照明设计整体方案
为追求节能环保，在屋顶上设几个天窗，用漫发射引进自然光，这样光线不仅不会刺伤人眼，而且节能省电。通过使用符合功能要求的光源和调光系统来进一步达到节能的效果。主要采用日光灯，节能灯，个别区域采用金卤灯，泛光照明大部分采用大功率的 LED 灯。其次，整个车站的灯光通过调光系统进行整体集中控制，方便操作。主要区域包括旅客出站层、站台层、售票室、高架候车厅和户外的泛光照明，场景有上午，下午，晚上，节能，阴天等。通过使用邦奇智能灯光控制系统，整个车站的所有灯光组成一个大的网络，在中控室放置一台装有邦奇 DLightⅢ 服务器软件的电脑，人机直接对话，方便用户使用操作。

候车大厅
由于候车厅挑空较高，设计师主要采用了金卤灯。平均显色指数为65左右，光线比较柔和，以确保旅客进入候车厅后有很高的视觉舒服度。这种自然舒适的感觉主要通过采用自然光与环境灯光的有效结合而实现。设计师通过在屋顶开天窗，将自然光有效地引入室内。在天气变化的情况下，邦奇智能照明控制系统可以实现灯光的调节，设有白天，晚上，阴天，节能等场景，以制造舒适节能的室内环境。为满足功能性照明的需要，大厅内的平均照度在500lux 左右。

站台
站台采用大面积自然通风，采光的设计，营造一个让旅客觉得很温馨舒适的氛围。因此在自然光得到最大限度使用的同时，金卤灯也因其发光效率较高而得到使用。金卤灯的平均显色指数为65左右，色温在3000K左右，光线比较柔和，视觉上，给人以舒适的感受。站台平均照度在400lux。

Located in the north central axis of Xian city, North Station is a modern transportation hub for railway, highway and coaches. The architectural style of the station symbolizes the charm of Tang and Han dynasties, and its glorious time. The construction shape of the station has the Tang Ming Dynasty palace and Xi’an city wall elements, the entire building is simple, stately and magnificent. The station comprises of three areas: station building, station, yard and vehicle operation yard. The main station building is 336,600 m2 and with height of 43.6 m. [1]
Lighting design concept
In order to achieve the energy saving goal, the lighting designer of North station decided to have several skylights on the roof allowing natural light to come in through diffuser, so that passengers will not be dazzled by the bright light. More over it also has energy efficient. The use of different sets of light and the dimming system to meet the functional requirements further achieves the energy saving effect. The lighting is mainly fluorescent and energy saving lamps, metal halide fixture is used for individual regions, and using LED as high-power flood lighting. In some parts, the whole of station lighting is centralized control by a dimming system for ease of operation. The controller is pre-set to provide light in areas such as passenger station level, platform, ticketing office, waiting room and elevated outdoor flood lighting, In addition, scenes include morning, afternoon, evening, energy saving, cloudy and so on. By using Dynalite intelligent control system, the whole station forms a large network and a computer installed with DLight III server application is placed in the central control room. The light for the entire station is easily controlled from the server.
Waiting room
The waiting room is a huge area with a high ceiling, metal halide is used with the average color rendering index of 65, combined with natural and surrounding light, it ensures the comfortable feeling of passengers after entering into the waiting room. The skylights on the roof, allow natural light shine into the room. In the case of weather change, Dynalite intelligent lighting control system can adjust the light according to the pre-set modes such as day, night, cloudy, energy saving and so on. To create a comfortable and energy efficient environment, in order to meet functional needs of lighting, the average intensity of the hall is about 500 lux.
Platform
The platform is an open area design aiming at providing a comfortable place for passengers to enjoy natural breeze and day light. Taking the advantage of natural light, the metal halide fixture is also used with the average color rendering index about 65 and color temperature about 3000K, creating a soft lighting environment for the passengers. Average illuminance is 400 lux.
