LIGHT-EMITTING DEVICE

PROBLEM TO BE SOLVED: To provide a light-emitting device for improving heat radiation properties by increasing light output by increasing input power to a light-emitting diode chip. SOLUTION: A channel 21a where a refrigerant made of fluid flows is provided on a packaging substrate 20 in which an LE...

Summary:PROBLEM TO BE SOLVED: To provide a light-emitting device for improving heat radiation properties by increasing light output by increasing input power to a light-emitting diode chip. SOLUTION: A channel 21a where a refrigerant made of fluid flows is provided on a packaging substrate 20 in which an LED chip 10 is packaged. As compared with a case where no channels 21a are provided, heat radiation properties are improved, thus increasing light output by increasing input power to the LED chip 10.
