Description

Technical Field

[0001] This invention relates to the field of decorative lighting technology, and more specifically to a high-voltage intelligent lighting device. Background Technology

[0002] Existing intelligent decorative lighting products are mainly developed along three technological routes.

[0003] One approach is the low-voltage adapter route: the mains power is stepped down to low-voltage DC (such as 5V, 12V, 24V or 36V) by an external power adapter to power the lamp body, and an addressing IC is installed inside the lamp body to realize lamp-by-lamp control. This route has the following inherent problems: (1) Each product must be equipped with a power adapter, which is costly, and the waterproof rating of the adapter is generally low, which becomes a weak link for outdoor use; (2) the voltage drop of the low-voltage supply is significant, the length of a single string is limited, and the brightness at the end of a long string is reduced; (3) the expansion of multiple strings is limited by the power cap of the adapter, making it difficult to freely continue the connection.

[0004] The second type is the direct-connection AC power line: the lamp body is directly connected to the AC power. Existing products using this approach either only support a unified string mode without individual lamp addressing capability, or each lamp head has a built-in complete AC-DC driver module and wireless communication module, essentially a series of independent smart lamps. This results in high cost per lamp, large size, and numerous potential failure points, making it unsuitable for mini light strings or other small lamp head products. Due to the long-term influence of electrical safety regulations and certification costs, the smart decorative lighting industry has continued to develop along the low-voltage adapter route, leading to a technical consensus that products requiring individual lamp address codes must use low-voltage power supply.

[0005] Thirdly, there is the high-voltage RGB LED strip lighting route that has emerged in recent years: the LED strip is directly connected to the mains power, and after rectification, it supplies power to the series-connected light-emitting units, which have built-in driver ICs. However, in this route, the light-emitting units are cascaded sequentially along the data lines and take data in sequence, without address codes. It is not possible to arbitrarily specify the light-emitting unit by address. When connecting or mixing different units, the entire lighting sequence is extended sequentially, making it impossible to achieve a unified or coordinated lighting effect after connecting multiple sets of products. Furthermore, the failure of a single light-emitting unit in the cascaded link will cause all subsequent light-emitting units to go out.

[0006] In summary, existing technologies lack an intelligent lighting architecture that is directly powered by mains electricity, feeds power to each light-emitting unit via a high-voltage DC bus, and requires only an IC and address code for each light-emitting unit without the need for individual lamp AC-DC drive modules. Summary of the Invention

[0007] To address the aforementioned technical problems, the present invention aims to provide a high-voltage intelligent lighting device, which is achieved through the following technical solution: A high-voltage intelligent lighting device includes a main control unit and several light-emitting units; the input terminal of the main control unit is connected to the mains power, and the main control unit outputs a high-voltage DC bus voltage; each light-emitting unit is connected in series and / or in parallel to the high-voltage DC bus, and the light-emitting unit is equipped with an IC and an address code.

[0008] Optionally, each light-emitting unit's IC can extract data corresponding to its own unit from the control data transmitted from the high-voltage DC bus based on its own pre-set address code at the factory, and drive the light-emitting element of its unit to present the corresponding lighting effect; each light-emitting unit does not need to rewrite the address code on-site during use.

[0009] Optionally, a separate data cable is also included; Use any of the following settings: Setting Method 1: Each light-emitting unit is connected in parallel to an independent data line. The IC of each light-emitting unit extracts the data corresponding to its own unit from the control data broadcast and transmitted by the independent data line according to its own preset address code, and drives the light-emitting element of its unit to present the corresponding light effect. Setting Method 2: Each light-emitting unit is cascaded sequentially via an independent data line. After the IC of each light-emitting unit intercepts the data header corresponding to its own unit, it shapes and forwards the remaining data to the next light-emitting unit.

[0010] Optionally, the light-emitting unit is connected to the high-voltage DC bus via a lamp holder with only two electrical contacts.

[0011] Optionally, the light-emitting unit has a non-replaceable sealed structure, and the light-emitting element pins and wires have a non-removable fixed connection mechanism.

