Embodiment 1

[0021] like figure 1 As shown, an anti-glare type high heat dissipation LED underground lamp includes an outer casing 1 and an inner casing 2, the inner casing 2 is provided with an LED lamp group 3, and the upper ends of the inner casing 2 and the outer casing 1 are both open , the inner shell 2 is arranged in an inverted truncated cone shape, a flexible annular plate 4 is arranged above the inner shell 2 and the outer shell 1, and the inner and outer rings of the flexible annular plate 4 are respectively fixed with 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, 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 side wall of t...

Embodiment 2

[0029] like 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 side wall of the inner casing 2, and the LED light group 3 is fixedly installed on the upper surface of one of the sliding plates 11, and the two The side wall of the sliding plate 11 is respectively provided with a matching convex block 12 and a groove 13. The convex block 12 is arranged in the groove 13 and is slidably connected with the side wall of the groove 13. The side walls of the groove 13 are fixedly connected, the expansion bag 14 is filled with evaporating liquid, the evaporating liquid is acetone, and the boiling point is 56.2°C. .

[0030] In this embodiment, when the LED lamp group 3 works for a long time and the temperature of the area where the LED lamp group 3 is located is relatively high, the evaporation liquid in the expansion bag 14 evaporates and expands, and pushes the two sliding plates 11 away fro...

Abstract

The invention belongs to the field of LED lamps, in particular to an anti-dazzle high-heat-dissipation LED underground lamp. The anti-dazzle high-heat-dissipation LED underground lamp comprises an outer shell and an inner shell, an LED lamp set is arranged in the inner shell. The upper end of the inner shell and the upper end of the outer shell are both provided with openings. The inner shell is arranged in an inverted circular truncated cone shape; a flexible annular plate is arranged above the inner shell and the outer shell; an inner ring and an outer ring of the flexible annular plate arefixedly connected with the inner shell and the outer shell respectively; the cross section of the flexible annular plate is arranged in a convex surface shape which is arched upwards; a sealed coolingliquid cavity is formed among the inner shell, the outer shell and the flexible annular plate, the cooling liquid cavity is filled with cooling liquid, two light-transmitting plates are fixedly connected to the inner side wall of the inner shell, the space between the two light-transmitting plates is filled with opacifier, and a cooling liquid pipe is arranged between the two light-transmitting plates. Pedestrians can tread the flexible annular plate to cool the opacifying agent, so that the opacifying effect is achieved, and glare is prevented from being generated to affect safe passage of the 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 lights, are lighting facilities embedded on the ground. Buried lights can illuminate the ground and vegetation on the ground, which can make the landscape more beautiful, add beauty to the city's night scene, and illuminate pedestrians. , to ensure its safe passage. [0003] Most of the existing underground lights are buried in the road. The lights of the underground lights face upwards to illuminate the tree landscape above. When pedestrians walk above the underground lights, the lights are easy to directly hit the pedestrians' eyes, which is very dazzling. , especially the LED underground lights, because the LED lights have high directionality and strong light transmission, so the dazzling light at night can easily lead to short-term blindness of pedestrian...
