Fig. 2 is the structural representation of second embodiment of the utility model lighting device.
Fig. 3 is the structural representation of the 3rd embodiment of the utility model lighting device.
The specific embodiment
Further specify the specific embodiment of the present utility model below in conjunction with accompanying drawing.
As Fig. 1, Fig. 2, shown in Figure 3, a kind of lighting device of the utility model, it comprises reflector 12/22/32 with light reflection function, be positioned at described reflector one end and be positioned at described reflector axial location light source 10, be positioned at the lens 15/28/33 that the reflector other end is used for refraction.This lighting device is assembled the reflection of the scattered beam of light source peripheral region by reflector and is shone lens, and scioptics reflect directional light, thereby can assemble more large tracts of land scope scattered light, thereby strengthen illumination capability, exposure intensity, the brightness of lighting device.
More preferably, with reference to shown in Figure 1, described reflector 12 longitudinal sections are the half ellipse, and described light source 10 is positioned at oval focus place, and described lens 15 are concavees lens.The light that oval face mirror (be axle with the long axis of ellipse, ellipse is rotated the solid figure that 180 degree form, its inner surface is all made reflecting surface, hollow) can send certain focus all reflexes to another focus place; Position between two focuses arranges reflector, and reflector adopts ellipse that light is reflected into focus light and is incident upon concavees lens, and concavees lens become directional light with light refraction again.Thereby the scattered beam that can assemble wider area is penetrated ability thereby strengthen illumination, improves irradiation brightness, meets the luminous intensity requirement of remote illumination.
More preferably, the axial ratio of described ellipse is greater than 2, and namely the degree of depth of light cup is more than the twice of light cup opening radius, thereby thereby need not strengthen light rim of a cup footpath and only deepen reflector and reach the PAR that increases light and reach and strengthen optically focused brightness, reduce the overall product volume.
More preferably, described lens are plano-concave lens or biconcave lens, according to the requirement attractive in appearance of product, and the coupling requirement of focal position, select plano-concave lens or biconcave lens, select biconcave lens preferable when focal length is big.
More preferably, with reference to shown in Figure 2, described reflector 22 be the cover type, and described light source 10 is positioned at the wide mouth end face place of reflector 22, and described light source 10 sides are provided with the light that time reflector 24 launches reflector 22 and reflex to lens 28 again, and described lens 28 are convex lens.The light portion of light source 10 shines directly into lens 28 by the slot of reflector 22, and scioptics 28 refractions form collimated light beam and realize spotlighting again, and convex lens are focus with the light source.Other has part light to exceed the edge extent of convex lens, then will shine light less than convex lens at these irradiation fields (light scattering scope) and be reflected back near the light source inferior reflector with reflector, by inferior reflector light is reflexed to convex lens, thereby reach the brightness of enhancing optically focused thereby reach enhancing light-ray condensing rate with secondary reflecting cup reflection ray, improve illumination capability and intensity of illumination, meet remote light-struck requirement.
More preferably, be provided with flaring transparent area 26 between described reflector 22 and the described lens 28, thereby the extension distance enlarges the optical range that is subjected to of lens 28, increase diameter and the glazed area of lens 28, form peripheral short distance illumination and the combined Multi-function lighting device of central long-distance illumination.
More preferably, with reference to shown in Figure 3, the interior reflective longitudinal section profile of described reflector 32 is the parabola shaped of eccentric belt deflector angle, and described lens 33 are convex lens.Reflector 32 adopts the parabola of eccentric belt deflector angle to rotate a circle as cross section profile and forms reflective surface in the reflector, and light is reflected into one group has focus light to convex lens, and convex lens become directional light with light refraction again.Light source 10 exposes to convex lens and dwindles the light angle that light source is incident upon convex lens through refraction, strengthens astigmatic brightness thereby reach, and is fit to the requirement of short distance irradiation, has the dipped beam brightness of stronger short distance irradiation ability.
More preferably, described lens 33 are planoconvex spotlight or biconvex lens, for the requirement of attractive in appearance and focal length, select to meet the form of lens of product quality requirement.
More preferably, described light source 10 is incandescent lamp or LED lamp, and the LED light fixture has higher brightness and illumination capability, still can guarantee more long-range irradiation ability through reflection and refraction.
Above disclosed only is preferred embodiment of the present utility model, can not limit the interest field of the utility model certainly with this, and therefore the equivalent variations of doing according to the utility model claim still belongs to the scope that the utility model is contained.
