Embodiment Construction

[0010] As shown in Figure 1, a kind of ultraviolet detector comprises optical filter, ultraviolet sensor 1, signal amplifying circuit 2, photosensitive diode 3, single-chip microcomputer 4 and LED display 5, and optical filter is connected with ultraviolet sensor 1, and photosensitive diode 3 is connected with The ultraviolet sensor 1 is connected in parallel with the signal amplifying circuit 2 in series, and the signal amplified by the signal amplifying circuit 2 is processed by the single-chip microcomputer 4 and then sent to the LED display 5 .

[0011] Detection principle: the lighting light passes through the filter lens to filter out light sources other than ultraviolet light, and only ultraviolet light source (100-400nm) shines on the ultraviolet sensor 1. When there is an ultraviolet light source, the two ends of the silicon photocell in the ultraviolet sensor 1 will generate current.

[0012] The ultraviolet light source is super strong, the greater the current at bo...

Abstract

An ultraviolet ray detector comprises an optical filter, an ultraviolet ray sensor, a signal amplification circuit, a photosensitive diode, a singlechip and an LED display. The optical filter is connected with the ultraviolet ray sensor; the photosensitive diode is connected with the ultraviolet ray sensor in parallel and connected with the signal amplification circuit in series; and a signal amplified through the signal amplification circuit and processed through the singlechip is output to the LED display. With the above structure, the optical filter filters out light source except the ultraviolet ray, an ultraviolet signal is detected by the ultraviolet ray sensor, amplified through the signal amplification circuit and sent to the singlechip for analysis and processing, and processed data is transmitted to the LED display for display, therefore, the value of the ultraviolet ray intensity can be seen, thereby achieving the purpose of conveniently and quickly detecting the intensity of the ultraviolet radiation of indoor lighting lamps.

Description

technical field [0001] The invention relates to a detector, in particular to an ultraviolet detector. Background technique [0002] The data of the intensity of ultraviolet light measured by existing instruments for measuring ultraviolet rays is not accurate, and there is no instrument that can detect ultraviolet rays of lighting fixtures indoors. Contents of the invention [0003] The purpose of the present invention is to provide a kind of ultraviolet detector that can carry out ultraviolet safety measurement to indoor lighting lamps and lanterns, [0004] The object of the present invention is achieved like this: a kind of ultraviolet detector, comprises optical filter, ultraviolet sensor, signal amplifying circuit, photosensitive diode, single-chip microcomputer and LED display, optical filter is connected with ultraviolet sensor, after photosensitive diode and ultraviolet sensor are connected in parallel It is connected in series with the signal amplifying circuit, a...
