ANNEX I U.K. Technical parameters covered and definitions for the purposes of Annexes II to IV

1. TECHNICAL PARAMETERS FOR ECODESIGN REQUIREMENTS U.K.

For the purposes of compliance and verification of compliance with the requirements of this Regulation, the parameters below shall be established by reliable, accurate and reproducible measurement procedures, which take into account the generally recognised state of the art measurement methods.

(a)

‘Lamp efficacy’ (η_lamp), which is the quotient of the luminous flux emitted (Ф) by the power consumed by the lamp (P_lamp): η_lamp = Ф / P_lamp(unit: lm/W). The power dissipated by non-integrated auxiliary equipment, such as ballasts, transformers or power supplies, is not included in the power consumed by the lamp;

(b)

‘Lamp lumen maintenance factor’ (LLMF), which is the ratio of the luminous flux emitted by the lamp at a given time in its life to the initial (100 hour) luminous flux;

(c)

‘Lamp survival factor’ (LSF), which is the defined fraction of the total number of lamps that continue to operate at a given time under defined conditions and switching frequency;

(d)

‘Lamp lifetime’, which is the period of operation time after which the fraction of the total number of lamps which continue to operate corresponds to the lamp survival factor of the lamp, under defined conditions and switching frequency;

(e)

‘Chromaticity’, which is the property of a colour stimulus defined by its chromaticity coordinates, or by its dominant or complementary wavelength and purity taken together;

(f)

‘Luminous flux’ (Φ), which is a quantity derived from radiant flux (radiant power) by evaluating the radiation according to the spectral sensitivity of the human eye, measured after 100 hours of lamp running time;

(g)

‘Correlated colour temperature’ (Tc [K]), which is temperature of a Planckian (black body) radiator whose perceived colour most closely resembles that of a given stimulus at the same brightness and under specified viewing conditions;

(h)

‘Colour rendering’ (Ra), which is the effect of an illuminant on the colour appearance of objects by conscious or subconscious comparison with their colour appearance under a reference illuminant;

(i)

‘Specific effective radiant ultraviolet power’, which is the effective power of the ultraviolet radiation of a lamp weighted according to the spectral correction factors and related to its luminous flux (unit: mW/klm);

(j)

‘Lamp start time’, the time needed, after the supply voltage is switched on, for the lamp to start fully and remain alight;

(k)

‘Lamp warm-up time’, which is the time needed for the lamp after start-up to emit a defined proportion of its stabilized luminous flux;

(l)

‘Power factor’, which is the ratio of the absolute value of the active power to the apparent power under periodic conditions;

(m)

‘Luminance’, which is the amount of light, per unit of apparent surface, that is emitted by or reflected by a particular area within a given solid angle (unit: cd/m²);

(n)

‘Lamp mercury content’, which is the mercury contained in the lamp and is measured according to the Annex to Commission Decision 2002/747/EC(1).

2. DEFINITIONS U.K.

(a)

a ‘rated value’ is the value of a quantity used for specification purposes, established for a specified set of operating conditions of a product. Unless stated otherwise, all requirements are set in rated values;

(b)

a ‘nominal value’ is the value of a quantity used to designate and identify a product;

(c)

‘Second lamp envelope’ is a second outer lamp envelope which is not required for the production of light, such as an external sleeve for preventing mercury and glass release into the environment in case of lamp breakage, for protecting from ultraviolet radiation or for serving as a light diffuser;

(d)

‘Clear lamp’ is a lamp (excluding compact fluorescent lamps) with a luminance above 25 000 cd/m² for lamps having a luminous flux below 2 000 lm and above 100 000 cd/m² for lamps having more luminous flux, equipped with only transparent envelopes in which the light producing filament, LED or discharge tube is clearly visible;

(e)

‘Non-clear lamp’ is a lamp that does not comply with the specifications under point (d), including compact fluorescent lamps;

(f)

‘Switching cycle’ is the sequence of switching on and switching off the lamp with defined intervals;

(g)

‘Premature failure’ is when a lamp reaches its end of life after a period in operation which is less than the rated life time stated in the technical documentation;

(h)

‘Lamp cap’ means that part of a lamp which provides connection to the electrical supply by means of a socket or lamp connector and, in most cases, also serves to retain the lamp in the socket;

(i)

‘Lamp holder’ or ‘socket’ means a device which holds the lamp in position, usually by having the cap inserted in it, in which case it also provides the means of connecting the lamp to the electric supply.
