Description

Technical Field

[0001] The present invention relates to the technical field of lamps and wiring, and in particular to a quick-connect lamp, a driving device and a system. Background Art

[0002] At present, domestic and commercial LED lamps are basically equipped with a built-in or external driver power supply, which converts AC mains power into DC power and provides constant voltage or constant current to drive the normal operation of the lamp. In practical applications, such lamps require that the mains power wires must be laid to the installation location of the lamp and connected to the driver power supply. The installation and wiring are relatively complicated and require professional electrician skills and tools. This not only increases the difficulty of installation, but also increases the construction time and cost. Especially in some Western countries, the cost of hiring professional electricians is high.

[0003] In addition, each traditional LED lamp is equipped with a separate driver, which increases the complexity and cost of the system. The driver occupies a considerable volume and weight, making the transportation and packaging costs of the lamps high.

[0004] The installation of smart lamps is becoming more and more popular, such as Wi-Fi lamps, Bluetooth lamps, Zigbee lamps, and Matter lamps. The current mainstream technical solution is that a lamp needs to be equipped with a smart module, which is equivalent to a lamp being a smart device. A room often needs to install several lamps, and a family needs to install more lamps. This brings two problems: First, the cost of smart modules is relatively high, accounting for almost 50% of the total cost of smart lamps in low-power household lamps. Second, as the number of smart lamps installed increases, the number of devices that can be supported by smart gateways (such as home Wi-Fi routers) is limited, and additional routers need to be added, which can easily cause network delays, data loss, and unstable lamp network connections.

[0005] Therefore, there is an urgent need for a lamp whose installation and wiring can be as safe and simple as connecting a computer to the Internet with twisted pair cables, which can reduce the difficulty of installation and wiring, reduce the workload of wiring, and thus reduce installation costs; there is an urgent need for a lamp that can save the driving power supply of each lamp, thereby reducing the size and weight of the entire lamp, thereby reducing shipping and material costs; there is an urgent need for a lamp that can greatly reduce the use of intelligent modules, reduce the cost of intelligent lamps, and reduce the load on the intelligent network. Summary of the invention

[0006] The object of the present invention is to provide a quick-connect lamp, a driving device and a system to address the deficiencies of the prior art.

[0007] The present invention achieves the above-mentioned purpose through the following technical scheme: a quick-connect lamp is invented, which has at least one external port inserted by one end of a twisted pair cable, and the external port is a twisted pair connector, which is used to obtain the power required for the operation of the lamp and / or obtain the control signal required for the operation of the lamp and / or send a response signal.

[0008] A further solution of the present invention: when the number of the twisted pair connectors is not less than 2, any one of the twisted pair connectors is used to obtain power and / or control signals, and the remaining twisted pair connectors are used to cascade power and / or control signals between the lamps.

[0009] A quick-connect drive device is invented for driving the quick-connect lamp described above, wherein the quick-connect drive device has at least one connection port into which one end of a twisted pair cable is inserted, and the connection port is a twisted pair connector or a twisted pair hub, and is used to output the power required for the lamp to operate and / or the control signal required for the lamp to operate and / or input a response signal issued by the lamp.

[0010] Invented a quick-connect lighting system comprising:

[0011] Twisted pair, used to transmit power or power and control signals;

[0012] A quick-connect lamp having at least one twisted pair connector connected to one end of the twisted pair for obtaining power and / or obtaining power and control signals from the twisted pair; and

[0013] A quick-connect drive device, the output end of which includes at least one twisted pair connector or twisted pair hub connected to the other end of the twisted pair, for generating power and / or control signals required for the operation of the lamp;

[0014] Wherein, the quick connection driving device is the quick connection driving device described above; the quick connection lamp is the quick connection lamp described above.

[0015] Beneficial effects of the present invention:

[0016] 1. Reduce the difficulty of installation and wiring, so that ordinary users without electrical knowledge can complete most of the installation work.

