与国内外同类产品或同类技术的比较情况：

目前行业中尚未统一调光的相关标准，也没有等级的好坏及区别，造成”可调光”的产品良莠不齐，有些的品牌在某些的指标或效果表现较突出但在某些方面却不尽理想。雷特可调色温智能电源采用T-PWM 数字调光技术加上恒功率程序设计，在各项的指标及效果表现突出，与国内外知名品牌各项指标相比均有明显优势，全面达到行业中高水准：

At present, there is no unified standard for dimming in the industry, and there is no grade of good or bad and distinction,resulting in the “dimmable”products are intermingled. Some brands have outstanding performance in some indicators or effects but not ideal in other aspects. LTECHs color temperature intelligent drivers uses T-PWM digital dimming technology and constant power program design. It has outstanding performance in various indicators and effects.Compared with well-know brands at home and abroad,LTECH has obvious advantages in various indicators,and had reached the high level in the industry comprehensively:

1、市面上大多数的色温电源都是分段式调光，无法做到无级调光；

Most color temperature drivers in the market are segmented dimming,which cannot achieve stepless dimming;

2、市面上大多数的色温电源调光深度≥5%，无法达到或者接近0.1%，而我们的产品通过T-PWM调光技术，下探到0.01%；

The dimming depth of most color temperature drivers in the market is ≥5%, which cannot reach or be close to 0.1%, and our products use T-PWM dimming technology to reach 0.01%;

3、先进的恒功率设计，真正做到调亮度的时候，色温值不变；调色温时，亮度不变；

Advanced constant power design, truly achieve the brightness adjustment, the color temperature value does not change; when the color temperature is adjusted, the brightness does not change;

4、先进的能耗管理技术，待机功耗＜0.5W；

Advanced energy management technology, standby power consumption<0.5W;

5、共阳极设计，同时兼容三线和四线恒流色温灯具，兼容性强，方便升级和改造；

6、DMX512接口带光电隔离，满足最新的的安规标准，更安全可靠；

DMX512 interface with photoelectric isolation, meeting the latest safety standards, more secure and reliable;

7、超低THD，小于10%，减少对电网的干扰，提升用电环境。

Ultra-low THD, less than 10%, reducing interference to the power grid and improving the electricity environment.

经济评价分析：

1、调光的好坏关系到人本照明的品质，好的调光技术促使人造照明更贴近自然照明，满足人们生理及心理需求。因此随著智能照明的发展，搭配好的调光电源的灯具，能够容易得到市场的认同，并可以提升产品的优势、竞争力和价格空间，有极大的经济效益。

2、在节能方面。照明实际使用中，某些情况或场景是下不需要太亮，调光可达到节能效果。由于人眼瞳孔自动缩放，低亮度时瞳孔会放大的原因，人眼感知亮度与测量亮度在低亮度上有明显的差异。举例来说，若想调光至10%，但人眼感知约为32%，有22%的差距仍感觉会太亮。若目标调光至1%，但人眼感知约为10%仍达不到要求，必须真正调到0.01%才会达到人眼感知的1%。雷特调光技术可以深度调光至0.01%，若使用大功率灯具或灯具数量较多时，节能效果非常明显。

3、在照明设计与实际应用中，若以人眼感知的1%开始启动，配合灯光控制系统将灯光渐亮至100%全亮，配上柔细合适的色温改变，就像是自然光的变化，这样的调光及调色温效果完全符合人们对光的要求与期待。

1. The quality of dimming is related to the quality of human-oriented lighting. Good dimming technology promotes artificial lighting closer to natural lighting and meets peoples physiological and psychological needs. Therefore, with the development of intelligent lighting, lamps with a good dimming drivers can easily gain market recognition, and can improve product advantages, competitiveness and price space, which has great economic benefits.

2. In terms of energy saving. In actual use of lighting, certain situations or scenes do not need to be too bright, and dimming can achieve energy saving effects. Due to the automatic zooming of the pupils of the human eye, the pupils will be enlarged at low brightness, and the perceived brightness of the human eye is significantly different the measured brightness at low brightness. For example, if you want to adjust the light to 10%, but the human eye perceives it is about 32%, a gap of 22% will still feel too bright. If the target is dimmed to 1%, but the human eye perception is about 10%, it still cannot meet the requirements, and it must be truly adjusted to 0.01% to reach the human eye perception 1%. LTECH dimming technology can dimming to 0.01% in depth. If high-power lamps or a large number of lamps are used, the energy saving effect is very obvious.

3. In lighting design and practical application, if the start is started at 1% as perceived by the human eye, and the lighting control system is used to gradually light up to 100% full brightness, coupled with a soft and appropriate color temperature change, like a change in natural light, This effect of dimming and color temperature fully meets peoples requirements and expectations for light.
