与国内外同类产品或同类技术的比较情况：

True DC dimming:
Truce DC dimming vs PWM dimming
The average human eye won’t be able to see the flickering PWM dimming. But that doesn’t mean it won’t affect you in any way. Some people are more sensitive to this flicker. And in thesepeople, PWM dimming can lead to eye strain, headaches, and migraines if exposed for long periods of time. This is especially true when the ambient lighting is low.

真正的DC调光：
真正的DC调光vs PWM调光
一般人的眼睛看不到PWM调光所产生的闪烁，但这并不意味着它对你没有任何影响。有些人对此闪烁较为敏感。这类人群如果长时间暴露在这种PWM调光产生的闪烁中，会导致眼睛疲劳、头痛和偏头痛，尤其是当环境光线较低时。

经济评价分析：

As Per IHS, the global market for smart and connected lighting used in commercial applications rose $6.1 billion in 2017 to $7.2 billion in 2018. The market is expected to grow at a compound annual growth rate (CAGR) of 21 percent, reaching about $21 billion in 2022. The global market for residential lighting applications hit $1.8 billion in 2018, while street lighting applications reached $600 million. Competition has slowed for LED lighting component suppliers over the past two years, as global LED production capacity has reached its peak. Over the next five to 10 years, IHS forecasts that growth in general lighting products will remain flat, but LED lighting products are expected to experience promising growth, especially with the commercialization of smart lighting systems.

Dialog is focusing on Commercial lighting product for years, iW380 is a new part which can support the trend of high performance commercial lighting products.

根据HIS报告显示，全球用于商业应用的智能和联网照明市场从2017年的61亿美元增长到了2018年的72亿美元。该市场预计将以21％的复合年增长率（CAGR）增长，到2022年将达到约210亿美元。全球住宅照明应用市场在2018年达到了18亿美元，而街道照明应用市场则达到6亿美元。随着全球LED产能达到峰值，过去两年来LED照明组件供应商的竞争有所放缓。IHS预测，在未来五到十年中，普通照明产品的增长将保持平稳，但LED照明产品有望实现令人鼓舞的增长，尤其是随着智能照明系统的商业化。

Dialog多年来一直专注于商业照明产品，iW380是可以支持高性能商业照明产品趋势的最新元件。
