A semiconductor light-emitting device has a substrate, one or more semiconductor light-emitting elements provided on the substrate, and that emit light having a peak wavelength in a 380 nm to 480 nm wavelength region, and a molded member covering the semiconductor light-emitting element, and containing a phosphor that emits visible light by being excited by the emitted light from the semiconductor light-emitting element. The molded member is formed so that index A=H/(s/n) satisfies 0.3&#x2266;A&#x2266;6, where H is the height [mm] of the molded member from the substrate, s is the square root [mm] of the contact area between the substrate and the molded member, and n is the number of the semiconductor light-emitting elements covered with the molded member.

Semiconductor light-emitting device

In a light emitting module, a red phosphor is contained in a second phosphor layer so that the wavelength of a second phosphor layer after the wavelength conversion is longer than that of a first phosphor layer. And a blue phosphor and a yellow-green phosphor are contained in the first phosphor layer. The first phosphor layer is formed in an illumination area of light emitted from an LED chip, and the first phosphor layer converts the wavelength of the light from the LED chip and emits the wavelength-converted light from an emission surface. A part of the second phosphor layer is formed in a non-direct area where no light is illuminated from the LED chip and where light is illuminated from the first phosphor layer. The part of the second phosphor layer formed in the non-direct illumination area converts the wavelength of the light emitted from the first phosphor layer.

A light-emitting device () including a light-emitting element (), a first phosphor (), and a second phosphor (). The light-emitting element () emits light Lhaving a wavelength range within the visible region. Upon receipt of the light L, or light Loriginating from the second phosphor (), the first phosphor () emits light Lhaving a wavelength range, which differs from that of the first light Land the third light L, but falls within the visible region. Upon receipt of a specific wavelength component (ultraviolet light, or the like) included in external light, the second phosphor () generates the light Lwhose wavelength range is substantially the same as that of the light L, thereby radiating the first phosphor () with the light L
