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.
La présente invention concerne un module de source de lumière DEL dont les performances de dissipation thermique sont excellentes, dont les DEL sont moins endommagées, qui est lumineux et de longue durée de vie. Le module de source de lumière DEL comporte une carte de circuit imprimé, une diode électroluminescente ou plus disposée(s) sur la carte de circuit imprimé, et une bande adhésive servant à fixer la carte de circuit imprimé sur la surface d'un élément de dissipation thermique. Le module de source de lumière DEL est caractérisé en ce que la conductivité thermique de la bande adhésive est de 1-4W/mK, et que la tension de coupure entre le plan de fixation de la carte de circuit imprimé et le plan de fixation de l'élément de dissipation thermique est supérieure ou égale à 1,0kV.
