LED sign lighting provides years of illumination and low energy costs. sign modules that consume 50mA of power each. Required materials differ depending on sign size, module size, length of wire between modules, current draw, and lumen output.

Materials:

1. First, measure your sign. Although we recommend spacing module rows 3 inches apart, it’s ultimately up to you. If you want a brighter sign, place them closer together and vice versa for a dimmer sign. With the recommended 3-inch spacing, a 4-foot square sign would need 150 modules (15 rows of 10). Again, the quantity of modules needed  is based on many factors and can differ.

These LED sign modules are available in custom lengths of up to 20 modules per strand. Order 60 feet (4 feet x 15 rows) of stranded modules, and cut the strand after every 10 modules. Each strand can be cut to make two rows.

2. Next you’ll need to order a power supply that’s rated for the combined wattage of all sign modules. To ensure that you don’t overwork the power supply, confirm that the total wattage of your modules is at least 20 percent less than the power supply’s rated wattage.

An easy way to calculate this is to multiply the total wattage of your combined lighting by 1.2. In the 4-foot sign diagram, there are 150 modules with a current draw of 50 milliamps (mA) each. Since current draw is given in milliamps, multiply that number by voltage and move the decimal 3 places to the left to get wattage. This module consumes 50 mA and has 12 VDC operation, so it consumes 0.6 watts (50 x 12 = 600). Next, multiply 0.6 by 150 to get a combined wattage of 90 and multiply that number by 1.2 (90 x 1.2 = 108) to determine which power supply you’ll need. Since the result was 108, you will need at least a 120-watt power supply.

3. Next on the list is wire to connect all your sign module stands to the power supply. For a 4-foot sign, you’ll need 4 feet of 18-gauge two-conductor wire to serve as your main line plus enough to cover the distance between your power supply and where it will be wired into an electrical system. You’ll also need dual-channel T-tap wire splice connectors for an easy connection to your main line.

Before you begin working on your sign, turn off power to the area.

4. If there isn’t one already, drill a hole in the back of your sign as an exit point for your wire.

5. Use a tape measure or ruler to plot your row spacing. Leave space on one side of the sign for your module-to-main-line connections. Mount the sign modules using their double-sided adhesive and/or screw holes.

6. Insert the end wires of each sign module row into the T-tap splice connector, and clamp the other end of the connector onto the main line. The splice connectors eliminate the need to strip wire insulation.

7. Use double-sided foam tape to secure each T-tap splice connector to the inside of your sign.

8. Reattach your sign’s front cover.

9. Connect the main line to your power supply, wire the supply into your electrical system, and restore power to the area.

AC driven LEDs are rare but popular in certain applications. Designers focus on LEDs because of their advantages like direct, brilliant light, strong color saturation, slim measurements, dynamic lighting scenes and in total all the design possibilities that are thinkable. The only restrictions are made by the heat that needs to be dissipated by surface, natural or forced ventilation and the driver’s measurements. The driver is mostly not slim at all. That is why AC driven LEDs can be a smart consideration.

Conventional LEDs, Modules and Light Engines are driven by DC (direct current) power supplies. The LED characteristics are highly dependent on these components as they control the inrush current, convert the alternate current down to DC voltage and stabilize the current the LEDs are driven with. The efficiency of the system is dependent on the driver too as the power factor is one part in the total sum. Most conventional DC power supplies support LED systems with power factors (PFC) of 0.9 and higher.

The lifetime of LED lighting systems is defined by electronic devises. The LED can last up to 100,000h but if the driver needs a replacement after 50,000h the system is only half worth the maintenance. Without any driver at all the problem is solved completely. Power supplies need space, no matter how small, the driver is mostly bigger than the LED modules and electronic component’s wiring needs space too. Without this item there are not restrictions in design any more than heat dissipation. Designers can release their full creativity.

AC driven LEDs are of advantage concerning design and lifetime options. The more complex the circuit, the higher the possibility of system failure and electrical noise. On the other side, the efficiency of AC driven LED modules is not that high like DC driven ones. The performance achieves 110 lm/W these days which is good compared to other light sources but behind DC driven LEDs with up to 140 lm/W and more. AC driven LEDs are a thinkable substitute in applications like bulb lights, downlights, ceiling lights and industrial lighting systems.

Solar panels are an increasingly popular way to provide electricity for your home or business, but few people understand the process to install solar panels. It’s a simple process, carried out by professional installers. If you’re contemplating installing solar panels, this brief overview of the process shows you what to expect.

The process starts with a site visit, during which a contractor reviews your energy needs and the structure or area where the panels are to be installed. Keep your electric bills for the last year handy so that determining the size and arrangement of the panels is easier. The custom design is very carefully calibrated to your exact needs and will be reviewed by you and the contractor at the same time.

After all the materials are ordered and delivered, the mounting system for the panels must be installed. To take advantage of solar radiation, panels are carefully oriented and positioned so they can be turned several times of year for maximum efficiency with flush mounts.

A cheaper, but less effective solution is to mount them flat on a roof. This is more aesthetically pleasing, but don’t have the flexibility to change with the seasons.

Once the mounts are in place, the panels are set in place and wired to a system of transformers and batteries. This is the nerve center of your solar array and interfaces with the electric system in your house. If you live in an area where excess solar power is sold to utility companies, there may be additional wiring to send power back to the grid.

Every instance of solar panel installation is slightly different, and the only way to really know what to expect is to schedule a site visit with a solar panel installer that can give you an accurate estimate of the price and scope of installation. Solar power has never been a better investment, so find out how to get on board with it today.

My wife and I are the happy parents of a sixteen-month-old boy. Having a kid has turned out to be every bit as wonderful and exhausting as our family and friends told us it would be. We can see why everyone we knew with children, including our own parents, told us with that knowing smile, “Your life will never be the same.” They were right. There’s never a dull moment, is there? Every day presents new challenges and responsibilities.

For example, a couple hours ago, my son was screaming at his grandma for taking a bite of his banana. Nap time soon? Sheesh.
