Description

  The present invention relates to a straight tube fluorescent lamp type LED illuminator in which LED elements are arranged.

  A conventional straight tube fluorescent lamp uses a glass tube as a fluorescent tube, and a high-pressure discharge is performed in a mixed gas of argon gas and mercury vapor enclosed in the glass tube, so that ultraviolet rays generated from the mixed gas can be It uses the principle that the fluorescent material applied to the inner surface of the glass tube is illuminated and the fluorescent material emits white light. The lighting fixture uses a pre-starting ballast or inverter that uses a glow starter to turn on the fluorescent lamp. It consists of a system ballast. Here, an object in which a straight tube fluorescent lamp is attached to a lighting fixture is referred to as an illumination device.

  Recently, a straight tube fluorescent lamp type LED illuminator in which an LED element is mounted as a light source has been commercialized, and the direct tube fluorescent lamp of the lighting device is increasingly replaced with a straight tube fluorescent lamp type LED illuminator. In the background of the use of the straight tube fluorescent lamp type LED illuminator, the straight tube fluorescent lamp type LED illuminator generates a direct current power source from an alternating current power source to light the LED element of the light source, and the low voltage of the direct current power source. This is because the lighting control can be easily performed with a low power consumption and the long-term reliability is high such that the non-lighting due to the disconnection of the filament is difficult. In addition, since a discharge is not performed, it is possible to use a glass tube that is easily damaged and replaced with a resin or the like, and is excellent in impact resistance. Further, a straight tube fluorescent lamp type LED illuminator using an LED element driven by an AC power source has been developed.

  When replacing the straight tube fluorescent lamp of the lighting device with a straight tube fluorescent lamp type LED illuminator, after removing the straight tube fluorescent lamp, directly connect it to a lamp fixture that has two insertion sockets with spring members inside facing each other. Insert the power supply connection terminal at one end of the tube fluorescent lamp type LED illuminator into the terminal hole provided in one insertion type socket, and push the straight tube fluorescent lamp type LED illuminator in the insertion direction while inserting the power supply connection terminal at the other end The operation of attaching the straight tube fluorescent lamp type LED illuminator is completed by being inserted into the terminal hole of the other insertion type socket.

  In this work, when the power is supplied to the lighting fixture without turning off the power switch for turning on / off the lighting device, the straight fluorescent tube type LED illuminator is attached to the lighting fixture. There is.

  In the above case, the lamp fixture has a structure in which power is supplied from the respective terminal holes of the two insertion-type sockets arranged facing each other, so that the straight fluorescent lamp type is connected to the terminal hole provided in one insertion-type socket. When the power connection terminal at one end of the LED illuminator is inserted, a voltage is applied to the straight tube fluorescent lamp type LED illuminator, and the other end of the straight tube fluorescent lamp type LED illuminator is inserted into the terminal hole of the other insertion type socket. When inserting the power connection terminal, there may be a case where the power supply connection terminal at the other end is inserted while holding the base part by hand, and the installation worker applied a voltage to the straight tube fluorescent lamp type LED illuminator. The base part is held with the hand in the state, and depending on how it is held, the attachment work is performed with the hand or part of the body in contact with the power connection terminal of the base part.

  In conventional straight tube fluorescent lamps, filaments are connected to the power connection terminals at both ends in the fluorescent lamp tube. When the lamp is lit, the voltage is applied to the filament from the lamp fixture via the power connection terminals at the caps at both ends of the fluorescent lamp tube. Is applied to the fluorescent material in the fluorescent tube to emit light, which is emitted from the electrons emitted from the filaments at both ends and the mixed gas sealed. For this reason, there is no circuit board in which the power supply circuit and the light source are arranged in the fluorescent tube, and the power supply connection terminals at both ends of the straight tube fluorescent lamp are not electrically connected. Therefore, as described above, the replacement work is performed while holding the base part by hand, and even if the hand of the replacement operator or a part of the body contacts the power connection terminal of the base part, A voltage is applied to the filament connected to the power connection terminal of the straight tube fluorescent lamp inserted into the terminal hole of one insertion socket from the lamp fixture, but the other hand or part of the body is No voltage is applied to the filament connected to the contacted power connection terminal.

  However, the straight tube fluorescent lamp type LED illuminator accommodates an LED circuit board in which the power conversion unit and the LED elements of the light source are arranged in the inside thereof, and the power connection unit including the power connection terminal from the lamp fixture and the power conversion unit. Since the LED element is lit by supplying power to the LED circuit board, the power connection terminals at both ends are electrically connected via the power conversion unit of the straight tube fluorescent lamp type LED illuminator. Yes. The power connection part has a base part, and when the hand holding the base part is also in contact with the power connection terminal as described above, the other body part of the worker is connected to earth ground. If it comes into contact with another connected conductive object or earth ground, the straight fluorescent lamp LED at one end inserted from the lighting fixture into the insertion socket from the power supply of the lighting fixture supplied with commercial power The power supply connection terminal arranged in the base part of the illuminator, and the power supply connection terminal applied to the power supply connection terminal arranged in the base part at the other end from the power supply connection terminal at one end through the power conversion part in the LED tube Electricity is also transmitted to the worker who is in contact with the terminal. This forms a path through which current flows from the other human body part of the worker to the ground via another conductive object, and as a result, electricity flows through the human body of the worker and is electrocuted.

  Therefore, for example, when a single power switch is used to operate a plurality of lighting devices arranged on the ceiling, it is desirable not to turn off lighting devices that do not require work. When performing an installation operation of a tube fluorescent lamp type LED illuminator, a structure in which the installation operator does not receive an electric shock is required.

It is characterized by having a safety switch means for turning off the energization without being pressed.
