A gallium nitride ultraviolet detector

Abstract

The invention provides a novel gallium nitride ultraviolet detector. The novel gallium nitride ultraviolet detector is characterized by comprising a pipe cap and a base, wherein the pipe cap is matched with the base to form a sealed space; a window material is embedded in one end of the pipe cap; a PCB is arranged in the sealed space; the PCB is provided with a photoelectric diode and a pre-amplification circuit; the photoelectric diode detects an optical signal in the air outside the pipe cap, converts the optical signal into a current signal and transfers the current signal to the pre-amplification circuit; the pre-amplification circuit converts the received current signal into a voltage signal to be output; and the base is provided with an output pin connected with the output end of the pre-amplification circuit, a power supply pin connected with the power supply input end of the pre-amplification circuit, a grounding pin connected with the grounding end of the pre-amplification circuit, and a grounding base pin connected with an external grounding end. The invention, aiming to overcome the shortcomings in the prior art, provides the novel gallium nitride ultraviolet detector and a packaging method therefor, so as to reduce product size and setting of external circuits.

Description

technical field [0001] The invention belongs to the field of ultraviolet detection, and in particular relates to a gallium nitride ultraviolet detector and a packaging method thereof. Background technique [0002] The ultraviolet detectors in the prior art output more current, and an external amplifier circuit is needed to convert the weak current signal into a voltage signal and then transmit it to the processor. The external amplifier circuit is often easily mismatched with the internal detection circuit to cause errors. At the same time, the user also needs to configure the amplifier circuit by himself, which brings a lot of inconvenience to the use. Ordinary photodiodes are often used in general ultraviolet detectors, resulting in excessive product volume. Contents of the invention [0003] The purpose of the present invention is to provide a gallium nitride ultraviolet detector and its packaging method to reduce the volume of the product and the configuration of ext...
