Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an embedded work lighting device for lower maintenance work of an automobile or the like.

[0002]

[Prior Art]

 In the past, when servicing the lower parts including the wheels and brake system during vehicle inspections, the necessary maintenance work was performed from under the vehicle body after the vehicle body was lifted to a predetermined height by a lift or the like.

It is necessary to ensure a predetermined brightness for maintenance work. Normally, the lighting in the work place is fully considered from above, but the lighting from below is not enough and the lighting from below is not enough. Various luminaires for underpass work have been developed and used for work.

However, these illuminating devices for under-work are semi-portable ones that can move on the floor due to the nature of the work, and not only require a cord, but also the floor and the object to be maintained. Since it needs to be placed in a narrow space, it not only interferes with maintenance work, but also the size of the equipment is limited, so that a large-sized luminaire that can secure sufficient brightness cannot be used, and therefore, it cannot be used locally. The one with a brightness of about 300 lux was moved and used according to the work position.

[0005]

[Problems to be solved by the device]

 The present invention has been made in view of the above circumstances, and provides an embedded work lighting device in which the brightness of a wide area can be sufficiently secured without hindering the work by embedding the fixture in the floor. It is an object.

[0006]

[Means for Solving the Problems] An embedded work lighting device according to the present invention is a housing arranged below the floor surface, an illuminating lamp provided inside the housing, and a translucent and waterproof structure. It is characterized in that it comprises a tempered glass for sealing the upper part of the housing through a packing member for use, and a thin plate-like shock absorbing member which is transparent and elastic and is provided so as to cover the upper surface of the tempered glass. Another feature is that a light scattering member for scattering illumination light is provided between the illumination lamp and the tempered glass.

[0007]

[Action]

 With this configuration, it is possible to illuminate from the floor surface to the top without occupying the work space.

[0008]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1A is a plan view of this embodiment, and FIG. 1B is a side sectional view of the same. In these figures, reference numeral 1 designates a casing, which is dug down so that the upper side surface 1a thereof is substantially the same as the surface of the floor 2 and is arranged therein. A fluorescent lamp 3 is fixed to the housing 1 via a socket 3 a in the housing 1. The lower surface of the housing 1 also serves as a reflector for the light of the fluorescent lamp.

A transparent tempered glass 4 having a strength of about 2600 kg (at 50 mmΦ) is fitted to the upper side surface 1 a of the housing 1 through a waterproof packing 5, and the weight of the vehicle passing through the floor 2 In addition to withstanding the water, it prevents water and the like flowing on the floor 2 from entering the housing 1.

Further, a transparent vinyl sheet 6 having a thickness of about 1 mm is adhered to the upper surface of the tempered glass 4 to soften the impact when, for example, a tool is dropped on the tempered glass 4. Prevents the tempered glass 4 from being damaged.

The thickness including the tempered glass 4 and the vinyl sheet 5 is formed to be substantially the same as that of the upper side surface 1a, and is designed so as not to obstruct the passage of a vehicle or the like.

Further, a diamond cut glass 7 is provided between the fluorescent lamp 3 and the tempered glass 4 in the housing 1, and scatters the light of the fluorescent lamp 3 to allow the illumination light to travel in one direction. To prevent people from gathering.

With such a configuration, the illumination light of the fluorescent lamp 3 illuminates a wide range from the floor 2 surface to the upper direction through the diamond-cut glass 7, the tempered glass 4 and the vinyl sheet 6, and is about 600 lux. The brightness of can be secured. Moreover, since the lighting equipment is installed under the two floors, it does not interfere with the work. The present invention is not limited to the above embodiment, and can be modified and implemented within the scope not changing the gist.

Although the fluorescent lamp is fixed to the housing in the above-mentioned embodiment, the brightness in the necessary direction can be adjusted according to the work by changing the settings of the fluorescent lamp and the reflector. Can also be adjusted.

If a removable internal housing is provided inside the housing and a fluorescent lamp is attached to this internal housing, installation of the housing on the floor and wiring of the fluorescent lamp are performed. Each can be done independently. Furthermore, it is possible to easily replace the fluorescent lamp.

[0017]

[Effect of the device]

 According to this invention, since the luminaire is arranged below the floor surface, it does not hinder the work, and since a large illuminating lamp can be used without occupying the work space, the work range can be widened. In addition, it is possible to illuminate brightly and improve work efficiency.
