Further the starting point of the side camber line of reflector apart from light source center point apart from k=50mm, reflector height y=76mm～82mm.
Above-mentioned led light source emits beam behind said reflector secondary light-distribution, and beam angle is 70 °～76 °.
The utility model reflector also has following advantage:
1, low-angle industrial lighting lamp reflector can satisfy one times of lamp installation with interior during apart from height ratio, and uniformity of illuminance satisfies the architectural lighting design standard more than 0.9 fully in the operating area;
2, because there is aberration in led light source, so in irradiation area, there is aberration, led light source makes led light source emergent ray mixed light behind low-angle industrial lighting lamp reflector luminous intensity distribution, eliminate the aberration phenomenon in the irradiation area.
3, because the brightness value size of any and light source square being inversely proportional to that emit beam on the receiving plane to the distance of changing the time; So light fixture that tradition does not design through luminous intensity distribution; A part of light does not shine on the working face or shines the hypertelorism on the working face in the light source emergent ray, and the efficiency of light energy utilization is low.Led light source is behind low-angle industrial lighting lamp reflector luminous intensity distribution, and emergent ray is radiated in the working region through beeline, promotes the efficiency of light energy utilization.
4, through changing the pip of article one emergent ray, can change low-angle industrial lighting lamp reflector side camber line equation, thereby produce the reflector that satisfies Different Light size luminous intensity distribution.
The utility model helpfulness; The utility model adopts the low-angle industrial lighting lamp reflector of above-mentioned side camber line cubic equation design; Solved the deficiency that above-mentioned LED industrial lighting lamp reflector exists, the light angle of the utility model low-angle industrial lighting lamp reflector is 72 °, has improved the illumination efficiency of industrial lighting lamp; Satisfy lamp installation apart from high uniformity requirement when; Promote the light source utilization rate, in one times of height ratio, eliminated existing LED industrial lighting lamp can form inhomogeneous hot spot in the field of illumination deficiency in lamp installation.
