The brightness of the space is closely related to the light stimulus obtained by the human eye, wherein the eye vertical illuminance is the main evaluation index.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings, for the purpose of making the objects, technical solutions and advantages of the present invention more apparent.
Referring to fig. 1, fig. 1 shows a specific structure of the indoor light environment assessment device of the present invention, which includes a detection module 2 and a user control terminal 1 connected to each other, and the user control terminal 1 includes a display screen module 11 and a micro-processing module 12 connected to each other. Specifically:
the detection module 2 is configured to obtain an optical parameter and send the optical parameter to the user control terminal 1. Wherein the optical parameters comprise eye vertical illuminance, reference glare value and lower glare value.
The display screen module 11 is used for inputting and/or setting spatial parameters and displaying optical parameters, spatial parameters and evaluation results. The spatial parameters are used for representing spatial data related to light rays in the indoor space, and specifically include a lamp installation height, a room height and a wall surface reflection coefficient (i.e. average reflectivity of a wall surface).
The micro-processing module 12 is used for calculating the illuminance of the indirect light eye according to the optical parameter and the space parameter, and generating an evaluation result of the brightness of the indoor space according to the illuminance of the indirect light eye.
The following describes the eye vertical illuminance, the reference glare value, the lower glare value, the lamp mounting height, the room height and the wall reflection coefficient, respectively:
the vertical illuminance (Vertical illuminance) refers to illuminance on a vertical plane, and the eye vertical illuminance (Corneal illuminance) refers to the intensity of illumination received by the eyes in the horizontal direction when the human body is in a normal sitting posture. When the vertical illuminance of eyes is measured, the measurement point is shown in fig. 2, the height of the sitting posture line of sight is 1.2m, the line of sight is horizontally oriented to the writing board (i.e. perpendicular to the writing board), then the measurement is performed by adopting the detection module 2, and finally the measured average value is taken. The eye vertical illuminance includes direct eye illuminance and indirect eye illuminance; the direct light eye illuminance refers to the part of the eye vertical illuminance where the light emitted by the lamp directly enters the human eye, namely the illuminance where the direct light enters the eye; the indirect light eye illuminance refers to the part of the eye vertical illuminance, in which light reflected by a table top, a wall and a ceiling light enters human eyes, namely the illuminance of the eye vertical illuminance, in which the reflected light enters the eyes; that is, eye vertical illuminance=direct eye illuminance+indirect eye illuminance.
The measuring point of the reference glare value is the midpoint of the indoor rear wall, the reference glare value is consistent with the requirements in the general indoor illumination standard, the detection module 2 needs to keep no interference of external light indoors during measurement, and the indoor lamp is fully opened at full power.
The lower illumination glare value refers to the glare value measured by the detection module 2 when all lamps in the indoor space are illuminated in the lower illumination mode, and the measurement point is consistent with the reference glare value, namely the lower illumination glare value refers to the glare value when the lamps are illuminated in the lower illumination mode.
The installation height of the lamp can be preset in the program of the micro-processing module 12 after being measured by the measuring device, or can be input into the micro-processing module 12 through the display screen module 11 (see fig. 3). Specifically, the data packet may be directly set into the micro-processing module 12 through the display screen module 11, or may be sent to the micro-processing module 12 after the setting of the display screen module 11 is completed.
The room height may be preset in the program of the micro-processing module 12 after being measured by the measuring device, or may be input to the micro-processing module 12 through the display screen module 11 (see fig. 3). Specifically, the data packet may be directly set into the micro-processing module 12 through the display screen module 11, or may be sent to the micro-processing module 12 after the setting of the display screen module 11 is completed.
The reflection coefficient of the wall surface can be obtained by striking the same light on the sample and the wall surface respectively in advance, calculating the reflectivity of the wall surface by measuring the reflectivity of the sample, and inputting the reflectivity to the micro-processing module 12 (see fig. 3) through the display screen module 11. Specifically, the data packet may be directly set into the micro-processing module 12 through the display screen module 11, or may be sent to the micro-processing module 12 after the setting of the display screen module 11 is completed.
In summary, optical parameters such as eye vertical illuminance, a reference glare value, a lower glare value and the like can be measured by the detection module 2 and then sent to the user control terminal 1; the space parameters such as the installation height of the lamp, the room height, the reflection coefficient of the wall surface and the like can be recorded or set through the display screen module 11 after being measured by other measuring equipment.
In operation, the microprocessor module 12 in the user control terminal 1 can calculate the illuminance of the indirect light eye according to the optical parameter and the spatial parameter, generate the evaluation result of the brightness of the indoor space according to the illuminance of the indirect light eye, and display the evaluation result through the display screen module 11. Therefore, the invention combines the calculation of the spatial brightness related index (namely the spatial parameter) with the measurement of the basic optical index (namely the optical parameter) aiming at the classroom illumination index group, performs the calculation of the spatial brightness related index while performing the optical detection, and visually displays the measurement and evaluation results of the related index.
