Intro: Make a Solar Powered Led Lamp Post Light
This is my first instruct-able so bear with me, i will show you how to Make a Solar Powered Led Lamp Post Light, it will light up a large part of your yard. i have a similar light for sale on ebay at this link http://www.ebay.com/itm/400387635748?ssPageName=STRK:MESELX:IT&_trksid=p3984.m1555.l2649
Step 1: What You Will Need
1-5 watt 12 volt solar panel, 1-6" white glass globe, 1-48 led light panel, 1- pvc 3" to 1-1/2" reducer, 1-piece of steel strap 18" long, 2-pieces of aluminum angle, 1- 12 volt battery pack, 1- dusk til dawn auto light switch, speaker wire, soldering iron, solder, glue, wire strippers, heat shrink tube.
First glue the battery pack to the back of the solar panel, make sure the solar panel has a diode, if not then add one to the pos. wire, the silver end of the diode is power out to the battery, put a 1" piece of shrink tube to all wire connections before you connect them as you can not do it after connecting them, solder all connections and heat the shrink tube to seal the connections, connect the wires from the panel to the battery [pos. to pos. and neg. to neg.] also connect the light sensor in wires to the battery pack, then connect a piece of speaker wire to the out wires from the light sensor.
now take your reducer and drill a small hole for the wire coming from the light sensor to come into it. glue some blocking inside the bottom of the reducer to mount the light panel to[ after testing i found that a 24 led light panel works better than the 48 led panel, it will run longer], i used a peanut butter jar lid and a light socket for blocking. glue the light panel to the blocking, when the glue [shoe goo] is dry[over night] run the wire from the light sensor in through the hole and cut some 1" pieces of shrink tube on the wires before you connect them, connect the wires and solder them, make sure you connect pos. to pos. and neg. to neg. ,with a lighter heat the shrink tube to seal the connection,
apply a layer of silicone to the top edge of the reducer and place the glass globe on top and press it into the silicone, let it set over night, dig a hole about 18" deep where you are going put the light, place a 7 foot lenght of 3" pvc into the hole and fill with dirt and pack it, drill 2 1/4 holes at each end of the strap, bend the steel strap around the post into a u shape and screw it to the post, drill a 1/4" hole in the middle of each angle, glue or bolt the 2 aluminum angles to the solar panel the same distance apart as the width of the u shaped steel strap, bolt on the panel with 2 1/4" bolts with wing nuts.
glue the light on top of the post, make sure the panel is aiming south, it should turn on at dusk and off at dawn. i have a similar light for sale on ebay at this link http://www.ebay.com/itm/400387635748?ssPageName=STRK:MESELX:IT&_trksid=p3984.m1555.l2649
