The present invention is provided with a low battery indicator lamp to provide extra illuminator information, with visually Sending needs to change the signal that one or more battery supplies electrical power to system.The present invention is also supplied provided with one The visual detector of detecting system, it can be at any time and under any illuminator work pattern User is allowed to select.By that can be lighted and/or specific with one from detection function (such as depressing one to switch) Order or color pulses trigger one or more lamps, to confirm that all subsystems in illuminator are complete Can normal work.

A particularly useful feature is night light fixture or night signal in the illuminator that the present invention is provided Lamp, it optionally can be started or disabled by user.When starting, the night signal lamp can adopt low Electric power and low lumen flash of light form, are flashed, and then save battery electric power with the time interval that appropriateness is separated. When user or should not need night signal lamp, user only can be stopped by press push button easily Use this function.If for example, user uses the night-light of flicker dislike (such as in will be) during sleep Person optionally disables this night signal lamp function.

Such as described more fully below, the luminescent system can quickly and easily be attached, carry or with it His mode is installed on almost all of object, includes lived or abiotic object.These are right As not only comprising action servicing unit, also comprising using the helmet, the head band of head lamp, footwear, Animal halter rope and neck ring, motion are used, the peculiar to vessel and open air such as bicycle use product and clothing and belt Or telecontrol equipment.In some application modes, the illuminator is used in halter rope, neck ring and the like When can be used to determine pet or the position of other animals in the dark.

Although it is contemplated that going out many application modes of the illuminator, a particularly useful application mode is Using auxiliary walking utensil on, and be conducive to use on hand-held crutch and walking stick.Reason has for it There are the part of miniature sizes and the advantage of small portable, one embodiment of the invention is highly suitable for hand-held On crutch and walking stick, and do not have the housing of Large heavy or the electronic component of weight to tie down crutch or make User.

In one embodiment, the illuminator includes three kinds of general job patterns, that is, opens, closes And test pattern.By the short time or for a long time, contact presses two instantaneous touching formulas or pressed these patterns Button formula switch one of and select.For example, by short depression and discharging one " closing " switch, control The microprocessor of all illumination functions enters a sleep or standby mode, wherein except microprocessor most Outside low-power, all electronic equipments and lamp are all closed.This pattern is used for setting microprocessor In " sleep " of low-power or standby mode to save battery electric power, wherein within the system without lamp Being lit, and being sent to the electric power of the microprocessor can be ignored or minimum.This pattern can be at this Illuminator is selected when will not periodically use.

When the closing switch is pressed, user clearly can visually be notified the illuminator and enter Enter to close or sleep pattern, for example, pass through pulsed or flicker red colored lamp, such as red LED. The red LED sparkling once, twice, three times or more, to issue the user with the illuminator The pent signal when starting closing switch.Flicker or three red colored lamps of pulse excitation are best suited for Implement this purpose.Can be often used in the object attached by the system thereon or to be placed to vehicle, In aircraft, railway carriage transport or store wardrobe or do not need light fixture space among when using this close Or sleep pattern.The illuminator can easily cancel its sleep pattern, and only be opened by pressing one Switch and be arranged in binding mode.

When press-started switch, user clearly can visually be notified the illuminator Into " unlatching " work pattern, for example, pass through pulsed or flicker green LED.The green LED sparklings once, twice, three times or more, are being started with issuing the user with the illuminator Open the signal being unlocked during switch.Flicker or three green lights of pulse excitation are best suited for implementing this Purpose.

In short depression and when discharging the unlatching switch or button, a microprocessor leaves sleep or standby Pattern, electronic equipment and the sensor of the system switch to working condition.It is arranged on out in the system When opening pattern, three or more independent or " son " operator schemes can be provided with.

One kind in this kind of " in use " work pattern is night signal lamp pattern.In such a mode, And in low illumination or no environment or ambient light and action very little or when not sensing action, it is all If the colored lamp of blue led is by with the of short duration flicker of time interval for example per several seconds.Flashing every time About 5 second time is spaced between pulsed light, contributes to user in low-light level or is not having light In the case of confirm the position of object attached by the illuminator.

This pulsed LED can work when user sleeps under low electric power level, to save electricity Pond electric power simultaneously minimizes light luminance.As described below, dislike if user flashes to night, this Night signal lamp pattern is optionally disabled or closed.In one embodiment, closed by pressing one Button for quite a long time (such as several seconds), can continuously and repeatedly be turned on and off night signal lamp Pattern.For example, night signal lamp pattern can be disabled by pressing X button 5 seconds.Pass through pressing again The long period of X button one (such as 5 seconds), you can enable night signal lamp pattern again.

Another subjob pattern under this pattern is to sample or inquire about ambient light by microprocessor cycle The aggressive mode of the action of level and lighting device.If sensing low-light level or without illumination level and sense Measure the minimum level of action, then by the microprocessor open such as white light LEDs one or more are bright Bright illumination path lamp, to illuminate course.

