Traffic lights are made from red ( expressed prohibition of passage ) , green ( which means allowing passage ) , yellow ( expressed alarm ) components. Divided into: motor vehicle lights , bicycle lights, crosswalk lights, driveway lights, directional lights, flashing warning lights, roads and level crossing lights.2.Advantages:1) With aluminium alloy material of the lamp, it has favorable oxidizability, impact property and anti-acid property.2)Using high power led 1W as the light source, with unique lighting design;select for excellent imported semiconductor chip, it has high thermal conductivity, low luminous decay, pure colors and no heavy shade ;3) Using high heat-dispersion aluminium-magnesium alloy material with unique finned type design, the radiator and lamp integration, control the LED junction temperature in a allowed range efficiently.4) With high color rendering index which can show a true color of things for people and meet the requirement of different invironment, clear up the depressive mood caused by lower or higher color temperature compared with conventional lamp, make more comfortable for people's eyes;5) Wide voltage range available and global universal adopted advanced cnstant-current controlling techniques, can fast tum on, no warn-up;6) Using high quality power supply systems, easy to install and little maintenance cost.
