Lamp

Abstract

The invention relates to a lamp which comprises a lamp shell, a light source positioned in the lamp shell, a cover body, a temperature measurement and control assembly and a pipeline. When working, the light source generates heat in the lamp shell; the cover body covers the lamp shell and an accommodating cavity is formed; the temperature measurement and control assembly is arranged in the accommodating cavity and comprises a temperature difference sensing needle and a control valve; the temperature difference sensing needle senses temperature variation in the lamp shell and generates a current according to the temperature variation; the control valve is arranged on the pipeline and is connected with the temperature difference sensing needle; the control valve is opened according to the current input by the temperature difference sensing needle and controls conduction of a piping in the pipeline in real time so as to lead out heat in the lamp shell. The lamp effectively solves the problems of low heat dissipation efficiency when heat is conducted by the shell and nonuniform lamp temperature of an existing lamp; the service life of the lamp is prolonged; moreover, the requirements of the specific working environment are met.

Description

technical field [0001] The invention relates to the field of lighting, in particular to a lamp. Background technique [0002] Fluorescent lamps, halogen lamps, floodlights, and LED lamps have become indispensable lighting fixtures in people's lives and work. These lamps are increasingly used in various aspects of people's lives and work, such as advertising, signs, lighting , interior decoration and other applications. When in use, these lamps emit different light after being powered on, and generate a lot of heat during the working process, most of which can only be conducted and dissipated through the shell of the lamp. [0003] However, such a heat dissipation method often has low efficiency, which will cause uneven temperatures inside the lamp and on the surface of the housing, reducing the service life of the lamp. Moreover, when these lamps work, they are higher than the temperature of the surrounding environment, and the heat emitted by them will cause the temperatu...

AI Technical Summary

Problems solved by technology

[0003] However, such a heat dissipation method is often inefficient, which will lead to uneven temperature inside the lamp and the surface of the shell, reducing the service life of the lamp

Moreover, when these lamps work, they are higher than the temperature of the surrounding environment, and the heat emitted by them will cause the temperature of the surrounding environment to rise, which is difficult to meet the needs of specific working environments, such as hospitals, computer rooms, storage rooms, laboratories, pharmaceutical workshops, etc. Where a constant temperature or temperature range is required
