本实用新型涉及一种利用自然光的明暗度自动接通和延时关闭霓虹灯、广告灯箱、公共场所照明灯等电源的光控延时开关,以实现无人操作管理。 The present invention relates to a brightness of natural light and automatically turn off the light control delay neon signs, advertising boxes, public lighting lamp power delay switch, in order to realize unmanned operations management.

现有的光电控制开关一般分为两类:一种是人工设定光控开关,它们在使用时需靠人按动起动按钮,开关才能起作用,而另一类为自动光控通断开关,该开关在黑夜接通,当天亮后才能断开,虽然这种开关已实现了无人操作管理,但往往有许多灯具,例:霓虹灯、广告灯箱、公共场所的照明灯等。 Conventional photoelectric switches are generally controlled divided into two categories: one is the manually set light control switch, they require person push on the start button, a switch in use in order to work, while the other is the automatic light control on-off switch the switch is turned on in the night, before dawn when turned off, although this switch is achieved unmanned operation management, but there are often a number of lamps, for example: neon lights, advertising light boxes, lighting and other public places. 它们只需在夜间点数小时,当夜深人静时即可关闭灯的电源,然而上述的开关都不能起到这种作用。 They only point at night hours, late at night when the power of the lamp to turn off, however, the above switching can not play this role.

本实用新型的目的在于提供一种自动光控延时通断开关,它不仅能在夜间自动接通灯具的电源,而且还能根据需要延时数小时后自动关闭灯具电源。 Object of the present invention to provide an automatic light control delay on-off switch, it can not only automatically powered lamps at night, but also automatically turn off the power lamp hours as needed after the delay.

本实用新型所提供的光控延时开关由电源电路、光控电路、执行电路组成,该开关主要是在光控电路和执行电路之间增设了延时电路,该延时电路的输入端接在光控电路的电阻R3上,延时电路的输出端与执行电路的输入端相连。 The present novel optical control delay switch provided by the power supply circuit, control circuit, a circuit performing the switching between the main circuit and the light control circuit performs addition of the delay circuit, the delay circuit input terminal in the light control circuit of a resistor R3, an output terminal connected to the input of the execution circuit and delay circuit.

下面结合附图详细说明本实用新型的具体结构及原理。 The specific configuration of the present invention and the principles described in detail below in conjunction with the accompanying drawings.

