Description

Technical Field

[0001] This invention relates to an energy-saving lighting system. More specifically, this invention relates to an energy-saving lighting system that controls the brightness of a light-emitting element by means of a microprocessor, a control unit, a power supply, a sensor, and / or a timer. Background Technology

[0002] In general, each fluorescent tube (fluorescent lamp) and LED fluorescent tube (hereinafter referred to as traditional fluorescent tube) on the market has a transformer inside. Since the transformer will also have a certain power loss when it is operating under no-load, when the traditional fluorescent tube starts to emit light, the transformer in each tube will cause extra power loss. Especially when many traditional fluorescent tubes are installed, the extra power loss is even more significant.

[0003] Furthermore, in most usage environments, the brightness of traditional fluorescent tubes cannot be adjusted according to the environment. If the number of users in the environment decreases, or if users leave the environment (e.g., in a parking lot or hospital at night), continuously maintaining the brightness of traditional fluorescent tubes at the highest or normal level will inevitably result in unnecessary power consumption. Therefore, how to improve the power consumption of each transformer in a plurality of traditional fluorescent tubes under no-load conditions, and how to control and adjust the brightness of the tubes according to the current environmental conditions, thereby improving the luminous efficiency and energy-saving efficiency of the tubes, is a problem that urgently needs to be solved in the field of this invention. Summary of the Invention

[0004] To address at least the aforementioned problems, the present invention provides an energy-saving lighting system. This energy-saving lighting system includes a plurality of transformerless light-emitting elements, a microprocessor, a control unit, at least one sensor, and a power supply. The control unit is electrically connected to the microprocessor and generates a first control signal, which is then transmitted to the microprocessor. The sensor is electrically connected to the microprocessor and has a sensing range. When the sensor detects an object moving within the sensing range, it generates a sensing signal and transmits this signal to the microprocessor. The power supply includes a transformer and is electrically connected to the microprocessor and the light-emitting elements. The microprocessor generates an adjustment signal based on the first control signal or the sensing signal to adjust the output power of the power supply, thereby adjusting the brightness of the light-emitting elements.

[0005] To address the aforementioned problems, the present invention also provides an energy-saving lighting system. This energy-saving lighting system includes a plurality of transformerless light-emitting elements, a microprocessor, a control unit, a timer, a memory, and a power supply. The control unit is electrically connected to the microprocessor and generates a first control signal, which is then transmitted to the microprocessor. The timer is electrically connected to the microprocessor and provides at least one specified time value, which is then transmitted to the microprocessor. The memory is electrically connected to the microprocessor and stores a preset time value. The power supply further includes a transformer, which is electrically connected to the microprocessor and the light-emitting elements. The microprocessor determines whether the specified time value matches the preset time value, generates a specified time signal, and generates an adjustment signal based on the first control signal or the specified time signal to adjust the output power of the power supply, thereby adjusting the brightness of the light-emitting elements.

[0006] The energy-saving lighting system of the present invention can connect a plurality of transformerless light-emitting elements to a power supply having a transformer. This avoids the significant power loss caused by multiple transformers operating simultaneously when multiple light-emitting elements operate concurrently. Furthermore, the microprocessor can adjust the brightness of the plurality of transformerless light-emitting elements based on the results sensed by at least one sensor or according to a specified time interval. Accordingly, the energy-saving lighting system of the present invention effectively overcomes the aforementioned problems.

[0010] The present invention will be described below through several embodiments; however, these embodiments are not intended to limit the invention to being practiced only according to the described operations, environments, applications, structures, processes, or steps. Elements not directly related to the present invention are not shown in the drawings, but may be implied therein. In the drawings, the dimensions of the elements and the proportions between them are merely exemplary and not intended to limit the invention. Unless otherwise specified, in the following description, the same (or similar) element symbols may correspond to the same (or similar) elements. Where feasible, unless otherwise specified, the quantity of each element described below may be one or more.

