Eight dimensional analysis of small spacing LED engineering display advantage Comparison of mainstream display technology In the field of indoor engineering display, small spacing LED display as a latecomer, you need to deal with the competition from the DLP splicing, [...]

Why is the highest price of LED lamps? Recently, the public Liu to the supermarket to buy light bulbs, bulb shelves can let him pick hualiaoyan a superb collection of beautiful things. "In addition to the traditional incandescent and energy-saving lamps, and a LED lamp, I don't know how to lighting the lamp?" incandescent lamp, energy saving lamp, LED lamp which cost-effective? Found through experiments, home lighting or cost-effective LED lamps. LED lamp is 16 times more expensive than incandescent lamp At present, incandescent lamps are facing the situation is gradually eliminated, energy-saving lamps become mainstream in the market. The [...]

Design of side guide light LED backlight I. Introduction As human society entered the era of knowledge economy, information and knowledge to achieve real-time, with terminal equipment to achieve the exchange of information display technology is developing rapidly, as the LCD display technology is one of the developed very fast, because LCD has its own shortcomings in no light, so most applications require supporting backlight. The backlight used is incandescent bulb, cold cathode fluorescent tube, EL and LED lamps, etc.. Each backlight technology has its own characteristics in a specific application environment. One of the advantages of LED technology has [...]

Chip is the core component of LED. At present, many domestic and foreign manufacturers of LED chip, and chip classification has no unified standard, according to the power classification, there are a large power and small power; if classified by color, mainly red, green, blue three; if the classification based on the shape, generally divided into square plate, two kinds of wafer; if according to the voltage classification, is divided into low voltage and high voltage DC DC chip chip. Comparison of domestic and foreign chip technology, foreign chip technology, the domestic chip production is not heavy technology. Substrate material [...]

LED era, we in all aspects of life are visible in its presence, whether it is a car field, intelligence or industrial fields, because of its high efficiency, energy saving, long life, environmental protection and other features, the optional scheme has now lighting technology, and has been applied in lighting. One of the key factors that drive people to pay attention to LED lighting technology is that it greatly reduces the energy consumption and can achieve long-term and reliable work. Today, we will give you a practical extension of the LED circuit from the introduction of LED lighting drive circuit. [...]

First of all, let's talk about what is the LED driver power supply? It can convert the power supply to a specific voltage current to drive the LED voltage converter, normally: LED drive power supply input, including high voltage ac power frequency (mains), low-voltage dc, high-voltage direct current, low voltage high frequency ac (such as the output of electronic transformer). And the output of the LED driver power supply are mostly can change with LED positive pressure drop values and change the voltage of the constant current source. LED core components including power switch controller, the inductor, switch components (MOSfet), [...]

LED is a highly efficient light-emitting diode device, it must work in a constant current environment in order to continue to emit a steady bright light to illuminate the world. The driving power of the pros and cons will directly affect its luminous brightness and light quality. How to choose a good LED filament driving power supply is the key to the manufacture of LED filament lamp with good performance price ratio. At present, there are three kinds of power supply for LED filament lamp: One is about to be out of the resistance capacitance step-down power supply; Two is [...]

The problem about power LED flashlight: buy LED flashlight, some consumers blindly pursue high power flashlight, the higher power that represents the brightness is high, this is actually a misunderstanding to buy a flashlight. LED is a flashlight in the market is very popular, one of the reasons is because of its low power consumption, using the same battery capacity, long lighting time than ordinary flashlight, flashlight and between the power and the brightness is not completely proportional relationship, this also relates to a solar energy conversion, the greater the power only that, energy consumption is high, in fact, as [...]

Running water has great influence on the jade jade? Jade jade is not very expensive, but if you do not pay attention to the preservation of it may also appear the phenomenon of running water. Xiuyu running water will make the color and the degree of permeability becomes worse. There are many businesses in order to reduce the loss of water will run on the jade have a period of time in the water, the absorption of sufficient moisture to sell out, but when consumers buy a home, jade will return to the running water face. The effect of water [...]

According to South Korean media reported rumors, SHARP has informed the factory of Korea SamSung (Samsung), since 2017 will no longer provide LED screen panel to Samsung, Samsung makes the face panel gap of approximately 4 million pieces per year, emergency orders to another Korean panel maker LGD, according to the "Daily News" the science and technology news that SHARP Hon Hai shares investment, since the beginning of 2017 will sprint TV market. In the current panel production capacity, can not meet the needs of all, so SHARP will raise panel price, Samsung is no longer inclined to buy the [...]

At the beginning of the new year is the time of new Vientiane, Moupian layout. The first week of 2017, many LED companies will have moves: the chip giant raised the prices of some products, an optoelectronic Rawlinson a total investment of 5 billion 500 million LED lighting projects, Riyadh fund-raising 1 billion 200 million overweight VR/AR, Wright cross when the teacher ""...... "Several days of silence," the LED circle so lively again. More exciting please continue to look down! [dynamic] big coffee The industry of LED double Ruo price? Three new year price first shot fired" 2017 started the [...]

In 2017, will be an important moment in the television industry, the global TV manufacturers are in the technical route and business development of their respective crossroads." In the United States on January 4th local time on the eve of the opening of CES2017, Hisense group president Liu Hongxin officially announced the technology and product line. That night, in addition to released the world's first brightness, color gamut than LED dual color 4K laser TV, Hisense spotted QLED. Liu Hongxin said that as a new semiconductor nanomaterials, quantum dots with many unique nano properties, is an important material for the [...]
