Request for a design of a bright solar-powered yardlight with LEDs. Answered
We live in a neighborhood without street lights. Each homeowner is required have a automatic light on a pole in the middle of the front yard. These lights are powered by a 120 volt line running underground. These lights are constantly failing because of the shoddy way they laid the line just under the sod.
My solution was to replace the light head with a solar light fixture that I purchased from Menards for $68. It has 12 LEDs, small solar panels on top facing in four directions, and interior mirrors to enhance the reflection. The problem is that it is barely adequate. I would have preferred to use the old fixture and outfit it with a brighter set of LEDs. It would be great if someone could come up with a simple plan for something like this.
I would like to have 24 LEDs (I could cannibalize these from an LED flashlight), a chain of small solar panels taken from solar yardlights, rechargeable batteries, and a compact circuit that would sense darkness (possible reused from a yardlight). I will worry about mounting the solar panels outside the fixture. Note: this cannot be an 'accent light'. It should have the output of at least a 20 watt incandescent bulb).
