What does LED mean — light emitting diode

LED is a loanword, is the abbreviation of English Light Emitting Diode three initials, translated into Chinese, is light-emitting Diode, is a light-emitting Diode, semiconductor device. LED light emitting diode (LED) is a common light-emitting device, which emits light through the compound release of electrons and holes. Its main application fields are: lighting and display fields. LED light emitting diode appeared earlier in 1962, early used in display devices, in recent 10 years gradually become the main light source devices in the field of lighting.

At present, almost all non-natural luminescence has LED behind it. To sum up, there are two main categories of applications: lighting and display. Either LED already, or LED can be replaced. For example, our common lighting field LED lamp, flexible led strip (including T8led lamp, T5led lamp, T8led lamp bracket, T5led lamp bracket, T8 to T5led daylight lamp), LED street lamp, LED mining lamp, LED projector lamp, LED floodlamp, LED tunnel lamp, LED panel lamp, LED down lights, LED bulbs, etc., although there are still some occasions still use incandescent lamps, energy-saving lamps, or old-fashioned daylight tubes, but can be replaced by the corresponding LED lights; Display field LED display, LED display, LED TV, traffic lights, traffic lights, instrument power indicators and so on.

2, LED lights are light-emitting diodes, is the use of solid semiconductor chips as light-emitting materials, compared with traditional lamps and lanterns, rigid strip lights, environmental protection, color rendering and response speed is good.

(a) high light efficiency is the prominent feature of LED lamp

At present, the light efficiency of LED lamp bead mass production is as high as 185LM /W. After removing the loss of LED constant current drive power and lamps, the light efficiency of finished LED lamp can still reach about 155LM. The mainstream LED light efficiency on the market is basically above 100lm/W. Compared with the traditional incandescent lamp 15lm/W, ordinary fluorescent lamp 33lm/W and 40lm/W, the light efficiency is improved 5-10 times.

(2) Energy saving is another significant feature of LED lights

LED light has high efficiency. Under the requirement of illumination, the power of LED lamp can be greatly reduced. For example, the power of LED lamp is one tenth of that of traditional incandescent lamp and one fourth of that of energy-saving lamp.

Energy saving is also the killer card for LED lamps to replace ordinary incandescent lamps and energy-saving lamps. For example, an 8-10W LED bulb can be used to replace 100W incandescent lamps, so that the brightness will be brighter. The 24-hour working system only needs 3-5 days to save the electricity bill to buy an LED bulb lamp. Led lamp tube to replace ordinary fluorescent lamp, 24 hours working system, 1.5 months saved electricity can recover the cost of replacement, the entire life cycle saving of electricity is up to an amazing 1650 degrees! Few can refuse!

(three) LED lights are almost unlimited switching times

Leds can be switched on and off almost indefinitely, hundreds of times more than incandescents and CFLS, regular tubes and tri-color tubes. Every time the incandescent lamp switch, the filament has cold and hot shock, to a certain number of filament fracture, the incandescent lamp is damaged; Ordinary daylight lamp using inductance ballast start is the filament cathode preheating, only about 20,000 times of switch times, three color T5 fluorescent lamp most use no preheating power of electronic ballast, life is only about 6500 times, energy-saving lamp is only a few hundred times. When LED lamp is doing switch test, do not need to do any special design, can easily achieve millions of switch times. And namely open namely bright, turn on the lamp namely is brighter when, after reaching heat balance normally 15-30 minutes namely enter stable luminous state, reach stable time also is far lower than common fluorescent lamp.

(4) Extremely long life

Compared with the life of ordinary incandescent lamp of 1000 hours, the life of ordinary lamp of 3000 hours, the life of LED lamp is significantly increased, the life of normal quality LED lamp is as high as 40,000-50000 hours, even if the 24-hour working system, can easily reach more than 5 years, if the household, with an average of 4 hours a day calculation, In theory it can reach a jaw-dropping 34 years, but in practice it is possible to use it for 20 years or so. LED lamp in a large number of commercial and engineering applications, has been working for five years LED lamp has too many application cases, and in the occasion of high life requirements, can reduce the LED lamp bead current, strengthen the heat dissipation, to achieve a longer service life.

mainly provide 145LM /W high brightness long life LED lamps, including led lamp, LED fluorescent lamp (including T8led lamp, T5led lamp, T8led lamp bracket, T5led lamp bracket, T8 to T5led daylight lamp), LED street lamp, LED mining lamp, LED projection lamp, LED floodlights, LED tunnel lights, LED panel lights, LED down lights, LED bulbs, etc. All use high temperature resistant lamp beads, high heat dissipation redundancy, drive all use long life high reliability LED drive, only for customers five years “zero” maintenance.

LED fluorescent lamp (LED lamp) main advantages

More than half of the same brightness electricity costs saved;

It saves 78 KWH of electricity per year and 450 KWH of electricity in the whole life cycle.

T8led lamp 9W can replace other first-line brand market circulation 16-24WT8LED glass lamp, save half of electricity, save more than 78 KWH of electricity per year, 50000 hours life cycle can save more than 450 KWH of electricity, save half of electricity at the same time brightness increase about 15%;

Ultra high brightness, the same power brightness is more than double, brighter than the main circulation T8LED lamp on the market;

The brightness of 18WT8led lamp tube is 2.5-3 times that of other first-line brands; One lamp = two lamps of other first-line brands;

High reliability, long life, 3-5 years almost no bad one, 5 years no flash, five years warranty, one top three;

T8led lamp with high temperature resistance lamp bead (most of the rest of the market LED fluorescent lamp usually use ordinary high temperature resistance LED lamp bead), drive and heat dissipation triple redundancy, 2500V lightning protection surge prevention high prevention process, so that accidental damage no longer occur;

High thermal conductivity aluminum substrate and special process to ensure that the brightness of 3-5 years almost no obvious decline; Using 100,000 hours long life high voltage high temperature resistance electrolytic capacitor, driving life up to 10 years.
