For realizing the requirement of road lighting to square type hot spot, must adopt lens to cut light to planar LED direct projection light source and process.It is fastening that existing LED lamp lens need to utilize a metal installation trim ring lens can be sealed when mounted, and quite trouble is installed.
The utility model content
The utility model provides a kind of LED street lamp distribution lens, and it has overcome the existing deficiency of background technology.The utility model solves the technical scheme that its technical problem adopts:
A kind of LED street lamp distribution lens, comprise convex cover section and the fixed part for being connected with lamp housing, this convex cover section comprises inner surface and outer surface, in on this inner surface, be concaved with for covering the accepting groove of LED light source, this fixed part is connected on the outward flange of this convex cover section, and this LED street lamp distribution lens is one-body molded.
Among one preferred embodiment: this LED street lamp distribution lens is by PC material integrated injection molding.
Among one preferred embodiment: this fixed part is provided with installing hole.
Among one preferred embodiment: this fixed part arranges around the whole circle outward flange of this convex cover section.
Among one preferred embodiment: on the inner surface of this fixed part, be concaved with for placing the groove of the first sealing ring, this groove is the circulus of head and the tail sealing.
Among one preferred embodiment: this fixed part has the interior surface of revolution, and the interior surface of revolution of the inner surface of this convex cover section and this fixed part surrounds for accommodating the storage tank of the second sealing ring.
Among one preferred embodiment: this accepting groove comprises two inclined top faces and two sides, and this two inclined top face intersects setting, and one of these two sides connect a side of this two inclined top face, and another of these two sides connects the opposite side of this two inclined top face.
Among one preferred embodiment: the angle between this two inclined top face is 100 degree-130 degree.
Among one preferred embodiment: the angle between this two inclined top face is 120 degree.
The technical program is compared with background technology, and it has following advantage:
1. this fixed part is connected on the outward flange of this convex cover section, again because this LED street lamp distribution lens is one-body molded, when mounted, directly this fixed part is connected to the installation that just can complete rapidly described lens on lamp housing, installs quite quick, convenient.
2. this LED street lamp distribution lens is by PC material integrated injection molding, and production efficiency is quite high, and these lens are lightweight.
3. this fixed part is provided with installing hole, utilizes bolt just these lens and lamp housing fast lock can be connected together.
4. this fixed part arranges around the whole circle outward flange of this convex cover section, is concaved with for placing the groove of the first sealing ring this lens good sealing effect on the inner surface of this fixed part.
5. the interior surface of revolution of the inner surface of this convex cover section and this fixed part surrounds for accommodating the storage tank of the second sealing ring, the dual waterproofing design of these lens, and sealing effectiveness is better.
6. this two inclined top face intersects setting, and the direct projection light that LED light source forms becomes rectangular light spot after described two oblique top minute surfaces refraction, thereby meets the road lighting requirement.
The accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 has illustrated the schematic perspective view of a kind of LED street lamp distribution lens of the utility model.
Fig. 2 has illustrated another schematic perspective view of a kind of LED street lamp distribution lens shown in Fig. 1.
Fig. 3 has illustrated the cross-sectional schematic of a kind of LED street lamp distribution lens shown in Fig. 1.
Fig. 4 has illustrated the cross-sectional schematic of another embodiment of a kind of LED street lamp distribution lens of the utility model.
The specific embodiment
Please refer to Fig. 1 to Fig. 3, a kind of LED street lamp distribution lens 100 of the present utility model, by PC material integrated injection molding.These lens 100 comprise convex cover section 10 1 fixed parts 20.
This convex cover section 10 comprises an inner surface 11 and an outer surface 12.This outer surface 12 is arc structure.Be concaved with an accepting groove 13 on this inner surface 11.This accepting groove 13 is for covering LED light source 200.This accepting groove 13 comprises two inclined top faces 131 and two sides 132.Setting is intersected on the top of this two inclined top face 131, and the angle β between this two inclined top face 131 is 100 degree-130 degree, preferably 120 degree.One of these two sides 132 connect a side of this two inclined top face 131, and another of these two sides 132 connects the opposite side of this two inclined top face 131.The bottom opening of this accepting groove 13 is rectangular.
This fixed part 20 is for linking together with lamp housing 300.This fixed part 20 is connected on the outward flange of this convex cover section 10, and this fixed part 20 arranges around the whole circle outward flange of this convex cover section 10.This fixed part 20 is provided with four installing holes 21.Described four installing holes 21 are intervally installed.Be concaved with the groove 22 for placing the first sealing ring 400 on the inner surface of this fixed part 20, this groove 22 is the circulus of head and the tail sealing.
Please refer to Fig. 4, it has illustrated the schematic diagram of the utility model the second embodiment.The difference of these lens 100a and the first embodiment is: this fixed part 20 has the interior surface of revolution 23, and the inner surface 11 of this convex cover section 10 surrounds the storage tank 30 for accommodating the second sealing ring 500 with the interior surface of revolution 23 of this fixed part 20.
By bolt 600 by these lens 100a together with the lamp housing interlocking, the inner surface 11 of these lens 100a is suppressed this first sealing ring 400, this second sealing ring 500 together with lamp housing.Due to the existence of this first sealing ring 400, this second sealing ring 500, form two dual waterproof sealing designs, sealing effectiveness is fairly good.
