A Device for Compensating the Effect of Temperature Variation on the Brightness of LEDs
A device for compensating the effect of temperature variation on the brightness of LEDs has been developed by us. We invite interested parties to contact us for exploring the possibilities of licensing this technology.
Sector: Electrical & Electronics
Area of Application: •Camera calibration •Color printer application •Automobile applications e.g traffic light, signal light etc.. •LED displays in different instruments
Keywords: SAC, TTID, LED, Camera, Automobile Lights
Advantages: •The LED driver circuit will provide bias to the LEDs to provide temperature compensated brightness without using any temperature sensors. •No temperature sensor is required, since properties of the diodes themselves are used to achieve the temperature compensation performance. •The temperature controlled bias voltage/current generated according to the junction temperature of the LEDs themselves, thus any temperature gradient will not affect the temperature compensation. •Temperature changes induced by power dissipated within the diodes are also compensated. No trial and error method is involved to optimize the circuit performance.
