Diverse and impressive changes have been taking place in the lighting world this month. Read on to discover the fun and innovation!

In Lighting News…

Across the web, there was a consensus that LED holiday lights were the thing to have for the holidays. Not only are they energy-efficient, long lasting, and durable, they can also be interactive. We’ve seen families across the country creating Image via USA.Lighting.Philips.com

Other Cool Stuff…

In the last days of November, New York City residents were surprised by a light show atop the Empire State Building, synchronized to Alicia Keys’ “Empire State Of Mind.” The building’s new LED lighting system has over 16.7 million color possibilities, compared to the old system, which had only 10.

You probably know the iconic Pixar lamp – we usually see it hopping around before our movies start. Well, three students from Victoria University of Wellington have created a real-life replica of Luxo Jr., called Pinokio. With six servo motors, a webcam, some Arduino, and a bit of processing, the lamp came to life. Check out this video:

Aluminum LED profile housings allow you to create customized light fixtures with LED strip lights. Our Klus brand LED channels are available in many different styles, including recessed-, or flexible, O-shaped, and more. Available in 1- and 2-meter lengths, the channels can be easily cut for any application from under-cabinet lighting and bookshelf lighting to showcase lighting and transition strip lighting. They’re available with a variety of lens options, such as clear, frosted, and etched that complete the profiles. We’ve put together a step-by-step guide for using these channels to create your own light fixtures. Please note that your specific channel might vary from the one used in this tutorial.

Materials needed:

1. With a pair of clippers, carefully clip through the clear plastic heat shrink as shown in figures A-C. You will want to take your time and be careful not to cut the strip’s wires while removing it.

2. Lay the LED strip into the channel, and position it along the bottom so that the ends of the strip and the channel are lined up (fig. A). Now, remove the paper from the strip’s adhesive backing (fig. B), and adhere the strip to the LED channel—starting at the lined end and working your way to the other end of the strip. Be sure to leave roughly 1/4-inch free at the end of the channel so that you can install the end cap as shown in figure C.

3. If one of your end caps doesn’t come with a pre-drilled hole, you will need to drill your own to allow the wires of the LED strip light to come through. In this case, we used a Dremel tool, but other options are viable as well. Regardless of the tool you choose, it is helpful to mark the end cap where you would like the wires to come through. Start the hole small, and increase the size as necessary.

4. Place the end cap on the wired side of the strip by threading the wires through the end cap as shown in figure A. Insert the end cap into the end of the light bar, and push firmly until it is fully in place (fig. B).

5. On the open end of the bar, slightly peel up the end of the LED strip (fig. A); this is necessary to install the end cap. Now measure your channel lens, and trim off the excess with clippers (fig. B). Be careful when trimming to avoid cracking the plastic. Excess material can be lightly sanded off. Once the lens has been cut to the proper length, slide it into the channel, and install the end cap as shown in figures C and D.

6. That’s it! Your customized LED light fixture is complete and ready for installation, which we will cover in the next step.

7. Mounting this LED profile is as easy as applying double-sided tape to the back of it and sticking it to your intended surface. Be sure to cut the tape to fit the back of the LED profile and to leave the tape backing on the side not attached to the channel until you are ready to mount it.

For most LED profiles, mounting clips are available for a more permanent installation.

constant-current LED driver or constant-current driver is used to regulate the amount of current that is supplied to an LED or LED array to maximize LED lifetime. If current is not regulated, LED brightness can fluctuate and life span can be shortened. The constant-current driver is used for LEDs or light fixtures that require a stable output current and operate within a range of voltages. Most finished LED products already have a constant-current driver or resistors to regulate current. If you’re building an LED fixture or replacing a constant-current driver, it’s important to verify that the output current and voltage of the driver is compatible with the LEDs’ current and voltage. If your LED product already has a constant-current driver or uses resistors in the LED array, you might need a constant-voltage power supply.

If your LEDs are dimmable and you want to change their brightness, choose a Magnitude Dimmable Power Supplies. These dimmable power supplies work by varying the power on the AC input side of the power supply by means of a TRIAC dimmer. This change in power on the AC input side will vary the voltage on the DC output side and control the intensity of the LEDs. TRIAC dimmers are common hardware store and household dimmers, which include brand names such as Lutron and Leviton.

Pulse-Width Modulation Dimming: Pulse-width modulation (PWM) dimming can be used to control dimmable power supplies such as Mean Well LPF Series. This type of dimming control adjusts the output current based on the duty cycle. As the duty cycle increases, current will increase and the LEDs will be brighter. Conversely, if the duty cycle decreases, the current will decrease and the LEDs will be dimmer. Pulse-width modulation for these drivers is based on a 10-volt signal level with a frequency between 100Hz-3KHz. The MLD-5A are compatible for this application.

Resistive Dimming: Resistive dimming can be used to control dimmable power supplies such as 12-Volt Mean Well HLG-40-240 Series or 12-Volt Mean Well HLG-600 Series or here.

The efficiency of a power supply or driver indicates the percentage of power that goes toward making your LED product function. An efficiency of 80 percent or higher is recommended for operating LEDs. 

When choosing a driver or power supply, the size of an LED product’s housing or area of installation is important. If you wish to put a constant-current LED driver inside of a product, the driver must be small enough to fit in the product’s housing. Similarly, if the driver or power supply is used outside of the product’s housing, it should fit the area of installation. Drivers and power supplies are available in a variety of sizes to suit your needs.

A Class 2 driver or power supply is in accordance with limited power levels defined by the National Electric Code (NEC) and fulfills the requirements of Standard UL 1310. Output is limited to 60 volts DC and 100 watts. Because power sources with this rating have limited output, it might not be possible to power as many LEDs or lights as those that don’t have a Class 2 rating. However, these power supplies and drivers provide protection from fire and electric shock.

A Class II rating refers to a double insulation layer between AC input and DC output wires. These drivers and power supplies do not require a ground connection.
