Abstract
Door Inside Lamp of railway rolling stock is installed on interior of the side doors and illuminated at door opening and closing, isolation and fault. So drivers or passengers can notice the door status visually. In the past, a single color or Bi-color LED Lamps have been using and one ~ multiple lamp was used to implement the feature according to client's requirements. (Example: Total of between 2 and 4 lamps are required for the Warning / Emergency operation / Isolation / Fault.) However these design is not easy to apply if there is the mounting space restrictions and the problems such as rising costs can be caused. In addition, it has vulnerability from point of view aesthetic aspects. Therefore the lamp type has been required that has small size and number of colors in order to resolve these problems. Recently multi LED type door status indication lamp have been developed that can meet the requirements and this lamp has been applied in many railway projects. In this study, I'll introduce the general characteristics and mechanical & electrical characteristics of multi LED type door status indication lamp to help development of this kinds of lamp.
