【应用】LED驱动芯片SGM3758、SGM3759助力暗光自拍解决白光LED闪光灯色温不准、亮度不均难题

时间： 2018-10-29 来源：SGMICRO

技术问答

随着智能手机的普及和发展，其内部各项零件都在发生着巨大变化，比如，主芯片内增加了GPU、NPU等高端辅助芯片，屏幕也从蓝屏、LCD屏发展到现在全面普及的OLED屏，而手机闪光灯也经历了从无到有的过程。

目前，大多数手机使用LED闪光灯作为布光和补光来解决手机拍照光线不足的问题。其原因是因为LED闪光灯具有体积小、低功耗的特点，能够嵌入到越来越轻薄的手机中，并节省电力。

但是，随着人们对手机拍照质量的需求不断增加，白光LED闪光灯色温不准、亮度不均等问题逐渐显露。虽然氙气灯具有更好的亮度，效果均匀，也能够发出非常接近太阳光色温的光线，但它的成本高，体积大的明显问题注定了氙气灯不会成为手机闪光灯应用的主流产品。

面光源-屏幕布光专利

分屏组成布光区、过渡区、预览区，真正柔和布光，圣邦微电子（SG Micro）自有专利方案，对用户开放，防范专利侵权风险，经济、安全、可行。根据补光强度需求，改变布光区面积，自由调整预览区大小。

专利号：201610656426.1

业内最强大电流设计

1、5倍电流设计，惊人的屏闪照度，堪称业内最强；100us内稳定输出或关闭，闪光同步更完美！

2、LED超规格大电流闪光应用—控制时间是关键。

普通背光LED，一般额定恒流电流仅30mA，但峰值电流可以达到100mA，然而需要严格控制时间。LED灯芯发热时间常数350ms，低于这个时间，没问题！

普通背光LED的闪光冲击压力试验：100mA/200ms 10W次冲击 OK！

ON/OFF试验结果总结

结论：选择JF-S206灯珠分别做2个ON/OFF试验，其结果的电性参数与光学参数均在标准范围内，没有出现异常。

备注：样品测试都在实验结束后1Hr内完成；试验结果VF变化率在±3%以内，IR小于0.2μA判定为正常；试验结果Φ变化率在±3%以内，XY变化率在±0.005内判定为正常。

3、SGM3758/SGM3759特有的320ms累计计时Timer，支持连闪，有效保护LED免招损坏。

【选型】国产LED驱动芯片SGM3752可P2P替换SY7200A应用于温控器，最大输出电压达35V

温控器目前非常广泛的用在办公室，商场以及小家庭里面，可以很方便的控制中央空调。温控器是通过LCD面板来显示温度等相关信息的，LCD本身不会发光，要想让其显示所要的数据，需要使用白光背光源，白色背光源一般由数个发光白色LED灯组成，LED灯的个数由屏的尺寸大小决定，要使LED灯亮，还要使用LED驱动芯片。
