Problems solved by technology

[0006] Because the light distribution in the space is not completely uniform, the difference in the viewing direction and viewing position will cause the eye illuminance value to change, resulting in large errors in the MRSE measurement results. great difficulty
In addition, the current illuminance testing instrument can only receive light radiation within 180° of the measurement point, and cannot obtain an accurate 36...

Embodiment Construction

[0027] figure 1 It is a schematic diagram of an embodiment of the present invention. It is composed of a light receiving module (01), a rhythm effect intensity analysis module (02), a spatial brightness evaluation module (03), an orientation positioning module (04), and a human-computer interaction module (05).

[0028] The light receiving module includes a light receiving module (01) including a cosine correction probe (101), a correction filter (102), a photoelectric conversion module (103), a spectrum probe (104), and a CCD matrix (105).

[0029] The illuminant emits light to form a lighting environment, and the light radiation irradiates the cosine correction probe (101). The cosine correction probe (101) adopts a white diffuse reflection material with an optical grade and high reflectivity at a field angle of 180 degrees, which can ensure that the probe not only receives direct light Optical radiation can also receive optical radiation irradiated to the probe from all d...

Abstract

The invention belongs to the technical field of optical radiation measurement, and particularly relates to a light environment test analyzer. The test analyzer comprises a light receiving module, a rhythm effect intensity analysis module, a spatial apparent brightness evaluation module, a directional positioning measurement module and a man-machine interaction module. Light radiation irradiates the light receiving module to obtain test light radiation, and the rhythm effect intensity analysis module calculates to obtain an equivalent visual melanin lux value index, and the spatial visual brightness evaluation module calculates to obtain a spatial visual brightness evaluation index; a test mode is selected through a control panel of the man-machine interaction module, a test state is started or quitted, test data is called or deleted, and a measurement result and the storage device can be transmitted through Bluetooth. Based on the photosensitive characteristic of human eye melanin protein, the rhythm effect intensity with direction or angle information can be directly measured, the accuracy of the measurement result is high, and the instrument is convenient and intuitive to operateand convenient to popularize.

Description

technical field [0001] The invention belongs to the technical field of light radiation measurement, and in particular relates to a light dose test analyzer. Background technique [0002] Light not only has visual effects, but also produces non-visual biological effects, such as affecting the human circadian rhythm system through non-visual channels. However, inappropriate artificial lighting and the work and lifestyle of modern society make the human body rhythm regulation mechanism dominated by natural sunlight fragile, and even cause a series of health problems such as sleep disorders and endocrine disorders. Therefore, the application of rhythmic healthy lighting indoors has a positive effect on the rhythmic health of people who have been in environments lacking natural light for a long time (such as high latitude areas, underground spaces, medical care spaces, etc.). [0003] Studies have shown (D.M.Berson, F.A.Dunn, M.Takao, Phototransduction by retinal ganglion cells ...
