Abstract
The utility model discloses a radiator for an LED (Light Emitting Diode) streetlamp, which comprises a left wing, a right wing and a keel. A structure is arranged on the keel and is connected with a streetlamp supporting post; the left wing and the right wing are formed by extruding profiles, are respectively and detachably connected with the two sides of the keel, and are in flat shapes; the shapes of the left wing and the ring are in mirror symmetry; one face of each of the left wing and the right wing is used for installing a lamp body of the LED streetlamp; radiating fins are arranged on the other face of the left wing and the other face of the right wing; and the longitudinal cross sections of the radiating fins are in M shapes. With the adoption of the radiator, the processing difficulty and the processing cost can be reduced; and meanwhile, due to the M-shaped design, uniform radiating space of an LED is realized, so that local overheat of the LED is prevented, and the service life of the LED is further prolonged.
Description
Technical field
The utility model belongs to the radiator field, specifically is that a kind of LED street lamp is used radiator.
Background technology
The LED street lamp is energy-conserving and environment-protective product in the present illuminating product; But its led light source is because of having relatively high expectations to heat radiation; Especially the street lamp industry is carried out forced heat radiation because of fan can't be installed, and has influenced the service life of led light source greatly; This is the volume increase of heat radiation, has increased the difficulty and the manufacturing cost of extrudate.
Summary of the invention
In order to solve the problems referred to above that exist in the existing production technology, a kind of LED street lamp of utility model is used radiator, and concrete technical scheme is following:
A kind of LED street lamp is used radiator, comprises left and right both wings and keel three parts; Keel are provided with the structure that is connected with the street lamp support column; Left and right both wings are formed by the section bar extruding, and their shape becomes the mirror image symmetry, removably are connected the both sides of keel respectively; Said left and right both wings are flat patterns, and one side is used to install the lamp body of LED street lamp, and another side is provided with fin; The shape of the longitudinal cross-section of said radiator is a M shape.Such design can reduce difficulty of processing and processing cost; Simultaneously, because the design of M shape makes the heat-dissipating space of LED even, prevent the hot-spot of LED, and then prolong the service life of LED.
The radial section of said keel is annular; The inner edge of this ring section is circular, is used for being connected with the street lamp support column, and the outer rim of ring section is oval, and said left and right both wings promptly are connected both sides, oval-shaped major axis place.The cross sectional shape of said left and right both wings is semicircular arcs, and the thickness that is connected a side with keel is greater than be not connected a side with keel.When this design makes convenient the installation, increase the heat-conducting area of keel and both wings.The heat-conducting area of temperature higher position is strengthened, increase heat-conducting effect.Simultaneously, also strengthened the structural strength of junction.
Said left and right both wings be provided with and the corresponding cambered surface of keel left and right sides profile with links keel, the both sides up and down of cambered surface are provided with screw hole; On cambered surface, be provided with fin, keel are provided with corresponding groove, and fin embeds groove; The joint face of said left and right both wings and keel is provided with capillary groove, in capillary groove, is provided with the waterproof bar.This easy design installation, also guaranteed installation accuracy, the waterproof of junction has also been played good effect.
Said for the fin on the left and right both wings, be higher than the fin of opposite side near the fin of keel one side; The height of adjacent two fin is different, is provided with lower fin between the two higher fin.Such design helps the heat radiation of temperature higher position; The fin that height is provided with has also constituted the air channel of better effects if, simultaneously, has reduced difficulty of processing.
Said for the fin on the left and right both wings, be higher than the fin of opposite side near the fin of keel one side; The height of said adjacent two fin is different, is provided with lower fin between the two higher fin.
The total advantage of present technique scheme is that radiator area is big, and extruding is convenient in split, and overall weight is light, reduces cost.
Description of drawings
Fig. 1 is that the master of embodiment looks sketch map.
Fig. 2 is the schematic top plan view of embodiment.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment present technique scheme is further specified.
A kind of LED street lamp is used radiator, comprise left and right both wings 2 and 3 with keel 1; Keel 1 are provided with the structure 4 (hollow shown in Figure 1) that is connected with the street lamp support column; Left and right both wings 2 and 3 are formed by the section bar extruding, and their shape becomes the mirror image symmetry, removably are connected the both sides of keel 1 respectively; Said left and right both wings 2 and 3 are flat patterns, and one side is used to install the lamp body of LED street lamp, and another side is provided with fin 5; The shape of the longitudinal cross-section of said radiator is M shape, and is as shown in Figure 1.
The radial section of said keel 1 is annular; The inner edge of this ring section is circular, is used for being connected with the street lamp support column, and the outer rim of ring section is oval, and said left and right both wings 2 and 3 promptly are connected both sides, oval-shaped major axis place.
Said left and right both wings 2 and 3 cross sectional shape are semicircular arcs, and the thickness that is connected a side with keel 1 is greater than not being connected a side with keel 1.
Said for 2 and 3 fin on the left and right both wings, be higher than the fin of opposite side near the fin of keel one side; The height of said adjacent two fin is different, is provided with lower fin between the two higher fin.
In this example, left and right both wings be provided with and the corresponding cambered surface of keel left and right sides profile with links keel, the both sides up and down of cambered surface are provided with screw hole, with CARBURIZING FURNACE FOR STAINLESS FASTENER 8 left and right both wings being fixed on the keel 1.On cambered surface, be provided with fin 9, keel are provided with corresponding groove 10, and fin 9 embeds groove 10.Said left and right both wings 2 and 3 and the joint face of keel 1 be provided with capillary groove 6, in capillary groove, be provided with waterproof bar 7.
