Description

Technical Field

[0001] The present invention relates to the technical field of street lamps, and more specifically, to an LED street lamp based on a high-efficiency heat dissipation lamp holder. Background Art

[0002] As energy resources become increasingly scarce and environmental awareness continues to increase, LED street lights are gradually replacing traditional lighting equipment due to their advantages of energy saving, environmental protection, and high efficiency. Various regions have promoted the application of LED street lights to achieve the goal of energy saving and emission reduction. LED street lights are widely used in various application scenarios and have become the mainstream product of modern urban lighting.

[0003] LED street lamps in the prior art may have a problem of insufficient heat dissipation in the lamp holder, which may cause the heat generated by the lamp holder to accumulate after long-term operation, causing the temperature to rise, which may cause the temperature of the lamp holder to exceed the working range, thereby damaging the lamp beads or other electronic components, shortening the service life and performance stability of the lamp holder. Insufficient heat dissipation may also cause problems such as lamp bead failure and reduced luminous flux, affecting the lighting effect and energy-saving performance. The lamp holders of some street lamps also have the problem of poor sealing. They are easily affected by moisture and water vapor intrusion in rainy weather. If the water vapor is not discharged in time, it is easy to cause circuit damage or short circuit.
