Method suitable for calculating proportion of fluorescent glue in LED packaging

Abstract

The invention relates to the technical field of LED processing, in particular to a method suitable for calculating the proportion of fluorescent glue in LED packaging. The method comprises the following specific operation steps: red powder proportion: when a color zone shifts longitudinally, only R1 / ALL = (R1 + R2) / (R1 + R2 + Y + G) value is adjusted; the rubber powder proportion, when the color zone deviates in the horizontal direction, only the S / P = S / (R1 + R2 + Y + G) value is adjusted; the high-wave red powder proportion: when R9 is low, only the R2 / R1 value is adjusted; and the specificgravity of the green powder in the yellow-green powder: when the CRI is low, only the G / (G + Y) value is adjusted. Each factor in the proportion calculation is combined with the specific photoelectriccharacteristics, so that the proportion calculation is simpler and more effective; the formation of a proportioning EXCEL calculation table, proportioning software and a related database is facilitated; the method is convenient for summarizing the proportion regularization, reduces the dependence on the experience of technicians, greatly reduces the proportion management difficulty, and is higherin practicability.

Description

technical field [0001] The invention relates to the technical field of LED processing, in particular to a method suitable for calculating the ratio of fluorescent glue in LED packaging. Background technique [0002] Since the advent of LED, it has been widely valued and developed rapidly, which is inseparable from its own advantages. These advantages are summarized as follows: high brightness, low operating voltage, low power consumption, miniaturization, long life, impact resistance and stable performance. At present, the main scheme for generating white light in the industry is: the surface of the blue light single chip is encapsulated with fluorescent glue (glue mixed with yellow powder, red powder, green powder, etc.) To achieve white light that meets certain photoelectric characteristics, a certain ratio is required when the fluorescent glue material is fixed. At present, the mainstream technology in the industry is to combine the proportion of each material in the to...

Then its ratio is equal to: A%+B%+R1%+R2%+Y%+G%. When this ratio is not met, it is necessary to change the weight of certain types of powder according to experience, and then convert it into weight , form a new ratio, and give it to the glue blending personnel. This kind of experience value is uncertain, and the requirements for technical personnel are relatively high, which is not conducive to the precise control of the ratio, and needs to be improved urgently.
