And in the above-described embodiment, what framework 10 adopted is the tubular article of non-Splittable, but also can adopt Splittable.For example, can be formed by light transmission cover and base station the framework (peripheral device) of an elongated tubular.In this case, as the light transmission cover that covers LED module 30, the slightly translucent resin cover of semicircle tubular can be adopted, as base station, the half-terete metal base station with flash structure can be adopted.Because this metal base station adopts the formation of exposing at the face of the contrary side of face with mounting LED module 30, therefore the heat of LED module 30 directly can be rejected heat to the outside of lamp from metal base station.And, as base station, can not be also metal base station, but adopt the resin base station being formed by resin.

And in the above-described embodiment, although LED element 32 by blue led chip and yellow fluorophor, formed, but be not limited by this.For example, in order to improve color rendering, also can on the basis of yellow fluorophor, further sneak into red-emitting phosphors or green-emitting phosphor adding.

And, in the above-described embodiment, although what LED element 32 adopted is the White LED element of B-Y type, but also can not adopt yellow fluorophor, but adopt contain red-emitting phosphors and green-emitting phosphor containing fluorophor resin, thereby and by these and blue led chip portfolio being emitted to the formation of white light.And LED chip also can adopt the LED chip of the light that sends blue color in addition.For example, in the situation that the LED chip of ultraviolet is sent in employing, as fluorophor particle, also can combine sending the fluorophor particle of each color of three primary colors (red, green, blueness).And can adopt the wavelength shifter except fluorophor particle, such as adopting semiconductor, metal complex, organic dyestuff, pigment etc. to contain the light that can absorb certain wavelength as wavelength shifter, and send the material of material from the light absorbing with the light of different wavelength.

And, in the above-described embodiment, as light-emitting component, show for example LED element, but be not limited by this.Electroluminescent) or other the solid-state light emitting element such as the EL element such as inorganic EL such as also can adopt the semiconductor light-emitting elements such as semiconductor laser or organic EL (Electro Luminescence: as light-emitting component.

In addition, in the situation that not departing from purport of the present utility model, the various distortion that those skilled in the art can be expected are executed in the formation of present embodiment and variation, or the formation after the inscape in embodiment and variation is combined is all included in scope of the present utility model.