[0017] In traditional LED lighting systems, each lamp needs to have high-voltage mains wires laid to the installation holes of each lamp and connected to the driving power supply of each lamp, which means that all installation work requires professional electricians or users who know electricians to complete. However, this solution uses twisted pair cables to transmit power and control signals, making the wiring of lamps safer and simpler. Most of the connection work can be completed without electrician knowledge.

[0018] 2. Reduced packaging and transportation costs.

[0019] In traditional lamps, the driving power supply often occupies half of the volume and weight. The quick-connect lamp of the present invention saves the separate power supply for each lamp and instead all the lamps in the system share one power supply, which greatly saves the volume and weight of the lamp, thereby reducing the cost of packaging materials and transportation costs.

[0020] 3. Reduce the cost of smart lamps.

[0021] The current technical solution for smart lamps is basically one smart module for one lamp, and the cost of the smart module accounts for a large part of the cost of the entire smart lamp, resulting in the price of smart lamps being much higher than that of non-smart lamps, which to a certain extent hinders the popularization of smart lamps. The present invention allows only one smart module to control all lamps in the system, greatly reducing the cost of smart lamps and facilitating the popularization of smart lamps.

[0022] 4. Reduced the networking pressure of smart lamps.

[0023] Traditional smart lamps are equipped with an intelligent module, and each lamp is a smart device. Economical routers usually have only a dozen device ports. Mobile phones, computers and other devices at home have already occupied several of them. The remaining device ports are not enough to drive all the smart lamps in the home. Usually, more routers are needed to expand the capacity according to the number of lamps installed, which is prone to cause device disconnection, response delays and other phenomena. The present invention only needs one intelligent module to realize the intelligent control of multiple lamps in the system, greatly reducing the number of device ports, thereby greatly reducing the expansion pressure of the smart network and reducing the investment in network expansion.

[0024] 5. The performance of the 0-10V dimming system can be improved. As the length of the 0-10V dimming signal line increases, the 0-10V signal voltage will decrease, which will cause the brightness of the lamps at a long distance to be slightly lower than that of the lamps at a short distance. The more lamps are connected to the same 0-10V signal line and the longer the distance, the more obvious the difference will be. In the present invention, since the lamps in a system share a power supply, the length of the 0-10V signal line that controls the same number of lamps can be greatly shortened, so the problem of inconsistent signal voltage can be improved.

[0025] The performance of the switch color temperature switching system can be improved. Conventional lamps that support switch color temperature switching have one driving power supply for each lamp. Therefore, after multiple switches, some lamps often become out of sync and the light colors are inconsistent. A reset operation must be performed from time to time to resynchronize. In the present invention, since lamps in a system share one power supply, the number of power supplies is greatly reduced, and the probability of asynchrony is also greatly reduced.

[0059] The present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0060] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present invention; the terms "first", "second", and "third" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance. In addition, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal connection of two components; the terms "control signal" and "control information" have the same meaning in the description of the present invention, including both a single electrical signal and a signal code stream and an information code stream composed of multiple electrical signals. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. The terms used in the description of the present invention herein are for the purpose of describing specific embodiments only and are not intended to limit the present invention.

[0061] The present invention uses the same twisted pair cables and twisted pair connectors as telephones and computers to achieve power transmission and control signal transmission between lamps and power supplies, and between lamps. The advantage is that the wiring is very safe, simple and fast, does not require special electrical skills, and the time and labor costs of installation and wiring can be greatly saved.

[0062] Furthermore, several quick-connect lamps have been invented, the characteristics of which are:

[0063] a) There are one or more twisted pair connectors, and power and control signals are transmitted via the twisted pair. High-voltage power lines no longer need to be laid to each lamp installation location.

[0064] b) Each lamp no longer requires a separate power supply. All lamps in the system are powered by a quick-connect power supply, which greatly reduces the cost, volume, weight, packaging materials and transportation costs of the lamps.