[0012] Optionally, the light-emitting units are of a connectable structure; the light-emitting units of each lamp group in the same product specification are pre-set with the same address code segment at the factory; when multiple lamp groups are connected end to end with a connector or connected to the same main control device through a branch connector, the light-emitting units with the same address code in each lamp group present a uniform lighting effect.

[0013] Optionally, multiple different types of lamp groups can be connected to the same high-voltage DC bus of the main control device; when different types of lamp groups use different address code segments, the light-emitting units of each type of lamp group present a coordinated and differentiated lighting effect.

[0014] Optionally, at least one light-emitting unit includes two or more independently controlled light-emitting areas, each of which is independently driven by the IC of this unit according to multiple channels in the address code corresponding to the data.

[0015] Optionally, the light-emitting unit is provided with a failure bypass structure, and the clamping element connected in parallel to both ends of the light-emitting element conducts freewheeling current when the light-emitting element is open, and / or the IC detects that the light-emitting element of this unit has failed and conducts the bypass of this unit so that the other light-emitting units can continue to work.

[0016] Optionally, the high-voltage DC bus voltage is greater than 48V, obtained from the mains power through rectification and filtering.

[0017] The present invention has the following beneficial effects: The system architecture combines "high-voltage power supply" and "lamp-by-lamp addressing." On one hand, eliminating the need for a low-voltage power adapter for each product reduces system costs and eliminates the vulnerability of external adapters in outdoor waterproofing and failure scenarios. On the other hand, the high-voltage DC bus can transmit power with a smaller current under the same power conditions, thus reducing line voltage drop and increasing the length of a single string and the number of connections. Simultaneously, each light-emitting unit does not require a complete AC-DC driver module; only an IC and address code suitable for the high-voltage bus are needed. This reduces lamp head size and single-lamp cost, and allows for smaller product forms such as mini light strings. Attached Figure Description

[0018] The present invention will be further described with reference to the accompanying drawings, but the embodiments in the drawings do not constitute any limitation on the present invention. For those skilled in the art, other drawings can be obtained based on the following drawings without creative effort.

[0019] Figure 1 This is a schematic diagram of the system architecture of a high-voltage intelligent lighting device according to the present invention; Figure 2 This is a circuit block diagram of the light-emitting unit in one embodiment of the present invention; Figure 3 This is a schematic diagram of multi-lamp group connection and mixing in one embodiment of the present invention. Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] In the description of this invention, it should be noted that the terms "vertical," "upper," "lower," "horizontal," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0022] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or a connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0023] Example 1 (Infrastructure): As Figure 1 As shown, the main control device's input is connected to 120V AC mains power, and outputs a DC bus voltage of approximately 120V-160V after internal rectifier bridge and filter capacitor. In areas with 220V AC mains power, the main control device also outputs a DC bus voltage in the range of 100V-170V after rectification, filtering, and voltage adjustment. Fifty light-emitting units are connected in parallel to this bus. Each unit contains an IC and address codes 1-50. The light-emitting elements are high-voltage LED filaments or high-voltage COB light sources (internally composed of multiple LED chips connected in series) with forward voltages compatible with the bus voltage. The MCU / data modulation module within the main control device modulates and loads control data onto the bus. The IC is a high-voltage linear constant current drive IC, directly connected across the bus to draw power and intercepting data according to the address code. Control data is transmitted via the bus, and the IC of each unit intercepts the corresponding data according to the address code, driving the unit to present dynamic effects such as sequential running lights and flowing water.

[0024] Example 2 (Topology Variation): Two light-emitting units with a rated voltage of approximately 60V are connected in series and then bridging a 120V bus to form a series voltage divider topology. Preferably, the bus is a straight main line running through the beginning and end of the light string. Multiple light-emitting units are connected in series to form a light segment. Each light segment is distributed along the straight main line and connected to the straight main line for power supply, forming a series-parallel hybrid topology. A splice connector is provided at the end of the straight main line. The main line of the next light group is extended in parallel through this splice connector to avoid the voltage drop caused by the line extension affecting the end light-emitting unit. Under each topology, the light-emitting units independently retrieve data according to the address code and do not affect each other.

