Description

  The present invention relates to an adapter, and more particularly to an adapter for mounting an LED fluorescent lamp on a lamp.

  In recent years, fluorescent lamp type lamps using LEDs (hereinafter referred to as “LED fluorescent lamps”) have been used as lighting fixtures to replace existing fluorescent lamps (hereinafter referred to as “conventional fluorescent lamps”). Compared with fluorescent lamps, it has a longer life and consumes less power, and can emit various colors.Generally, conventional fluorescent lamps and LED fluorescent lamps have the same shape.

  By the way, the conventional fluorescent lamp and LED fluorescent lamp which have a straight pipe shape are provided with two terminals at each end. FIG. 7 is a view showing a state in which the conventional fluorescent lamp 1 is mounted on the lamp 2 for the conventional fluorescent lamp 1. The two terminals 3 provided at one end of the conventional fluorescent lamp 1 are connected to the filament 4 inside the conventional fluorescent lamp 1. Similarly, the two terminals 3 provided at the other end of the conventional fluorescent lamp 1 are connected to the conventional fluorescent lamp 1. Connected to the filament 4 inside the lamp 1. In addition, by attaching the conventional fluorescent lamp 1 to the lamp 2, the power supply circuit 5 inside the lamp 2 is connected to one terminal 3 at one end and one terminal 3 at the other end of the conventional fluorescent lamp 1, and A circuit 6 having a glow lamp for raising the voltage at the time of starting the conventional fluorescent lamp 1 is connected to the remaining terminals 3. The filament 4 inside the conventional fluorescent lamp 1 has no directionality, and the two filaments 4 connected to the terminals 3 at both ends of the conventional fluorescent lamp 1 are the same as each other. The direction to connect to is not limited.

  On the other hand, in the case of an LED fluorescent lamp, since it is not necessary to connect a glow lamp, two of the four terminals at both ends are not used. An LED fluorescent lamp is one in which the internal circuit of the LED fluorescent lamp is connected to two terminals at one end and the internal circuit of the LED fluorescent lamp is not connected to two terminals at the other end (hereinafter, the background art and the invention are to be solved). The internal circuit of the LED fluorescent lamp is connected to one terminal at one end and one terminal at the other end, and the internal circuit of the LED fluorescent lamp is connected to the remaining terminals at both ends. Some are not connected (hereinafter referred to as “second LED fluorescent lamp” in the background art and problems to be solved by the invention). Since the lamp for mounting the first LED fluorescent lamp supplies power only to one end of the first LED fluorescent lamp, the power circuit inside the lamp is only at one of the two protrusions for mounting both ends of the first LED fluorescent lamp. Connected. Further, in the lamp for mounting the second LED fluorescent lamp, the positive electrode of the power circuit inside the lamp is connected to one of the two protrusions for mounting both ends of the second LED fluorescent lamp, and the other is the lamp internal The negative electrode of the power supply circuit is connected. Thus, since the LED fluorescent lamp and the lamp for the LED fluorescent lamp have directionality, the LED fluorescent lamp must be mounted in the correct direction with respect to the lamp for the LED fluorescent lamp.

  The conventional fluorescent lamp, the first LED fluorescent lamp, and the second LED fluorescent lamp have the same shape, and it is difficult to distinguish the conventional fluorescent lamp, the first LED fluorescent lamp, and the second LED fluorescent lamp from the appearance alone. Further, the lamp for the conventional fluorescent lamp, the lamp for the first LED fluorescent lamp, and the lamp for the second LED fluorescent lamp have the same shape, and the lamp for the conventional fluorescent lamp and the lamp for the first LED fluorescent lamp have the same shape. It is difficult to determine the lamp for the second LED fluorescent lamp. Therefore, there is a possibility that the conventional fluorescent lamp, the first LED fluorescent lamp, and the second LED fluorescent lamp are mistaken. Similarly, there is a risk that the conventional fluorescent lamp, the first LED fluorescent lamp, and the second LED fluorescent lamp will be mistaken. Due to the problems described above, the following inconvenience occurs when each fluorescent lamp is mounted on the wrong lamp.

  When the first LED fluorescent lamp is mistakenly mounted on a conventional fluorescent lamp, voltage is not applied to the internal circuit of the first LED fluorescent lamp, and the first LED fluorescent lamp does not emit light. If the second LED fluorescent lamp is mistakenly attached to a conventional lamp for a fluorescent lamp, a reverse voltage may be applied to the internal circuit of the second LED fluorescent lamp, and the internal circuit of the second LED fluorescent lamp may be damaged.

  If the conventional fluorescent lamp is mistakenly attached to the lamp for the first LED fluorescent lamp, a voltage may be applied to one filament inside the conventional fluorescent lamp and the filament may be damaged. When the second LED fluorescent lamp is mistakenly attached to the lamp for the first LED fluorescent lamp, no voltage is applied to the internal circuit of the second LED fluorescent lamp, and the second LED fluorescent lamp does not emit light.

  When the conventional fluorescent lamp is mistakenly attached to the lamp for the second LED fluorescent lamp, no voltage is applied to the filament inside the conventional fluorescent lamp, and the conventional fluorescent lamp does not emit light. When the first LED fluorescent lamp is mistakenly attached to the lamp for the second LED fluorescent lamp, no voltage is applied to the internal circuit of the first LED fluorescent lamp, and the first LED fluorescent lamp does not emit light.