[0065] Furthermore, quick-connect controllers have been invented. These controllers can be installed in the same power box as the power circuit, or they can be separate controllers. The output ports of these controllers are twisted pair connectors, and the controllers are equipped with an intelligent module. With this module, all lamps in the system can be intelligently controlled, and the pressure on the intelligent network can be greatly reduced, the transmission speed can be greatly improved, the network stability is higher, the response speed is faster, and the cost of intelligent lamps is greatly reduced.

[0066] Furthermore, several non-dimming quick-connect constant voltage power supplies are invented, characterized in that the output port is a twisted pair connector or a twisted pair hub, which is used for lighting systems suitable for constant voltage power supply.

[0067] Furthermore, a constant voltage power supply compatible with 0-10V dimming was invented. The characteristic is that the output port is a twisted pair connector. This power supply can output a constant voltage and output digital dimming control information according to the input 0-10V dimming signal, which can greatly improve the phenomenon of inconsistent brightness of lamps caused by 0-10V voltage drop.

[0068] Furthermore, several quick-connect power supplies including ordinary constant current power supply circuits are invented, including ordinary dimmable constant current power supplies and ordinary non-dimming constant current power supplies, characterized in that the output port is a twisted pair connector or a twisted pair hub, which is used for lighting systems suitable for constant current power supply.

[0069] Furthermore, a special fast-connect constant current power supply was invented. The output port of this power supply is a twisted pair interface. This power supply can detect how many lamps are connected to the current system, and then adjust the output current to adapt to the dynamically changing load, that is, the number of lamps in the system can be increased or decreased. This special constant current power supply is called adaptive dynamic load constant current power supply. (SADLCC power supply).

[0070] Furthermore, a SADLCC power supply compatible with a phase-cut dimmer is invented, so that the quick-connect lighting system can be compatible with the phase-cut dimmer.

[0071] Furthermore, a SADLCC power supply that supports switching color temperature and is compatible with phase-cut dimmers is invented. Due to the reduction in the number of driving power supplies used, compared with traditional switch-switched color temperature lamps, the present invention greatly reduces the problem of some lamps being out of sync with color after multiple switches and needing to be reset.

[0072] Furthermore, a SADLCC power supply that supports switch pre-selected color temperature and is compatible with phase-cut dimmers is invented, so that the quick-connect lamp system can replace the lamps with switch pre-selected color temperature currently on the market.

[0073] Furthermore, a SADLCC power supply compatible with a 0-10V dimmer is invented.

[0074] The present invention includes, but is not limited to, the following elements:

[0075] (1) The twisted pair cable mentioned in the present invention may be one pair of cores (CAT1) or two pairs of cores (CAT2).

[0076] 3 pairs of cores (CAT3) or 4 pairs of cores (CAT4, CAT5, CAT5e, CAT6, CAT6e, CAT7, CAT7e, CAT8, etc.), all of the above types of twisted pair cables are collectively referred to as 'twisted pair cables' in the present invention.

[0077] (2) The plug and socket used for the twisted pair can be RJ11, RJ12, RJ14, RJ25 or RJ45. All of the above plugs and sockets are collectively referred to as "twisted pair connectors" in the present invention. Fig.16 and Fig.17 As shown, it includes a quick-connect lamp 1a, a socket 11a, a twisted pair 2a and a plug 21a.

[0078] (3) In the present invention, lamps with one or more 'twisted pair connectors' are collectively referred to as 'quick-connect lamps'.

[0079] (4) Each lamp body has one or more 'twisted pair connectors'.

[0080] (5) In the present invention, power supplies with one or more 'twisted pair connectors', including constant voltage power supplies and constant current power supplies, are collectively referred to as 'quick connect power supplies'.

[0081] (6) In the present invention, controllers with one or more 'twisted pair connectors', including controllers with built-in power circuits and controllers with external power supplies, are collectively referred to as 'quick connect controllers'.

