Description

Lighting control system

The invention relates to a lighting fixture control system, which can provide the effect of intelligent lighting and can reduce the energy consumption of lighting.

The traditional lighting devices are mainly incandescent lamps and fluorescent lamps. Although incandescent lamps are cheap and can provide stable and non-flickering light sources, their luminous efficiency is not good. Although the fluorescent lamp has a high luminous efficiency, it needs to be additionally equipped with a starter and a stabilizer, so it is often accompanied by noise when it is used, and the light source of the fluorescent lamp will have a problem of flicker.

With the advancement of technology, lighting devices have gradually evolved into energy-saving bulbs and LED (light emitting diode) lamps. The electronic ballast is integrated in the energy-saving bulb, and its structure is relatively strong, and its luminous efficiency is much higher than that of the incandescent lamp. In addition, LED lamps have higher luminous efficiency and service life, so they gradually become the mainstream lighting source.

As shown in the figure, the lighting lamp control system 10 according to the embodiment of the present invention mainly includes a control machine 11, at least one controller 13, a plurality of lighting lamps 15 and a plurality of network camera units 17, wherein the control machine 11 Each network camera unit 17 is electrically or communicatively connected, and the lighting fixture 15 is electrically connected through the controller 13.

In an embodiment of the present invention, the network camera unit 17 can be an Internet Protocol camera (IP Camera), which can be regarded as a type of digital camera. Specifically, the network camera unit 17 is used to capture images to generate image data 141, and transmit the image data 141 to the control machine 11 via the network. In addition, the control machine 11 can also send control signals to the network camera unit 17 and control the network camera unit 17.

Compared with the traditional CCTV camera, the network camera unit 17 transmits the image data 141 through a network cable or wirelessly, and is powered by ethernet (power over ethernet). The network camera unit 17 can provide higher-quality image data 141 for easy installation, and can provide real-time image data 141 to the control machine 11.

In an embodiment of the present invention, each network camera unit 17 can be set at a different location to capture images of different camera areas 183 and generate image data 141 respectively. In actual application, the adjacent imaging regions 183 may overlap with each other to improve the security of monitoring. Of course, the adjacent imaging regions 183 may not overlap to reduce the number of network camera units 17 and the installation cost. In addition, a mirror can be used in conjunction with the web camera unit 17 so that the web camera unit 17 can capture images through the mirror to increase the area of the camera area 183 that can be covered by a single web camera unit 17.

Each network camera unit 17 can be connected to the control machine 11 via a router 191. For example, the router 191 can be a wired or wireless router. Each network camera unit 17 can transmit image data 141 to the control machine 11 via the router 191. The control machine 11 can also send a control signal to the network camera unit 17 via the router 191 to control the network camera unit 17 to adjust the camera angle or zoom.

The control machine 11 can further analyze the image data 141 transmitted by the network camera unit 17, for example, the control machine 11 can be a computer, and a lighting lamp control program 111 can be installed, wherein the computer can analyze the image data 141 through the program. Specifically, the control machine 11 can be used to determine whether the image data 141 includes a preset image, such as a person or a vehicle.

The control machine 11 is electrically connected to the lighting fixture 15 through the controller 13, wherein the lighting fixture 15 can be used to generate a lighting source, and the controller 13 can be used to control the brightness and/or color temperature of the lighting source generated by the lighting fixture 15, such as lighting The lamp 15 may be a flat lamp. In an embodiment of the invention, the controller 13 may be a Dali controller (Digital Addressable Lighting Interface), and the lighting fixture 15 is a light-emitting diode (LED) fixture.

In practical applications, the controller 13 can be connected to each lighting fixture 15 through a power supply unit 12, wherein the controller 13 can send a control signal to the power supply unit 12, and the power supply unit 12 can send different currents and/or according to the control signal The voltage is applied to the lighting fixture 15 so that the lighting fixture 15 emits lighting sources with different brightness and/or color temperature.

When the controller 13 is a Dali controller, it will have 64 groups of addresses. Each lighting fixture 15 usually uses one address, so a single controller 13 can connect up to 64 sets of lighting fixtures 15 and can control each lighting fixture 15 separately.

In different embodiments, one lighting fixture 15 may also use two or more addresses. Although the number of lighting fixtures 15 connected and controlled by the controller 13 may be reduced, the controller 13 may perform For more detailed control, specific implementations will be described in detail in the following examples. Of course, the Dali controller and LED lamps are only an embodiment of the present invention and are not limited by the scope of the present invention. If different types of controllers are used, the number of lighting fixtures 15 that can be connected and controlled by a single controller 13 may also be different.

