Embodiment

[0026] Such as figure 1 As shown, a solar-powered LED landscape light includes an LED light source 1, a control board 5, and a support cover 2. A solar panel 3 is arranged on the top of the support cover 2, and the solar panel 3 and the control panel 5 input The LED light source 1 is connected to the output end of the control board 5 through a line, and the back of the LED light source 1 is fixedly connected with a heat dissipation base plate 4 . Such as figure 2 As shown, the heat dissipation bottom plate 4 is closed on all sides and has a hollow structure 6 in the middle. The heat dissipation bottom plate 4 is provided with several upright blades 7 , and intervals are formed between the blades 7 . The heat dissipation bottom plate 4 of the above structure reduces the area occupied by the heat dissipation bottom plate 4 by increasing the volume of the heat dissipation bottom plate, which will reduce the heat radiated from the heat dissipation bottom plate 4 to the LED light...

Abstract

The invention discloses a solar power supply based LED (Light Emitting Diode) landscape lamp, which comprises an LED light source, a control panel and a support cover body. The support cover body is provided with a solar battery plate at the top end. The solar battery plate is connected with the input end of a control plate. The LED light source is connected with the output end of the control plate. A radiating bottom plate is fixedly connected to the back of the LED light source. The radiating bottom plate is sealed around and the middle part of the radiating bottom plate adopts a hollow structure. The radiating bottom plate is provided with a plurality of vertical vanes, between which gaps are formed. Heat exchange outward is effectively carried out by the radiating bottom plate through heat radiation exchange. Meanwhile, air at the hollow structure is subjected to disturbance to form good heat convection rising power, so that heat flows upward quickly through a hollow area well, thereby effectively preventing the LED light source from being damaged due to overheat of the LED landscape lamp, and prolonging the service life of the LED.

Description

technical field [0001] The invention relates to the technical field of landscape lighting, in particular to an LED landscape light powered by solar energy. Background technique [0002] With the improvement of people's living standards, the pursuit of spiritual civilization is also getting higher and higher. Residents living in cities and counties, towns and villages with better living conditions, when night falls, can enjoy the scenery in tourist attractions, parks, squares, private gardens, rivers and rivers. Landscape lights of various colors are added to one side of the road in public places such as sides, courtyard corridors, etc., to increase the time for people to travel at night or outdoor activities, and can improve the safety of travel and change people's mood. When the festival comes, it can also enhance the festive atmosphere. [0003] At present, most landscape lights use LEDs as light sources. LEDs have a long service life, which can reach more than 100,000 hou...
