Below with reference to accompanying drawing and example the utility model is described in further detail:
The utility model proposes a kind of wireless remote control light modulation LED apparatus, described wireless remote control light modulation LED apparatus comprises remote control transmitter and Dimmable LED light-emitting device, described Dimmable LED light-emitting device comprises receiver of remote-control sytem, Dimmable LED driver and LED matrix, and described remote control transmitter carries out ON/OFF and brightness adjustment control by the wireless remote control mode to described Dimmable LED light-emitting device.Use this wireless remote control light modulation LED apparatus, ON/OFF and brightness regulation that can the remote control LED light-emitting device, easy to use, energy-conservation.
Shown in Fig. 1～3 three kinds of different Dimmable LED luminous device structure schematic diagrames in the utility model wireless remote control light modulation LED apparatus example.As shown in the figure, this Dimmable LED light-emitting device 100 comprises LED fixation kit 110, led light source 111, Dimmable LED driver 120 and signal receiver 121.Wherein the LED fixation kit can be lamp panel, lampshade, support, metal decking etc., and this assembly also provides thermolysis for LED in fixed L ED.Led light source 111 can be LED point-source of light or LED area source or the LED line source etc. more than 1 or 1.It is inner or outside that Dimmable LED driver 120 can be installed in LED fixation kit 110.Signal receiver 121 (for example infrared sensor or radio frequency reception antenna) can be installed in the inside or the outside of Dimmable LED driver 120, reception is from the dim signal of remote control transmitter 200 emissions, by control Dimmable LED driver 120, drive and regulate the brightness of LED then.
Shown in Fig. 4～7 four kinds of different remote control transmitter structural representations in the utility model wireless remote control light modulation LED apparatus example.Remote control transmitter 200 panels comprise can for the user regulate brightness increase, reduce button and/or shift knob and/or channel, button be set.Remote control transmitter 200 circuit comprise coding circuit and radiating circuit, and user's light modulation information via is provided with the coding back by the wireless mode emission, and described remote control transmitter comprises single or multiple channels.
Shown in Figure 9 is Dimmable LED light-emitting device circuit block diagram in the utility model wireless remote control light modulation LED apparatus example.As shown in the figure, signal receiver 121 receives the remote control light modulating signal that sends from remote control transmitter 200 and handles, and signal receiver 121 includes that signal receives, decoding circuit 1211 and channel and/or ID selective addressing circuit 1212, PWM modulation circuit 1213.Signal reception, decoding circuit 1211 receive the remote control light modulating signals and signal are decoded, the dim signal of channel and/or 1212 pairs of receptions of ID selective addressing circuit is decoded and addressing, perhaps use the ID of the correspondence that prestores in it that dim signal that receives is decoded, and channel difference or the not corresponding signal of ID are ignored.Digital dimming signal through decoding output can directly link to each other with the dimming interface of led driver 122, perhaps modulate through PWM modulation circuit 1213 through the digital dimming signal of decoding output, output PWM dim signal links to each other with the dimming interface of led drive circuit 122, thereby realize the on/off switch of forward LED electric current, recently increase or reduce the effective average current of LED forward by changing duty, reach the brightness of regulating led light source 111.
Shown in Figure 10 is led drive circuit 122 circuit diagrams in the utility model wireless remote control light modulation LED apparatus example.This example circuit is to adopt the LED single channel of PWM light modulation to drive the series connection light adjusting circuit, and this circuit comprises light modulation drive circuit 1221, serial light adjusting circuit 1222.IC1 can select LTC3783, LTC3476, TPS6106X, EL7801 etc. for use and the single channel or the multi-channel LED light modulation drive IC of similar functions are arranged in the light modulation drive circuit 1221.Single channel light modulation drive circuit 1221 is the example explanation with the LTC3783 drive IC in this example, and this IC inside comprises a current regulation error amplifier, switched-mode power supply (SMPS) controller and a PWM or the digital dimming controller with fet driver.The current error amplifier adopts the pressure drop at detection resistance R 8 two ends that are in series with LED, with accurate adjusting LED electric current.Integrated fet driver is used to drive a N channel power MOS FETQ1 and a N raceway groove load PWM switch Q2.PWMin input dim signal 12211 not only drives PWMout, but also will enable controller GATE switch and error amplifier operation, can make controller in PWMin storage LED load current information during for low level.Recently control the switching tube MOSFET Q2 conducting and the disconnection of connecting by the duty that changes PWMin dim signal 12211, carry out light modulation thereby change the effective average current of LED with LED.The dynamic range of duty ratio (DDim) has defined the high-high brightness rank that PWM light modulation configuration can realize.LED brightness and forward current are proportional, and therefore resulting the highest and minimum LED current average is represented by following formula (1) and (2) respectively when using PWM light modulation configuration:
ILED_Max＝DDim_Max?x?ILED (1)
ILED_Min＝DDim_Min?x?ILED (2)
Wherein, ILED is the LED electric current, and ILED_Max is the average peak of LED electric current, and ILED_Min is the average minimum of LED electric current, and DDim_Max is the maximum dimmer duty ratio, and DDim_Min is minimum light modulation duty ratio.Therefore, the PWM dimming scope can be used following formula (3) expression:
Dimming scope=DDim_Max/DDim_Min (3)
Relation between formula (3) expression PWM dimming scope and maximum, the minimum light modulation duty ratio.For given light modulating frequency FDim, DDim_Max represents maximum duty cycle, and promptly the LED electric current is reduced to the zero time from required forward current (IF) before the next light modulation cycle begins; DDim_Min represents minimum duty cycle, and promptly the LED electric current is by the zero time that rises to required forward current (IF).
Be minimum and maximum PWM light modulation duty ratio schematic diagram shown in Figure 11～13, as shown in the figure, DDim_Max and DDim_Min can use following formula (4) and (5) expression:
DDim_Max＝(T-tSD)/T (4)
DDim_Min＝(tD+tSU)/T (5)
Wherein, T is light modulation cycle (T=1/FDim), tD be from the DIM rising edge of a pulse to the delay first pulse of power supply FET, tSU is the LED electric current from zero rise time that rises to required electric current, tSD is the fall time of the trailing edge from the DIM pulse equalling zero to the LED electric current.
Serial light adjusting circuit 1222 is that switch mosfet pipe Q2 and LED are cascaded, and the LED electric current will be carried out along with the turn-on and turn-off of tandem tap from the switching between IF and zero like this.The PWM light modulation can adopt a plurality of different circuit to realize the on/off switch of LED forward current, and except that serial light adjusting circuit 1222, the most frequently used scheme enables light modulation (Figure 14), parallel light modulation (Figure 15).As shown in figure 14, in enabling the light modulation scheme, the ON/OFF of LED electric current is by being arranged to switching regulator or power supply fet driver to enable (Enable) or lost efficacy (Disable) realizes; As shown in figure 15, parallel light modulation is that shunting switch mosfet pipe and a LED are connected in parallel, in case this switching tube is arranged to OFF or ON, has electric current I F at once and flows to or flow out LED, thereby change LED forward current mean value realization light modulation.
