Description
Technical field
The utility model relates to a kind of reflector of light fixture, particularly relates 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 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 color spot can occur in irradiation area, influences normal operation.
Simultaneously, new mine lamp national standard promotion and implementation require the irradiating angle of mine lamp to satisfy in the new standard: last 30 °, following 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 utility model provides a kind of LED mine lamp reflector, and present mine lamp light extraction efficiency is low to solve, there is color spot in irradiation area, and the shortcoming of the not enough standard of rising angle.
In order to solve above technical deficiency, the utility model 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 made up of first reflecting surface and second reflecting surface, and second reflecting surface is connected on the outward flange of first reflecting surface;
Described 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 with wherein one for 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 m * n the plane of reflection that constitutes increases from inside to outside gradually.
Described second reflecting surface is connected to form by the identical semi-cylindrical that one deck at least is arranged in together.
Usually, second reflecting surface is made up 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.
The installation of reflector for convenience, the utility model also is provided with an erecting bed on the described mounting plane of LED mine lamp reflector, and erecting bed is provided with and is used for the LED mine lamp reflector is fixed on screw on the led chip base.
The LED mine lamp reflector that the utility model provides only is about half of traditional mine lamp 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 exiting surface direction of led light source then is vertical mutually with the light direction of whole light fixture in the utility model.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 utility model increases this particular edge design of second reflecting surface on the LED mine lamp reflector, make and 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 on 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, helps the operation of mine safety of workers more.
