Abstract
The invention discloses a lamp reflector and a lamp using the same. The lamp reflector comprises a main reflector and an assistant reflector, wherein the main reflector is a condensing reflector; the assistant reflector is a floodlight reflector and is arranged on the main reflector; the height of the assistant reflector is less than 1/3 of that of the main reflector; and the lamp lie in using the lamp reflector. The lamp reflector ensures the ideal light type of a main light source and an assistant light source, does not add the size of the integral lamp, and is economical and practical.
Description
Technical field
The present invention relates to lighting field, more particularly, relate to a kind of light fixture reflector and use the light fixture of this reflector.
Background technology
Existing light fixture, especially portable lamp generally only are furnished with a light source, and with the suitable reflector of this light source.When this light fixture occurs extinguishing unusually at light source, will have influence on operating personnel's operate as normal, the serious life security that will jeopardize the operating personnel, such as, the miner of underground work.
In order to address the above problem, some solutions have also appearred on the market, such as the light source setting of adopting main light source and secondary light source to combine, for size and the saving cost of controlling lamp holder, general is carried out luminous intensity distribution design to main light source, and secondary light source there is no the luminous intensity distribution design, and only requiring can be bright, when damaging, main light source plays a role in lighting, but no luminous intensity distribution design can cause serious light intensity uneven illumination even, spot center can occur for empty, bright line much clearly waits phenomenon, influence illuminating effect, thereby influence normal operation, if the major-minor light source carries out the luminous intensity distribution design respectively, can increase the size of head lamp again, carry inconvenience.
Summary of the invention
The technical problem to be solved in the present invention is that the inhomogeneous defective of above-mentioned secondary light source intensity of illumination at prior art provides a kind of light fixture reflector, makes the major-minor light source all reach desirable light distribution effect not increasing under the lamp holder size situation.
The technical solution adopted for the present invention to solve the technical problems is: construct a kind of light fixture reflector, comprise main reflector and secondary reflector, it is characterized in that, described main reflector is the optically focused reflector, described secondary reflector is a floodlight reflector, described secondary reflector is arranged on the main reflector, and the height of described secondary reflector is less than 1/3 of main reflector height.
In light fixture reflector of the present invention, the parabola that is shaped as of the light reflection surface of described main reflector rotates the parabola that forms around axis.
In light fixture reflector of the present invention, described parabolic equation is: X2=20Y.
In light fixture reflector of the present invention, the light reflection surface of described secondary reflector is shaped as the continuous parabolic curve of multistage and rotates the multistage parabola that forms around axis, and described parabolic shape and every intersegmental ratio are definite with the scope zone that will shine according to the light distribution on the light-source angle.
In light fixture reflector of the present invention, the parabola that described multistage links to each other is three sections continuous parabolas.
In light fixture reflector of the present invention, described three sections continuous parabolic height from open section, interlude on earth the ratio of section be 2: 2: 1.
In light fixture reflector of the present invention, the light reflection surface of described secondary reflector is Gauss (Gaussian) or Lang Baite (Lambertian) handles.
In light fixture reflector of the present invention, the number of described secondary reflector is one or more.
A kind of light fixture that uses above-mentioned light fixture reflector.
Implement light fixture reflector of the present invention and use the light fixture of this reflector, have following beneficial effect: secondary reflector is done the multisection type design, every section shape and height make secondary light illumination even according to light distribution on the light-source angle and the scope zone design that will shine; The light reflection surface of secondary reflector is Gauss (Gaussian) or Lang Baite (Lambertian) handles, and is equivalent to the pasta reflector, plays the effect of floodlight; The height of secondary reflector under the situation that does not increase the light fixture overall dimensions, guarantees main light source and the desirable light type of secondary light source less than 1/3 of main reflector height, and is economical and practical.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is the preferred embodiment front view of light fixture reflector of the present invention;
Fig. 2 is the preferred embodiment upward view of light fixture reflector of the present invention;
Fig. 3 is the light path schematic diagram of secondary reflector of the preferred embodiment of light fixture reflector of the present invention.
The specific embodiment
As depicted in figs. 1 and 2, in the preferred embodiment of light fixture reflector of the present invention, comprise main reflector 100 and the secondary reflector 200 that is arranged on main reflector 100 bottoms, wherein main reflector 100 is the optically focused reflector, secondary reflector 200 is a floodlight reflector, the height of secondary reflector 200 is less than 1/3 of the height of main reflector 100, can not have influence on the light type of main reflector after so secondary reflector 200 and 100 combinations of main reflector, if greater than 1/3, the main light source center spot will produce little black hole, influence the illuminating effect of main light source.The light reflection surface of main reflector 100 is the optically focused parabola, and it is shaped as parabola and rotates the parabola that forms around axis, and preferred parabolic equation is: X
2=20Y, the focus of light reflection surface is positioned at (0,5), when light source is positioned at focus, penetrating the light that goes after the reflecting surface reflection is directional light, and hot spot is fine, and illumination is even, generally in actual applications, light source 0.2mm～2mm can be adjusted forward, the very center spot of optically focused can be obtained like this.
The spot center of using the secondary light source of the mine lamp that the present invention preferably implements embodiment is the circular light spot of full angle 15 degree, and the center is very bright in the hot spot, and other parts are very even, have good illuminating effect.
Secondary reflector is two in the light fixture reflector preferred embodiment of the present invention, is symmetrically distributed, and secondary reflector number can be for one or more.
The preferred embodiment of light fixture of the present invention is the light fixture of the reflector of use light fixture reflector preferred embodiment of the present invention.
The secondary reflector of light fixture reflector of the present invention is done multisection type design, and every section shape and height make secondary light illumination even according to the light distribution on the light-source angle and the scope zone design that will shine; The light reflection surface of secondary reflector is Gauss (Gaussian) or Lang Baite (Lambertian) processes, and is equivalent to the pasta reflector, plays the effect of floodlight; The height of secondary reflector in the situation that does not increase the light fixture overall dimensions, guarantees main light source and the desirable light type of secondary light source less than 1/3 of main reflector height, and is economical and practical.
