Leonardo Da Vinci said “Simplicity is the Ultimate Sophistication”

Logica Lighting Controls are designed to be SIMPLE. They are simple in their operation. They are simple in their function. They are simple to install. They are simple to use.

Logica’s focus has always been to design lighting controls that are User Friendly. Not engineer driven products that have bells and whistles just because they could be done.

The fact is that most buildings were built when electricity was “penny cheap”, and there were no computer terminals on every desk. Then the recommended light levels were 100 foot candles of light. That was the norm.

Engineers designed lighting for “worst case” user requirements so that they could never be faulted for not designing in enough light. The problem was that the only control available was to switch lights on or off. If they wanted dimmer controls they had to put in incandescent lighting as well as the more efficient fluorescent lighting.

Logica Lighting Controls mission is:

“Provide lighting controls for linear fluorescent tube fixtures and all other high lumen per watt light sources to achieve different lighting intensities. Logica has patents on the technology that is based on using a microprocessor in a lighting fixture for the purpose of controlling the light levels.”

Logica has a fully developed lighting control system that is very simple and starts from the premise that people are already controlling lights in the building. They turn light switches on and off. They are used to controlling the lights in this manner. But they would like a greater degree of control. By control, they mean selecting different light levels. They shouldn’t be asked to change the way that they currently control lights to get that ability.

Logica Lighting Controls has developed a system of workplace lighting control that leaves the light switch where it is and simply adds the dimension of light level control, much like a three way light bulb in your living room. For example when a wall switch is turned on with a Logica ballast in a T8 fixture, one lamp will turn on. A vast majority of the time, one lamp in each fixture will provide enough light for normal activity.

If more light is needed users can toggle the switch off and back on within two seconds and the second light will come on in every fixture. This can be done for the third and fourth lamps in the fixture.

The ability to have multilevel lighting using only existing wiring and wall switches highlights Logica’s level of sophistication, not currently available with other lighting controls.

Our systems does not need or use a central dimmer rack, control rack, relays or switches to control our Ballasts. We do it by digital commands. Our system is a Local Area Network (LAN). By adding a microprocessor to the ballast we have an extremely reliable digital signal being sent by the user of the space (turning off and on sends a digital signal). We have a positive response from the ballast that is very predictable.

The microprocessor we use in the ballast is more powerful than the original Apple II computer. The microprocessor in the ballast gives us the ability to speak directly to the fixture from any computer control, including handheld RF wireless controls, pushbutton switches, time clock programs and manual computer controls.

Logica’s Wireless RF Gateway is the brain of our Smart System. It is the distributor of all information coming in from any source and going out to any fixture or group of fixtures.

With our Gateway on the network, inputs can come from anywhere in the world if they have the proper creds.

Our dedicated wireless controls can automate the lighting while still providing local controls for the staff working in the space. The safety and comfort of the user of the space is of utmost importance.

Our basic system is step switch dimming that allows the most efficient use of linear LED and fluorescent lamps. Linear fluorescent lamps are the most prevalent lighting product used in office buildings. LED’s will replace fluorescents in the years to come.

Our control products are made here in the USA. They are UL listed. They are CEE listed.

You can start with a single ballast and do as much as you want. Our System is scalable and allows for expansion and improvements as you go along. We can do a room, a floor, a complete building or a campus of multiple buildings.