[0025] Example 3 (Lamp holder shape): as shown Figure 2As shown, the light-emitting unit is connected to the busbar via a screw-type or socket-type lamp holder with only two electrical contacts, such as E26, E17, or E12. Because the lamp holder has only two electrical contacts, control data is transmitted via the power lines that constitute the busbar. The light-emitting element is a high-voltage LED filament. If the light-emitting unit fails, it can be replaced with a unit with the same address code. In another embodiment, the light-emitting unit is a non-replaceable sealed structure, with the light-emitting element pins riveted to the wires and fused for insulation, providing waterproof and anti-detachment capabilities. It should be noted that if the voltage of the high-voltage DC bus exceeds the safe extra-low voltage range, and the light-emitting unit adopts a structure that can be plugged and replaced by the user, the exposed live contacts during the replacement process pose a risk of electric shock, which is not conducive to passing safety standard certification. Moreover, consumers cannot know the original preset address codes of each lamp position. If the light-emitting unit is replaced arbitrarily, or if two light-emitting units are swapped, and their address codes do not match the original preset address codes of that position, it will cause the entire string of lights to be disordered, which contradicts the architecture of not needing to rewrite the address codes on site. Therefore, in the preferred embodiment of this device, the light-emitting unit adopts a fixed and sealed structure that cannot be replaced, so that the factory preset address codes, the need for rewriting the address codes, and the reliability of safety regulations are mutually compatible.

[0026] Example 4 (Independent Data Line): The light assembly uses a three-core cable, of which two cores are high-voltage DC busbars and the third core is an independent data line; in one embodiment, each light-emitting unit is connected in parallel to the data line, and the corresponding data is extracted from the broadcast data according to the address code; in another embodiment, each light-emitting unit is cascaded sequentially via the data line, and the IC extracts the data corresponding to its own unit from the beginning of the data stream, and then shapes and forwards the remaining data to the next light-emitting unit. Each unit presents the effect according to the physical position order. When multiple strings are connected, the light effect extends continuously from the beginning of the first string to the end of the last string.

[0027] Example 5 (Continuing with the unified effect): As Figure 3 As shown, the address code segment for a 50-LED string is 1-50, and the address code segment for a 100-LED string is 1-100. When two 50-LED strings are connected end-to-end with a connector, the second string with addresses 1-50 will have the same lighting effect as the first string. When 50-LED and 100-LED strings are connected together, the first 50 addresses will have a uniform lighting effect. These address code segments are pre-programmed at the factory during LED assembly and do not require rewriting or re-addressing during use. This differs from addressing schemes that require a secondary address rewriting procedure after assembly. Users can simply plug and play without any configuration. Multiple LED groups can also be connected in parallel to the same main control device via branch connectors, and the lighting units with the same address code in each LED group will have a uniform lighting effect.

[0028] Example 6 (Hybrid Connection Synergy Effect): As Figure 3As shown, curtain lights (address code segment 1-50), icicle lights (address code segment 51-100), and net lights (address code segment 101-150) are all connected to the high-voltage DC bus of the same main control device. Under the same frame of control data, the curtain lights present a flowing effect, the icicle lights present a breathing effect, and the net lights present a flashing effect, forming a coordinated differentiated scene. If all three types of lights use address code segment 1-50, then each light group will present the same effect.

[0029] Example 7 (Multi-Light-Emitting Area Unit): A single light-emitting unit is equipped with two or more independent light-emitting areas (such as an upper light-emitting area and a lower light-emitting area). The IC of this unit drives each light-emitting area to present different colors or effects simultaneously according to multiple channels in the data corresponding to the address code (such as RGBW four channels or RGBCW five channels). Since the control data is transmitted through the bus or data line, there is no need to increase the number of wire cores when adding light-emitting areas.

