Abstract
An energy saving controller for a large-screen advertising board comprises a light intensity detector, a control system, a power driver, and an alternating current power supply. The energy saving controller is characterized in that the control system is powered by the external alternating current power supply; the light intensity detector is located at the position of the large-screen advertising board, not interfered by non-natural light sources, and is connected with the control system; and the control system is connected with the power driver, and two output wires of the controller are serially connected to a power supply of the large-screen advertising board. The brightness of the large-screen advertising board can be regulated according to results of the light detector in detecting the ambient brightness. The energy saving controller has the advantages that the energy saving controller is low in cost, simple in structure, convenient to use, low in investment and high in return, and can be serially connected to the power supply circuit of the existing advertising board while the basic devices of the existing large-screen advertising board are unchanged; and the energy saving controller is more energy-saving, has promising market prospect, and meets the requirements of modern society for low carbon life.
Description
Technical field the present invention relates to a kind of energy saver, and it is a kind of giant-screen billboard energy-saving controller that relates to.
The giant-screen billboard that background technology is present, no matter night on daytime, no matter the cloudy day rains or is sunny, the giant-screen billboard all is a brightness, generally be to be benchmark can satisfy brightness conditions sun-drenched daytime, so also just there are two problems, 1, wastes energy (though a giant-screen billboard can not wasted a lot of energy, but there is too many billboard in a city, and these giant-screen billboards are work in 24 hours substantially at present, the energy of waste is a lot, does not meet the principle of current social energy-saving and emission-reduction); If 2, the giant-screen billboard is identical with the brightness on daytime night, sting eyes night especially, one influences resident's rest, and two consequences for passing driver's generation " dazzling " are especially all the more so for the amblyope.
Summary of the invention the present invention is directed to the deficiency that prior art has, and a kind of giant-screen billboard energy-saving controller is provided, and the brightness of giant-screen billboard is changed with the change of ambient brightness, thereby play the double effects of energy-conservation and anti-" dazzling ".
The present invention includes light intensity detector, control system, analog line driver, AC power, it is characterized in that: control system is powered by external AC power supply; Light intensity detector is positioned at the appropriate location that the giant-screen billboard is not disturbed by non-lamp, and links to each other with control system; Control system links to each other with analog line driver, and two lead series connection with controller output simultaneously are linked in the power supply of giant-screen billboard.
After adopting said structure, the giant-screen billboard can be adjusted the testing result of ambient brightness according to light intensity detector, if the ambient brightness height, then the brightness of giant-screen billboard also wants high; If the brightness of testing environment low (such as evening), then the brightness of giant-screen billboard also reduces; Basic principle is: along with the variation of ambient brightness, the brightness of giant-screen billboard also changes thereupon.
Advantage of the present invention is: 1, with low cost, simple in structure, easy to use, and invest for a short time, have high repayment, and under the immovable situation of existing giant-screen billboard basic device, only need this device series connection inserted and have the billboard feed circuit now and get final product; 2, have energy-saving effect and good market outlook preferably, meet the requirement of current social low-carbon (LC) life.
Appended drawings is theory diagram of the present invention.
Embodiment as shown in the figure, in the theory diagram of giant-screen billboard energy-saving controller, comprise multichannel light intensity detector 1, be averaging multichannel 2, PWM control 3, power drive 4, direct supply 5, giant-screen billboard 6, light intensity detector is positioned at the appropriate location that the giant-screen billboard is not disturbed by non-lamp, and be averaging multichannel and link to each other, through PWM control and power drive, two lead series connection that controller is drawn are linked in the power supply of giant-screen billboard; During use, establish a plurality of light intensity detectors in the appropriate location of giant-screen billboard, light intensity detector imports the signal that collects into to control system, control system is handled the signal of collecting, and the result after will handling is input in the analog line driver, by the voltage of analog line driver change giant-screen billboard dc power supply, realize adjusting with the variation of surrounding environment brightness the purpose of giant-screen billboard brightness with this, thereby reach purpose of energy saving.
