申报单位： 天津工大海宇照明部品有限公司

综合介绍或申报理由：

此产品应用于轨道交通灯客内照明，通过DALI方案实现了根据车头光感信号自动控制室内照明灯具亮度的功能，通过自动调光使客内亮度在外部亮度改变的情况下始终保持不变。考虑车头与车尾之间的长度，增加了外部亮度变暗客内亮度即刻变亮，外部亮度变亮客内亮度延迟变暗的功能。同时，考虑会车等外部亮度瞬时变化的情况，增加了需要判定外部亮度是否为瞬时变化，从而决定是否需要调节客内亮度的功能。此产品可使客内亮度始终没有突变，提高了乘客在车厢内的舒适度，同时使客内照明灯具不需要一直保持最高亮度，大大的节约了能源。
This product is applied to the passenger interior lighting of rail transit lights. Through Dali scheme, it realizes the function of automatically controlling the brightness of lighting lamps in the class according to the light sensing signal of the front of the car. Through automatic dimming, the brightness of the passenger interior remains unchanged when the external brightness changes. Considering the length between the front and rear of the car, the function of darkening the external brightness, brightening the internal brightness immediately, brightening the external brightness and darkening the internal brightness delay is added. At the same time, considering the transient change of external brightness such as meeting, the function of determining whether the external brightness is transient change is added, so as to determine whether the brightness inside the passenger needs to be adjusted. This product can make the brightness of the passenger always have no mutation, improve the comfort of passengers in the car, at the same time, the lighting lamps in the passenger do not need to keep the highest brightness, greatly saving energy.

2、客内亮度在外部亮度改变的情况下始终保持不变.
3、外部亮度变暗客内亮度即刻变亮，外部亮度变亮客内亮度延迟变暗.
4、需要判定外部亮度是否为瞬时变化，从而决定是否需要调节客内亮度.
1. Dali scheme applied to passenger interior lighting of rail transit light
2. The brightness inside the car remains unchanged when the brightness outside changes
3. When the external brightness becomes dark, the internal brightness becomes bright immediately, the external brightness becomes bright, and the internal brightness becomes dark later
4. It is necessary to determine whether the external brightness changes instantaneously, so as to determine whether it is necessary to adjust the internal brightness

实际运用案例和用户评价意见：

已应用于重庆小单轨地铁客内灯上，得到用户一致好评。

It has been applied to the interior light of Chongqing small monorail subway, and has been well received by users.

是否有“智能设计”？

根据车头光感信号自动控制室内照明灯具亮度。
Yes. According to the light sensing signal of the front of the car, the brightness of the lighting lamps in the class is automatically controlled.
