Abstract
The invention relates to a reflector for an LED mine lamp; a reflecting surface comprises m*n isosceles trapezoid reflection planes consisting of n+1 longitudinal broken lines with m-1 break points and m+1 horizontal broken lines with n-1 break points which are crossed; the longitudinal broken lines start from one line, rotate around the axis OO', and one longitudinal broken line is obtained after every 180/n degree is rotated, the finally obtained n+1th longitudinal broken line and the first longitudinal broken line are located the same installation plane which passes through the axis OO' and symmetric based on the axis OO', and other n-1 longitudinal broken lines are located on the same side of the installation plane, and the m+1 horizontal broken lines are mutually in parallel. The reflector for the LED mine lamp improves the lighting efficiency of the LED mine lamp and the light source utilization rate of the mine lamp, and eliminates the defect that a traditional mine lamp forms uneven spots in a lighting area.
Description
Technical field
The present invention relates to a kind of light fixture and use reflector, particularly relate to a kind of LED mine lamp and use reflector.
Background technology
Mine lamp is the indispensable lighting apparatus of mine workman.The tradition mine lamp adopts bilux bulb as lighting source, and not only power consumption is big, and bulb when using temperature too high, have potential safety hazard.
LED (light emitting diode) has advantages such as cold light source, energy-saving and environmental protection, safety; Adopt the mine lamp of led light source to have long service life, advantage such as not fragile; And led light source does not have conventional light source to the luminous shortcoming in four sides; The characteristics of luminescence of its high directivity can promote the light extraction efficiency of light fixture, has therefore generally used the LED mine lamp to substitute traditional mine lamp under the mine at present.
But because the employing of existing LED mine lamp is common circular reflector, its illumination uniformity is also not ideal enough, and there is aberration in LED light, so in irradiation area, color spot can occur, influences normal operation.
Summary of the invention
The purpose of this invention is to provide a kind of LED mine lamp and use reflector, to solve the shortcoming that present mine lamp light extraction efficiency is low, there is color spot in irradiation area.
In order to solve above technical deficiency, the present invention adopts following technical scheme:
A kind of LED mine lamp is used reflector; Be fixedly mounted on the led chip base; Be used for led chip and go out reflection of light; Its reflecting surface has the longitudinal broken line of m-1 break by the n+1 bar and transverse crease lines break that the m+1 bar has n-1 break intersects m * n the isosceles trapezoid plane of reflection formation that forms, wherein:
Said n+1 bar longitudinal broken line be with wherein one for initial; Around its axis 00 ' rotation; Every rotation (180/n) ° obtains a longitudinal broken line, and the n+1 bar longitudinal broken line that obtains at last and the 1st longitudinal broken line are positioned at the same mounting plane through axis 00 ', and about axis 00 ' symmetry; All the other n-1 bar longitudinal broken lines are positioned at the same side of this mounting plane; The extended line of longitudinal broken line one end meets at the same point on the axis, the outside scattering of the other end, and the break on the same longitudinal broken line satisfies quadratic curve equation;
Said m+1 bar transverse crease lines is parallel each other;
Reflector is fixedly mounted on the led chip base through described mounting plane.
The area of m * n the plane of reflection that constitutes increases from inside to outside gradually.
The installation of reflector for ease, the present invention also is provided with an erecting bed on the said mounting plane of LED mine lamp with reflector, and erecting bed is provided with and is used for the LED mine lamp is fixed on the screw on the led chip base with reflector.
LED mine lamp provided by the present invention is merely about half of traditional mine lamp reflector with reflector; Be approximate half-circular; And the placement direction of led light source is also different with traditional LED mine lamp; The light source exiting surface direction of tradition LED mine lamp is consistent with the light direction of whole light fixture, and the light direction of the exiting surface direction of led light source and whole light fixture then is orthogonal among the present invention.LED mine lamp of the present invention has improved the illumination efficiency of LED mine lamp with this design of reflector, has promoted the light source utilization rate of mine lamp, has eliminated traditional mine lamp can form inhomogeneous hot spot in the field of illumination deficiency.
On the LED holder of miner's lampe, use above-mentioned reflector, the volume of LED holder of miner's lampe is much littler than traditional lamp holder, and the light fixture overall weight alleviates, and has so just alleviated workpeople's load, helps the operation of mine safety of workers more.
Description of drawings
Fig. 1 is the perspective view of the embodiment of the invention 1 said LED mine lamp with reflector;
Fig. 2 is the forward view of Fig. 1;
Fig. 3 is the A-A cutaway view of Fig. 2;
Fig. 4 is the perspective view of the embodiment of the invention 2 said LED mine lamps with reflector.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is done explanation further:
The LED mine lamp is with structure such as Fig. 1,2 and 3 of reflector 1, profile be approximately half bowl-shape.Its inner surface is the reflection of light face, and this reflecting surface is made up of m * n the isosceles trapezoid plane of reflection 4, and this m * n plane of reflection 4 is to have the longitudinal broken line 2 of m-1 break and crossing formation of transverse crease lines 3 breaks that the m+1 bar has n-1 break by the n+1 bar.
All n+1 bar longitudinal broken lines 2 have same axis 00 ', and the extended line of an end meets at the same public point place that is positioned on the axis 00 ', the outside scattering of the other end.All longitudinal broken lines 2 can be regarded as and ° obtained around the 00 ' rotation (180/n) of its axis by adjacent longitudinal broken line.And m+1 bar transverse crease lines 3 is parallel each other.Thus, the area of the m * n of a formation plane of reflection 4 increases from inside to outside gradually.
The LED mine lamp is identical with embodiment 1 with the structure of reflector 1, just on the mounting plane of reflector, adds an erecting bed 5, and erecting bed 5 is provided with screw, and the LED mine lamp is fixed on the led chip base through erecting bed 5 with reflector 1.
The height of erecting bed 5 can be adjusted according to the height of led chip, makes it reach the best light effect that goes out.
