Abstract
The utility model relates to a reflector with multiple mirror planes for a lamp, wherein a plurality of small reflecting convex faces are arranged on the inner surface of the reflector. Since the surface of each small arc reflecting convex face is used as a reflecting mirror, luminous efficiency of a light source of the lamp is evidently improved after the light source is reflected. Besides, the reflector can be used with various light sources and lamps, light reflectivity of the light source can be up to 80% or more, and is 30 % higher than that of a conventional reflector, and when in use, the lamp cannot glare, and luminance of an illuminating side is uniform. Further, the reflector with the multiple mirror planes for the lamp is long in service life, energy-saving and environment-friendly and the like, and is more suitable for being widely popularized and used due to the fact that sight of people working and studying under the lamp in the long term can be protected.
Description
Technical field
The utility model relates to a kind of reflection shield of lighting, particularly relates to a kind of many minute surfaces light fitting reflecting cover.
Background technology
General light fixture all has reflection shield, but reflective surface does not have specialized designs, particularly the simple plane reflection can only be carried out in light source irradiation output face back, and to the basic areflexia of light that bulb upwards penetrates, effective luminous efficiency of whole light fixture is had only about 50%.Reach certain irradiation brightness, only add high-powerly, cause waste of energy.And the dazzle of high power light source is serious, and brightness irregularities can damage the long-term personnel's that work, learn under this light eyes.
This shows that above-mentioned existing light fitting reflecting cover obviously still has inconvenience and defective, and demands urgently further being improved in structure and use.How to found and a kind ofly can improve light efficiency to greatest extent, free from glare when light fixture is used, shadow surface brightness are even, are more conducive to many minute surfaces light fitting reflecting cover of the new structure of energy-saving and environmental protection, one of real important research target that belongs to current industry.
The utility model content
The technical problems to be solved in the utility model provides a kind of many minute surfaces light fitting reflecting cover, make it can improve light efficiency to greatest extent, free from glare when light fixture is used, shadow surface brightness are even, are more conducive to energy-saving and environmental protection, thereby overcome the deficiency of existing light fitting reflecting cover.
For solving the problems of the technologies described above, a kind of many minute surfaces light fitting reflecting cover of the utility model, its inner surface is provided with the little convex surface of a plurality of reflections.
As a kind of improvement of the present utility model, also be provided with the light source installing hole on the described reflection shield.
The little convex surface of described reflection is a circular arc.
The little convex surface of described reflection is uniformly distributed on the inner surface of reflection shield.
The little convex surface of described reflection is coated with highly reflecting films.
Described highly reflecting films are vacuum coating or electrodeposited chromium.
It is plastics or aluminum alloy material.
After adopting such structure; the utility model makes the little convex surface of each circular arc become reflective mirror; obviously improve lamp light source effective luminous efficiency after reflection; and can supporting various light sources and light fixture use; the light reflection efficiency of light source is reached more than 80%; higher more than 30% than classical inverse light shield reflectivity; and free from glare when light fixture uses, shadow surface brightness are even; have plurality of advantages such as long service life, energy-saving and environmental protection; also help simultaneously to protect and under this light, work, learn personnel's eyesight for a long time, thereby be more suitable for extensively promoting the use of.
Description of drawings
Above-mentioned only is the general introduction of technical solutions of the utility model, and for can clearer understanding technological means of the present utility model, the utility model is described in further detail below in conjunction with accompanying drawing and the specific embodiment.
Fig. 1 is the structural representation of many minute surfaces of the utility model light fitting reflecting cover.
Fig. 2 is that the A-A of Fig. 1 is to cross-sectional view.
The specific embodiment
See also Fig. 1, shown in Figure 2, many minute surfaces of the utility model light fitting reflecting cover, the surface is provided with the little convex surface 2 of a plurality of reflections within it.
This reflects little convex surface 2 and is preferably circular arc, is uniformly distributed on the inner surface of reflection shield, and can be at highly reflecting films such as the surface-coated vacuum coating of reflecting little convex surface 2, electrodeposited chromiums.
Preferable, the little convex surface 2 of the reflection of many mirror reflectors of the utility model and inner surface thereof, can be by direct machine-shapings of technology such as plastic injection-moulded, aluminium alloy punching press, aluminium alloy compression castings, and can on top, side or other any position of reflection shield, also offer light source installing hole 1 as required.
Many minute surfaces of the utility model light fitting reflecting cover; can with the supporting use of any ordinary lamp and lantern; when light source luminescent; on the reflection shield each reflects little convex surface promptly becomes reflective mirror; make the light of irradiation backward carry out multidirectional reflection; reflection efficiency reaches more than 80%; higher more than 30% than classical inverse light shield reflectivity; improve light efficiency to greatest extent; and free from glare when light fixture is used; shadow surface brightness is even; has long service life; energy-conservation; the advantage of environmental protection also helps protection to work under this light for a long time simultaneously; study personnel's eyesight, product market potential tool is big.
The above; it only is preferred embodiment of the present utility model; the particularly design of light source installing hole; can transform to other side according to the light fixture demand; be not that the utility model is done any pro forma restriction; those skilled in the art utilize the technology contents of above-mentioned announcement to make a little simple modification, equivalent variations or modification, all drop in the protection domain of the present utility model.
