Description

  The present invention relates to an illumination device using an LED as a light source, and more particularly to a structure of an LED illumination device that can be attached to a fluorescent lamp luminaire.

  In recent years, a light emitting diode (LED) is used as a light source as an alternative to a fluorescent lamp that generates ultraviolet rays inside a glass tube and a fluorescent material previously applied to the inner wall of the glass tube converts ultraviolet rays into visible light. Practical use of lighting devices is underway. Advantages of a lighting device using an LED as a light source include a longer life and energy saving than when a fluorescent lamp is used.

  If an example is explained in full detail about the illuminating device using LED for a light source, it will be provided in the tube which is a tubular body formed with a transparent material, and it will be installed in the tube so that a plurality of LEDs may be arranged in parallel on one side, A circuit board provided with two connection terminals projecting from both ends of the tube, two caps fitted to both ends of the tube, and attached to the inside of the cap, and provided with a pair of internal connectors on the inside, There is known an illuminating device including an external connector and a power supply circuit in which the external connector protrudes through the cap (Patent Document 1).

Utility Model Registration No. 3154200

  The LED lighting device configured as described above can emit a plurality of LEDs by inserting an external connector into the insertion port of the fluorescent lamp lighting fixture. However, according to the LED illumination device shown in Patent Document 1, since the power supply circuit is housed inside the cap provided at both ends of the tube from which the LED emits light, the cap portion becomes long, and the portion that emits light from the LED There is concern about shortening. That is, the length of the illuminating device is determined by the JIS standard so as to be attached to the luminaire, and according to the illuminating device shown in Patent Document 1, the length of the cap that does not transmit the light of the LED becomes long. There is a risk that the range of light will be narrower than the lamp.

  The present invention has been made in view of the above-described points, and the object of the present invention is to make it possible to easily replace the power supply circuit while maintaining the light emission range of the LED in the same manner as a conventional fluorescent lamp. The object is to provide a lighting device.

  The LED illumination device according to claim 1 is a frame having a substantially D-shaped end face formed integrally with a curved surface portion and a flat portion, an LED substrate on which LEDs serving as light sources arranged on the flat portion are disposed, and A cover body having a substantially arcuate end surface assembled to the frame, a power supply circuit for causing the LED to emit light, a holding member for holding the power supply circuit, and a holder for holding both ends of the frame and the cover body An LED lighting device having a member and a base fixed to the holder member as main components, wherein a holding member storage portion in which a power supply circuit is held in a space formed by a curved surface portion and a flat portion of the frame And a notch is formed in the flat portion of the frame end, and the holding member is provided with a protrusion that engages with the notch.

  The LED illumination device according to claim 2 is the LED illumination device according to claim 1, wherein the holding member has a substantially half-pipe shape in section having an opening for attaching a power supply circuit. It is characterized by that.

  An LED illumination device according to claim 3 is the LED illumination device according to claim 1 or 2, wherein the frame and the power supply circuit are prevented from electrical contact. An insulating sheet is provided, and the insulating sheet is provided with a through hole that is fitted into the protrusion of the holding member.

  According to the configuration of the present invention as described above, the LED board on which a plurality of LEDs are arranged is arranged on the flat part of the frame, and the holding member is the space of the frame formed by the curved surface part and the flat part. Since the power supply circuit held in the housing is housed, it is possible to keep the light emission range by the LED as in the conventional case. In addition, since the protrusion of the holding member stored in the storage unit is engaged with the notch formed in the frame end, the holder member that holds the frame and the end of the cover body is removed, and the frame is stored. By pulling the protrusion of the holding member housed in the portion, the holding member can be pulled out from the frame, and the power supply circuit held by the holding member can be easily replaced.
