Abstract
A reflection lampshade structure of the remote lighting device as high intensity gas discharge lamp, which is composed of a reflection lampshade of paraboloid, wherein the front edge of the lampshade is fixedly connected with a light adsorption ring of cylinder shape, the wall of the light adsorption ring is provided with a corrugated axial section. The utility model arranges a light adsorption ring at the front edge of a paraboloid reflection lampshade to adsorb the diffraction virtual photon and refraction stray light of the reflection lampshade, to realize a clear light ring of a light source focused and reflected from the lampshade, and the light ring has no virtual photon and refraction stray light around. The reflection lampshade structure has simple structure and application.
Description
Technical field:
The utility model relates to electricity field, relates in particular to the electric consumption on lighting device, particularly a kind of reflection shield structure that is used for high-intensity gas discharge lamp remote illumination device.
Background technology:
High-intensity gas discharge lamp, the English HID that is called for short, the two end electrodes ionization inert gas by lamp comes luminous, so the luminous efficiency height of lamp is three times of the luminous common Halogen lamp LED of tungsten filament, it is well-illuminated to produce powerful light.Because the well-illuminated height of light of HID lamp, volume is less, can make the mobile portable light source (as flashlight etc.But the HID lamp is a spot light, needs could realize by focus reflection the effect of remote illumination, and can form vignette and refraction veiling glare after the light source reflection, and the ring of light of formation is unintelligible.
Summary of the invention:
The purpose of this utility model provides a kind of reflection shield structure that is used for high-intensity gas discharge lamp remote illumination device, and described this high-intensity gas discharge lamp will solve the unsharp technical problem of the ring of light that high-intensity gas discharge lamp forms in the prior art when remote illumination is used.
This reflection shield structure that is used for high-intensity gas discharge lamp remote illumination device of the present utility model is made of a reflection shield, wherein, it is parabolic that described reflection shield is, be fixedly connected with an extinction circle on the forward position of reflection shield, described extinction circle is cylindrical tube shape, and the tube wall of extinction circle has undulatory axial cross section.
Further, the internal diameter of described extinction circle equals the internal diameter in reflection shield forward position.
Further, described reflection shield bottom outside is fixedly connected with a knob, described knob is tubular, be provided with a socket in the through hole of reflection shield bottom, along the circumferential direction be provided with three ramp terraces on the outer wall of described socket continuously, knob sleeve is combined on the outer wall of socket, along the circumferential direction has been evenly distributed three ramp terraces on the inwall of knob, and the ramp terrace of knob inwall cooperates with the ramp terrace of socket outer wall.
Operation principle of the present utility model is: light source reflects collimated light beam under the focussing force of reflection shield, the no refract light of ring of light periphery that the reflection back forms.The extinction circle of reflection shield front end sponges vignette and the refraction veiling glare that the reflection shield diffraction produces.It is clear to make that light source passes through the ring of light that forms behind the reflection shield focus reflection, the ring of light the no vignette of periphery and reflect veiling glare.The knob of reflection shield bottom cooperates with socket, can regulate the position of light source center in reflection shield of high-intensity gas discharge lamp, so that reach best focusing effect.
The utility model and prior art contrast, and its effect is actively with tangible.The utility model is provided with the extinction circle in the forward position of parabolic reflection shield, and vignette and refraction veiling glare that the reflection shield diffraction is produced sponge.It is clear to make that light source passes through the ring of light that forms behind the reflection shield focus reflection, the ring of light the no vignette of periphery and reflect veiling glare.Simple in structure, easy to use.
Description of drawings:
Fig. 1 is the schematic diagram that is used for the reflection shield structure of high-intensity gas discharge lamp remote illumination device of the present utility model.
Fig. 2 is the reflection shield of the reflection shield structure that is used for high-intensity gas discharge lamp remote illumination device of the present utility model and the position view of high-intensity gas discharge lamp.
The specific embodiment:
As depicted in figs. 1 and 2, the reflection shield structure that is used for high-intensity gas discharge lamp remote illumination device of the present utility model is made of high-intensity gas discharge lamp 4 and rectifier (not shown), described high-intensity gas discharge lamp 4 is electrically connected by the conductor (not shown) with rectifier, wherein, the periphery of described high-intensity gas discharge lamp 4 is provided with a reflection shield 1, it is parabolic that described reflection shield 1 is, the light source center of high-intensity gas discharge lamp 4 is arranged on the central axis of reflection shield 1, and between the bottom of the plane in reflection shield 1 forward position and reflection shield 1, the plane in the light source center of high-intensity gas discharge lamp 4 and reflection shield 1 forward position, be provided with between the bottom of reflection shield 1 at interval, be fixedly connected with an extinction circle 3 on the forward position of reflection shield 1, described extinction circle 3 is cylindrical tube shape.
Further, the tube wall of described extinction circle 3 has undulatory axial cross section.
Further, the internal diameter of described extinction circle 3 equals the internal diameter in reflection shield 1 forward position.
Further, the light source center of described high-intensity gas discharge lamp 4 is arranged on the focus of reflection shield 1.
Further, described high-intensity gas discharge lamp 4 is arranged in the socket 5, along the circumferential direction be provided with three ramp terraces on the outer wall of described socket 5 continuously, described reflection shield 1 bottom outside is fixedly connected with a knob 6, described knob 6 is tubular, knob 6 is linked on the outer wall of socket 5, along the circumferential direction has been evenly distributed three ramp terraces on the inwall of knob 6, and the ramp terrace of knob 6 inwalls cooperates with the ramp terrace of socket 5 outer walls.
The course of work of present embodiment is: light source reflects collimated light beam under the focussing force of reflection shield 1, the no refract light of ring of light periphery that the reflection back forms.The extinction circle 3 of reflection shield 1 front end sponges vignette and the refraction veiling glare that reflection shield 1 diffraction produces.It is clear to make that light source passes through the ring of light that forms behind reflection shield 1 focus reflection, the ring of light the no vignette of periphery and reflect veiling glare.The knob 6 of reflection shield 1 bottom cooperates with socket 5, can regulate the position of light source center in reflection shield 1 of high-intensity gas discharge lamp 4, so that reach best focusing effect.
