2020/12/30· I want to use a single white LED (or a single 5050 RGB strip light LED) to backlight the lithograph. Normally, I could use a solar powered Garden light circuit, however I need it to stay lit during the daytime AND night time and still charge a battery (1.2V NI-CD) for the nighttime use.
I have one solar light that will not turn off in the daylight. There doesn't appear to be anything obstructing the sensor. The rechargeable batteries are being completely drained and will not recharge when in this particular light. I can recharge the batteries using a battery charger.

2013/10/03· By installing solar street lights in the Capital city Islamabad of Pakistan, it will help to reduce the energy problem in some way. The installation cost of Solar Street light is less than the Traditional Street light. So, by installing Solar Street lights, it will definitely play a pivotal role to stabilize the economy of Pakistan.
Light- Light Dependent Resistor (LDR), Relay and Light emitting emitting diodes are elements for light signalization in electronics. diodes (LEDs) which we are using in place of a light bulb. By using this project as the basic principle we can design centralized intelligent system for the perfect usage of streetlights A. 555 Timer IC in any place.

The working principle of LDR is that it gives less resistance in high light intensity and high resistance in low light intensity (ie) it gives high resistance in dark or night and low resistance in day or light. Here we use transistor as a two way switch. If the voltage through base is …
The solar street light extent of supply will comprise the structure, creation of materials, assembling, drawings & information, painting, assembly, testing, examination plus all as per relevant codes and norms also any extra prerequisites of this detail, the solar road light works from Dusk to Dawn namely., the lamp automatically turns ON after
When it is dark, the photocell has high resistance, so no current flows through the base and the relay is not activated -- the light is on. In a real street light the circuit might be a bit more advanced, but not a lot. It has the CdS cell, the transistor and the relay, but might need more than one transistor depending on the size of the relay.
