Embodiment 1

[0021] Such as figure 1 As shown, an anti-glare type high heat dissipation LED underground lamp includes an outer shell 1 and an inner shell 2, the inner shell 2 is provided with an LED lamp group 3, and the upper ends of the inner shell 2 and the outer shell 1 are both opened. , the inner shell 2 is arranged in an inverted circular truncated shape, a flexible annular plate 4 is arranged above the inner shell 2 and the outer shell 1, and the inner ring and outer ring of the flexible annular plate 4 are respectively fixed to the inner shell 2 and the outer shell 1 connection, the cross section of the flexible annular plate 4 is arranged in an upwardly arched convex shape, and a sealed cooling liquid cavity 5 is formed between the inner shell 2, the outer shell 1 and the flexible annular plate 4, and the cooling liquid cavity 5 is filled with cooling liquid. The coolant is water.

[0022] In this embodiment, two light-transmitting plates 6 are fixedly connected to the inner wal...

Embodiment 2

[0029] Such as Figure 2-3 As shown, the difference between this embodiment and Embodiment 1 is that two sliding plates 11 are slidably connected to the inner wall of the inner casing 2, and the LED lamp group 3 is fixedly installed on the upper surface of one of the sliding plates 11. The side walls of the block sliding plate 11 are respectively provided with matching protrusions 12 and grooves 13. The protrusions 12 are arranged in the grooves 13 and are slidably connected with the side walls of the grooves 13. The side wall of the groove 13 is fixedly connected, and the expansion bag 14 is filled with evaporating liquid, the evaporating liquid is acetone, and the boiling point is 56.2°C. The outer shell 1, the inner shell 2, and the sliding plate 11 are all made of metal materials, and the heat conduction effect is good. .

[0030] In this embodiment, when the LED lamp group 3 works for a long time, the temperature of the area where the LED lamp group 3 is located is relat...

Abstract

The invention belongs to the field of LED lamps, and in particular relates to an anti-glare type high heat dissipation LED underground lamp, comprising an outer shell and an inner shell, the inner shell is provided with an LED lamp group, the inner shell and the outer shell The upper ends are all open, the inner casing is set in an inverted circular truncated shape, and a flexible annular plate is arranged above the inner casing and the outer casing, and the inner ring and the outer ring of the flexible annular plate are respectively connected to the inner casing and the outer casing. The outer casing is fixedly connected, and the section of the flexible annular plate is arranged in an upwardly arched convex shape. A sealed cooling liquid cavity is formed between the inner casing, the outer casing and the flexible annular plate, and the cooling liquid cavity is filled with For cooling liquid, two light-transmitting plates are fixedly connected to the inner side wall of the inner casing, an opacifying agent is filled between the two light-transmitting plates, and a cooling liquid pipe is arranged between the two light-transmitting plates. The invention can lower the temperature of the sunscreen agent by stepping on the flexible annular plate by pedestrians, so as to play a light shielding effect, prevent glare from being generated, and affect the safe passage of pedestrians.

Description

technical field [0001] The invention belongs to the field of LED lamps, in particular to an anti-glare type high heat dissipation LED underground lamp. Background technique [0002] Buried lights, also known as Tibetan ground lights, are lighting facilities inlaid on the ground. Buried lights can illuminate the ground and vegetation on the ground, making the landscape more beautiful, adding beauty to the night scene of the city, and lighting pedestrians at the same time. , to ensure its safe passage. [0003] Most of the existing buried lights are buried in the road. The lights of the buried lights face up to illuminate the tree landscape above. When pedestrians walk above the buried lights, the light is likely to shine directly on the eyes of pedestrians, which is very dazzling. , especially LED underground lights, because LED lights have high orientation and strong light transmission, so the dazzling light at night can easily lead to temporary blindness of pedestrians and...
