Problems solved by technology

The heat dissipation of LED lights is generally to add an alloy heat sink with good thermal conductivity on the back of the substrate of the LED street lamp. Due to the limited surface area of ​​the heat sink, the heat dissipation effect is not ideal, especially after the heat sink is covered by dust, the temperature of the substrate of the LED street lamp is 140 degrees. , which seriously affects the lighting effect and life of LED street lamps

Embodiment 1

[0027] like figure 1 As shown, a solar photosensitive street lamp with a thermosiphon cooling system includes a light pole 1 and a circuit-connected LED lamp assembly 4 , a switch assembly, a photosensitive assembly 8 , a solar panel 7 , a controller 5 , and a lithium battery assembly 6 . The street lamp also includes a thermosiphon cooling system for cooling the LED lamp assembly 4 , the controller 5 , the solar panel 7 , and the lithium battery assembly 6 . like figure 2 As shown, the thermosiphon cooling system includes cooling liquid and a set of cooling liquid sealed pipes 11 for the cooling liquid to circulate back and forth. The coolant sealed pipeline 11 passes through the LED lamp assembly 4 , the controller 5 , the solar panel 7 , and the lithium battery assembly 6 to form a closed loop. A coolant storage tank 10 communicated with the coolant seal pipeline 11 is provided on the coolant seal pipeline 11, and a liquid inlet communicated with the coolant seal pipelin...

Embodiment 2

[0036] This embodiment is improved on the basis of Embodiment 1. The improvement is that: the switch assembly includes a light-activated switch and a voice-activated switch controlled by time intervals, which can be adjusted according to the intensity of the current light received by the light-sensing assembly 8 during the day. Weak control LED light switch. At night, according to the current time period, the light control switch or the voice control switch is used to control the switch of the LED light. For example, according to the number of pedestrians and vehicles on the road where the street light is installed, the controller 5 is set to the light control switch to control the switch of the LED light before 12 o'clock. After clicking, the voice-activated switch controls the LED light switch, so that the street lights can reduce the lighting time in the middle of the night when there are few pedestrians and vehicles, save electricity, and prolong the time that the solar str...

Description

technical field [0001] The invention relates to the technical field of solar street lamps, in particular to a solar photosensitive street lamp with a thermosiphon cooling system. Background technique [0002] Solar street lights are powered by crystalline silicon solar cells, maintenance-free valve-regulated sealed batteries (colloidal batteries) store electrical energy, LED lamps are used as light sources, and are controlled by intelligent charge and discharge controllers. They are energy-saving street lights that replace traditional public electric lighting. Solar street lights do not need to lay cables, do not need AC power supply, and do not generate electricity bills; solar street lights save worry and trouble, and can save a lot of manpower and energy. Solar street lights adopt DC power supply and photosensitive control; they have the advantages of good stability, long life, high luminous efficiency, easy installation and maintenance, high safety performance, energy sa...
