To shown in Figure 5, the multi-functional dimmable lamp of the LED of the utility model comprises lampshade, LED lamp pearl panel, stepper motor, master control circuit board and infrared wireless remote control device like Fig. 1.
Lampshade is inside and outside cavity configuration, and inner chamber 12 is the column structure of 5cm for radius, and an end of lampshade inner chamber 12 is made up of six spherical structures, and the diameter of each sphere is 10 ~ 20 millimeters, and its distribution map is as shown in Figure 3.These six spherical spheres are circumscribed mutually, and internal face scribbles specular material to beam projecting direction one side, can inner chamber LED lamp pearl 4 issued lights that place the sphere focus be reflected into parallel light emergence.As shown in Figure 4.Exocoel 13 is the terrace with edge structure, when light fixture is operated in area illumination, helps the diffusion outgoing of light.What adopt in the junction in inside and outside chamber 12,13 is the helicitic texture of machinery, and promptly inner chamber 12 is carved with external screw thread, and exocoel 13 is carved with internal thread.This screw connection structure easy accessibility helps the installing/dismounting of light fixture.
Two kinds of light illumination modes of the multi-functional dimmable lamp of this LED are to realize through the LED lamp pearl panel of exocoel in controlling.Specifically, utilize spherical structure that light is had the effect of converging, when unlatching was positioned at inner chamber LED lamp pearl 4, light reflected through the spherical structure of the high emission coefficient that lampshade inner chamber 12 is coated with, along the parallel outgoing of lumen shaft.Under this directional lighting pattern, the beam radius that light fixture sent is less, has very big energy, and brightness is higher, and needs carry out the special illumination in part to certain zonule in being fit to live.When only opening lampshade exocoel LED lamp pearl 5, or during LED lamp pearl 4,5 standard-sized sheets of inside and outside chamber, light fixture is operated in the area illumination pattern.Light under the area illumination pattern relatively disperses, evenly, brightness is less, is fit to lighting of home at ordinary times.Two kinds of light illumination modes can be changed fast, have satisfied the lighting demand of general lighting and special occasions.
The adjusting of the illumination angle of the multi-functional dimmable lamp of this LED is respectively horizontal plane through two rotational planes and the vertical plane stepper motor is realized.As shown in Figure 1, the rotational plane of horizontal plane stepper motor 9 is a horizontal plane, and the rotational plane of vertical plane stepper motor 10 is a perpendicular.At first, stepper motor is to change electric impulse signal into the angular displacement device.Under the situation of non-overload; The frequency and the umber of pulse of pulse signal only depended in rotating speed of motor, the position that stops; And do not receive the influence of load variations, when step actuator receives a pulse signal, it rotates a fixing angle with regard to drive stepping motor by the direction of setting; Be step angle, its rotation is to move step by step with fixing angle.The multi-functional dimmable lamp of this LED is to export pulse number through the serial ports of the main control chip of control circuit board to come the pilot angle displacement, thereby reaches the purpose of accurate location.And stepper motor has multiple asynchronous elongation to select, and can select the stepper motor of asynchronous elongation according to the size of the needed angle of each rotation.Because the low rotation that can't drive stepping motor of the serial ports voltage pulse output of main control chip is so employing ULN2003 chip 8 is as chip for driving.Make the serial ports output signal of main control chip 2 when overdriving ULN2003 chip 8, obtain amplifying, thus the rotation of drive stepping motor.
The master control circuit board of the multi-functional dimmable lamp of LED of the utility model is by MCS_52 chip 2 and corresponding crystal oscillator 1 thereof, CD4066 analog switch chip I 7, and CD4066 analog switch chip II 3, ULN2003 chip for driving 8 and infrared receiving terminal are formed.As shown in Figure 5.
MCS_52 chip 2 is being controlled all functions of this light fixture, and its serial ports output provides the enable signal of each function.It is timer 0 and timer 1 that MCS_52 chip 2 has carried two 16 timer.When timer overflows, can send interrupt requests, open under the condition of interruption, regularly interrupt just can in time being handled timed events in case quilt responds from trend CUP.These two timers can be controlled the mode of its work through program.The maximum timing time of variety of way is different.The various combination of the register R0 ~ R7 that carries with MCS_52 chip 2 through these two timers can be realized the timing of random time within the specific limits.The crystal oscillator frequency of MCS_52 chip 2 is 12MHZ, so its each instruction cycle is 1us.With time of required timing divided by the instruction cycle resulting be exactly to import the timing number that single-chip microcomputer needs.
CD4066 analog switch chip I 7 realizes the switching of lamp lighting mode through the light on and off of the inside and outside chamber of control LED lamp pearl.CD4066 analog switch chip II 3 has four independent switches, and is as shown in Figure 6.The state of each switch all is to be controlled by enable signal separately.CD4066 analog switch chip II 3 reaches the brightness of control LED lamp pearl through the resistance of control LED lamp pearl series connection thereby control the electric current that flows through LED lamp pearl.