It Simply Has To Work, Simply

In my years in the lighting business I have learned that if it doesn’t work the first time a customer uses it and consistently from then on, they will eventually find a way around the product and go back to just turning on and off the lights with a switch or a circuit breaker. This includes dimming systems and any kind of relay system. My passion has been to find a way to allow the user to have bi-level or multi-level control and still use the existing wall switch. The SwitchGenie ballast does that. It is perfect for offices with one to six or eight fixtures. The switch will control all the fixtures with our ballast that are on the same switch. I have found that lighting designers want to get fancy and put in all kinds of controls. This is great for the controls companies but the end user usually won’t learn how to use the controls and eventually gets frustrated and either just pushes the “all on” button and the “off” button so there are no controls being used. My philosophy is that if we are in the business of saving energy we need to have the default light level to be the most energy efficient light level possible. The fact that our eyes quickly adjust to the available light in the space makes the default setting provide enough usable light to do most of the tasks in the area. If more light is needed, then the switch can be toggled and another lamp comes on in each fixture so that there more light. They can do this until they have all the lamps on. Our experience is that our customers using the SwitchGenie ballast prefer the lower light levels as all most all of them work on computers and they HATE the glare of fluorescent lights. We lower that glare and make the contrast ratios more uniform in the space. Today I got a call from an existing customer that has had our 8 lamp T8 fixtures in their production facility since 2007. These lights are controlled in zones and there is push button 4 level control low voltages switch in each area so that the workers can adjust the lights to the task. This plant runs three shift and so they do adjust the lights for each area for each shift. They recently added on to their plant and we furnished them new lights for the new space. When we discussed the new lights they wanted some kind of automatic controls. I suggested occupancy sensors or a RF wireless handheld controller. We demonstrated the handheld wireless remote and they immediately chose that so the supervisor of that area can control the lights from wherever he is. The call today was to ask that we provide them with RF controls for the fixtures in the original installation. We can do that very easily by adding RF radio for each lighting group with a different address for each zone. They will have a new RF handheld transceiver for these zones. The next step is to offer them a computer program that runs on their Windows based PC where they can automatic time clock programs to control all the lights in the building. We have a plant that has 720 fixtures with our RF controls and a time clock program to control all of them. It is possible to get as sophisticated as you want with our distributed intelligent system. Once you have a microprocessor inside the fixture you can talk to it. SwitchGenie ballasts and switches are able to respond to commands from our SmartTalk computer system. It can also take commands from Energy Management and Building automation systems.

What Is ‘Light Litter’ And Why Does It Matter?

The term “Light Litter” is a great descriptive notation for the wasting of light.. Having more light than you need is wasteful. Specifically Light Litter describes the wasted light that goes into the night skies when we illuminate signs, flags and buildings from the ground and the lights shoot up into the sky. The “Dark Sky” programs are working in getting fixtures to limit their illumination to 90 degrees from ground in all directions. They discourage any light from being aimed into the sky. Our eyes are wonderful things and they adjust to available light very quickly. So we compensate for having too much light by closing our pupils. We often have to wear sunglasses outside to help our eyes. Indoors or outdoors, excess light is wasteful. The truth is that the bigger our pupils are, the better we see. Big pupils let in more light and we use more cones and rods to decipher what we are seeing.. Think of it like a printer, the more pixels you have the greater the detail in the printing. It is the same thing for the eye. To see you better you need the right amount of light for the task, not as much light as possible. My grandmother had a saying “waste not, want not”. That is something that has stayed with me all these years. The idea is, that if you don’t need something don’t take it. That goes with the concept of “turn off the lights” when you don’t need them. Distributed intelligence is putting a microprocessor in a device and having it send and receive messages from other devices with microprocessors in them. We do this with our laptops, keyboards, mouse, and printers all the time. Why not have distributed intelligence from our computer to a light fixture or group of light fixtures? The automatic control of lights can be complicated and costly. Lights being on when they are not needed can be solved by installing a relay and a photo sensor or a time clock. Some photo sensors and time clocks have the relays built in but it still means that you have to have an electrician find the circuit, locate a junction box and wire them into the circuit. Even then you don’t have an integrated program to do everything you want. The time clock has to operate with the photocell. The easier solution would be to use a wireless controller to talk to the lights or the lighting circuit directly. The use of a computer with an astrological time clock program set to the latitude of the installation provides year around control of the lights just to come on at dusk and to go off at any preset time during the night. It can get input from a photo sensor so that if a storm comes during the day the lights go on when needed. The lighting industry is well behind the HVAC industry in the use of distributed intelligence. Even the big companies are advocating relays, separate ballasts and lots of central controls to be able to communicate from a computer (Jace or PC) to a group of lights. Logica offers distributed intelligence in lighting fixtures and for lighting circuits. It isn’t new to the HVAC folks but it is new to the lighting industry. Once you have distributed intelligence you can do almost anything you want using different firmware and software. The hardware is ready to