[0082] (7) In the present invention, the "quick connect power supply" and the "quick connect controller" are collectively referred to as

[0084] (8) The core of a twisted pair cable can be used entirely for transmitting power, or partially for transmitting power and partially for transmitting control signals.

[0085] (9) The control signal can be transmitted using TTL logic levels, COMS logic levels, open collector circuits, open drain circuits, totem pole circuits, or differential signals.

[0086] (10) The lamp body may include only one color of light, or two colors of light (such as warm white and cool white), or multiple colors of light (such as warm white + cool white + red, green and blue).

[0087] (11) The control and driving circuit of the LED light source can be arranged inside the lamp body or outside the lamp body.

[0088] like Figure 1-1 FIG. 1 is a schematic diagram of the overall structure of the quick-connect lamp system of the present invention.

[0089] The AC power input passes through a switch or dimmer 1001 and enters a quick-connect driver 1002. The output port of the quick-connect driver is a twisted pair connector 1003. The constant voltage power supply or constant current power supply, as well as the control signal, generated by the quick-connect driver are transmitted to one end of a twisted pair 1004 via the twisted pair connector 1003. The other end of the twisted pair 1004 is connected to a quick-connect lamp 1005. The quick-connect lamp 1005 has one or more twisted pair connectors. For lamps with more than two twisted pair connectors, the power supply or the power supply and the control signal are input from one of the quick connectors and output from the remaining twisted pair connectors to the next quick-connect lamp.

[0090] like Figure 1-2 FIG. 1 is a schematic diagram of the overall structure of another form of a quick-connect lamp system of the present invention.

[0091] The AC power input passes through a switch or dimmer 1001 and enters a quick-connect driver 1002. The output power or power and control signal of the quick-connect driver enters a twisted pair hub 1006. The twisted pair hub 1106 has multiple twisted pair connectors 1003. One end of the twisted pair 1004 is connected to the twisted pair connector 1003 on the hub 1106, and the other end is connected to the twisted pair connector 1003 of the quick-connect lamp 1005.

[0092] like Figure 1-3As shown, there are three types of structural schematic diagrams of the quick-connect lamp system of the present invention. The first type of quick-connect lamp system is shown by the dotted line 11. The characteristic of this type is that the quick-connect driver is a non-dimming quick-connect constant-voltage power supply. The AC power 1101 passes through a switch 1102 and enters the quick-connect driver 1103. The quick-connect driver 1103 is a non-dimming quick-connect constant-voltage power supply. The power supply converts the input AC AC power into a constant-voltage DC power, outputs it to the twisted pair connector 1104, and then transmits it to the non-dimming quick-connect lamp 1106 through the twisted pair 1105, and cascades to other non-dimming quick-connect lamps 1106 in the system through the twisted pair 1105. The second type of quick lamp connection system is shown by the dotted line 12. The characteristic of this type is that the quick-connect driver is a dimmable quick-connect constant-voltage power supply. The mains 1201 passes through a dimmer switch 1202 and enters a quick-connect driver 1203. The quick-connect driver 1203 is a dimmable quick-connect constant voltage power supply. The dimmable quick-connect constant voltage power supply converts the input AC mains into a constant voltage DC power on the one hand, and converts the dimming signal from the dimmer switch or remote control into a lamp control signal on the other hand, and outputs both the DC voltage and the lamp control signal to the twisted pair connector 1204, and then transmits them to the dimmable quick-connect lamp 1206 through the twisted pair 1205, and cascades to other dimmable quick-connect lamps 1206 in the system through the twisted pair 1205. The third type of quick lamp connection system is shown by the dotted line 13. The characteristic of this type is that the quick-connect driver is an adaptive dynamic load constant current power supply (SADLCC power supply). The AC power 1301 passes through a switch (or dimmer switch) 1302 and enters the quick-connect driver 1303. The quick-connect driver 1303 is an adaptive dynamic load constant current power supply. This power supply can automatically detect the number of lamps currently connected to the system and output a corresponding operating current. At the same time, it converts the dimming signal from the dimmer switch into a lamp control signal, and outputs the output current and the lamp control signal to the twisted pair connector 1304, and then transmits it to the dimmable quick-connect lamp 1306 through the twisted pair 1305, and cascades to other dimmable quick-connect lamps 1306 in the system through the twisted pair 1305.

