AI Technical Summary

Problems solved by technology

However, its structural design is relatively complicated, which leads to cumbersome manufacturing process and high cost. Moreover, the white light produced by it has a low color rendering index, a relatively short lifespan, and large dispersion of color areas. It is difficult to ensure product quality and meet the requirements of mass production.

Abstract

The invention discloses a preparation method of a warm white diode, which comprises the following steps: 1) preparing raw materials; 2) weighing and proportioning; 3) preparing fluorescent glue; 4) injecting glue; 5) roasting; and 6) obtaining the finished product: obtaining the finished product of the warm white diode after the roasting step is finished. The invention also discloses a diode implementing the preparation method of the warm white diode. The method provided by the invention is simple in manufacturing process and low in cost, ensures the product quality and meets the requirements of large-batch production; the diode provided by the invention has a simple structure and a small volume, is flexible to use, realizes reasonable proportioning of the fluorescent glue, can improve the centrality of a white color area, the color rendering index and the luminous flux and reduce the discreteness, greatly prolongs the service life and realizes a good decorative effect. Test shows that the color rendering index is more than 75, the color temperature can be controlled at 1,900-2,100 K, and the needs of massive users can be met.

Description

Technical field [0001] The invention belongs to the field of diodes, and particularly relates to a method for preparing a warm white light diode and a diode manufactured by the method. Background technique [0002] Diode (Light Emitting Diode, referred to as LED) is a component made of semiconductor materials. Because it can convert electrical energy into light, it is a kind of fine solid-state light source. It not only has small size, long life, and low driving voltage. , Fast reaction rate and excellent shock resistance, and can meet the design needs of light, thin, short and small, and are widely used in various products in daily life. The blue chip and the phosphor are mixed and energized to emit white light, which will gradually replace incandescent and fluorescent lamps in the future. This semiconductor white light has the advantages of small size, long life, energy saving, and no heavy metals such as mercury polluting the environment. Flexible use. It can be widely used...
