Infrared LED lamp based on blue light chip exciting phosphor and preparation method thereof

Abstract

The invention discloses an infrared LED lamp exciting phosphor based on a blue-ray chip, and a preparation method of the same. The infrared LED lamp exciting phosphor based on a blue-ray chip includes a lampshade, a cathode column in the lampshade and an anode column in the lampshade, wherein an accommodation space is set in the top end of the cathode column; a blue-ray chip is arranged in the accommodation space; and the blue-ray chip is coated with mixture of phosphor and packaging glue; the phosphor includes 40-70% of nitrogen element, 10-30% of silicon element, and 6-20% of rare earth element by weight. The infrared LED lamp exciting phosphor based on a blue-ray chip does not need to exchange the chip, and only needs to adjust the proportion of the phosphor to obtain the infrared LED lamp with the corresponding wavelength. The preparation method of the infrared LED lamp exciting phosphor based on a blue-ray chip can greatly reduce the manufacturing cost, and can flexibly manufacture an LED lamp being able to emit the infrared wavelength.

Description

technical field [0001] The invention relates to the field of LED lamps, in particular to an infrared LED lamp based on a blue light chip exciting phosphor powder and a preparation method thereof. Background technique [0002] Photoluminescence refers to the luminescence phenomenon caused by exciting luminous bodies with light, and light-emitting devices made of this phenomenon are widely used in people's daily life. [0003] In the prior art, in the process of preparing LED lamps that can emit infrared light, infrared chips with corresponding wavelengths are usually prepared in advance according to the wavelength requirements, and then the infrared chips are used in LED lamps; The wavelength of LED lights is limited, and its emission wavelength is limited by the inherent range of the chip, so it cannot quickly obtain the required wider range of wavelengths; even some wavelengths do not have corresponding chips, the production flexibility is poor, and when required When the ...
