Title: Explosion-proof filter, light equipment equipped with it, projector equipped with it and manufacturing method of explosion-proof filter
Inventor: MOMOSE AKIRA
IPC: F21Y101/00
Filed: 2002-08-09
Abstract: <P>PROBLEM TO BE SOLVED: To provide an explosion-proof filter having strength capable of sufficiently preventing dispersion of fragments to the outside even if a light source lamp is accidentally exploded, and capable of providing a high open area ratio.  <P>SOLUTION: A partition part 560A for partitioning a passage into a plurality of sections is formed over a predetermined length along a cooling passage D, and the end face of the partition part 560A is shaped into a mesh-like form to form this explosion-proof filter 560. By shaping the end face of the partition part into the mesh-like form to reduce the sizes of openings, the fragments are prevented form dispersing to the outside through the opening. By forming the partition part 560A over the predetermined length along the cooling passage D, so that the strength of the filter itself can be increased, cooling air flowing through the cooling passage D is hardly blocked by the partition part 560A, and the open area ratio can be increased.  <P>COPYRIGHT: (C)2004,JPO
