Description

Technical Field

[0001] The present application relates to an energy-saving lighting system. More specifically, the present application relates to an energy-saving lighting system that controls the brightness of light-emitting elements by using a microprocessor, a control unit, a power supply, a sensor, and / or a timer. Background Art

[0002] Common fluorescent tubes (fluorescent lamps) and LED fluorescent tubes (hereinafter referred to as traditional fluorescent tubes) on the market have a transformer inside each tube. Since the transformer also has a certain amount of power loss when operating at no load, when traditional fluorescent tubes start to emit light, the transformer in each tube will cause excess power loss. Especially when installing multiple traditional fluorescent tubes, the excess power loss is even more serious.

[0003] Furthermore, in most environments, the brightness of traditional fluorescent tubes cannot be adjusted to suit the environment. If the number of users decreases or they leave the environment (for example, in parking lots or hospitals at night), maintaining the brightness of traditional fluorescent tubes at maximum or normal brightness will inevitably result in excessive power loss. In view of this, how to improve the power loss of each transformer in multiple traditional fluorescent tubes when in the no-load state and how to control and adjust the brightness of the tubes according to the current environmental conditions, thereby improving the light emission efficiency and energy saving of the tubes, are urgent problems to be solved in the field to which this application belongs. Utility Model Content

[0004] In order to solve at least the above-mentioned problems, the present application provides an energy-saving lighting system. The energy-saving lighting system includes a plurality of transformer-free 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 to generate a first control signal and transmit the first control signal to the microprocessor. The sensor is electrically connected to the microprocessor. The sensor has a sensing range. When the sensor detects that an object moves within the sensing range, it generates a sensing signal and transmits the sensing signal to the microprocessor. The power supply includes a transformer, which 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] In order to solve the above problems, the present application also provides an energy-saving lighting system. The energy-saving lighting system includes a plurality of transformer-free light-emitting elements, a microprocessor, a control unit, a timer, a storage and a power supply. The control unit is electrically connected to the microprocessor to generate a first control signal and transmit the first control signal to the microprocessor. The timer is electrically connected to the microprocessor to provide at least one specified time value and transmit the specified time value to the microprocessor. The storage is electrically connected to the microprocessor to store a preset time value. The power supply also includes a transformer, which is electrically connected to the microprocessor and the light-emitting elements, wherein the microprocessor determines whether the specified time value meets the preset time value to generate a specified time signal, and generates an adjustment signal according to 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 this application connects multiple transformer-free light-emitting devices via a power supply with a single transformer. This prevents the significant power loss caused by the simultaneous operation of multiple transformers when multiple light-emitting devices are in operation. Furthermore, the microprocessor can adjust the brightness of the multiple transformer-free light-emitting devices based on the results of the at least one sensor or within a specified timer. Thus, the energy-saving lighting system of this application effectively overcomes the aforementioned problems.

[0010] The present application will be described below through a number of embodiments, but these embodiments are not intended to limit the present application to being implemented only according to the described operations, environments, applications, structures, processes or steps. Elements that are not directly related to the present application are not shown in the drawings, but may be implied in the drawings. In the drawings, the sizes of the elements and the ratios between the elements are only examples and are not intended to limit the present application. Unless otherwise specified, in the following content, the same (or similar) element symbols may correspond to the same (or similar) elements. Where practicable, unless otherwise specified, the number of each element described below may be one or more.

[0011] The terms used in this disclosure are only used to describe the embodiments and are not intended to limit the present application. Unless the context clearly indicates otherwise, the singular form "one" is also intended to include the plural form. Terms such as "include", "comprising" indicate the presence of the 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 the aforementioned combinations. The term "and / or" includes any and all combinations of one or more listed items. Although the terms "first", "second" and the like may be used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish between each element. Therefore, for example, without departing from the spirit and scope of the present application for which protection is requested, a first element described below may also be referred to as a second element.

[0012] Figure 1 The schematic diagram of the architecture of the first embodiment of the energy-saving lighting system 1 of the present application is illustrated. Figure 1 What is shown is only for the purpose of illustrating certain embodiments of the present application and should not be construed as any limitation on the application as claimed.

