Problems solved by technology
[0005] Generally speaking, the existing solar LED street lamps directly install the radiator on the lamp housing for heat dissipation, but with the continuous improvement of photoelectric conversion efficiency, the power of solar street lamps is getting larger and larger, and the existing LED heat dissipation methods are due to heat dissipation. The limited area obviously cannot meet the heat dissipation needs of high-power LEDs
In addition, the current domestic LED heat dissipation technology mainly starts with improving the LED luminous efficiency and improving the heat dissipation capacity of the device. These technologies can effectively reduce the temperature of the LED chip, but it is not easy to improve the heat dissipation function on the basis of the chip. It is even more difficult, especially under the premise that there is no independent research and development of LED chips in China

Embodiment
[0023] Such as Figure 1 to Figure 3 As shown, a solar LED street lamp with a new heat dissipation device includes a radiator 1, a solar panel 4 for converting solar energy into electrical energy, an LED lamp 3 connected to the solar panel 4, and a heat pipe 2; wherein The radiator 1 is arranged under the solar panel 4, and the radiator 1 and the LED lamp 3 are connected through the heat pipe 2. The heat pipe 2 is a hollow structure, which can dissipate the heat generated by the LED lamp 3. The heat is transferred to the radiator 1, and then the heat is quickly dissipated by the radiator 1.
[0024] As a partial preferred solution of the above-mentioned embodiment, the radiator 1 includes a plurality of cooling fins 101 arranged in an array, and the cooling fins 101 are respectively connected to the solar cell panels 4, and the arrayed cooling fins 101 have extremely high cooling efficiency.

The invention relates to a solar LED street lamp with a novel radiating device. The solar LED street lamp comprises a radiator, a solar panel, an LED lamp and a heat conduction tube. The radiator is arranged at the lower portion of the solar panel and connected with the LED lamp through the heat conduction tube. According to the solar LED street lamp, the radiating technology of the heat conduction tube is adopted, heat generated by the LED lamp is transmitted to the radiator arranged at the lower portion of the solar panel, radiating efficiency is improved, the service life of the LED lamp is prolonged, and meanwhile pressure of a cantilever is reduced. In addition, due to the fact that the radiator is separated from the LED lamp, the sealed lamp can be designed, and the phenomenon that a circuit inside the lamp is damaged when ants, moths, ash zones and the like fall into the lamp body is avoided.
Description
technical field [0001] The invention relates to an LED lamp, in particular to a solar LED street lamp with a novel cooling device. Background technique [0002] As a green and environmentally friendly new energy source, solar energy is "inexhaustible and inexhaustible". Against the backdrop of increasing global energy shortage and environmental pollution, solar energy, as a sustainable and clean energy source, has attracted great attention from all quarters. [0003] LED or light-emitting diode has the characteristics of high efficiency, safety, energy saving, environmental protection and long life. It is precisely because of these advantages that more and more people choose LED as the light source in the field of lighting. With the implementation of my country's energy-saving emission reduction policy, green lighting has been included in key energy-saving projects. [0004] Although the luminous efficiency of the LED is high in theory, in fact, 80% of the electric energy...
