The specific embodiment
, in order to more fully understand technology contents of the present utility model, below in conjunction with specific embodiment, the technical solution of the utility model is further introduced and explanation, but be not limited to this.
As shown in Fig. 1-6, a kind of flicker type LED of the utility model light-emitting device, comprise power module 10 and 20 LED lamp pearls 20 that are connected with power module 10; Also comprise 10 drive circuits 40 being located between power module 10 and 20 LED lamp pearls, and the microcontroller 30 that is connected with 10 drive circuits; Microcontroller 30 also is connected with light sensor 31(photodiode D21 as shown in Figure 2); Microcontroller 30 is provided with 10 control signal outputs, controls respectively 10 triodes.Also comprise the plucking number sign switch 33 that is connected with microcontroller.Power module 10 comprises the first output 11 that is connected with microcontroller 30 and the second output 12 that is connected with each drive circuit.
In the present embodiment, microcontroller 30 is the N79E81XAT20 cake core, and drive circuit 40 is triode (Q2-Q11 as shown in Figure 2), and LED lamp pearl 20(is D1-D20 as shown in Figure 2) comprise red LED lamp pearl, green LED lamp pearl and blue led lamp pearl.Each transistor circuit is connected with the LED lamp pearl of two series connection, drives two LED lamp pearls.Also comprise the burning interface 32(that is connected with microcontroller 30 J1 as shown in Figure 2).Also comprise back casing 51 and protecgulum 52, the inboard of protecgulum 52 is provided with lamp plate 53, and lamp plate 53 is provided with 20 LED lamp pearls, and protecgulum 52 is provided with and 20 transparent areas 521 that LED lamp pearl is corresponding.Transparent area 521 is provided with 16X18 optically focused convex part 522, to realize luminous the diffusion uniformly to 20 LED lamp pearls.
In order to have larger drop shadow spread, transparent area 521 is evagination circular arc, and lamp plate 53 is also evagination circular arc.Back casing 51 wherein is with protecgulum 52 for clamp-close type is connected, and the inner chamber of back casing 51 is provided with for the fixing circuit board 54 of microcontroller 30, power module 10 and drive circuit 40.
Wherein, plucking number sign switch is divided into 4 gears, is respectively, complete bright gear, and 4 hours gears, 8 hours gears, and complete shut-down state,
Select needed gear by toggle switch.
Complete bright gear: complete when toggle switch was selected bright gear, corresponding IO mouth was dragged down, after microcontroller detects, duty is set to complete bright state, this state no matter be daytime or evening lantern festival work always;
4 hours gears: when being set to 4 hours gears, after detecting, microcontroller is set to 4 hours states, because the photosensitive tube on plate can cause because of the light and shade of light the variation of resistance own, we convert the variation of voltage to by peripheral circuit, and by the IO mouth value that reads level (about every 500MS reads once) regularly, when the level value that reads continuously 50 times all is 1 or 0, the corresponding current state of software is set to daytime and evening, when being set to the evening back light, state starts working, timer starts timing simultaneously, software is put lamp work position of rest 1 when timing to 4 hour, lamp quits work, this lamp position of rest clear 0 when state is daytime, but in the time of by day except complete bright gear, lamp during other gears is not worked,
8 hours gears: timing time is 8 hours, and other are identical with 4 hours gears;
The complete shut-down gear: all lamps of this gear all do not work.
Gear shows: the lantern festival during toggle switch on panel shows gear accordingly, and when complete bright state, all lantern festivals are bright, and during 4 hours gears, blue lantern festival is bright, and red light can be bright in 8 hours, and the complete shut-down state does not show.Lantern festival does not show range state always in working order the time, can show first in the time of in working order that gear is carrying out work.
The duty of lamp: every two lamps of all 20 lamps of this plate are one group, and to receive MCU(be microcontroller) 10 IO mouths on, during work, all IO mouths can be simulated PWM output, recently control the display effect of every group of lamp by adjusting duty.
In other embodiment, plucking number sign switch also can make a plurality of control buttons into.The transparent area of protecgulum and lamp plate also can be adopted planar structure; Also can adopt LED lamp pearl and the drive circuit of other quantity; Also can adopt the drive circuit of other form; Light sensor also can adopt photo resistance; Also can increase the white led lamps pearl.
In sum, the utility model is owing to having a plurality of LED lamp pearls, a plurality of control signal ends by microcontroller, the different light colors that can send, brightness also can change at random, and can make flicker and the special efficacy such as wave, be incident upon on windowpane or printing opacity curtain, can simulate the television set effect of shadow.See up outside window from room, can see that indoor light is flickering, picture shakes suddenly texts, just as there being the people seeing TV.Effect correspondence by this flicker is formed with the people in the indoor illusion of seeing TV, reaches and prevents that the thief from entering the purpose of indoor theft, and the effect that frightens thief's resistance thief is arranged.Because LED lamp power consumption is very low, also power consumption is few completely so whole light-emitting device works long hours; Adopted light sensor, automatically the sensitization dormancy.Optical inductor detect day dim or darkness after Auto Power On.Machine can all weather operations, also can set timing working after darkness.
Above-mentionedly only with embodiment, further illustrate technology contents of the present utility model; so that the reader is easier to understand; but do not represent that embodiment of the present utility model only limits to this, any technology of doing according to the utility model is extended or recreation, all is subjected to protection of the present utility model.Protection domain of the present utility model is as the criterion with claims.
