Solar Night Lamp Problem

Attach a solar panel to an LED and a battery.

Pretty difficult

You have not explained much about what you have....

You must have a battery. You have a lamp, turned on by "no-daylight" AND movement detector usually infra-red PIR. Probably battery charged by solar panel, but solar panel can double as light detector.

Diagram above is about simplest way such a system could work.

1. The FET acts as a switch for the lamp. It will switch on if voltage at its input, at left, is more than 4 volts. Resistor Rf will put the FET ON, unless something connects FET input to negative (-).
2. During day, transistor L is turned on by high voltage from solar panel using zener diode Z, which conducts only above a certain voltage - no voltage in dark. In day FET & lamp are off.
3. At night L is off, but movement detector PIR transistor P must also be off for FET to switch on - so lamp will come on with movement.

If it is really so simple, then cutting wire "y" from PIR will get what you want. Cutting wire from PIR to + positive supply would probably work as well.

Try to cut wires where you can easily reconnect them by stripping insulation & twisting ends together - resolder if you can.

Let us hear how you get on....

Popular type of detector - extreme left of diagram - in 3 lead TO5 cylindrical housing can be disabled by shorting two pins circled together; that is the two pins which are not connected to positive supply.

Most of these type lights have a high/low mode of operation and cannot sustain the high output for very long under the best circumstances...so you're probably going to need a bigger solar collector and larger battery, easier to just buy the proper light for your purpose...

The top of the line PWM charge controller I purchased for under $10 has a "continuous" output. It shuts off if the battery voltage drops below 10.2 VDC.

Walmart sells this type of light for a couple bucks. They must be available somewhere else.

If you want a light that lights your entire yard, get this. I have this model and it IS bright!

Telepole Manufacturing Inc New Solar Flagpole Light - 120 LED Lights with 800 lumens and up to 10+ Hours of Light $98.00

Less expensive models are available, like this one that can be hanged on a post.

The sensor detects movement, try a piece of Gaffa tape over the sensor.

Then it will never come on!

Walkway lights do what the OP wants, for a few dollars each, usually sold in sets of 4 or more.

Just put one of these in front of it. _{Probably not solar though...}

Why not just send it back and return to have it replaced by a “dusk-to-dawn lights” instead of what you received which is apparently a “motion sensor” light..

It will be a lot easier and possibly cheaper to do..
