Description

Technical Field

[0001] The invention relates to the field of architectural light environment design, and in particular to a physiological equivalent illumination measurement method and device. Background Art

[0002] The building light environment is the basis and necessary condition for people to engage in work and entertainment activities. A healthy light environment is an important part of a healthy building. Light has a huge impact on people's physiology and psychology. It is an important factor affecting the human physiological rhythm and will directly affect human health. Studies have shown that the light environment not only affects people's visual and psychological comfort, but also causes non-visual effects, thereby affecting the human physiological rhythm.

[0003] With the development of healthy buildings, relevant evaluation standards have put forward new requirements for indoor light environment evaluation indicators. The "Healthy Building Evaluation Standard" (T / ASC02-2016) puts forward requirements such as color transmittance index, lighting uniformity, biosafety, natural light dynamic lighting illumination, physiological equivalent illumination, lighting control system, lighting control and shading device control. Among them, the indicator of physiological equivalent illumination is quoted from the theory of the American WELL Healthy Building Standard. Light of different intensities and spectra has different effects on human physiological rhythms. Physiological equivalent illumination represents the ability of the lighting environment to stimulate human melatonin. The higher the value, the higher the ability of lighting to stimulate melatonin. In order to ensure a comfortable and efficient working environment, the physiological equivalent illumination in the main sight direction should be appropriately increased. For residential buildings, in order to ensure a good rest environment, the physiological equivalent illumination should be reasonably reduced at night while meeting the visual illumination; for public buildings, in order to ensure a comfortable and efficient working environment, the physiological equivalent illumination in the sight direction at eye height should be appropriately increased. Referring to the provisions of the International Commission on Illumination CIE, physiological equivalent illumination The illuminance value when using CIE standard light source D65 to produce the same melanin equivalent lighting.

[0004] At present, the technical research on building light environment, especially the calculation of physiological equivalent illuminance, has the following problems:

[0005] 1) Imperfect calculation method: Currently, the only calculation basis available for reference is the simple calculation method of equivalent melanopic lux (EML) given in the American WELL evaluation standard. This method only gives the ratios under several typical color temperatures. There is no explanation on the color temperature of natural light under different design conditions, how to calculate the ratio, how to determine the visual illumination under natural lighting, and how to determine the ratio of artificial lighting under different color temperatures. This brings great difficulties to designers in carrying out interior lighting design;

[0006] 2) Design is difficult: Healthy building light environment involves cross-disciplinary design, involving natural lighting (architecture) and artificial lighting (electrical and lighting). How to design to meet the relevant index requirements and how to reasonably use natural lighting and effectively combine artificial lighting are difficult to design;

[0007] 3) Lack of testing methods: How to test and evaluate in engineering projects, especially how to calculate indoor physiological equivalent illuminance through sensor testing of illuminance, color temperature and other indicators, has not yet formed a relatively complete testing method.

[0044] Please refer to Figure 1 This embodiment provides a physiological equivalent illuminance measurement method, including:

[0045] S1. Provide various common lamps suitable for indoor light environment and build a light wave characteristic database, wherein the light wave characteristic data of various common lamps are pre-stored in the light wave characteristic database;

[0046] S2. Performing field measurement on the indoor light environment to be detected to obtain measured data, wherein the measured data includes absolute spectral power distribution and / or relative spectral power distribution and vertical illuminance in the direction of sight at eye height of the working area;

[0047] S3. Calculate the physiological equivalent illumination of the indoor light environment based on the light wave characteristic data of the lamps used in the indoor light environment and the corresponding measured data.

[0048] The present invention can quickly calculate the physiological equivalent illumination of the indoor light environment by using known light wave characteristic data and actual measured data obtained by field measurement, thus solving the problem that the current physiological equivalent illumination measurement method is imperfect.

[0049] Specifically, S1 is first executed to provide various commonly used lamps suitable for indoor light environments and construct a light wave feature database, in which light wave feature data of various commonly used lamps are pre-stored. In this embodiment, the light wave feature data can generally be directly provided by the lamp manufacturer and is known data, which generally includes the spectral luminous efficiency corresponding to different wavelengths emitted by the lamp when lighting and the melanopsin protein efficiency of the corresponding wavelength.

