During cause, the result automatically controlled can be modified.
Below with reference to the accompanying drawings and in conjunction with the embodiments, realization of the present utility model is described in detail.
Before the utility model embodiment, 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 accords with
Number E, unit LUX (lm/m2), wherein lm are the units 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
Strong and weak and the illuminated degree of body surface area amount.
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, is 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 light source surface emissivity come out total light flux number, the luminous energy of light source
Power is stronger, and the total light flux for radiating injection is 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 illumination caused by different distance 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 does not just list one by one herein.

Shown in Fig. 5, the correcting mode of error correction unit is：Corresponding brightness in illumination brightness contingency table is modified, is modified to
The dim signal that user the sends lamplight brightness to be reached, and revised illumination brightness contingency table is preserved, especially, by mistake
Poor amending unit can be single-chip microcomputer, and the single-chip microcomputer can be built in the inside of light driver chip, light driving
Device chip can be CC2530.
Specifically, after being debugged by the open loop unit with an automatic light meter as described in embodiment two to light fixture, in single-chip microcomputer
An illumination brightness contingency table can be stored, the brightness value that outdoor brightness value has a light corresponds to therewith, and error correction is just
It is the brightness value changed in illumination brightness relationship table, and is stored in relevant position.
Specifically bright, the illumination brightness contingency table of single-chip microcomputer memory storage is as shown in Figure 5.When brightness value is more than or equal to E0
And when being less than E1, corresponding brightness value is L0；When brightness value is more than or equal to E1 and is less than E2, corresponding brightness value is L1；
By that analogy, each brightness value can accordingly correspond to a brightness value.
For example, now ambient light illumination is Ex, and Ex is more than E4 and is less than E5, then corresponding brightness value now is L4,
But the brightness of current lamp is now unsatisfied with using the user of the lamp, then can adjust, into error correction pattern, light is adjusted
It is whole to brightness desired by user, it is assumed that be Lx, then preserved, such ambient light illumination is more than or equal to brightness when E4 is less than E5
Value is just changed into Lx.
