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.

Are you sick and tired of putting food in the fridge and forgetting about it, only to find it rotten and moldy weeks later? Not only is it a waste of food, you're left with a disgusting mess to clean up. One day soon, however, your refrigerator could send you a reminder to eat your leftovers before they spoil. Read on to learn about how smart technology in your kitchen can help prevent your food from going bad.

Communicate with Your Appliances Via Text Message

As the Internet of Things becomes more prominent in our household electrical work, more and more devices are offering futuristic functions. Smart refrigerators already exist, with models that can send you a phone message when the door is left open, when the coils need cleaning and when the unit is in need of service.

A new model that Samsung has prototyped promises to take the smart technology even further. The fridge comes equipped with a touchscreen to offer you full control over its features, and a camera inside the unit that actually monitors your food and alerts you when it's been neglected for a little too long. You can use the touchscreen to check on how the food is doing, or even have the fridge send a text message that you need to eat the leftovers ASAP.

A Wealth of Inter-Connected Devices

The connectivity and versatility of our brave new world means that the next generation of refrigerators can be even more proactive about your meals. Not only can the Samsung fridge tell you when your food is bad, it has the capability to automatically order more items to replace whatever you use up or throw out. That's right, your next refrigerator could even handle food shopping for you.

The functionality of this smart refrigerator is just one example of how our electrical work is being transformed to relieve us of many of the mundane tasks of day-to-day life. In the big picture, getting alerts when your food starts to spoil might not sound like such a big deal – but imagine your fridge, stove, clothes washer, bathroom cabinet and other devices all working together make your household run more smoothly. And in the meantime, you can also dream about a world where you'll never have to subject food to the sniff test ever again!
