The Department of diagnosis and treatment is the center of the hospital, so we should consider the function of the hospital in a comfortable environment. Because the practice of this part is in the daytime, so we should consider the illumination balance of the natural light from the gate to the room on the first floor, which is only illuminated by artificial light.


Public hall

The public hall is the central area of the most frequent flow of personnel, which is connected with the consulting room, the corridor, the staircase and so on. If the public hall is the atrium in the form of lighting, mainly used gas discharge lamp, the atrium should deal with natural light and artificial lighting smooth transition, prevent the atrium around the corridor illumination is too low, and the gap is too large and cause visual discomfort.


Natural lighting less sharing hall space to install lighting to consider maintenance and maintenance, using a small light wall installed in the hall corridor side, standing on the corridor side to maintenance personnel can touch lamps, it is convenient for maintenance, easy to adjust the light angle, soft light can evenly illuminate the hall space. Registration, fees, laboratory services window and outdoor lighting should be bright, because the documents and the cost of the medical staff and the patient or family members need to check and verification of the handover.

The ward is different from the public walkway door emergency medical building, inpatient for quiet environment, the lights should be uniform and soft. Therefore, the illuminance is relatively low, usually around 50lx. It is appropriate to use embedded warm color light lamps or small compact fluorescent lamps. The aisle of each ward door consists of a footlights for nurse patrol at night, the night will be closed for general lighting.


The safety passageway of the public passageway, the safety exit sign lamp should be installed above the doorway leading to the outdoor or safety staircase, and the evacuation sign lights should be installed at the corner of the long lane, and the distance between the evacuation signs should be equal to or less than 20m.


Diagnosis and treatment room

The horizontal illumination and vertical illumination of the diagnosis and treatment room should meet the requirements of the doctor's observation and writing, and the illuminance should generally be above 300lx. In addition, the natural lighting better diagnosis and treatment room should be installed blinds, indoor layout should also avoid the summer season sun direct radiation of important equipment.


In the therapeutic room, the colder color index should be equal to or higher than 80 of the light source for spirit and attention. In addition, considering that the patient may face up and lie on the hospital bed, we should avoid direct glare in the vision of the supine patients in the design. Therefore, we should choose a reflective thin diameter straight tube fluorescent lamp with a light shield.


Examination Room

The examination of the illumination of the body part can be considered in the same way as the general chemical laboratory. But considering the color rendering of the light source, even if the efficiency is low, it should meet the requirement of light color. It is also important to consider how to make the patient feel safe and relaxed in the physiological examination room, which is the object of the patient.


Radiographic room

The studios concerned with radiation do not require too high illumination, but need to be dimmed. X light perspective room in mechanical maintenance and adjustment is the need for 200lx illumination. In the perspective phase, 50lx is required to get in and out of the room. The foot switch can be used in perspective, and the red light is transferred from 20lx to zero.


Inpatient Ward

Room lighting, general illumination for 100-200lx, it is necessary to make up or not to lie by patients feel glare. A single ward or a double ward can be installed on the wall of the bed.


For the six beds, when the beds are arranged in two rows, the lamps and lanterns are mostly placed in the center of the room, which is necessary for the location of patients' eyes and the lighting of lamps and lanterns. General lighting is expected to be dimmed at the two level. In addition to general lighting, at the bedside to install for reading and arrange daily life bedside lamp.

The operating department is a relatively narrow place without windows and continues to work for a long time. So the lighting of the operation room must be considered to reduce the fatigue of the people concerned. In the range from the operation room to the preparation room, the general illumination is high, which requires the good diffusivity, the cover, the structure and the dust.
