EN 14744:2005 (E) 7 4 Minimum requirements 4.1
Luminous intensity and range 4.1.1 General I0 is the photometric luminous intensity in candela (cd) that, in the case of navigation lights with an electrical light source, is measured in the laboratory at rated voltage. Taking into account the ageing of the light source, contamination of the optical system and voltage fluctuations of the vessel power supply system, for example, the luminous intensity under operating conditions IB in candela (cd), for the values listed in the COLREGs is assumed to be 20 % less than the photometric luminous intensity I0.
Therefore, lB =
0,8
x I0 (cd) Where IB is the luminous intensity under operating conditions, in candela (cd) I0 is the photometric luminous intensity, in candela (cd) The range given on the navigation light depends on the interval for I0 in Table 1 in which the luminous intensity I0 actually measured lies. It is not permitted to mark a navigation light with a higher or lower figure.

If the luminous intensity of a navigation light is within the ranges specified in Table 1 for I0, the COLREGs, CCNR and CEVNI requirements may be considered to have been met. 4.1.2 COLREGs If the range of the navigation light is intended to meet only the COLREGs, the luminous intensities in
Table C.1 of normative Annex C apply instead of Table 1. 4.1.3 CCNR and CEVNI If the range of the navigation light is intended to meet only the CCNR and CEVNI regulations, the luminous intensities in Table D.1 of normative Annex D apply instead of Table 1. SIST EN 14744:2005



EN 14744:2005 (E) 8 4.2
Luminous intensity distribution 4.2.1 Horizontal luminous intensity distribution The requirements of the COLREGs apply.
According to the COLREG "almost zero" means a value of not greater than 10% of the photometric luminous intensity I0 measured in the zero signal direction (3.5) (dead ahead direction). In the case of two-colour or three-colour navigation lights, the luminous intensity distribution shall be uniform so that in the range of 3° on each side of the zero signal, the maximum permissible luminous intensity shall not be exceeded and the minimum required luminous intensity shall not be fallen short of. The horizontal luminous intensity distribution of the navigation light shall be uniform over the whole radiation angle so that the maximum and minimum values of the photometric luminous intensity do not differ by more than a factor of 1,5. The luminous intensities of the starboard and port lights shall not differ by more than a factor of 1,5. 4.2.2 Vertical luminous intensity distribution The requirements of the COLREGs apply. The maximum vertical luminous intensity shall not exceed the horizontal luminous intensity at
0° by more than a factor of 1,5.
Navigation lights with vertical luminous intensity distribution according to COLREGs, Annex I,
10 (a) specified for motor boats only shall be marked accordingly (three-bladed propeller). 4.3

If the colour locus of a navigation light is within the coordinates specified in Table 2, the COLREGs, CCNR and CEVNI requirements relating to colour loci are satisfied. NOTE The table corresponds to that in CIE No. 2.2 (TC – 1.6) – 1975; CIE S 004/E – 2001 “Colours of light signals” published by the CIE in 2001 was not regarded as being suitable. SIST EN 14744:2005



EN 14744:2005 (E) 9 4.3.2 COLREGs If the colour locus is intended to meet the requirements of the COLREGs only, the colour ranges in Table C.2 in normative Annex C apply instead of Table 2. SIST EN 14744:2005



EN 14744:2005 (E) 10 4.4 Flashing light
The ruling dimension for the range is the visually effective luminous intensity (IEFF). IEFF is a measure for the conspicuity and efficiency of the flashing light emitted.
IEFF shall attain at least the minimum horizontal photometric luminous intensity values I0 in Table 1.
IEFF is calculated as follows from the maximum instantaneous luminous intensity in the observation direction (IMAX) according to the Blondel-Rey equation:
IEFF = )(2,01221ttdtIttMAX−+∫
Where
IEFF
is the effective luminous intensity in candela;
IMAX
is the instantaneous value in candela;
0,2
is the Blondel-Rey constant for night observation in seconds;
t1 and t2
are the integration time limits in seconds.
If the duration of the light phenomenon less the rise time and decay time, i.e. the time in which the instantaneous luminous intensity attains or exceeds the required minimum luminous intensity, is greater than 0,3 s, the light may be regarded as a steady light.
The effective luminous intensity shall not then be determined.

The vertical radiation shall be at least 4°. With an inclination of the flashing light to the horizontal of up to ± 2°, the luminous intensities shall still be at least 80 % of the luminous intensity at 0°.

Light sources that correspond to the examples in Annex A meet the requirements of this standard. 4.10 Other light sources, e.g. light emitting diodes (LED) and their particularities 4.10.1 Deviations caused by service life conditions If a light source other than an incandescent lamp is used, the navigation light shall clearly indicate (e.g. by failure, similar to the burn out of an incandescent lamp) if the required range can no longer be attained (e.g. as a result of degradation - ageing - or failure of parts of the light source). 4.10.2 Influence of temperature 4.10.2.1 Influence of temperature on colour locus and luminous intensity
If something different to an incandescent lamp is used as the light source, it shall be ensured and tested that at ambient temperatures of – 25 °C to + 30 °C the luminous intensity and colour locus meet the requirements of this standard both one minute after switching on and after 120 min operation or after thermal equilibrium has been reached. The test shall be as described in 5.2.4. 4.10.2.2 Dry heat and low temperature The light source in the energized state shall withstand ambient temperatures of – 25 °C to + 55 °C without damage. 4.10.3 Pulse frequency If the light of a light source is timed electrically, this shall be done at a frequency of at least 100 Hz for steady lights so that the human eye does not notice the pulsing.
