Abstract
The invention relates to a reflecting shade plate for an LED illuminant, comprising an integral reflecting plate formed by sequentially connecting a plurality of reflecting bowl covers. The reflecting shade plate is characterized in that the reflecting plate is in a rectangular shape, and the side faces of the reflecting bowl cover are open at the edge part of two sides of the long sides of the rectangular shape. Compared with a tube lamp holder consisting of the LED illuminants with the same number, the invention has the advantages of stronger brightness, more uniform distribution of light rays, wider irradiation range, more reasonable and practical structure and easy assembly.
Description
Technical field
The present invention relates to a kind of reflector cover.
Background technology
The main light source of traditional fluorescent lamp is a fluorescent lamp, and heavy metal Hg is contained in this light source inside, and environment and end user's health is all had suitable threat.And shell is glass, and to fire prevention, protective cover must be installed in the demanding place of anti-explosion safety, and all there is very big inconvenience shock resistance and transportation aspect.Along with the succeeding in developing of development of semiconductor and super bright small-power white light LEDs, LED shows at signal as semiconductor light sources in recent years, back lighting, and aspects such as Landscape Lighting have obtained using widely.Semiconductor lighting has characteristics such as energy-saving and environmental protection, long service life, is called as the third generation lighting source after lightings such as incandescent lamp, fluorescent lamp.But the optical semiconductor volume source is little, the drive circuit complexity, and non-refractory, inner heat causes reasons such as light decay is serious, causes its fluorescent lamp product all to fail a large amount of production always.
Existing a kind of patent No. has proposed a kind of structure for the Chinese utility model patent that the CN200720066677.0 name is called " the general fluorescent tube that uses LED ": it uses LED (light emitting diode) as light source, the profile LED fluorescent tube of being made up of plastics transparent lamp shade, heat dissipation metal shell, circuit board, standard universal fluorescent lamp head etc. all identical with common fluorescent tube with installation dimension.Maximum characteristics are directly to replace common fluorescent tube, are applicable to various illumination occasions.But shortcoming is, do not establish reflection shield on the LED fluorescent tube, thus low with respect to the lighting tube brightness of same number of LED illuminator number, and the brightness of light has tangible strong and weak district, so its structure awaits to improve.
Though, also use the reflector cover widely in the fluorescent tube of some present employing LED, but, traditional reflector cover normally adopts a bowl formula, make light that the LED that is in the edge sends all convergence reflex come out, can't scatter out equably, cause easily between irradiated region and the non-irradiated region and have tangible boundary line, influence illuminating effect, the optically focused performance of reflector cover is good in addition, and scattering property is poor, zone between the adjacent reflector cover, cause easily at irradiated region and produce shade, also influence illuminating effect, require further improvement design.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of distribution of light that can impel illuminator more evenly and the reflecting shade plate that is used for the LED illuminator that range of exposures is more extensive, brightness is stronger at above-mentioned prior art present situation.
The present invention solves the problems of the technologies described above the first technical application scheme that is adopted: a kind of reflecting shade plate of the LED of being used for illuminator, it includes a plurality of reflector covers and is in turn connected into whole reflector, it is characterized in that reflector presents rectangular shape, position, both sides of the edge on long limit, reflector cover lateral opening.
As improvement, described reflector cover is to go up row to be arranged in parallel with crossover location with row down and to be in the same place, at least the whole reflector cover that is in the position, both sides of the edge on long limit is the honeycomb shape that presents substantially half that adopts lateral opening, and the centre is half taper type of indent.Like this can optically focused, again can be and astigmatism is improved illuminating effect by lateral opening, make irradiation more even.
Improve, the frustum face of described its adjacent indent of reflector cover is to intersect each other to form the indent camber line again, thereby constitutes substantially honeycomb shape or half honeycombed.Can significantly reduce juncture area between the adjacent reflector cover like this, thereby minimizing or elimination juncture area improve illuminating effect at the shade of irradiated region.
As preferably, the taper type of described indent and bottom surface angle are 30～80 degree, and the height of indent camber line from the reflector surface accounts for the frustum degree of depth 10～30%.
Improve again, be distributed with the reflecting beads that can change light emission direction and strengthen reflective scattering on described its concave surface of reflector cover.Described reflecting beads is chosen as spherical reflecting beads or box-shaped reflecting beads.
The present invention solves the problems of the technologies described above the second technical application scheme that is adopted: a kind of reflecting shade plate of the LED of being used for illuminator, it includes a plurality of reflector covers and is in turn connected into whole reflector, it is characterized in that reflector presents circle, at the circumferential edges position, reflector cover lateral opening.
As improvement, described reflector cover is to be concentric circles to be arranged in together, the whole reflector cover that is in the circumferential edges position at least be adopt lateral opening present the partial cells shape substantially, the centre is the local taper type of indent.Like this can optically focused, again can be and astigmatism is improved illuminating effect by lateral opening, make irradiation more even.
Improve, the frustum face of described its adjacent indent of reflector cover is to intersect each other to form the indent camber line again, thereby constitutes substantially honeycomb shape or partial cells shape.Can significantly reduce juncture area between the adjacent reflector cover like this, thereby minimizing or elimination juncture area improve illuminating effect at the shade of irradiated region.
As preferably, the taper type of described indent and bottom surface angle are 30～80 degree, and the height of indent camber line from the reflector surface accounts for the frustum degree of depth 10～30%.
Improve again, be distributed with the reflecting beads that can change light emission direction and strengthen reflective scattering on described its concave surface of reflector cover.Described reflecting beads is spherical reflecting beads or box-shaped reflecting beads.
Compared with prior art, the invention has the advantages that: adopt the reflector cover that on the LED illuminator, is equipped with lateral opening, its advantage is that the reflector cover of edge can scatter out light with different directions, so not only make light issue evenly, but also effectively light is utilized once more and strengthened the brightness of tube lamp holder; And do rational improvement at the intersection of adjacent reflector cover, eliminate the shade projection of juncture area at irradiated region as far as possible, improve illuminating effect, also have, the design's reflecting beads that on the concave surface of reflector cover, distributes, thereby the brightness of tube lamp holder and the even distributed degrees of light have further been strengthened, so stronger with respect to its brightness of tube lamp holder that same number LED illuminator is formed, distribution of light is more even, range of exposures is more extensive, structure is more reasonable and practical, easily assembling.
