Description

  Embodiments of the present invention relate to a lighting device to which a straight tube lamp including a cover that houses a light emitting element used as an emergency light source is mounted.

  Conventionally, for example, an emergency lighting fixture that uses a straight tube lamp as a light source that is lit in an emergency has a structure in which when a straight tube lamp is a fluorescent lamp, the phosphor emits light by discharge inside the cover. Is made of glass and can be easily replaced by the user when replacing the lamp or battery.

  In recent years, straight tube lamps using light emitting elements such as LEDs as a light source have become widespread. In the case of such a straight tube lamp, since discharge and gas sealing in the cover are unnecessary, the cover is not limited to glass but may be made of resin.

  However, in the case of an emergency lighting fixture, it is necessary to use a straight tube lamp provided with a glass cover in order to ensure durability against external fire. In such a case, it is desired not to attach a straight tube lamp using a resin cover as a light source that is accidentally turned on in an emergency.

The covering member main body 51 is held in a cylindrical shape so as to be along the outer peripheral surfaces of the caps 17a and 17b of the straight tube lamp 11.

  For example, the sheet 56 is formed in a quadrangular shape using, for example, an elastic synthetic resin, and is attached to the inner surface of the covering member main body 51 of the covering member 33 on both sides of the opening 51a. Therefore, a part of the outer periphery of the caps 17a and 17b is elastically held by these sheets 56.

  Next, the operation of the lamp system 10 will be described.

  The installation of the straight tube lamp 11 will be described. First, in the straight tube lamp 11, the caps 17a and 17b at both ends are respectively inserted into the covering members 33a and 33b holding the sheet 56 therein, and these caps 17a and 17b are inserted. The lamp pin 25 and the lamp pin 26 protruding from the socket 32a and 32b are inserted from the slits 46 and 46, respectively, and the lamp pins 25 and 25 are fitted into the grooves 42a and 42a of the rotor 42, so that the straight tube lamp 11 is inserted into the socket 32a. , 32b. Next, the straight tube lamp 11 is rotated by 90 °, and the straight tube lamp 11 is mounted at predetermined mounting positions of the sockets 32a and 32b.

  Further, the covering members 33a and 33b located at both ends of the straight tube lamp 11 are tightened in a state where the facing portion 52 is positioned so as to face both sides or the lower side of the socket bodies 41 and 41 of the sockets 32a and 32b. The screw 55 inserted from below into the insertion hole 53a of the insertion portion 53 is inserted into the tightening hole 54a of the tightening portion 54, and the screw 55 is tightened with a tool so that the tightening portions 53 and 54 are tightened together. The covering members 33a and 33b are fixed in a state where the caps 17a and 17b of the straight tube lamp 11 are sandwiched.

  In this state, the sheet 56 is pressed against the outer peripheral surfaces of the caps 17a and 17b, and the covering members 33a and 33b are configured so that the covering member body 51 covers the caps 17a and 17b, and the facing portion 52 is the socket body of the sockets 32a and 32b, respectively. The straight tube lamp 11 in which the caps 17a and 17b are connected and fixed to the sockets 32a and 32b can be rotated by the covering members 33a and 33b. The straight tube lamp 11 cannot be removed from the sockets 32a and 32b.

  Therefore, according to the present embodiment, the covering member that covers the caps 17a and 17b of the straight tube lamp 11 and is fixed to the straight tube lamp 11 at a position where the portion faces the side portion 58 of the sockets 32a and 32b. 33 is provided, the rotation of the straight tube lamp 11 with respect to the sockets 32a and 32b (the rotation of the straight tube lamp 11 in the removing direction) abuts the covering member 33 and the side portion 58 of the sockets 32a and 32b. Therefore, unless the cover member 33a, 33b covering the caps 17a, 17b of the straight tube lamp 11 is shifted or removed by loosening the screw 55 with a tool, the straight tube lamp 11 is removed from the sockets 32a, 32b. Therefore, the straight tube lamp 11 including the semiconductor light emitting element 21 used as an emergency light source can be prevented from being undesirably removed from the sockets 32a and 32b.

  For this reason, it is possible to prevent the user from easily replacing the straight tube lamp 11 having the glass translucent cover 15 with a straight tube lamp using a resin cover. It is possible to provide the lamp system 10 that ensures durability against fire and the like.

  Moreover, since the covering member 33 has a simple structure with a cylindrical shape with a C-shaped cross section that is simply tightened with the screws 55 at the tightening portions 53 and 54, the cost of parts can be reduced, and the tool body 31 can be reduced. Therefore, even when the conventional straight tube lamp is replaced with the straight tube lamp 11 using the LED, the change of components can be minimized.

  In particular, the emergency lighting straight tube lamp 11 using the long-life semiconductor light-emitting element 21 is not frequently replaced. Therefore, the sockets 32a and 32b of the straight tube lamp 11 are covered by the covering members 33a and 33b. Even if easy removal from the illuminating device main body 12) is hindered, there is no inconvenience in substantial use.

