Description

LED street lamp lens cover
Technical field
The utility model belongs to technical field of semiconductor illumination, is specifically related to a kind of lens cover of the LED of being applicable to street lamp.
Background technology
Along with the fast development of semiconductor lighting technology, every technical parameters such as the light efficiency of LED light source, colour rendering index are significantly enhanced.LED, as a kind of new type light source of energy-conserving and environment-protective, has the advantages such as high light efficiency, long-life, low pressure, therefore is widely used in road lighting and room lighting field.For great power LED, be similar to spot light in the situation of far field, LED chip unit are luminous intensity is far above other conventional light source.Directly be applied in the illumination place if great power LED is not carried out to optical design, will produce dazzle, and on face to be illuminated, the gradient of Illumination Distribution be very large, do not meet hommization and the comfortableness requirement of illumination.
So, in LED street lamp R&D process, LED is carried out rationally to effectively secondary optical design and just is even more important.High-power LED street lamp has also adopted the free processing method by face lens or reflector, but the absorption of lens on light line, the very difficult utilization rate that improves light; Reflecting surface due to many reflectors is too single in addition, and the light fixture of designing can not reach the road lighting light distribution requirements.
Summary of the invention
The purpose of this utility model is to have overcome above-mentioned defect, provides a kind of luminous intensity distribution more reasonable, the LED street lamp lens cover that light loss is little and water resistance is good.
The utility model is achieved in that a kind of LED street lamp lens cover, and described LED street lamp lens cover front is provided with lens, the first protruding wall, and the described first protruding wall is arranged on lens periphery; The first chase and frame; Described LED street lamp lens cover bottom surface is provided with LED lamp chamber, circular groove, groove, the second protruding wall and the second chase; LED lamp chamber is for the installation of LED, and circular groove is taken a seat for the screw on fixing aluminium base, and groove is taken a seat for electric wire on aluminium base, and the second protruding wall is combined closely lens cover and aluminium base, and the second chase is used for installing sealing ring.
Further, described lens are the shelled peanut shape, have realized the two luminous intensity distributions such as degree such as grade of asymmetric batswing tab, and the road illumination uniformity, luminance uniformity are greatly improved.
Further, described lens are 6,8,18 or 24.
Further, in described the first chase, be provided with screwed hole, by screw fixed lens cover, and while using due to street lamp, the lens cover is down, and such the first chase just can, for screw provides waterproofing protection, prevent the screw corrosion.
Further, the height of the described first protruding wall and frame is consistent.
Further, four jiaos of described the first chase and frame are provided with reinforcement, avoid after long-term the use because warpage occurs material aging, cause sealing poor and seep water.
The beneficial effects of the utility model are: LED and lens combination all form an independently secondary optical system, increase the number of LED and lens, increased the light fixture luminous flux, hot spot and the uniformity are unaffected, otherwise too, even if damage when can not be normal shinny at certain LED, also just affect its illumination, and can not affect its uniformity; The overlapped addition of LED after array and lens combination (system) light, the rectangular light photograph spot that the length of side that still on road surface, forms an illumination that meets road safety and the uniformity is 1:4.The scioptics array, have a style of one's own, form cover, be applied in the LED street lamp light source module, with the lampshade integrated design, but the convenient dust-proofing waterproof makes the degree of protection of whole LED street lamp light source module self reach as high as IP67, the lens light extraction efficiency reaches more than 93%, compares with the street lamp that adds the light fixture face shield and reduces light loss 10%.
The accompanying drawing explanation

Fig. 2 is the schematic bottom view of the utility model LED street lamp cover.
Reference numeral: 1, lens; 2, the first protruding wall; 3, reinforcement; 4, the first chase; 5, screwed hole; 6, frame; 7, LED lamp chamber; 8, circular groove; 9, groove; 10, the second protruding wall; 11, the second chase.
The specific embodiment
Below in conjunction with Figure of description, the utility model is described in further detail.
Referring to Fig. 1 and Fig. 2, the utility model provides a kind of LED street lamp lens cover, and described LED street lamp lens cover front is provided with the protruding wall 2 of lens 1, first, and the described first protruding wall 2 is arranged on lens 1 periphery; The first chase 4 and frame 6; Described LED street lamp lens cover bottom surface is provided with LED lamp chamber 7, circular groove 8, the protruding wall 10 of groove 9, second and the second chase 11; LED lamp chamber 7 is for the installation of LED, and circular groove 8 is taken a seat for the screw on fixing aluminium base, and groove 9 is taken a seat for electric wire on aluminium base, and the second protruding wall 10 is combined closely lens cover and aluminium base, and the second chase 11 is for installing sealing ring.
Preferably, described lens 1 are the shelled peanut shape, have realized the two luminous intensity distributions such as degree such as grade of asymmetric batswing tab, and the road illumination uniformity, luminance uniformity are greatly improved.
