Description

A kind of LED bulb and lampshade thereof

Technical field

The utility model relates to a kind of LED bulb and lampshade thereof, relates in particular to a kind of with LED bulb and the lampshade thereof of a plurality of LED monomers as light source.

Background technology

In recent years, because comparing other illuminator, LED (light emitting diode) has power saving, advantages such as long service life, therefore be widely used on the lighting gradually, yet the illumination of LED monomer is subject to the technical bottleneck in the power increase, therefore to increase the brightness of lighting, just must increase the usage quantity of LED monomer, and LED monomer and traditional illuminator difference are, the light source that it produced has the characteristic that concentrates on the specific region angle, in case when a plurality of LED monomer is set on same lighting, just have multiple light source, the problem of many bright spots produces, and multiple light source, many bright spots are easy to cause irradiation inhomogeneous, shone thing has the situation of multi shadow, and make the beholder dazzling easily, even visual impairment.

See also Figure 1 and Figure 2, be existing light fixture schematic diagram (), (two) with a plurality of LED monomers, the general technological means of the shortcoming that produces when improving the multiple light sources irradiation of a plurality of LED monomer 90, as on first lampshade that figure is shown in 91 some refraction lines 92 being set, so that the light source that each LED monomer 90 produced can see through the refraction action of refraction line 92 and spread; And for example shown in Figure 2, lampshade 91 is carried out the mode that cloudy surface is handled, so that the light source that each LED monomer 90 is produced can spread irradiation in gentle mode of closing.

Yet, above-mentioned prior art uses so that the means of light source diffusion, what presented improves effect and comes desirablely not as expecting, for multiple light source, many bright spots, shine inhomogeneous, shone thing has problems such as multi shadow still can't effectively to suppress, after studying, the utility model people finds, prior art is improved effect and is not as the main cause of expecting, when a plurality of LED monomers produce light source, will project the luminous point that some light are concentrated earlier at the lampshade inner face, hot spot, then the dark space of illuminance deficiency between luminous point and the luminous point, when described wait luminous point to produce after, on lampshade, be provided with the refraction line or in addition cloudy surface to handle the diffusion effect that is produced also just quite limited naturally.

In view of this, the inventor studies and improves at the bulb that adopts a plurality of LED monomers, and then designs a kind of LED bulb and lampshade thereof that can effectively improve multiple light source irradiation shortcoming.

Summary of the invention

Main purpose of the present utility model is to provide a kind of LED bulb and lampshade thereof, and the light source that a plurality of LED monomers are given out in the LED bulb can evenly be spread and fusion mutually.
