Glossary IEC 60598 test report This standard specifies general requirements for luminaires, incorporating electric light sources for operation from supply voltages up to 1000 V. The requirements and related tests of this standard cover: classification, marking, mechanical construction and electrical construction. EMC test report EMC for electrical/electronic items intended for lighting purposes is covered by the standards EN55015 (EMC emissions) and EN61547 (EMC Immunity). These standards specify various emissions and immunity test to be carried out on the product either through radiated means or by conduction along the signal or power supply cables. In particular, EN55015 calls for magnetic field emissions and insertion loss measurements on certain types of devices. How to construct a technical brief for LED road lighting project. The existence of globally recognized LED product standards makes it easier to ascertain the competence of competing LED products. This is especially useful when calling for tender of a major road lighting project. This section clearly Photo-biological test report This test report covers the optical radiation safety of electrically-powered sources which are emitting light in the spectral region 200-3000nm. Whilst standards can vary between geographies, they should show high commonality to the international standard IEC62471:2006. describes the recommended elements (e.g. CIE compliance) to be included in the tender to ensure optimal light LED Chip IESNA LM-80 Test Report The LED Chip IESNA LM-80 Test Report with a prediction/extrapolation as per TM-21 should be available from the LED Chip Manufacturer. This test only refers to chip level performance. This is different than the LM79 report which gives an overview total luminous flux, luminous intensity distribution, electrical power, efficacy (lumens per watt delivered), and color characteristics (chromaticity, CCT, and CRI). The template is available by contacting your local Philips representative. Vibration test report The vibration test is executed in accordance with IEC60598 and takes into account vibration over all three axes. Salt Spray test report (500 hours) The salt spray test is a standardized test method used to check corrosion resistance of a fixture and is defined by ISO9227. Photometric files The photometric files give an overview on the optical performance of the fixture and must be used to design the optimal road lighting set-up. LED Driver test reports on Safety and Performance The driver should be tested on safety and performance by EN61347 and EN62384 respectively. Lab test report To make sure the test reports are from a reliable source and the tests are executed in the right way, make sure the lab is accredited and can provide an ISO17025 test report. CIE115 The CIE115 is the most important and leading application standard. It provides design guidance, given the type of road, usage and other relevant parameters. Philips is one of the members of the CIE standardization board and can help you in designing the optimal road lighting set-up. Glare Glare occurs where there is discomfort or a reduced ability to see caused by a light source that is too bright compared with its background. Glare can be reduced by dimming the source, blocking the direct view or increasing the background level of luminance. Color Rendering Index (CRI) CRI, Color Rendering Index shows how well a light source reveals colors. It compares the light source such an LED with a reference standard such as daylight or a filament lamp. Until recently, the comparison was based on eight standard colors and known as Ra8. An alternative for light sources uses 14 colors, Ra14. This has six additional saturated colors and gives a better indication of the LED’s ability to reproduce colors. A good LED road lighting system has a CRI > 70. Luminaire Lumen depreciation Test Report for 1000/2000/3000 hrs The luminaire lumen depreciation at a certain operating temperature tested to LM-79 standards should be available. The LM79 report which gives an overview of lumen depreciation, luminous flux, luminous intensity distribution, electrical power, efficacy (lumens per watt delivered), and color characteristics (chromaticity, CCT, and CRI) on a luminaire level for 1000, 2000 & 3000 hours. conditions.
