Abstract

The utility model discloses an elevator suspended ceiling, in particular to an ultrathin suspended ceiling for elevator cars, comprising a frame, a light guiding plate and a strip light source; the light guiding plate and the strip light source are arranged on the frame and the fame is fixed on the top of the elevator car; the strip light source is positioned at the edge of one side or more than one side of the light guiding plate; the backside of the light guiding plate is light transmission microstructure in the shape of micro-particle or/and strip and/or cellular, and can diffuse soft ray or partial reflecting and refractive ray. The utility model has the advantages of excellent illuminating effect and space saving of the elevator car.

Description

The ultra-thin furred ceiling of lift car

Technical field

The utility model relates to a kind of elevator furred ceiling, the ultra-thin furred ceiling of especially a kind of lift car.

Background technology

The elevator furred ceiling is not only the main decoration parts of lift car, or the installation place of lighting source, general car furred ceiling all is the top that is suspended on lift car at present, owing to loaded onto illuminations such as bulb, lampshade annex, the thickness of car furred ceiling is generally all between 15 centimetres to 20 centimetres, and the furred ceiling of the more complicated that has even more than 30 centimetres has occupied bigger car height space.

Under the certain situation of car height, the space that furred ceiling occupies is big more, and the actual available space of car is more little, also causes sense of depression with regard to easy more to the passenger, if but the thickness of attenuate furred ceiling can make the decoration result of furred ceiling have a greatly reduced quality again.Particularly when furred ceiling adopts large tracts of land evenly to throw light on, generally all require furred ceiling thicker.Therefore not only if want to have preferably the car spatial impression but also think that furred ceiling is designed beautifully, just need to adopt high car design, and the design of high car has proposed requirement to the hoistway headroom height, to having relatively high expectations of civil engineering, has greatly improved construction cost.

As Chinese patent application 03801498.X disclosed " lighting system of elevator ", its a plurality of cold-cathode fluorescence lamps with arrangement in parallel are installed on the reflecting plate, and the light that cold-cathode fluorescence lamp sends comes out by baffle reflection.A plurality of cold-cathode fluorescent lantern festivals take bigger space, therefore use the furred ceiling of this Lighting System to have the shortcoming that volume is big, thickness is thicker.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of good illumination effect, saves the ultra-thin furred ceiling of lift car in car space.

The technical scheme in the invention for solving the above technical problem is: the ultra-thin furred ceiling of this lift car is made of frame, LGP and strip source, and LGP and strip source are contained on the frame, and frame is fixed on the sedan-chair top; Strip source is positioned at a wherein side or the above edge of a side around the LGP; The LGP back side is the printing opacity microstructure of minitype particle and/or strip and/or trellis, and it can scatter soft light or partial reflection, refracted ray.

Frame described in the utility model is made by opaque metal, plastics or wooden material, and its shape and elevator sedan-chair top are complementary; Described LGP is made by glass material or transparent polymer material; Described strip source can be at least a in LED, daylight lamp, gas luminescence fluorescent tube or the halogen lamp tube; The microstructure at the described LGP back side is handled by screen printing, laser ablation, high temperature sintering, mechanical engraving, sandblast or chemical corrosion mode and is formed.

The utility model compared with prior art has following beneficial effect: this furred ceiling is processed into the LGP back side can scattered beam or the printing opacity microstructure of partial reflection, refracted ray; The strip source that is installed in the LGP side is launched light, after light is coupled into LGP from the side of LGP, owing to having taken place, total internal reflection hangs down the damage transmission, optical energy loss is very little, but when light runs into the LGP back side through screen printing, laser ablation, high temperature sintering, mechanical engraving, after sandblast or chemical corrosion mode are handled the microstructure that forms, because microstructure can scattered beam or partial reflection, refracted ray, and ratio of refraction is also different, so destroyed the total internal reflection of light, therefore last light will be from the microstructure outgoing, reach light from the positive outgoing effect of LGP, play illumination purposes.Simultaneously, because the arranged direction of last exit direction of light and strip source is vertical, so that the volume of furred ceiling can be done is very thin very little, reach below 2 centimetres, and can realize large-area even illumination, the actual illumination area can be greater than 1 sq m, and outward appearance fashion is beautiful.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is a use reference diagram of the present utility model.

The specific embodiment

Referring to Fig. 1, Fig. 2, present embodiment comprises LGP 1, strip source 2 and furred ceiling frame 3, LGP 1 is made by glass material, the printing opacity microstructure of fine particle shape is processed at the back side of LGP 1 through screen printing, this microstructure can scatter soft light or partial reflection, refracted ray, strip source 2 is that furred ceiling frame 3 is made by opaque metallic material by the LED light-emitting section of LED grain composition; LGP 1 is fixedly mounted in the furred ceiling frame 3, furred ceiling frame 3 is fixed by bolts on the sedan-chair top 4, furred ceiling frame 3 can also play the parasitic light effect that stops that strip source 2 is sent except that the effect of playing lightguide plate fixing, strip source 2 is installed in the edge of side all around of LGP 1.Strip source 2 needed power supplys 5 are installed in the top on sedan-chair top 4.

During use, be installed in that furred ceiling presents in flakes luminous zone uniformly on the sedan-chair top 4, strip source 3 sends be optically coupled into LGP 1 after, owing to having taken place, total internal reflection hangs down the damage transmission, optical energy loss is very little, but run into the microstructure at LGP 1 back side when light after, because microstructure can scattered beam or partial reflection, refracted ray, and ratio of refraction is also different, so destroyed the total internal reflection of light, therefore last light will reach light from LGP 1 positive outgoing effect from the microstructure outgoing.

Strip source 2 in this illumination equipment also can be in daylight lamp, gas luminescence fluorescent tube, the halogen lamp tube one or more combination, and strip source 2 also can be installed in the edge of one or two or three sides around the LGP 1.The microstructure at LGP 1 back side also can be handled by laser ablation, high temperature sintering, mechanical engraving, sandblast or chemical corrosion and form, and this microstructure can be wire, strip, graininess or combination in any wherein.Furred ceiling frame 3 also can be made by materials such as plastic opaque, timber.For improving illuminating effect, also can add the reflecting horizon that one deck increases emergent ray efficient at the back side of LGP 1.
