Drawings

Fig. 1 is a schematic structural view of the frosted operating lamp of the present invention.

Detailed Description

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

Referring to fig. 1, including lighting fixture 1, fixed locating lighting fixture 1 and being at least three light source 2 and the lamp shade 3 of locating lighting fixture 1 that slides that the circumference was arranged, 3 numbers of lamp shades are the same with 2 numbers of light source, and lamp shade 3 is greater than light source 2, and lighting fixture 1 is equipped with the slide rail 4 that supplementary lamp shade 3 moved to light source 2 department.

The lampshade 3 arranged on the lamp holder 1 in a sliding mode is arranged, the lampshade 3 can slide to the cover and is arranged on the light source 2, the lampshade 3 is far away from the light source when brighter light is needed, and the lampshade 3 can slide to cover the light source 2 when softer light is needed or fewer shadow areas are needed, so that the aim of softening the light is fulfilled.

The moving range of the lampshade 3 comprises a first limit position and a second limit position, the first limit position is that the lampshade 3 covers the light source 2, and the second limit position is positioned between the edge of the lamp holder 1 and the light source 2.

The first limit position is arranged, so that the lampshade 3 cannot exceed the position of the light source 2 due to excessive sliding, the possibility that light rays are still strong due to insufficient cage is reduced, and the danger caused by mutual collision of different lampshades 3 is also reduced.

The lamp shade 3 all is equipped with handle 31, and each lamp shade 3 all independently controls.

Set up handle 31, make the user need not direct touching lamp shade 3, lamp shade 3 covers for a long time and locates light source 2 and possibly have certain temperature, perhaps for the light shines the scope bigger occasionally, light source 2's higher difficult control in position sets up handle 31 and then can control lamp shade 3 very conveniently.

The lampshade 3 is made of frosted materials.

The frosted material can protect the light source 2 from accidental impact, disperse light and prevent the brightness of the light source 2 from being reduced.

The slide 4 connects the first extreme position and the second extreme position.

The lampshade 3 is arranged on the sliding rail 4 in a sliding mode, and the sliding rail 4 is provided with an intercepting block for limiting the lampshade 3 to exceed a first limit position or a second limit position.

The number of the slide rails 4 is the same as that of the light sources 2.

The slide rail 4 is two parallel rails, and the distance between the two rails forming the same rail is greater than the diameter of the light source 2.

The track interval is greater than the diameter of the light source 2, which is beneficial to reducing or eliminating the influence of the slide rail 4 on the light source 2 on the premise of ensuring that the lampshade 3 smoothly slides on the slide rail 4.

Shadowless frosted operating lamp principle:

If a cylindrical tea caddy is placed on a table and a candle is lighted beside the cylindrical tea caddy, a clear shadow can be cast on the cylindrical tea caddy. If two candles are lit next to a tea caddy, two overlapping, misaligned shadows will form. The overlapped part of the two images has no light ray and is completely black, so that the image is the shadow; the place beside the shadow where only one candle can shine is the half-bright and half-dark half-shadow. If three or even four candles are lighted, the shadow part will gradually shrink, and the penumbra part will have many layers. The reason is that the object can generate a shadow consisting of a main shadow and a penumbra under the light of the electric lamp. The lamp is illuminated by a bent filament, not limited to a point. Light from this one point is blocked from the object, and light from other points is not necessarily blocked. It is obvious that the larger the area of the light-emitting object, the smaller the self-shadow. If we point a circle of candle around the tea caddy, the shadow disappears completely, and the half shadow is light and invisible. Scientists have produced shadowless lamps for surgery based on the above principles. The lamp with high luminous intensity is arranged on the lamp panel to form a circle, so that a large-area light source is formed. Therefore, the light can be irradiated on the operating table from different angles, the enough brightness of the operation visual field is ensured, and meanwhile, an obvious ghost is not generated, so that the name of the shadowless lamp is got.

The specific embodiment is as follows:

When the lamp is placed at ordinary times, the lamp shade 3 is located at the second limit position.

When strong light is needed, the lampshade 3 is not moved and is directly used.

When needs are softer light, utilize handle 31 to drive lamp shade 3 along the motion of slide rail 4, from second extreme position motion to first extreme position, lamp shade 3 covers in light source 2 at first extreme position department cage, all carries out the scattering with light source 2's all light to make light soft, and because the light scattering, form multi-angle light, thereby reduced the appearance of penumbra and this shadow.

After use, the lampshade 3 is suggested to be brought to the second limit position by the handle 31, so that the light source 2 can dissipate heat conveniently.

The utility model discloses simple structure, convenient to use set up and slide and locate lamp shade 3 of lighting fixture 1 and make lamp shade 3 can slide and locate light source 2 to the cover, make light that needs are brighter make lamp shade 3 keep away from the light source, and need softer or need less shadow area the time then can slide lamp shade 3 and make lamp shade 3 cover locate light source 2 to reach the soft mesh of messenger's light.

However, the above description is only a preferred embodiment of the present invention, and the scope of the present invention should not be limited thereby, and all the simple equivalent changes and modifications described in the claims and the specification of the present invention are included in the scope of the present invention. In addition, the abstract and the title are provided for assisting the search of patent documents and are not intended to limit the scope of the present invention.
