摘要： PROBLEM TO BE SOLVED: To provide an LED light-emitting device capable of easily controlling the outer appearance color of a phosphor layer when light is turned off. SOLUTION: The phosphor layer 13 of the LED light-emitting device 1 has a structure in which a yellow phosphor layer 13a, a red phosphor layer 13b and a blue phosphor layer 13c are sequentially laminated from the side near an LED 10. The thickness and the phosphor concentration of the blue phosphor layer 13c are each set at a value at which when the yellow phosphor layer 13a and the red phosphor layer 13b are excited by an outside light and emit a yellow light and a red light, respectively, the yellow light and the red light do not pass through the blue phosphor layer 43b. As the result, the outer appearance color of the phosphor layer 13 when the LED light-emitting device 1 is lighted off is white as the outer appearance color of the blue phosphor layer 13c. Since the LED light-emitting device 1 emits a white color light and this color matches the outer appearance color of the phosphor layer 13 when light is turned off, the outer appearance quality is high.

摘要： PROBLEM TO BE SOLVED: To make a light emitting diode correspond to a light emitting element which has sufficient heat dissipation and has much calorific value like a light emitting element where a large current flows.
SOLUTION: In the light emitting diode 1, electric power to the light emitting element 2 is supplied from positive and negative electrodes on a lower face and from an unillustrated power source by a plurality of metal bumps 9, circuit patterns 4a and 4b, electrode bonding parts 8a and 8b and power supply circuits 5a and 5b, and the light emitting element 2 emits light. Heat emitted from the light emitting element 2 is transmitted from the two metal bumps 9 to the circuit patterns 4a and 4b, is transmitted to a whole AIN (aluminum nitride) substrate 3 as a ceramic substrate of high thermal conductivity, and is dissipated in air from a heat sink 6. An unillustrated lens system is arranged at a periphery of the light emitting element 2, and light radiated from a light emitting face of the light emitting element 2 is condensed.

摘要： PROBLEM TO BE SOLVED: To further improve efficiency of an LED light-emitting device emitting white light. SOLUTION: The LED light-emitting device shown in Fig. 1 includes an LED 10, a red light-emitting R phosphor layer 11, a yellow light-emitting Y phosphor layer 12, and a blue light-emitting B phosphor layer 13. The phosphor layers are stacked in the sequence of the Y phosphor layer 12, the B phosphor layer 13, and the R phosphor layer 11 from the side close to the LED 10. The stacking sequence of the Y phosphor layer 12 and the B phosphor layer 13 is first determined to prevent these layers from interacting with each other, and the stacking sequence of the R phosphor layer 11 and the Y phosphor layer 12 and the stacking sequence of the R phosphor layer 11 and the B phosphor layer 13 are determined by a determination expression D. By determining the stacking sequence like that, degradation of the conversion efficiency of the phosphors due to concentration quenching can be considered, the emission efficiency of the LED light-emitting device is improved.
