Description

Technical Field

[0001] This application belongs to the field of photodetector technology, specifically a photodetector that is easy to fix. Background Technology

[0002] A photodetector is a device that converts light signals into electrical signals. Its working principle is based on the photoelectric effect. When the energy of the irradiated photon is equal to or greater than the bandgap of the semiconductor, the photon can excite electrons in the valence band to the conduction band, thereby generating conductive electron-hole pairs. Thermal detectors are based on the fact that the temperature of a material increases after absorbing light radiation energy, thereby changing its electrical properties. Common photodetectors include photomultiplier tubes, photoresistors, photodiodes, phototransistors, and photovoltaic cells. Photodetectors have advantages such as high sensitivity, fast response, and low noise, and are widely used in optical communication, instrumentation, security, environmental monitoring and other fields.

[0003] For example, utility model patent CN222013150U discloses a photodetector with easy heat dissipation, which relates to the field of photodetectors. It includes a mounting body, a detection component fixedly mounted at the bottom of the mounting body, a protective component provided at the top of the mounting body, and a protective shell including a protective shell fixedly mounted on the top of the mounting body. A ventilation component is fixedly mounted on one side of the protective shell, and a hoisting component is provided at the top of the protective shell. This application uses a fan to deliver air to the heat dissipation fins for cooling, and the hot air during detector heat dissipation is discharged through the vent grille, which can effectively improve the heat dissipation efficiency of the circuit board and field-effect transistor.

[0004] However, it was discovered during actual use that the detection component of the device is installed inside the main body of the installation and fixed by the hoisting component, which enables the detection component to effectively detect the surrounding environment.

[0005] However, when it is necessary to maintain or inspect the detection components inside the installation body, the bolts of the hoisting components must be removed before the installation body can be further disassembled for maintenance. After maintenance is completed, the bolts must be reinstalled for fixation. This method makes the disassembly process of the installation body cumbersome, affecting maintenance efficiency and the convenience of quick installation. Therefore, a photoelectric detector that is easy to fix is ​​provided. Utility Model Content
