Description

FIELD OF THE INVENTION [0001] The present invention relates to a solid composite for phosphor coating and a method for manufacturing the same,

The present invention relates to a solid composite for phosphor coating and a method of manufacturing the solid composite, and more particularly, to a solid composite for phosphor coating processed as a phosphor core using a phosphor in the form of a powder and a method for producing the solid composite for the phosphor coating.

Generally, the phosphor powder is used as a core material of an environmentally-friendly next-generation solid-state lighting obtained through mixed white light, which represents the light source of an LED (light emitting diode) through the excitation and base of the phosphor. Although the phosphor powder is mainly used as a paste form, since the sizes of the constituent particles are different from each other and the shape thereof is different, even though a large amount of solvent and a binder are used, uniformity and efficiency are poor, The yield can not be obtained, and it is more difficult to realize a white LED through mixing of various kinds of phosphors.

Since the emission spectrum of the LED depends on the semiconductor material forming the LED chip, its emission color is limited. Therefore, in order to obtain an LCD backlight or white light for general illumination by using an LED, it is necessary to provide a phosphor suitable for each chip on the LED chip to convert the light emission wavelength. Specifically, a method of installing a yellow phosphor on an LED chip emitting blue light, a method of installing red and green phosphors on a blue LED chip, a method of installing red, green, and blue phosphors on an LED chip emitting ultraviolet rays And the like have been proposed. Among these methods, a method of installing a yellow phosphor on a blue LED and a method of installing red and green phosphors on a blue phosphor are most widely adopted in view of luminous efficiency and cost of the LED chip.

Japanese Patent Application Laid-Open Nos. 5-152609 and 7-99345 propose a method of dispersing a phosphor in a liquid resin for sealing an LED chip as one of concrete methods of providing a phosphor on an LED chip. However, if the dispersions of the phosphors in the liquid resin are not uniform, there is a problem that color deviation occurs for each LED chip.

The use of paste type phosphors is considered to be more limited in the development of ultra - small - sized LEDs for high resolution of screen display devices. New convergence with OLEDs, which are considered as next generation solid state lighting, also deteriorates and new technology development is needed.

Accordingly, the present invention provides a solid composite for phosphor coating capable of uniformly coating single or various phosphors, and capable of increasing the color recall ratio and resolution, and a method for manufacturing the same.

However, the problems to be solved by the present invention are not limited to the above-mentioned problems, and other problems not mentioned can be clearly understood by those skilled in the art from the following description.

A first aspect of the present invention provides a solid composite for phosphor coating comprising a phosphor material and a polymer.

A second aspect of the present invention provides a method for producing a solid composite for phosphor coating, which comprises obtaining a solid composite for phosphor coating by molding heat and pressure on a mixture comprising a phosphor material and a polymer.

A third aspect of the present invention provides a phosphor coating method comprising coating a phosphor layer on a substrate using the solid composite for phosphor coating according to the first aspect of the present invention.

According to the present invention, since a single or various phosphors can be uniformly coated on various substrates, it is possible not only to enhance the color reproduction rate and resolution of the illumination and screen display device, It is possible to realize a design and a coating of a complex pattern structure.
