Title:
LAMP HEATING APPARATUS
Document Type and Number:
Japanese Patent JP2017010800
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To uniformly heat an entire surface of a tabular work piece without complicating design of a luminous body or complicating exchange work by properly disposing a plurality of linear luminous bodies in relative to the work piece.SOLUTION: Linear luminous bodies 41-43 are disposed at intervals of distances L2 and L3 in a horizontal direction therebetween at height positions of heights h1, h2 and h3 in a normal direction in relative to a top face WA of a square tabular work piece W. The height h1 is longer than the height h2 and the height h2 is longer than the height h3. Linear luminous bodies 44-46 are disposed at position in bilateral symmetry with the linear luminous bodies 41-43. Between the linear luminous body 41 and the linear luminous body 44, an interval of a distance L1 longer than the distance L2 is provided.SELECTED DRAWING: Figure 2
