Claims

[Scope of utility model registration request]

(1) A lighting device in which a light-emitting member is provided on a substrate, in which a conductive pattern with a high light reflectance is formed on the substrate near the light-emitting member in a size exceeding that necessary for conduction.

(2) The conductive pattern near the light-emitting member is a conductive pattern electrically connected to the light-emitting member, the width of which is widened near the light-emitting member, as stated in claim (1) of the utility model registration claim. lighting equipment.

(3) The lighting device according to claim 1, wherein the conductive pattern near the light emitting member is separated from the conductive pattern electrically connected to the light emitting member. −
