Embodiment
Specify one embodiment of the invention below.In this embodiment, light level of illumination measurement mechanism comprises the indicating mode of four application scenarioss and two level of illumination, can distinguish two kinds of light source types.
As shown in Figure 1, light level of illumination measurement mechanism is used to provide the indication alarm unit 3 of relevant application scenarios and level of illumination information and a control module 4 to constitute by the be provided with unit 2, that a measuring unit that is used to measure light illumination 1, are used to set application scenarios, level of illumination indicating mode and light source type.
Four application scenarioss that light level of illumination pick-up unit is comprised are respectively " life staying idle at home " " light reading ", and " reading and writing " and " meticulous test ", two kinds of light source types can distinguishing are natural light and light.As shown in Figure 2, for each light source type, each application scenarios all has corresponding illumination range data; But the resolution for level of illumination under the different application scene is different, shows as under the different application scene; Number corresponding to the threshold value of illumination range is different, and four kinds of situation are arranged, and is respectively 1; 2,4,3.The pairing threshold value of illumination range under the different application scene comprises lower limit, accurate lower limit, in the accurate upper limit and the upper limit one or several.All these illumination range data all are kept in light level of illumination the pick-up unit inner hardware or firmware.Among Fig. 2, the illumination range of " life staying idle at home " has only been established a lower limit, and this does not also mean that definitely there is not the upper limit, but because the maximum brightness of throwing light in the daily life unlikely exceeds the required illumination range of life staying idle at home at ordinary times, so needn't establish the upper limit.Need to prove that in addition Fig. 2 only illustrates that the pairing illumination range of each application scenarios is different, and does not represent the relative position between these illumination ranges.
The indicating mode of two level of illumination is respectively " pointing-type " and " alarm mode ".
The light illuminance information is indicated by the LED lamp and the attached literal (too secretly, dark partially, suitable, bright partially, too bright) thereof of rubescent, yellow, green three coloured light.The used level of illumination pilot lamp of each different application scene can separate (like Fig. 3) also can shared (shown in Fig. 4 right side).If adopt the mode on Fig. 4 right side, so, also should comprise application scenarios pilot lamp (shown in Fig. 4 left side), and the indication of the illumination under the different application scene must be staggered in time.Certainly also having other alternatives, do not set forth one by one at this, for the sake of simplicity, is the example explanation with situation shown in Figure 3 below.
Warning is realized by hummer.
When light level of illumination pick-up unit operate as normal, the user sets the indicating mode and the light source type of level of illumination through unit 2 is set, and wherein light source type is set by the toggle switch that is provided with in the unit 2.
If the indicating mode of level of illumination is " pointing-type "; The light illuminance information that control module 4 records measuring unit 1 through the light illumination range of suitably handling all application scenarioss under back and the current light source type relatively, indication alarm unit 3 indicates current light illumination for the usable condition of all application scenarioss (as too bright, bright partially, suitable, too dark, dark partially etc.) according to comparative result.If the indicating mode of level of illumination is " alarm mode ", so, the user must set the practical application scene through unit 2 is set earlier.Afterwards; The light illuminance information that control module 4 records measuring unit 1 through after suitably handling only with the current light source type under that application scenarios of setting of user the light illumination range relatively, indication alarm unit 3 is indicated the usable condition (as too bright, bright partially, suitable, too dark or partially secretly) of that application scenarios that current light illumination sets for the user according to comparative result.
For each application scenarios, the concrete condition when the pairing illumination range of the light illumination that records and this application scenarios compares is following.
For " life staying idle at home ",, light or glimmer corresponding to the red light of literal " too dark " so and change until state if illumination is lower than lower limit; If illumination is higher than lower limit, lights or glimmer corresponding to the green light of literal " suitable " and change until state.
