Abstract

The invention provides an over-temperature protection circuit and method for an OLED lamp, and the OLED lamp. The over-temperature protection circuit comprises an OLED device and an OLED driving control panel. A thermosensitive element and a flexible circuit board are arranged in the OLED device; the thermosensitive element is arranged on the back surface of an OLED substrate of the OLED device and is used for detecting the temperature of the OLED device; the flexible circuit board is used for leading out the electric polarity of the OLED device and connecting the thermosensitive element with the OLED driving control board; the OLED driving control panel comprises a sampling circuit, a microprocessor and an OLED driving module; the sampling circuit collects the temperature detected by the thermosensitive element and sends the temperature to the microprocessor; the microprocessor generates a feedback signal according to the detected temperature and sends the feedback signal to the OLED driving module; the OLED driving module adjusts the temperature of the OLED device based on the feedback signal. According to the invention, over-temperature protection of the OLED lamp can be rapidly realized.

Description

Technical field[0001]The present invention relates to the field of automotive lamps, in particular to the technical field of automotive OLED lamps.Background technique[0002]The LED is used as the preferred light source of the car signal light, which has been widely used in the automotive signal of various functions. However, when the LED is used as a point light source, when the signal light is applied to a function of a function in the car, multiple LEDs generally need multiple LEDs to achieve a function, the luminescence effect of multiple LEDs, does not rely on a good optical reflex system and the mirror of the mirror. It is difficult to achieve good luminous uniformity. The organic light-emitting diode (OLED) product has two major advantages: one side of its own light, does not require any support for any light source system, and the thickness of the OLED illuminant is only 1.4 mm, and the future taillights can even be pasted like stickers. In the parking space, there is no need...
