An embodiment of the utility model provides a lighting device circuit. Some embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a lighting device circuit according to an embodiment of the present invention. As shown in fig. 1, the lighting device circuit comprises a power circuit 10, a light emitting control circuit 20 and a light emitting component 30, wherein the power circuit 10 further comprises a dry battery circuit 101 and a lithium battery circuit 102.
Wherein, the dry battery circuit 101 and the lithium battery circuit 102 are connected in parallel; the light-emitting control circuit 20 is connected to the power circuit 10, and is configured to control a working state of the power circuit 10 to adjust an output current of the power circuit 10; the light emitting element 30 is connected to the power circuit 10, and emits light according to the output current of the power circuit 10.
Illustratively, the operation status of the power circuit 10 includes the dry cell circuit 101 alone powering the light emitting assembly 30, the lithium battery circuit 102 alone powering the light emitting assembly 30, or both the dry cell circuit 101 and the lithium battery circuit 102 jointly powering the light emitting assembly 30.

Illustratively, the on/off of the dry battery circuit 101 and the lithium battery 102 can be controlled by a switch.
In some embodiments, the light control circuit 20 adjusts the output current of the power circuit 10 to cause the light emitting elements 30 to emit light of different intensities.
Illustratively, the different intensities of light may include high, medium, low, and ultra low light.
By controlling the on/off of the dry battery circuit 101 and the lithium battery 102, the power circuit 10 can be selected to operate properly to provide power under the different light-emitting intensity requirements of the light-emitting component 30, so as to exert the maximum working characteristics of the power circuit 10 and prolong the light-emitting time of the light-emitting component 30.
Referring to fig. 2, fig. 2 is a schematic structural diagram of another lighting device circuit according to an embodiment of the present invention.
As shown in fig. 2, the light-emitting control circuit 20 includes a light brightness detection circuit 201, and the light brightness detection circuit 201 is connected to the power circuit 10 and the light-emitting component 30 for adjusting the output current of the power circuit 10 according to the light intensity of the environment.

In some embodiments, the light sensing element may be a photoresistor and/or a photocell.

For example, the light threshold is set to 10lux, and the photo resistor detects that the intensity of the ambient light is lower than 10lux, the output current of the power circuit 10 is increased to make the light emitting element 30 emit light.
When the light-sensitive resistor detects that the intensity of the ambient light is higher than 10lux, the output current of the power supply current 10 is reduced, so that the light-emitting intensity of the light-emitting component 30 is reduced or extinguished.
Referring to fig. 3, fig. 3 is a schematic structural diagram of another lighting device circuit according to an embodiment of the present invention.
As shown in fig. 3, the light emission control circuit 20 includes: the infrared sensing circuit 202, the infrared sensing circuit 202 is connected to the power circuit 10 and the light emitting component 30, and is used for adjusting the output current of the power circuit 10 according to the infrared sensing.