[0030] Example 8 (Failure Bypass): As Figure 2 As shown, Zener clamping elements are connected in parallel across the light-emitting elements of the light-emitting unit. When the light-emitting element is open, the clamping elements conduct and continue current. Alternatively, the IC may detect a failure of the light-emitting element in this unit and actively bypass the unit. A single-point failure does not affect the operation of other light-emitting units. In a series branch, this structure also maintains the branch conduction.

[0031] Example 9 (Product Form and Light-Emitting Element): The light-emitting element of the light-emitting unit is at least one of multiple LED chips connected in series, high-voltage LED filaments, or high-voltage COB light sources; the carrier of the light-emitting unit covers string lights (Christmas mini string lights, C6 / C7 / C9 string lights, G40 bulb string lights, E26 bulb string lights, curtain lights, icicle lights, net lights, waterfall lights, dense string lights, eaves lights, ground-insert string lights, neon rope lights, light strips, decorative lights, pre-installed Christmas trees, light trees, fairy lights) and non-string light carriers (factory-prefabricated fixed splicing light panels, decorative light frames, downlight groups, point light source modules, spotlights, floodlights, wall lights, pillar lights, floor lamps, table lamps, porch lights, path stake lights, step lights, deck lights, treetop lights, candle lights, pre-installed light wreaths, pre-installed light vines), as well as smart bulbs (A19, PAR38, and other standard bulbs) in light groups fed by high-voltage DC bus; applicable to both indoor and outdoor scenes.

[0032] Example 10 (Indoor Ambient Light): This device can also be used as an indoor ambient lighting product: After the main control device is connected to the mains power, the high-voltage DC bus runs along the indoor light trough, baseboard, or wall, and several light-emitting units are connected to the bus. The IC of each light-emitting unit intercepts control data according to the address code preset at the factory, presenting a zoned and gradual ambient lighting effect. Since no external power adapter is required, there is no power module in the light trough, the wiring is simple, and when multiple light strips are extended through the connector or branch connector, the light-emitting units with the same address code present a uniform effect, which is suitable for indoor scenes such as living rooms, bedrooms, and display cabinets. When used as an indoor floor lamp or table lamp, the mains power is connected to the main control device in the form of a main control box through a plug. The main control box outputs a high-voltage DC bus, which runs along the inside of the lamp post. Multiple light-emitting units are connected in sections along the height of the lamp post, and each section presents a segmented or gradual lighting effect according to the address code; the main control device can also be located in the lamp base. No external power adapter or cascade data cable is required on the lamp post or lamp body.

[0033] Example 11 (Openness of Control Method): Control data can be generated by at least one of the following methods: physical remote control button signals, mobile terminal application, voice commands, or pre-stored programs in the main control device; the control method does not constitute a limitation on the scope of protection of this invention.

[0034] This invention proposes a high-voltage intelligent lighting device, including a main control device and several light-emitting units; the input terminal of the main control device is connected to the mains power, and the main control device outputs a high-voltage DC bus voltage; each light-emitting unit is connected in series and / or in parallel to the high-voltage DC bus, and the light-emitting unit is equipped with an IC and an address code.

[0035] The mains power first enters the main control unit, where rectification, filtering, and necessary voltage processing are performed internally to form a high-voltage DC bus exceeding the traditional extra-low voltage range. Multiple light-emitting units draw power directly from this high-voltage DC bus, unlike traditional low-voltage smart lighting fixtures where an external adapter first converts the mains power to low-voltage DC (5V, 12V, 24V, or 36V) before supplying the light strings. Simultaneously, each light-emitting unit is equipped with an internal IC and an independent address code, enabling the main control unit to identify different light-emitting units based on their addresses, thus establishing the foundation for individual light-by-light control. Embodiment 1 in the specification further illustrates how 120V mains power is transformed into an approximately 120V-160V DC bus by the main control unit, with multiple light-emitting units connected in parallel to the bus and directly powered by a high-voltage linear constant current drive IC.

