Electro Luminescent (Electro Luminescent) is abbreviated as EL. EL cold light sheet is a physical phenomenon in which the electric field generated by the alternating voltage applied to the electrodes at both ends excites the fluorescent substance to emit light, that is, the electroluminescence phenomenon. Combining a variety of materials to produce a light source of different colors, it has the characteristics of low power consumption, soft light, no ultraviolet rays, diverse colors, long life, and no heat generation. Therefore, it is commonly called cold light source. Cold light source is different from the traditional point or line light-emitting mechanism. It is a uniform and integral surface light-emitting body. It is also a kind of non-damaging and flexible and can be cut. Into an arbitrary complex shape light source.
Introduction:
EL (Electro Luminescent) is abbreviated as EL, which is as light and thin as paper, easy to install, can be disassembled at will, high reusability, low carbon, energy saving, environmental protection, plus unique novel, fashionable and dynamic effects. Therefore, the application of indoor and outdoor advertising will get excellent results. el cold light is a phenomenon in which electric energy is converted into light energy. Because it does not generate heat during the working process, it is commonly called cold light. At present, the industry refers to el cold light films as backlights, light-emitting films, and light-emitting products.

Application range:
Backlit electronics industry:
Computers and computer parts, mobile phones and mobile phone parts, household appliances, LCD projectors, etc., apply EL cold light film to their products to make their products novel, light and thin, stylish, beautiful, energy-saving, and environmentally friendly, thereby adding added value Create additional profits.
Heavy industry:
Automobiles and auto parts, aircraft parts, military and aerospace and other related industries, the above industries directly apply EL cold light film to their products to improve the product level and more beautiful.
Construction and decoration:
EL cold light films of different colors can be used for interior lighting decoration of restaurants, hotels, KTVs, bars, nightclubs, clubs, stage edges, ceiling edges, and bar counters, decorative furniture, house decoration, DIY personal space, company name, The signs of various departments, meeting rooms, lounges, etc., so as to achieve a dazzling, trendy and fashionable effect.
Crafts and commodities:
EL cold light film can be applied to clothing, pants, shoes, hats, bags, glasses, watches and other related products, as well as birthdays, weddings, festivals, anniversaries, celebrations and other greeting cards, gift items, so as to win friends and Appreciation of others.
public Utilities:
EL cold light film can be used to make commercial advertisements, marquee advertisements, ultra-thin light boxes, promotional backgrounds for promotional activities, various signs and backlights for sports events, sports meets, theme activities, parties, speech scenes, and bus stop signs, Fire-fighting nameplates, road signs and road signs, etc., thus reflecting the novelty, ultra-thinness of its products, and modern technology, energy saving and carbon saving.
working principle:
The el cold light film is a device that converts electrical energy into light energy. The working principle is that the particles of the material (Phospher Partides) zinc sulfide are sandwiched between two
The AC electric field driven by the extreme AC voltage, the electrons run at a high speed in the light-emitting layer, activating the light-emitting atoms to be accelerated to obtain sufficient energy, and the electrons excited by the electric field collide with the light-emitting center and the fluorescent material, causing the electron energy to jump. -Change-A physical phenomenon that recombines to cause high-efficiency luminescence, that is, the phenomenon of electrically excited light. The general operating voltage is adjusted within AC40V~AC220V, and the operating frequency can be from 50 Hz to 4000 Hz. Increasing the voltage or frequency will increase the brightness of the el cold light film, but the color of the cold light source will feel blue.
Shelf life:
el cold light film does not suddenly end of life like ordinary traditional light sources. After a long period of use, the brightness of the cold light will gradually decrease. Voltage, frequency, temperature, and humidity are all important factors that affect the life of cold light. .
