Light sources for lighting organic electroluminescence (OEL) plants and manufacturing method thereof

Abstract

The invention relates to a light source for lighting organic electroluminescence (OEL) plants. In the method, a light-conversion-light function layer is added to the outer surface of a glass substrate of an OEL light source, so that a part of incident light of the OEL light source transmitting the light-conversion-light function layer is converted into red light with wavelength of 600-680nm. The manufacturing method of the light source for lighting the OEL plants refers to manufacture the light-conversion-light function layer with hollow patterns on the outer surface of the glass substrate. In the invention, a light-conversion-light array is utilized to regulate the emitting proportion of a blue light peak area to a red light peak area of an organic light-emitting diode (OLED) lighting device, thus realizing an approximately-even area source. The manufacturing method is utilized to improve the radiation of the blue light area and the red light area required by plant growth. The light source can stably light for a long time, are environmentally friendly, can grow the plants quickly, can ensure human health, and is an novel efficient, energy-saving and environmentally-friendly light source for plant growth.

Description

technical field [0001] The invention relates to a light source for organic electroluminescent plant lighting and a manufacturing method thereof, belonging to the technical fields of plant growth regulation and optoelectronics. Background technique [0002] At present, sunlight is mainly used as a natural light source in the market, and the sunlight passes through the light conversion agent plastic film to obtain the luminescence spectrum of the two peak regions respectively. The color conversion plastic film is doped with an organic or inorganic light conversion agent during the production process, such as an organic conjugated molecular fluorescent light conversion agent method, which can convert the green light in sunlight into red light and the main peak of the emitted light is 600 nm; single-base dual-energy rare earth light-converting agent method, which has the performance of simultaneously absorbing ultraviolet light and green light and emitting blue light and red lig...

Problems solved by technology

[0005] However, the existing process and structure of using LED or organic electroluminescent light source to produce blue-violet light and red-orange light are relatively complicated, the light utilization efficiency is affected, and the cost is also high.

The light source for organic electroluminescent plant lighting can place an organic thin film layer composed of organic compounds with a specific thickness between the anode and cathode of the organic electroluminescent element, and use some special device structures to achieve double emission matching plant growth peak spectrum, but the manufacturing process of adding a functional layer inside the sealed cover formed by the glass substrate and the cover of the OLED device is more complicated and the cost is higher
