LED Drivers

LED driverLEDs, or light-emitting diodes, produce light when current is run through semiconductor materials. In order for this to happen, LEDs need drivers to convert higher voltage, alternating current to lower voltage, direct current. LED drivers control the voltage and current flowing through the circuit at rated levels, protecting the LEDs from voltage and current fluctuations that can damage the LEDs.

Today’s market size shows the revenue generated from LED driver sales globally in 2015 and projected for 2021. According to the U.S. Department of Energy, LED residential lighting is 75% more energy efficient than incandescent bulbs and lasts 25 times longer. Increased demand for LED lighting in retail establishments, office complexes, and residences along with demand for LED streetlights is expected to drive the growth in the LED driver market through 2021. China’s and India’s recent focus on energy efficiency is expected to lead to a growth in the LED driver market for outdoor and traffic lighting. As rapid urbanization continues in several Asia Pacific countries, infrastructure demands will also provide a growing market for LED drivers.

Back-to-School Spending

School days, school days
Dear old Golden Rule days
Reading and ‘riting and ‘rithmetic
Taught to the tune of a hick’ry stick
You were my queen in calico
I was your bashful, barefoot beau
And you wrote on my slate, “I Love You, Joe”
When we were a couple o’ kids
— Chorus of the popular American song School Days written by Will Cobb and Gus Edwards in 1907

While reading, writing, and arithmetic are still part of the curriculum, back-to-school supplies have changed quite a bit over the past century or more. Slates have been replaced by notebooks, laptops, and tablets, supplies that are on many a child’s back-to-school shopping list this year along with clothing, shoes, calculators, folders, pencils, backpacks, and lunchboxes.

Today’s market size shows the amount spent on back-to-school items for children in kindergarten through 12th grade in 2007, 2016 and 2017. Figures for 2017 are projected. While parents and guardians do most of the back-to-school spending, the National Retail Federation found that preteens and teenagers plan on spending more of their own money on school supplies in 2017 than they have in the past.
