Abstract
The utility model relates to an LED (Light Emitting Diode) lamp tube which comprises an aluminum-based lamp panel, a constant current drive board and a voice detection controller, wherein the aluminum-based lamp panel is electrically connected with an LED and is arranged in the LED lamp tube, the constant current drive board is welded to a positive pole and a negative pole of the LED lamp tube through silica gel wires, the voice detection controller is electrically connected with the constant current drive board through a high-voltage optical coupler and is used for controlling the output power of the constant current drive board according to the intensity of a voice signal. According to the LED lamp tube provided by the utility model, the output power is automatically regulated according to different illumination environments so as to change the brightness.
Description
Technical field
The utility model relates to lighting field, relates in particular to a kind of LED fluorescent tube.
Background technology
At present, known LED lighting tube structure is to be combined by driving power, radiation aluminium shell, PC lampshade (full impregnated cover, frosted cover, striped cover etc.), aluminium base LED lamp plate, wire and lighting tube plug.The LED fluorescent tube that combines is installed on the tube stand, and staff is opened wall power source switch, LED lamp tube starting.General LED fluorescent tube is by switch control light on and off, can not automatically adjust power output and changes brightness, but not need the bright especially occasion that needs again to throw light on can not carry out hommization, Energy Saving Control.
Therefore, how making the LED fluorescent tube automatically adjust power output according to different lighting environments is technical issues that need to address to change brightness.
The utility model content
In order to solve the problems of the prior art, the utility model provides a kind of LED fluorescent tube, has solved LED and has automatically adjusted power output according to different lighting environments to change the technical problem of brightness.
The utility model provides a kind of LED fluorescent tube, comprising: aluminium base lamp plate, be electrically connected LED, and be built in the LED fluorescent tube; The constant current drive plate is by positive pole and the negative pole of silica gel wire bonds to described LED; With the sound detection controller, be electrically connected to described constant current drive plate by the high pressure optocoupler, according to the power output of the described constant current drive plate of the strong and weak control of voice signal.
LED fluorescent tube provided by the utility model detects the volume of lighting environment and automatically adjusts the power output of constant current drive plate with the brightness of change LED by the sound detection controller.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use among the embodiment, apparently, accompanying drawing in the following describes only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the circuit connection diagram of the utility model LED fluorescent tube;
Fig. 2 is the structure chart of the utility model LED fluorescent tube.
The specific embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is carried out clear, complete description, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
Be illustrated in figure 1 as the circuit connection diagram of LED fluorescent tube 1.The two ends of LED fluorescent tube 1 are connected to respectively live wire L and zero line N.Automatic control lamp pipe 1 total power output when this LED fluorescent tube 1 surpasses default decibel at ambient sound, fluorescent tube 1 are illuminated environment with maximum brightness, continue to exceed default decibel such as ambient sound and then continue to keep total power output, are controlled to be high-high brightness, satisfy the illumination needs.Preset decibel when ambient sound is lower than, its automatic control lamp pipe 1 enters the glimmer battery saving mode behind the Preset Time, and such as 2.5W, power is customizable.
Be illustrated in figure 2 as the structure chart of LED fluorescent tube 1.LED fluorescent tube 1 comprises aluminium base lamp plate, constant current drive plate 2 and sound detection controller 3.
Aluminium base lamp plate is electrically connected LED, is built in LED fluorescent tube 1.LED fluorescent tube 1 comprises plastic cement fluorescent tube 1 outer cover or glass lamp 1 outer cover.In the present embodiment, fluorescent tube 1 outer cover can be that the aluminium base lamp plate of LED places shell lamp plate draw-in groove in the horizontal double-colored fluorescent tube 1 plastic cement outer cover.The size design of LED fluorescent tube 1 is with traditional fluorescent tube 1 consistent size.
Constant current drive plate 2 guarantees LED lamp pearl current constant by positive pole and the negative pole of silica gel wire bonds to the LED fluorescent tube, does not work overloadingly.The input of constant current drive plate 2 is connected to external voltage.
Sound detection controller 3 compares according to established standards and detects control, is electrically connected to constant current drive plate 2 by high pressure optocoupler 4, according to the power output of the strong and weak control of voice signal constant current drive plate 2.Constant current drive plate 2 is arranged on the same wiring board with sound detection controller 3.
LED fluorescent tube provided by the utility model according to the brightness of ambient sound size intelligent control LED fluorescent tube, in some specific occasion, is controlled at the power saving low power consumpting state automatically, sends again faint but observable light simultaneously.
To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the utility model embodiment.Multiple modification to these embodiment will be apparent concerning those skilled in the art, and General Principle as defined herein can in the situation of the spirit or scope that do not break away from the utility model embodiment, realize in other embodiments.Therefore, the utility model embodiment will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
It below only is the preferred embodiment of the utility model embodiment; not in order to limit the utility model embodiment; all within the spirit and principle of the utility model embodiment; any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model embodiment.