[0050] Then, S2 is executed to perform field measurement of the indoor light environment to be detected to obtain measured data, wherein the measured data includes the absolute spectral power distribution and / or the relative spectral power distribution and the vertical illuminance in the direction of the eye height of the working area. It should be noted that the and / or here should include the following three situations:

[0051] 1) The measured data only includes the absolute spectral power distribution;

[0052] 2) The measured data only include the relative spectral power distribution and the vertical illuminance in the direction of sight at the eye height of the working area;

[0053] 3) The measured data also includes absolute spectral power distribution, relative spectral power distribution and vertical illuminance in the direction of sight at eye height in the working area.

[0054] The different measured data obtained here can be used to calculate the physiological equivalent illuminance of the indoor light environment using different calculation methods, which will be introduced in detail later.

[0055] Preferably, the absolute spectral power distribution and the relative spectral power distribution can be measured by a spectrometer, and the vertical illuminance in the direction of the eye height of the working area can be measured by an illuminometer. The spectrometer can measure the absolute spectral power distribution and the relative spectral power distribution, but in practical applications, the measurement of the absolute spectral power distribution usually requires accurate radiometric measurement equipment, and is usually used for scientific research and precise light source analysis, while the relative spectral power distribution provides a more convenient measurement method, allowing the use of arbitrary units to express power, which is more common in practical applications, so the relative spectral power distribution is generally measured.

[0056] Finally, S3 is executed to calculate the physiological equivalent illumination of the indoor light environment based on the light wave characteristic data of the lamps used in the indoor light environment and the corresponding measured data. In this embodiment, based on the light wave characteristic data of the lamps used in the indoor light environment and the corresponding measured data, there are the following three modes to calculate the physiological equivalent illumination of the indoor light environment.

[0057] Mode 1: The light wave characteristic data includes the melanopsin protein efficiency s corresponding to different wavelengths emitted by the lamp when it is illuminated mel (λ), the measured data includes the absolute spectral power distribution E e,λ (λ), the physiological equivalent illuminance The calculation method is as follows:

[0058] E mel =∫E e,λ (λ)s mel (λ)dλ

[0059]

[0060] In the formula, dλ represents the small wavelength unit of the light wave in the integral formula, and E mel Indicates physiological equivalent irradiance.

[0061] Mode 2: The light wave characteristic data includes the spectral luminous efficiency V(λ) corresponding to the different wavelengths emitted by the lamp and the melanopsin protein efficiency s of the corresponding wavelengths mel(λ), the measured data includes relative spectral power distribution Vertical illuminance E in the direction of sight at eye level in the working area V , the physiological equivalent illumination The calculation method is as follows:

[0062]

[0063] In the formula, dλ represents the small wavelength unit of the light wave in the integral formula, Indicates the physiological equivalent natural light efficacy ratio.

[0064] Mode 3: directly call the existing physiological equivalent natural light efficacy ratio from the light wave characteristic database according to the selected lamp information And the vertical illuminance E in the direction of sight at the eye height of the working area V , then based on the known physiological equivalent natural light efficacy ratio And the illumination E in the direction of sight at the eye height of the working area V Directly calculate the physiological equivalent illuminance The premise of this calculation method is that the light wave characteristic database has pre-entered the lamp information and the corresponding physiological equivalent natural light efficiency ratio and illuminance E V This process can be done by entering historical data through multiple previous measurements and calculations to continuously fill in the data in the light wave characteristic database. Therefore, as long as the lighting engineer selects the appropriate lighting information, a rough estimate of the physiological equivalent illumination of the designed indoor light environment can be given, which is simple and efficient.

[0065] Mode 1 and Mode 2 are mainly used for the calculation of physiological equivalent illuminance during the light environment test in the building operation and maintenance stage. Mode 3 is mainly used for the general estimation of physiological equivalent illuminance in the building light environment design stage.

[0066] Based on the same invention concept, please refer to Figure 2 The embodiment of the present invention further provides a physiological equivalent illuminance measuring device, comprising:

[0067] The light source module 100 is configured to provide various common lamps suitable for indoor light environments and to construct a light wave characteristic database, wherein the light wave characteristic data of various common lamps are pre-stored in the light wave characteristic database;

[0068] The measuring module 200 is configured to perform field measurement on the indoor light environment to be detected to obtain measured data, wherein the measured data includes the absolute spectral power distribution and / or the relative spectral power distribution and the vertical illuminance in the direction of sight at the eye height of the working area;

[0069] The calculation module 300 is configured to calculate the physiological equivalent illuminance of the indoor light environment based on the light wave characteristic data of the lamps used in the indoor light environment and the corresponding measured data.

