1.1 Introduction
Solar powered security lighting system is a raised source of light on the edge of a road, environment or community which is turned on or lit at a certain time every night.
Security lights are one of the most practical and effective ways to prevent crime in or around their home or office. Infact statistics show that a well lighted property cannot prevent malicious activity or guarantee personal safety, but crimes are les likely to occur because lighting is an excellent deterrent.
A security lighting system is a deterrent because it exposes the criminals making them feel vulnerable and insecure. Criminals most likely look for areas with little to no lighting for obvious reasons.
Home owners on the other hand, can benefit from a lighting security system that can detect and recognize movement in an otherwise overlooked and dark surrounding downward directed and shield security lighting of medium intensity provides the best vision for outdoor lighting. In addition to the position of the security lights, controlling the glare is a major consideration.
This is crucial because home owner who can see the criminal can possible provide authorities with descriptions information and other valuable clues.
There are many types of security lighting and outdoor security system on the market today. To help you better understand the differences it is best to divide security lighting into two basic lamp categories.
HID and Halogen or Incandescent as follows:
HID Or High Intensity Discharge: HID light sources are designed to operate by using magnetic or electronic ballasts in combination with a gas filled lamp. The purpose of the ballast is to convert the supply voltage to a high operating voltage necessary to excite to gas in the lamp creating the light.
Everyone is familiar with mercury vapour lighting. These are the blue-green coloured security lights you have seen way up tree tops, or perhaps attached to your neighbor's house other types of outdoor flood lighting, include metal halide, high pressure sodium, and fluorescent. With the exception of fluorescent, all of these sources require a warm-up period and a re-strike time to return to full intensity should be power go off.
They are not designed for instantaneous use and should be supplemented by other sources for panic or spontaneous lighting. High intensity discharge products are energy efficient, long lasting an d very commonly use din land use lighting.
Halogen or incandescent light sources: Halogen fixtures are designed to operate on standard house current. These light bulbs contain a carbon filament suspended on several supports within the lamp envelops which glow when current is passed through the lamp. These lights which your see on everybody's house are perfect for continuous or instant tenuous use because they require no warm up period. These security lights produce a white to yellow colour and are less desirable for aesthetic lighting application. These lights do work well in combination with tree lighting or moon lighting jobs as supplemental security lighting.
Another tool commonly used in security lighting is motion detectors or occupancy sensors. These hardy devices turn the security lights on and off when motion or movement is detected maxing them ideal for security lighting and energy management. Because they are constantly switching the lights OFF and ON the lights, they cannot be used to control high intensity discharge source. They are perfect for controlling halogen or incandescent source. It is important to position your security lights out of arms reach so that they cannot be disabled or destroyed by intruders. Remember, the best position is a downward position, so mount them as high as possible on your home, office, or community for safe, reliable operation.

A rough sketch on how the project would look like was first draw, detailing all the components blocks that would make-up the complete system. Once drawn and checked for consistency we proceeded to the second phase.
