  Such straight tube type LED lamps include a lamp including a grounding member provided at one end of the casing so as to protrude outward from the casing. In such a lamp, the ground member is electrically connected to, for example, a conductive base housed in a housing. And, as a method of electrically connecting the ground member and the base, it is considered that a method of connecting via a lead wire is common.

  However, when the ground member and the base are electrically connected via the lead wire, the connection between the lead wire and the ground member and the connection between the lead wire and the base are necessary, which complicates the manufacturing process. There is. Furthermore, there is a problem that the number of parts increases and the man-hour increases.

For example, when a lamp is mounted on a lighting fixture to which a ceiling is attached, it is possible to prevent a base that is a heavy object from falling, and it is possible to improve safety.

  Moreover, it is preferable that the base is formed with a recess that is recessed in the longitudinal direction of the housing, and the tip of the ground member is fitted into the recess.

  With this configuration, the ground member and the base are electrically connected only by inserting the tip of the ground member into the recess that is recessed in the longitudinal direction of the housing. Therefore, the ground member and the base can be electrically connected with a simple configuration. Furthermore, it is possible to prevent the base from being detached from the lighting fixture when the lamp mounted on the lighting fixture is damaged. For example, when a lamp is mounted on a lighting fixture to which a ceiling is attached, it is possible to prevent a base that is a heavy object from falling, and it is possible to improve safety.

The plurality of LEDs 22 are arranged in a line (in a straight line) along the longitudinal direction of the mounting substrate 21. Each LED 22 is a bare chip that emits monochromatic visible light, and is die-bonded on the mounting substrate 21 by a die attach material (die bond material). As each LED 22, for example, a blue light emitting LED chip that emits blue light is used. As the blue light emitting LED chip, for example, a gallium nitride based semiconductor light emitting element made of an InGaN based material and having a center wavelength of 440 nm to 470 nm can be used.

  The sealing member 23 is a phosphor-containing resin containing a phosphor that is a light wavelength converter, and converts the wavelength of the light from the LED 22 and simultaneously seals all the LEDs 22 on the mounting substrate 21 to form the LED 22. Protect. The sealing member 23 has a substantially semicircular dome shape whose cross-sectional shape is convex upward, and is formed linearly along the arrangement direction of the LEDs 22 so as to cover all the LEDs 22 on the mounting substrate 21. In the present embodiment, the linear (stripe-shaped) sealing member 23 is formed closer to one long side than a straight line passing through the center of the mounting substrate 21 in the short direction. The sealing member 23 is formed without interruption from the end surface of one short side of the mounting substrate 21 to the end surface of the other short side. As the sealing member 23, for example, when the LED 22 is a blue light emitting LED, a phosphor-containing resin in which YAG (yttrium, aluminum, garnet) -based yellow phosphor particles are dispersed in a silicone resin in order to obtain white light. Can be used.

  In this embodiment, a blue light-emitting LED chip is used as the LED 22, and a phosphor-containing resin containing yellow phosphor particles is used as the sealing member 23.

  As shown in FIGS. 3 and 4, the base 30 is disposed inside the housing 10 and is fixed to the housing 10. The base 30 is a long plate member for mounting the plurality of LED modules 20, and also functions as a heat radiating body (heat sink) for radiating the heat of the LED modules 20. Therefore, the base 30 is preferably composed of a high thermal conductivity material such as a metal. In this embodiment, a long aluminum base made of aluminum is used. The base 30 is configured such that both ends extend to the vicinity of the grounding cap 50 and the power receiving cap 60, and the entire length thereof is substantially equal to the length of the housing 10.

  A recess is formed on the back surface of the base 30 along the tube axis direction of the housing 10. By forming the adhesive 80 in the recess, the back surface of the base 30 and the inner surface of the housing 10 are bonded, and the housing 10 and the base 30 are fixed. In the present embodiment, the tube axis direction of the housing 10 coincides with the longitudinal direction of the housing 10.

  Further, the surface of the back surface of the base 30 on which no recess is formed is in surface contact with the inner surface of the housing 10. With this configuration, since the base 30 is interposed between the housing 10 and the LED module 20, the heat of the LED module 20 can be efficiently guided to the housing 10. Thereby, the heat of the LED module 20 can be radiated from the outer surface of the housing 10.

  The adhesive 80 is preferably made of a material having a thermal conductivity of 1 [W / m · K] or more from the viewpoint of heat dissipation, and the specific gravity is 2 or less from the viewpoint of weight reduction. It is preferable to use a material. As the adhesive 80, for example, an adhesive made of silicone resin or cement is used.

  In the present embodiment, the base 30 is a secondary mounting board for the LEDs 22. That is, the LED 22 is directly mounted on the mounting substrate 21 that is a primary mounting substrate, and is mounted on the base 30 via the mounting substrate 21.
