  The sealing member 43 is a phosphor-containing resin including a phosphor that is a light wavelength converter, and converts the wavelength of the light from the LED 42 and simultaneously seals all the LEDs 42 on the mounting substrate 41 to form the LED 42. Protect. The sealing member 43 has a substantially semicircular dome shape whose cross-sectional shape is convex upward, and is formed linearly along the arrangement direction of the LEDs 42 so as to cover all the LEDs 42 on the mounting substrate 41. In the present embodiment, the linear (stripe-shaped) sealing member 43 is formed closer to one long side than a straight line passing through the center of the mounting substrate 41 in the short direction. The sealing member 43 is formed without interruption from the end surface of one short side of the mounting substrate 41 to the end surface of the other short side.

In addition, about the other structure in the lamp | ramp which concerns on this modification, it is the same as that of the 1st-6th embodiment and its modification.

  In the lamp according to this modification, the inner surface of the translucent cover 810 has an optical function with respect to the light emitted from the LED module, that is, is processed into a shape capable of condensing and diffusing light (for example, an uneven shape). This is different from the lamps according to other embodiments.

  26 may be applied to the entire inner surface of the translucent cover 810 or may be applied to the outer surface of the translucent cover 810.

  As described above, according to the lamp according to this modification, since the optical function is added to the translucent cover 810, the versatility of the lamp can be expanded.

  In addition, the following structure can be considered as another modification.

  In each said embodiment, although the translucent cover was comprised by the substantially semi-cylindrical shape, it is not restricted to this. For example, the translucent cover may have a cylindrical shape in which the main opening is not formed. In this case, at least one end portion of the translucent cover needs to be an open end opening, and the base on which the first holding member and the second holding member are integrally formed is an LED module or a lighting unit. After the circuit or the like is mounted and electrical connection is completed, the base can be inserted from the end opening of the translucent cover and accommodated in the translucent cover.

  Moreover, in said embodiment, although LED was illustrated as a semiconductor light-emitting device, a semiconductor laser and organic EL (Electro Luminescence) may be sufficient.

  In addition, the present invention includes various modifications made by those skilled in the art without departing from the scope of the present invention. Moreover, you may combine each component in several embodiment arbitrarily in the range which does not deviate from the meaning of invention.

  The lamp according to the present invention can be widely used as a lamp or the like replacing a straight tube fluorescent lamp.
