A kind of led street light

Abstract

The invention discloses an LED street lamp which comprises a light source module and a lamp holder. The light source module comprises a back plate and a lampshade. LED beads are arranged in a cavity composed of the back plate and the lampshade. The matched connection faces of the back plate and the lampshade are each provided with a concave-convex component and form a sealed structure. The lamp holder is provided with an installation station and used for being connected with the light source module or an extending frame. The extending frame is used or being connected with the light source module. By applying the LED street lamp, the number of light source modules on the LED street lamp can be set according to the requirement for the illumination intensity, the main body structure of the lamp holder is not changed, only connection of the extending frame is needed when the multiple light source modules are arranged, and therefore the production, purchasing, installation and maintenance cost of the lamp holder can be effectively reduced; meanwhile, the matched faces of the back plate and the lampshade of the light source module are provided with the concave-convex components to form the labyrinth seal structure, and therefore rainwater can be effectively prevented from entering the light source modules. The LED street lamp is simple in structure, low in cost, convenient to machine and manufacture, and capable of effectively protecting the LED beads against a short circuit caused by rainwater and delaying aging of the LED beads.

Description

technical field [0001] The invention relates to the technical field of lighting, in particular to an LED street lamp. Background technique [0002] In the field of lighting technology, LED (Light Emitting Diode), as an emerging light source, is gradually replacing existing light sources, such as incandescent lamps and energy-saving lamps. In addition to long life and low energy consumption, LED light sources also have the advantages of no radiation, no heat, and easy recycling. They are typical green lighting sources. LED lights have the characteristics of energy saving, environmental protection, low power consumption, long life, rich colors, vibration resistance, and strong controllability. [0003] The integration level of existing LED street lamps is not high, and the relatively low production efficiency is also an important reason. Most of the existing LED street lamps are designed and manufactured as a whole, and various products do not have versatility and interchange...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to overcome the low degree of modularization and integration of LED street lamps in the prior art, poor replaceability, high maintenance costs, and poor rainproof design. Rainwater enters the interior of the lamp, which easily causes circuit short circuit and burns LED lamp beads. , or may erode the above-mentioned shortcomings of LED street lamps and cause accelerated aging of LED street lamps, and provide an LED street lamp
