Led driver efficiency

LED driver manufacturers believe that in the next few years, the field will witness suppliers that adopt a more integrated approach. This will make future LED drivers significantly different from what we see today. Higher levels of efficiency will become the norm, and drivers will also deliver improved performance and power monitoring. In addition, the higher integration of chip systems SoCs will continue to reduce the size of the final product while maintaining the overall design reliability.

Digital signage is another market segment that is creating huge demand for LEDs and the drivers. Save my name, email, and website in this browser for the next time I comment. Sign in.

Turtle Mobility was incorporated in the second quarter of and has been in partnership with Hero Electric since then Hero Electric has partnered with The IPO comprises fresh issue of shares worth Rs 1, crore, and an offer for sale up to 4,, equity shares by the company's This is often referred to as wall-plug efficiency.

The temperature of the LED has another often underestimated influence on the efficiency. The lower the operating temperature of the LED, the better its efficacy and thus its efficiency. Good thermal management within the light source to dissipate the waste heat from the LED to the environment would be an advantage.

An LED lamp contains various components where losses can occur. In most cases these are the following components:. The driver electronics or power supply unit converts the V mains voltage into the operating voltage required for the LED. The decisive factor here is how much light can be decoupled from the semiconductor into the environment.

The optics lenses, color filters, etc. For example, special diffusing lenses are used to achieve a certain beam angle of the lamp. The overall efficiency of an LED lamp is calculated by multiplying the individual efficiencies of all the components it contains. Do you want to calculate the efficiency of an LED light from a shop? LED illuminant delivers lumen at a power consumption of 13 watts. LED lamps and luminaires are by far the most efficient light sources of our time. However, it needs some time before all old lighting technologies are completely converted to LED.

So for our above example we would want at least The closest common power supply size will be 25 watts so it would be within your best interest to get a 25 Watt Power supply with a 24 Volt output.

The FlexBlock LED drivers are boost drivers which means they can output a higher voltage than what is supplied to them. This is extremely helpful in applications where your input voltage is limited and you need to get. As with the BuckPuck driver , the maximum number of LEDs you can power with a single driver in-series is determined by dividing the maximum output voltage of the driver by the forward voltage of your LEDs.

The FlexBlock can be connected in two different configurations and varies when it comes to input voltage. You find the maximum output voltage of the driver in this mode with this formula:. Now with AC input drivers they give off a certain amount of watts to run so you need to find the wattage of your LEDs.

You can do this by using this formula:. NOTE: It is important to consider the minimum output voltage of off-line drivers when designing your application.

For instance, the driver above has a minimum output of 15 volts. So now you should have a pretty good idea on what an LED driver is and on what you need to look for in selecting a driver with a power supply that is sufficient enough for your application.

I know there will still be questions and for that you can contact us here at or sales LEDsupply. We also have this Driver Selector tool that helps calculate what driver would be best by inputting your circuit specs. If your application requires custom size and output, please contact LEDdynamics. Thanks for following along and I hope this post helps all those wondering what LED drivers are all about. Marketing and technology enthusiast helping pave the way to a more energy efficient society.

Living in the beautiful state of Vermont and working for a company like LEDSupply that is helping provide LED products to save on energy is a great place to be in accomplishing this. Always exploring and staying active outdoors while keeping a close eye on different trends and new technologies that could change the world for the better. Im looking for 30 meters of led strip with dimmable drivers to 24 volt in warm white can you suggest.

So do you need a just one continuous piece that is 30 meters long? They require only about. Thus, I want to drive 50 parallel strings of 10 using a meanwell driver rated at about 40 watts? The little leds would consume 30 watts at 1amp at 30v. It will not be flashing at all but will gradually increase to the continuous forward current and decrease over long periods. I do want ample protection for longevity of the system so I was thinking to use resistors at each LED for a second line of protection even if I used a driver or not.

My main question of course is what is the best way to do this using this system and drivers or just resistors? Another question concerning the Buck Pucks is I have to different forward currents 20mA and 30mA, does this make a difference in which driver I should be looking at?

LED Optics Optics control the illumination pattern, either diffusing it or focusing it as your application requires.
