in fact you can this circuit for implementing any type of automatic night light. the circuit uses a light dependent resistor (ldr) to sense the light .when there is light the resistance of ldr will be low. so the voltage drop across pot r2 will be high.this keeps the transistor q1 on. the collector of q1(bc107) is coupled to base of q2(sl100).
2017 11 21 solar light circuit. circuit diagram of the solar garden light is shown in fig. 1. it is built around a solar lamp controller ic cl0116 (ic1), a miniature solar cell, a bright white led (led1) and a few other components. fig. 1 circuit diagram of solar garden light solar powered led street light with auto intensity.
mar 16, 2018 we previously made many circuits using ldr, which use ldr to automate the lights according to requirement.. working of ldr controlled led using arduino. as per the circuit diagram, we have made a voltage divider circuit using ldr and 100k resistor. the voltage divider output is feed to the analog pin of the arduino.
solar street light project report pdf download windows 7 64 bit .. solar powered led street light with auto intensity control. because, this solar powered street light can conserve a large amount of electricity compared to the other lights which are a light to their maximum intensity at all times after they are turned on solar powered led
this meter shows the output amps from the solar panel array. the simulator uses 8 solar panels rated at 100 watts each for a total output of 4 kilowatts based on an average solar day of 5 hours. 800 watts times 5 hours equals 4000 watts or 4 kilowatts (4kw). the meter will display 0 amps to 56 amps in 8 amp increments.

this diagram illustrates the connectivity of a typical solar power kit, including a solar panel, a solar charge controller, a battery and the load (e.g. a light bulb). the solar panel connects to the controller through positive and negative leads, only creating a charging function when the controller
power source and a 12v 2w led as light source. to charge the battery i am using 12v 6w solar panels. to reduce the cost i am using a dc to dc buck converter as charge controller. it can boost 12v to 14v and prevent reveres flow of voltage with a high capacity diode. you may wonder how this circuit work without any overcharge protection
hid presently used for urban street light are based on principle of gas discharge, thus the intensity is not been controllable by any voltage reduction method as the discharge path is broken. disadvantages of existing system hid lamps consume more power. the life time of the hid lamps is very less.