图1——是本实用新型的方框图图2——是本实用新型的电原理图图3——是图2之第一种实施例示意图图4——是图2之第二种实施例示意图图5——图2之第三种实施例示意图如图1、图2所示,本实用新型的电源电路包括全桥QL、稳压管DW、电容C1、C2、电阻R1,220V交流电经C1降压,全桥QL整流,电容C2滤波,DW1稳压后输出的工作电压以供给光控电路(2)、延时电路(3)和执行电路(4)工作,光控电路(2)由三极管V1、光敏电阻RG、电阻R2、R3组成,延时电路(3)包括三极管V2、V3、二极管D5、电阻R5、R6及电容C3。 FIG 1-- is a block diagram of the present invention according to the present invention is 2-- electrical schematic diagram of FIG. 3-- 2 is a view of a first embodiment of a schematic embodiment of FIG. 4-- 2 is a schematic diagram of a second embodiment of FIG. FIG 5-- 2 of the third embodiment of FIG. 1 a schematic view, shown below, the present invention comprises a full-bridge power supply circuit QL, DW regulator, capacitors C1, C2, resistor R1,220V AC by a C1 2 buck, QL full-bridge rectifier, filter capacitor C2, the regulated output DW1 operating voltage supplied to the light control circuit (2), a delay circuit (3) and the execution circuit (4) work, light control circuit (2) triode V1, the RG photosensitive resistor, resistors R2, R3 composition, a delay circuit (3) comprises a triode V2, V3, a diode D5, resistors R5, R6 and the capacitor C3. 当白天(有光照时),光敏电阻RG呈低阻值,促使基极连在光敏电阻RG上的三极管V1导通,V1的输出信号经电阻R3耦合至三极管V2的基极,使V2处于截止状态,而电流通过阴极连在V2集电极、阳极与电容C3的正极相连的二极管D5向C3充电,于此同时连在二极管D5阳极上的V3导通,其输出信号经电阻R6送入执行电路的三极管V4基极,执行电路由三极管V4、集成块LM555、连在集成块LM555(3)脚上的继电器J1、电阻R7、二极管D6组成,继电器J1的触点连在负载(灯泡、霓虹灯)与电源之间。 When (when there is light) during the day, the photosensitive resistor RG resistance was low, prompting a base connected transistor V1 on the photosensitive resistor RG is turned on, the output signal V1 is coupled via a resistor R3 to the base of the triode V2, V2 is turned off so that state, and the current collector attached to V2, the diode D5 and the anode connected to the positive electrode of the capacitor C3 to C3 is charged through the cathode, V3 thereto even while diode D5 is turned on anode, which is fed the output signal via a resistor R6 execution circuit base transistor V4, V4 performed by the transistor circuit, the LM555 manifold, manifold attached LM555 (3) feet relay J1, resistor R7, diode D6 composition, even in the contacts of relay J1 load (light bulbs, neon) between the power source. 随着V3的导通V4也导通,连着V4集电极上LM555②、⑥脚呈低电平,由于V1的导通,与V1集电极相连LM555的④脚处于“复位”状态,因而LM555集成块的③脚呈低电平无信号输出,继电器J1不吸合,其触点不动作,负载因断电而不照明。 As is also turned ON V4 V3, V4 collector attached on LM555②, ⑥ pin was low, since V1 is turned on, a collector connected to V1 and LM555 pin ④ in the "reset" state, thus LM555 integrated ③ pin blocks go low no signal output, relay J1 does not pull, which does not contact operation, the load due to power outages without illumination. 当夜幕降临(无光照明时),光敏电阻RG的阻值增大,促使V1截止,V2导通,LM555集成块的④脚“置位”,其③脚由低电平变成高电平,使继电器J1得电吸合,其触点闭合,负载的电源被接通,点亮了霓虹灯,广告灯箱等,由于在V2的集电极与V3的基极连接的二极管D5所起的隔离作用,贮存在C3的电只能通过V3的b、e极缓慢放电,经过若干小时放电后,三极管V4截止,接在V4集电极上的LM555集成块②、⑥脚呈高电平,LM555集成块翻转,其输出端③脚也由高电平转为低电平,J1因失电而释放,其触点断开,负载的电源也断开,从而实现了延时关断负载电源的目的。 When (no light illumination) night, increasing the resistance of the photosensitive resistor RG, prompting off V1, V2 is turned on, the LM555 manifold pin ④ "set", which is a low level to the high level by the pin ③ the relay J1 be energized, its contact is closed, the load power is turned on, neon lights, advertising light boxes, since the diode D5 V2 and V3 collector connected to the base of the role played by isolation , only C3 is stored in the V3 by b, e discharge very slowly, after several hours of discharge, the transistor is turned off V4, V4 connected to the collector of the LM555 integrated block ②, ⑥ pin goes high, the manifold LM555 inverted, its output ③ feet from high level to low level, due to loss of power Jl released, its contacts open, the load power is also turned off, thus achieving the purpose of load power off delay.

本实用新型若只用于控制路灯等夜间接通,白天关闭的长明灯,取消延时电路即可达到。 If only the present invention for controlling the street lamp is turned on at night, daytime long light off, delay circuit cancellations can be achieved.

为了能改变霓虹灯、广告灯、公共场所照明灯等的延时时间的长短,本实用新型在R5与地之间接有可变电阻RP(见图3)。 In order to change the length of the delay time of neon lights, advertising lights, public lighting lamp or the like, the present invention indirectly variable resistor R5 and the ground in the RP (see FIG. 3).

作为本实例的一种变换(见图4),本装置将电磁继电器J2连在三极管V2的集电极与工作电源之间,其触点和降压二极管并联后串接在交流电源与负载之间,当然也可直接将双向可控硅直接串接在交流电源与负载之间,设定时间后降压供电,以达到节约电能,延长灯具使用寿命的效果。 As an example of this conversion (see FIG. 4), the electromagnetic relay device J2 is connected between the collector of the triode V2 of the power supply, and its rear contact buck diode parallel connected between the AC supply and the load , of course, can also be directly triac directly connected in series between an AC power source and the load, step-down power after a set time, in order to achieve energy saving, the effect of extended lamp life.

本实用新型为了在下雨天也能有效地保护设置在露天的霓虹灯、广告箱等,本实施例将湿度传感器P并联在光敏电阻RG的两端(见图5),即可实现白天断开,夜间接通,下雨断开的作用。 The present invention can be in the rain to effectively protect disposed in the open neon signs, advertising boxes, the humidity sensor of the present embodiment will be P photosensitive resistor RG is connected in parallel (see FIG. 5), to achieve disconnection daytime, nighttime turned off rain effect.