For " light reading ",, light or glimmer corresponding to the red light of literal " too dark " so and change until state if illumination is lower than lower limit; Be lower than the upper limit if illumination is higher than lower limit, light or glimmer corresponding to the green light of literal " suitable " so and change until state; If illumination is higher than the upper limit, lights or glimmer corresponding to the red light of literal " too bright " so and change until state.
For " reading and writing ",, light or glimmer corresponding to the red light of literal " too dark " so and change until state if illumination is lower than lower limit; Be lower than accurate lower limit if illumination is higher than lower limit, light or glimmer corresponding to the amber light of literal " partially dark " so and change until state; If illumination is higher than accurate lower limit and is lower than the accurate upper limit, light or glimmer corresponding to the green light of literal " suitable " so and change until state; If illumination is higher than the accurate upper limit and is lower than the upper limit, light or glimmer corresponding to the amber light of literal " bright partially " so and change until state; If illumination is higher than the upper limit, lights or glimmer corresponding to the red light of literal " too bright " so and change until state.
For " meticulous test ",, light or glimmer corresponding to the red light of literal " too dark " so and change until state if illumination is lower than lower limit; Be lower than accurate lower limit if illumination is higher than lower limit, light or glimmer corresponding to the amber light of literal " partially dark " so and change until state; If illumination is higher than accurate lower limit and is lower than the upper limit, light or glimmer corresponding to the green light of literal " suitable " so and change until state; If illumination is higher than the upper limit, lights or glimmer corresponding to the red light of literal " too bright " so and change until state.
In addition, when the indicating mode of level of illumination is " alarm mode ", if corresponding to the red light of literal " too dark " light or one section short period T1 of state continuance (as 3 seconds) of glimmering constant, start so and report to the police; If corresponding to the amber light of literal " partially dark " light or one section long period T2 of state continuance (as 10 minutes) of glimmering constant, start so and report to the police; If corresponding to the green light of literal " suitable " light or state continuance a period of time T3 (as 10 seconds) of glimmering constant, close green light so not influence user's operate as normal; If corresponding to the amber light of literal " bright partially " light or one section long period T4 of state continuance (as 10 minutes) of glimmering constant, start so and report to the police; If corresponding to the red light of literal " too bright " light or one section short period T5 of state continuance (as 3 seconds) of glimmering constant, start so and report to the police.Level of illumination information is only by the indication of pairing that group of current application scene LED lamp.When taking place to report to the police, the user can adjust light illumination, body posture or application scenarios according to indication information and meet the requirement of actual operating position to guarantee the light illumination of target area.Time period T1, T2, T4 also can be the value that changes with the degree that the actual light illumination and the pairing illumination range of application scenarios of user's setting depart from mutually with T5.
Alarm mode is specially adapted to the continuing to monitor of target area light illumination bothered to minimum degree the user and learnt normally, work or live when light is suitable; When light is improper, remind the user to adjust light luminance, body posture or application scenarios the most in time.
It is to be noted; According to level of illumination pick-up unit of the present invention and method; The measurement of its illumination can be continuous or periodic in time; Various indication information and warning messages about illumination can be in time continuous (continue bright, or the sound that continues) like pilot lamp or intermittent (like the pilot lamp flicker, or " tick. tick " sound).In addition, also can use literal, symbol or pattern on the LCD screen (LCD) to show about the indication information of application scenarios and illumination to replace the LED lamp among Fig. 3 or Fig. 4.
Though scheme described in the embodiment of the invention is used for measuring and guidance light illumination, obviously, this scheme also can be used for other situation that need measure and indicate, like temperature, humidity etc.
Should be noted that; The foregoing description is used for explanation and unrestricted the present invention, and, through combining specific embodiment to describe to the present invention; For skilled personage in the present technique field, according to the narration of preceding text make many to substitute, revise and change will be conspicuous.Therefore, substitute, revise and when changing in the spirit that falls into appended claim and the scope, should be included among the present invention when such.In addition, should any reference marker in the claim be interpreted as the protection domain of restriction claim.
