chevy (fama) brand with good quality product to our country Algeria. First time we buy traffic light is 2010, every years we will buy one or two container. Their traffic light seldom give us problem in our project. Thanks very much for fama team backup support

—— Sam

we are agent for fama company in sri lanka, we've install 80% of new junction in sri lanka last five years, all use fama traffic light, government satisfy with our supplier and products. First junction products installed in 2011, wow it's still working. We trust each other.

—— damith

Fama products with good quality and good price to support us get more project tender. I am a west African client. Before i buy from Europe, After test fama products in 2012, all the main traffic lights i buy from fama from then on. Everything goes well, products quality, price, sales team attitude, professional, after sales warranty etc.

QC Profile

“Quality first” is the work ethic of every staff of Fama (ChevyLight), which comes through all procedures. Fama has already obtained ISO9001-2008 quality management system certificate and all other safety certificates (CE-EN12368、CCC、EMC、LVD、TUV、GB14887-2001 etc), which proves our long term and well cooperation with our customers.
Instead of handwork, the automatic machines have been adopted for the welding component, ..most production and testing processes are accomplished by automatic machines.

In order to avoid the potential defects existed in the design and production, we conduct a series of reliability tests such as the electronic performance test for the semi-finished products and finished products, the anti-dust test, the waterproof test, the anticorrosion test(salty spraying test ), the vibration test and thermal shock tester, etc.
The Reliability Test for the Semi-finished products: Before sealant-sealing for semi-finished modules and after QC inspection, more than 72 hours' aging should be made in the high temperature for all the Traffic Light products.
The Reliability Test for the Finished Products: Assembling the finished Traffic Light modules to the Shell and simulating the on-the-spot whole panel assembly, we keep them aging for more than 48 hours, during which, if no defects found, the delivery then can be made.
The Waterproof Test: During the high humidity environment, the waterproof performance of the Traffic Signal Light is quite important. Fama(ChevyLight) performs the high-pressure water-spraying test as well as submerging test, water-showering test against the front panel to ensure its waterproof performance in good state. Therefore, the waterproof degree of IP55 has been completely reached.
The Anticorrosion Test: In order to ensure the reliability of anticorrosion of the PCBs and the Shell treated by anticorrosion, hence, the salty spraying test must be made during the production.
The Simulated Vibration Test: Vibration in transit and typhoon, due to the operation of which is under the conditions of vibration, in order to ensure the reliability of the Traffic Lights, therefore, the simulated vibration test against the Traffic Light must be conducted.
The Simulated Installation Test: The debugging over the Traffic Light under the real outdoor environment can ensure the effects of display in factory are the same with the effects of display on-the-spot.

Fama(ChevyLight) has the advanced and precise apparatus & equipments to ensure the good quality of the products. Through many years of development, Fama(ChevyLight) has kept a leading position domestically in the aspects such as on-the-spot management, quality control, technical development mechanism and management check system etc. in China LED Traffic Light industry.

The processes are monitored by many kinds of precise instruments and parameters Definitions
2.1 Catastrophic Failure. The total loss of visible illumination from an LED light source.
2.2 Chromaticity. The color of the light emitted by the module, specified as x, y chromaticity coordinates on the chromaticity diagram according to the 1931 Commission Internationale d’Eclairage (CIE) coordinate system.
2.3 Conditioning. Energizing an LED signal module at a specified ambient temperature for a specified period of time, to cause any early electronic component mortality failures to occur and to detect any component reliability problems.
2.4 Countdown Pedestrian Signal. A two-digit numeric interval countdown display used to inform the pedestrians of the number of seconds remaining in the pedestrian change interval.
2.5 Duty Cycle. The fraction of time during a specified time period that the module is energized, expressed as a percentage of the specified time period.
2.6 Hard Coat. A surface coating or a film used to provide front surface abrasion resistance.
2.7 Illuminance. The density of the luminous flux incident on a surface. Its value is determined by luminous intensity, angle of incidence and distance from the source to the surface, expressed as lux.
2.8 LED Light Source. A single light emitting diode (LED) or an array of LEDs.

2.9 LED Pedestrian Signal Module (module). A signaling unit comprised of an array of LEDs and related power supply and any required lenses, which, when connected to appropriate power, provides a pedestrian signal indication consisting of a “walking person” or “upraised hand” icon or both.
2.10 Luminance. The luminous flux emitted or reflected from a surface, in a given direction, per unit solid angle, divided by the area of the surface, expressed as cd/m2.
2.11 Luminous Intensity. The luminous flux emitted in a given direction from a source, per unit solid angle, expressed in candelas (cd).
2.12 Minimum Maintained Luminance. The minimum luminance a module is required to provide throughout service as a pedestrian indication or countdown display.
2.13 Nominal Operating Voltage. The AC RMS voltage, 120 VAC, at which photometric performance and power consumption are specified.
2.14 Pedestrian Change Interval. Period of time when “upraised hand” icon is flashing to advise the Pedestrians that they should leave and /or not enter the intersection.
2.15 Power Consumption. The electrical power in Watts consumed by the module when operated at nominal operating voltage and ambient operating temperature range.
2.16 Power Factor (PF). PF equals Watts divided by Volt-Ampere (VA) or the ratio of power consumption in Watts to Volt-Amperes.
2.17 Total Harmonic Distortion (THD). THD is the ratio of the root-mean-square (RMS) value of the harmonics to the amplitude of the fundamental component of the AC waveform.
2.18 Translate. To move an object along a linear vector, such that the orientation of the object does not rotate relative to the original frame of reference.
2.19 Turn OFF Time. The amount of time required after removal of the nominal operating voltage for the LED signal module to show no visible illumination.
2.20 Turn OFF Voltage. The voltage below which the LED signal module emits no visible illumination.
2.21 Turn ON Time. The amount of time required for the LED signal module to reach 90 percent of full illumination.
2.22 Volt-Amperes. The product of root-mean-square (RMS) line voltage and RMS line current measured with true RMS meter.
