LED underground lamp

Abstract

The invention discloses an LED underground lamp. The LED underground lamp comprises a lamp box. The lamp box is divided into two layers, the upper end of the lamp box is a mounting cavity, and the lower end of the lamp box is an electric cavity. A sealing plate is arranged on the top of a lamp body assembly. A spring is mounted at the bottom of the lamp body assembly. The bottom of the spring is fixedly connected with the bottom face of the mounting cavity, and the top of the spring is fixedly connected with the lower end face of the lamp body assembly. One or more circles of stepped faces are arranged on the inner wall of the opening end of the upper end of the lamp box. An automatic cleaning mechanism is arranged in the lamp box. The automatic cleaning mechanism is extruded when the sealing plate descends, water is drained through water outlet holes in the stepped faces, and the end face of the outer side of the sealing plate is cleaned. By the adoption of the LED underground lamp, the sealing plate can descend when a non-motor vehicle travels, tires of the non-motor vehicle are in contact with the stepped faces of the lamp box, the situation that the water is accumulated on the sealing plate and sliding is caused is solved effectively, the use is safer, the automatic cleaning is achieved through extrusion, the cleanness of an upper end panel is guaranteed, and the light extracting rate is guaranteed.

Description

technical field [0001] The invention relates to the field of lamps, in particular to an LED underground lamp. Background technique [0002] Buried lights are currently used in many occasions. The light emitting surface of the buried lights is flush with the ground, so that it will not stumble and will not affect normal traffic. However, its upper end surface is a transparent light-emitting surface, so it is very slippery in rainy days, especially for pedestrians and non-motorized vehicles. When the tire contacts the transparent surface at the upper end, the vehicle will slip and roll over due to the loss of friction. , the probability is relatively high, because it is too late to reflect whether there are buried lights here when riding. [0003] Furthermore, the light output effect of the buried light depends on the cleanliness of the panel. Since the surface of the panel is in contact with the outside world, a large amount of dust will accumulate after long-term use, resul...

Problems solved by technology

However, its upper end surface is a transparent light-emitting surface, so it is very slippery in rainy days, especially for pedestrians and non-motorized vehicles. When the tire contacts the transparent surface at the upper end, the vehicle will slip and roll over due to the loss of friction. , the probability is relatively high, because it is too late to reflect whether there are buried lights here when riding

[0003] Furthermore, the light output effect of the buried light depends on the cleanliness of the panel. Since the surface of the panel is in contact with the outside world, a large amount of dust will accumulate after long-term use, resulting in a low light output rate and affecting the normal light output of the buried light. clean
