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.

Many homeowners start to get nervous when cooler weather starts to set in. Thinking about the rising heat bills is stressful, especially if you have holiday shopping to do. But don’t panic just yet: there are plenty of simple actions that can result in major savings! If you follow these 6 tips below, you’re likely to see a positive change in your energy bill.

With the latest trend of installing recessed lighting in the interior of a home, many homeowners are wondering if the lights are a good option for outside as well. Recessed lighting offers many benefits and it just makes sense to take advantage of the latest and greatest lighting systems on the inside and outside of your home. The fixtures can be installed by an experienced electrician in Pasadena in a single day typically. That means you will be enjoying your new outdoor lighting that evening! You can call The Electric Connection to find out how soon you can schedule your lighting installation.

Check out some of the benefits to having recessed lighting installed on the outside of your home by a Pasadena electrician.

They don’t take up any room Lights are flush and do not hang down, interfering with plants or at risk of being broken

Hiring an Electrician

Although the lights are fairly simple to install, it is best to have the installation completed by a professional electrician. Pasadena homeowners won’t have to worry about ensuring the lights are properly insulated from the elements. There is also an issue of the light touching insulation. There will need to be a hole cut into the home to install the light and it is important it does not create a fire hazard by touching wires or insulation.

There are several styles of lights to choose from. You will want to choose one that is right for your needs. Recessed lights with reflective trims tend to be brighter and are a great option for areas that are particularly dark. Check out your home improvement store to get an idea of what you want and then give The Electric Connection a call and schedule your installation.