[0093] like Figure 1-4As shown, the fourth type of fast lamp connection system of the present invention is characterized in that the fast connection driving device is a common constant current power supply and a twisted pair hub. The mains electricity passes through a switch or dimmer 1401 and enters a common constant current power supply 1402. The common constant current power supply 1402 can be a non-dimming constant current power supply or a dimmable constant current power supply. The current output by the common constant current power supply 1402 is sent to the twisted pair hub 1406. The twisted pair hub 1406 includes a plurality of twisted pair connectors 1403. The current is transmitted to the fast connection lamp 1405 without a driving circuit with the twisted pair connector 1403 through the twisted pair connector 1403 and the twisted pair 1404. The number of the fast connection lamps 1405 must be able to match the current output by the common constant current power supply, and the number of lamps 1405 cannot be increased or decreased after power-on, and the length of the twisted pair connecting each lamp 1405 must be equal to avoid obvious brightness differences between the lamps.

[0094] like Figure 2-1 As shown, it is a schematic diagram of the structure of three quick-connect drive devices of the present invention. The quick-connect drive device shown by the dotted line 21 is a first implementation of a non-dimming quick-connect constant voltage power supply. The input AC power 2101 enters a conventional constant voltage power supply circuit 2102, and the constant voltage is output via a twisted pair connector 2103. The twisted pair connector 2103 and the power supply circuit are encapsulated as a whole in the same housing. The quick-connect drive device shown by the dotted line 22 is a second implementation of a non-dimming quick-connect constant voltage power supply. The input AC voltage 2201 enters a conventional power supply 2202, and the constant voltage is first output via a DC connector or wire 2203, and then connected to an independent twisted pair connector 2204 externally. The dotted line 23 shows the third implementation of a non-dimming quick-connect constant voltage power supply. The input AC power 2301 enters a conventional constant voltage power supply 2302, and the constant voltage is output via a DC connector or wire 2303, and connected to an external hub 2034 with multiple twisted pair connectors.

[0095] like Figure 2-2As shown in the figure, it is a schematic diagram of the structure of two other quick connection drive devices of the present invention. As shown by the dotted line 24, the quick connection drive device is a common constant current power supply and a twisted pair connector. The mains 2401 enters a common constant current power supply circuit 2402. The common constant current power supply circuit 2402 can be a non-dimming constant current power supply circuit or a dimmable constant current power supply circuit. The constant current output by the common constant current power supply 2402 is electrically connected to one or more twisted pair connectors 2403. The twisted pair connector 2403 and the common constant current power supply circuit 2402 are encapsulated in the same housing. As shown by the dotted line 25, the quick connection drive device is a common constant current power supply and a twisted pair hub. The mains 2501 enters a common constant current power supply 2502. The common constant current power supply 2502 can be a non-dimming constant current power supply or a dimmable constant current power supply. The current output by the power supply 2502 is electrically connected to the twisted pair hub 2504 including one or more twisted pair connectors through a DC connector or wire 2503. The ordinary constant current power supply 2502 and the twisted pair hub 2504 of this implementation are independent of each other and are not in the same housing.

