Description

技术领域technical field

    本实用新型涉及LED光源,具体涉及一种自控节电型LED照明灯,主要适用于车库及巷道、隧道等特殊环境的节电照明。The utility model relates to an LED light source, in particular to a self-controlled power-saving LED lighting lamp, which is mainly suitable for power-saving lighting in special environments such as garages, roadways, and tunnels.

背景技术Background technique

由于地下车库需要昼夜24小时照明,长年累月耗电费钱,光源也易损坏,从节约电能降低开支出发,人们一直在做多种尝试,现在一些车库已将原40W/根的T8日光灯改换为28W/根的T5节能日光灯,虽然增加了一些投入,但确能是收到一定的节电省钱的效果,也有些地下车库开始尝试采用更为节能的LED日光灯,其耗电在14W/根左右,节电效果更好,但造价太贵,节电不省钱。新近有将LED照明灯配装声光控开关进行节电控制,节电效果更显著,但因造价高,且会使车库在无声响情况下出现黑暗状况而不安全。Because the underground garage needs 24 hours of lighting day and night, it consumes electricity for many years and is expensive, and the light source is also easily damaged. From the perspective of saving electricity and reducing expenses, people have been making various attempts. Now some garages have replaced the original 40W/root T8 fluorescent lamp with 28W. Although the T5 energy-saving fluorescent lamps per root have increased some investment, they can indeed achieve a certain effect of saving electricity and money. Some underground garages have begun to try to use more energy-saving LED fluorescent lamps, and their power consumption is about 14W per root. , the power-saving effect is better, but the cost is too expensive, and power-saving does not save money. Recently, LED lights are equipped with sound and light control switches for power saving control, which has a more significant power saving effect, but because of the high cost, it will make the garage appear dark and unsafe without sound.

该自控节电型LED照明灯的工作原理如下:The working principle of the self-controlled energy-saving LED lighting is as follows:

市电220V交流输入经保险电阻R0连接DBI全波桥式整流器,全波桥式整流器输出的100HZ正弦半波一路经电阻R1,R2,R7,R18降压,稳压管DW1,DW2稳压,电容C1,C2滤波,获得两组低压稳压电源,另一路为LED光源负载提供高压电源;V-F转换电路3与驱动输出管Q1、Q1`、电流取样电路6连接构成的恒流源电路核心器件是基准电压源U1及电容C6,分压电阻R4,R5及取样电阻R6,调整R6可获得不同的恒流值,其控制过程是取样电阻R6将流过LED光源负载的脉冲电流转为电压,经电容C7滤波后,送基准电压源U1转换为脉频控制驱动输出管Q1、Q1`的通断,当电压大于基准电压时基准电压源U1导通强制将驱动输出管Q1、Q1`关掉,而取样电阻R6一旦无电流,基准电压源U1又使驱动输出管Q1、Q1`导通,由于电容C6的延迟使基准电压源U1反复的通断,当交流电网的电压变高或变低使流过LED光源的电流增加或减少,导致基准电压源U1控制驱动输出管Q1、Q1`的关断时间缩短或延长,从而达到调节电流使其恒定的目的。The mains 220V AC input is connected to the DBI full-wave bridge rectifier through the insurance resistor R0, and the 100HZ sine half wave output by the full-wave bridge rectifier is stepped down by resistors R1, R2, R7, and R18, and the voltage regulator tubes DW1 and DW2 are stabilized. Capacitors C1 and C2 filter to obtain two sets of low-voltage regulated power supplies, and the other provides high-voltage power supply for the LED light source load; V-F conversion circuit 3 is connected with drive output tubes Q1, Q1` and current sampling circuit 6 to form the core component of the constant current source circuit It is the reference voltage source U1 and capacitor C6, voltage divider resistors R4, R5 and sampling resistor R6. Adjusting R6 can obtain different constant current values. The control process is that the sampling resistor R6 converts the pulse current flowing through the LED light source load into a voltage. After being filtered by the capacitor C7, the reference voltage source U1 is sent to the pulse frequency to control the on-off of the drive output tubes Q1 and Q1`. When the voltage is greater than the reference voltage, the reference voltage source U1 is turned on and the drive output tubes Q1 and Q1` are turned off. , and once the sampling resistor R6 has no current, the reference voltage source U1 turns on the drive output transistors Q1 and Q1`, and the reference voltage source U1 is repeatedly turned on and off due to the delay of the capacitor C6. When the voltage of the AC power grid becomes high or low The increase or decrease of the current flowing through the LED light source causes the reference voltage source U1 to shorten or prolong the turn-off time of driving the output transistors Q1 and Q1`, thereby achieving the purpose of regulating the current to keep it constant.

当环境光较强时光敏电阻CDS感受光照,开关管Q2饱和导通,驱动输出管Q1、Q1`栅极无电流被强制关断,LED光源负载不亮。当环境光弱时,开关管Q2断开,由恒流源输出设定的较小的恒流电流值,即LED光源发出较弱的光,一旦人车来去发出一定强度的声响,开关管Q3解除允许拾音器M1的信号输出,拾音器接受到声响信号,达到调定的强度,迅速使开关管Q4变低,由于储能电容C7上的电压不能突变,即给开关管Q5施加一个反偏电压强制其关断并开始延时,延时时间的长短主要由C7,R17决定;与此同时复合开关管Q6,Q7接通电阻R9,使其并联在取样电路R6中,以增大恒流电流值,使LED光源获得更大的恒流电流,即获得更亮的光照。一旦延时结束,复合开关管Q6、Q7关闭,电阻R9断开,恒流电流回复到原较小的电流,即在无人无车发出声响且环境光较弱时,照明灯发出弱光,有车发出声响的有限时间内照明灯发出亮光。When the ambient light is strong, the photosensitive resistor CDS feels the light, the switch tube Q2 is saturated and turned on, the gate of the drive output tube Q1 and Q1` has no current and is forcibly turned off, and the load of the LED light source is not bright. When the ambient light is weak, the switch tube Q2 is disconnected, and the smaller constant current value set by the constant current source output, that is, the LED light source emits weak light. Q3 is released to allow the signal output of the pickup M1, the pickup receives the sound signal, reaches the set strength, and quickly lowers the switch tube Q4, because the voltage on the energy storage capacitor C7 cannot change suddenly, that is, a reverse bias voltage is applied to the switch tube Q5 Force it to shut down and start to delay. The length of the delay time is mainly determined by C7 and R17; at the same time, the composite switch tubes Q6 and Q7 are connected to the resistor R9, so that they are connected in parallel in the sampling circuit R6 to increase the constant current. Value, so that the LED light source obtains a larger constant current, that is, obtains brighter light. Once the delay is over, the composite switching tubes Q6 and Q7 are turned off, the resistor R9 is turned off, and the constant current returns to the original smaller current, that is, when there is no sound and the ambient light is weak, the lighting will emit weak light. The lights will be on for a limited time when there is a car sounding.
