Abstract

The utility model discloses a luminous element for improving the luminous efficiency and simplifying the assembly procedure through providing high brightness and distribution uniformity in the working area, which comprises a body which inner surface represents sphere arch, a plurality of luminous diode moulds which are arranged on the body and are assembled in groups as symmetrical distribution corresponding to the center hoop on the inner surface of the body. In one group, the luminous diode moulds lie at different distances from the body center. The luminous diode moulds in all groups are arranged according to the same pattern. The scale of the sphere radius for forming the inner surface of the body is ranged from 0.8 to 1.2 m. the luminous element also comprises a decoration surface and a transparent cover, for example, which is made of optical polycarbonate and has the same shape as the inner surface of the body. The inner surface of the body and the cover can be realized by the pattern of sphere cross section component.

Description

Illuminating equipment

Technical field

The present invention relates to field of medical technology, relate in particular to operating lamp.

Background technology

Existing illuminating equipment comprises that (referring to Russian utility model number is RU27852 for the body, transparent cover plate and the light diffusing board that have with the luminescence unit of matrix dot matrix LEDs plate form, international Patent classificating number IPC is F21V11/00, and open day is the patent documentation on February 20th, 2003).

This existing illuminating equipment assembles very compactly, and this is because described illuminating equipment needs a large amount of light emitting diodes (LED), to be issued to required illumination level in the not high enough situation of luminous efficiency.

Existing no shadow cold light illumination equipment comprises a ring and a power supply that has with the light-emitting component of a plurality of light emitting module forms, wherein each light emitting module is fixed on that (referring to russian patent No. is RU2252441 on the rod that is installed in the spherical seam crossing recess on the described ring, international Patent classificating number IPC is G02B21/06, and open day is the patent documentation on May 20th, 2005).

The shortcoming of this existing apparatus is the position that needs to adjust each led module.

Technical is operating lamp near the application, comprise the body of forming by the standalone module of a plurality of mutual mechanical couplings, wherein led module is fixed on the inner surface of described body and (referring to European application number is: EP1568935, international Patent classificating number IPC is F21S8/00, F21S2/00, and open day is the patent documentation on August 31st, 2005).

This existing operating lamp has the high characteristics of illumination efficiency, but the structure of this operating lamp is quite complicated.

Summary of the invention

Technical problem solved by the invention is a structure of simplifying illuminating equipment, keeps its higher luminous efficiency simultaneously, and above-mentioned purpose realizes by following proposal.

According to claimed invention; the operation illuminating equipment comprises that inner surface is fixed with the body of a plurality of led modules; the body of described illuminating equipment is made into one; its inner surface is made into lune of a sphere; this led module is divided at least 4 groups and is symmetrically distributed with hoop with respect to the body center on the inner surface of this body, and the arrangement of led module is identical in each group.

In every group, led module is different to the distance at body center.

In addition, form the radius of a ball scope of body internal surface from 0.8 meter to 1.2 meters.

In addition, illuminating equipment is provided with the cover plate identical with the shape of illuminating equipment body, is for example made by the light Merlon.

In claimed illuminating equipment, body is made into one, and inner surface is made into lune of a sphere, and this has simplified the structure of illuminating equipment.Led module is divided at least 4 groups, is configured on the inner surface of this body with respect to the body center and hoop ground is symmetrically distributed, and the interior location of led module is identical in each group, and this has also simplified the structure of illuminating equipment, and the even illumination of assurance surgery location.When the led module on the illuminating equipment body internal surface is divided into three groups or group still less,, can not when operation, provide enough illuminations because shadow is arranged.The inner surface of illuminating equipment body is made the luminous flux that lune of a sphere can make single led module send combine in groups, thereby optimize luminous flux.

In each group, led module is different to the distance at body center, and each group is distributed on the Internal Spherical Surface of body, because the combination of the luminous flux of all groups can guarantee that the light distribution height of inside, workspace is even.

By experiment, the scope of the radius of a ball of determining this illuminating equipment body internal surface is from 0.8 meter to 1.2 meters, and this luminous flux combination to led module is optimum, and described module by combination also guarantees the luminous flux optimum of surgery location.When the radius of a ball less than 0.8 meter or during greater than 1.2 meters, all can reduce the size of workspace, reduce the illumination efficiency of illuminating equipment.

For example the cover plate of being made by the light Merlon has the shape identical with the inner surface of illuminating equipment body, and characteristics are the propagation coefficient height to visible light, improves illumination efficiency, gets rid of the accumulation of dust on the light source.

The combination of above-mentioned illuminating equipment feature of asking for protection can be simplified the structure of illuminating equipment, keeps higher illumination efficiency simultaneously.

Description of drawings

Fig. 1 is total figure of illuminating equipment;

Fig. 2 is mounted in a plurality of led modules of the inner surface of illuminating equipment body;

Fig. 3 is the schematic diagram that the luminous flux of a plurality of led modules is formed.

The specific embodiment

Illuminating equipment comprises body 1, bottom cover plate 2 and a plurality of led module 3.The body of illuminating equipment has extraneous adornment surface 4 and inner surface 5, and wherein the group 6 of led module 3 formation is attached on the inner surface 5.The quantity of the group 6 that led module 3 forms is according to concrete needs, can from 4 to 8.

In workspace 7, to combine from the luminous flux of led module 3, this workspace 7 is 0.7 meter to 1.4 meters to the distance of body 1, this is an optimal value for surgical lighting device.

At the illuminating equipment duration of work, illuminance is the highest is that consequent luminous flux is the combination of the luminous flux of the group 6 in the workspace 7 in the inside, workspace of each group 6 that is formed by led module 3.Keep almost constant light field diameter in each group workspace of 6, this is very important concerning surgical lighting device, belongs to the luminous flux that the led module 3 of different group 6 sends and combines, and makes that the light distribution height of 7 inside is even in the workspace.

The present invention can be used for medical skill.
