Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
The embodiment of the present invention accesses constant current unit by after multiple LED lamp bead electrical connection, described constant current unit is electrically connected with input signal process and dimmer pulse output unit, described input signal process and dimmer pulse output unit receive the control signal that Energy Saving Control unit exports, described control signal is processed into the constant current signal that described constant current unit is controlled, luminous by demand by described constant current unit driving LED lamp pearl again, meet power conservation requirement.Thus, this LED light engine module can be widely used in various lighting device, as bulb lamp, Down lamp, fluorescent lamp, wall lamp, Projecting Lamp etc.
Below in conjunction with specific embodiment, realization of the present invention is described in detail.
As shown in Figure 1, the LED light engine module that the embodiment of the present invention provides comprises multiple LED lamp bead 1, and multiple LED lamp bead 1 is electrically connected rear access constant current unit 2, and described constant current unit 2 is electrically connected with input signal process and dimmer pulse output unit 3; Described input signal process and dimmer pulse output unit 3 receive the control signal that Energy Saving Control unit 4 exports, and described control signal are processed into the constant current signal controlled described constant current unit 2.Multiple LED lamp bead 1 is electrically connected rear access constant current unit 2 herein, described constant current unit 2 is electrically connected with input signal process and dimmer pulse output unit 3, the control signal that Energy Saving Control unit 4 exports is received by described input signal process and dimmer pulse output unit 3, described control signal is processed into the constant current signal that described constant current unit 2 is controlled, luminous by demand by described constant current unit 2 driving LED lamp pearl again, to meet power conservation requirement.
The unit of Energy Saving Control described in the embodiment of the present invention 4 has the first interface 41 of confession sound-optical controller access or/and the second interface 42 of Thermoelectric Infrared Sensor access.Corresponding controller or sensor can be selected according to actual conditions like this, insert the corresponding interface, convenient, fast.Usually, described input signal process and dimmer pulse output unit 3 include single-chip microcomputer; Described constant current unit 2 includes current constant control IC, and described current constant control IC has light modulation pin or signal detection pin.Certainly, can integrated acousto-optic controller signals processing unit and Thermoelectric Infrared Sensor signal processing unit onboard.
In addition, described LED light engine module also comprises the dimming unit regulated according to the brightness of on-off times to LED lamp bead 1, makes it to have wall-board switch dimming function.Wherein, the luminance parameter of described LED lamp bead 1 is stored in EEPROM.Described on-off times is circulated by wall-board switch knob and produces or wall-board switch button ON/OFF circulation generation.As preferably, the LED lamp bead that described LED lamp bead 1 is connected for polycrystalline, can reduce the quantity of LED lamp bead like this, saves space on plate.
Should be noted that, the EEPROM that single-chip microcomputer after the energising of this LED light engine module in the input signal process of its inside and dimmer pulse output unit 3 reads its inside obtains luminance parameter, this single-chip microcomputer exports different dimmer pulse according to different luminance parameter, control constant current unit 2 and export different average currents, then LED lamp bead 1 sends different brightness.Store next switch output brightness parameter after the pulse of described single-chip microcomputer output brightness and enter EEPROM, to read next time.Above action all performs after each switch energising.
After above having stable behavior (no matter in which brightness), input signal process and dimmer pulse output unit 3 constantly can detect sound-optical controller signal input interface (i.e. first interface 41) and Thermoelectric Infrared Sensor signal input interface (i.e. the second interface 42).If after corresponding signal being detected, after signal transacting made by the single-chip microcomputer of its inside, adjustment exports pulse and regulates LED luminance size or close LED action.Such as, wall-board switch light modulation brightness shelves: 100%-50%-20%.Sound light control functionality: A, daytime all do not work with/without sound LED; There are sound LED in B, evening bright 1 minute.Refer to following table.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