[0013] Reference Figure 1 The present application provides an energy-saving lighting system 1. The energy-saving lighting system 1 may generally include a plurality of transformer-free light-emitting elements (hereinafter referred to as light-emitting elements) 10A, 10B, and 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] Because the light-emitting elements 10A, 10B, and 10C of the energy-saving lighting system 1 of the present application do not include a transformer, when the output power of the power supply 60 causes the light-emitting elements 10A, 10B, and 10C to emit light, there is no unnecessary transformer to cause power loss. For example, taking a typical 4-foot fluorescent tube with a transformer as an example, a traditional T9 fluorescent tube consumes approximately 47W of power, an electronic T8 fluorescent tube consumes approximately 41W of power, and an LED fluorescent tube consumes approximately 20W of power. If 120 tubes are used simultaneously, the daily power consumption for a traditional T9 fluorescent tube is approximately 135 kWh (1 kWh = 1,000W), an electronic T8 fluorescent tube consumes approximately 118 kWh of power, and an LED fluorescent tube consumes approximately 57.6 kWh of power. Because the light-emitting elements 10A, 10B, and 10C of the present application do not include a transformer, the power consumption of a single light-emitting element is approximately 10W. In other words, if 120 light-emitting elements of the present application are used simultaneously, the daily power consumption is approximately 28.8 kWh, thereby significantly reducing unnecessary power loss.

[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 certain embodiments of the present application, the light emitting elements 10A, 10B, and 10C may be transformer-free lamp tubes, transformer-free LED lamp tubes, or transformer-free LED light strips. It should be noted that the present application does not limit the type and quantity of the light emitting elements.

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

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

[0019] like Figure 1As shown, when a user operates the control unit 30, the control unit 30 generates a first control signal CS1 and transmits the first control signal CS1 to the microprocessor 20. Furthermore, the sensor 40 (using 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 generates an adjustment signal AS based on 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 via the control unit 30 of the energy-saving lighting system 1. For example, the control unit 30 may be installed on the equipment 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 use the control unit 30 to adjust the brightness to, for example, but not limited to, 100%, 75%, 50%, or even 25%. After the user's operation, the control unit 30 transmits a first control signal CS1 to the microprocessor 20. The microprocessor 20 adjusts the brightness of the light-emitting elements 10A, 10B, and 10C based on the first control signal CS1. The user can decide whether to adjust the brightness based on usage habits, usage needs, and the brightness requirements of the on-site environment, thereby reducing unnecessary power loss.

[0021] In certain embodiments of the present application, since the sensors 40 of the energy-saving lighting system 1 can detect moving objects within their sensing range, when the sensors 40 are installed in a public space (e.g., an indoor or outdoor parking lot at night, a hospital, a shopping mall, an office building, etc.), a desired number of sensors 40 can be deployed in the public space. When these sensors 40 detect a person passing within their sensing range, they transmit a sensing signal SS to the microprocessor 20. The microprocessor 20 then generates an adjustment signal AS based on the sensing signal SS and transmits 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 periods of high traffic, the sensors 40 will sense a person in the public space and transmit a sensing signal SS. The adjustment signal AS generated by the microprocessor 20 then turns the light-emitting elements 10A, 10B, and 10C on at 100% maximum brightness. When the sensor 40 does not sense a user in the public space, the sensor 40 does not send any sensing signal SS. Therefore, the adjustment signal AS sent 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 certain embodiments of the present application, 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 serve as a basis for the microprocessor 20 to subsequently adjust the brightness of the light-emitting elements. Specifically, the user can, as needed, store the first control signal CS1 generated by the control unit 30 as a preset control signal and store the sensing result of the public space by the sensor 40 as a preset sensing signal. The microprocessor 20 can then determine whether the subsequently generated first control signal CS1 and sensing signal SS match 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, consequently, the brightness of the light-emitting elements 10A, 10B, and 10C.

[0023] Figure 2 A schematic diagram illustrating the architecture of another embodiment of the energy-saving lighting system of the present application is shown. Figure 2 The content shown is only for illustrating certain embodiments of the energy-saving lighting system of the present application, and is not intended to limit the scope of protection of the present application.

