Embodiment 1

[0027] This embodiment provides a street lamp, which is evenly arranged on the guardrails on both sides of the road. The street lamp in this embodiment is used for lighting road sections in foggy areas, such as figure 1 As shown, it includes: a light box 1 fixedly arranged on the guardrail, wherein the vertical height of the light box 1 from the ground is between 0.7m-1.5m, and the installation interval of every two light boxes 1 on the guardrail is between 4m-8m The high color temperature LED bead 2 is set inside the light box 1; the transparent window 3 is set outside the light box 1, and its surroundings are disassembled and connected with the light box 1; the lampshade 4 is set on the top of the light box 1.

[0028] Specifically, the light box 1 is fixed and installed on the guardrails on both sides of the road through some screws, and is mainly used to protect the high color temperature LED lamp beads 2 installed inside it. On the one hand, it prevents rainwater from infi...

Embodiment 2

[0036] This embodiment provides a street lamp, which is applied to road section lighting in foggy areas. In this embodiment, through the analysis of the fog generation mechanism, the experiment is carried out by simulating the environment of the fog area, and the influence of the fog on the driver's visual recognition is studied, and it is obtained that the illuminance and visibility of the light source are the same, and the driver's visual recognition distance increases with the increase of the color temperature. And improve.

[0037] Specifically, a road without traffic was selected. In order to make the experimental environment on both sides of the guardrail controllable and not affected by the reflection of the top, side and ground materials, black cloth was used to create a night effect. The color temperature range of the street lamps in this example is 7000K-10000K. In order to make the experimental effect stand out, the current green and energy-saving LED light sources ...

Abstract

The invention discloses a streetlamp. Streetlamps are evenly arranged on guardrails on two sides of a street and used for illumination in foggy road sections. The streetlamp comprises a lamp box, high-color-temperature LED beads, a transparent window and a lampshade, wherein the lamp box is fixedly arranged on a guardrail; the high-color-temperature LED beads are arranged inside the lamp box; the transparent window is arranged outside the lamp box, and the periphery of the transparent window is detachably connected with the lamp box; and the lampshade is arranged at the top of the lamp box. The streetlamp provided by the invention adopts the high-color-temperature LED beads, the visual recognizing capacity of drivers or pedestrians can be improved, and drivers can safely drive on foggy days, see distant obstacles clearly and avoid the obstacles in time, so that traffic accidents are avoided, and the life and health of drivers are effectively ensured.

Description

technical field [0001] The invention relates to the technical field of road lighting, in particular to a street lamp. Background technique [0002] Street lamp is a kind of lamp that provides lighting function for the road. It is generally widely used in road traffic to provide light for pedestrians or drivers in dark night or foggy days, thereby enhancing their visual recognition. Among them, when the air in a foggy day is full of small water droplets, it will scatter the light, resulting in reduced visibility, which seriously affects people's visual recognition. Therefore, for drivers driving in foggy days, it is easy to cause drivers The vision is blurred, so in order to ensure the safety of the driver, it is necessary to set up some street lights to improve the visual recognition effect in the foggy road section. [0003] At present, most street lamps on the market generally use low color temperature light sources below 3000K. Because the proportion of short-wave in the...