[0036] The main advantage of this technical solution lies in combining "high-voltage power supply" and "lamp-by-lamp addressing" in the system architecture. On the one hand, eliminating the need for a low-voltage power adapter for each product reduces system costs and eliminates the vulnerability of external adapters in outdoor waterproofing and failure scenarios. On the other hand, the high-voltage DC bus can transmit power with a smaller current under the same power conditions, thus reducing line voltage drop and increasing the length of a single string and the number of connections. Simultaneously, each light-emitting unit does not require a complete AC-DC driver module; only an IC and address code suitable for the high-voltage bus are needed, which helps reduce the size of the lamp head and the cost per lamp, and adapts to smaller product forms such as mini light strings.

[0037] In a preferred embodiment, each light-emitting unit's IC extracts data corresponding to its own unit from the control data transmitted from the high-voltage DC bus according to its own pre-set address code at the factory, and drives the light-emitting element of its unit to present the corresponding lighting effect; each light-emitting unit does not need to rewrite the address code on-site during use.

[0038] Address recognition capability is fixed within the light-emitting unit. The main control device can send data containing control information corresponding to multiple addresses to the entire bus. When each light-emitting unit receives the same control data, it does not simply retrieve the data sequentially according to the physical arrangement. Instead, the IC reads its own preset address code, identifies and extracts the data content belonging to its own address from the control data, and then executes only the light control corresponding to its own unit. In this way, the logical identity of the light-emitting unit is determined by its address code, rather than entirely by its physical position in the light string.

[0039] Its beneficial effects are mainly reflected in improved system scalability and ease of use. Traditional systems that require on-site addressing or rewriting often need to reconfigure addresses after lamp group continuation, addition of lamp groups, or recombination; this solution, by pre-setting the address code at the factory, eliminates the need for users to perform additional address writing operations during subsequent use and continuation. Embodiments 1 and 5 in the specification clearly state that multiple lamp groups can be connected "plug and play, without any configuration operations." Furthermore, since the control relationship relies on logical addresses rather than simply physical order, it also provides a basis for subsequent claims such as unified effects for different lamp groups and mixed-connection control.

[0040] In a preferred embodiment, an independent data line is also included; each light-emitting unit is connected in parallel to the independent data line, and the IC of each light-emitting unit extracts the data corresponding to its own unit from the control data broadcast and transmitted by the independent data line according to its own preset address code, and drives the light-emitting element of its own unit to present the corresponding light effect.

[0041] Power supply and data transmission are separated. The high-voltage DC bus only provides power, while the third independent data line broadcasts control data. The main control unit can send the same frame of control data to all light-emitting units on the independent data line. Each light-emitting unit can receive the complete broadcast data, but since each unit has a preset address code, each IC only extracts the portion that matches its own address for execution.

[0042] The beneficial effect of this technical solution is that it provides a data transmission method for high-voltage power supply systems that differs from power line carrier or bus data multiplexing. This solution can be adopted when certain product structures or control requirements are more suitable for separating power lines and data lines, while still maintaining the ability to address each lamp independently. Since each light-emitting unit is connected in parallel to the data line, its control relationship is not inherently constrained by the physical cascading order of the preceding and following lamps, avoiding data link dependency caused by a single preceding unit only being responsible for forwarding, while maintaining the flexibility of address-based broadcast control. Embodiment 4 explicitly describes one implementation of the independent data line as follows: each light-emitting unit is connected in parallel and the corresponding data is extracted from the broadcast data according to the address code.

[0043] In a preferred embodiment, an independent data line is also included; each light-emitting unit is cascaded sequentially via the independent data line, and after the IC of each light-emitting unit intercepts the data stream header corresponding to the data of its own unit, it shapes and forwards the remaining data to the next light-emitting unit.

[0044] Its working principle is a step-by-step forwarding control. Control data enters from the first light-emitting unit. After the first light-emitting unit takes or identifies its own data, it shapes the remaining data and then transmits it to the next light-emitting unit. Subsequent light-emitting units continue to process the data in the same way, thus forming a control data stream that propagates step-by-step along the physical link. The embodiments in the specification indicate that, in this way, each unit can present the effect according to the physical position sequence, and after multiple strings are connected, the lighting effect can extend continuously from the beginning of the first string to the end of the last string.

