to achieve correction of the spectrum signal.
