Embodiment
Ultraviolet detector (UV detector) is the detecting device that a uitraviolet intensity in can corresponding received light produces corresponding current signal or voltage signal.See also Fig. 1, it is that (wherein the directions X coordinate is represented ultraviolet index for the graph of relation of the received uitraviolet intensity of a ultraviolet detector and its output current size, Y direction coordinate is represented output current (milliampere), K represents the uitraviolet intensity in the sunshine), find out by knowing among the figure, the uitraviolet intensity that it receives and its output current are a positive correlation, therefore, the electric current that only needs ultraviolet detector 11 is exported offers a comparer 12 (as shown in Figure 2), can learn just whether the uitraviolet intensity in the environment surpasses a threshold value.And the present invention just can utilize this information to activate down array apparatus automatically, and then reaches the purpose that solves FAQs.
At first see also Fig. 3, it is applied to preferred embodiment functional block diagram on the automobile for the automatic active device that will have a uitraviolet intensity measuring ability, wherein this ultraviolet detector 11 can be loaded on any on the car can be by irradiate light part (for example on roof, windshield or the rear window), and the output current of ultraviolet detector 11 can provide the non-glare rear-view mirror module 13 to this automobile to use.Owing to be when rather dark, the strong illumination of front vehicle is on rearview mirror the time, can make the driver produce dazzling glare phenomenon, and glareproof mirror is convenient to utilize optical inductor 131 on it to detect the visible light intensity in rear this moment and correspondingly send one and control signal to electrically color changing rear- view mirror 132, and 132 pairs of electrically color changing rear-view mirrors should control signal control and change its light reflectivity, and then visual intensity in the wings is when strengthening and reduce its light reflectivity (for example color being changeed dark), and then reaches anti-dazzle function.But, when daytime, sunlight was strong, above-mentioned variable color just need not exist with the function that changes reflectivity, therefore, just the output current of this ultraviolet detector 11 can be sent to this comparer 12 compares, thus, when detected uitraviolet intensity during less than a threshold value (the meaning output current is less than a threshold value), just be judged as evening or light is faint, this moment, comparer 12 made electrically color changing rear-view mirror 132 change its light reflectivity to control that should control signal, and then light intensity in the wings is when strengthening and reduce its light reflectivity.Otherwise, when detected uitraviolet intensity during greater than a threshold value (the meaning output current is greater than a threshold value), just be judged as daytime or bright and clear, this moment, comparer 12 just made electrically color changing rear-view mirror 132 stop control that should control signal is changed the action of its light reflectivity, and then its light reflectivity is maintained at a predetermined value, to avoid its unnecessary start.
Moreover, automatic active device with uitraviolet intensity measuring ability also can be applicable on the head lamp module 14 in this automobile, wherein this head lamp main body 141 is driven and luminous by power supply 140, and controlled switch circuit 142 then is connected between this head lamp main body 141, power supply 140 and this ultraviolet detector 11.And when electric current small offence one threshold value of ultraviolet detector 11 this comparer 12 that exports to, comparer 12 just makes these controlled switch circuit 142 conductings and makes this head lamp main body 141 driven by power supply 140 and luminous.On the contrary, when this ultraviolet detector 11 detected uitraviolet intensities during greater than this threshold value, comparer 12 will make this controlled switch circuit 142 be in to open circuit and make this head lamp main body 141 stop luminous.Thus, be ultraviolet ray when faint (promptly rather dark), head lamp main body 141 will be opened and luminous automatically, otherwise then extinguish automatically.And except head lamp, automatic active device of the present invention also can apply on other Vehicular lamp modules such as fog lamp, indicator, cowl lamp, and its means and above-mentionedly there is no too big difference are not so repeat them here.
In addition, automatic active device with uitraviolet intensity measuring ability also can be applicable to the abat vent module 15 in this automobile, this module consists predominantly of an electric sunshading curtain main body 151, it is driven by power supply 150 and is in and closes receiving state or and activate deployed condition, control circuit 152 also is subjected to the control of this comparer 12, and in the conducting and make this electric sunshading curtain main body 151 driven by power supply 150 and be in this activations deployed condition during greater than a threshold value of ultraviolet detector 11 detected uitraviolet intensities, and make this electric sunshading curtain main body 151 be subjected to power supply 150 drivings during less than this threshold value and return back to this and close receiving state at detected uitraviolet intensity.Thus, when being that sunlight is strong, electric sunshading curtain main body 151 transfers this activation deployed condition automatically to, otherwise then returns back to receiving state.
Moreover, for effectively isolating light, the automatic active device that the inventor will have the uitraviolet intensity measuring ability is applied on an electrochromics glass 16 or other electrochromics printing opacity object, has on the object of door and window and this electrochromics glass or electrochromics printing opacity object can be arranged at the vehicles such as vehicle, ships, aircraft or buildings etc.As shown in Figure 4, the electric current of being exported when ultraviolet detector 11 is during greater than a threshold value, comparer 12 just can send a drive signal changes the light transmittance of electrochromics glass 16 objects such as printing opacity such as electrochromics such as grade, and then when uitraviolet intensity strengthens, reduce its light transmittance (for example color being changeed dark), make Che Nei or the indoor function that reaches automatic sun-proof.
Moreover, be energy rapid reaction virtual condition, automatic active device with uitraviolet intensity measuring ability can be applied on the window and sunshading board of a controlled keying, have on the object of door and window and the window of this controlled keying and sunshading board also can be arranged at the vehicles such as vehicle, ships, aircraft or buildings etc.The electric current of being exported when ultraviolet detector 11 is during less than a threshold value, comparer 12 just can send a drive signal makes window open automatically and sunshading board (curtain) is taken in, and then when uitraviolet intensity is not strong, make Che Nei or the indoor function that reaches ventilation, daylighting.
In addition, see also Fig. 5 again, for above-mentioned automatic active device and controlled device thereof with uitraviolet intensity measuring ability utilized controller local area network's bus (Controller Area Network Bus, abbreviation CAN Bus) mode is reached building of system and is put, can know by figure and to find out, signal between the functional unit of all small-signals transmits and all can finish by controller local area network's bus 50, thus, systems organization will be arranged and expand easy profit.Certainly, except can using controller local area network's bus (CANBus), also can use the vehicle LAN bus (VAN BUS) similar to carry out the transmission of signal with it.As for the signal channel transmitted, except the wired mode of tradition, also can use Wireless transmission mode to finish, and then reach the effect of simple installation.
In sum, the fundamental purpose of the certain attainable cost invention of this case.Certainly, above-mentioned ultraviolet detector also has the uitraviolet intensity in the corresponding received light and produces the pattern of voltage signal.