[0070] In this embodiment, the absolute spectral power distribution and the relative spectral power distribution are measured by a spectrometer, and the vertical illuminance in the eye-height sight direction of the working area is measured by an illuminometer.

[0071] Similarly, based on the light wave characteristic data of the lamps used in the indoor light environment and the corresponding measured data, there are the following three modes to calculate the physiological equivalent illuminance of the indoor light environment.

[0072] Mode 1: The light wave characteristic data includes the melanopsin protein efficiency s corresponding to different wavelengths emitted by the lamp when it is illuminated mel (λ), the measured data includes the absolute spectral power distribution E e,λ (λ), the physiological equivalent illuminance The calculation method is as follows:

[0073] E mel =∫E e,λ (λ)s mel (λ)dλ

[0074]

[0075] In the formula, dλ represents the small wavelength unit of the light wave in the integral formula, and E mel Indicates physiological equivalent irradiance.

[0076] Mode 2: The light wave characteristic data includes the spectral luminous efficiency V(λ) corresponding to the different wavelengths emitted by the lamp and the melanopsin protein efficiency s of the corresponding wavelengths mel (λ), the measured data includes relative spectral power distribution Vertical illuminance E in the direction of sight at eye level in the working area V , the physiological equivalent illumination The calculation method is as follows:

[0077]

[0078] In the formula, dλ represents the small wavelength unit of the light wave in the integral formula, Indicates the physiological equivalent natural light efficacy ratio.

[0079] Mode 3: directly call the existing physiological equivalent natural light efficacy ratio from the light wave characteristic database according to the selected lamp information And the illumination E in the direction of sight at eye level in the working area V , then based on the known physiological equivalent natural light efficacy ratio And the illumination E in the direction of sight at the eye height of the working area V Directly calculate the physiological equivalent illuminance The premise of this calculation method is that the light wave characteristic database has pre-entered the lamp information and the corresponding physiological equivalent natural light efficiency ratio and illuminance E V This process can be done by entering historical data through multiple previous measurements and calculations to continuously fill in the data in the light wave characteristic database. Therefore, as long as the lighting engineer selects the appropriate lighting information, a rough estimate of the physiological equivalent illumination of the designed indoor light environment can be given, which is simple and efficient.

[0080] Mode 1 and Mode 2 are mainly used for the calculation of physiological equivalent illuminance during the light environment test in the building operation and maintenance stage. Mode 3 is mainly used for the general estimation of physiological equivalent illuminance in the building light environment design stage.

[0081] Preferably, the physiological equivalent illuminance measuring device also includes an input module 400, which is configured to select different calculation modes and send them to the calculation module 300, so that the calculation module 300 selectively calls the absolute spectral power distribution or the relative spectral power distribution and the vertical illuminance in the direction of sight at the eye height of the working area, and calls the corresponding light wave characteristic data to calculate the physiological equivalent illuminance of the indoor light environment.

[0082] For example, when the user selects mode 1 through the input module 400, the calculation module 300 calls the absolute spectral power distribution data measured on site in the measurement module 200 and the melanopsin protein efficiency corresponding to different wavelengths emitted by the lamp in the light wave characteristic data to perform integral calculation of the physiological equivalent illumination. When the user selects mode 2 through the input module 400, the calculation module 300 calls the relative spectral power distribution data measured on site in the measurement module 200 and the vertical illumination in the direction of sight at the eye height of the working area, as well as the spectral luminous efficiency corresponding to different wavelengths emitted by the lamp in the light wave characteristic data and the melanopsin protein efficiency of the corresponding wavelength to perform integral calculation of the physiological equivalent illumination. When the user selects mode 3 through the input module 400, the physiological equivalent natural light efficacy ratio and illumination in the light wave characteristic data are directly called according to the selected lamp information to estimate the physiological equivalent illumination.

[0083] Therefore, according to the actual situation of the project, the calculation mode can be flexibly selected to calculate the physiological equivalent illumination, so as to obtain the physiological equivalent illumination of the indoor light environment conveniently and quickly.

[0084] In summary, the embodiments of the present invention provide a method and device for measuring physiological equivalent illumination, which can quickly calculate the physiological equivalent illumination of the indoor light environment by using known light wave characteristic data and measured data obtained by field measurement, thereby solving the problem of imperfect physiological equivalent illumination measurement methods at present. In addition, the present invention also provides a variety of calculation modes, and can flexibly select appropriate calculation modes to calculate the physiological equivalent illumination according to the actual situation of the project, thereby conveniently and quickly obtaining the physiological equivalent illumination of the indoor light environment.
