Analysis of internal LED vehicle lights (1)

Commonly used internal LED vehicle lights are down lights, reading lights, door lights, stepping lights, instrument lights, dashboard warning lights, etc.

 

Cars and trucks are generally set up one down light. In addition to the function of internal decoration, LED Down Lights can monitor car doors and keep on lighting when doors are not closed (just like a visible alarm). The general power consumption of LED down lights is 0.5W-2W. LED Down lights for buses need higher power consumption (2W-3W). In addition to the higher light condensation, another advantage of LED down lights compare with commonly used energy-saving down lights is that LED down lights have a stronger cooling function.

 

Commonly used internal LED vehicle lights are dome lights, reading lights, door lights, stepping lights, instrument lights, dashboard warning lights, etc.

 

Reading lights, as its name implies, typically used to make driver or passengers more convenient to read word materials. LED reading lights are installed in the front of crew seat, less than 50 cm from the user’s head, usually with a 45 degree angle. A certain degree of light condensation is required by these lights, since a higher light condensation will reduce the blindfold reaction of readers. Normally, LED reading lights have a small beam angle, not very high lamp flux, some of them can be manually adjusted. Users can adjust the lighting angles and lighting intense by pressing buttons beside the light. LED reading lights are one of commonly used internal LED vehicle lights. The general power consumption of LED down  lights is around 5W. Similar to LED downlight, LED reading lights have a better cooling function. This advantage is obvious in the condition of long-time lighting. Users no longer need to sweat to view the map in hot days.

 

LED door lights are lights in between internal LED lights and external LED lights. However, people used to classify them as internal LED vehicle lights. They are typically installed in the bottom of internal car doors. When door is open, LED door lights will be lightened, emitting a red light to attract other pedestrians and drivers attention, avoiding accidents. When door is closed, they will go out.

 

LED stepping lights are only installed in large and medium-sized buses, rarely appeared in small cars. It is a kind of lamp with service function. When passengers intend to get on or get off bus or couch during the night, LED stepping lights will be lightened.
