Embodiment Construction
[0038] The first embodiment of the present invention will be described in detail below. In this embodiment, the light illuminance detection and indication device does not distinguish application scenarios and light source types.
[0039] Such as figure 1 As shown, the light illuminance detection and indicating device is composed of a measurement unit 1 for measuring light illuminance, an indication and alarm unit 2 for providing relevant illuminance information, and a control unit 3 .
[0040] Such as figure 2 As shown, the actual required illuminance range is determined by the "lower limit". This data is stored in hardware or firmware inside the light illuminance detection and indication device.
[0041] Such as image 3 As shown, the indication information of the light illuminance detection and indication device includes an indication bar indicating the gradation of light illuminance and the illuminance range of each illuminance level, and an indicating arrow indicating...

The invention provides a simple, clear and reliable detection and indication device and a method for light illuminance. The detection and indication device and the method have functions such as light illuminance measurement, application scene setting, light source type identification, illuminance information indication and controlling. When the light illuminance is measured, the light illuminance is graded according to different feelings of human eyes, a relative relation between the current light illuminance level and the actually required illuminance range is indicated continuously, and different illuminance grades are adopted in different application scenes or the same application scene under different light source types. According to the detection and indication device and the method, light illuminance data obtained by measuring is converted to indication information and warning information of the illuminance grades, which can be easily understood by a user and suitable for a practical application situation and a using habit, the user can adjust the light illuminance, body postures or the application scenes very conveniently according to the indication information to ensure that the light illuminance is best suitable for a practical using condition of the user, eyesight is protected, and interference in normal study, work and life of the user is avoided.
Description
technical field [0001] The invention relates to a light illuminance detection and indication device and method, in particular to a light illuminance detection and indication device and method for protecting eyesight. Background technique [0002] In recent years, the myopia rate of Chinese students has been on the rise. An important reason is that the ambient light intensity is not suitable for studying, working and living with high eye intensity. Many times the light is too dark, and other times the light is too bright. Usually, there are two reasons for inappropriate light: one is that the light itself in the environment is not suitable (such as too bright or too dark), and the other is that the body posture (such as sitting or head posture) does not block the light correctly, making the original suitable When the light hits the target area, it is dimmed. [0003] However, whether the light is suitable or not can only be judged by professionals with the help of professi...