ULN2003 chip for driving 8 has four, and independently passage can amplifying signal, and is as shown in Figure 7.Can select different passages according to different needs.For the four phase step motor that the multi-functional dimmable lamp of this LED is selected for use, need four input signals to control its step thereby select four passage amplifying signals such as 1B1C, 2B2C, 3B3C, the 4B4C of ULN2003 chip for driving 8 arbitrarily.
The infrared remote control module of the multi-functional dimmable lamp of this LED is formed by transmitting and receiving the two large divisions.Radiating portion comprises keyboard matrix, coded modulation, LED infrared transmitter; Receiving unit comprises light, electric switching amplifier, demodulation, decoding circuit.When the different key of infrared remote controller was effectively pressed, remote controller just sent a series of different remote control modes.And hot outer when receiving termination and receiving different remote control modes, be demodulated into different control informations.These information pass to single-chip microcomputer, realize different functions by chip again.Infrared remote control has solved the inconvenience of traditional hand switch, has realized non-contact control within the specific limits.Infrared remote controller has also that volume is little, low in energy consumption, function is strong, low cost and other advantages.
The adjusting of illumination angle of the present invention:
At first, the original state of setting light fixture be exocoel in the light fixture axis straight down, the center of vertical plane stepper motor 10 is initial point 0 point of 3-D walls and floor, the axis of horizontal plane stepper motor 9 overlaps with the z axle.If the A point is positioned at the lampshade inner chamber upper surface center of circle, the B point is the lampshade exocoel terrace with edge lower surface center of circle, and promptly AB is the axis of exocoel in the lampshade, and it is as shown in Figure 8 that then the spherical coordinates of BA is expressed as (r, 90 °, 0 °).
If give main control chip MCS_52 chip 2 certain telecontrol code through IR remote controller, its decoded signal is to make two pulses of serial ports output that connect horizontal plane stepper motor 9.Output to horizontal plane stepper motor 9 after then ULN2003 chip for driving 8 two pulse signals that will receive amplify, make horizontal plane stepper motor 9 rotate counterclockwise two stepping angles.What the multi-functional dimmable lamp of this LED was selected for use is four phase step motor, and the rotation of software set stepper motor is four phases, eight bats, and the step angle of stepper motor is 7.5 °.Thereby two pulses make horizontal plane stepper motor 9 be rotated counterclockwise 15 °, and then horizontal plane stepper motor 9 drives vertical plane stepper motors 10 and in horizontal plane, is rotated counterclockwise 15 ° with whole lampshade, and just, BA is that (r, 105 °, 0 °) is as shown in Figure 9; If then vertical plane stepper motor 10 is to be rotated counterclockwise 15 ° signal again, then BA is (r, 105 °, 75 °), and is shown in figure 10.
The conversion of light illumination mode of the present invention:
Light fixture is operated in the area illumination pattern when supposing beginning, owing to need existing the need that it is switched to the directional lighting pattern.When light fixture was operated in the area illumination pattern, the SWA and the SWB of CD4066 analog switch chip I 7 all were in closure state.Give main control chip MCS_52 chip 2 signals through IR remote controller, the SWA enable signal of CD4066 analog switch chip I 7 is not enabled, then SWA breaks off, and the LED lamp pearl of lampshade exocoel is changed into by luminance extinguishes state.So just realized from of the switching of area illumination pattern to the directional lighting pattern, if from directional pattern to the switching of area illumination pattern then so long as negative actuation get final product.
The adjusting of lamp brightness of the present invention:
Suppose that the SWB that sets initial equilibrium state CD4066 analog switch chip II 3 through software program is in closure state, SWA, SWC, SWD are in off-state, and the electric current that flow through LED lamp pearl this moment is about Vcc/R12, and the luminous power of establishing this state is p0 (lumen).If the illumination in room diminishes; Need transfer the brightness of lamp big; Then can give signal a of main control chip through remote controller; The a signal makes the P1 serial ports output signal b of main control chip, and the SWA of b signal controlling CD4066 analog switch chip II 3 is in closure state, and other switches are in off-state.So just feasible resistance of connecting becomes R11 by R12, and (R11＜R12), it is big that electric current becomes, and LED lamp pearly-lustre power becomes greatly, and brightness brightens.(with reference to Fig. 5)
Sum up, it mostly is that drive through lever or gear realizes that the illumination angle of traditional light fixture is regulated.Degree of regulation by lever drives is low, and it can't accomplish to control accurately the illumination angle of light fixture.The adjusting of the illumination angle that is driven by the rotation of gear can only be regulated by the implementation space bidimensional, can't reach space illumination adjustments at any angle.The multi-functional dimmable lamp of LED provided by the present invention has then overcome the shortcoming that traditional illumination angle is regulated.Simultaneously, the present invention is through the inside and outside chamber design to lampshade, the multiplex (MUX) who has realized light fixture directional lighting and area illumination pattern; The timing function of mating circuit; Can realize the time switch of random time within the specific limits, realize that illumination is intelligent, and practiced thrift electric energy.
