Mode state change-over circuit 2 is connected between power supply processing circuit 1 and the microcontroller 4, is used for sending switching signal to the state detection module 42 of microcontroller 4.
The particular circuit configurations of mode state change-over circuit can be referring to Fig. 2, and Fig. 2 is the comparatively electrical schematic diagram of simple embodiment of one of LED light-emitting device of the present invention.Among Fig. 2, import by DC+ terminal and DC-terminal through the direct current after power supply processing circuit 1 processing.The mode state change-over circuit 2 of present embodiment is a power-fail detection circuit, is made up of triode Q1, diode D1, resistance R 1, R2, is used to detect the whether power down of LED light-emitting device.During operate as normal, DC+ terminal and DC-terminal are powered to power-fail detection circuit, triode Q1 conducting, and to the single-chip microcomputer U1 output low level signal as microcontroller 4.During the power down of LED light-emitting device, DC+ and DC-terminal stop to provide dc signal, because the buffer action of diode D1, triode Q1 ends, and to single-chip microcomputer U1 output high level signal, single-chip microcomputer U1 can be known the power down of LED light-emitting device.
Review Fig. 1, the LED light-emitting device also is provided with parameter detecting circuit 3, is used to detect the parameter value of setting, and detected parameter value is sent in the microcontroller 4.Referring to Fig. 2, in the present embodiment, parameter detecting circuit 3 is a RC circuit, is made up of resistance R 5 and capacitor C 2.During detection, the parameter detection module 43 of microcontroller 4 detects the capacitance of capacitor C 2 or the resistance value of resistance R 5, and detected capacitance or resistance value are sent to single-chip microcomputer U1 as parameter value.
Certainly, the light intensity testing circuit that parameter detecting circuit 3 can also use light-sensitive element to form, the perhaps temperature sensing circuit of forming by temperature-sensitive element etc., or use the combination of these circuit.Identical, adopt foregoing circuit as the parameter detecting circuit, the ambient temperature value that corresponding setup parameter is then gathered for the environmental light brightness value and the temperature-sensitive element of light-sensitive element collection.And parameter detecting circuit 3 can also be a voltage detecting circuit, and the instantaneous voltage value of the ac signal that detection power supply processing module 1 receives is as parameter value, and these change does not influence enforcement of the present invention.
The switching signal that the state detection module 42 receiving mode state switching circuits 2 of microcontroller 4 send, and the state switching signal is sent to processing module 41 and parameter detection module 43.In the present embodiment, mode state change-over circuit 2 is a power-fail detection circuit, when the power-fail detection circuit power down, to single-chip microcomputer U1 output high level signal, just sends power-off signal to state detection module 42.After treating that the LED light-emitting device powers on once more, power-fail detection circuit promptly to single-chip microcomputer U1 output low level signal, just sends power on signal to state detection module 42, and state detection module 42 promptly sends signal to processing module 41, changes current light-emitting mode state.
Parameter detection module 43 receives the parameter value that parameter detecting circuit 3 transmits, and also can detect the parameter value of setting, for example the parameter value of detected state modular converter 42 transmission.State switching circuit 42 judges that the LED light-emitting device of power-fail detection circuit detection is in the time from the power-down state to the power-up state, the pulse signal number that microcontroller 4 oscillating circuits produce, and number of pulse signals is sent to parameter detecting circuit 43 as parameter value.The oscillating circuit of microcontroller 4 can be crystal oscillator or the oscillating circuit be made up of the RLC device etc., and oscillating circuit produces the pulse signal for microcontroller 4 uses.Because the cycle of pulse signal reaches the microsecond level, and the time of LED light-emitting device from the power-down state to the power-up state needs several seconds time usually, and therefore, it is a random value that each parameter detection module 43 detects number of pulse signals.
Behind the parameter value of parameter detection module 43 detected parameters, parameter value is sent to random function 44, random function 44 application parameter values are calculated random value, and random value is sent to processing module 41.
In the present embodiment, drive circuit 5 can drive 61,62,63, three groups of LED lamp groups of three groups of LED lamp groups can be arbitrary group luminous, also can be wherein two groups luminous, or three groups all luminous.
Certainly, processing module 41 also can be judged which state the LED light-emitting device is operated in, thereby need be determined the LED lamp group of driving according to the signal of state detection module 42 transmission.
