Detailed description of the invention
Fig. 1 is the structural schematic diagram of lampshade
Fig. 2 is the diagrammatic cross-section of structure
Fig. 3 is the enlarged diagram of section middle section
Fig. 4 is the enlarged diagram of sides section view part
Fig. 5 is traditional Tri-proof light distribution curve flux
Fig. 6,7,8 are the typical Tri-proof light distribution curve fluxs that can be realized by design
Specific embodiment:
Fig. 1 show a kind of LED Tri-proof light lampshade, connects including the canopy main body and canopy main body that link together and lampshade Socket part, lampshade in being located at the upper surface of lampshade interconnecting piece, canopy main body outer surface, that is, the slight frosted of outer wall, primarily to Prevent lamps and lanterns light leakage, caused by dazzle the eyes sense;Canopy main body inner surface, that is, the densely covered prism structure of inner surface.
Lampshade is divided into straight line portion 11 and annular section 12, and straight line portion is consistent with the profile of annular section, annular section It is that straight parts extend.Straight line portion 11 is the main part for realizing light distribution optical effect, and annular section 1 plays appearance.
Fig. 2 is the profile of lampshade, and the profile is usually axisymmetric, mainly meets symmetrical optical effect needs, non-axis Symmetrical profile also in rights protection, mainly meets asymmetrical optical demands, LED light source 13 is located among lamps and lanterns.Pass through The design of prism is so that light changes in one direction, so that distribution curve flux is made to change, the length direction of the lamps and lanterns For Lambertian light distribution, the width direction abnormal shape light distribution (0 ° of non-maximum of direction light intensity) of the lamps and lanterns.
The light distribution of traditional Tri-proof light is generally approximate Lambertian type, and 0 ° of direction light intensity is maximum, to realize uniformity, is bound to Need to reduce the central light strength in 0 ° of direction, the prism of lampshade interior surface is mainly formed by two kinds, and middle section 14 is recess Prism, from LED light source 13 by diverging prism, light will do it diverging, by adjusting the angle [alpha] (α of different location prism It is the angle of prism Yu lamps and lanterns contoured surface), when α angle is bigger, divergence of beam degree is higher, realizes the promotion of uniformity, 0 ° of side Reduction to light intensity.
The light distribution of traditional Tri-proof light is generally approximate Lambertian type, the direction greater than 70 ° there are also a large amount of light loss, these The UGR of lamps and lanterns can be made to increase, so to improve uniformity, reducing UGR just must be curved to low-angle direction by the light of wide-angle Folding.The prism of lampshade interior surface is mainly formed by two kinds, and lateral section 15 is the prism of protrusion, the main foldover of this part lens Light action says that the high angle scattered light that LED is issued becomes the lesser light of angle by prism, rises and promotes capacity usage ratio, uniformly Property and reduce the effect of system UGR on one side 151 to meet processing draft needs, it is vertical to need to be arranged near normal, another side 152 main optical effects, by adjusting the angle beta of different location side prism, (β is the folder of prism Yu lamps and lanterns contoured surface Angle), the light bending of different angle may be implemented.
The limitation of the typically no size of the design method of the prism, but for the reduction of processing cost, each prism Generally less than 2mm.
It should be understood that being the method for the light distribution realized on Tri-proof light lamps and lanterns by prism above.As long as application should Method realizes different light distribution forms, and the light intensity value for referring specifically to 0 ° of direction is less than special angle, according to requiring special angle Reach light intensity maximum value, from 15 ° -75 °, is likely to.Within the spirit and principles in the present invention, can add according to the above description
With increase and decrease, replacement, transformation or improvement, and all these increases and decreases, replacement, transformation or improved technical solution, should all it belong to In the protection scope of appended claims of the present invention.