[0011] The terminology used in this disclosure is for illustrative purposes only and is not intended to limit the invention. Unless the context clearly indicates otherwise, the singular form “a” is intended to include the plural form as well. Terms such as “comprising,” “including,” etc., indicate the presence of the stated features, integers, steps, operations, elements, and / or components, but do not exclude the presence of one or more other features, integers, steps, operations, elements, components, and / or combinations thereof. The term “and / or” includes any and all combinations of one or more of the listed items. Although the terms “first,” “second,” etc., may be used herein to describe various elements, such elements should not be limited by these terms. These terms are used only to distinguish individual elements. Therefore, by example, a first element described below may also be referred to as a second element without departing from the spirit and scope of the claimed invention.

[0012] Figure 1 A schematic diagram illustrating the architecture of a first embodiment of the energy-saving lighting system 1 of the present invention is shown. Figure 1 The contents shown are merely illustrative of certain embodiments of the present invention and should not be construed as any limitation on the claimed invention.

[0013] Reference Figure 1 This invention provides an energy-saving lighting system 1. The energy-saving lighting system 1 generally includes a plurality of transformerless light-emitting elements (hereinafter referred to as light-emitting elements) 10A, 10B, 10C, a microprocessor 20, a control unit 30, at least one sensor 40, and a power supply 60. The microprocessor 20 is electrically connected to the control unit 30, the sensor 40, and the power supply 60, and the light-emitting elements 10A, 10B, and 10C are electrically connected to the power supply 60.

[0014] Since the light-emitting elements 10A, 10B, and 10C of the energy-saving lighting system 1 of this invention do not have transformers, when the output power of the power supply 60 causes the light-emitting elements 10A, 10B, and 10C to emit light, there is no excess transformer causing power loss. For example, taking a typical 4-foot fluorescent tube with a transformer as an example, the power consumption of a traditional T9 fluorescent tube is approximately 47W, the power consumption of an electronic T8 fluorescent tube is approximately 41W, and the power consumption of an LED fluorescent tube is approximately 20W. If 120 tubes are used simultaneously, the daily power consumption is approximately 135 kWh for a traditional T9 fluorescent tube (1 kWh = 1,000W), approximately 118 kWh for an electronic T8 fluorescent tube, and approximately 57.6 kWh for an LED fluorescent tube. Since the light-emitting elements 10A, 10B, and 10C of this invention do not have transformers, the power consumption of a single light-emitting element is approximately 10W. In other words, if 120 light-emitting elements of the present invention are used at the same time, the daily power consumption is about 28.8 kWh, thus significantly reducing unnecessary power consumption.

[0015] The microprocessor 20 may include: a central processing unit (CPU), a digital signal processor (DSP), a microprocessor, and / or a microcontroller, etc.

[0016] In some embodiments of the present invention, the light-emitting elements 10A, 10B, and 10C may be transformerless lamp tubes, transformerless LED lamp tubes, or transformerless LED strips. It should be noted that the present invention does not limit the type or number of light-emitting elements.

[0017] In some embodiments of the present invention, the control unit 30 is a touch panel. Additionally, in some embodiments of the present invention, the sensor 40 may be an infrared sensor, a microwave sensor, or a voice-activated sensor. It should be noted that the present invention does not limit the type or number of sensors.

[0018] In some embodiments of the invention, the power supply 60 includes a transformer 60A.

[0019] like Figure 1As shown, when the user operates the control unit 30, the control unit 30 can generate a first control signal CS1 and transmit the first control signal CS1 to the microprocessor 20. Additionally, the sensor 40 (taking one sensor as an example, but not limited to this) has a sensing range. When the sensor 40 detects an object moving within its sensing range, it generates a sensing signal SS. Based on the above, the microprocessor 20 can generate an adjustment signal AS according to the first control signal CS1 or the sensing signal SS to adjust the output power of the power supply 60, thereby adjusting the brightness of the light-emitting elements 10A, 10B, and 10C.

[0020] like Figure 1 As shown, the user can adjust the brightness of the light-emitting elements 10A, 10B, and 10C using the control unit 30 of the energy-saving lighting system 1. For example, the control unit 30 can be installed on the device of the energy-saving lighting system 1, and the user can operate the control unit 30 to adjust the brightness of the light-emitting elements. For example, the user can adjust the brightness to, but not limited to, 100%, 75%, 50%, or even 25% through the control unit 30. After the user operates, the control unit 30 will transmit the first control signal CS1 to the microprocessor 20, and the microprocessor 20 will adjust the brightness of the light-emitting elements 10A, 10B, and 10C according to the first control signal CS1. The user can decide whether to adjust the brightness according to their usage habits, usage needs, and the brightness requirements of the environment, thereby reducing unnecessary power consumption.

