How many kinds of the drive power of the LED tube

More and more LED Tube is currently applied as the office and daily lighting, the drive power is one of the very important component parts, then what is the difference with the drive power of the LED tube light?


The drive power of the LED tube can be divided into two categories:

(1) constant-current type:

a, the current the constant current drive circuit output is constant, the output DC voltage vary within a certain range with the different sizes of load resistance, the load resistance is small, the output voltage is low, the resistance of the load is greater, the higher the output voltage;

b, constant current circuit is not afraid of the load short, but prohibited that the load is

completely open.

c, the drive circuit of the constant-current LED is an ideal, but the prices is relatively higher.

d, pay attention to the maximum withstand current and voltage values used ​​, which limits the use of LED quantity;

(2) Regulators type:

a, when the parameters of the regulator circuit is determined, the output voltage is fixed, but the output current varies with the load change;

b, the voltage regulator circuit is not afraid of the open load, but non-load mustn’t completely be shorted.

c, regulator driver circuits drive LED, each string needs to be coupled with an appropriate resistor so that each string of LED display brightness average;

d, brightness will be subject to be variant from rectified voltage.

Nowadays,the LED flood lamps and LED tube light are the most widely used as the representatives of the decorative lighting and the home lighting in daily life,the LED tube light enjoys a great popularity in our corridor, restaurants, shopping, leisure and entertainment, galleries, exhibition halls and other indoor environments everywhere, the LED flood lamps is mainly used in city squares, parks, stadiums, the facades of large commercial buildings and hotel, stage, waiting rooms, airports etc. where the higher brightness is needed to illuminate,meanwhile,there a large number of factory engaging in developing and producing the LED light,Lead Lighting is just one of them,which adopts high brightness SMD as the light source of the LED tube and highly integrated and high brightness COB as the light source of the LED flood lamps so that fully guaranteed stable and soft light of the LED tube light and octahedron breadth and brightness irradiation range of the LED floodlight, while low voltage constant current driver ensure the AC can be converted into the DC to improve energy efficiency of the LED tube light and LED flood lamps and reduce the waste heat energy and stroboscopic effect exciting the human eye, the most important is that the LED lighting without adding mercury and other heavy metals harmful to our body and pollution the environment, that’s why the LED light is Known as energy-saving and environmental protection. Login to learn more features and uses of the LED tube light and surf  to know more awesome LED floodlights and other LED lighting.

    Comments are those wonderful sign posts along the blogway that tell me people are reading what I write. Good bad or indifferent they are a great indicator for the blogger to use as a means to direct and facilitate the conversation. Which in my opinion is what it’s all about. Thanks for your post…
