When, the result automatically controlled can be modified.
Below with reference to the accompanying drawings and in conjunction with the embodiments, come describe in detail the present invention realization.
Before the embodiment of the present invention, several definition are first illustrated.
Illumination：Refer to that light source is irradiated on surrounding space or ground, the luminous flux on the illuminated area of unit.Illumination is accorded with
Number E, unit LUX (lm/m2), wherein lm is the unit of luminous flux, and 1lm represents 1cd light source in a unit solid angle
Luminous flux.Luminous flux on the illuminated area of unit is more, and illumination is just high.Illumination is a kind of physical term, for indicating illumination
The amount of the strong and weak and illuminated degree of body surface area.
Brightness：Brightness refers to (reflective) the strong and weak physical quantity of illuminator (refractive body) surface light emitting.Human eye is from a direction
Light source is observed, light intensity and the light source area ratio of human eye institute " seeing " in this direction are defined as the bright of the light source unit
Degree, i.e. luminous intensity on unit projection area.The unit of brightness is that candela/square metre (cd/m2) brightness is people to light
The impression of intensity.It is a subjective amount.It is different from illuminance, it is light intensity by the objective corresponding amount of physical definition.
The two amounts are often confused in general works and expressions for everyday use.
Luminous flux：The light quantity that light source is launched within the unit interval is referred to as the luminous flux of light source, unit lumen, lm.
<The association of brightness and illumination with it is different>
Relating dot is：The physical quantity for influenceing light illumination and brightness height is identical, i.e. luminous flux.
Difference one：
Influence light-source brightness luminous flux, be the total light flux that light source surface emissivity comes out number, the luminous energy of light source
Power is stronger, radiates the total light flux projected more.
Difference two：
The luminous flux of light illumination is influenceed, is the light that light source is radiated on face to be illuminated (such as wall, ground, job platform)
The number of flux.
Difference three：
Both positions are different, also different by external influence factor.Same light source, the luminous flux that light source surface emissivity comes out
The luminous flux of face to be illuminated (such as wall, ground, job platform) is radiated, is in quantitative relation.
<Physical significance>
What brightness was described is the luminous power of light source；What illumination was described is the size of the luminous flux suffered by illuminated object.
That is, the brightness of same light source is fixed, but is not in the illumination that different distance is produced to same object
The same.
<Luminance calculation>
The difference of luminance calculation as the case may be, computational methods are also different, are broadly divided into following several：
The point luminance calculation of spot light；The point luminance calculation of line source；The point luminance calculation of area source；The meter of average illumination
Calculate；The calculating of unit capacity；The calculating of average sphere illumination and mean cylindrical illuminance；The calculating ... of flood lighting
For example：
The point luminance calculation formula of spot light is as follows：
E=I/r2
Illumination is directly proportional to the light intensity of spot light, with square being inversely proportional for distance.
In formula：E-illumination；I-light intensity；R-distance；
The calculation formula of average illumination calculating-usage factor method is as follows：
U- usage factors in formula；Φf- last the luminous flux fallen on working face sent by light fixture, unit：lm；Φs- every
The specified total light of light source leads in individual light fixture, unit：lm；
Indoor average illumination calculates (usage factor)
Eav:Working face average illumination (lx)；N：Light fixture number；A：Work area；φ：The specified total light of light source leads in each light fixture
Measure (lm)；K：Maintenance factor；U：Usage factor.
The luminance calculation formula of other situations is not just listed one by one herein.
