Double-deck multiaspect reflector and have the flashlight and the light fixture of this reflector
Technical field
The utility model relates to and has reflector reflective and the optically focused effect, and the flashlight and the light fixture that have this reflector.
Background technology
Flashlight is a ligthing paraphernalia commonly used in people's daily life, the work.The reflector that uses in the common flashlight is made up of a parabola and the illuminator that is positioned at the parabolic focus center.Along with light emitting diode more and more widely use in illumination, the light emitting diode that the bulb in the flashlight is had advantage such as energy-conservation, durable gradually substitutes; Because the brightness of monomer light emitting diode is limited, a flashlight need use a plurality of light emitting diodes usually, and traditional can not satisfy instructions for use by a parabolic reflector of forming.
The utility model content
Primary and foremost purpose of the present utility model provides a kind of double-deck multiaspect reflector a plurality of illuminators, that the optically focused reflecting effect is good that is applicable to.The further purpose of the utility model provides a kind of flashlight and light fixture that has this bilayer multiaspect reflector.
For reaching above-mentioned primary and foremost purpose, the utility model adopts following technical scheme: this double-deck multiaspect reflector comprises reflection shield and illuminator, and reflection shield is made up of outer reflection shield and internal layer reflection shield; Described outer reflection shield is formed by connecting by a plurality of parabolas, and each paraboloidal focus place is fixed with the outer illuminator of horizontally set separately, the light that each outer illuminator sent by this corresponding parabolic reflector after forward penetrate and to be combined to form outer reticle circle; The axis of outer reflection shield inboard is provided with one by the parabolic internal layer reflection shield that forms independently, internal layer reflection shield focus place is fixed with the interior illuminator that a forward is provided with, the light that interior illuminator sends penetrates through internal layer reflection shield reflection forward, forms a branch of light beam that is positioned at described outer reticle circle middle part; Outer reticle circle and interior light beam are combined to form evenly complete circular light beam.
As preferred version, described outer reflection shield is formed by connecting by three to six parabolas.
Described inside and outside illuminator is preferably light emitting diode.Certainly, illuminator also can be a bulb.
The double-deck multiaspect reflector of the utility model is substituted existing reflector be contained on the flashlight, can constitute a kind of new-type flashlight.
The double-deck multiaspect reflector of the utility model is substituted existing reflector be contained on the light fixture, can constitute a kind of new-type light fixture.
Double-deck multiaspect reflector of the present utility model, the directly corresponding separately parabolic irradiation on the outer reflection shield of outer field a plurality of outer illuminator horizontally set, light in the effective lighting angle scope of each outer illuminator is all in the pairing parabola, all be reflected and be the forward ejaculation, form the outer reticle circle that light intensity is bigger, effectively utilized the bigger characteristics of luminous intensity on the axis in the outer illuminator angular field of view, be enhanced about more than once than the luminous intensity of the reflective form of tradition.The light that interior illuminator sent forms circular light beam forward and penetrates behind internal layer reflection shield optically focused, fall into above-mentioned outer reticle circle central authorities, and the optically focused that makes outer reflection shield is circle, real and evenly more.Because the light intensity at outer reticle circle middle part is that the light that is sent by inside and outside illuminator is formed by stacking after reflection, thereby its intensity is especially big, can improve its visual range when making telecurie irradiation.
Double-deck multiaspect reflector of the present utility model is contained in the new-type flashlight that constitutes on the flashlight, and spotlight effect is good, light intensity is big, save electric energy, uses more attractive in appearance, economical and practical.Equally, double-deck multiaspect reflector of the present utility model also can be contained in and constitute new-type light fixture on other light fixture.

Fig. 3 is the structural representation of the another kind of embodiment of double-deck multiaspect reflector of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is further described.
As shown in Figure 1, reflector of the present utility model is by outer reflection shield 1, internal layer reflection shield 2 and inside and outside lumination of light emitting diode body 3 ", 3 ' form.Outer reflection shield 1 is formed by connecting by three parabolas, there is the light emitting diode of horizontally set (promptly outer illuminator 3 ') separately at each paraboloidal focus place, the light that each outer illuminator 3 ' sent is after corresponding parabolic reflector, form a branch of directional light forward and penetrate, light path is shown in arrow among Fig. 2.Each outer illuminator 3 ' formed directional light constitutes an outer reticle circle.Inboard at outer reflection shield 1, an internal layer reflection shield 2 is arranged, it is an independence, complete parabola, be the light emitting diode that is provided with of a forward (illuminator 3 promptly in ") at this paraboloidal focus place; illuminator 3 in this " a branch of parallel beam of light forward ejaculation of formation after internal layer reflection shield 2 is reflective of the light that sent, drop on the central authorities of outer refractive body 3 ' formed outer reticle circle, improved the optically focused reflecting effect of whole reflector.It is bigger that outer reticle circle and interior light beam are combined to form the light intensity area, evenly the light beam of complete circle.
As shown in Figure 3, this reflector is equally by outer reflection shield 1, internal layer reflection shield 2 and inside and outside illuminator 3 ', 3 " form.Different is that outer reflection shield 1 is formed by connecting by four parabolas.
Certainly, as required, outer reflection shield 1 can be by five, six, seven ... be formed by connecting etc. a plurality of parabolas.
Adopt double-deck multiaspect reflector of the present utility model to substitute the reflector that has now in the flashlight, promptly constitute a kind of new-type flashlight, its optically focused reflecting effect is good, saves electric energy, and visual range is far away.
Double-deck multiaspect reflector of the present utility model can be applicable to equally priming illumination light fixtures such as Down lamp, shot-light with or mobile illuminating lamp such as head lamp, dynamo lighting set, portable lamp, camping lamp on.
The above-mentioned specific embodiment is the preferred embodiments of the present invention; can not limit claim of the present invention; other any change or other equivalent substitute mode that does not deviate from technical scheme of the present invention and made is included within protection scope of the present invention.
