Description

Technical Field

[0001] The present invention relates to the technical field of smart lamps, and in particular to a lamp charging method and device. Background Art

[0002] Currently, some low-power lighting products (such as nightlights and cool lights) are charged through integrated circuits. The charging current is determined by the size of the IC's external resistors, meaning the charging current is fixed. Whether these products are charged via an adapter or a Universal Serial Bus (USB) interface, the charging current remains fixed while in use. However, with a fixed external power input (such as USB 5V / 1A), these solutions must simultaneously charge the battery and power the light source circuit. The combined power cannot exceed 5V / 1A. Circuit design forces either sacrificing LED output power to maintain charging time, or reducing charging time to maintain power to the light source circuit. This compromise is not possible, resulting in reduced charging flexibility and significant battery loss.

[0030] In an embodiment of the present invention, the current display state of the lamp is obtained; it is determined whether the above-mentioned current display state is the lighting state; if the above-mentioned current display state is the lighting state, a first pulse signal corresponding to the above-mentioned lighting state is determined, wherein the duty cycle of the first pulse signal is used to determine the charging current corresponding to the rechargeable battery in the above-mentioned lamp; the charging of the above-mentioned rechargeable battery is controlled according to the above-mentioned first pulse signal, thereby achieving the purpose of obtaining the corresponding pulse signal according to the lighting state of the lamp and dynamically adjusting the charging current of the battery through the pulse signal, thereby achieving the technical effect of improving the charging efficiency of the lamp battery, reducing battery loss, and realizing flexible charging, thereby solving the technical problem of low charging flexibility and large battery loss caused by using a fixed current value to charge the battery in the lamp when the lamp is used and charged in the prior art.

[0031] Optionally, the above-mentioned current display state includes a lighting state and an off state, and different current display states correspond to different charging methods. For example, when the above-mentioned current display state is the off state, a predetermined current signal is used to charge the above-mentioned rechargeable battery. The above-mentioned predetermined current signal may be, but is not limited to: all the voltages that the external power supply can provide are output to the rechargeable battery, and the external power supply is used to directly charge the above-mentioned rechargeable battery. This achieves dynamic improvement of charging efficiency when the light is not on. When the above-mentioned current display state is the above-mentioned lighting state, the first pulse signal corresponding to the lamp in the lighting state is obtained, and the charging current corresponding to the rechargeable battery in the above-mentioned lamp is determined according to the duty cycle of the above-mentioned first pulse signal, and the above-mentioned rechargeable battery is charged using the charging current. In this way, the purpose of dynamically charging the rechargeable battery is achieved, while improving the charging efficiency, reducing the loss of the rechargeable battery, and increasing the service life of the rechargeable battery.

[0032] Optionally, the lighting state includes multiple different lighting states, which may be light brightness, light hue, etc. For example, warm light hue, cool light hue, strong light brightness, weak light brightness, etc. The first pulse signal is determined by the lighting state of the lamp, and under different lighting states, the first pulse signal corresponds to different duty cycles.

[0038] Optionally, the target resistance value is used to determine the first current signal corresponding to the rechargeable battery, that is, the charging current corresponding to the rechargeable battery is controlled by regulating the resistance corresponding to the rechargeable battery through the first pulse signal.

[0039] In an optional embodiment, the lamp includes: a resistance circuit corresponding to the rechargeable battery, the resistance circuit including a first resistance branch and a second resistance branch, the first resistance branch and the second resistance branch being connected in parallel, and determining the target resistance value corresponding to the rechargeable battery based on the first pulse signal includes:

[0043] Optionally, the resistance circuit corresponding to the above-mentioned rechargeable battery is a variable resistance circuit. It includes a first resistance branch with a variable resistance value, and a second resistance branch with a fixed resistance value. The above-mentioned first resistance branch with a variable resistance value can be, but is not limited to, composed of a transistor and a variable resistor. The current conduction state of the transistor is controlled by a first pulse signal. The different duty cycles of the first pulse signal cause the current conduction state of the transistor to change, and the target resistance value corresponding to the resistance circuit changes accordingly, thereby realizing dynamic adjustment of the current signal of the rechargeable battery (i.e., the above-mentioned first current signal).

[0047] Optionally, the current conduction state of the transistor includes: a fully-on state, a fully-off state, and a partially-on state. The current conduction state of the transistor is determined by the duty cycle of the first pulse signal. When the duty cycle of the first pulse signal changes, the current conduction state of the transistor changes, and the first resistance value corresponding to the first resistance branch changes accordingly. Figure 2FIG. 1 shows a schematic diagram of a circuit structure of an optional cool lamp according to an embodiment of the present invention, as shown in FIG. Figure 2 As shown in FIG, a schematic diagram of a resistor circuit is shown, in which the first resistor branch is composed of a transistor Q4 and a first resistor R19.

At this time, the target resistance value reaches a minimum, the charging current corresponding to the rechargeable battery is the largest, the charging current is dynamically increased, and the charging efficiency is improved.

