Description
Technical Field
[0001] The utility model relates to the technical field of underground lamps, in particular to an environmentally friendly LED underground lamp. Background Art
[0002] Underground lights are lighting facilities embedded in the ground. They are widely used in squares, parks, lawns and other places due to their small size and high aesthetics. Compared with traditional street lights, they do not require the installation of tall light poles, which not only reduces the installation cost, but also simplifies the installation steps and can prevent pedestrians from hitting the street lights.
[0003] After the underground lamp is installed, only the light-transmitting glass panel is left above the ground surface. The highly light-transmitting panel is easily worn out in harsh environments such as pedestrians stepping on it and vehicles running over it. In rainy and snowy weather, the smooth surface of the glass panel can easily cause pedestrians to slip. Especially at this stage when cycling is popular, if a road bike passes over the top of the underground lamp during braking, it is easy to slide and fall off the bike, which not only poses a hidden danger to personal safety, but also easily causes damage to the highly brittle carbon fiber frame. Therefore, it is very necessary to manufacture an underground lamp that can protect the light-transmitting panel and has an anti-slip effect. Utility Model Content

DETAILED DESCRIPTION

[0024] See also Figure 1 and Figure 2 An environmentally friendly LED underground lamp comprises a lamp body 1 and an embedded part 2. The lamp body 1 is spherical. The embedded part 2 comprises a top cover 21, a lamp holder 22 and a driving compartment 23. The lamp body 1 is placed in the hemispherical concave surface at the top of the lamp holder 22. The top cover 21 is buckled on the top surface of the lamp holder 22 and covers the lamp body 1 therein. The top cover 21 and the lamp holder 22 are fixedly connected by screws. The top surface of the driving compartment 23 is fixedly connected to the bottom surface of the lamp holder 22. The interior of the driving compartment 23 is provided with an adsorption plate 3, an air bag 4 and an electromagnet 6 from top to bottom.
[0025] See also Figure 2 , Figure 3 and Figure 5A lighting module is provided on the top surface of the lamp body 1, and a rotating shaft 13 is fixedly installed on the side surface of the lamp body 1. The axis of the rotating shaft 13 passes through the geometric center of the lamp body 1 and is parallel to the top surface of the lamp body 1. A transmission tooth 15 is fixedly installed on the outer end of the rotating shaft 13, and a wiring hole 14 is opened at the axis center of the rotating shaft 13, and the wiring hole 14 is used to lay wires. Rolling grooves 221 are provided on the buckling surfaces of the top cover 21 and the lamp holder 22, and the rotating shaft 13 is movably engaged in the upper and lower rolling grooves 221. The lamp body 1 rotates around the rotating shaft 13 inside the embedded part 2. The side surface of the lamp body 1 includes a spherical surface and a plane, wherein the plane part is rotationally symmetrical with the top surface of the lamp body 1 about the axis of the rotating shaft 13. The spherical surface is provided with heat dissipation fins 11, and the plane is provided with plane fins 12. When the buried lamp is turned on, the top surface of the lamp body 1 faces upward to provide lighting, and when the buried lamp is turned off, the plane fins 12 face upward to prevent people from slipping due to the smooth glass panel on the top surface of the lamp body 1, and at the same time, the lighting module on the top surface of the lamp body 1 is hidden under the ground for protection.
[0026] See also Figure 3 The spherical side surface of the lamp body 1 and the inner concave surface of the top of the lamp holder 22 are provided with mounting grooves 222 along the rotation direction of the lamp body 1. A support wheel 223 is fixedly installed in the mounting groove 222 on the top of the lamp holder 22. The support wheel 223 is rotatably connected to the lamp holder 22. The support wheel 223 is used to bear the weight of the lamp body 1 above and the pressure of pedestrians stepping on it.
[0027] See also Figure 2 , Figure 4 and Figure 6 An electromagnet 6 is fixedly installed on the bottom surface of the driving chamber 23, an airbag 4 is arranged above the electromagnet 6, a compression spring 41 is arranged inside the airbag 4, and the two ends of the compression spring 41 are respectively fixedly connected to the top and bottom surfaces of the airbag 4, and an adsorption plate 3 is fixedly installed on the top of the airbag 4, and a rack 31 is fixedly installed on the top surface of the adsorption plate 3, the rack 31 penetrates the lamp holder 22 and meshes with the transmission gear 15 above for transmission. When the lamp body 1 is energized, the electromagnet 6 is energized and adsorbs the adsorption plate 3 above, and the adsorption plate 3 drives the rack 31 to move downward and compress the airbag 4 and the compression spring 41, and the rack 31 meshes with the transmission gear 15 for transmission, thereby driving the lamp body 1 to rotate around the rotating shaft 13, so that the top surface of the lamp body 1 faces upward to provide lighting.
[0028] See also Figure 2 , Figure 4 and Figure 7A nozzle 52 is provided on the inner wall of the top cover 21 at the upper part of the lamp body 1, and a continuous air duct 51 is provided inside the top cover 21 and the lamp holder 22. The top of the air duct 51 is connected with the nozzle 52, and the bottom of the air duct 51 is fixedly connected with one end of the bellows 5. The other end of the bellows 5 passes through the adsorption plate 3 and is connected with the interior of the airbag 4. When the adsorption plate 3 compresses the airbag 4 and the compression spring 41 downward, the gas in the airbag 4 passes through the bellows 5 and the air duct 51 successively and is then ejected by the nozzle 52 to blow away the sand on the top of the top cover 21 to prevent the sand from entering the interior of the embedded part 2 and damaging the underground lamp when the lamp body 1 rotates.
[0029] The usage (working principle) of the utility model is as follows:
[0030] After the underground lamp is installed and the circuit is turned on, the electromagnet 6 is energized and attracts the adsorption plate 3 to move downward. The adsorption plate 3 drives the rack 31 to compress the airbag 4 and the compression spring 41 downward. On the one hand, the rack 31 is engaged with the transmission tooth 15 to rotate the lamp body 1 along the rotating shaft 13, and the lighting module of the lamp body 1 is flipped to the top to provide lighting. On the other hand, the gas inside the airbag 4 is finally ejected by the nozzle 52 through the bellows 5 and the airway 51, blowing away the sand on the top of the top cover 21 to prevent the sand from falling into the gap generated when the lamp body 1 rotates.
[0031] After daybreak, the power supply is stopped, the electromagnet 6 and the adsorption plate 3 are separated, the airbag 4 expands upward and resets under the elastic force of the compression spring 41, and the adsorption plate 3 and the rack 31 rise accordingly. The rack 31 drives the lamp body 1 to rotate through the transmission tooth 15, so that the flat fin 12 faces the top. On the one hand, the uneven structure of the flat fin 12 increases the anti-slip effect of the top of the underground lamp to prevent the smooth light-transmitting plate from causing people to slip or fall. On the other hand, the lighting module is buried underground to prevent the lighting module of the lamp body 1 from being damaged by factors such as pedestrians stepping on it and tool wear during the day.
