Energy-saving power-generation street lamp with adjustable illumination angle

Abstract

An energy-saving power-generation street lamp with an adjustable illumination angle comprises a lamp pole fixedly arranged on a base. The upper portion of the lamp post is fixedly connected with a connecting rod, the other end of the connecting rod is fixedly connected with a lamp holder which comprises a shell, the shell is composed of a cuboid portion and a hemisphere portion which are separatedthrough an intercepting net, a support is arranged inside the cuboid portion, a plurality of LED lamps are arranged on the lower side of the support, and the upper side of the support is fixedly connected with a cooling fin; a ventilation hole is formed in the side wall of the top of the hemisphere portion, and a hinge is arranged at the top of the hemisphere portion. The energy-saving power-generation street lamp has the advantages that the LED lamps can generate a lot of heat during working, service life of the LED lamps can be affected if the heat cannot be timely dissipated, and the cooling fin is utilized to transmit the heat out to realize good cooling effect; the arc-shaped fin enables contact area of the cooling fin and air to be greater, so that cooling effect is improved further.

Description

technical field [0001] The invention relates to an illuminating street lamp, in particular to an energy-saving power-generating circuit lamp with the function of adjusting the illumination angle. Background technique [0002] Street lamps refer to lamps that provide lighting functions for roads, and generally refer to lamps within the range of road lighting in traffic lighting. The words of Xia Zhixu's "Pieces of Memories": "Pedestrians are scarce, and street lights are dim." my country's street lamp construction has achieved rapid development, the quality of road lighting has been continuously improved, and high-intensity gas discharge lamps are widely used. The investment environment, the promotion of rapid economic development, the convenience of people's life, the beautification of the city and the construction of an export-oriented modern city have played a big role. 1. According to the height of the street lights: high pole street lights, middle pole lights, road light...

AI Technical Summary

Problems solved by technology

[0008] LED lights will generate a lot of heat during the process of lighting. If the heat cannot be dissipated in time, the service life of the LED lights will be affected. When there are cooling holes, rainwater will drip from the cooling holes and affect the interior of the lamps; and If there is no light in rainy and snowy weather, street lights will not work, and municipal power is still needed for auxiliary lighting, which causes great inconvenience in use