[0049] Optionally, when the current display state of the lamp is the lit state, and the light brightness corresponding to the lit state reaches maximum, the duty cycle of the first pulse signal reaches maximum. At this time, the current on-state of the transistor reaches a fully off state, the second resistance value is the target resistance value, the target resistance value reaches maximum, and the charging current corresponding to the rechargeable battery reaches minimum. In an optional embodiment, when the lamp includes multiple light source circuits, determining the first pulse signal corresponding to the lit state includes:

[0050] Obtaining second pulse signals corresponding to the plurality of light source circuits respectively, wherein the second pulse signals correspond to the lighting states of the plurality of light source circuits;

[0051] The second pulse signals corresponding to the plurality of light source circuits are processed to obtain the first pulse signal.

[0052] Optionally, when the lamp includes multiple light source circuits, the first pulse signal is obtained by performing logical processing on the second pulse signal. For example, the multiple second pulse signals are sent to a microcontroller circuit, which performs certain logical processing on the multiple second pulse signals to obtain the first pulse signal.

[0053] As an optional embodiment, Figure 2 and Figure 3 FIG. 1 is a schematic diagram of a circuit structure of an optional cool lamp according to an embodiment of the present invention. Figure 2 and Figure 3As shown, the cool lamp includes two light source circuits, and the circuit structure mainly includes: a rechargeable battery, a microcontroller, a first light source circuit, a first pulse circuit corresponding to the first light source circuit, a second light source circuit, a second pulse circuit corresponding to the second light source circuit, an external power supply circuit, a rechargeable battery, and a resistance circuit; wherein the above-mentioned resistance circuit includes a first resistance branch composed of a transistor Q4 and a first resistor R19 connected in series, and a second resistance branch composed of a second resistor R4, and the first resistance branch and the second resistance branch are connected in parallel; the above-mentioned resistance circuit, the above-mentioned first pulse circuit and the above-mentioned second pulse circuit are all connected to the above-mentioned microcontroller circuit through different interfaces, and the above-mentioned is also connected to the rechargeable battery, the above-mentioned first light source circuit is connected to the above-mentioned first pulse circuit, and the above-mentioned second light source circuit is connected to the above-mentioned second pulse circuit, and the above-mentioned external power supply circuit charges the lamp via the serial bus interface (Universal Serial Bus, USB) of the external adapter.

[0054] When the current display state of the lamp is the lighting state, and the lighting state corresponding to the lighting state is the light brightness, the first control signal emitted by button TP1 is used to control the first light source circuit to be turned on, corresponding to the first light brightness. At this time, the first pulse pin W-PWM corresponding to the first pulse circuit emits a high level, and the second pulse pin Y-PWM corresponding to the second pulse circuit emits a low level; the second control signal emitted by button TP2 is used to control the second light source circuit to be turned on, corresponding to the second light brightness, wherein the second light brightness is greater than the first light brightness. At this time, the first pulse pin W-PWM emits a low level, and the second pulse pin Y-PWM emits a high level; the third control signal emitted by button TP3 is used to control the first light source circuit and the second light source circuit to be turned on at the same time, corresponding to the third light brightness, that is, button TP3 corresponds to the maximum light brightness, and the first pulse pin W-PWM and the second pulse pin Y-PWM both emit high levels.

[0055] It should be noted that different light brightnesses correspond to different first pulse signals, i.e., different duty cycles of the first pulse signals are obtained. When the current display state of the lamp is the lit state, at least one of the two pins W-PWM or Y-PWM is at a high level, and at least one of the corresponding switches Q2 and Q3 is turned on. When both the W-PWM or Y-PWM pins are at a high level, that is, when both switches Q2 and Q3 are turned on, the microcontroller circuit (such as a single-chip microcomputer) determines through internal logic that the ISET pin does not output a signal, and the transistor Q4 does not turn on. At this time, the size of the charging current corresponding to the rechargeable battery is only determined by the second resistor R4, and a low current charging can be set.

[0056] When the current display state of the lamp is off, the above-mentioned rechargeable battery is charged, and the above-mentioned first pulse pin W-PWM and the above-mentioned second pulse pin Y-PWM must all output low levels. The micro-control circuit obtains the first pulse signal through internal logic judgment, so that the transistor Q4 is turned on. At this time, the size of the charging current corresponding to the rechargeable battery depends on the result of the second resistor R4 and the first resistor R19 being connected in parallel. That is, at this time, the charging current corresponding to the rechargeable battery dynamically reaches the maximum and the charging efficiency is the highest.

[0057] The embodiments of the present invention can at least achieve the following technical effects: (1) When the lamp is used while being charged, the charging current corresponding to the rechargeable battery is reduced, and the limited input power is mostly distributed to the light source circuit, with a small amount used for charging, which not only increases the output power but also extends the battery life; when charging is not in use, the system automatically determines internally to improve the charging efficiency, and when the limited input power is small, all of it is used for charging to meet the fast charging requirements.
