Abstract

The invention is applicable to the field of an illumination circuit, and particularly relates to a light fixture temperature self-adaptive protection circuit and a light fixture. In the embodiment of the invention, the light fixture temperature self-adaptive protection circuit is connected with a temperature detection circuit and a light fixture output power control circuit respectively; through receiving the signals sent by the temperature detection circuit, the light fixture temperature self-adaptive protection circuit determines whether the temperature of the housing of the light mixture is too high or too low and controls the light fixture output power control circuit so as to enable the light fixture output power control circuit to control the output power of the light mixture to perform self-adaptive adjustment according to the temperature of the housing.

Description

technical field [0001] The invention belongs to the field of lighting circuits, and in particular relates to a lamp temperature adaptive protection circuit and a lamp. Background technique [0002] As a conventional electrical product, lamps are widely used in people's daily life. [0003] Generally, after the working time of the lamp is too long, the temperature of the shell will rise, and the temperature of the shell of the lamp is related to the output power of the lamp. The greater the output power, the higher the temperature of the shell of the lamp. [0004] In general, the output power of the lamp is constant, but in some applications, due to the long working time of the lamp, the temperature of the shell will be too high, which will cause safety hazards, which requires that the output power of the lamp can be adjusted with the temperature of the shell. Adaptive adjustment, but at present there is no output power of a lamp that can be adaptively adjusted with tempera...
