Embodiment Construction

[0026] Preferred embodiments of the present invention will be described in more detail below with reference to the accompanying drawings.

[0027] Fig. 1 is a cross-sectional view of a light emitting device of the present invention. As shown in FIG. 1 , the light-emitting chip 10 is used as a light-emitting source, which can emit a wavelength of 250nm after being acted on by electrodes? The light between 420nm, that is, the luminescent light source emits ultraviolet light. The organic fluorescent layer 20 is made of one of the following organic polymers (divided into the first type, the second type and the third type) are formed on the light emitting surface 12 of the light emitting chip 10, and the thickness of the organic fluorescent layer 20 is preferably controlled at 500? ? 5000? Among them, the thickness can also be determined according to the needs of the designer. The organic fluorescent layer material is the following organic polymer:

Abstract

This invention relates to one light device to generate visible light, which comprises the following steps: one light chip to send purple light and ultraviolet light with wave length for 250 nm-420nm; one organic fluorescence layer to make organic polymer through vacuum coating, network print and plane printing and splashing, casting to form light chip surface; one sealing layer with multiple nanometer transistor, wherein, the light energy is of organic laser layer to send one second light for 380nm-800nm for mixing to form one mixture light.

Description

technical field [0001] The present invention relates to a light-emitting device, more particularly, the present invention relates to a light-emitting device that generates visible light, which is composed of red, yellow-green, and blue phosphors in different proportions excited by ultraviolet light-emitting diodes. Organic fluorescent layer, and by mixing light, it can produce visible light such as white light, red light, green light, blue light, yellow light, orange light, indigo light, or purple light with excellent uniformity and color rendering. Background technique [0002] There are many types of light-emitting diodes, which can be divided into two types: visible light-emitting diodes and invisible light (infrared light, ultraviolet light) light-emitting diodes according to the wavelength of light. Generally, visible light-emitting diodes are used in digital clocks, bank exchange rate billboards, traffic signs, outdoor information billboards, etc. Invisible light-emit...
