Description

The present invention relates to a stand-type LED lighting fixture.

Various self-standing stand-type lighting fixtures have been developed for lighting fixtures that are placed on a table or furniture, lighting fixtures that are placed on the floor indoors, and lighting fixtures that are installed outdoors.
With the spread of LED lighting in recent years, such lighting fixtures that have long-term durability and are smaller than conventional light bulbs and have various uses and designs have been developed.

For example, as a stand-type lighting fixture, one that stands on its own by a pole that stands upright from the pedestal and one that irradiates a place slightly away from the pedestal by a bent arm are known.
Further, those having a foldable arm whose height can be adjusted, a movable arm, an illusionary arm, and the like are known. According to such a lighting fixture, the height and the horizontal position of the light source unit can be adjusted by appropriately adjusting the movable arm.

By the way, in a room such as a living room or a commercial facility such as a restaurant or a store, not only the functionality of illuminating the hand or the product shelf, but also the design with excellent appearance and elegance is required.
From a functional point of view, in a stand-type luminaire that simply stands upright, the stand must be placed near the hand to be illuminated brightly. For this reason, it is necessary to leave a space for placing the stand at a close distance, and the pedestal part of the stand and the pole of the stand standing upright from the pedestal portion are obstructive and obtrusive.

Take, for example, lighting on open terrace seats in hotels and restaurants.
In such an environment, the current table lights mainly use lighting that illuminates from a low position such as a lantern or a candle lamp. Small ones are often used to keep them out of the way on the table.
However, no matter how small it is, the lights are often placed near the center of the table to illuminate brightly, which is an obstacle to taking up space.
Also, if the illuminance is not enough with a small table light, the color of the dish cannot be seen well. On the other hand, when a table light with strong illuminance is used, the light comes directly into the eyes and becomes dazzling.
Alternatively, even if it is an exhibit such as a flower arrangement, an exhibit at a commercial facility, a cultural facility, or a lighting fixture for decorating a product, there is no dedicated lighting suitable for making the exhibit shine. Indoors and at night, the lighting is insufficient and it is not attractive.

To avoid these problems, when using large floor-mounted lighting fixtures or lighting installed on the ceiling or walls of a store, the light source is located far away, creating shadows of people. If your hands get dark or if you use a table light with strong illuminance, the light will come directly into your eyes and it will be dazzling.
There is also a method of irradiating from a distant place using a strong light source such as a spotlight, but it is still dazzling because the light directly enters the eyes.
In addition, if it is a stand-type lighting fixture that has a foldable or movable arm, and even an arm that can be transformed, the stand can be placed at a distance from the hand that is the object to be illuminated brightly. There is a limit to the distance.
This is because if the horizontal distance from the pedestal part of the stand to the light source part at the tip of the arm is long, the head part with the light source and the weight of the arm itself cannot be withstood, and the lighting equipment becomes unstable and easily falls over. ..

Although there is a method of attaching a clamp to the pedestal part of a stand-type luminaire and fixing it to a table or the like, it becomes unstable if the weight of the head part or arm of the luminaire is supported only by the clamp. The force is concentrated on the table part where the clamp is attached, and if the clamp is loosened, it will be easily scratched, and if the clamp is removed, it will easily fall over.
Therefore, even if a clamp is attached to the pedestal portion of a stand-type luminaire and fixed to a table or the like, it is preferable not to rely only on the clamp but to use it only as an auxiliary for fixing the position.

For this reason, even for a lighting fixture that illuminates a place slightly away from the pedestal with a bent arm, the horizontal distance from the pedestal portion of the stand to the light source portion at the tip of the arm is at most the height of the lighting fixture in the past. The limit was about 1/4, or about 1/3 no matter how devised the design.
From the aspect of functionality, even if the lighting equipment illuminates a place slightly away from the pedestal with a bent arm, the brightness is sufficient if it is placed so far from the hand to be illuminated brightly. However, the stand must be placed relatively close to the person, as shadows may form behind the person.

In general, the ratio of "length of arc portion (21) / total length of arm portion (20)" is the length of arc portion (21) for larger size lighting fixtures in the shape shown in each figure. It tends to be easy to increase the ratio of "sa", but this is not always the case depending on the weight of the material.

In addition, it can be applied from small tabletops to large size ones, and the pedestal and stand arm interfere with various stand-type lighting fixtures such as tabletop stands, floor-standing indoor stands, and outdoor stands. It is possible to adopt a form in which it is difficult for people to cast shadows.

Next, the stand-type LED lighting fixture of the present invention supports the arm portion (20) to be connected and also includes a pedestal portion (30) containing a power supply unit (31).
Although it depends on the weight of each part of the luminaire and the center of gravity, a weight can be built in the pedestal portion (30) at the bottom thereof or the like, if necessary.