[0096] like Figure 3-1 As shown, it is a schematic diagram of the structure of another quick connection drive device of the present invention, and this quick connection drive device is a quick connection controller with a built-in constant voltage power supply. The quick connection controller and the constant voltage power supply circuit of this type are packaged inside the same housing. The input voltage 3101 enters the constant voltage power supply circuit 3102, and most of the output constant voltage current 3103 flows directly to the twisted pair connector 3111. A small part of the constant voltage current enters a DC-DC conversion circuit 3104. The DC-DC conversion circuit 3104 outputs a working voltage 3105 to the intelligent module 3108, or the wireless receiving or infrared receiving module 3107, or other control modules 3106, and the single-chip microcomputer 3109. The single-chip microcomputer 3109 receives the input voltage 3101 from the intelligent module 3108 or the wireless receiving or infrared receiving module 3107 or other The control module 3106 receives the first control signal, converts it into a second control signal sent to the quick-connect lamp, and sends it to the twisted pair quick connector 3111 via the control signal driving circuit 3110. The control signal driving circuit 3110 can be a TTL logic level driving circuit, a COMS level driving circuit, an open collector driving circuit, an open drain driving circuit, a totem pole driving circuit, or a differential signal driving interface circuit (such as an RS485 interface circuit).

[0097] like Figure 3-2As shown, it is a schematic diagram of the structure of another quick-connect drive device of the present invention, and this drive device is a quick-connect controller with an external constant voltage power supply. The quick-connect controller and the constant voltage power supply circuit of this type are encapsulated in two independent shells. The AC input first enters a conventional constant voltage power supply or a quick-connect constant voltage power supply 3201, and the constant voltage direct current output by the constant voltage power supply 3201 enters the controller circuit within the dotted line 32 from a DC connector or wire or twisted pair connector 3202. Most of the constant voltage current flows directly to the twisted pair connector 3209 at the output end, and a small part of the constant voltage current enters the DC-DC conversion circuit 3203. The DC-DC conversion circuit 3203 outputs a working voltage to the intelligent control module 3206, or the wireless receiving module or the infrared receiving module 3205, or other control Module 3204, and a single-chip microcomputer 3207, the single-chip microcomputer 3207 receives the first control signal from the above one or more control modules, converts it into a second control signal for controlling the light, and sends it to the twisted pair connector 3209 via the control signal driving circuit 3208. The control signal driving circuit 3208 can be a TTL logic level driving circuit, a COMS level driving circuit, a collector open circuit driving circuit, a drain open circuit driving circuit, a totem pole driving circuit, or a differential signal driving interface circuit.

In functional module 1502, the single-chip microcomputer U3 first sends a control instruction Lb to the lamp. The variable Lb represents the light brightness, which is initialized to 0. The variable Cpwm represents the duty cycle of the PWM dimming signal used to adjust the output current. Cpwm is initialized to 0 and sent to the constant current generating circuit compatible with PWM dimming and analog dimming. The control flow enters functional module 1503. In functional module 1503, the single-chip microcomputer U3 reads the dimming signal pulse width Dm of the current phase-cut dimmer and stores Dm in the variable Dmp. Assuming that the system can connect a maximum of N lamps, Dm is divided by N to obtain the proportion Dstep corresponding to each lamp. m is a counter variable initialized to N. The Dstep value is assigned to the brightness variable Lb and sent to the lamp. That is, it is assumed that there is only one lamp in the system. Then the microcontroller U3 samples the voltage signal V4 reflecting the load current and stores V4 in the variable V4p.

[0123] The control flow continues to function module 1504, the single-chip microcomputer increases the PWM duty cycle signal Cpwm for adjusting the output current by Dstep (increase the current of one lamp), and sends Cpwm to the constant current generating circuit compatible with PWM dimming and analog dimming, and at the same time, the counter m is reduced by 1, the control flow continues to function module 1505, the single-chip microcomputer U3 samples the voltage signal V4 reflecting the load current, the control flow continues to condition module 1506, if V4>V4p (the load current is increasing), it means that there are more lamps in the system, then the control flow comes to function module 1516, the new V4 value is stored in V4p, the lamp quantity counter is reduced by 1, and then the control flow comes to condition module 1517, if m is equal to 0, the output current has reached the maximum value,

[0124] The control flow jumps to function module 1508, otherwise the control flow jumps back to 1504. If the jump module 1506 is negative, it means that the output current exceeds the total working current of the lamps currently connected to the system, and the control flow jumps to function module 1507, and the output current is restored to the value of the previous cycle.