[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 for providing at least a specified time value ST and transmitting the specified time value ST to the microprocessor 20. A memory 50 is electrically connected to the microprocessor 20 for storing a preset time value DT. The microprocessor 20 determines whether the specified time value ST matches the preset time value DT to generate a specified time signal (not shown). The microprocessor 20 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] The storage 50 may include a primary storage device (e.g., memory) that stores instruction sets read by the microprocessor 20. In some embodiments, in addition to the primary storage device, the storage 50 may also include a secondary storage device (e.g., a hard drive, an optical disk) that connects to the microprocessor 20 via an internal I / O channel and uses a data buffer to transfer data to the primary storage device. In some embodiments, in addition to the primary and secondary storage devices, the storage 50 may also include a tertiary storage device (e.g., a flash drive, a cloud drive) that can also copy data to the secondary storage device.

[0026] In other words, the energy-saving lighting system 2 can pre-store various time periods (i.e., various preset time values ​​DT) in the memory 50 according to user needs. When the timer 70 sends the specified time value ST to the microprocessor 20, and the microprocessor 20 determines that the preset time value DT has been reached, the microprocessor 20 will generate the specified time signal and generate the adjustment signal AS based on the specified time signal to achieve the most efficient use of the light-emitting elements 10A, 10B, and 10C.

[0027] For example, the intensity of sunlight varies over time, so the timer 70 can divide a day into ten to twelve periods, issuing designated time values ​​ST in stages. This will be simplified below as representing the three time periods of morning, noon, and evening. For example, the memory 50 can pre-store preset time values ​​DT for the three time periods of morning, noon, and evening. Since sunlight is slightly stronger in the morning, the timer 70 sets 9:00 AM as the designated time value ST. When the designated time value ST is transmitted to the microprocessor 20, the microprocessor 20 determines whether the designated time value ST matches the preset time value DT. If so, the brightness of the light-emitting elements 10A, 10B, and 10C is adjusted to 75%. Since sunlight is strongest at noon, the timer 70 sets 12:00 PM as the second designated time value ST, adjusting the brightness of the light-emitting elements 10A, 10B, and 10C to 100%. The sunlight is weakest at night, and the number of users decreases gradually after get off work, so the timer 70 sets 18:00 as the third designated time value ST, and adjusts the brightness of the light-emitting elements 10A, 10B, and 10C to 50%, thereby reducing unnecessary power loss.

[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 commute. If the sensors 40 detect a user passing through the public space, the brightness of the light-emitting elements 10A, 10B, and 10C can be adjusted to 80%. Since the number of users decreases in the evening and there is no sunlight outside the window, the indoor lighting does not require such high brightness. Therefore, at 6:00 PM during the evening commute, the brightness of the light-emitting elements 10A, 10B, and 10C can be set to a lower value of 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 can be adjusted to, for example, 50% or 60%. This reduces unnecessary power consumption.

[0029] In certain embodiments of the present application, Figure 1 and Figure 2As shown, the energy-saving lighting system 1 and the energy-saving lighting system 2 further include a feedback circuit (not shown) electrically connected to the microprocessor 20 and the power supply 60. The feedback circuit is used to detect the output power of the power supply 60 and generate a detection signal (not shown). The microprocessor 20 generates an adjustment signal AS based on the detection signal and adjusts the output power of the power supply 60. For example, the feedback circuit can continuously detect the output power of the power supply 60. If the output power provided by the power supply 60 is too high, resulting in an output overload, the output mode can be changed to a constant current mode, thereby locking the output current value and preventing it from increasing. The output voltage will decrease as the load increases.

[0030] Furthermore, in certain embodiments of the present application, 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 heat sink (not shown), and a temperature-controlled fan (not shown). The temperature detector, the PWM crystal heat sink, and the temperature-controlled fan are all connected to the microprocessor 20. When the temperature detector senses that the temperature of the PWM crystal heat sink has reached a standard value (for example, 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 to lower the temperature of the PWM crystal heat sink, and 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 certain embodiments of the present application, 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 and is used to receive a second control signal (not shown) sent by a terminal device (not shown), such as a mobile phone, tablet or computer device, through remote control. When the transceiver unit receives the second control signal, it transmits the second control signal to the microprocessor 20, and 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, 10C, thereby reducing unnecessary power loss.

[0032] The above embodiments are merely examples to illustrate the present application and are not intended to limit the scope of protection of the present application. Any other embodiments resulting from modifications, changes, adjustments, or integrations of the above embodiments, as long as they are readily conceivable by a person of ordinary skill in the art to which the present application belongs, are encompassed within the scope of protection of the present application. The scope of protection of the present application shall be determined by the claims.