In an embodiment of the present invention, the controller 13, the lighting fixture 15 and the network camera unit 17 may be disposed in a lighting space 18, for example, the lighting space 18 may be an office, factory building, semiconductor manufacturing plant or parking lot. As shown in FIG. 2, the lighting space 18 may include a plurality of lighting areas 181, wherein the lighting sources generated by the lighting fixtures 15 may be projected in the lighting areas 181.

In practical applications, the illumination space 18, the illumination area 181, and the imaging area 183 are not limited to the rectangles shown in FIG. 2, and may be any other geometric shapes. In addition, the illumination areas 181 projected by the respective illumination light sources may partially overlap or not overlap. Of course, there may be a gap between adjacent illumination areas 181. Generally, if the lighting space 18 is an office, factory building, or semiconductor manufacturing plant, the adjacent lighting areas 181 usually overlap to provide a bright lighting space 18. Conversely, if the lighting space 18 is a parking lot, there may be a gap between adjacent lighting areas 181 to reduce the amount of electricity used for lighting.

The network camera unit 17 is used to capture the image of the camera area 183, and the lighting fixture 15 is used to project the lighting source in the lighting area 181, wherein the camera area 183 overlaps with at least one lighting area 181, such as the camera area 183 and the lighting The area 181 partially overlaps or completely overlaps.

In the embodiment of the present invention, as shown in FIG. 2, the area of the imaging area 183 is larger than the area of the illumination area 181. For example, a single imaging area 183 may include four illumination areas 181. Of course, in different embodiments, the area of the imaging area 183 may be approximately equal to the area of the illumination area 181, or the area of the imaging area 183 may be smaller than the area of the illumination area 181, but regardless of the area of the imaging area 183 and the illumination area 181 What is the relationship between the areas? The imaging area 183 basically overlaps the illumination area 181 partially or completely.

The control machine 11 is connected to the controller 13 and used to transmit a control signal 143 to the controller 13, and the controller 13 adjusts the brightness and/or color temperature of the lighting source generated by each lighting fixture 15 according to the received control signal 143.

When the control machine 11 determines that there is a preset image in the image data 141 captured by the network camera unit 17 in the imaging area 183, the control machine 11 will turn on the lighting fixture 15 relative to the imaging area 183, or adjust the lighting The brightness or color temperature of the lighting source generated by the lamp 15. For example, the controller 13 turns on the lighting fixture 15 of the lighting area 181 overlapping the imaging area 183, or the controller 13 increases the brightness of the lighting fixture 15 of the lighting area 181 overlapping the imaging area 183, so that the lighting fixture 15 projects the illumination light source To the illumination area 181 overlapping the imaging area 183, the imaging area 183 is illuminated.

Specifically, when the lighting fixture control system 10 of the present invention is applied in an office or factory building, the preset image may be a portrait. The control machine 11 can know from the network camera unit 17 which person in the office or factory is in the camera area 183, and further control the corresponding lighting fixture 15 to illuminate the camera area 183. In this way, each lighting fixture 15 will project an illumination light source as the person moves, so that the position of the person remains bright.

In an embodiment of the present invention, when no person enters the office or plant, the control machine 11 may control the lighting fixture 15 to maintain a low brightness. When the control machine 11 determines that a person enters the office or factory building, the brightness of the light source generated by some of the lighting fixtures 15 is increased with the position of the personnel movement, so that the lighting fixture 15 has the purpose of intelligent control and energy saving.

Of course, the lighting fixture control system 10 of the present invention can also be applied to parking lots, and the preset image can be a vehicle and/or a portrait. When the control machine 11 judges that a vehicle or a person enters the parking lot, it will increase the brightness of the illumination light source generated by some of the lighting fixtures 15 as the vehicle or the person moves.

In practical application, the overlapping lighting area 181 and the imaging area 183 can be set on the control machine 11 to establish the correlation between the lighting fixture 15 and the network camera unit 17. When the control machine 11 determines that the preset image appears in the imaging area 183, it turns on the lighting fixture 15 of the illumination area 181 overlapping the imaging area 183.

In different embodiments, the position of each lighting fixture 15 and each network camera unit 17 can also be set and stored in the control machine 11, for example, the coding of each lighting fixture 15 and each network camera unit 17 is established, in which the lighting area The lighting fixture 15 and the network camera unit 17 overlapping the 181 and the imaging area 183 may have the same or related codes. When the control machine 11 determines that a preset image appears in the imaging area 183 of the network camera unit 17, it will turn on the lighting fixture 15 having the same or related code as the camera unit 17.

