L946D947_SRC.QXD 11-03-2004 08:15 Pagina 12.8 Information – Specification data luminaires Protection against mechanical shock The impact resistance of a luminaire defines the protection of the luminaire against mechanical shock.The European norm EN 50102 defines the degrees of protection against external mechanical impact (IK code) and the method of testing.The luminaire housing should withstand the defined energy of the mechanical shock without losing its electrical and mechanical safety, or the basic luminaire function. Translated into a more practical implementation, this means that after withstanding the shock, deformation of the mirror and housing is allowed, although broken lamps, an unsafe electrical situation and failure to meet the specified IP classifications are not permitted. The impact resistance is expressed as a group numeral, for instance IK06, which is related to the impact energy in joule. Ball impact resistance Especially for indoor sports halls, ball-impact-resistant luminaires are essential.As no European norms have been developed, Philips Lighting has classified the relevant luminaires according to the German DIN 18032.According to this norm, luminaires should be tested with a ball shooting machine: the luminaire should be targeted by 36 handballs with a speed of 60 km/h. After the test, no essential damage to the luminaire should have occured. No loose particles should drop down from the luminaire. The symbol for a ball-impact-resistant luminaire is a football. Luminaires with a grid width exceeding 60 mm are not to be used in tennis sports halls. Flammability From the point of view of flammability, luminaires can always be mounted on non-flammable building materials like concrete and stone. However, when mounting luminaires on flammable materials special measures should be taken. Luminaires for discharge lamps with an F-sign are suitable to be mounted on building surfaces which do not ignite below 200°C. Luminaires for discharge lamps with an FF-sign have a limited surface temperature, and are suitable to be mounted on easily flammable surfaces. All types of luminaires of Philips Lighting have a minimum impact resistance of 0.2 J.The table shows the ten IK classifications and the defined shock energy in joule. For example: an IK07 classified luminaire can withstand a mechanical shock of a pendulum hammer, a spring hammer or a free-falling hammer of 2 joule (e.g. a hammer of 0.5 kg falling 0.40 m). Note that vandal-proof Iuminaires are not available: vandal-protected and vandal-resistant are the best achievable classifications.

F F Suitable for mounting on Ignition temperature easily flammable surfaces materials < 200°C; no combustion time lag … m Safety distance Especially in the application of reflector lamps and luminaires with narrow beam distributions, a minimum distance between light source and illuminated surface has to be ensured.This is to prevent too high temperatures.Values for safety distances are specified on the luminaire's packing.The specified values must be considered as the shortest distances permitted between the light source and the illuminated surface or object.
L946D947_SRC.QXD 11-03-2004 08:15 Pagina 12.9 Gear types Fluorescent lamps and high-intensity discharge lamps require a device to limit the current due to the negative current-voltage characteristics.Traditionally this is realised with electromagnetic control gear in combination with either a glow-switch or electronic starter.Almost the complete range of fluorescent and high-intensity discharge luminaires of Philips Lighting are available with the electromagnetic ballast system. From the point of view of energy consumption, the electromagnetic control gear system is not efficient: the losses in the ballast system are relatively high, and significant improvements are possible by applying electronic control gear instead. Electronic control gear offers a number of advantages in comparison with traditional electromagnetic ballasts: - The electronic ballast offers interesting cost savings, such as a reduction in energy consumption of about 25%, a substantial extension of the lamp life up to 50% and thus a lowering of maintenance costs. - Application of electronic ballasts adds to the comfort in numerous ways: no cathode flicker occurs; at the end of lamp life the lamp is automatically switched off; smooth and rapid starting is ensured without flickering; and no stroboscopic effects can arise due to the high frequency at which the lamps are operated. - Extra safety is assured through over-voltage detection, protected control of the mains voltage input and a noticeably lower operating temperature. - Flexibility is enhanced: installations with fluorescent lamps, for instance, are dimmable if a regulating ballast is selected, allowing for adjustment of lighting levels to personal preference and the opportunity for additional savings on energy, e.g. by daylight-linked lighting control. Following the trend towards greater efficiency and comfort, some of the newer fluorescent lamps like all TL5 and high-wattage PL-L types will operate only on electronic control gear. Philips offers four options when selecting high-frequency ballasts for fluorescent lamps: HF-BASIC for situations with infrequent onand-off switching; HF-PERFORMER where the demands are greater; HF-REGULATOR for areas where there is frequent dimming; and HF-DALI ballast working in accordensie with the DALI Protocol. - HF-DALI (HFD): Electronic regulating ballast for TL5, PL-L and TL-D lamps. The high-frequency regulating ballasts permit light output regulation down to 3% of the DALI control input. - HF-REGULATOR (HFR): Electronic regulating ballast for TL5, PL-L and TL-D lamps. These high-frequency regulating ballasts permit light output regulation down to 3% of the maximum light output by the 1-10 V control input. Up to 60% reduction in energy consumption can be achieved by using automatic lighting control systems like Luxsense or Multisense.All Philips HF-Regulator electronic ballasts are fitted with alpha-control.This dedicated integrated circuit ensures that lamp life is unaffected by the dimming position; that lamp burning is stable in every dimming position; and that energy savings are maximised when dimming. - HF-PERFORMER (HFP): Electronic ballast for TL5, PL-L and TL-D lamps. These high-frequency ballasts offer low energy consumption. A warm-start circuit preheating the lamp electrodes enables the lamp to be switched on and off without reducing useful life. - HF-BASIC (HFB): Electronic ballast for TL-D lamps (only for 36 W and 58 W lamps) These high-frequency ballasts offer low energy consumption. Luminaires with these ballasts are only to be applied in situations where switching is infrequent as the lamp electrodes are not preheated (‘cold start’) before ignition.