The microprocessor can be sensed to the ambient light level that is provided by a light sensor and by an action The action level input signal that device is provided is sampled, and if it meets predetermined extent, the microprocessor Device will light the plurality of scheduled time of White LED one.In an application examples, this time is about 15 seconds, But can programmed or selected any other reasonable time, such as 10 seconds to one minute or longer.

If microprocessor detects a predetermined low light position in any time that White LED illuminates path An accurate and minimum action level, microprocessor can maintain to illuminate path another a period of time, for example, 15 Second.If however, the ambient light any time point interim when illuminating path increases above a predetermined level And/or a predetermined action level is down in the action detected, micro- place after an of short duration time delay Predominating path illumination will be closed by managing device, and wait one is lower before the path light fixture is lighted again Light level and/or higher action degree.

If that is, ambient light increases above default minimum level during path is illuminated, or moving Make degree less than default minimum level, or two kinds of situations are when all occurring, from that moment on the path Light fixture will maintaining lights another section of predetermined lighting time, such as 15 seconds, and be then switched off.This delay Illumination provides the of short duration path illumination time, to be used as greeting lamp for user, rather than Turn Off Path illumination suddenly in the middle of illumination period.

If the ambient light sensed during path illumination increases above minimum level and met in of short duration The action degree that guest is sensed during illuminating exceedes minimum level, and microprocessor will restart path Light illumination mode is to its complete job state.Extend welcome's lighting hours of path illumination as preventing because The of short duration buffering that path illumination is lost under (such as) such as light beam from headlight for vehicles Time.

As described above, when having detected sufficient ambient light, the illuminator will avoid opening path photograph It is bright.This feature can significantly save battery electric power.

The illuminator can include a test pattern, and it can enter at any time and under any work pattern Enter this pattern.This pattern can visually allow user to confirm that the illuminator is normal work.One In example, can depress the unlatching switch and keep pushing a long period (such as three seconds, four seconds, five Second is longer).It can be operated well within five seconds.

It is depressed (such as) five seconds once this is released the button or switched, the illumination of its main path will be lighted The of short duration time (such as five seconds) of several seconds.During this path illumination, it can also indicate one or more Lamp flashes or pulse excitation.The LED of two different colours can sequentially flash, or allow single dual-colored LED (such as green or red LED) alternately flashes during of short duration (five seconds) interval time red herein Color and green.

Another useful feature of the illuminator is low battery indicator lamp, and it is in a predetermined residue electricity Measure and start under level, for example, when remaining battery electric quantity can make main path illumination with all strength or constant When being worked under electric power level 30 minutes, the low battery indicator lamp starts of short duration flicker.In an embodiment In, when battery reaches one first low deposit level, a special low power indicating lamp (such as red LED of short duration flicker will) be started, flicker in such as every two seconds is once.

When battery is further consumed to a predetermined second low deposit level, the low battery will be promoted to indicate Lamp in extremely rapid succession flashes two or more times, and flicker in such as every two seconds is once.When electric power is down to one Three compared with low level, then stop the power consumption of battery, to prevent electric power excessive loss.

It is real while following illuminators provide significant visual information amount and feed back to user The user interface on border can be quite succinct and be readily understood by operation.Two instant shut-ins can allow user to illuminate System is arranged in " unlatching ", " closing " or test pattern, to control night signal lamp to work. One double-colored " red/green " LED or a red LED and a green LED are dodged when press-started button Sparkle green glow three times, and flicker feux rouges three times when X button is pressed.This mode is confirmed with visual manner The working condition of illuminator, and confirm that the system is effective when pressing a wherein button.One Special red LED provides low battery and indicates function, and special blue led is believed there is provided night The function of signal lamp.

To further appreciate that the present invention, preferred embodiment is lifted below, coordinates schema, figure number, this is sent out Bright specific constitution content and its effect reached describe in detail as follows.

As shown in Figure 1, Figure 2 and Figure 3, the connector 14 is fixed on the rear wall section 20 of a housing 24.One Adjustable locking ring 26 is lined with a soft rubber or foam material 30 for the movable objects that clamp and coincide 12 outer surface.One detachable latch 34 includes an eccentric control rod 36, and it is selectively engaged and released A ring or clasp 40 are put, so as to open and close a zigzag anchorage part 42.

The rear wall 20 can be comprising one for the removable of the battery of installation and the removal supply power supply of illuminator 10 Wall portion.The sleeve pipe 18 and the housing 24 can be integrally formed or with identical component by durable lightweight plastic material Shaping.Some openings or through hole are formed with the housing 24, it is (all for housing one or more light-emitting lamps Such as path illumination light fixture) and indicating lamp and switch actuator.