Further, the micro-processing module 12 is further configured to calculate an EML value according to the optical parameter, and generate an evaluation result of the intensity of the rhythm effect according to the EML value. EML (Equivalent Melanopic Lux) and the like are used for quantifying the light measurement of the stimulus degree of the light source on the light response of the melanin, so that the intensity of the rhythm effect can be effectively evaluated by simultaneously calculating the EML value, and the evaluation result is displayed through the display screen module 11, so that the simultaneous presentation of a plurality of evaluation results is realized, and the user can conveniently grasp the space state in multiple aspects.
In addition, the detection module 2 and the user control terminal 1 may be connected by wireless or wired means. Preferably, wireless connection can be realized through a Bluetooth mode, wired connection can also be realized through USB, and the flexibility is strong. When the USB connection is adopted, the USB connection can be directly integrated through the two USB ports, and the USB connection can also be connected through a connecting wire.
As shown in fig. 4, the micro-processing module 12 includes a direct eye illuminance unit 121, an indirect eye illuminance unit 122, and a brightness evaluation unit 123, specifically:
the direct-light eye illuminance unit 121 is configured to calculate the direct-light eye illuminance according to the optical parameter and the spatial parameter.
The indirect eye illuminance unit 122 is used for calculating the indirect eye illuminance according to the optical parameter and the direct eye illuminance.
The brightness evaluation unit 123 is configured to generate an evaluation result of the brightness of the indoor space from the indirect eye illuminance.
The direct light eye illuminance refers to the illuminance of direct light entering the eyes in the eye vertical illuminance, and the indirect light eye illuminance refers to the portion of light reflected by the table top, the wall and the ceiling light entering the eyes in the eye vertical illuminance. That is, the spatial parameter is an influence factor of the illuminance of the eye of the indirect light, and the optical parameter is a result factor reflecting the illuminance of the eye of the indirect light, so the illuminance of the eye of the indirect light can be accurately calculated through the influence factor and the result factor.
Accordingly, since the eye vertical illuminance is the sum of the direct eye illuminance and the indirect eye illuminance, the eye vertical illuminance can be calculated according to the formula E cor,indirect ＝E cor -E cor,direct Calculating indirect photophthora illuminance E cor,indirect Wherein E is cor,direct For direct light eye illuminance, E cor Is the eye vertical illumination.
In addition, the indirect eye illuminance can effectively reflect the brightness of the indoor space, and in actual operation, the judgment can be performed according to the following table:
| indirect photopic illuminance (lx) | Evaluation results |
| 10 | Darkness |
| 30 | Dim light |
| 100 | Acceptable for |
| 300 | Bright |
| 1000 | Guo Liang |
As can be seen from the above table, when the indirect light eye illuminance is less than 100lx, the indoor space brightness is poor; when the indirect light eye illuminance is between 100 and 300lx, the brightness of the indoor space is better; when the indirect light eye illuminance is more than 300lx, the indoor space is too bright. Therefore, the brightness of the indoor space can be evaluated efficiently and low by calculating the illuminance of the indirect light eyes, and a basis is provided for adjusting the light of the indoor space.
For example, when the indoor space brightness is poor through the indirect light eye illuminance, the indoor space brightness can be improved through the mode of adding the lamp; for another example, when the indoor space brightness is judged to be too bright through indirect eye illuminance, the indoor space brightness can be reduced through a lamp reducing mode.
In the prior art, there is no definition of the brightness of the space, and the present invention creatively proposes a key index for evaluating the brightness of the indoor space, namely 'indirect eye illuminance'. The invention can obtain the corresponding indirect light eye illuminance value on the basis of not increasing the field test cost and the workload, and the scientificity, the convenience and the practicability of the index are all that the index has higher acceptability in the future, and simultaneously, the invention can provide important support for the improvement of the illumination quality of the indoor space in the future. Preferably, the present invention is applicable to classroom spaces.
As shown in fig. 5, the micro-processing module 12 further includes an EML calculation unit 124 and a rhythm evaluation unit 125, specifically:
the EML calculation unit 124 is configured to calculate an EML value according to an EML calculation formula.
The rhythm evaluation unit 125 is configured to generate an evaluation result of the rhythm effect intensity from the EML value.
The EML value may be calculated by means of a ratio conversion method. Since the conversion ratio of lx and EML is different for different light sources, the corresponding EML value can be calculated according to the conversion ratio of blacklight illumination (table one) after measuring the eye vertical illumination.
| CCT(K) | Light source | Ratio of |
| 2700 | LED | 0.45 |
| 3000 | Fluorescent lamp | 0.45 |
| 2800 | Filament lamp | 0.54 |
| 4000 | Fluorescent lamp | 0.58 |
| 4000 | LED | 0.76 |
| 5450 | CIE (equal energy) | 1 |
| 6500 | Fluorescent lamp | 1.02 |
| 6500 | Natural light | 1.1 |
| 7500 | Fluorescent lamp | 1.11 |
For example, if the illuminance of the incandescent lamp in the space is 200lx, the melanin illuminance at this time is 200×0.54=108 EML.