[0045] Its beneficial effect lies in providing an alternative data transmission scheme for products that require sequential lighting effects, flowing lighting effects, or continuous display according to physical arrangement. Compared with the broadcast addressing mode of the previous implementation, this implementation is more suitable for scenarios that require lighting effects to unfold continuously along a physical sequence. At the same time, each IC reshapes the data before forwarding it, which helps maintain the integrity of data transmission in long links and enables the high-voltage power supply architecture to be compatible with the cascaded control logic commonly used in traditional RGB LED strips.

[0046] In a preferred embodiment, the light-emitting unit adopts any of the following structures: The first type involves connecting the light-emitting unit to the high-voltage DC bus via a lamp holder with only two electrical contacts; the lamp holder is a screw-type lamp holder. The second type involves connecting the light-emitting unit to the high-voltage DC bus via a lamp holder with only two electrical contacts; the lamp holder is a plug-in lamp holder. The third type has a non-replaceable sealed structure for the light-emitting unit, and the light-emitting element pins and wires are fixedly connected by a non-removable mechanism, such as riveting and fusion sealing insulation.

[0047] For the two-contact lamp holder design, the principle is to utilize only two electrical contacts to simultaneously bear the high-voltage DC power supply, and to complete data transmission through the same pair of lines when using busbar transmission for control data, thus eliminating the need to add independent data contacts for each lamp holder. Example 3 lists two-contact screw-in or socket lamp holders such as E26, E17, and E12. For the fixed sealing design, the light-emitting element is directly riveted to the wire and then welded shut, fixing and insulating the electrical connection points, preventing users from arbitrarily replacing them.

[0048] Its beneficial effects are twofold: firstly, it reduces the structural complexity of lamp holders and lamp heads, making it particularly suitable for small lamp head products; secondly, in high-voltage DC environments, the non-replaceable sealing structure prevents the exposure of live contacts during user disassembly, improving safety, reliability, and waterproof performance. Example 3 also specifically points out that if users arbitrarily replace lamp beads with different preset address codes, it will lead to a misalignment of the address and lamp position preset relationship. Therefore, the fixed sealing structure can maintain the stability of the factory address configuration, ensuring a balance between "preset address code, no on-site address writing, and safety compliance reliability."

[0049] In a preferred embodiment, the light-emitting unit has a connectable structure; the light-emitting units of each lamp group in the same product specification are pre-set with the same address code segment at the factory; when multiple lamp groups are connected end to end with a connecting wire or connected to the same main control device through a branch connector, the light-emitting units with the same address code in each lamp group present a uniform lighting effect.

[0050] Synchronization of multiple light groups is achieved using "address code multiplexing". For example, if two 50-LED strings both use addresses 1-50, then "address 1" in both strings will receive the same control data, and "address 2" in both strings will also receive the same data, and so on. In this way, regardless of whether the light groups are connected end-to-end or in parallel via branch connectors, as long as they are within the same main control system, light-emitting units with the same address can automatically execute the same control command.

[0051] Its beneficial effect is to solve the problem of address sequence continuously accumulating after multiple strings of traditional sequentially addressed LED strips are connected, resulting in a sequential extension of the lighting effect of subsequent LED groups. This solution ensures that different LED groups have the same logical address structure at the factory. Therefore, after multiple LED groups are connected, there is no need to re-address them, and they can directly obtain mirrored, synchronized, or unified lighting effects. The instruction manual clearly explains using two 50-LED strings as an example that after the two strings are connected, the addresses 1-50 of the second string can present the same effect as the first string.

[0052] In a preferred embodiment, multiple different types of lamp groups are connected to the high-voltage DC bus of the same main control device; when different types of lamp groups use different address code segments, the light-emitting units of each type of lamp group present a coordinated and differentiated lighting effect.

