Abstract
A light source device includes: a substrate having a front surface on which a light-emitting diode is mounted; and a case having a bottom plate that holds the substrate, wherein a driver circuit for driving the light-emitting diode is mounted on a rear surface of the substrate that is opposite to the front surface thereof, wherein an opening corresponding to a size of the light-emitting diode is formed in the bottom plate of the case, wherein the front surface of the substrate is fixed to a rear surface of the bottom plate of the case from outside of the case with the light-emitting diode fitted in the opening, and wherein a coating material with an emissivity of equal to or higher than 0.9 and equal to or lower than 1.0 is applied to an outer surface of four side walls of the case.
Claims9
A light source device, comprising:
- a substrate having a front surface on which a light-emitting diode is mounted;
- and
- a case having a bottom plate that holds said substrate, the case further having four side walls constituting an outer frame that is perpendicular to the bottom plate,
- wherein a driver circuit for driving said light-emitting diode is mounted on a rear surface of said substrate that is opposite to the front surface thereof,
- wherein an opening corresponding to a size of said light-emitting diode is formed in the bottom plate of said case,
- wherein the front surface of said substrate is fixed to a rear surface of the bottom plate of said case from outside of said case with said light-emitting diode fitted in said opening, and
- wherein a coating material with an emissivity of equal to or higher than 0.9 and equal to or lower than 1.0 is applied to an outer surface of the four side walls of said case.