It is luminous to illustrate below in conjunction with Fig. 3 to Fig. 5 how microcontroller drives three groups of LED lamp groups.Referring to Fig. 3, be the flow chart of the luminescent method embodiment of LED light-emitting device of the present invention.After the LED light-emitting device powers on, execution in step S1 at first, it is luminous that microcontroller drives three groups of LED lamp groups by drive circuit.In the present embodiment, three groups of LED lamp groups are respectively to send redness, blueness and green LED lamp group, and three groups of LED lamp groups are simultaneously luminous, and then the LED light-emitting device sends the light of white color.
Certainly, among the step S1, microcontroller can drive also that wherein one group of LED lamp group is luminous, drives perhaps that wherein two groups of LED lamp groups are luminous, and this can corresponding program realizes in the processing module by revising.
Then, whether the state detection module judgment model state switching circuit of microcontroller sends switching signal, then enters in the corresponding light-emitting mode according to different switching signals in this way.In the present embodiment, the mode state change-over circuit is a power-fail detection circuit, and it is by sending the switching signal that power-off signal and power on signal realize sending.
Therefore, among the present embodiment step S2, processing module judges whether state detection module receives power-fail detection circuit and send power-off signal, if receive power-off signal, then calls time delay subroutine, calculates delay time, i.e. execution in step S3.
Then, microcontroller execution in step S4, state detection module judge whether power-fail detection circuit sent power on signal in 2 seconds, in this way, state detection module sends signal to processing module, and processing module is execution in step S5, enter the operation of first light-emitting mode.If the LED light-emitting device did not power in 2 seconds, then state detection circuit judges further whether the detection of power loss module sent power on signal in 4 seconds, and in this way, processing module enters the operation of second light-emitting mode, otherwise the LED light-emitting device resets, and waits for powering on once more.
This shows, state detection module sends the light-emitting mode that power-off signal and power on signal whether needing to realize the conversion LED light-emitting device by judging power-fail detection circuit, and state detection module judges to enter which light-emitting mode by judging the time between power-off signal and the power on signal.
The LED light-emitting device enter behind first light-emitting mode workflow diagram as shown in Figure 4.After entering first light-emitting mode, parameter detection module is execution in step S11 at first, detect the parameter value of setup parameter, this setup parameter can be that power-fail detection circuit sends the pulse signal number that the microcontroller oscillating circuit produces between power-off signal and the power on signal, or the capacitance of RC circuit or magnitude of voltage, also can be the detected temperature value of temperature sensing circuit, the detected environmental light brightness value of light intensity testing circuit etc.
Then, parameter detection module is sent to random function with detected parameter value, and random function execution in step S12 uses the parameter value that receives and generates a random value, and random value is sent to processing module.It is luminous that processing module determines according to random value where the needs driving organizes LED lamp group, and send control signal to driver module.
After driver module received control signal, execution in step S13 sent the driving signal to drive circuit, and it is luminous that drive circuit promptly drives corresponding LED lamp group.At this moment, a group of may drive in three groups of LED lamp groups of drive circuit is luminous, and it is luminous perhaps to drive two groups of LED lamp groups, and promptly the color that emits beam of LED light-emitting device is determined by the random value that random function generates.Because the random value that random function generates has uncertainty, therefore, each LED light-emitting device color that emits beam is not quite similar, and this glow color is at random.
After processing module driving LED lamp group is luminous, set delay time, allow drive luminous LED lamp group and in delay time, continue luminous.Delay time can be set according to actual conditions, is 4 seconds in the present embodiment.Certainly, delay time can be longer or shorter, and this does not influence enforcement of the present invention.
After delay time is set, processing module execution in step S14, judge the whether power down of LED light-emitting device, if power down then execution in step S15, if there is not power down, execution in step S16 then, judge whether delay time arrives, if delay time arrives, execution in step S18 then, it is luminous that processing module built-up sequence according to the rules drives the LED lamp group of next combination, and the LED lamp group of next combination is promptly luminous, the light color sent of LED light-emitting device can be rotated conversion according to a definite sequence like this, as according to change color such as red, yellow, purple, blue, green.Certainly, processing module drives the LED lamp group of each combination when luminous, and time-delay all is set, and in the delay time, has driven luminous LED light-emitting device and has continued luminously, and returns execution in step S14, and microcontroller continues to judge the whether power down of LED lamp group.
