Suppose you have an LED that emits a spectrum of colours such that the resultant colour emitted is white. Will changing the temperature if the LED itself change the composition of the light's colour spectrum, hence changing its resultant colour?
My immediate answer to this is no but after a bit of research, I came accross this graph:
The website states that:
Figure 9 shows the light output of several LEDs as a function of junction temperature. The temperature dependence is much less for InGaN LEDs (e.g., blue, green, white) than for AlGaInP LEDs (e.g., red and yellow).
As the graph clearly shows, the relative light outputs of the red, white and blue light changes at different rates as temperatures increase. This shows how the intensity of the light overall changes with the temperature of the LED system. However, does this mean that the colour composition of the emitted light changes with temperature as well?
