What are the technical parameters required for traffic lights?

A traffic light is a silent "traffic policeman". A red light is a stop signal, and a green light is a go signal. Intersection, several directions to the car are gathered here, some to go straight, some to turn, so that those who go first follow the traffic lights command. Red light, no straight or left turn, without hindering pedestrians and vehicles, allow vehicles to turn right; Green light, allowing vehicles to go straight or turn; Yellow light, stop in the intersection stop line or crosswalk line, has continued to pass; When the yellow light flashes, it warns the vehicle to pay attention to safety.
A light-emitting diode (LED) is used as the light source for a traffic signal lamp. Under the rated voltage of 220V AC, the power of a single light-emitting unit does not exceed 25W.
The rated working voltage of the power supply of the traffic signal lamp is AC220V and 50Hz; When the power supply voltage fluctuates in the range of AC220V, 44V, and 50Hz 2Hz, it can work normally.
Traffic light technical data and related requirements:
The luminous intensity is: red and yellow LED diode luminous intensity is greater than 600mcd, using ultra-high brightness four-element LED as the light source, in line with the international industrial level II anti-static (ESD-2000) standard. The light intensity of the green LED tube is greater than 6000mcd, which is sealed by an American CREE chip. The light color conforms to the regulations of GBI14887. Chromaticity requirements: red 625nm, yellow 590nm, green 505nm.
The traffic signal light USES four light combination type. Red, yellow, and green are full-screen lights and digital displays. Plateful lamp arranges a way to want intensely. LED service life is not less than 80,000 hours, and the LED signal light's visual distance is not less than 1000 meters. Single lamp power consumption is less than 10 W, operating voltage is AC180-260, no color change. PCD circuit boards are rigid printed circuit boards made of flame-retardant materials and tinned. The coating is non-oxidized with a thickness of over 1.8mm. The lead wire of each light-emitting unit shall be a wire that conforms to the national electrical standards, and the wire diameter shall not be less than 1.5mm. All components were aging tested, and electrical and optical parameters were tested.
The inlet of traffic signal lamps is provided with reliable measures of insulation, waterproofing, and dustproofing to ensure that the road traffic signal lamps are not lower than the IP53 protection level.
The shell structure is rigorous, with a beautiful appearance, a strict seal, moisture-proof, and dustproof.
1. The traffic signal light shall comply with gb14887-2003 (technical requirements and test methods of road traffic signal light).
2. The technical indicators of traffic lights are tested by the product quality supervision and testing center of the Ministry of Public Security, and corresponding test reports are available.
3. The traffic signal light lens is made of polycarbonate with high light transmittance and has a service life of 10 years.
4. All the seals in the traffic lights are made of silicone rubber, and no aging or hardening will occur during the 10-year trial period at high and low temperatures.
5. Operating voltage: AC220V 44V 50HZ 2, power 12W.
6. Wavelength: red 625nm, yellow 590nm, green 505nm.
7, environment humidity: - 40 ℃ to 70 ℃, relative humidity ≦ 93%.
8. Visual range of 35

Street lighting plays a vital role in creating safe, functional, and vibrant urban spaces. It ensures visibility for vehicles and pedestrians, reduces nighttime accidents, and enhances the overall quality of city life. However, street lighting systems can only operate reliably and efficiently when backed by regular maintenance. In this blog, we explore why maintenance matters, what challenges typically arise, and how Luxega provides a unique solution for keeping both modern and legacy lighting systems at peak performance.

Why Street Lighting Maintenance Is Essential
Without preventive maintenance, street lighting systems gradually degrade. Dimming lights, component failures, and contaminated surfaces can all pose safety risks, reduce energy efficiency, and increase long-term costs. Routine inspections and cleaning, timely replacement of components, and monitoring of electrical performance help:

Prolong the lifespan of lighting systems

Maintain light quality and coverage

Reduce energy waste

Prevent safety hazards caused by component failure or electrical faults

Common Maintenance Challenges
Street lighting systems face several issues over time:

LED driver or surge protection failure

Light decay or reduced lumen output

Contamination of lenses and enclosures

Aging or damaged wiring and seals

Poor heat dissipation reducing LED performance

To maintain the desired lighting level and compliance with street lighting standards, these components must be regularly inspected and replaced.

Luxega’s Role in Smart Maintenance
At Luxega, we offer a tailored approach to lighting maintenance by supplying component-level replacements for a wide range of existing LED street lights. This includes:

Custom LED boards for seamless integration

High-quality LED drivers from leading global brands

20kV surge protection devices for enhanced safety

Our components are designed to be 100% compatible with the original luminaire housing, making retrofits and repairs both efficient and cost-effective. Whether you're maintaining a modern LED street light or upgrading a traditional fixture, Luxega ensures a perfect fit with reliable performance.
