Description

  The present invention is to attach a functional circuit device other than lighting to a straight tube LED lamp that can be lit by being mounted on a socket of an existing fluorescent lamp fixture and has end parts each having a pin terminal at both ends. , Connection structure for enabling connection with pin terminals so that it can be handled as if it were a single straight tube type LED lamp, that is, a cartridge type having a pin terminal mounting hole on one side and a pin terminal on the other side The present invention relates to a safe connection mechanism with a housing.

Conventionally, it is a casing having a cross-sectional shape substantially the same as a straight tube fluorescent lamp having a pin terminal and a pin mounting hole, and this is connected to a pin terminal on one side of the straight tube fluorescent lamp, and this connection body is connected to an existing tube There was an idea of a fluorescent lamp-related product that was installed in a socket of a fluorescent lamp fixture and had a function other than lighting by a device built in the casing. Specifically, the housing with a built-in wireless transceiver connected to the pin terminal and the pin terminal mounting hole is mounted in the socket of an existing fluorescent lamp fixture so that the external shape is adjusted so that it can be seen integrally with the straight tube fluorescent lamp Wireless transmitter / receiver (Patent Document 1) that performs wireless transmission / reception operation and maintains good illumination even when the fluorescent lamp is turned on, and a negative ion generator with a negative ion generator function built into the housing A known fluorescent lamp (Patent Document 2) is known.
JP 1996-237763 JP2008-66267

  The idea of the former (Patent Document 1) is to perform wireless LAN relay by a device built in a housing connected to a straight tube fluorescent lamp that is widely used as a lighting fixture. The connection mechanism is a plug-in type using a simple pin terminal and a pin terminal mounting hole.

  The idea of the latter (Patent Document 2) is to perform the negative ion generator by a device built in a casing connected to a straight tube fluorescent lamp. The connection mechanism has a simple structure in which an end part having terminal pins of a fluorescent lamp slightly enters the terminal pin socket of the housing.

  These ideas were useful without the need for new wiring because conventional fluorescent lamp fixtures were used, but there was a weak point in the connection mechanism using pin terminals and pin terminal mounting holes common to these ideas. . Even though there are some differences, both are basically held by inserting the pin terminal and the pin terminal mounting hole, but these ideas, which can only be called simple connection methods, There was a risk that the fluorescent lamp and the housing could fall together due to poor contact or damage of the pin terminals at the connection between the fluorescent lamp and the case due to vibration, shock, repeated external force, or incorrect operation during attachment / detachment.

  As mentioned in the prior art, the idea of using a straight tube fluorescent lamp and adding a new functional circuit device as if it were a single fluorescent lamp was useful without requiring new wiring. However, this idea also had a technical error of weak connection strength. Originally, the pin terminal connection is for locking only a light fluorescent lamp to the socket of a fluorescent lamp fixture. When a housing connected by an idea like a conventional technology, that is, a pin connection is attached to a fluorescent lamp, it is connected. There was a risk of falling together with the fluorescent lamp when the part was subjected to vibration, impact, or repeated external force.

  Today, LED lighting with a long life and low power consumption is becoming mainstream due to the demands of the times and society, but the cost of dedicated equipment and the cost of electrical work have become a major burden. For this purpose, various types of straight tube LED lamps having the pin terminals that can be used for existing fluorescent lamp fixtures or special fixtures have been commercialized. These are built-in DC power sources and are of the existing ballast connection system, and there are three types: magnetic starter type, rapid starter type, and inverter type. In any case, they are heavier than hollow fluorescent lamps, at least 50% more than conventional fluorescent lamps.

  In the present invention, the type of the functional circuit device mounted on the cartridge type housing is not specified. However, if the mounted functional circuit device is exemplified, a fragrance generator, a negative ion generator having an air cleaning function, a CCD Examples include an imaging device, a fire alarm device, an emergency light automatic lighting device and a power storage device in the event of a power failure, and a radio wave repeater.

  It is desirable that the cartridge-type housing for mounting them be modularized in volume and length. However, the internal structure and appearance according to various functional circuit devices may be changed within a range that does not destroy the outer shape of the basic cartridge type casing. In this case, the total length of connecting the cartridge type housing and the straight tube type LED lamp must be a length that can be used with an existing fluorescent lamp apparatus or a dedicated apparatus.

  In order to realize this, in the case of the structure in which the cartridge type housing is simply connected with pin terminals as in the idea described above, the connection portion is repeatedly damaged by external force, and the straight tube type LED lamp is returned. There is concern that the risk of falling will be greater than before. In order to obtain a product that can meet such needs, the present invention provides a mechanism that can safely connect and exchange the function of the cartridge type housing on which the functional circuit device other than various illuminations is mounted to the straight tube type LED lamp. There is to get.

And is adjusted in length so that it can be installed in a socket of an existing fluorescent lamp device or a dedicated device. In the case where this connection body is directly attached to the socket of the corresponding existing fluorescent lamp apparatus or dedicated apparatus, the connection section of the connection body may be caused by earthquake vibration or impact, or repeated external force or incorrect operation during attachment / detachment. In order to prevent this, there is a risk that the pin-type LED lamp and the cartridge-type housing will fall together.
