Abstract

The utility model discloses a lamp shade spreading film, which comprises a substrate layer and a spreading layer. The substrate layer is made of high temperature resistant transparent plastic materials. The spreading layer is composed of a plurality of ball bodies which can use glass balls, acryl balls, or polyamine ethyl ester ball bodies, etc. The spreading layer can be coated on the substrate layer by adhesive. The spreading layer can also be coalesced on the substrate layer by making use of the technology, for example, the spraying operation, the UV adhesive coating, or the printing operation, etc. The utility model can reach the lamp shade with the functions that the lamp shade can make uniform light spread; the lamp shade can isolate from glare light and can reach the feel of making light rays soft and comfort; the internal uniform optics can carry out diffraction; light energy reaching each position can effectively carry out diffraction and can be stored so as to more reduce the flicker performance of the light source; after the inner light source and the outer light source of the lamp shade carry out the diffraction and the spreading operation, illumination and brightness of the light source can not form attenuation, but can be increased, so that luminous efficacy of the light source can be fully showed.

Description

The diffusion barrier of lampshade

Technical field

The utility model relates to a kind of diffusion barrier of lampshade, refers in particular to a kind of lamp light source the place ahead that is arranged on, and can completely cut off dazzle, lowers the flicker of light source, low light decay and fully show the diffusion barrier of light source light-emitting efficiency.

Background technology

What conventional light source was emphasized is enough bright all right, and the light source of a new generation then is comfortable, and causes the tired discomfort of eye will injure a dazzle immediately when reading.According to statistics, 43% student feels the most uncomfortable when reading be the reflective problem of dazzle, and the general commercially available light fixture in market at present all can't effectively solve glare problem, causing because dazzle is the principle of light reflection, is not that fluorescent tube or ballast performance can be improved.

Common dazzle has three kinds, comprise contrast dazzle, direct glare and reflected glare, except the contrast dazzle, good light fixture should be able to improve direct glare and reflected glare, especially the general title of modal reflected glare is reflective, under normal reading angle, can't avoid, because of it occurs in incidence angle (by the incident angle of light source projects to reading object) and angle of reflection (reflexing to the angle of reflection of eye) angle same.

The most common example that utilizes the polarisation principle to solve disability glare in the daily life is exactly sunglasses, though this polaroid can completely cut off dazzle, has but also reduced simultaneously light over half.Because every bundle light all contains vertical light and directional light, two partly respectively account for half, and can cause dazzle have only directional light partly, general polaroid is that the directional light of half is isolated fully with this, so in the time of user's Wearing sunglasses,, also felt deepening simultaneously though feel comfortable not dazzling.But this polaroid and being not suitable for is used for improving the dazzle that light fixture such as desk lamp causes, because dark excessively light source and be not suitable for reading.

Develop a kind of light transmission (Diffusive) reflection-type optical filter though 3M is up-to-date, can completely cut off reflected glare, but direct glare does not overcome fully, still can be visual to lighting source, it is a Ge Jia glazing transmission optics film about the reflection-type optical filter, make each bundle light evenly transfer to the full wafer optical filter, and do not have dazzling direct glare relatively.But this optical filter can make that still the illumination intensity of light source decay is many.

As from the foregoing, above-mentioned known light fixture on reality is used, obviously has inconvenience and exists with shortcoming, and can wait to be improved.

So the utility model people is at above-mentioned amendatory shortcoming, propose a kind of reasonable in design and effectively improve the utility model of above-mentioned shortcoming.

Goal of the invention

Main purpose of the present utility model is to provide a kind of diffusion barrier of lampshade, removes to completely cut off reflected glare, and reduces outside the direct glare, also reaches the soft comfort of light, and can make and almost not decay of illumination intensity of light source make light fixture more valuable.

Above-mentioned purpose of the present utility model is achieved in that the diffusion barrier of a kind of lampshade that the utility model provides, and this diffusion barrier is arranged on lamp light source the place ahead, comprising: a substrate layer, make by transparent plastic material; And a diffusion layer, being constituted by most pearl bodies, it is engaged on the surface of this base material.

The diffusion barrier of lampshade described in the utility model, wherein, the plastic material of described substrate layer is layer of polyethylene terephthalate, layer of polycarbonate, polytetrafluoroethylene floor (PTFE, teflon layer) or acrylic layer.

The diffusion barrier of lampshade described in the utility model, wherein, described substrate layer is a sheet.

The diffusion barrier of lampshade described in the utility model, wherein, described pearl body is bead, acryl pearl or polyamine Ethyl formate pearl.

The diffusion barrier of lampshade described in the utility model wherein, is provided with adhesive phase between described diffusion layer and the substrate layer.

The diffusion barrier of lampshade described in the utility model wherein, is provided with adhesive linkage between described diffusion layer and the substrate layer, and described adhesive linkage is a sprayed coating.

The diffusion barrier of lampshade described in the utility model, wherein, the diffusion barrier of the lampshade described in the utility model of described diffusion layer and substrate layer is characterized in that, is provided with adhesive linkage between described diffusion layer and the substrate layer, described adhesive linkage is a printed layers.

The diffusion barrier of the lampshade that provides by the utility model is compared with known technology, can reach following function at least:

1, evenly light diffusion can completely cut off dazzle and reach the soft comfortable sensation of light.

2, the inner diffraction of uniform optics makes the effective diffraction of light energy preserve the flicker of more lowering light source.

3, the inside of lampshade and external light source diffraction can make the unattenuated increase on the contrary of light illumination and briliancy through after spreading, and fully show light source light-emitting efficiency.

Below, in conjunction with specific embodiments and accompanying drawing technical characterictic of the present utility model and technology contents are described in further detail, yet, shown in accompanying drawing only for reference with the explanation usefulness, be not to be used for limiting the utility model.
