Abstract
A welding apparatus is provided with a lamp unit having a light source such as a halogen lamp and a multiple reflection surface. The light source applies incoherent electromagnetic waves that belong to a visible region and a near-infrared region in which a wavelength is 500 nm (nanometer) or more. The multiple reflection surface reflects and collects the light from the light source in the shape of a desired dot or line. The housing and the transparent cover are superimposed, and the light from the light source is collected by the multiple-reflection surface on the portion where the housing is superimposed on the transparent cover.
Claims9
A welding apparatus for welding a first part to a second part, the welding apparatus comprising:
- a lamp unit including a light source and a multiple-reflection surface,
- wherein the light source applies incoherent electromagnetic waves, and the multiple-reflection surface reflects and collects light from the light source linearly,
- wherein the light of the light source is collected by the multiple-reflection surface on a portion where the first part is superimposed on the second part, and
- wherein the multiple-reflection surface comprises a collecting reflection surface in a cross section in a first plane, and multiple reflection surfaces making up a substantially parabolic reflection surface in a cross-section in a second plane orthogonal to the first plane.
