Abstract

The invention discloses a capacitance field-induced light-emitting cold light source and further discloses a preparation method of the capacitance field-induced light-emitting cold light source. The capacitance field-induced light-emitting cold light source sequentially comprises an upper sealing layer for protecting a formed cold light source, an upper electrode layer used for ensuring emitting of a front light source and achieving the electric conduction effect, at least one light-emitting layer for emitting a light source, at least one insulating isolation layer for isolating the light-emitting layers and the electrode layers, a lower electrode layer achieving the electric conduction effect, and a lower sealing layer for wrapping the formed cold light source from top to bottom. According to the capacitance field-induced light-emitting cold light source, the average life is 80,000 hours or above, the photoelectric conversion rate is larger than or equal to 95%, the color rendering index reaches 99-100, used materials are free of any pollution, and most of the used materials can be recycled; the structure is simple, firm and light, and external force resistance is extremely good;and the capacitance field-induced light-emitting cold light source is ultra-thin and can be randomly bent, water resistance, moisture resistance and explosion resistance are achieved, the applicationrange is wide, mounting is easy and convenient, transportation is convenient, and the capacitance field-induced light-emitting cold light source can be frequently turned-on and turned-off.

Description

technical field [0001] The invention belongs to the field of energy-saving and environment-friendly technical materials, and in particular relates to a capacitive electroluminescence cold light source and a preparation method thereof. Background technique [0002] Since humans learned to drill wood to make fire, lighting has experienced a development process from fire, oil to electricity. Lighting tools have undergone countless changes, from torches, animal oil lamps, vegetable oil lamps, candles, kerosene lamps to incandescent lamps, fluorescent lamps, and now a variety of decorative lamps, energy-saving lamps, etc. It can be said that the history of lighting is human. Witness to development history. [0003] Currently on the market, the commonly used light source lighting fixtures mainly include incandescent lamps, fluorescent lamps and LED lamps, and their performances are compared in Table 1: [0004] [0005] In view of the requirements for environmental protection...