Therefore, the EML value can be calculated through the optical parameter, so that the evaluation result of the rhythm effect intensity is conveniently generated.
As shown in fig. 6, the direct-light eye illuminance unit 121 includes a first computing subunit 1211 and a second computing subunit 1212.
A first calculation subunit 1211 is configured to calculate a spatial reference parameter according to the spatial parameter. It should be noted that different indoor spaces have different spatial parameters, and different spatial parameters will cause different reflection states of the indoor spaces. Therefore, by targeted processing of the spatial parameters, spatial reference parameters can be derived, wherein the spatial reference parameters are used to represent the relationship between the reference glare value duty cycle (i.e., the duty cycle of the reference glare value in the lower glare value) and the direct-light eye illuminance duty cycle (i.e., the duty cycle of the direct-light eye illuminance in the eye vertical illuminance), and can be calculated from the luminaire mounting height and the wall reflection coefficient.
Specifically, the first computing sub-unit 1211 calculates the first value according to the formula a=k 1 H light /H room +k 2 ·ρ+k 3 -b, calculating the spatial reference parameter a.
Wherein:
k 1 ，k 2 ，k 3 is constant and can be preset in the program of the micro-processing module, generally k 1 ，k 2 ，k 3 The values of (2) are between-10 and 10, but not limited thereto, and can be set according to practical situations, preferably k 1 ,k 2 ,k 3 The value of (2) can be between-5 and 5 so as to further improve the accuracy;
H light the installation height of the lamp can be preset in a program of the micro-processing module or can be input into the micro-processing module through the display screen module; concrete embodimentsThe data packet can be directly arranged in the micro-processing module through the display screen module, or can be sent to the micro-processing module after being arranged through the display screen module.
H room The height of the room can be preset in a program of the micro-processing module or can be input into the micro-processing module through the display screen module; specifically, the data packet can be directly set into the micro-processing module through the display screen module, or can be sent to the micro-processing module after being set through the display screen module.
ρ is the wall reflection coefficient and can be input to the micro-processing module through the display screen module; specifically, the data packet can be directly set into the micro-processing module through the display screen module, or can be sent to the micro-processing module after being set through the display screen module.
b is an intercept, and is used for representing a correction value between the reference glare value duty ratio and the direct-light eye illuminance duty ratio, and can be set according to practical situations, and accordingly, a mapping relation table of ρ and b is preset in a program of the micro-processing module, and the mapping relation table is used for extracting a value of b related to the value of ρ.
The value of the intercept is related to the wall reflection coefficient. Specifically, the intercept acquisition method comprises the following steps: searching a preset mapping relation according to the wall reflection coefficient to obtain a corresponding intercept, wherein the preset mapping relation is used for recording the corresponding relation between the wall reflection coefficient and the intercept. The preset mapping relationship may be recorded in a table or graphic manner, for example, when the table manner is adopted, the preset table is as follows:
| wall reflection coefficient | Intercept of (intercept of) |
| 0.6 | -0.03 |
| 0.7 | -0.06 |
| 0.8 | -0.08 |
| 0.9 | -0.10 |
The larger the wall reflection coefficient is, the smaller the intercept is, as can be seen from the preset mapping relation.
The second calculating subunit 1212 is configured to calculate the direct-light eye illuminance according to the spatial parameter, the spatial reference parameter and the optical parameter. The direct-light eye illuminance refers to the illuminance of the eye in which the light emitted by the lamp directly enters the eye, i.e., the direct light enters the eye in the eye vertical illuminance. Therefore, the direct photopic eye illuminance can be separated from the eye vertical illuminance by the information of the spatial parameter, the spatial reference parameter, the optical parameter and the like.
Specifically, the second computing subunit 1212 is according to formula E cor,direct ＝(a·UGR/UGR max +b)E cor Calculating direct photopic eye illuminance E cor,direct 。
Wherein:
E cor the eye vertical illuminance can be measured by the detection module and then sent to the user control terminal;
UGR is a reference glare value, and can be measured by a detection module and then sent to a user control terminal;
UGR max the lower illumination glare value can be measured by a detection module and then sent to a user control terminal;
a is a space reference parameter;
b is the intercept.
Therefore, the invention can obtain the corresponding direct light eye illuminance value on the basis of not increasing the field test cost and workload, thereby obtaining the indirect light eye illuminance value, outputting the corresponding evaluation result and providing important support for improving the illumination quality of the indoor space in the future.
While the foregoing is directed to the preferred embodiments of the present invention, it will be appreciated by those skilled in the art that changes and modifications may be made without departing from the principles of the invention, such changes and modifications are also intended to be within the scope of the invention.