[0021] In some embodiments of the present invention, since the sensor 40 of the energy-saving lighting system 1 can sense moving objects within its sensing range, when the sensor 40 is installed in a public space (such as indoor or outdoor parking lots, hospitals, shopping malls, and office buildings at night), a plurality of sensors 40 can be installed in this public space as needed. If these sensors 40 detect a person passing by within their sensing range, they will transmit a sensing signal SS to the microprocessor 20. The microprocessor 20 will generate an adjustment signal AS based on the sensing result of the sensing signal SS and transmit the adjustment signal AS to the power supply 60 to adjust the output power of the transformer 60A, thereby adjusting the brightness of the light-emitting elements 10A, 10B, and 10C. For example, during times of frequent personnel movement, these sensors 40 will detect users in the public space and emit a sensing signal SS. The adjustment signal AS emitted by the microprocessor 20 will then cause the light-emitting elements 10A, 10B, and 10C to turn on at 100% maximum brightness. When the sensor 40 does not detect a user in the public space, the sensor 40 will not emit any sensing signal SS. Therefore, the adjustment signal AS emitted by the microprocessor 20 will reduce the brightness of the light-emitting elements 10A, 10B, and 10C to, for example, but not limited to, 25% to 75% or 40 to 60%, thereby reducing unnecessary power consumption.

[0022] In some embodiments of the present invention, the energy-saving lighting system 1 includes a memory 50 electrically connected to the microprocessor 20. The memory 50 can be used to store a first control signal CS1 and a sensing signal SS, which can then be used as the basis for the microprocessor 20 to adjust the brightness of the light-emitting elements. Specifically, the user can store the first control signal CS1 generated by the control unit 30 as a preset control signal, and store the sensing result of the sensor 40 on the public space as a preset sensing signal. Then, the microprocessor 20 can determine whether the subsequently generated first control signal CS1 and sensing signal SS conform to the preset control signal and the preset sensing signal, thereby generating an adjustment signal AS to adjust the output power of the power supply 60, and thus adjust the brightness of the light-emitting elements 10A, 10B, and 10C.

[0023] Figure 2 A schematic diagram illustrating another embodiment of the energy-saving lighting system of the present invention is shown. Figure 2 The contents shown are merely illustrative of certain embodiments of the energy-saving lighting system of the present invention, and are not intended to limit the scope of protection of the present invention.

[0024] like Figure 2As shown, unlike the first embodiment, the energy-saving lighting system 2 includes a timer 70 electrically connected to the microprocessor 20 to provide at least one specified time value ST and transmit the specified time value ST to the microprocessor 20. The memory 50 is electrically connected to the microprocessor 20 to store a preset time value DT. The microprocessor 20 determines whether the specified time value ST matches the preset time value DT, generates a specified time signal (not shown), and generates an adjustment signal AS based on the first control signal CS1 or the specified time signal to adjust the output power of the power supply 60, thereby adjusting the brightness of the light-emitting elements 10A, 10B, and 10C.

[0025] Storage 11 may include a first-level storage device (e.g., a memory) and may store the instruction set read by microprocessor 20. In some embodiments, in addition to the first-level storage device, storage 11 may also include a second-level storage device (e.g., a hard disk or optical disk), which is connected to microprocessor 20 via an internal I / O channel and uses a data buffer to transfer data to the first-level memory. In some embodiments, in addition to the first-level and second-level storage devices, storage 11 may also include a third-level storage device (e.g., a USB flash drive or cloud drive), which may also copy data to the second-level storage device.

[0026] In other words, the energy-saving lighting system 2 can store each time period (i.e. each preset time value DT) in the memory 50 according to the user's needs. When the timer 70 sends a specified time value ST to the microprocessor 20 and the microprocessor 20 determines that the preset time value DT has been received, the microprocessor 20 will generate the specified time signal and generate an adjustment signal AS according to the specified time signal so that the light-emitting elements 10A, 10B, and 10C can achieve the most efficient use.

