What’s the main structure and components of the LED lights

LED is a semiconductor light-emitting diode, LED energy-saving lamps is the light lamps whose light source is high brightness and white light-emitting diode, which is of high luminous efficiency, low power consumption, long life, easy to control and maintain, safety and environmental protection; and is a new generation of solid cold light source, soft light color, bright, colorful, low loss, low energy consumption, environmental protection, suitable for home, shopping malls, banks, hospitals, hotels, restaurants him various public places for a long time lighting. No flash DC, play a very good protective effect on the eyes, the best choice for the table light and flashlight.

The main structure and components:

People understood the basic knowledge that the semiconductor material can produce light 50 years ago, the first commercial diode was produced in 1960. LED is the English acronym that is the light emitting diode (LED), and its basic structure is an electroluminescent semiconductor materials, which is placed on a wire rack, then sealed with epoxy resin around to protect the internal core wire, so the LED’s known as seismic performance.

The difference between the LED lights and energy-saving lamps

The main structure of the LED is different because of the purposes, the main change in structure, the following will focus on the main structure of the household LED bulb:

Grading system – compose of  the LED light board (light source) / thermal panels and light mask / light shells and other structures;

Heat dissipation system  – a thermally conductive plate (column), internal and external radiators and other structures;

Drive power – the high-frequency current source, linear constant current source, AC utility power;

Mechanical / protective structures – the radiator / shell, lamp / insulating sleeve, both mask / light shells and other structures.

Further, according to the overall structure of the two characteristics, and can be divided into:

Incandescent bulbs – single Integral;

LED bulbs – Integral / Split / bulls and other forms of combined

there are other composition factors of the LED energy-saving bulbs:

1. Voltage : LED using power supply that is of low voltage , the voltage of the power supply is between 6-24V , varies depending on the product , so it is power supply that is more secure than those using a high voltage , especially for public places.

2.Performance: the consumption of energy efficiency is 20% reduction compared with incandescent light .

3. Applicability: small , each small piece of unit LED is 3-5mm square , it can be prepared into various shapes of devices, and is suitable for the environment variable .

4. Stability: 50,000 hours , the light fades is 50% of the initial.

5.Response time: the incandescent is of millisecond response time , LED lights is nanosecond response time.

6.environmental pollution: less harmful metal mercury .

7.Color: the color is changed as the current is changed , the light-emitting diodes can easily adjust the material’s band structure and band gap by chemical modification methods to achieve multi-color light that are orange red yellow green and blue . for instant the small current generate the red LED, as the current increases, it can be turn into orange , yellow, and finally green.

8.Price : LED ‘s price is expensive, compared to incandescent lamps , the price of a few incandescent lamp is considerably with the price of  LED , and often each signal compose of 300 ~ 500 diodes .

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?

DSC_0321

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.
