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.

From movies candle-lit dinners, lighting is one of the most important factors in everything we do.  Science and technology teams around the world have put an amazing amount of effort into developing the sturdiest, longest-lasting lights for any application you can think of.  Color, saturation, brightness, and even beam shape are all important when it comes to picking the right light for the situation.  The best part?  Mood lighting is a careful art that’s pretty easy to pull off once you know which settings work best.  Romantic lighting is especially simple and can set the stage so long as you have the right room and the right lights.

It could be our culture that has led us to see certain settings as romantic.  But there are also a few scientific aspects of lighting that genuinely make a setting more romantic.  While it may be that decades of amber-colored lights or the flicker of candlelight have fashioned our notions of what makes for romantic lighting, there’s also the effect of the light itself to consider.

Light with a low color temperature (below 3000K, or ‘yellow’ light) produces a very interesting effect on surfaces.  These lights, which are standard for most incandescent lamps, soften features and improve appearances.  If you want to look good, use an incandescent lamp.  While not ideal for getting ready in the morning, a standard light gives that warm and cozy feeling we all enjoy from standard incandescent bulbs.

The next step is to keep the lights dimmer than normal.  Dimmer lighting creates a closer, more intimate feeling to any room.  But there is a trick to this.  Don’t simply remove a few light bulbs from the dining room, you need to use an actual dimmer.  Uneven lighting is jarring and distracting.  Removing lamps or relying on recessed lights that have been dimmed can ruin the effect.  Recessed lighting that’s been dimmed can create cave-lighting (when there are unintended dark corners along the upper part of the wall).  Uneven lighting isn’t cozy, it’s distracting.  Use a dimmer switch.  Just be sure to match your dimmer to the type of lights you’re using.  If you plan to use LED lamps, make sure the dimmer is compatible with your brand of LEDs.

When we say to keep lighting even, we don’t mean equal throughout the room.  Even lighting in this case is designed to highlight focus areas.  Think about how restaurants stagger their lighting, with islands of light at each table and muted lights everywhere else.  If you want the greatest effect, use a fixture that focuses a soft light where you’ll be spending your time while ambient lighting casts a light glow everywhere else.

A romantic setting demands more than just the right lighting.  Pair the lighting with a favorite meal or entertainment.  Some background music will set things off nicely, but only if you select something that matches the mood.  You may enjoy electronic dubstep, but when the lights are lower something quiet and soothing is the way to go.

Explosion proof fixtures are a necessity for environments which output potentially explosive or flammable fumes, produce dust of dirt in the air, or similar situations in which a gas could enter the fixture and cause damage to the light or well-being of the facility.

If you are currently running or working with a facility which requires these explosion proof light fixtures, the list of 3 must-haves below will clear the air and hopefully set you on the right track to ensuring you have the proper setup and design.

 

First on the list, we are going to talk about the actual technology within the fixture and why it is so important.

 

 

While a big part of vapor proof lights is the actual fixture and its design, we think the luminaire within the fixture is equally as important.

We simply can’t recommend any other technology other than LED because we truly believe in it. To give you a little bit of insight on industrial LEDs, here are some of the reasons why companies of all sorts are converting to LED:

As you can see, just from these three main benefits that all sorts of facilities are realizing can really be game changing in terms of savings.

For these reasons (and more), we thought it was a must to have it first on the list.

 

Interested in learning more? Find Class 1 Div 2. For this reason, we suggest you always inquire with a reputable and knowledgeable company that offers and deals with explosion proof lighting when inquiring about your lighting project.

If you can’t find a reputable company to ask your questions, just LED explosion proofs offer the long-term solution is clear.

Especially when you consider in rebates, your initial upfront investment can be reduced greatly. While these rebates do vary from place to place, they are most often available when you buy DLC qualified fixtures. Not only are DLC qualified fixtures going to make you more eligible for rebates through your utility company, but they also provide other benefits. The biggest benefit of buying DLC qualified lights is they have ben tried and tested and, in most cases, do what they claim. In a busy world of lighting, not all products do exactly what they say. This is most common when a light is not qualified by something like the DLC.

Our main advice is this; to get the best value buy only DLC qualified fixtures. If you don’t, you may actually end up spending more upfront (by not getting any rebates) as well as more energy usage overtime, due to a less efficient build.

 

Another major cost saver can come through retrofitting. The only time you can retrofit is if your fixture is still functional and can fit a LED retrofit in it. If you do not match these requirements, then a full replacement will (typically) be required.

If you can, we suggest you retrofit. It saves money in two ways: retrofit kits are cheaper than full fixture replacements and the cost to retrofit is typically less time consuming and thus, less expensive.

 

 

In Summary

We know that a sensitive environment can be stressful to deal with, especially when it comes to the lighting system and the safety of the facility.

The above 3 must-haves are just the beginning, and each situation can vary greatly. As always, we suggest you consult with some lighting professionals to truly discover what you may require for your facility and operations.
