6 Dos and Don’ts of LED Lighting Systems It’s important to find the right lighting to illuminate your business environment. Every commercial space has its own unique lighting needs. Properly lighting an area has many benefits, most importantly worker safety and productivity. We at Stars and Stripes Lighting offer a wide range of different LED commercial lighting products that will help meet the needs of many sectors. Lighting also has a big impact on how a commercial space works, so when it comes time to decide which lighting solution is best, it’s important to make sure you’re buying the right type for your business. If you’re not sure which light fixture is best for your space, contact one of our lighting experts who will help you put together a layout to optimize your workplace’s lighting capabilities and fit your budget. We have a wide selection of LED lighting for commercial spaces, from slabs and high bays, to exit signage and moisture-proof lighting, Stars and Stripes has you covered.
LED lighting system precautions 1. Color temperature
Color temperature and lumens per watt may not be that noticeable, although you probably know you want between the brightness of an LED (at least with a flash on a circuit or light source). Color temperature applies only to white light: it is a measure of how cool (blue) or warm (red) light appears. This can be deceiving, because light color, measured in Kelvin (K), formally describes the appearance of metals (black body radiators) that burn at various high temperatures. So “cooler” or bluer colors are actually warmer. It is generally considered that warm light is 2700K to 3500K, neutral white is about 4000K, and cool white is higher than 4700K.
LED lighting system precautions 2. Light wavelength
Another common problem people have when choosing LEDs is that the shade of green or blue is not what they expected. In order to get the color you really want, you have to pay attention to the wavelength specification to determine, for example, whether to get a true green or a chartreuse. To learn more about LED wavelengths and see a visual representation of each LED wavelength in action.
Three, lumens per watt
Efficiency is measured in lumens per watt (lm/W), which is the total lumens emitted by the LED divided by the total power consumption. From experience, customers tend to target 100 lm/W for the entire system. This includes any losses due to heat, lenses, light guides and power conversion, so 140 lm/W or higher LEDs are typically required. Well-known players in LED lighting such as CREE and Samsung offer LEDs up to 200lm/W and pinpoint where that rating can be achieved. The maximum efficiency of an LED is usually achieved at a much lower current than the maximum rating, so lighting is far from exempt from the discussion of cost versus efficiency.
LED lighting system precautions 4. Indicator lights
If your application requires simple visual notification (e.g. a blinking light on a router), the whole process can be simplified with an indicator LED. Indication LEDs can be used in almost any color and can be scaled to the size of the application. Arrow ships the 0402 packaged LEDs into 10mm T-3 packages. Buying prepackaged strip lights and sets of LEDs can save time on your next design.
Five, wavelength visibility
Visibility depends on the viewing angle of the LED and how well our eyes see the chosen color, as well as the lumen output of the diode. For example, a green LED running at 2 mW looks as bright to us as a red LED running at 20 mA. The human eye has better green sensitivity than any other wavelength, and the sensitivity is skewed towards the infrared and ultraviolet on either side of this peak. Check the visible spectrum below for reference. Red is one of the more difficult colors to brighten the human eye because it is closer to the edge and can be transformed into invisible infrared light. Ironically, red is the color most commonly used as an indicator.
Precautions for led lighting system 6. Viewing angle description
The viewing angle of an LED is the distance from the center of the beam before the light loses half its intensity. Common values are 45 degrees and 120 degrees, but light pipes or other light guides that focus light into a beam may require a tighter viewing angle of 15 degrees or less. Keeping these six considerations in mind, your next LED design will be optimized for impact. Wondering if it’s better to use an OLED display?
