Frequently Asked Questions
Configuration & Installation Questions:
What is an L.E.D.?
A Light Emitting Diode (LED) is a solid-state semiconductor device that emits visible light when an electric current flows through it. The process of electroluminescence within an LED is rapid in comparison to conventional lighting source, thus leading to better efficiency and a longer lifetime. The applications for LED lighting are widespread due to the small size of an LED chip and the broad selection of colors that it can emit. LED chip manufacturers continue to improve the performance and efficiency of high power LEDs, thus increasing the prominence and usage of LED’s as a primary light source.
What is the lifetime of an LED?
The lifetime of an LED varies according to the chip manufacturer, operating conditions, and environment. American Illumination typically uses CREE or Nichia LED chips, which have a projected lifetime of 50,000 hours at no less than 70% lumen maintenance under proper operating conditions. However, it is important to note that an LED system is only as strong as its weakest link, and American Illumination recommends installing a surge protection device on the primary of any LED circuit.
What is the best thermal management method for LED’s?
Good LED fixture design requires proper thermal management to prevent heat-related failures. Passive thermal management includes “conduction” and “convection” in order to prevent heat from damaging the LED junction, thereby preventing premature failure. Heat sinks are housings or structures, typically made of aluminum, which are installed in contact with the LED board and conduct heat away from the LED junction and dispel it to the open air. Typically, heat sinks have a finned structure to increase surface area and maximize thermal dissipation from the source. Clients should consult American Illumination when selecting the proper thermal management method for LED products.
For enclosed or sealed fixtures, American Illumination recommends full contact between the heat sink and inner fixture surface to ensure maximum heat transfer to the ambient air. Furthermore, the use of graphite tape or active thermal dissipation in the form of a fan can be used to propagate additional heat management.
American Illumination recommends thermal testing for all new LED applications. Clients can test the temperature on the LED thermal pad, heat sink and fixture housing by using a temperature prod or laser thermometer. It is recommended to allow the light to operate for at least one hour prior to testing each crucial point to allow the light to “heat up” to its maximum average temperature. For extra high output LED sources, clients can utilize thermal imaging services to project heat flow in a given system or fixture.
What correlated color temperatures are available?
American Illumination offers all in-house designs in 2750K, 3000K, 4000K and 6000K as standard white CCT’s. Additionally, non-standard CCT’s such as 3500K, 4500K, 5000K, and IR can be sourced for custom and special projects. American Illumination also offers most products in RGB, RGBW, and RGBA.
I need a modified or custom design. Can American Illumination accommodate my order?
American Illumination strives to meet clients’ needs based on their project and/or proposed design, whether it’s a one-off or continued use product. Custom features can include wire/cable types, LED colors/brands, housing finish, and housing material, to completely unique and one of a kind designs. Additionally, American Illumination offers full-scale private label solutions, from an LED board level to full fixture package, as well as overseas sourcing services. Contact American Illumination at email@example.com to get started.
Are American Illumination products built for parallel or daisy chain wiring?
American Illumination, Inc. in-house brand products are built with an internal constant current driver, and are therefore meant to be wired in parallel.
Are your LED light engines dimmable?
Yes, they are generally dimmable but some market transformers incorporate more sophisticated and complex features, which may represent a conflict with the LED driver circuit. Since American Illumination assumes no control over third party dimmer or transformer circuit components, dimmability may not occur with 100% of transformers/dimmers.
What is the maximum distance allowable between a 12V American Illumination product and my power supply?
The maximum distance allowed is dependent on the voltage drop of the wire between the power supply and the LED light. Most American Illumination 12V products operate between a voltage range such that there is an allowable amount of voltage drop without affecting the performance of the light. For example, if your power supply is set at exactly 12V and you are using the 9-15V Light Plugz, then the maximum allowable voltage drop is 3V or a 30 meter line cord (approximately 100 feet). The absolute maximum distance is 200 feet if your power supply is set at a higher voltage of 15V. End users are recommended to use 18 ga. wire minimum for lighting installations.
What is the maximum number of 12V CV LED lights allowable per power supply?
If you already have a given power supply and want to determine how many LED products you can string in parallel:
- Deduct 30% from the total power supply wattage as a safety margin.
- Divide the gross (total) wattage by the maximum power consumption (refer to Product Specifications) of each light.
- Round your answer down (or drop the remainder).
To determine the power supply you need based on a specific number of identical lights:
- Calculate the sum of the maximum power consumption for one light and the line loss.
- Multiply the number of desired Light Plugz in the string by the sum you calculated in Step 1. This is your maximum total power consumption.
- A typical power supply should have a safety margin of 30%. To select a sufficient power supply to constantly power your string of LED lights, divide your maximum total power consumption by 0.7 and round up to the nearest wattage.
How do I determine the polarity of each lead?
Unless marked otherwise, American Illumination in-house brand product leads are not marked for low voltage LED engines because they are both AC/DC safe.
Should I use a constant current LED driver for your low voltage LED light engines?
No. American Illumination in-house brand low voltage products already have an internal constant current driver. To see a list of approved types of power supplies and transformers for low voltage LED products, please click here.
