In recent years, in large-scale shopping malls or activities, we always see the figure of "LED fan". Its appearance is similar to the fan, but it can display various patterns when rotating, and some can display dynamic 3D patterns, which is very cool. Every time we see it, we can always make people stop and watch it, which plays a very good role in publicity and promotion. So how do LED fans display patterns?
Strictly speaking, this so-called "fan" is just a vivid way to call it. In fact, it is a kind of "rotating LED light bar", and its professional name is holographic 3D smart glare screen. After power on, the "fan blade" starts to rotate, which can present a 3D image at the same time, cool and lifelike. At the same time, according to the size and color of the pattern, the LED fan can well hide its leaves, because there is no frame and no fixed screen, so the dynamic picture is like floating in the air, very realistic.
The 3D smart screen not only uses the hardware of rotating LED, but also uses the visual persistence of human eyes. For the hardware equipment of rotating LED, simply speaking, it is to calculate the change frequency of LED light according to the rotation speed of "fan blade". When different LED lights are lit at different times, different patterns will appear. The so-called visual persistence refers to that when the human eye is observing the scene, the light signal is transmitted to the brain nerve, which takes a short period of time. After the end of the role of light, the visual image does not disappear immediately, and the human eye can still maintain its image for about 0.1-0.4 seconds. This kind of residual vision is called "afterimage". The visual phenomenon is called "visual persistence", and the single product can be unique. Vertical display effect can also display the overall effect in combination.
3D holographic fan screen application: shopping malls, brand stores, stores, airports, etc. A good choice to reflect brand effect and brand grade
Principle of 3D holographic screen: Generally speaking, one or more strings of LED lights are arranged on the fan blades. Here, it is assumed that there are 20 LED lights, which are numbered 1-20 at a time from the axis to the edge of the fan blades. In order to explain the principle briefly, we assume that when the fan speed is 60 laps per minute (in reality, the speed is much higher), the human eye will have visual persistence. Let's assume that the LED light is 0 degrees above the fan in 0 seconds. If you want to display the effect of 6:00 on the fan, the minute hand needs to point to the top and the hour hand needs to point to the bottom. It is necessary to turn on the number 1-20 to display minute hand in 0 second, turn on the number 1-10 to display hour hand in 0.5 second, turn on the number 1-20 to display minute hand in 1 second, turn on the number 1-10 to display hour hand in 1.5 second, and so on, so that the human eye will receive a complete picture of the clock at 6:00. For complex patterns, LED fans will have more complex structure and programming equipment. Through the combination of LED light bar rotation and visual persistence, people will see a dynamic 3D picture of the rotating LED fan.
3D holographic fan screen structure: the screen body mainly has light bars and, according to different ones, some have two. Add rotary motor, built-in 3D holographic system and information receiving system.
At present, the main application of 3D smart screen is advertising. Because of its editability and realistic display effect, it is believed that in the near future, it will be applied in more fields.

Traditional lighting transformation LED, is to choose a top-down transformation or a walk on two legs, traditional lighting and LED at the same time? I believe that traditional lighting is an entrepreneur with a large child, pouring a lot of energy and effort into it, completely giving up the heart and unwillingness, can only slowly transition. Therefore, the concept of transformation often determines the pace and depth of the transformation of the enterprise.
For channel distributors of traditional lighting companies, LEDs will also face difficulties in selection.
At present, many traditional lighting dealers are not willing to accept LED lighting for several reasons: First, they have been working in the traditional lighting field for many years, and have accumulated a number of stable customers and established relatively perfect marketing channels. Secondly, the LED price system is not fully mature, the price has fallen too fast, and the LED products have become the norm. Once again, the LED home market has not been fully opened, and the engineering channel is in the right way. For the dealers, it takes too much energy to invest in the engineering channel, and the effect cannot be guaranteed.
The sales channel is the estuary of the company's products, and the importance of the company can be imagined. For companies like Shanghai Luyuan, which are at the crossroads of transformation, the demand for channel upgrades is imminent, and often determines the success or failure of enterprise transformation.
Shanghai Luyuan defined 2013 as the company's channel upgrade year and launched the “LUNO Green Energy†brand. The company will evaluate and evaluate the dealers of Shanghai Luyuan according to the LED product category and positioning, and guide those sales to be stable, loyal and reliable. Aggressive dealers are beginning to transition to LEDs and provide comprehensive support. If you have the existing marketing channels of Shanghai Luyuan, you cannot fully assume the marketing tasks after the transformation.
In addition to actively guiding the existing channel dealers to transform into LED lighting, (the company also set up a professional LED marketing team to expand new channels, support the development of a number of channels that are in line with the company's development philosophy and have certain strength to join) At the same time, we will also choose business personnel with long service time, outstanding business ability, and loyalty to the company, give entrepreneurial support, send foreign stores to open stores, operate related products of Shanghai Luyuan, such dealer team, related to enterprises and related Product familiarity, business development capabilities will be relatively strong.
The industry predicts that 2013 will be the year of LED lighting market demand, and in the field of home lighting, performance will be particularly eye-catching. Home lighting puts higher requirements on corporate marketing channels, and traditional channel upgrades will become the key to success.

Luo Quanxing: Channel upgrade determines the success or failure of transformation
[Source: Gaogong LED's "LED Lighting Channel" magazine February issue / Xiong Yuheng] After years of painstaking efforts, traditional lighting companies have a corresponding precipitation in terms of channels and brands. It can be said that the brand influence and marketing network of traditional lighting companies have obvious advantages for emerging LED lighting companies. However, traditional lighting companies cannot fully rely on existing marketing channels when transforming LEDs, and achieve the goal of transformation through simple replacement of products. After all, traditional lighting and LEDs are not completely equivalent in many aspects.
