Description
Technical field
The present invention relates to a kind of reflector of light fixture, particularly relate to a kind of LED mine lamp reflector.
Background technology
Mine lamp is the lighting apparatus of mine workman indispensability.The tradition mine lamp adopts bilux bulb as lighting source, and not only power consumption is large, and bulb excess Temperature when using, and has potential safety hazard.
LED (light emitting diode) has the 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, the 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 color spot can occur in irradiation area, affects normal operation.
Simultaneously, new promotion and implementation of mine lamp national standard require the irradiating angle of mine lamp to satisfy in the new standard: upper 30 °, lower 60 °, about each 45 °.And the irradiating angle of traditional mine lamp has no longer met above-mentioned standard-required.
Summary of the invention
The purpose of this invention is to provide a kind of LED mine lamp reflector, present mine lamp light extraction efficiency is low to solve, there is color spot in irradiation area, and the shortcoming of the inadequate standard of rising angle.
In order to solve above technical deficiency, the present invention adopts following technical scheme:
A kind of LED mine lamp reflector is fixedly mounted on the led chip base, is used for led chip and goes out reflection of light, and its inner surface is comprised of the first reflecting surface and the second reflecting surface, and the second reflecting surface is connected on the outward flange of the first reflecting surface;
Described the first reflecting surface is to have the longitudinal broken line of m-1 break 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 by the n+1 bar, wherein:
Described n+1 bar longitudinal broken line be take wherein one as initial, around its axis 00 ' rotation, every rotation (180/n) ° obtains a longitudinal broken line, the n+1 bar longitudinal broken line that obtains at last and the 1st longitudinal broken line are positioned at the same mounting plane by 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, the break on the same longitudinal broken line satisfies quadratic curve equation;
Described m+1 bar transverse crease lines is parallel each other;
The area of described m * n plane of reflection increases from inside to outside gradually.
Described the second reflecting surface is connected to form by one deck identical semi-cylindrical arranged together at least.
Usually, the second reflecting surface is comprised of 3 layers of continuous semi-cylindrical stack at least, and every layer semi-cylindrical area increases from bottom to top gradually.
Reflector is fixedly mounted on the led chip base by described mounting plane.
In order to make things convenient for the installation of reflector, the present invention also is provided with an erecting bed on the described mounting plane of LED mine lamp reflector, and erecting bed is provided with for the screw that the LED mine lamp reflector is fixed on the led chip base.
LED mine lamp reflector provided by the present invention only is about half of traditional mine lamp reflector, be approximate half-circular, and the placement direction of led light source is also different from 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 exiting surface direction of led light source then is mutually vertical with the light direction of whole light fixture among the present invention.This design has improved the illumination efficiency of LED mine lamp, 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.
Simultaneously, the present invention increases this particular edge design of the second reflecting surface at the LED mine lamp reflector, so that can further spread emergent light, has guaranteed that the light angle of LED mine lamp meets current national mine lamp illumination new standard.
Use above-mentioned reflector at the LED holder of miner's lampe, the volume of LED holder of miner's lampe is more much smaller than traditional lamp holder, and the light fixture overall weight alleviates, and has so just alleviated workpeople's load, more is conducive to the operation of mine safety of workers.
