Abstract
The utility model discloses a lamp shade of an LED (Light Emitting Diode) bulb, wherein the lamp shade is semitransparent and comprises a light extraction part relatively thicker at the bottom and a shade mouth mounting part gradually thinning at the edge; the lamp shade is formed by taking polycarbonate as base material and subjecting to processing modes such as injection molding, blow molding, molding, blow molding, extrusion, rolling, plating and coating and the like; the shape of the shade body at least comprises hemisphere, sphere cylinder, cylinder and prism; total or partial inner walls of lamp shades of various shapes are frosted surfaces or provided with light enhancing coatings; and annular clamping grooves or screw threads are arranged on the periphery of the lamp shade mouth so that the lamp shade can be connected with a light source cavity of a lamp shell. The lamp shade of the LED bulb has the advantages of breakage and dust prevention, ageing resistance, frosting effect, uniformity and softness in light extraction, no glare, high light extraction rate, simple processing mode, safety and reliability and can be widely used in the light distribution of various indoor illumination lamps and lanterns.
Description
Technical field
The utility model relates to a kind of lampshade, relates in particular to a kind of light fixture lampshade with led light source, belongs to technical field of semiconductor illumination.
Background technology
In current room lighting field, the fluorescent type electricity-saving lamp also is in the major product of traditional high efficiency light source competition at present, has the advantage that conventional light source is difficult to compare.But generally, it is a glass lamp shade, has frangible, difficult transportation and storage, can the release harmful substance endanger defectives such as environment.Also capture part market such as the low-power LED electricity-saving lamp in addition in addition, though the small-power luminous tube has the low advantage of luminescent device cost, people are in design during lampshade, go out light shield and be that transparent PC adds the frosted lampshade or the Ya Kelijia toner, and light transmittance is low; Led light source is a spot light, can see the internal point light source, shines inhomogeneous and possibly cause the user to dazzle light; Perhaps be exactly in lampshade, to adopt to apply or the frosted processing, with the diffuse reflection of formation light, but make that so again the light efficiency loss is very big, above scheme has all hindered effective application of light fixture more or less.
Summary of the invention
The utility model is in view of the defective of above-mentioned prior art scheme; The LED bulb lamp lampshade of a kind of high printing opacity, high diffusion, free from glare, no shadow is provided, uses high-quality light diffusion PC lampshade shock resistance, not broken, improve its light penetration rate; Reduce the brightness loss; Bright dipping is evenly spread, provide a kind of technology simply, production decision cheaply, promote the quick application implementation of new technology.
The purpose of the utility model will be achieved through following technical scheme:
A kind of LED bulb lamp lampshade; It is characterized in that: said lampshade is a base material with the Merlon of light transmittance more than 92%; Comprise relative thicker bright dipping part in top and the edge cover mouth mounting portion of attenuation gradually; Said lampshade global shape comprises hemispherical, goalpost shape, cylindrical, prismatic at least, and the lampshade inwall is matte surface or is provided with the coating of adding lustre to; Have on the said lampshade cover mouth excircle and be used for the annular snap access slot or the screw thread that are connected with the light-source chamber of lamp housing.
Further, the Merlon of said LED bulb lamp lampshade is a kind of in glass, resin or the PC polymeric material.
Further, said lampshade inwall is smooth sphere curved surface in the inner surface of bright dipping part, or be the sphere curved surface of frosted, again or be the sphere curved surface that is provided with the coating of adding lustre to.
Further, said lampshade cover mouth inwall is provided with the taperedchromeplatedbezel towards lampshade bright dipping part, annular.This taperedchromeplatedbezel metallizing reflecting layer; Or coating reflecting layer monochromatic or colored, fluorescent powder.And, this annular taperedchromeplatedbezel along the cover wall towards cover mouth gradually attenuation form a muscle rib.
This kind LED bulb lamp lampshade has clear superiority and beneficial effect:
Rational in infrastructure, the simplicity of design of the utility model has hear resistance, resistance to impact, high flame retardant, easy-formation; Effectively the light source disguise is splendid behind adjustment diffusivity and the light transmittance, high printing opacity, high diffusion, and light transmittance can make the light that led light source sent evenly spread 85～92%, free from glare, no shadow; It is luminous that realization changes into sphere with point light source light-emitting, obtained splendid illuminating effect, generally is suitable for the use of LED bulb lamp.
Description of drawings
Fig. 1 is the schematic perspective view of the utility model one embodiment;
Fig. 2 is a structural profile sketch map embodiment illustrated in fig. 1;
Wherein: mounting portion, the 3～taperedchromeplatedbezel of 1～bright dipping part, 2～cover mouth
The specific embodiment
A kind of LED bulb lamp lampshade as depicted in figs. 1 and 2, that the utility model provides, this lampshade shape that is translucent comprises that the top covers mouthful thicker bright dipping part 1 and the edge cover mouth mounting portion 2 of attenuation gradually relatively.This lampshade is that base material is processed with light transmittance at the Merlon more than 92%, a kind of in optional glass, resin or the PC polymeric material.
The cover body of this kind LED bulb lamp lampshade through injection moulding, blowing, moulding, blowing, extrude, roll, plate and technology mode such as be coated with and do to process, preferably adopt Shooting Technique.The cover body shape of processing comprises hemispherical, goalpost shape, cylindrical, prismatic at least, and the lampshade inwall of different shape is matte surface wholly or in part or is provided with the coating of adding lustre to.Have annular snap access slot or screw thread on the lampshade openend excircle, be used for being connected with the light-source chamber of lamp housing.
As the preferred implementation of the utility model, this lampshade inwall is smooth sphere curved surface in bright dipping part inner surface, or handles the diffuse reflection sphere curved surface that forms through frosted, or is provided with the coating of adding lustre to, and reduces light fixture dazzle sensation.Moreover this lampshade cover mouth inwall is provided with the taperedchromeplatedbezel 3 of annular, and the illumination light intensity of the light fixture of LED with the loss that minimizing diffuses, is improved in this taperedchromeplatedbezel metallizing material reflecting layer, or fluorescent powder material, monochrome or colored reflecting layer.Outer wall is provided with helicitic texture or buckle so that fastening lampshades, and the taperedchromeplatedbezel of above-mentioned annular can be along the cover wall towards a cover mouthful attenuation gradually, forms a muscle rib; Also can make things convenient for the fixing of lampshade; And prevent that being used to connect fixing colloid too much overflows, therefore, installation and maintenance is convenient.
To sum up, this LED bulb lamp lampshade is not only breakage-proof, dustproof, anti-aging, and has frosted finish effect, and bright dipping is evenly soft, free from glare, and light emission rate is high, and processing mode is simple, and is safe and reliable; Above-mentioned a kind of LED bulb lamp lampshade is compared with incandescent lamp tube or low-voltage fluorescence fluorescent tube, and the light range of scatter that comes out is wider, extensively is suitable for the luminous intensity distribution of various indoor illumination light fittings.
The above embodiment has only expressed several kinds of embodiments of the utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.
