Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a compact and portable fluorescent lamp fixture.

[Conventional technology]

Portable fluorescent light fixtures using small fluorescent lamps use a built-in power supply to oscillate a transistor inverter to light the fluorescent lamp at high frequency, but little consideration has been given to the reflector installed behind the fluorescent lamp. Instead, a flat reflector was simply placed to hide the inside of the device, or a concave reflector was provided along the fluorescent lamp. Fluorescent lamps are essentially diffuse light sources, and even if a concave reflector is installed as described above, it will not be possible to obtain the sufficient light-concentrating effect as when using a light bulb as a light source. Portable fluorescent light fixtures are lighting fixtures that use a diffused light source with a larger luminous flux than portable light bulbs, and are suitable for illuminating a wide area.

[Problem that the invention seeks to solve]

The above conventional technology uses a concave reflector that focuses the luminous flux of the fluorescent lamp forward, so the irradiation direction of the portable fluorescent lamp is limited to a specific direction, and the fluorescent lamp is a diffused light source. However, consideration has not been given to expanding the irradiation range over a wide range by taking advantage of the present invention.The object of the present invention is to obtain a portable fluorescent lamp fixture that is compact and capable of illuminating a wide range.

[Means for solving problems]

The above object is achieved by forming a reflection plate installed behind the fluorescent lamp in a convex shape along the fluorescent lamp.

[Effect]

By installing a convex reflecting plate along the fluorescent lamp behind the fluorescent lamp, the luminous flux emitted toward the rear of the fluorescent lamp is reflected by the reflecting plate, and the luminous flux of the fluorescent lamp, which is a diffused light source, is The illumination is more diffuse and can illuminate a wider area. Furthermore, by utilizing the space formed on the back side of the convex reflecting plate and arranging the components, it is possible to make the portable fluorescent lamp fixture more compact.

It is divided into two pieces for ease of assembly, and in this embodiment, pieces of exactly the same shape are used facing each other in order to manufacture them at low cost. FIG. 2 is a diagram showing the structure of the main body, in which all the parts for lighting the fluorescent lamp 2 are attached to the main body 3 on one side, covered with the main body 4 on the other side, and then assembled by screwing. 6 is an inverter, 7 is a transformer, 8 is a battery, 9 is an 0N-OFF switch, 10 is a voltage selection switch, 11 is a detachable cord with a plug, 12 is an outlet to which the cord with a plug is detachably attached, 13 is the above-mentioned transparent This is a set screw for fixing the optical cover 1 to the main body 3.4.

In the portable fluorescent lamp device of the present invention, the shape of the reflector 1 is formed in a convex shape along the fluorescent lamp 2 in order to make the irradiation range as wide as possible and to make the shape of the device as small as possible. .

The shape of the convex portion of the reflecting plate 5 is such that, as shown in the cross section in FIG. However, if the reflective surface 5 is formed so as not to block the direct light beam of the fluorescent lamp 2, as shown in FIG. 4, the same height α as shown in FIG. 3 can be achieved. Even with the held reflecting plate 5, it is possible to expand the irradiation range to the full extent of the open area formed by the reflective slope.

In order to store the inverter 6, which is a lighting component, in the main body, the fifth
It is better to mount the device diagonally using the space formed by the back surface of the convex reflector 5 as shown in FIG. The overall height can be lowered, and the translucent cover 1
The position of the mounting screw 13 for mounting the lamp is also secured sufficiently, and it becomes possible to make the portable fluorescent lamp fixture more compact.

In this embodiment, two bodies 3.4 of the same shape made of synthetic resin etc. are used to reduce assembly man-hours with the aim of achieving low cost.
A locking protrusion and a screw seat for attaching the parts are preformed on each of them.

That is, as shown in FIG. 7(a), the upper edge of the inverter 6 is locked to the locking protrusion 14 protruding inside the main body 3, and the hole 16 on the lower edge is screwed into the screw seat 18 of the main body 3. stop it,
As shown in FIG. 7(b), the transformer 7 has its lower end connected to the main body 3.
The upper end hole 17 is fixed to the locking protrusion 15 and screwed to the screw seat 19, and is attached by two or one screw, respectively. As a result, the number of man-hours required for screwing can be reduced to 172, which is the usual number.

Also, a battery 8, each switch 9 and 10. The outlets 12 are fitted into the respective gaps in the corresponding notches 1, socket contact pieces (not shown) are inserted and wired, and then
As shown in FIG. 8, the assembly of the main body is completed by stacking another main body 4 on the main body 3 to which the above-mentioned parts are attached and fastening them with screws, and then attaching the transparent cover 1 with screws 13.

The handle 20 of the portable fluorescent lamp shown in FIG. 9 is made of an elastic material such as steel wire, and is attached so as to sandwich the main body of the above embodiment from both ends by utilizing the elasticity of the handle 20.
It can be fixed in any way. In addition to being used as a handheld device as shown in FIG. 10, it can be used in a variety of ways, such as by hanging it on a wall as shown in FIG. 11 or as a stationary device as shown in FIG. 12. Furthermore, if an adjustable string made of vinyl or the like is attached in place of the handle 20, it can be worn over the shoulder as shown in FIG. 13, which is convenient because both hands can be used freely.
