[0002] Light-emitting diode lamps, also known as LED lamps, refer to devices that can transmit, distribute and change the light distribution of LED light sources. In addition to the LED light source, they include all parts and components required to fix and protect the LED light source, as well as the circuit accessories necessary for connecting to the power supply. With its technical characteristics of high efficiency, energy saving, safety, long life, compactness and clear light, light-emitting diode lamps are becoming the main products of the new generation of lighting market, and are effectively driving the rapid development of the environmental protection and energy-saving industry.

[0003] Based on the above, the inventors found that the following problems exist: at present, LED lamps are also installed in the park for lighting, and protective covers are installed on the top or outside of the lamps to protect the lamps, but the protective covers on the lamps cannot be adjusted. Generally, the LED lamps in the park are on from dusk to late at night. In the evening, the lamps are turned on. If a protective cover is installed on the outside, the lighting may not be good enough. If a lampshade is not installed on the outside, after the lamp light continues until late at night, the contrast between the brightness of the lamp and the external darkness will appear more dazzling. When the lamps are installed on the roadside, when people gradually approach the lamps, they cannot see the lower road surface clearly, which will affect the line of sight of night runners and has certain usage limitations.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a LED lamp for park use is provided, in order to achieve the purpose of having more practical value. Utility Model Content
