Abstract
The utility model discloses a lighting device, which is composed of a light focusing reflector whose inner chamber presents an ellipsoid surface, a light source, and a lamp cover. The lamp cover is composed of a concave lens, and a convex lens on the periphery of the concave lens, which can project the emitted light source on a focusing reflector or not; a luminous beam used for illumination is emitted by the convergence of the light focusing reflector, and the lamp cover. The utility model can be widely used for illumination equipment of various carrying vehicles, and illumination devices.
Description
The utility model belongs to lighting device.
Lighting apparatus such as the illuminating lamp of present various motor vehicles, mine lamp, searchlight and flashlight, its reflection shield adopts parabola more, on paraboloidal focus, bulb is set, utilize paraboloidal optical characteristics, with a part of light path that projects on the reflection shield, after assembling, project the direction that needs illumination again, and another part can not project the light path on the reflection shield, then scatters to other directions and has gone, and can not be fully used.
The purpose of this utility model is to provide a kind of ellipsoid light path concentration illumination device.
The purpose of this utility model is achieved in that lampshade is made of concavees lens and convex lens, and forms one, and inner chamber is the optically focused reflection shield of ellipsoid, joins by the outer rim of outer rim and lampshade, and light source is arranged at interior focus place.
The utility model is the optically focused reflection shield of ellipsoid because of adopting inner chamber, the lampshade that constitutes by concavees lens and convex lens, can be with the light path that projects or do not project on the optically focused reflection shield, all obtain and to send for illuminating light beam by coalescence, overcome parabolic reflection shield and can not assemble the shortcoming of scattering light path, can be extensively as the lighting apparatus and the various illuminations of various forms of transport.
Concrete structure of the present utility model is described further in conjunction with the accompanying drawings.
It is planar that the inner chamber of optically focused reflection shield 3 is ellipsoid, interior focus 2 places at optically focused reflection shield 3 are provided with bulb 1 or filament, the centre of lampshade 5 is concavees lens 6, around it is convex lens, concavees lens 6 and convex lens constitute one, lampshade 5 is arranged on the left side of outer focus 7, lampshade diameter 10 is perpendicular to the optical axis 8 of interior focus 2 and outer focus 7, the focus of concavees lens 6 can coincide with the outer focus 7 of optically focused reflection shield 3, or be positioned near the outer focus 7 the optical axis 8, concavees lens diameter 9 equates with light path 4 diameter of sections that are reflected in by optically focused reflection shield 3 on the lampshade 5, the focus of convex lens can coincide with the interior focus 2 of optically focused reflection shield 3 on the lampshade 5, or be positioned near the focus 2 the optical axis 8, lampshade diameter 10 should be greater than light path 4 diameter of sections that are reflected in without optically focused reflection shield 3 on the lampshade 5, when big, lampshade 5 can be made Fresnel lens as the diameter of lampshade 5.
Claims (1)
1, a kind of ellipsoid light path concentration illumination device is characterized in that lampshade 5 is made of concavees lens 6 and its peripheral convex lens, and forms one that inner chamber is the optically focused reflection shield 3 of ellipsoid, joins by the outer rim of outer rim and lampshade 5, and light source 1 is arranged at interior focus 2 places.
