Embodiment Construction

[0014] Such as figure 1 As shown, the street lamp of a preferred embodiment of the present invention includes a light pole 10 and a light emitting unit 50 installed on the light pole 10 .

[0015] The light pole 10 includes a main pole 12 and a pole 14 extending from the main pole 12 . Wherein the main rod 12 is hollow tubular, and a first channel 120 is formed in the main rod 12 . The main rod 12 is arranged vertically, and the bottom end of the main rod 12 is fixed on the ground. The top of the main rod 12 extends laterally outward to form a support rod 13 for installing the light-emitting unit 50 , and the end of the support rod 13 forms a plurality of through holes 130 , and the through holes 130 communicate with the first in the main rod 12 . The top of the channel 120 and the outside world.

[0016] Described strut 14 is connected on the main rod 12, and strut 14 is hollow tubular and open at both ends, and a second channel 140 is formed in this strut 14, and one end ...

Abstract

The invention provides a street lamp which comprises a lamp post and a light emitting unit arranged on the lamp post, wherein the lamp post comprises a main post and a branch post connected with the main post; the main post comprises a first passageway formed in the main post and a through hole arranged in the main post; a second passageway is formed in the branch post; the through hole is communicated with one end of the first passageway and the outside; the second passageway is communicated with the other end of the first passageway and the outside; the first passageway and the second passageway form an air flow path in the lamp post; and the light emitting unit is arranged on the main post and is located on the air flow path. In the invention, the air flow path communicated with the outside is formed in the lamp post; air in the lamp post is pushed to flow along the air flow path by dint of the fluctuation of a fluid, so that convection is formed in the lamp post, the emission of heat of a light emitting element is accelerated, the energy is saved, and the environment is protected.

Description

technical field [0001] The invention relates to a street lamp. Background technique [0002] Light-emitting diodes (LEDs) have the advantages of small size, high efficiency, no mercury, and long life, so they can replace existing fluorescent or incandescent lamps, reducing energy consumption and carbon dioxide emissions. However, the LED will generate a lot of heat when it is working, and poor heat dissipation will affect the luminous efficiency of the LED and even cause the LED to be damaged. Therefore, at present, the design is carried out around the heat dissipation of street lamps, including the design of heat sinks, the application of heat pipes, and the addition of fans to promote convection heat dissipation and so on. However, if a fan is to be added to achieve convection heat dissipation, it is necessary to supply power to the fan, which increases the loss of electric energy to a certain extent, and thus loses the meaning of energy saving.
