Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to bedlight for use in hospital rooms.

[Background technology]

Conventionally, in this type of beddurite for hospital rooms,
Since the reflector was fixed and the light distribution characteristics were fixed, when the patient used it, it could cause glare to the patient on the bed facing him, or conversely, the light source ( The drawback was that books could become difficult to read because the fluorescent lamps came into direct contact with the eyes.

[Purpose of the invention]

The present invention has been made in view of the above points, and it is an object of the present invention to provide a bed light for a hospital room that can arbitrarily change the front and rear light distribution characteristics and has a simple configuration.

[Disclosure of invention]

(Embodiment) FIGS. 1 to 4 show an embodiment of the present invention, in which 1 is a straight tube type fluorescent lamp disposed horizontally within an instrument main body 2, and the instrument main body 2 is a main body housing 3. , a transparent cover 4 , a fluorescent light socket 5 , a ballast (not shown), and a blinking switch 6 . This instrument body 2 has a hinge portion 7a at one end.
The base end of the arm 8 is attached to the side end of a storage box 9 buried in the bedside wall W of the bed B by a hinge 7b. Therefore, the device main body 2 can be freely adjusted in position near the bedside of the bed B, and can be stored in the storage box 9. Reference numeral 10 denotes a reflective sheet having an inverted U-shaped cross section that covers the upper part, front and rear of the fluorescent lamp 1, and is made of a flexible film, and the reflective surface is mirror-finished or white. The light distribution adjustment means 11 that adjusts the light distribution by sliding the reflective sheet 10 includes guide pulleys 14 arranged on both ends of the straight tube fluorescent lamp 1 horizontally arranged in the instrument main body 2, and the guide pulleys 14 14
The guide plate 13 is arranged so as to wrap around the guide plate 13 to form an inverted U-shaped gap between the guide pulley 14 and the guide plate 13, and both edges of the reflective sheet 3 formed of a flexible film are The reflective sheet 10 is slidably inserted into the gap, and the slide knobs 12 protruding from the outer surfaces of both end edges of the reflective sheet 10 are made to protrude through guide grooves 15 bored in the instrument body 2, and both slide knobs 12 are operated. By doing so, by sliding the reflective sheet 10 along the gap, the lengths of the front and rear portions of the reflective sheet 10 that cover the upper and front and rear parts of the straight tube fluorescent lamp 1 can be adjusted reciprocally. There is. In the figure, 16 is a socket base to which the straight tube type fluorescent lamp 1 is connected.

Now, slide knob 12 of light distribution adjustment means 11
When you slide it in the direction of arrow A, the reflective sheet 1
0 is slid to the rear side, and as shown in Figure 5a, the length _l1 of the rear part becomes longer and the length _l2 of the front part becomes shorter, so that the light distribution characteristics become brighter in the front and The patient in bed B' will be shielded from light. On the other hand, when the slide knob 12 is slid in the direction of arrow B, the reflective sheet 10
is slid forward, and as shown in Figure 5b, the length _l1 of the rear part becomes shorter and the length _l2 of the front part becomes shorter, so direct light that enters your eyes is blocked. It can make books easier to read.
As described above, in the embodiment, the light distribution adjusting means 1
By operating the slide knob 12 of 1, the reflective sheet 10 can be slid to arbitrarily change the front and rear light distribution characteristics, making it possible to easily obtain the optimal light distribution characteristics according to the situation. It's becoming like that. Furthermore, since the light distribution characteristics are achieved by a simple mechanism of sliding the reflective sheet 10, the configuration is simple and the cost is low.

[Effects of the invention] As described above, the present invention has guide pulleys placed on both ends of a straight fluorescent lamp that is horizontally arranged within the device body, and a guide plate that is placed so as to wrap around the guide pulleys. Then, an inverted U-shaped gap is formed between the guide pulley and the guide plate, and both ends of a reflective sheet made of a flexible film are slidably inserted into the gap, and both ends of the reflective sheet are inserted into the gap. Slide knobs protruding from the outer surface of each edge are made to protrude through guide grooves drilled in the instrument body, and by operating both slide knobs, the reflective sheet is slid along the gap, and the straight pipe is removed. The lengths of the front and rear parts of the reflective sheet that covers the upper and front and rear parts of the straight fluorescent lamp are adjusted reciprocally, and the lengths of the reflective sheet are adjusted reciprocally. Both edges of a reflective sheet made of a flexible film are slidably inserted into the inverted U-shaped gap formed by the guide plate, and projecting protrusions are provided on the outer surface of both edges of the reflective sheet. Since the slide knobs protrude through guide grooves drilled into the main body of the instrument, the reflective sheet made of flexible film can be smoothly slid by operating both slide knobs. This has the effect of simplifying the configuration without requiring a means to impart lateral rigidity to the flexible film.Also, since the reflective sheet is formed from a flexible film, the reflective sheet can be hung down. It is possible to obtain an arbitrary light shielding effect and also to effectively utilize the light reflected by the hanging portion.
