통이미지
1
The amount of traffic is large, and the amount of traffic is large when the ADDT is 25,000 or more per year, and traffic is small when it is less than 25,000.
2
The complexity of road alignment means the basic structure of the road, the movement of vehicles and the visual environment.
- Number of lanes, number of slopes
- Traffic lights and signs
3
Traffic control refers to the presence of signs and signs and the presence of signs. Means of control include traffic light, rules of right of way, laws and signs of priority, traffic signs, direction signs and road signs. If there is no such means or is poor, traffic control is considered to be insufficient.
4
Other types of road users are, for example, cars, trucks, low speed vehicles, buses, bicycles, pedestrians, and the like.
5
Detachment can be by way of a private lane or by imposing restrictions on one or more forms of traffic If there is such a separation, a low-grade illumination can be performed.

LED lighting introduction

LED stands for Light Emitting Diode, which means a light emitting diode. This is a semiconductor element used to send and receive signals by converting electric signals into infrared rays or light using the characteristics of compound semiconductors. It is used for household appliances, remote control, do.

Advantages of LED lighting

  • Highly efficient luminous flux close to streetlight (chip device 70 lumens or more / W)
  • 50% ~ 70% reduced power consumption
  • Reduced maintenance costs
  • Long product life and high luminance (streetlight brightness over)
  • Dustproof, waterproof and eco-friendly products for outdoor installation
  • Application of high efficiency POWER LED PACKAGE technology
  • Large, medium and small variety of products
  • Realize different colors
  • Stable design structure (efficient light distribution design)
  • No warm-up time due to momentary lighting
  • Stable power supply by development of solar LED controller (no inverter required)

LED Lighting Technical Features

  • Single ramp float maximizes beam speed.
  • Reflector and lens stage for improved light efficiency and direction of light.
  • Complete heat dissipation troubleshooting.
  • Step 1: Designing a stable heat lamp.

      -It can be used for various purposes such as parks and crime prevention, golf course, life sports facilities, etc. where bright lighting is needed.

Light source

It refers to objects that generate light themselves such as the sun, objects that reflect light from the sun, such as the moon, lights, neon signs, and artificially illuminated devices such as light emitting diodes.

Luminous flux

The total amount of light emitted per second by the light source is called the luminous flux, and the lumen ([lm]) is used as the unit.

Luminous intensity

The light intensity of the light source is called the luminous intensity. The luminous intensity of the light source indicates the luminous flux density is large and small, and its unit is candela ([cd]).

Luminance

Luminance refers to the amount of light that appears when it is viewed from any direction.
The unit uses L for cd / ㎡ symbol.

Glare

Glare occurs when an eye is hit by a light source that produces a much brighter light than the average ambient light, which causes discomfort, eye strain, and difficult conditions.
