Embodiment Construction

[0010] According to a preferred embodiment of the present invention, the white light emitting component mainly includes a light emitting component base, one or more blue light emitting components, a lens, and a phosphor composition capable of converting blue light into white light. The light-emitting member can be configured in different forms as required, such as lead type or chip type. Regardless of the form, a base is provided, which has a structure in the shape of a concave cup or groove. The light-emitting component is installed in the concave cup or groove of the base, which is a solid light source capable of emitting blue light with a wavelength of about 430-470nm, such as semiconductor chips including gallium nitride, gallium indium nitride, or aluminum gallium indium nitride. In practical applications, one or more light-emitting components may be used depending on the requirement of illumination brightness. The lens is arranged above the concave cup or the groove, so...

Abstract

The fluorescent inorganic matter for solid light source may be used in matching with gallium indium nitride heterojunction blue solid light source to form white light source. The fluorescent inorganic matter has chemical expression of (Y1-x-y-z-q, Gdx, Dyy, Ybz, Erq, Cep)alpha(Al1-n-m-k, Gan, Sck, Inl)betaO12, where alpha is 2.8-3.2, beta 4.98-5.02, x 0.05-0.65, y 0.0001-0.05, z 0.0001-0.05, q 0.0001-0.05, p 0.01-0.1, k 0.001-0.6, n 0.001-0.45 and l 0.001-0.1. The short wavelength light the blue solid light source emits and the 535-590 nm light the fluorescent inorganic matter emits are mixed to form synthetic white light.

Description

technical field [0001] The present invention relates to a kind of fluorescent inorganic material of luminous solid light source, especially to a kind of luminescent material capable of emitting white light, which utilizes a solid light source of blue light and a phosphor capable of producing yellow light fluorescence upon excitation to produce white light. Background technique [0002] In recent years, the manufacturing technology of solid-state light sources has been continuously improved, and the luminous efficiency has been greatly improved. Because solid-state light sources can emit light waves close to monochromatic, and have the advantages of high reliability, long service life, and wide operating range, they are widely used in many lighting applications. Among them, solid light sources have gradually replaced traditional vacuum bulbs. [0003] In the known technology, there are mainly two common methods of using a solid light source to generate white light. One of th...
