Mobile phone blue light testing method

Abstract

The invention discloses a method for testing blue light of a mobile phone. According to the invention, the average brightness in the effective view field angle center f is firstly tested, the opticalenergy received by the diaphragm aperture D limit value is limited by the aperture F, and finally the optical energy is received by the integrating sphere. The testing system can meet the following requirements: (1) a light source is imaged on a detector; (2) a circular view field diaphragm is arranged, and an angle range with the average view field as the center f is formed; (3) a circular entrance pupil is provided, and the circular entrance pupil is the same as an average diaphragm in irradiance measurement; for a small angle, the relation between the diameter of a detector in the imaging system and the focal length is d = aH, and therefore a measuring system schematic diagram of blue light is obtained; then, the blue light hazard characteristic of a certain light source can be measuredand evaluated by taking the light source as a core; by combining a professional detection instrument for blue light harm, the purpose of evaluating the blue light harm condition at any position is achieved, so that the test effect is more accurate, and the operation of people is simpler and more convenient.

Description

technical field [0001] The invention belongs to the technical field of blue light testing, in particular to a testing method for mobile phone blue light. Background technique [0002] As more and more people realize that being addicted to electronic products for a long time can cause various uncomfortable symptoms in the eyes, they begin to pay attention to the cause of eye damage-the concept of blue light, the concept of "blue light" that hurts the eyes, refers to It is a light that can cause damage to the eyes. In sunlight, there is blue light, and in the screen of a mobile phone, blue light can also be produced. But the wavelength range of blue light in the sun and the screen of the mobile phone are not the same, they have some differences; but if we stare at the bright white computer mobile phone screen for four or five hours instead of seven or eight hours, our eyes will start to get tired , soreness or something. So we need anti-blue light, which is aimed at the blu...

Problems solved by technology

[0003] However, the common test method is not accurate enough, and at the same time, it cannot fix the mobile phone, which makes the mobile phone shake easily during the test process, resulting in inaccurate test results.
