Description

Solar street lamp Technical Field The utility model relates to the technical field of street lamps, in particular to a solar street lamp. Background The solar street lamp is used as an environment-friendly lighting device and is widely applied to urban roads, rural roads and various outdoor places. The solar street lamp converts solar energy into electric energy by using a solar panel, and stores the electric energy in a storage battery to provide electric power for illumination of the street lamp. Compared with the traditional city circuit lamp, the solar street lamp has the remarkable advantages of no need of laying cables, convenience in installation, low running cost, no pollution to the environment and the like. However, in the actual use process of the solar street lamp, the heat dissipation problem is gradually highlighted, and becomes a key factor affecting the performance and the service life of the solar street lamp. The illumination source of the street lamp, such as an LED lamp bead, generates a large amount of heat during operation. If this heat is not effectively dissipated in time, it will cause the light source to increase in temperature. The luminous efficiency of LED lamp pearl can be reduced to too high temperature, and light decay aggravates to influence the lighting effect and the life of street lamp. According to related researches, the luminous flux of the LED lamp beads can be reduced by about 3% -5% when the temperature of the LED lamp beads is increased by 10 ℃, and the LED lamp beads can be damaged after being in a high-temperature environment for a long time The utility model patent of China with the bulletin number of CN219473473U discloses a street lamp, which comprises a lamp post and a solar cell panel, wherein an installation rod is fixedly installed on the outer wall of the upper end of the lamp post, a lamp cap is fixedly installed at the left end of the installation rod, a heat dissipation mechanism is arranged at the upper end of the lamp cap, a lamp shade is fixedly installed at the lower end of the lamp cap, an installation seat is fixedly installed at the top end of the lamp post, and a connecting block is fixedly connected with the lower end of the solar cell panel. According to the street lamp, the heat absorbing plate is arranged on the lamp panel heating part of the lamp cap, heat generated by the lamp panel can be quickly absorbed, heat is dissipated through the heat dissipating aluminum fin edge part of the heat dissipating cavity part, meanwhile, the heat dissipating area of the heat dissipating aluminum fin is further enlarged by additionally arranging the heat dissipating grooves on the edge part of the heat dissipating aluminum fin, heat on the heat dissipating aluminum fin is conveniently transferred out through the heat dissipating holes in front of and behind the heat dissipating cavity, and therefore the heat dissipating effect inside the lamp cap can be greatly improved. However, in the practical use process, there are some disadvantages, for example, the heat dissipation holes are arranged to facilitate the heat generated by the lamp panel to be dissipated to the outside, but the outside water vapor also easily enters the lamp cap. Once moisture builds up in the lamp head, it can adhere to the surfaces of critical components such as the circuit board. The components in the lamp cap are in a moist environment for a long time, the insulating performance between the electronic components can be reduced by water vapor, and short-circuit faults are caused, so that the electronic components on the circuit board can be damaged, and safety accidents such as fire and the like can be even caused in serious cases. For this purpose, a solar street lamp is proposed.
