Description

  The present invention relates to a lamp holder attached to a straight tube type LED lamp to be mounted on a lighting fixture.

  In recent years, LED technology has been remarkably advanced, and high-luminance and wide-use products have emerged. High-luminance LEDs are used as illumination devices as an alternative to fluorescent lamps. And among straight fluorescent lamps, straight tube LED lamps are becoming popular as an alternative to straight tube fluorescent lamps.

  In this straight tube type LED lamp, an LED substrate on which a large number of LEDs as light sources are arranged and mounted on the surface of a long rectangular substrate is housed in a transparent (or translucent) cylindrical housing tube, and electrically connected to the LED substrate. A base provided with two pin-like terminals connected to is fixed to both ends of the storage tube.

  In such a straight tube type LED lamp, since the terminal of the base is the same standard as the terminal of the straight tube type fluorescent lamp conventionally used, the terminal is used as the socket of the lighting fixture for the straight tube type fluorescent lamp. By inserting into the terminal insertion hole and attaching (butt type), or inserting the terminal into the socket groove and turning it about 90 degrees around the tube axis to install (turn-in type) It can be used as well.

  Since this straight tube type LED lamp houses the LED substrate and its control circuit in the housing tube, its weight increases as compared with the conventional straight tube type fluorescent lamp. For this reason, a terminal may remove | deviate from the socket of said lighting fixture, and a straight tube | pipe type LED lamp may fall.

  Therefore, as a means to prevent the straight tube LED lamp from falling, a sandwiching member having a U-shaped cross section that is inserted and sandwiched across the base of the end portion of the straight tube LED lamp, and branches from the center of the sandwiching member There has been proposed a lamp holder in which a socket support portion that presses the outside of a socket of a lighting fixture against the straight tube LED lamp side is integrally formed (for example, Patent Document 1).

  With this lamp holder, the socket of the lighting fixture is pressed to the straight tube LED lamp side, and the straight tube LED lamp is clamped by the clamping member. Rotation relative to the socket is restricted.

  Moreover, since the socket support part always presses the outer surface of the socket toward the straight tube type LED lamp, the axial movement of the straight tube type LED lamp mounted by the above-mentioned butt type can be restricted.
