Description

Each LED light box includes multiple LED printed circuit boards. Each LED printed circuit board is composed of multiple discretely packaged LED chips.

習知的LED晶粒混合方法是利用震動隨機組合或亂數分選不同類型的LED晶粒(紅光、藍光和綠光)。因此，複數片LED印刷電路板的平均波長會呈現一致，也就是說，複數片LED印刷電路板之間的顏色均勻。 The known LED die mixing method is to use vibration to randomly combine or randomly sort different types of LED dies (red light, blue light and green light). Therefore, the average wavelength of multiple LED printed circuit boards will be consistent, that is, the color between multiple LED printed circuit boards is uniform.

For example, the twelve dies 20 (English codes A~L) of the same wavelength range 30 are randomly placed on the coordinates 111 marked with the number 1 in the square array 11A.

值得一提的是，各方陣11即為單一片LED印刷電路板，矩陣10即為一個LED燈箱，複數個燈箱即為一片LED顯示螢幕。 It is worth mentioning that each matrix 11 is a single LED printed circuit board, the matrix 10 is an LED light box, and multiple light boxes are an LED display screen.

綜上所述，本發明的LED晶粒混合方法能夠利用幻方配合波長區段將不同類型的LED晶粒20(紅光、藍光和綠光)分配位置，因而能夠達成以下功效：其一，複數片LED印刷電路板之間的平均波長呈現一致，使得複數片LED印刷電路板之間的顏色均勻；其二，單一片LED印刷電路板內部的小區域的平均波長呈現一致，使得單一片LED印刷電路板的顏色均勻；其三，該等LED晶粒20不會因為震動混合而受到碰撞並造成損壞。 In summary, the LED chip mixing method of the present invention can use magic squares and wavelength segments to allocate positions of different types of LED chips 20 (red light, blue light and green light), thereby achieving the following effects: first, the average wavelengths between multiple LED printed circuit boards are consistent, so that the colors between multiple LED printed circuit boards are uniform; second, the average wavelengths of small areas inside a single LED printed circuit board are consistent, so that the color of a single LED printed circuit board is uniform; third, the LED chips 20 will not be collided and damaged due to vibration mixing.

以上所述者僅為用以解釋本發明的較佳實施例，並非企圖據以對本發明做任何形式上的限制，是以，凡有在相同的發明精神下所作有關本發明的任何修飾或變更，皆仍應包括在本發明意圖保護的範疇。 The above is only used to explain the preferred embodiment of the present invention, and is not intended to limit the present invention in any form.
