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 .
Nowadays，the LED flood light such as the portable LED flood light 30W 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 light 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 light so that fully guaranteed stable and soft light of the LED tube light and octahedron breadth and brightness irradiation range of the LED flood light, 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 light 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.
