LED packaging method, LED and LED illuminator

Abstract

The invention applies to the field of illumination, providing an LED packaging method, an LED and an LED illuminator. The LED packaging method comprises the steps of: performing die bonding and wire welding for the LED chips in a same waveband to prepare a batch of LED semi-products; blending fluorescent glue to make the lighting color of the LED semi-products coated by the fluorescent glue same with the color of a sample plate color area from artificial vision; coating the fluorescent glue on the batch of LED semi-products and solidifying the fluorescent glue to prepare a batch of LEDs; and splitting light and color of the LEDs and determining an color area with a color that is same with that of the sample plate color area from artificial vision. According to the embodiment of the invention, in the process of LED packaging, the fluorescent glue is appropriately blended so as to make the lighting color of the LED semi-products coated by the fluorescent glue same with the color of the sample plate color area from artificial vision to split the light and color of the batch of LEDs and determine the color area with a color that is same with that of the sample plate color area from artificial vision, therefor, for the batches before and next, LED chips in different wavebands can be adopted to prepare the LEDs with consistent lighting color.

Description

technical field [0001] The invention belongs to the lighting field, and in particular relates to an LED packaging method, an LED and an LED lighting device. Background technique [0002] In recent years, with the development of society, the LED lighting industry has advanced by leaps and bounds, and the market demand for LED light sources has increased significantly. The supplier's one-time supply has been unable to satisfy those customers who have strict requirements on the color consistency of the LED light source and use a large amount. If the supply is divided into two or more times and the consistency of the luminous color of the LED light source in the front and back batches cannot be guaranteed, the production of this type of customer group will be stagnant, which will indirectly bring huge obstacles to the development of the LED lighting industry. . [0003] Although the traditional technology makes the LED finished products packaged with LED chips of different ban...

Problems solved by technology

[0004] The purpose of the embodiments of the present invention is to provide an LED packaging method, aiming to solve the problem that although the LEDs packaged with LED chips of different wavelength bands in the front and back batches fall into the same color region as the sample light source during light separation and color separation, the luminous color is different from that of the sample. There is a problem that there is a large difference in the emission color of the light source