That is, as shown in Figure 1, Figure 3, the bottom wall 44 of the housing 24 includes one or more paths Illuminator 46, such as one or more white light LEDs 46.The roof 50 of the housing 24 includes a low electricity Amount instruction LED 54 (red), in one night signal designation LED 56 (blueness) and a Switching Two Color indication LED lamp 60 (green/red).

The roof 50 also includes an opening used for optical sensor (such as photistor 64).Or Person, the photistor can be installed on the rear wall 20." unlatching " switch 70 set by the present invention can For one it is instantaneous touch button switch, and it is also such that " closings " set by the present invention, which switchs 72,.It is of short duration Pressing unlatching switch 70 makes the flash greens of LED 60, and the short depression closing switch 72 makes this LED 60 flashes feux rouges.

As shown in figure 4, the illuminator 10 is controlled by a microprocessor 78, the microprocessor 78 is by example Power supply supply electric power such as including one or more battery 16.In one embodiment, it can be used three AAA batteries, and be used in combination with an existing voltage regulator 82.When battery is loaded, microprocessor Firmware in device 78 is initialized and the night signal indicator lamp 56 is set as into default startup or mould is enabled Formula.User can switch 72 1 long periods or several seconds (such as 5 seconds or longer) by pressing the X button Time and disable and close the night signal indicator lamp 56.X button switch 72 1 is pressed again When long period or several seconds (such as 5 seconds or longer), you can reactivate the night signal work pattern And extinguish the night signal indicator lamp 56.This enables and disabled function can be sequentially from the illuminator One of open mode or close pattern are repeated.

The action sensor that is moved through of illuminator 10 is detected, a such as three axis accelerometer Circuit 84, for the action of three dimensions in detecting space.

One low battery circuit for detecting 88 makes LED 54 reach that one presets low electric power/electricity in the plurality of battery 16 Glisten or flash when pressing level.

As described herein, the microprocessor 78 is programmed to control the illuminator 10.The microprocessor One programmed logic example of device 78 is shown in Fig. 5 a, Fig. 5 b and Fig. 5 c flow chart.According to Fig. 5 a, Fig. 5 b and Fig. 5 c flow chart, for provide input signal to the microprocessor 78 and for based on from The output signal of the microprocessor 10 operate the representative electronic circuit of the illuminator 10 be shown in Fig. 6, In Fig. 7.

As shown in Figure 6, Figure 7, the microprocessor 78 receives some by hardware and the control illuminator 10 The handled input signal crossed of the related software of work, and its various effect is discussed further below. One battery assembly 90 includes one or more battery 16 (Fig. 4), to supply power to a normal voltage Adjust circuit 82 (Fig. 4).Except all LED directly powered by battery 16 and the low battery are detected Outside circuit 88, the output signal from the voltage regulator 82 supplies power to all electronic equipments. This design is with the advantage that smaller, lighter and relatively inexpensive voltage regulator can be used.

The switch 70 of releasing the button is pressed by moment, an interrupt service routine opens the microprocessor 78 With the LED 60, so that it is flashed with green glow or glistened three times, to inform that the illuminator has been enter into " unlatching " work pattern.In depress this release the button 70 when, the software in microprocessor 78 shines this Bright system 10 is switched to " unlatching " pattern worked by "Off" mode.Under this open mode, The phototransistor circuit 92 is periodically enabled with the low battery circuit for detecting 88, such as every 50 milliseconds Enable once, to these circuit samplings or to investigate.Compared with the continuously use of monitoring electric power, Battery can be extended by carrying out investigation to these circuits.Sampled or investigation circuit and three axle The action level value that accelerometer circuit 84 is provided can be together periodically as the microprocessor 78 Input signal.Above-mentioned investigation can be carried out under any appropriate intervals, such as every 50 milliseconds are carried out once.

When user selectes open mode and detects ambient light less than a predetermined level and while detects Action be higher than a predetermined level when, the plurality of path illumination LED 46 lights (such as) 15 seconds, with The front of housing 24 sends path light from the housing 24 with a downward angle.

In the photistor 64 and the three axis accelerometer circuit 84 in interval time the last period (15 seconds) Period is sensed under conditions of the predetermined level of ambient light and action, in each minor tick of path illumination At the end of time, each LED will continuously send out another section of interval time (15 seconds) of path light.If ring Border light level increases above a predetermined default value or the action level be down to a predetermined default value with Under, or both situations, when all occurring, the microprocessor 78 will close the plurality of path illumination LED 46 And continue these levels of sampling.If ambient light level drops to below its default value and the action level Its default value is increased above, the microprocessor 78 will light the plurality of predominating path illumination LED again 46。

Fig. 7 shows that one is used for the three axis accelerometer circuit 84 of three axis accelerometer.This accelerometer is commercially available From ST Micro companies.What the three axis accelerometer circuit 84 can be made comprising one group with MEMS technology Three micromechanical capacitors, wherein change of the capacitance of the plurality of electric capacity to outside acceleration force is made instead Answer and change.This three axis accelerometer circuit 84 includes hardware and built-in firmware, with detecting vibration simultaneously Measure the action on three directions.