[0053] Different product types are logically partitioned using address space. For example, curtain lights use addresses 1-50, icing lights use 51-100, and mesh lights use 101-150. The main control device sends different control information to different address ranges in the same data frame. Each type of light group only reads data belonging to its own address range, thus enabling the execution of different lighting effects such as flowing, breathing, and flashing. Example 6 clearly illustrates this.

[0054] Its beneficial effect lies in enabling different types of lighting fixtures, which traditionally require multiple controllers to manage separately, to be centrally connected to the same high-voltage DC power supply and control system. This reduces the number of main control devices and wiring complexity, while also enabling unified scene orchestration across product types. Different lighting groups can choose the same address range for synchronization, or different address ranges for differentiated collaboration, thus significantly improving system configuration flexibility.

[0055] In a preferred embodiment, at least one light-emitting unit includes two or more independently controlled light-emitting areas, each of which is independently driven by the IC of the unit according to multiple channels in the address code corresponding to the data.

[0056] The data corresponding to a logical address is further divided into multiple control channels. For example, a light-emitting unit may have two light-emitting areas, upper and lower, or multiple control channels such as RGBW and RGBCW. After receiving the data corresponding to this unit, the IC does not output a single unified drive signal, but controls different light-emitting areas according to different channels in the data, so that a physical lamp unit can simultaneously display different colors, brightness, or lighting effects.

[0057] Its beneficial effect is to improve the performance of a single light-emitting unit without increasing the number of main circuits in the system due to the increase in the light-emitting area. Example 7 clearly states that since control data is still transmitted through the bus or data line, increasing the light-emitting area does not require increasing the number of wire cores. This allows for richer local lighting effects while maintaining simple wiring.

[0058] In a preferred embodiment, the light-emitting unit is provided with a failure bypass structure. The clamping element connected in parallel to both ends of the light-emitting element conducts freewheeling current when the light-emitting element is open-circuited, and / or the IC conducts the bypass of the unit when it detects that the light-emitting element of the unit has failed, so that the other light-emitting units continue to work.

[0059] To prevent a single light-emitting element in a series branch from opening and cutting off the current to the entire branch, the bypass structure ensures that the light-emitting element remains operational during normal operation. When a light-emitting element opens, a Zener clamping element or an IC-controlled bypass path takes over the current path, ensuring that subsequent light-emitting units still have a current path. The specifications clearly state that a single-point failure does not affect the operation of other light-emitting units and maintains branch continuity even in series branches.

[0060] Its beneficial effect is to solve the cascading failure problem of high-voltage RGB LED strips, where "if one light-emitting unit fails, all subsequent units may go out," thereby improving the fault tolerance of the light assembly and the reliability of the system. This is especially important for long strings, multiple strings, high-position installations, or outdoor products, as it can prevent the failure of the entire product due to a single point of failure.

[0061] In a preferred embodiment, the high-voltage DC bus voltage is greater than 48V and is obtained from the mains power through rectification and filtering.

[0062] The system directly utilizes mains power, which is rectified and filtered by the mains control device to form a high-voltage DC power supply, instead of first stepping down the voltage to a safe extra-low voltage before long-distance transmission. Corresponding to Embodiment 1, the high-voltage DC bus referred to in this article is a DC voltage greater than 48V, used to distinguish it from traditional SELV low-voltage lighting systems.

[0063] Its beneficial effects are primarily reflected in the reduction of transmission current and line losses. At the same power level, increasing the transmission voltage reduces line current, thereby mitigating voltage drop and end-brightness attenuation issues in long-distance transmission, allowing for a significant increase in single-string length and the number of connections. Secondly, directly rectifying the mains power to form a high-voltage DC bus eliminates the need for separate external low-voltage power adapters, allowing the main control unit to centrally handle power conversion, reducing system complexity and cost. The manual summarizes this as "high-voltage, low-current transmission, thinner wire diameter, lower voltage drop, and a significant increase in single-string length and the number of connections."

[0064] The components, modules, mechanisms, and devices in this invention that are not described in detail are all general standard parts or components known to those skilled in the art. Their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0065] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the essence and scope of the technical solutions of the present invention.
