It is recorded in the first corresponding table with reflectivity, and the lower brightness value LR11 (difference) measured of this corresponding setting condition.
Confirm whether the different reflectivity of same distance and same brightness has all been tested in step S304, if not testing,
Then it is step S305: changes reflectivity.For example, distance H1, the corresponding reflectivity of brightness L11 are changed to R2, measurement of going forward side by side (is repeated
Step S302, S304, S305).Conversely, carrying out step if same distance and the different reflectivity of same brightness have all been tested
The luminance test of S306 confirms.
Confirm whether the different brightness of same distance have all been tested in step S306, if not testing, for step S307:
Change brightness.Light out part changes in multiple brightness, changes the brightness of transmitting light.For example, will distance H1, brightness L11
After corresponding reflectance test is complete, brightness is changed to L12, reflectivity be changed to R1 measured (repeat step S302, S304~
S307).Conversely, carrying out the distance test confirmation of step S308 if the different brightness of same distance have all been tested.

Formula is completed, also that is, reflectivity and the second brightness can be used different modes and acquires.For example, control unit utilizes lookup table mode foundation
First corresponding table finds reflectivity, and then control unit utilizes formula calculation, is calculated using reflectivity and first distance
Second brightness.Whereby, the stage is exported in the second brightness, the foundation of the first corresponding table can be cooperated, by control unit by received ginseng
Number using table look-up and formula calculate in the way of achieve the purpose that adjustment illumination brightness.Partially using looking into second brightness export stage
The mode of table can save operation time.
In another embodiment, after tabling look-up and finding out above-mentioned reflectivity, control unit can further according to reflectivity, first away from
From the brightness for calculating environment light with the first illumination.Then brightness of the control unit according to reflectivity, first distance and environment light
To determine the second brightness.Whereby, lamps and lanterns can adjust illumination brightness according to illuminated surface reflectivity and environment light.For example, working as lamp
The A desktop of tool from an indoor dark place moves to the B desktop by window position, and ambient brightness and desktop reflectivity all change, lamp of the present invention
The light adjustment mode out of tool can change in response to the change of desktop reflectivity and the bright-dark degree of lamps and lanterns local environment.
Fig. 8 is the flow chart for establishing the second corresponding table.As shown in figure 8, list establishment stage additionally comprises the second corresponding table
It establishes.In step S311: setting initial environment illumination, distance and reflectivity.Such as shown in table 2, setting initial environment illumination E1,
Distance H1 and reflectivity R1.Whether reach object illumination in step S312 confirmation illumination, if miss the mark illumination, for step
S313: change brightness.Conversely, carrying out step S314 if having reached object illumination: being recorded.By initial environment illumination, away from
It is recorded in the second corresponding table from reflectivity, and corresponding lower the second the adjusted brightness L21 of this setting condition.
Then confirm whether all ambient light illuminations of same distance and same reflection rate have all tested in step S316, if not
It tests, is then step S317: changing ambient light illumination.For example, distance H1, the corresponding ambient light illumination of reflectivity R1 are changed to E2,
It goes forward side by side measurement (repeating step S312~S314, S316~S317).Conversely, if all environment of same distance and same reflection rate
Illumination has all been tested, then carries out the reflectance test confirmation of step S318.
Confirm whether the different reflectivity of same distance has all been tested in step S318, if not testing, for step
S319: change reflectivity.For example, reflectivity will be changed to R2 after distance H1, the corresponding ambient light illumination of reflectivity R1 test,
Ambient light illumination is changed to E1 and is measured and (repeat step S312~S314, S316~S319).Conversely, if same distance it is all anti-
It penetrates rate all to have tested, then carries out the distance test confirmation of step S320.
Whether all tested in step S320 confirmation different distance, if not testing, for step S321: changing distance.
For example, distance is changed to H2, reflectivity is changed to R1, and ambient light illumination is changed to E1 and is measured (repetition step S312~S314, S316
~S321).Conversely, completing the second corresponding table if all distances have all been tested.It should be understood that step S316~S321 is parameter
It is stored in an exemplary illustration of the second corresponding table, sequence can be adjusted to different order according to measurement step.
Control unit preferably corresponds to table in the preceding execution correction program that parameter measures to establish second, subsequently enters parameter amount
The survey stage.It measures and completes to parameter, export the stage into the second brightness.It is found in the second brightness export stage in the second corresponding table