Referring to fig. 4, fig. 4 is a schematic structural diagram of another lighting device circuit according to an embodiment of the present invention.
As shown in fig. 4, the lighting control circuit 20 further includes a detection circuit 203, and the detection circuit 203 is configured to detect the voltage of the battery circuit 101 and/or the lithium battery circuit 102, and control the battery circuit 101 and the lithium battery circuit 102 to operate together based on the detected voltage.
It will be appreciated that the detection circuit 203 is also configured to detect the current of the battery circuit 101 and/or the lithium battery circuit 102, and to control the battery circuit 101 and the lithium battery circuit 102 to operate in conjunction with each other based on the detected current.
Illustratively, the control of the co-operation based on the detection of the voltage and/or current variations of the dry cell circuit 101 and/or the lithium battery circuit 102 can fully exploit the characteristics of the dry cell and increase the light emission time of the light emitting module 30.
For example, when the dry cell circuit 101 is operated alone, the light emitting module 30 can emit light with high intensity and the light intensity does not change in a short time.
For example, when the lithium battery circuit 102 is operated alone, the light emitting module 30 does not have the same light emitting intensity as that of the dry battery circuit 101 in the same light emitting mode, such as a high luminance, but the light emitting module 30 may not have the light emitting intensity changed for a long time.
In some embodiments, when the dry cell battery circuit 101 operates alone, the detection circuit 203 detects that the voltage of the dry cell battery circuit 101 starts to drop, and controls the lithium battery circuit 102 to start to operate.
Referring to fig. 5a, fig. 5a is a graph showing the luminous flux of the lighting device 40 in a high brightness state with time when the dry cell circuit 101 is operated, and it can be understood that the luminous flux begins to decrease in a short time, i.e. the dry cell circuit 101 cannot provide enough current to maintain the brightness intensity of the light-emitting component 30.
For example, a voltage threshold corresponding to the brightness intensity may be set, and if the voltage detection circuit 203 detects that the voltage of the dry battery circuit 101 drops below the voltage threshold, the lithium battery circuit 102 is controlled to start operating.
In some embodiments, when the dry cell battery circuit 101 is operated alone, the detection circuit 203 detects that the voltage of the dry cell battery circuit 101 starts to drop, controls the dry cell battery circuit 101 to stop operating, and controls the lithium battery circuit 102 to start operating.
Illustratively, the voltage of the dry cell circuit 101 begins to drop, i.e., the power of the dry cell is insufficient to support the light emitting assembly 30 to maintain the current light emitting intensity, and the current light emitting intensity is maintained through the operation of the lithium battery circuit 102 in order to maintain the light emitting intensity.
Referring to fig. 5b, fig. 5b is a graph of the luminous flux of the lighting device 40 in the highlight state when the lithium battery circuit 102 is operated, and it can be understood that the luminous intensity of the light-emitting component 30 can be maintained for a long time under the operation condition of the lithium battery circuit 102, and when the output current of the dry battery circuit 101 is not enough to maintain the luminous intensity of the light-emitting component 30, the operation is switched to the lithium battery circuit 102, so that the output current of the lithium battery circuit 102 keeps the light-emitting component 30 emitting light.
In some embodiments, when the dry cell battery circuit 101 operates alone, the voltage detection circuit 203 detects that the voltage of the dry cell battery circuit 101 starts to drop, and controls the lithium battery circuit 102 to operate, so that the dry cell battery circuit 101 and the lithium battery circuit 102 operate together.
Referring to fig. 5c, fig. 5c is a graph showing the change of the luminous flux of the lighting device 40 with time in a high-light state when the dry battery circuit 101 and the lithium battery circuit 102 work together, and it can be understood that the light emitting time of the light emitting module 30 is greatly prolonged when the dry battery circuit 101 and the lithium battery circuit 102 work together.
In one embodiment, when the dry battery circuit 101 operates alone, the detection circuit 203 controls the lithium battery circuit 102 to start operating when detecting that the dry battery circuit 101 is lower than a preset current threshold.
Illustratively, the lithium battery circuit 102 may be controlled to start operating and the dry battery circuit 101 may be controlled to stop operating, or the lithium battery circuit 102 may be controlled to operate in conjunction with the dry battery circuit 101.
For example, the detection circuit 203 detects that the dry battery circuit 101 is lower than a preset current threshold, that is, the dry battery circuit 101 cannot maintain the current light intensity of the light emitting assembly 30, and the current light intensity of the light emitting assembly 30 is maintained through the operation intervention of the lithium battery circuit 102.
In one embodiment, when the lithium battery circuit 102 operates alone and the detection circuit 203 detects a decrease in voltage and/or current of the lithium battery circuit 102, the dry battery circuit 101 is controlled to start operating.
Illustratively, when the lithium battery circuit 102 is operated for a period of time until the power is insufficient, the voltage and/or current will decrease, so that the light-emitting brightness of the light-emitting component 30 will decrease, and the dry battery 101 will be controlled to operate.
Illustratively, the dry cell battery circuit 101 may be controlled to start operating and the lithium battery circuit 102 may stop operating, or the dry cell battery circuit 101 may be controlled to operate in conjunction with the lithium battery circuit 102.
Referring to fig. 6, fig. 6 is a graph showing circuit current when the dry battery circuit 101 and the lithium battery circuit 102 work together, and as shown in fig. 6, a plurality of battery circuits 101 work together with the lithium battery circuit 102 to enhance the discharge time of the dry batteries in the dry battery circuit 101, thereby obtaining a longer endurance time.
Specifically, as shown in fig. 7, fig. 7 is a schematic diagram of the discharge current and the battery capacity distribution of the unit cells, and the smaller the discharge current of some of the batteries is, the larger the capacity of the unit cells is.
Illustratively, when the dry cell circuit 101 and the lithium battery circuit 102 work together, the dry cell circuit 101 and the lithium battery circuit 102 provide discharge current together, and in this case, the discharge current provided by the dry cell circuit 101 is smaller than the current provided when the dry cell circuit 101 works alone, the capacity of the dry cell in the circuit is larger, and the longer the discharge time is obtained.
Illustratively, the more sufficient the lithium battery in the lithium battery circuit 102, the greater the discharge current that can be provided, and the less the discharge current that can be provided by the dry cells in the dry cell circuit 101, the greater the capacity of the dry cell and the longer the discharge time that can be obtained.
For example, the discharge current of the dry battery circuit 101 and the lithium battery circuit 102 may be controlled by a current control knob to increase the discharge time.
Illustratively, by the operation of the dry cell circuit 101 and the lithium battery 102, the characteristics of the dry cell in the dry cell circuit 101, i.e. the discharge time, can be maximized, the service life of the battery can be prolonged, and the frequent replacement of the battery by a user can be avoided.
The lighting device circuit provided by the above embodiment comprises a power circuit 10, a light-emitting control circuit 20 and a light-emitting component 30, wherein the power circuit 10 further comprises a dry battery circuit 101 and a lithium battery circuit 102; the working state of the power supply circuit 10 is controlled by the light-emitting control circuit 20, that is, the dry battery circuit 101 works alone, the lithium battery circuit 102 works alone or the dry battery circuit 101 and the lithium battery circuit 102 work together, so that the output current of the power supply circuit 10 is adjusted to match the requirements of the light-emitting component 30 in different light-emitting modes, the power supply characteristics of the dry battery and the lithium battery are fully exerted, and the light-emitting time of the light-emitting component 30 is greatly increased.