  Further, since the covering members 33a and 33b cover the positions of the caps 17a and 17b in the vicinity of the sockets 32a and 32b in a direction intersecting with the longitudinal direction of the straight tube lamp 11, the translucent cover 15 is covered. The light of the semiconductor light emitting element 21 that is transmitted and irradiated is not blocked by the covering members 33 and 33, and darkening of the appearance during light emission is suppressed.

  Furthermore, since the covering members 33a and 33b are formed of a flame retardant member such as metal, the durability of the caps 17a and 17b against fire and the like can be further improved.

  In addition, since the sheet 56 that is pressed against the caps 17a and 17b of the straight tube lamp 11 and increases friction against the caps 17a and 17b is attached to the covering member 33 in a state where the covering member 33 is fixed, On the other hand, the covering member 33 can be fixed more firmly, and when the straight tube lamp 11 is rotated, it is more difficult to rotate around the covering member 33, and the stress of fixing the straight tube lamp 11 by the covering member 33 ( Stress).

  Further, the tightening portions 53 and 54 of the covering member 33 are arranged on the opposite side to the emission direction (horizontal direction) intersecting (orthogonal) the light emission direction (vertical direction) from the straight tube lamp 11 ( Therefore, it is difficult to see the tightening portions 53 and 54 and the screws 55 for tightening the tightening portions 53 and 54 from the light emitting direction, and it is possible to suppress a decrease in appearance. In addition, with the covering member 33 fixed to the straight tube lamp 11, the positions of the tightening portions 53 and 54 are in the range of 0 ° to 60 ° upward with respect to the horizontal direction. 54 does not come too close to the installation surface or wall, or the instrument body 31, etc., and the tightening portions 53, 54 project from the instrument body 31 to the side and do not interfere with the installation. Workability can be secured. In the lamp system 10, when two or more straight tube lamps 11 are provided substantially parallel to each other, the tightening portions 53 and 54 of the covering member 33 are opposed to each other in each straight tube lamp 11. If it is positioned at the position, the light of the semiconductor light emitting element 21 that is irradiated through the translucent cover 15 is not blocked, and darkening of the appearance during light emission is suppressed. Moreover, the fall of appearance can be suppressed. Furthermore, the workability of tightening the screw 55 can be secured.

  Then, the pair of covering members 33a and 33b fixed to the caps 17a and 17b of the straight tube lamp 11 are arranged on a predetermined surface where the positions of the tightening portions 53 and 54 are along the light emission direction from the straight tube lamp 11. For example, when the lamp system 10 is installed on the upper part of the wall surface, the fastening portions 53 and 54 of the covering members 33a and 33b are respectively connected to the ceiling side, for example. By being configured so as to be positioned at, the tightening portions 53 and 54 and the screw 55 for tightening the tightening portions 53 and 54 can be made more difficult to see.

  In the above-described embodiment, the sheet 56 is not an essential component as long as the covering member 33 can be securely fixed to the straight tube lamp 11.

  Further, the facing portion 52 is provided so as to be continuous over both sides of the socket body 41 of the sockets 32a and 32b, but each of the two directions of the rotation direction of the straight tube lamp 11 (forward rotation direction and reverse rotation direction). If it is provided so as to face the sockets 32a and 32b at the position, it is possible to prevent undesired removal due to the rotation of the straight tube lamp 11.

  Further, the straight tube lamp 11 may not be always lit as long as the semiconductor light emitting element 21 is used at least for emergency.

  The covering member 33 is integrally formed, and the fastening portions 53 and 54 are fastened to each other by a screw 55 and fixed to the straight tube lamp 11. For example, the covering member 33 is divided into a plurality of parts, and these parts are formed. It is good also as a structure which provides a fastening part in each, and fixes with a screw, and is good also as a structure fixed with the fastening member etc. which consist of a volt | bolt and a nut.

  Furthermore, when a socket with a waterproof cap is used around the caps 17a and 17b of the straight tube lamp 11, a covering member 33 is provided so as to cover the periphery of the waterproof cap of the socket with the waterproof cap. Since a part of the member 33 is fixed to the straight tube lamp 11 at a position facing the side of the socket, the straight tube lamp 11 is rotated with respect to the socket (the straight tube lamp 11 is rotated in the removing direction). Motion) is regulated by abutment between the covering member 33 and the side of the socket, so that the screw 55 is loosened with a tool to cover or remove the covering members 33a, 33b covering the caps 17a, 17b of the straight tube lamp 11 Otherwise, the straight tube lamp 11 cannot be rotated with respect to the socket, so that the straight tube lamp 11 including the semiconductor light emitting element 21 used as an emergency light source is not undesirably removed from the socket. It can be.
