Problems solved by technology

[0003] When the lawn lamp is used, the heat generated by the light source needs to be well dissipated to make the lawn lamp have a longer service life. The heat sink in the existing lamps is plate-shaped or sheet-shaped. The ventilation of the heat sink The performance is relatively insufficient, which affects the heat dissipation of the heat sink

Embodiment 1

[0018] A kind of vertical lawn lamp, comprises lamp tube, tube cover 1, light-transmitting cover 2, LED light source assembly 3, radiator plate 4, as figure 1 with image 3 , the light transmission cover 2 is a cylindrical light transmission cover 2 made of transparent resin, the light transmission cover 2 is covered on the heat dissipation plate 4, the light transmission cover 2 and the heat dissipation plate 4 form a light source room, and the light source room is equipped with LED light source components 3. The LED light source assembly 3 includes a substrate and a number of LED light sources fixed on the substrate. The substrate is fixed on one side of the heat dissipation plate 4. The other side of the heat dissipation plate 4 is welded with a heat dissipation burr 5. The heat dissipation burr 5 is tapered, and the heat dissipation burr 5 The cross-sectional diameter gradually decreases from the welding end to the other end. The heat dissipation plate 4 is cylindrical. Th...

Embodiment 2

[0021] Embodiment 2 is basically the same structure as Embodiment 1, the difference is that the lamp tube includes an upper cylinder body 9 and a lower cylinder body 10, the upper cylinder body 9 is connected to the cylinder cover 1, the lower cylinder body 10 is sealed and connected to the cylinder seat 11, and the light-transmitting cover 2. The LED light source assembly 3 and the heat dissipation plate 4 are arranged between the upper cylinder 9 and the lower cylinder 10 , and the lower cylinder 10 is provided with a plurality of vents 12 communicating with the heat dissipation channels 6 . A heat dissipation umbrella group 8 is arranged between the adjacent heat dissipation burrs 5, and the heat dissipation umbrella group 8 is composed of several umbrella-shaped heat dissipation units connected in sequence.

[0022] The heat dissipation umbrella group 8 in the second embodiment greatly increases the heat dissipation area, and the heat dissipation effect is better. ...

Abstract

The invention provides a vertical lawn lamp which comprises a lamp drum, a drum cover, a light-permeable cover, an LED light source component and a radiating plate. The light-permeable cover is a drum-shaped light-permeable cover made of transparent resin. The light-permeable cover covers the radiating plate. The light-permeable cover and the radiating plate form a light source chamber. The LED light source component is disposed in the light source chamber. Conical radiating burrs are welded on the other side of the drum-shaped radiating plate. The radiating plate is connected to the lamp drum in a sealed manner. A radiating passage is formed at the central axis of the lamp drum. The lower end of the lamp drum is connected to a drum base. The drum cover is disposed at the top end of the lamp drum. An upper air passing opening is formed between the drum cover and the lamp drum. A lower air passing opening is formed between the drum seat and the lamp drum. The upper air passing opening and the lower air passing opening are communicated with the radiating passage. Due to the fact that the conical radiating burrs are disposed in the lamp drum, radiating area is increased while ventilation performance of the radiating plate is increased, radiating effect is increased, and the radiating burrs can be prevented from being deformed, damaged and the like by external force.

Description

technical field [0001] The invention relates to a vertical lawn lamp. Background technique [0002] Lawn lights are widely used in urban slow lanes, narrow lanes, residential areas, tourist attractions, parks, squares, private gardens, courtyard corridors and other public places on one side or two volumes of road lighting to improve the safety of people traveling at night It is used to increase the time of people's outdoor activities and improve the safety of life and property. [0003] When the lawn lamp is used, the heat generated by the light source needs to be well dissipated to make the lawn lamp have a longer service life. The heat sink in the existing lamps is plate-shaped or sheet-shaped. The ventilation of the heat sink The performance is relatively insufficient, which affects the heat dissipation of the heat sink. Contents of the invention [0004] The purpose of the present invention is to provide a vertical lawn lamp with low cost, better ventilation perf...
