Abstract
The invention discloses a method for detecting a mesopic vision photometric value and a double-photometric detector thereof. The method comprises a step of adopting a photometric detector which is corrected by a photopic vision visual curve, and a photometric detector which is corrected by a scotopic vision visual curve. The method is characterized by measuring background luminance B under a mesopic vision environment condition by a luminance meter during measurement, and finding out the maximum value of luminous efficacy according to the background luminance B, thus determining the proportion of the scotopic vision visual curve and the photopic vision visual curve; and displaying the mesopic vision photometric value under the background luminance by computation according to the proportion of the scotopic vision visual curve and the photopic vision visual curve. The double-photometric detector which is obtained by the method for detecting the mesopic vision photometric value can measure the photometric value under mesopic vision environments, and can correspond with the human eye perception under the mesopic vision environment particularly at the time of designing road lighting, landscape lighting, or lighting of low-luminance trenches and tunnels, thus ensuring the optimum ambient lighting.
Description
Technical field
The present invention relates to a kind of luminosity Detection Techniques, particularly a kind of method and two photometric detector thereof of surveying photometric quantity of mesopic vision.
Background technology
Human eye is different to the sensitivity of the radiation of various wavelength, and it can experience the visible light of 380～760nm scope.When rays pass through lens converged to the sensory cell at the retina back side, vision process had just begun.Sensory cell has two kinds, and a kind of is the columnar cell, and a kind of is cone cell, and the columnar cell is stronger than cone cell photosensitivity, and it can play sensation under very low brightness conditions, thus to night (secretly) vision play a major role.But under stronger lighting condition, its response to light is tending towards saturated, thus the columnar cell (bright) vision role is very little in the daytime.Cone cell mainly plays sensation to photopic vision and is divided into three kinds that respectively have different phytochromes again, respectively three kinds of partly overlapping wavestrips is produced response, so human eye can be told different colors.People surpass 10cd/m in brightness
2In the environment, vision plays sensation by the taper permissive cell fully, carried out a large amount of experiments and repeatedly relatively after, determine luminosity function curve under the photopic vision in nineteen twenty-four, the response of its maximum is at the 555nm place.When people are lower than 10 in brightness
-2Cd/m
2The time, just belong to the noctovision scope, mainly be that the columnar cell is worked, nineteen fifty-one has been determined the luminosity function curve under the noctovision again, its peak response value is at 507nm.The luminous efficacy at photopic vision 555nm place is 683lm/W, and the luminous efficacy at noctovision 507nm place is 1700lm/W, increases by 2.49 times.Luminosity function curve under the while noctovision [V ' (λ)] move 48nm than the luminosity function curve under the photopic vision [V (λ)] to short wavelength's direction.And from 10
-2Cd/m
2～10cd/m
2In the scope, just be called the mesopic vision scope.
All electric light sources, light fixture, luminescent device, the used photometric detector of display device test all adopt the correction of photopic vision function curve at present, the data of measuring are provided under the photopic vision condition to be used and share with this illuminating engineering of being correlated with design, if but use under the mesopic vision environment and just produce very big deviation.
As designing road lighting, Landscape Lighting, or should adopt when the tunnel of low-light level and tunnel through the measured data of the photometric detector of mesopic vision function curve correction as design considerations, like this design and implement just can with these mesopic vision environment under, human eye perceives is consistent, otherwise can cause very big deviation.
Summary of the invention
The objective of the invention is to provide method and two photometric detector thereof of the detection photometric quantity of mesopic vision under a kind of energy measurement mesopic vision environment for the deficiency that solves above-mentioned technology.
In order to achieve the above object, a kind of method of surveying photometric quantity of mesopic vision that the present invention is designed, it comprises photometric detector that adopts the correction of photopic vision visual sense curve and the photometric detector that adopts the correction of noctovision visual sense curve, when it is characterized in that measuring, earlier with the background luminance B under the nitometer measurement mesopic vision environmental baseline, B checks in the luminous efficacy maximal value according to this background luminance, and determine the ratio of noctovision visual sense curve and photopic vision visual sense curve thus, demonstrate the shading value of mesopic vision under this background luminance as calculated according to the ratio of noctovision visual sense curve and photopic vision visual sense curve.
A kind of two photometric detectors of surveying photometric quantity of mesopic vision, it comprises the photometric detector that adopts the correction of photopic vision visual sense curve, it is characterized in that it also comprises the photometric detector that adopts the correction of noctovision visual sense curve, the photometric detector of the photometric detector of photopic vision visual sense curve correction and the correction of noctovision visual sense curve is formed two photometric detectors of surveying photometric quantity of mesopic vision jointly.
Two photometric detectors by the detection photometric quantity of mesopic vision that method obtained of the detection photometric quantity of mesopic vision that obtains of the present invention, shading value under the energy measurement mesopic vision environment, particularly at design road lighting, Landscape Lighting, or adopt the measured data of photometric detector of the present invention as design considerations when the tunnel of low-light level and tunnel, go to design and implement illumination under this environment, just can with human eye under these mesopic vision environment feel be consistent, to guarantee best ambient lighting.