[0125] In function module 1508, microcontroller U3 samples output voltage V3 and stores the value of V3 in variable V3p. Then the control flow goes to function module 1509. Microcontroller U3 reads pulse width Dm from phase-cut dimming detection circuit and compares it with original Dm value stored in variable Dmp. Then the control flow goes to condition module 1510. If Dm is equal to Dmp, it indicates that no dimming action occurs. Then the control flow goes to function module 1511. If Dm is not equal to Dmp, it indicates that dimming action occurs. Then the control flow jumps to condition module 1518. In function module 1511, microcontroller U3 samples output voltage V3. Then the control flow goes to condition module 1518. Conditional module 1512, if the value of V3 is the same as the original value V3p, it means that the number of lamps in the system has not changed, and then the control flow returns to function module 1509. If the value of V3 is not equal to the original value V3p, the control flow jumps to conditional module 1513. If V3 is less than the original value V3p, it means that a new lamp is connected to the system, and the control flow jumps to function module 1514. The new V3 value is stored in variable V3p, and the new Dm value is divided by the maximum number of lamps N to obtain the new current share corresponding to each lamp. The counter variable m is restored to the maximum number of lamps N. U3 also needs to sample the voltage V4 reflecting the load current and save the V4 value to the variable V4p. The control flow jumps back to function module 1504. If V3 is greater than V3p, it means that some lamps have been removed from the system, and the control flow jumps to function module 1515.

[0126] For conditional module 1510, if Dm is not equal to Dmp, the control flow jumps to another conditional module 1518. If Dm is greater than Dmp, it means that the dimmer is adjusted up, and the control flow jumps to functional module 1519. The new dimming pulse width value Dm is first assigned to the brightness variable Lb and sent to the lamp. Then the control flow comes to functional module 1520. The brightness increment of each lamp is equal to the value of Dm minus Dmp, and then divided by the maximum number of lamps N, and then the control flow jumps back to functional module 1504.

[0127] For conditional module 1518, if Dm is less than Dmp, it means that the dimmer is adjusted downward, and the control flow jumps to function module 1521. The new dimming pulse width value Dm is assigned to the brightness variable Lb and sent to the lamp. Then the control flow comes to function module 1522. The brightness change Dstep of each lamp is equal to Dmp minus Dm, and then divided by the maximum number of lamps N. Then the control flow jumps to function module 1523, and sends it to PWM dimming control signal Cpwm minus Dstep, and then sends it to PWM dimming and analog dimming. Compatible constant current generating circuit, the loop counter m is reduced by 1, and then the control flow jumps to the function module 1524, the microcontroller U3 samples the voltage V4 reflecting the load current, and then the control flow comes to the conditional module 1525. If V4 is equal to the original value V4p, it means that the output current is still greater than the working current of all lamps in the current system, and then the control flow continues to the function module 1526, the loop counter is reduced by 1, and then the control flow comes to the conditional module 1527. If m is equal to 0, it means that there is no lamp in the system, and the control flow jumps to 1509. If m is greater than 0, the control flow jumps back to 1523. If V4 is not equal to the original value (less than the original value), it means that the output current is equal to the working current of all lamps in the system, and then the control flow jumps to the function module 1528, and the dimming PWM signal Cpwm returns to the value of the previous step.

[0128] For conditional module 1513, if V3 is greater than V3p, it means that a lamp has been removed from the system, and the control flow jumps to 1515. The new V3 value is saved to V3p, and then the current Dm value is divided by the maximum number of lamps N to calculate the current share Dstep of each lamp. The loop counter m is reassigned to N, and the microcontroller U3 samples the voltage V4 reflecting the load current, and stores V4 in V4p, and the control flow jumps to functional module 1523.