[0027] For example, the intensity of sunlight changes over time, so the timer 70 can divide a day into ten to twelve stages, issuing a specified time value ST for each stage. The following explanation simplifies this to three time periods: morning, noon, and evening. For instance, the memory 50 can pre-store preset time values ​​DT for these three periods. Since sunlight is slightly stronger in the morning, the timer 70 sets 9:00 AM as a specified time value ST. When the specified time value ST is transmitted to the microprocessor 20, the microprocessor 20 will determine if the specified time value ST matches the preset time value DT. If they match, the brightness of the light-emitting elements 10A, 10B, and 10C will be adjusted to 75%. At noon, sunlight is strongest, so the timer 70 sets 12:00 PM as a second specified time value ST, adjusting the brightness of the light-emitting elements 10A, 10B, and 10C to 100%. Since sunlight is weakest at night and the number of users gradually decreases after get off work, the timer 70 sets 18:00 as the third specified time value ST and adjusts the brightness of the light-emitting elements 10A, 10B, and 10C to 50% to reduce unnecessary power consumption.

[0028] Furthermore, the timer 70 can also be used in conjunction with the sensors 40 of the first embodiment. For example, the brightness of the light-emitting elements 10A, 10B, and 10C can be set to 60% at 9:00 AM during the morning rush hour. If the sensors 40 detect a user passing through the public space, the brightness of the light-emitting elements 10A, 10B, and 10C will be adjusted to 80%. Since the number of users decreases at night and there is no sunlight outside the windows, such high indoor lighting is not necessary. Therefore, at 6:00 PM during the evening rush hour, the brightness of the light-emitting elements 10A, 10B, and 10C can be set to a lower 25% or 30%. If the sensors 40 detect a user passing through the public space, the brightness of the light-emitting elements 10A, 10B, and 10C will be adjusted to, for example, 50% or 60%. This reduces unnecessary power consumption.

[0029] In some embodiments of the present invention, such as Figure 1 and Figure 2As shown, energy-saving lighting system 1 and energy-saving lighting system 2 further include a feedback circuit (not shown). This feedback circuit is electrically connected to microprocessor 20 and power supply 60 to detect the output power of power supply 60 and generate a detection signal (not shown). Microprocessor 20 generates an adjustment signal AS based on the detection signal and adjusts the output power of power supply 60. For example, this feedback circuit can detect the output power of power supply 60 at any time. If the output power provided by power supply 60 is too high, causing output overload, the output mode can be changed to constant current mode, thereby locking the output current value and preventing it from rising, while the output voltage will decrease as the load increases.

[0030] Furthermore, in some embodiments of the present invention, the energy-saving lighting system 1 and the energy-saving lighting system 2 are also equipped with a temperature detector (not shown), a PWM crystal heatsink (not shown), and a temperature-controlled fan (not shown). The temperature detector, the PWM crystal heatsink, and the temperature-controlled fan are all connected to the microprocessor 20. When the temperature detector senses that the temperature of the PWM crystal heatsink has reached a standard value (e.g., but not limited to 85 degrees Celsius), it sends a temperature signal (not shown) to the temperature-controlled fan and the microprocessor 20. This causes the temperature-controlled fan to operate and reduce the temperature of the PWM crystal heatsink, while the microprocessor 20 generates an adjustment signal AS to adjust the output power of the power supply 60 and reduce the temperature of the light-emitting elements 10A, 10B, and 10C.

[0031] In some embodiments of the present invention, the energy-saving lighting system 1 and the energy-saving lighting system 2 further include a transceiver unit (not shown), which is electrically connected to the microprocessor 20 to receive a second control signal (not shown) from a terminal device (not shown), such as a mobile phone, tablet or computer device, via remote control. When the transceiver unit receives the second control signal, it transmits the second control signal to the microprocessor 20. The microprocessor 20 generates an adjustment signal AS based on the second control signal and adjusts the output power of the power supply 60, thereby adjusting the brightness of the light-emitting elements 10A, 10B, and 10C to reduce unnecessary power consumption.

[0032] The above embodiments are merely illustrative of the present invention and are not intended to limit the scope of protection of the present invention. Any other embodiments resulting from modifications, changes, adjustments, or integrations to the above embodiments, as long as they are readily conceived by those skilled in the art, are covered within the scope of protection of the present invention. The scope of protection of the present invention is defined by the claims.