  Patent Document 1 discloses an adapter for facilitating attachment of a conventional fluorescent lamp when the conventional fluorescent lamp is attached to a lamp.

Japanese Patent Laid-Open No. 2001-143837

  However, the adapter disclosed in Patent Document 1 is intended to facilitate the attachment of the fluorescent lamp to the lamp, and not only the conventional fluorescent lamp and the lamp for the conventional fluorescent lamp, but also the first LED fluorescent lamp and the first LED. It can also be attached to a lamp for a fluorescent lamp or a lamp for a second LED fluorescent lamp and a second LED fluorescent lamp. Therefore, even if such an adapter is attached to a fluorescent lamp and a lamp, the fluorescent lamp and the lamp to which the adapter is attached are the conventional fluorescent lamp and the conventional fluorescent lamp, or the first LED fluorescent lamp and the first LED fluorescent lamp. I do not know whether it is a lamp for the second LED fluorescent lamp or the second LED fluorescent lamp. That is, such an adapter cannot solve the above-mentioned problem.

  The main object of the present invention is to provide a first LED fluorescent lamp (an LED fluorescent lamp in which the internal circuit of the LED fluorescent lamp is connected to the two terminals at one end and the internal circuit of the LED fluorescent lamp is not connected to the two terminals at the other end). 1LED fluorescent lamp (a lamp for mounting an LED fluorescent lamp in which the internal circuit of the LED fluorescent lamp is connected to the two terminals at one end and the internal circuit of the LED fluorescent lamp is not connected to the two terminals at the other end) It is to provide an adapter that can be correctly attached.

  To achieve the above object, the adapter according to claim 1 is provided with two terminals at one end and the other end thereof, an internal circuit is connected to the two terminals at one end, and the two terminals at the other end. Is an adapter attached to an LED fluorescent lamp to which no internal circuit is connected, and a lamp including a first protrusion on one end and a second protrusion on the other end for mounting the LED fluorescent lamp, A first member that is attached to the other end of the fluorescent lamp; and a second member that is attached to the second protrusion of the lamp and holds the first member when the LED fluorescent lamp is mounted on the lamp. When the LED fluorescent lamp to which the member is attached is mounted on the lamp to which the second member is attached, the portion that contacts the LED fluorescent lamp in the first member and the portion that contacts the lamp in the second member are insulated. It is characterized by.

  The adapter according to claim 2 is the adapter according to claim 1, wherein the second member includes a recess, and the first member is held by fitting the first member into the recess.

  In the adapter according to claim 1, the first member is an LED fluorescent lamp in which the internal circuit of the LED fluorescent lamp is connected to the two terminals at one end and the internal circuit of the LED fluorescent lamp is not connected to the two terminals at the other end. Hereinafter, it is attached to the other end of the “first LED fluorescent lamp” in means for solving the problem. The second member is attached to the second projecting portion of the lamp for mounting the first LED fluorescent lamp. From the appearance, it can be seen that the fluorescent lamp to which the first member is attached and the lamp to which the second member is attached are lamps for the first LED fluorescent lamp and the first LED fluorescent lamp. It can be seen that the other end of the first LED fluorescent lamp to which the first member is attached corresponds to the second protruding part to which the second member is attached in the lamp for the first LED fluorescent lamp. It can be seen that the one end to which the second member is not attached corresponds to the first protruding portion to which the second member is not attached in the lamp for the first LED fluorescent lamp. Therefore, one end of the first LED fluorescent lamp is connected to the first protrusion of the lamp for the first LED fluorescent lamp via, for example, a socket, and the other end of the first LED fluorescent lamp is the second of the lamp for the first LED fluorescent lamp. It connects to a protrusion part via the 1st member and the 2nd member. Therefore, the first LED fluorescent lamp can be correctly attached to the lamp for the first LED fluorescent lamp by using such an adapter.

  The other end of the first LED fluorescent lamp to which the first member is attached is electrically insulated from the second protrusion of the lamp for the first LED fluorescent lamp to which the second member is attached. Therefore, for example, even if the second protrusion of the lamp for the first LED fluorescent lamp is charged, no voltage is applied to the other end of the first LED fluorescent lamp. There is no. Therefore, such an adapter can improve safety when the first LED fluorescent lamp is attached to and detached from the lamp for the first LED fluorescent lamp.

  In the adapter according to claim 2, the second member holds the first member by fitting the first member and the concave portion of the second member. When the concave portion of the first member and the second member are fitted and the first LED fluorescent lamp is mounted on the lamp for the first LED fluorescent lamp, the terminal is inserted into the socket of the lamp for the first LED fluorescent lamp, and the first LED fluorescent lamp is inserted. The contact area of the connection portion between the first LED fluorescent lamp and the lamp for the first LED fluorescent lamp is larger than that when the lamp is mounted on the lamp. Therefore, it is possible to prevent the first LED fluorescent lamp from falling by attaching such an adapter.

  According to the present invention, an LED fluorescent lamp in which the internal circuit of the LED fluorescent lamp is connected to the two terminals at one end and the internal circuit of the LED fluorescent lamp is not connected to the two terminals at the other end is mounted on the LED fluorescent lamp. An adapter that can be correctly attached to the lamp is obtained.
