Abstract
The invention relates to an illuminating device with higher light scattering, which comprises a side-opening box-shaped body (12). The box-shaped body (12) is internally provided with at least one light source (14), the side-opening of the box-shaped body is provided with a diffusing screen (16) which is fixed on a supporting structure (20) that can be connected with the box-shaped body (12) so as to cause the peripheral part of the supporting structure (20) to be basically superposed with the surrounding walls of the box-shaped body (12).
Description
Technical field
The present invention relates to a kind of lighting device with high light scatterring.
Background technology
As everyone knows, the large-scale lighting device that uses separately or be used in combination to constitute actual illumination wall has a shortcoming, produces disagreeable shadow region, particularly at its periphery edge that is:.
When in the same side more ceiling light being arranged, above-mentioned influence is especially obvious, because in fact can form the shade grid on the illumination wall, this has reduced the efficient of whole illuminator, and causes the aesthetic effect that makes us unhappy.
Large-scale lighting device is provided with a scattering wall of being made by nonrigid material usually, for example transparent or semitransparent cloth sheet, it need have the peripheral frame of exposure on the framework of device, this framework has dual-use function, promptly support the scattering wall and guarantee that the scattering wall is attached and stably be fixed on the device framework that illumination component is installed, and above-mentioned defective normally causes therefrom.
Therefore, peripheral frame defines shelter wall for the light of scattering mural margin, thus and formation shadow region.
At present another shortcoming of the large-scale lighting device on market is, owing to be impossible from installing self front near electronic component, therefore breaking down and/or one or more illumination component need change the time, has caused difficulty to the technical staff.
Summary of the invention
Therefore, the purpose of this invention is to provide a kind of lighting device, it can guarantee best light scattering, reduces the phenomenon that forms the shadow region along the periphery of device self as far as possible.
Another object of the present invention provides a kind of lighting device with high light scatterring, and it allows easier near lamp and internal electronic element.
Further object of the present invention provides a kind of lighting device with high light scatterring, and it is simple and practical especially, and has lower cost.
For reaching above-mentioned purpose of the present invention, provide a kind of as the lighting device described in the claim 1 with high light scatterring.
Further feature of the present invention is emphasized by dependent claims.
Description of drawings
In the mode of example the feature and advantage of the lighting device with high light scatterring among the present invention are described in further detail below with reference to accompanying drawing, wherein:
Accompanying drawing 1 is the perspective view according to the embodiment of lighting device provided by the invention, the lighting device that particularly has open configuration;
Accompanying drawing 2 is fragmentary, perspective views of the lighting device shown in the accompanying drawing 1;
Accompanying drawing 3 is outer peripheral partial sectional views of the lighting device shown in the accompanying drawing 1;
Preferred implementation
Special in appended accompanying drawing 1, for having the lighting device of high light scatterring, entirety by reference numeral 10 represents that it comprises: the box-shaped body 12 that a side is uncovered, body interior accommodate at least one light source 14 shown in the figure; Can cover the scattering wall of box-shaped body 12 front surfaces fully or shield 16.
Except power line and being used for the electric/electronic device of control device 10, box-shaped body 12 also comprises the lamp socket 18 (seeing accompanying drawing 3) of light source 14, shown in specific example embodiment in, light source 14 is made up of the more neon lamp that is arranged on box-shaped body 12 inside.
Box-shaped body 12 can be made by different materials, as metal or plastics, and can be used to single and/or a plurality of equipment that are installed on the ceiling or hang by the tie-rod (not shown).
In described example, diffuser screen 16 is made of translucent material piece, and this material piece is fixed on by known attachment arrangement on the supporting construction or peripheral frame 20 on the box-shaped body 12 that is fit to attach to lighting device.
Advantageously, for minimizing meeting as far as possible produces blocking of shadow region along lighting device 10 periphery edges, still keep the rigidity of large-scale plant structure simultaneously, framework 20 is configured to adhere to the sidewall of box-shaped body 12, perhaps also can select to cover fully sidewall.
In other words, the peripheral part of framework 20 overlaps substantially with the perisporium of box-shaped body 12, does not therefore need to be used to support the support frame of diffuser screen 16 certainly on one's body in box-shaped body 12.
In addition, diffuser screen 16 can be configured to after diffuser screen 16 has been mounted to framework 20 self to small part cover framework 20, constituting independent scattering surface, this surface coverage the front portion of box-shaped body 12 of lighting device 10, and outside being exposed to without any profile.
Shown in accompanying drawing 2 and accompanying drawing 3, the framework 20 that supports diffuser screen 16 is equipped with the system that is used to be attached on the box-shaped body 12, and this system is made of a plurality of elastic devices 22, for example metal spring.
Clearer and more definite, each spring 22 forms one by suitable groove 24 and framework 20, one or more attachment part 26 is equipped with and, this attachment part engages with the appropriate section (not shown) of box-shaped body 12 so that removably connect the box-shaped body 12 of framework 20 and lighting device 10, thereby and connects the diffuser screen 16 be fixed on the framework 20 and the box-shaped body 12 of lighting device 10.
By this method, can be in the simple and rapid mode directly from the front of lighting device near the lamp 14 and the electric component of lighting device 10, and do not need to utilize special tool(s).
Can see, the purpose that lighting device with high light scatterring according to the present invention has been emphasized before having reached, because guarantee from the front near lamp in, the present invention is also because to support the thickness of peripheral frame of diffuser screen very little and the formation of shade is reduced to minimum.
And, possibility with the complete cover framework of scattering wall self makes it possible to obtain the wall that throws light on uniformly, and can not cause because of the profile that exposes interrupting, the lamp of inside that can be by adopting different colours is also made the illumination wall in conjunction with more lighting device, so just discontinuous influence is reduced to minimum.
Therefore the lighting device that the present invention has high light scatterring can under any circumstance carry out multiple improvement and variation, and all improvement are all covered by identical innovation concept with changing.Therefore, for example light source can be made up of fluorescent lamp, LED or other lighting devices, yet diffuser screen can for example be made of transparent or semitransparent POLYCARBONATE SHEET, rather than is made of aforesaid cloth sheet.
At last, in fact employed material and size thereof and component can be according to any kind of technical need.
