HIGH-PRESSURE DISCHARGE LAMP
Document Type and Number:
WIPO Patent Application WO/2018/143300
Kind Code:
A1
Abstract:
An insulator (30) has an open section (34) that enables communication between the outside and a space (s) formed between one side tube section (15) of a light-emitting tube (10) and an insertion hole (23) of a reflector (20), the length (L1) of the other side tube section (14) being greater than the length (L2) of the one side tube section (15). A high-pressure discharge lamp is thereby provided in which cooling efficiency can be increased and luminance can be increased.
