Mar 1, 2017: In light bulbs, light is generated by a tungsten wire which only converts a small portion of energy into visible light. This principle was followed for many years due to its simple structure and pleasant light. LED lights although have a higher luminous efficacy than light bulbs, luminaires were not considered as a replacement for light bulbs. So, in comparison to light bulbs LEDs need special attention on the power source which means, if LED’s are insufficiently supplied with energythe light keeps flickering or is perceived as choppy.
Special circuits are necessary to convert the mains voltage to a precisely matching voltage for connected luminaire. These circuits are power supplies mainly optimized for LED’s and are basically known as LED Lightning drivers. Increasing energy regulations and other factors are now resulting into energy savings associated with LED’s. LED requires driver mainly to run on a low voltage and direct current electricity; and also LED driver rectifies higher voltage, alternating current to low voltage and direct current. LED drivers also protect LED’s from voltage or current flickers. Change in voltage causes a change in current being supplied to the LED’s. Hence, too much or too little current can cause light output to vary or degrade rapidly owing to higher temperatures within the LED.
At a glance, LED drivers convert higher voltage, alternating current to low voltage, direct current and LED drivers keep the voltage & current flowing through an LED circuit at its standard level. Also, it is important to make a wise selection between constant-current drivers, constant-voltage drivers and AC LED drivers.
Commercially, the global LED driver market is anticipated to grow at a higher CAGR owing to green initiatives and power saving resolutions. Ready availability of LED bulbs and LED lighting drivers result in saving millions of dollars on energy expenditure. Therefore, with the rising popularity and overwhelming response by the audience, the LED lightning driver market is estimated to grow at a double-digit CAGR during the assessment period.
The key driving factors responsible for the growth of global LED lighting drivers market includes growth in demand of LED in lighting applications such as retail outlets, street lights, residential complexes and rapidly growing usage within the commercial applications. Additionally, residential and commercial application of LED lighting propels the market demand for LED drivers. However, the market hindering factors is lack of understanding the gap between cost and benefit by the user.
On the basis of driving method, the global LED lighting drivers market is segmented into constant volume and current volume. On the basis of end-user segment, the global LED lighting drivers market is segmented into residential and commercial. On the basis of luminaire segment, the global LED lighting drivers market is segmented into A-type Lamps and T-type Lamps.
On the basis of geographic segmentation, the global LED lighting drivers market spans North America, Europe, Japan, China, Southeast Asia and India. Southeast Asia is estimated to grow at a higher CAGR during the forecast period owing to faster growing economies like India & China. It has technologically and economically advanced economies of Japan and South Korea. India has a biggest consumer base for LED lighting products which is driving the LED market in Indian market. Strong presence of manufacturers in China is constantly enhancing consumption, conductivity and voltage aspect of LED is anticipated to upsurge the LED demand.
