DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1-4, a non-isolated power supply-based lightweight and high luminous efficiency LED street lamp, comprising a lamp body. The lamp body includes a support frame 1, a bottom frame 2, a controller 3, a surge protector 4, a top frame 5 and a lamp board 6. One end of the bottom frame 2 is connected to the support frame 1, and the other end of the bottom frame 2 is embedded with the lamp board 6. The lamp board 6 is arranged on the top frame 5 of the bottom frame 2. The bottom frame 2 is also provided with a controller 3 connected to the lamp board 6 and the surge protector 4. The controller 3 is arranged between the support frame 1 and the top frame 5. The top frame 5 is also provided with an auxiliary board 7 for carrying the controller 3 and the surge protector 4. The auxiliary board 7 is arranged between the support frame 1 and the top frame 5.

[0025] During actual use, the support frame 1 provides stable support for the bottom frame 2. The controller 3 and the surge protector 4 are assembled on the auxiliary board 7 above the bottom frame 2. The input 100 - 277V front end is built-in with a 20KV surge protector 4 to ensure that the lamp can be used sustainably, stably and safely in a harsh environment. Below the top frame 5 of the bottom frame 2, there is a lamp board 6, and several groups of uniformly arranged LED light sources 8 are arranged on the lamp board 6 to ensure the uniformity of light output. Below the lamp board 6, there are several groups of light-transmitting covers 9 covering the LED light sources 8. The light-transmitting covers 9 ensure the softness of light output, prevent the light from affecting people's line of sight and are convenient to use. The polycrystalline LED light sources 8 have high luminous efficiency, and the overall luminous efficiency of the lamp reaches 212.05 lm / w.

[0026] In this embodiment, a reflective film 10 is also arranged below the lamp board 6. The LED light sources 8 are arranged on the periphery of the reflective film 10. Using a PC ultra-high reflection nano material, the reflected light of the lens is reused, greatly improving the luminous efficiency.

[0027] To facilitate the maintenance and inspection of the equipment, a hinge seat 11 is arranged on the top frame 5. One end of the auxiliary board 7 close to the top frame 5 is provided with a hinge shaft connected to the hinge seat 11, and the other end of the auxiliary board 7 is clamped with the bottom frame 2, so as to ensure that it is convenient to open the auxiliary board 7 for the maintenance and inspection of the controller 3 and other components.

[0028] In this embodiment, a grille 14 is also arranged below the top frame 5, increasing the heat dissipation area, enhancing the ability of the light source to conduct heat outward, improving the luminous efficiency and service life, and using a magnesium alloy lightweight and high-hardness material to ensure a relatively high cost performance of the lamp.

[0029] To further provide good protection for the lamp board 6, a protection board 12 for covering the lamp board 6 and the light-transmitting cover 9 is arranged on the bottom frame 2. The protection board 12 is connected to the bottom frame 2 through bolts 13, which is convenient for disassembly and assembly.
