Description
Technical field
The present invention relates to a kind of light and radiation meter, be mainly used in the light distribution on all directions of various types of light sources and light fixture and the measurement of Luminance Distribution.
Background technology
Distribution photometer is the instrument of the luminosity of accurate measurement light source and light fixture with angular distribution.Photometric detector in the existing distribution photometer generally adopts illumination detector, surveys the brightness value that obtains according to illuminometer on a certain direction, utilizes the illumination inverse square to concern the light intensity value that calculates on this direction.Utilize spatial light intensity to distribute and correspondingly to calculate evaluation or the illumination Design of data such as distribution curve flux to carry out light source or light fitting quality of light source or light fixture.Yet make in this way investigate be whole light source or all luminous points of light fixture on a certain direction stack and the light intensity effect that produces, and the luminous situation that can not specifically investigate light source or each luminous point of light fixture or light-emitting area is so-called brightness value.Brightness is meant the light intensity on luminophor or the reflecting body unit area, and it is a very important light quantity, is that human eye is to light source or the luminous direct sense organ of reflecting body.Being not suitable for of Luminance Distribution in the visual field or brightness range, or have extreme contrast, can cause the uncomfortable sensation of human eye or reduce the ability of observing thin portion or target that this visual phenomenon is exactly dazzle; Dazzle all has very big harm to daily life work.
Because the restriction of principle of work and technology, the luminous uneven problem of Luminance Distribution that more or less exists of light source or light fixture itself, especially emerging semiconductor LED light source or light fixture, its working mechanism has directly determined the high characteristic of its non-uniform light, and for a lot of other light sources, Luminance Distribution is very inhomogeneous also to mean the technologic defective of light source or light fixture itself probably, and uses such light source or light fixture can increase the possibility that dazzle in use occurs.Existing distribution photometer can't directly be measured the index of brightness or Luminance Distribution, also just means comprehensively and objectively to estimate light source or light fixture.
The curve of light distribution of measuring according to distribution photometer carries out also will taking into full account in the illumination Design brightness and brightness uniformity problem, Chinese national standard, International Commission on Illumination etc. respectively organize all the brightness limit of illumination Design are stipulated, but be that the brightness limit curve or the calculating of unified dazzle value are all released from light intensity, the light source that calculates or the mean flow rate of light fixture, promptly suppose light source or light fixture in same bright dipping actinal surface luminous uniformly, this and actual conditions are inconsistent, and the non-uniform light of light fixture can not be embodied in illumination Design.
In addition, in using light source or light fixture and illumination Design, what investigate is the impression of people in visual environment, on different visual angles, the luminous actinal surface of viewed light source of human eye or light fixture, luminosity even glow color all are different, and therefore a series of data or the image that only relies on light distribution to calculate is not directly perceived, also comprehensive inadequately, can not reflect the visual condition of human eye in designed lighting environment well.
Summary of the invention
In order to overcome above-mentioned defective, purpose of the present invention aims to provide a kind of distribution photometer, in with the light distribution of illumination probe measurement, under all angles, observe measured light or light fixture by electronic image pickup device, and photographic light sources light-emitting area image, electronic image pickup device can be a video camera, Electrofax, when accuracy requirement is higher, be image imaging nitometer (being called for short the brightness of image meter), use the brightness of image meter can measure the total brightness and the Luminance Distribution of various light sources or light fixture, for the detection and the illumination Design of light source or light fixture provides reliable more comprehensively, data and image more intuitively.
