Is it possible to sit in the blue sky and white clouds and sunlight even if you hide in the basement? In fact, Italy and Japan have developed such lamps, indoors also seem to be in the outside sky, enjoy a very natural, comfortable light environment, to give lighting a new connotation. So, what is the principle of this lamp? How effective is the price and use? Starting from the sky lanterns developed in China, the Aladdin News Center analyzes the principles and effects of sky lanterns in depth, and presents the Chinese manufacturing and Chinese wisdom in the new era.
Never before has there been such a strong awareness of the positive effects of the natural environment on human physical and mental health as it is today. For lighting, we are no longer just purely pursuing light effects, but more adding the positive effect of light on people. How to pursue the harmonious coexistence and integration and symbiosis between man and nature in a healthy and natural light environment has also become the consensus for which the lighting industry strives.
The era of skylights is coming: let the sun live in the room
In natural healing, light and blue sky are important expressions. However, there are still many people whose living and working environments do not shine in the sun or have poor lighting conditions, such as hospital wards, subway stations, office spaces, etc. In the long run, it is not only bad for the body, but also will make people feel impatient and stressed, affecting mental health.
So is it possible for people to enjoy the blue sky, white clouds and sunshine in the dim basement?
Sky lanterns make this imagination a reality. In real nature, due to the presence of countless tiny particles in the atmosphere that are invisible to the naked eye, when sunlight passes through the atmosphere, short-wavelength blue light hits these small particles and scatters, making the sky appear blue. This phenomenon is called the Rayleigh effect, and the "blue sky lamp" designed according to this principle will present a very natural and comfortable lighting effect, as if it is really under the sky outside, and it is installed indoors, which is equivalent to installing a skylight.

It is understood that the world's first LED lamp with the best simulation of natural light based on this principle was developed by the Italian company Coelux. At the 2018 Frankfurt Lighting Show in Germany, a daylight simulation device developed by Coelux in Italy - Coelux system attracted wide attention from exhibitors; in early 2020, Japan's Mitsubishi Electric launched a lighting system called "Misola", whose LED display can simulate the picture of the blue sky, and has gathered a high degree of topic in the lighting market before it is sold. In addition, the well-known brand Dyson has also launched a lamp called Lightcycle, which can simulate natural light in a day according to the human biological clock.
The development potential of sky lanterns is evident.
The next blue ocean market for the industry
The emergence of sky lanterns has brought human beings into a healthy era that is truly in line with nature. In closed and windowless indoor spaces such as residences, office spaces, shopping malls, hotels, hospitals, etc., skylights are playing an active role. Nowadays, in this market, many domestic local brands have begun to rub their fists and launch their own fist products.
Domestic lighting manufacturers such as Changzhou Fengsheng Technology, OPPLE Lighting, Yeelight, Sanxiong Aurora, Shenzhen One Window Technology, etc. have launched blue sky lamps that simulate daylight illumination in a timely manner, in order to fully simulate the feeling of the sky through technological breakthroughs, so that people who have been living indoors or dim environments, such as ICU wards, basements, etc. can enjoy the sunlight.

In an interview with the Aladdin News Center reporter, Ge Weixin, deputy general manager of Changzhou Fengsheng Technology Co., Ltd., said: "Skylight, as a solution that can solve the current factors of the lamp to the psychological environment of people, is the next direction for the development of the lighting industry. Changzhou Fengsheng Technology attaches great importance to this technology, and we believe that sky lanterns will bring great application value to people who live and work in indoor environments or dim environments for a long time in the future. ”
It can be seen that sky lights are gradually favored by the market for their advantages of simulating outdoor blue sky light environment and can be widely used in indoor lighting such as homes, office buildings, shopping malls, stadiums, stations, airports, etc.
The high price has become a constraint on the popularity of sky lights
Although the future application value of sky lanterns is considerable, due to the current expensive price of sky lanterns and the lack of systematic popularization, the promotion of the market has brought great obstacles, and the application market has not been activated to the greatest extent at this stage.
It is understood that the new LED lamp "Misola" developed by Mitsubishi Electric in Japan is retailed at 680,000 yen (about 44,200 yuan), and the market sales price of Coelux in Italy is 2700-4000 US dollars. The price of sky lanterns produced by most domestic enterprises is as high as about 10,000, and the lowest is between 40,000 and 7,000, and the high price makes people who are eager to experience the blue sky and white clouds indoors prohibitive.
Solving expensive prices has become a key issue in the market promotion of sky lanterns. In an interview with the Aladdin News Center reporter, Ge Weixin, deputy general manager of Changzhou Fengsheng Technology Co., Ltd., said that the original intention of the lamp design was to be accepted by the public. The key to solving the problem lies in reducing the cost of lamps, Fengsheng Optoelectronics has independently developed an optical diffusion plate with Rayleigh scattering effect, directly using the components of existing lamps and lanterns and the existing light sources in the market to produce sky lamps, which have now reached the level of mass production and are close to the people.
Ge Weixin revealed that based on people's needs for the surrounding health environment, it also solves the problem of blue light hazards in current LED products. Since 2019, Fengsheng Technology has used the company's core material technology to carry out research on the design and development and application of sky lanterns, and tracked the most advanced Italian imitation natural lighting system in the world for research, hoping to form a product with Chinese characteristics, master the core technology, can be mass-produced, and close to the people, and improve the popularity of sky lanterns.
During the Guangya Exhibition, Fengsheng will work with partners to display easy-to-install, modular and scalable skylight products with a price range of hundreds to 3,000 in The first large-scale centralized display in China. "The first thing Fengsheng Technology has to do is to solve the problem of starting from scratch in the market, activate the market, and then make the effect of the sky lantern better and apply it more widely through iteration." Ge Weixin said.
epilogue
The development of luminaires is an iterative process. With the advent of the post-epidemic era, health lighting has become an important area for the upgrading and transformation of the LED lighting industry, and it is of great practical significance to promote healthy lighting. As a new lighting product that pays attention to the natural light environment and pays attention to the physical and mental health of human beings, the birth of skylight has provided a new important development direction for the lighting industry. Today, sky lanterns are still in their infancy. However, with the iteration of products and the innovation of technology, sky lanterns will create unlimited possibilities in all application fields, giving light more value space and promising prospects.