Through the lighting fixture control system 10 of the present invention, the preset image of the control machine 11 can be set so that the control machine 11 will only pass through the controller when the preset image enters the imaging area 183 of the network camera unit 17 13 and/or the power supply unit 12 turns on the lighting fixture 15 or increases the brightness of the lighting fixture 15. Therefore, when the preset image stays still after entering the imaging area 183, the lighting fixture 15 corresponding to the imaging area 183 will not be turned off, nor will the brightness be reduced. In addition, when other objects that do not belong to the preset image enter the imaging area 183 or move within the imaging area 183, the lighting fixture 15 will not be turned on.

In contrast, the prior art can only simply control the lighting device to be turned on or off, and cannot turn on or off the lighting source according to the actual needs of the user, which not only causes inconvenience in use, but also fails to save energy.

In an embodiment of the invention, the lighting fixture control program 111 installed on the control machine 11 can adjust the brightness and/or color temperature of the lighting fixture 15 according to user settings. Specifically, the lighting fixture control program 111 can adjust the color temperature of the lighting fixture 15 according to time, for example, the color temperature of the lighting fixture 15 can be adjusted to about 5000K during the day to improve the work efficiency of the personnel, while the color temperature of the lighting fixture 15 at night can be adjusted It is about 3000K to alleviate the tension of overtime workers. In addition, the lighting fixture 15 can reduce the brightness during the lunch break to facilitate staff rest. The color temperature adjustment method of the lighting fixture 15 will be described in detail in the following embodiments.

In another embodiment of the present invention, the machine 11 may also be connected to the control device 11 through a mobile communication device 16, for example, the mobile communication device 16 may be a mobile phone, a smart phone, a tablet computer, or the like. Specifically, the mobile communication device 16 can communicate with the control machine 11 through a wireless router 193, and send a setting data 161 to the control machine 11 through the wireless router 193, and the control machine 11 will output the control signal 143 according to the setting data 161 Adjust the brightness and/or color temperature of the lighting fixture 15 to make the lighting fixture control system 10 more widely used. The setting data 161 may be the relationship between the brightness, color temperature and time of the lighting fixture 15. In practical applications, the router 191 and the wireless router 193 can also be integrated into a single device.

Please refer to FIG. 3, which is a block diagram of an embodiment of a lighting fixture and a controller of the lighting fixture control system of the present invention. As shown in the figure, in a practical example of the present invention, the controller 13 can be electrically connected to a lighting fixture 15 through a plurality of power supply units 121/123, so that the controller 13 can adjust the color temperature of the lighting source generated by the lighting fixture 15 through the power supply unit 12 And/or brightness.

In the embodiment of the present invention, the lighting fixture 15 may include a plurality of lighting units, such as a first lighting unit 151 and a second lighting unit 153, wherein each lighting unit 151/153 may respectively produce lighting sources with different color temperatures and/or wavelengths. The controller 13 is connected to each lighting unit 151/153 of the same lighting fixture 15 through different power supply units 121/123, for example, the controller 13 can be connected to the first lighting unit 151 through the first power supply unit 121 and through a second The power supply unit 123 is connected to the second lighting unit 153.

Since each lighting unit 151/153 can produce lighting sources with different color temperatures and/or wavelengths, the controller 13 can adjust the current and/or voltage output by the power supply units 121/123, for example, control the power supply units 121/123 to output different powers. To control the lighting units 151/153 to produce lighting sources with different brightnesses respectively, so that the lighting fixture 15 produces lighting sources with different color temperatures.

In an embodiment of the present invention, the power of the first lighting unit 151 may be a light-emitting diode with a power of 40W and a color temperature of 6000K, and the power of the second lighting unit 153 is a light-emitting diode with a power of 40W and a color temperature of 2500K. When the controller 13 controls the output current of the first power supply unit 121 to be greater than the output current of the second power supply unit 123, the brightness of the first lighting unit 151 will be greater than that of the second lighting unit 153, so that the color temperature of the lighting device 15 increases, such as 4500K. On the contrary, when the controller 13 controls the output current of the first power supply unit 121 to be smaller than the output current of the second power supply unit 123, the brightness of the first lighting unit 151 will be smaller than that of the second lighting unit 153, so that the color temperature of the lighting device 15 decreases. For example, 3000K.
