Description
Technical field
The present invention relates to a kind of lighting apparatus, particularly a kind of LED lamp and comprise the LED control system of this LED lamp.
Background technology
Along with the popularization of low-carbon energy-saving idea, the LED lamp has obtained using widely at lighting field.In the city lighting engineering, LED guardrail pipe, LED decorative lamp and LED underground lamp along the street need adopt a plurality of LED lamps or a plurality of LED lamp group to constitute the system that can set off each other and coordinate just can have extraordinary visual effect.So need carry out independent control to each LED or each LED lamp group through a system, control its operating state at any time, comprise the light on and off state, the color of brightness and demonstration.
Method to the control of LED control system property comprises following several kinds at present:
1, adopts wired LED control system; As shown in Figure 1; This LED control system is transferred to repeater through holding wire (comprising twisted-pair feeder) with the control signal of PC master control; Repeater is distributed to a plurality of iversion controllers with this control signal through holding wire (comprising twisted-pair feeder) then, each iversion controller and the series connection of a plurality of led light source, and this iversion controller can convey to the operating state that any led light source can be controlled a plurality of led light sources along the led light source of connecting with control signal.Though this kind scheme can be controlled each led light source and do any variation, because a plurality of LED connect, break down so can cause needing only a led light source, then can cause a plurality of led light source cisco unity malfunctions, so its reliability is relatively poor.And if the quantity of increase iversion controller makes each divide control control a LED lamp, this has not only increased the cost of iversion controller, has also increased wiring cost.
2, in order to solve the problem that exists in the technique scheme 1, people had found out other a kind of LED control system again afterwards, and promptly at the inner integrated control module of each led light source, each led light source is controlled by connected control module.Because each led light source is controlled by control module independently, the control signal of each led light source does not influence each other, so the reliability of this control system is better; But owing to each control module is connected with other controllers, so in order to reach the purpose of Autonomous Control led light source, the control program of each control module is all good in project installation burning in advance before; Can not change, though this kind control method preferably resolves the integrity problem of system, because the control program of each control module can not change; Caused difficult in maintenance; The display effect that this led light source forms is single, and simultaneously in order to save cost, the control program of each led light source all is the same; So can only be used for the identical occasion of product variations; If the control program of each led light source is all write as different, make each led light source form a systematic change pattern, then this can give to manufacture and install and bring huge difficulty.
