Abstract

The invention discloses a photometry alarm circuit for eyesight protection. The photometry alarm circuit can test the light of a current environment by using a flash dedicated chip KD-01x in cooperation with a photoresistor RT. If the light meets a condition, a yellow light-emitting diode is lighted. When the light is dark, a red diode is controlled to blink to give an alarm so as to remind a user to switch on a lamp, thereby protecting eyesight. The photometry alarm circuit is safe and reliable, low in power consumption, simple in circuit, and low in cost, and has good application prospect.

Description

technical field [0001] The invention relates to a photometry alarm circuit for eyesight protection, which belongs to the technical field of electronic products. Background technique [0002] At present, when people are reading or working, sometimes the light is not good, and when it is dark, they need to turn on the lights. However, because people are very involved in reading or working, they often cannot turn on the lights in time, resulting in people's vision loss. , It is very harmful, how to remind people to turn on the light in time when the light is not good is a problem that needs to be solved in current life. Contents of the invention [0003] The purpose of the present invention is to overcome the problem that people often cannot turn on the illuminating lamp in time when the light is not good, which causes people's eyesight to decline. The photometric alarm circuit for eyesight protection of the present invention can test the light in the current environment thr...
