Description
Technical Field
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.
Background
Since the advent, LEDs have been rapidly developed with a great deal of attention paid thereto, and are not distinguished from their own advantages. These advantages are summarized as follows: high brightness, low working voltage, low power consumption, miniaturization, long service life, impact resistance and stable performance. The main schemes for generating white light in the industry at present are: fluorescent glue (yellow powder, red powder, green powder and the like mixed with glue) is packaged on the surface of the blue light single chip through the outer surface, and the blue light single chip is excited and compounded to generate white light. The white light meeting certain photoelectric characteristics needs a certain proportion under the condition that the fluorescent glue material is fixed. The mainstream technology in the industry at present is to combine the proportion of each material in the total material to be used as the proportion of the fluorescent glue, and then adjust the proportion on the basis. For example, a fluorescent glue is composed of glue A (abbreviated as A), glue B (abbreviated as B), red powder 1 (abbreviated as R1), red powder 2 (abbreviated as R2), yellow powder (abbreviated as Y) and green powder (abbreviated as G). The proportion of the powder is equal to A% + B% + R1% + R2% + Y% + G%, when the proportion does not meet the requirement, the weight of some powder needs to be changed according to experience and then converted into weight to form a new proportion, and the new proportion is provided to glue dispensing personnel, and the experience value is indefinite, so that the requirement on technical personnel is high, the proportion is not easy to control accurately, and improvement is needed urgently.
