Temperature adaptive control circuit for a light emitting diode, lighting and/or signaling apparatus
Patent number: 9854635Abstract: An embodiment of the present application provides a temperature adaptive control circuit for a light emitting diode and a lighting and/or signaling apparatus. The control circuit includes: a light emitting diode load circuit unit in which one or more light emitting diodes are connected; and a temperature adaptive circuit unit comprising a positive temperature coefficient thermistor and a negative temperature coefficient thermistor connected in series, wherein the temperature adaptive circuit unit is configured such that current flowing through the one or more light emitting diodes in the light emitting diode load circuit unit is a function of sum of resistance of the positive temperature coefficient thermistor and resistance of the negative temperature coefficient thermistor. It not only can compensate the variation of the luminescent intensity with the temperature in a desired working temperature for the LEDs, but also can achieve overheating protection for the LEDs to avoid damage thereof.Type: GrantFiled: December 5, 2016Date of Patent: December 26, 2017Assignee: VALEO LIGHTING HUBEI TECHNICAL CENTER CO.
