Abstract
The utility model relates to the field of luminaries, in particular to a lower bend-typed lamp arm of an LED street lamp, which consists of the lamp arm which is arranged on a column. The lamp arm is lower bend-shaped, the bottom side of which is provided with a plurality of concave ventilation openings, the lamp cap adopts a seamless top shell and forms a communicated body with the lamp arm, the luminous surface component of the LED street lamp and the circuit are sealed, and the luminous surface component is connected with the top shell of the lamp cap by a cooling fin group with a larger gap; and hot air is produced from the cooling fin below the top shell of the lamp cap, flows through the inside of the lamp arm and forms convection with cold and hot air in the ventilation openings. As the top shell is enclosed, the luminous surface component and the circuit are sealed and the cooling fin is of vertical structure, dust is difficult to stay at the cooling fin, and water vapor is easy to guide away. By adopting the simple structure of the lamp arm, the cold and hot air are convective, and dust and water can be prevented, thus increasing the stability of the street lamp and reducing the production cost of the heat radiating device and the lamp shell at the same time.
Description
Technical field
The utility model relates to field of light fittings, is specifically related to curved formula arm under a kind of LED street lamp.
Background technology
Along with the social trend of energy-saving and emission-reduction, the LED street lamp will day by day replace conventional road lamp at aspects such as luminous efficiency, energy-saving and environmental protection, and the problem of LED street lamp maximum is that heat dissipation capacity is big at present, and can only be by the heat conduction; The bright temperature of LED street lamp surpasses 60 degrees centigrade of light efficiencies and promptly begins to descend.Be outdoor installation for street lamp in addition, water proof and dust proof also is the problem that the design of LED street lamp faces.Can't solve heat radiation effectively, then can quicken the aging of LED light fixture greatly, cause its light efficiency to reduce.Sticking of dust, make radiator can't reach the heat radiation requirement of LED street lamp with reducing the usefulness of radiating element.Present LED street lamp adopts semiclosed lamp housing to add fin, heat pipe pattern, can't satisfy heat radiation and dustproof requirement.
Summary of the invention
In order to solve heat dissipation problem, and make the LED street lamp satisfy the water proof and dust proof requirement, the utility model provides a kind of curved formula arm down, be beneficial to cold-hot air convection, by cold-hot air convection, can effectively lead away the heat of radiator, and avoid the influence of dust and steam radiator.
The technical scheme that its technical problem that solves the utility model adopts is: curved formula arm under a kind of LED street lamp, constitute by the arm that is installed on the column, described arm is curved formula shape down, described arm bottom side is provided with a plurality of matrix ventilating openings, lamp holder adopts seamless top shell and forms connected component with arm, the light-emitting area parts of described LED street lamp and circuit are sealing, described light-emitting area parts are connected with lamp holder top shell by the groups of fins that big gap is arranged, hot-air produces from the fin under the shell of lamp holder top, flow by arm inside, and carry out convection current with the cold and hot air of ventilating opening.
Because adopt that the top shell is airtight, light-emitting area parts and circuit sealing, structure that fin is vertical, dust is difficult to reside on the fin, steam also is easy to lead away, make cold-hot air convection by the simple structure of arm, and dustproof and waterproof, when having improved street lamp stability, reduced the production cost of heat abstractor and lamp housing.

Fig. 1 is the structural representation of curved formula arm under a kind of LED street lamp of the utility model.
Fig. 2 is the upward view of Fig. 1.
Fig. 3 is the cold-hot air convection schematic diagram of curved formula arm under a kind of LED street lamp of the utility model.
Fig. 4 is the three-dimensional cross section explosion views of curved formula arm under a kind of LED street lamp of the utility model.
The specific embodiment
As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, curved formula arm under a kind of LED street lamp, constitute by the arm 1 that is installed on the column 3, described arm 1 is curved formula shape down, described arm 1 bottom side is provided with a plurality of matrix ventilating openings 11, lamp holder adopts seamless top shell 2 and forms connected component with arm 1, the light-emitting area parts of described LED street lamp and circuit are sealing, 21 groups of the fin of described light-emitting area parts by big gap is arranged are connected with lamp holder top shell 2, hot-air produces from the fin 21 under the lamp holder top shell 2, flow by arm 1 inside, and carry out convection current with the cold and hot air of ventilating opening 11.Because adopt that the top shell is airtight, light-emitting area parts and circuit sealing, structure that fin is vertical, dust is difficult to reside on the fin, steam also is easy to lead away, make cold-hot air convection by the simple structure of arm, and dustproof and waterproof, when having improved street lamp stability, reduced the production cost of heat abstractor and lamp housing.
