Abstract

The invention provides an over-temperature protection device, a method and electrical equipment. The over-temperature protection device is used for performing over-temperature protection of electrical equipment and comprises a transparent window unit and a photo-switch; the transparent window unit is made of a transparent material and arranged on the shell of the electrical equipment; a thermochromic thin film is coated on the internal surface of the transparent window unit; the photo-switch is arranged inside the shell of the electrical equipment; ambient light shines on the photo-switch via the transparent window unit; and the photo-switch is used for controlling the shutdown of the electrical equipment when the spectrum of the received light is within the preset spectral range. According to the over-temperature protection device, the method and the electrical equipment, the over-temperature protection effect is realized; the over-temperature pre-warning is earlier and more intuitive; and the realization manner is simple and the own load of the electrical equipment is reduced.

Description

technical field [0001] The invention relates to the technical field of overheating protection, in particular to an overheating protection device, method and electrical equipment. Background technique [0002] While the current TV is developing towards high-end intelligence such as large size and high resolution, the power consumption and heat dissipation of the internal circuit IC (integrated chip) are also increasing. When the temperature exceeds 120 degrees, it will affect its working characteristics. TV Both quality and lifespan will be threatened, and an over-temperature protection system needs to be built in. [0003] At present, the commonly used overheating protection devices basically start from the pure circuit point of view, which will have a large burden on the electrical equipment itself, especially the circuit structure of small electrical appliances, and there is no more intuitive overheating warning visual prompt before the overheating shutdown .
