The EL line (electroluminescence line) was developed by Israeli and American companies in 1992. It was introduced to the international market in 1997. In 1999, it was produced and sold in small quantities. The annual sales volume was 5 million meters, almost the same year. Pushed to the Chinese market, in 2000, Shenzhen and other electronics companies for the mainland China to sell silk, the main direction to the national market, the market is good, its agent price is ranging from 15 to 20 yuan / m, due to its delivery time Long, unstable channels, strong monopoly, slow after-sales service in the domestic region, the annual sales volume is about 1 million meters.
Landscape lighting in big cities is a very important power project. When power supply is tight, countries are the first to limit the power of landscape lighting, and China is no exception. Research experiments have shown that the use of electroluminescent lines can save 15% of the nighttime decorative power consumption of existing cities. If the electric lighting is changed to energy-saving cold lighting, a lot of energy will be saved.
The research and application of cold light decorative lighting in China is still in its infancy, and the development of energy-saving electroluminescent wire and cable is not suitable for the growing social demand. Therefore, actively developing cold photoelectric cable products and other energy-saving lighting equipment is currently facing the world. One of the important energy conservation topics.
It is expected that market sales will increase and spread at a rate of 100% in the next five years. It is an emerging energy-saving and practical material in the future, and the annual demand is about 5 million to 8 million meters, which is equivalent to the number when Israel, the United States and other companies introduced the market in 1999, showing strong vitality.
Cold light is also a relatively new, wire-like product that acts like a neon, and has its own unique characteristics. It is safer than neon, saves electricity, and does not generate heat. Compared with fiber optic products, it is generally not affected by the length of the light guide. The light is about 30 meters, and the EL cold light can drive about 200 meters with a single drive. Self-organized any pattern or text, and can be exchanged and reused frequently. It is very economical, has many kinds of light colors, soft lighting, long service life, convenient maintenance, extremely light, waterproof, impact resistant, freely bendable, cut, easy to install, and handed over. DC power sharing, low power consumption, no light and environmental protection. The range of EL cold light values ​​has been noticed by some domestic advertising companies, decoration companies and gift companies. As early as two years ago, some optical companies in China were looking for business opportunities.
Since cold light seems to be simple in the production process, many domestic manufacturers have invested in research and development in recent years, or the product quality is not good due to technical problems. Or because the market introduction period is not mature, the market is not easy to lead to the exploration stage. It is understood that there are many domestic manufacturers of LED, EL luminescent film and neon lamps. The main sales of EL wire are concentrated in the developed cities of Jiangsu, Zhejiang and Guangdong.
EL cold light is a new type of phosphorescent technology that provides flexible and flexible illumination with a lifetime of more than 100 million hours. Its specifications are 0.9MM/1.2MM/1.5MM/2.3MM/3.0MM/3.3MM/4.0MM/ 5.0MM, etc., in the temperature of minus 40 degrees - not above 80 degrees in the environment, it requires 110 volts / 500 Hz power supply to illuminate, the market is very strong, and popular.
The artistic design of EL silk is the hand-selected design of interior advertising decoration. In the colorful advertising decoration world, it instantly gives consumers an unforgettable impression, and through the unique design concept of the designer, an artistic concept is ingenious. In addition, the production of fine silk advertising decorations, according to the best brightness level and distribution, the art is presented in front of people, if the lighting is not used properly, or the glare of dazzling makes people feel uncomfortable, then even excellent Advertising works will also lose their artistic style, and even there will be strange phenomena, when our silk thread will play a role, to meet the needs of interior decoration and decoration.
The application of discolored neon lights has a profound impact on the art of lighting. Because the traditional neon tube can only send one color, to change the neon tube in front of the same pattern or text, to achieve the purpose of discoloration. Such overlapping combinations are not only complicated to install, but also have many failure points, poor appearance, strong discoloration and jumping feeling. The EL wire can be produced in different colors, easy to install, easy to disassemble, and softly lit. The lighting of neon signs and logos is undoubtedly a major change that is welcomed by users. It has a unique artistic effect and it feels wonderful and worthy of promotion.
EL wire customer types can be divided into: advertising decoration design, automotive interior company, gift decoration manufacturers, export trade advertising signs.
The electroluminescent line manufacturing method comprises the following steps: the illuminating line comprises a central electrode composed of at least one linear conductor, and the outer surface of the central electrode is covered with an insulating dielectric layer made of an electrically insulating material, and the outer surface of the insulating dielectric layer is covered with fluorescent powder and a luminescent material layer composed of a binder mixture, the outer surface of the luminescent material layer is covered with a transparent conductive layer composed of a nano-scale conductive material having a particle diameter of ≤20 nm, and the nano-scale conductive material constituting the transparent conductive layer also penetrates into the luminescent material layer. In the pores formed by the mixture of the fluorescent powder and the binder, an outer electrode composed of at least one linear conductor is spirally wound around the transparent conductive layer. The method for fabricating the illuminating line comprises a direct coating of the above-mentioned respective structural layers from the inside to the outside and a spiral arrangement of the outer electrodes, wherein the nano-materials automatically fill the pores in the luminescent material layer.

Compared with traditional battery technology, Lithium Battery technology has drawn our attention because of its characteristics of high energy density, long cycle life, light weight and fast charging. Nowadays, they are the common power source for our daily power supply demands, such as golf carts. The volume of a lithium iron phosphate battery of the same specification and capacity is 2/3 of the volume of a lead-acid battery, and its weight is 1/3 of that of a lead-acid battery, and its energy density is several times that of a lead-acid battery.
Lithium batteries can be widely used for a variety of applications, including solar or wind energy storage, solar power system, telecom base station, camping, boat, fishing, recreational vehicles, golf carts and other applications. UFO lithium batteries are ready to be your reliable battery option.
-- Deep depth of discharge. Lithium batteries are designed to last longer with a deep depth of discharge. It enables some electronics such as high-tech and smart devices to work for a longer time.
