檢驗led顯示屏質量六大小妙招

Release Time: 2020-07-15

如今LED顯示屏在各個領域應用的范圍不斷擴大,越來越多的場景出現了LED的身影,因此出現了大批廠家為紅利而來,難免會有技術未成熟的廠家混入市場,給客戶帶來極大的傷害。明興光總結6點選屏技巧,輕松讓你選好屏幕。

1.看亮度,就是通常大家所說的你的燈珠能達到多少LM(流明),LM(流明)是衡量燈珠亮度的單位。

2.看芯片和芯片大小,芯片又是燈珠質量好壞的決定因素,一般情況下芯片越大穩定性就越強,亮度就越高,散熱就越好。

3.看膠水和熒光粉,一般好的產品都會用進口膠水,封裝好了的燈珠用手按不變形,質量低廉的膠水一按就會出現變形甚至開裂等現象。

4.看發光是否均勻顏色是否一致,質量的好的燈珠發光很均勻,顏色一致。品質差的燈珠會出現一顆燈珠亮度亮,一顆燈珠暗的現象,發光顏色亂七八糟不統一,會有明顯的暗區。

5.看封裝工藝,質量好的LED燈珠顏色均勻,膠體一致性好。這就離不開好的機器設備,生產機器設備是很關鍵的一個因素,好的設備可以保證產品在各個程序上的穩定性和一致性,保障產品的良品率。

6.看支架,一般情況支架為鍍銀紅銅支架,鍍銀紅銅支架的好處就是散熱快,可以更好的給燈珠散熱,電阻小。市場上有些商家會用陶瓷支架來代替鍍銀紅銅支架,陶瓷支架導熱性能非常優秀。
