DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a lighting fixture of a type that is waterproof and is attached to a ceiling lower surface or a wall surface.

[Prior Art] FIG. 4 shows a conventional luminaire of this kind, in which a base 41 is formed in a cylindrical shape whose one surface is closed, and the closed surface side serves as a mounting surface to a ceiling lower surface or a wall surface. Base 4
A perforated globe 42 is attached to the first opening surface. The lamp 43 is arranged at the center of the base 41, so that the socket mounting base 45 for mounting the socket 44 is arranged at the upper side in the drawing. Also, the base 4
A terminal block 46 for connecting an electric wire from the outside is arranged on the right side of 1, and a glow socket 48 for mounting a glow ball 47 and a ground terminal 49 are also arranged. Further, a ballast 50 composed of a transformer or the like is arranged on the left side of the base 41.

[Problems to be Solved by the Invention] In the conventional example, since the lamp 43 is turned on by the wire-wound ballast 50, since the ballast 50 is short, the ballast 50 appears as a shadow on the globe 42. It never happened. However, when the lamp 43 is lit at a high frequency by an electronic circuit, there is a problem that the shape of the lighting device is relatively bulky and the shadow of the lighting device appears on the globe.

The present invention has been provided in view of the above-mentioned points, and it is possible to uniformly lighten the gloves and, when mounting on a wall, simply attach the gloves in accordance with a general wiring work method, and the irradiation efficiency in the downward direction is reduced. It is an object of the present invention to provide a lighting fixture which has a heightened height and facilitates the drop of water drops when dew condensation occurs.

[Means for Solving the Problems] In order to achieve the above-mentioned object, the present invention provides a lamp arranged in the center of a base, a lighting device arranged on the side of the lamp for lighting the lamp, and a lamp. And a lighting fixture having a globe that covers the lighting device and is attached to the base, the end of the light emitting portion of the cantilever type lamp to be mounted is attached to the base near one end on the center line that divides the base into left and right. The socket is tilted so that the position of the end of the light emitting portion becomes higher than the height of the lighting device that is arranged in parallel with the lamp, and the base near the other end on the center line is placed. A terminal block for connecting the power supply line is provided, and the longitudinal direction of the printed circuit board of the lighting device is parallel to the center line.

[Operation] However, by arranging the end portion of the light emitting portion of the lamp so as to project toward the globe side with respect to the lighting device and be inclined, the shadow of the lighting device is not reflected on the globe, and the globe is uniformly brightened. It is possible to improve the downward irradiation efficiency by only mounting the base so that the terminal block is on the top and the socket block is on the lower side when it is mounted on the upper wall surface, and it faces diagonally downward of the lamp, Moreover, in this case, the longitudinal direction of the printed circuit board of the lighting device is the vertical direction, so that it becomes easy to drop the water droplets attached to the printed circuit board due to dew condensation downward.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings. First
The figure shows the entire luminaire, which can be installed either horizontally on the underside of the ceiling or vertically on the wall. The base 1 is formed in a cylindrical shape in which the mounting surface side is closed and the front surface side is open. A ring-shaped fixture 2 is arranged on the opening side of the base 1, and the fixture 2
A threaded portion 3 is formed at the intermediate portion of the above, and the end portion of the fixture 2 is formed as a flange 4 projecting inward of the base 1 in a ring shape. A cylindrical portion 6 having a smaller diameter is formed in the rear portion of the translucent globe 5 attached to the opening surface of the base 1, and the outer peripheral surface of the cylindrical portion 6 is screwed with the screw portion 3 on the base 1 side. The screw part 7 to be fitted is threaded. In addition, glove 5

The mounting base 9 includes a mounting piece 10 arranged parallel to the bottom surface of the base 1, a vertical piece 11 arranged perpendicularly to the bottom surface of the base 1, and a cover piece arranged parallel to the bottom surface of the base 1. It is composed of 12 and. Mounting base 9
The mounting piece 10 is formed in a substantially U shape, and one side thereof is provided with a ground terminal mounting portion 14 for mounting the ground terminal 13 and a terminal block mounting portion 16 for mounting the terminal block 15. On the other side of the mounting piece 10, a socket mounting portion 19 for arranging the socket mounting base 18 is formed. The socket 17 is mounted on the socket mounting base 18, and the lamp 20
Are attached to the socket 17. As shown in FIG. 3, the socket mounting portion 19 is formed by obliquely cutting and raising the socket 17, and the socket 17 is disposed obliquely so that the tip side of the light emitting portion of the lamp 20 is a lighting device, that is, the cover piece 12.
It is made to project toward the globe 5 side. Therefore, a space is generated between the terminal block 15 and the tip of the lamp 20, the space for connecting the power line to the terminal block 15 is increased, and the power line is less likely to contact the lamp 20.

As described above, the grounding terminal 1 is attached to the mounting piece 10 of the mounting base 9.
Since parts such as 3, the terminal block 15, and the socket mount 18 are integrally mounted, the assembling property can be improved. Further, in FIG. 1, the socket mounting portion 19 is arranged near the lower end on the center line that divides the base 1 into the left and right, and the terminal block 15 is arranged near the upper end of the center line.
When the terminal block 15 is arranged on the upper side as shown in the figure and the cantilever type lamp 20 is attached to the socket 17, the lamp 20 is arranged at the center of the base 1 and the light emitting surface of the lamp 20 is inclined downward. Become. As shown in FIGS. 1 and 2, the mounting pieces 10 are mounted with screws 21 in parallel with the bottom surface of the base 1 at a predetermined interval, and the mounting base 9 is mounted on the base 1.

A lighting device 22 for lighting the lamp 20 is composed of a high-frequency lighting device such as an inverter, and electronic components forming the lighting device 22 are mounted on a printed board 23. The printed board 23 is attached in parallel to the vertical pieces 11 of the mounting base 9 via a mounting tool 24 at regular intervals, and the surface of the printed board 23 is perpendicular to the bottom surface of the base 1. Has become. By arranging the printed board 23 in this way, the back surface of the printed board 23 becomes vertical to the ceiling surface when the lighting equipment is arranged on the lower surface of the ceiling, and the printing is performed even when the lighting equipment is arranged on the wall surface. The longitudinal direction of the plate 23 is arranged in the up-down direction, and the surface of the printed board 23 is in the vertical direction, so that even if dew condensation occurs on the printed board 23, moisture does not collect on the back surface of the printed board 23.

The cover piece 12 of the mounting base 9 is formed in a substantially semicircular shape in accordance with the shape of the base 1, and the lighting device 22 is attached to the printed board 2.
It covers 3 and insulates. Further, as shown in FIG. 2, an L-shaped piece 25 is integrally formed on the bottom surface side of the base 1 along the circumference at the tip of the cover piece 12,
Of the L-shaped piece 25 is in contact with the upper surface of the flange 4 of the fixture 2, that is, the tip of the L-shaped piece 25 and the flange 4 are overlapped with each other. Keeps it out of direct water.
The lighting apparatus of the present invention constructed as described above can be mounted not only on the ceiling surface but also on the wall surface, and particularly when mounted on the wall surface, the following features can be exhibited. That is, when mounting the base 1 on a wall surface, this type of lighting fixture is mounted on a switch box provided on the wall surface side, and thus corresponds to a switch box normally arranged on the base 1 in the vertical direction. Mounting screw insertion holes with a predetermined pitch are provided on the upper and lower sides, and an electric wire insertion hole is provided near the center of the base 1. Therefore, at the time of installation, water drops are transmitted along the electric wire and the terminal block 15
