Description

A kind of ultra-wide extrusion LED lamp affixed to the ceiling PMMA lampshade

Technical field

This utility model relates to a kind of ultra-wide extrusion LED lamp affixed to the ceiling PMMA lampshade.

Background technology

Lamp affixed to the ceiling, in business, office lighting and lighting of home, is widely used, particularly LED lamp affixed to the ceiling, is being widely used the most especially, and the feature such as its power saving, brightness height, life-span length is approved by masses；LED lamp affixed to the ceiling ingredient is by chassis, power drives, LED light source, PMMA lampshade and plug end cap；Traditional lamp affixed to the ceiling, refer generally to circle or square ceiling lamp, along with developing rapidly of LED illumination industry, gradually bigger toward light-emitting area, more powerful direction is developed, lamp affixed to the ceiling overall dimensions aspect is also in change, LEDPMMA lamp shade of ceiling lamp on existing market, with expressing technique one-shot forming out, width dimensions is generally less than 300mm, and width is all completed by secondary operations plastic uptake or bending technique with PMMA sheet material more than 300mm's, and operation is the most, middle waste is the biggest, and cost can be the highest.

Utility model content

The technical problems to be solved in the utility model is: overcome the deficiency in prior art, it is provided that a kind of operation is few, low cost, one-shot forming, middle waste is few, and its light transmittance controls relatively more flexible, is greatly saved the ultra-wide extrusion LED lamp affixed to the ceiling PMMA lampshade of the cost of manufacture.

This utility model solves its technical problem and be the technical scheme is that a kind of ultra-wide extrusion LED lamp affixed to the ceiling PMMA lampshade, there is lamp shade body, lamp shade body includes refractive elements and mounting part, the cross sectional shape of described refractive elements is the ellipse with opening, the opening part of refractive elements connects mounting part, lamp shade body uses printing opacity PMMA material to make, and its light transmittance is 85%, and the wall thickness of described lamp shade body is 2 ± 0.1mm.

Further, described refractive elements and mounting part are integrated extrusion molding structure, simple in construction, and easy to make, operation is few, and middle waste is few, low cost.

Further, described refractive elements not existing flex point curved surface, uniform illumination, light is soft, will not produce human eye and stimulate, and the luminous energy of light source is fully genuine simultaneously utilizes, and does not easily cause waste.

The beneficial effects of the utility model are: this utility model simple in construction, operation is few, low cost, one-shot forming, middle waste is few, its light transmittance controls relatively more flexible, is greatly saved the cost of manufacture, efficient, reliable, safe, durable, energy-conserving and environment-protective, anti-flammability is high, and impact resistance is strong, and light resistance is good.

Accompanying drawing explanation

With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.

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

1. lamp shade body in figure, 3. refractive elements, 4. mounting part.

Detailed description of the invention

Presently in connection with accompanying drawing, this utility model is further described.These accompanying drawings are the schematic diagram of simplification and basic structure of the present utility model are described the most in a schematic way, and therefore it only shows the composition relevant with this utility model.

nullA kind of ultra-wide extrusion LED lamp affixed to the ceiling PMMA lampshade as shown in Figure 1，There is lamp shade body 1，Lamp shade body 1 includes refractive elements 3 and mounting part 4，The cross sectional shape of described refractive elements 3 is the ellipse with opening，Lamp shade body 1 has the semiellipse shape convex lens shape of particular aspect ratio by giving photopermeability lampshade，And in lampshade, add light diffusing agent，Realize high brightness and uniform area source and the stability of optics，Light diffusing agent interpolation concentration and additive concentration make the loss reduction of transmitted light，And guarantee that LED linear light scatters，Linear light sorurce is done step-by-step face luminescence，Improve brightness，The opening part of refractive elements 3 connects mounting part 4，Mounting part 4 is mounted on lamp body，Thus when light fixture carries out regular maintenance or maintenance without whole lamp is removed and can safeguard or keep in repair，Conveniently process and save the time，It is substantially reduced maintenance or maintenance cost，Lamp shade body 1 uses light transmissive material to make，Its light transmittance is 85%，The wall thickness of described lamp shade body 1 is 2 ± 0.1mm.

Refractive elements 3 and mounting part 4 are integrated extrusion molding structure, flex point curved surface is there is not on refractive elements 3, not only achieve light fixture in the different optical effects of different angles and the utilization rate that improves light source, reach good energy-saving effect, there is superior photopermeability, light diffusing simultaneously, luminous uniform, atomized surface effect, anti-glare.

Concrete lamp shade body 1 uses PMMA material to make, and color is milky, and its light transmittance reaches more than 85%, uniform wall thickness, facet is smooth, and perpendicularity is good, the application passes through expressing technique, extrusion molding LED PMMA lampshade, its width can be more than 300mm, reach 370mm width, the light transmittance of the application controls more flexible simultaneously, realize the change of light transmittance height, and can cut according to demand, be greatly saved manufacturing cost.

Above-mentioned embodiment is only for illustrating technology of the present utility model design and feature; its object is to allow person skilled in the art will appreciate that content of the present utility model and to be carried out; protection domain of the present utility model can not be limited with this; all equivalence changes made according to this utility model spirit or modification, all should contain in protection domain of the present utility model.
