LED street lamp and production process thereof

Abstract

The invention discloses an LED street lamp and a production process thereof.The LED street lamp comprises a lamp pole and a lampshade arranged on one side of the lamp pole, a substrate is fixedly connected to the interior of the lampshade, a circuit board is fixedly connected to the bottom of the substrate through bolts, a lamp tube electrically connected with the circuit board is arranged at the bottom of the substrate, a protective cover is arranged on the outer side of the lamp tube, and the protective cover is arranged on the outer side of the lamp tube. The lampshade is composed of a side plate and a water storage tank communicated with the side plate, and an air inlet pipe and an exhaust pipe are arranged on the two sides of the lampshade respectively. The connecting rod drives the sliding plate in the water storage tank to move downwards, when the sliding plate moves downwards, water in the water storage tank can be squeezed into the drainage pipe and then sprayed out through the mist spraying holes in the outer side of the drainage pipe, and due to the fact that the diameter of the mist spraying holes is small, fine water columns or mist-shaped water drops can be sprayed out; and moreover, the water drops drop on the top of the substrate, and the heat on the substrate can be absorbed through the dropped water drops, so that the heat dissipation effect is achieved.

Description

technical field [0001] The invention relates to the technical field of LED street lamps, in particular to an LED street lamp and a production process thereof. Background technique [0002] LED street lamps are semiconductor lighting lamps. It is a high-efficiency solid-state light source that can emit light with weak electric energy based on the semiconductor PN junction. Under a certain forward bias voltage and injection current, the holes injected into the P region and the electrons injected into the N region diffuse to the The active area then emits photons through radiative recombination, which converts electrical energy directly into light energy. It is a solid-state cold light source, which has the characteristics of environmental protection, no pollution, low power consumption, and high luminous efficiency. Therefore, LED street lights will become the best choice for energy-saving renovation of road lighting. [0003] However, during the use of traditional LED stree...

Problems solved by technology

[0005] The purpose of the present invention is to provide an LED street lamp to solve the problem that the circuit board inside the lamp is seriously heated due to long-term work during the use of the traditional LED street lamp proposed in the above background technology, especially in hot weather. However, due to the small internal space of the lamps and the tight arrangement of components, only relying on cooling fans or other single heat dissipation methods to cool them down, the effect is not satisfactory, resulting in circuit damage in a large number of street lamps after a period of use, thus Problems that lead to unusable street lights
