摘要

Provided is an LED light source unit which has excellent heat dissipating performance, prevents an LED from being damaged, is bright and has a long life. The LED light source unit is provided with a printed board, one or more light emitting diodes arranged on the printed board, and an adhesive tape for fixing the printed board on the surface of a heat dissipating member. The LED light source unit is characterized in that the thermal conductivity of the adhesive tape is 1-4W/mK, and the breakdown voltage between the fixing plane of the printed board and the heat dissipating member fixing plane is 1.0kV or more.