Among the step S16,, then return execution in step S14, continue to judge the whether power down of LED light-emitting device if delay time is less than.
Among the step S15, processing module judges whether the LED light-emitting device powers on once more, if power on, and execution in step S17 then, it is luminous to drive the LED lamp group that is driven before the power down, otherwise, continue to wait for that the LED light-emitting device powers on.Like this, after powering on once more, the LED light-emitting device promptly continues to send the color of the preceding emitted light of power down, the user sends the power supply of closing the LED light-emitting device when being fit to color light at the LED light-emitting device, after starting the LED light-emitting device once more, the LED light-emitting device promptly sends the light of the preceding color of power down, makes things convenient for the user to use.
The flow chart of second light-emitting mode as shown in Figure 5.After the LED light-emitting device enters second light-emitting mode, parameter detection module detects the parameter value of setup parameter, and parameter value is sent to random function, random function is used this parameter value and is generated random value, and random value is sent to processing module, execution in step S21 just, these are identical with first light-emitting mode, do not repeat them here.
Then, microcontroller execution in step S22, according to the rules built-up sequence is luminous by turns fast in the regular hour by drive circuit driving LED lamp group, makes the LED light-emitting device send the light of different colours fast in this time period, the effect of fast blink occurs.
Then, microcontroller execution in step S23 determine that according to random value needs drive luminous LED lamp group, and it is luminous to drive corresponding LED lamp group by drive circuit.Then, microcontroller execution in step S24, judge the whether power down of LED light-emitting device, if power down, then execution in step S25, further judge whether the LED light-emitting device powers on, after powering on, microcontroller execution in step S26, it is luminous to drive three groups of LED lamp groups, at this moment, the LED light-emitting device sends the light of white.
This shows that after microcontroller judged that the LED light-emitting device needs the conversion luminescence pattern, promptly the application parameter testing circuit detected the parameter value of setting, and should generate random value by parameter value, and determine that according to random value needs drive luminous LED lamp group by random function.This shows that the parameter value in this enforcement comprises LED light-emitting device oscillating circuit produces in the time from power-down state to power-up state pulse signal number, the capacitance the RC circuit or resistance value etc., these parameters all have certain randomness.And, the random value that random function is used these parameters generations has more randomness, therefore, and after the LED light-emitting device enters first light-emitting mode and second light-emitting mode, the color of light-emitting line is at random, satisfies people and uses the needs of LED light-emitting device as decorative light.
Certainly, LED light-emitting device of the present invention can also for example use in the recreation as a shot as uses such as amusements, the light of the different colours that application LED light-emitting device sends at every turn, as a shot You Xi conjecture object.
Simultaneously, three groups of lamp groups that LED lamp group differs and is decided to be polychrome in the LED light-emitting device of the present invention also can be monochromatic lamp groups, for example are the LED lamp group of white.Like this, when wherein one group or two groups of LED lamp groups were luminous, the LED light-emitting device sent darker light, and when three groups of LED lamp groups were all luminous, the LED light-emitting device sent brighter light.Like this, when the user needs the LED light-emitting device to send darker light, microcontroller is used the definite LED lamp group that is driven of random function, rather than fixing a certain group of LED lamp of driving group, make three groups of driven probability of LED lamp group equate, can not making wherein, one group of LED lamp group causes the LED light-emitting device can not use at the state that sends than the half-light line because of light decay appears in long-term the use.
In addition, the present invention also can be applicable in the light fixture with a plurality of LED light-emitting devices, like this, user's turn on lights has, different LED light-emitting devices can send the light of different colours, and the color that each LED light-emitting device emits beam determines at random that all person more convenient to use uses this light fixture as the use of decorating or conjecture is played.
Certainly, the foregoing description only is one embodiment of the invention, in the practical application of the present invention more change can also be arranged, for example use infrared signal receiver as the mode state change-over circuit, the infrared signal that the application remoting device sends is as the state switching signal; After perhaps the LED light-emitting device powered on first, microcontroller was not that to drive three groups of LED lamp groups luminous, but it is luminous etc. to drive wherein two groups or one group, and these change does not influence enforcement of the present invention.
At last; it is emphasized that; the invention is not restricted to above-mentioned embodiment, also should be included in protection scope of the present invention such as the change of the parameter of the change of the change of LED lamp group quantity, delay time length, parameter detecting electric circuit inspection, the minor variations such as change of random function.