One interface commonly used at present (such as I2C communication interfaces) is arranged on microprocessor 78, three axles and accelerated Degree is counted between circuit 84 and the accelerometer disrupted circuit for connecting the input of microprocessor 78.This leads to Communication interface and disrupted circuit provide one be used in act occur when acts of determination with for by information transmission To the system of the microprocessor 78.

The microprocessor 78 sets an action by the I2C interfaces at the three axis accelerometer circuit 84 Threshold value.Detected in the three axis accelerometer circuit 84 and the accelerometer circuit internal memory is stored in more than one When the action of interior predetermined threshold or vibrations level, the three axis accelerometer circuit 84 enables connection, and this is micro- One disrupted circuit of processor 78.This correspondingly makes the microprocessor firmware enable one by using the I2C Interface from the three axis accelerometer circuit 84 to ask to obtain and receive the interruption service of act bit calibration information Program.This notifies the microprocessor is existing to have two kinds of one kind enabled in situation, should for opening Path light fixture 46.

This second condition that must start up is is detected and photosensitive through this based on the photistor 64 The treated ambient light level of transistor circuit 92.In the next output end of microprocessor of fixed interval A low power state is switched to, starts the photistor.Regularly photistor sampling can for this Extend battery.

If the ambient light level that the phototransistor circuit 92 is sensed drop to a predetermined level with Under, and if the action level that is detected of the three axis accelerometer circuit 84 is default less than one or pre-determined bit On time, the firmware will start a microprocessor output signal, so that the night signal lamp 56 is predetermined with one Speed (such as every five seconds for example once) starts flicker.This can help user to confirm the illumination in the dark The position of light fixture 10.In " unlatching " work pattern and ambient light level from phototransistor circuit While signal is higher than a predetermined threshold, the firmware in microprocessor 78 will ensure that the plurality of path illumination LED 46 will not be acted on outside its predetermined operation time (such as 15 seconds).

As shown in Figure 6, the low battery circuit for detecting 88 is located at the low battery circuit for detecting 88 comprising one Interior divider.Output end from the divider is connected to an analog-to-digital of the microprocessor 78 Input.The low battery circuit for detecting 96 is by switching one of output end by the microprocessor 78 Low electric power or ground state and be periodically turned on, to complete the low battery circuit for detecting.

The output end of the low battery circuit for detecting 88 is connected to an analog-to on the microprocessor 78 Word input, periodically to be sampled and judged the voltage actually remained in the grade battery.In When electricity is down to below one first predetermined level, the low electric power LED 54 can be with a set rate (for example Every two seconds are once) flash or glisten., should when electricity is dropped to below one second predetermined voltage level Low battery LED 54 (such as) quick continuous flickers in every two seconds are glistened twice.When electricity drops to one When below the 3rd predetermined voltage level, the microprocessor 78 stops all use situations of battery to avoid Battery leakage loss.

Whether to judge the illuminator in all one's effort working condition, can by press and pin the unlatching by 70 1 sections of longer times of button switch (such as 5 seconds or longer) and start a test pattern.It is default in this After time, path illumination LED 46 will open one end longer time (such as five seconds), and with Alternate sequential illumination red and green LED 60.This test function can be from being turned on and off work pattern In a kind of startup.After testing is complete, its previous operation mould of the auto-returned of illuminator 10 Formula.This function is resided on the software in microprocessor 78.

To close the illuminator or being set in standby or park mode, user can depress this moment X button switched for 72 1 of short duration times to start the interrupt service routine, and then promoted microprocessor 78 Start the red LED 63 and it is flashed or is glistened (for example) three times, to confirm the pattern of the system Closing is switched to from unlatching.In such a mode, the microprocessor 78 enters a sleep pattern to save Electric power, but can be pressed by moment this release the button switch 70 and enable.Moment and of short duration finger are less than one Or two seconds.

It can be easy to by the built-in connector 108 of plate of one external programmer device of connection to the microprocessor Device 78 is programmed.A connector 110 is only used during airborne microprocessor is programmed.The microprocessor Program voltage exceedes the maximum voltage allowed of the three axis accelerometer circuit 84, with during programming by The connector 110 removes a pecker, prevents elevated programming supply voltage from damaging the accelerometer circuit 100。

The most preferred embodiment hitherto being susceptible to has been disclosed in the present invention.Can be to this under above-mentioned teaching Various modifications and changes are made in invention.It can therefore be understood that can be differently configured from above under scope Specific descriptions mode implements idea of the invention, method and system.
