Voorbeeldzinnen

1. Luminous efficacy
2. Luminous flux
3. Rated luminous flux;
4. Deduction from luminous efficacy at 25 °C
5. ‘Objective luminous flux’ means a design value of the luminous flux of a replaceable light source or light source module.
6. The luminous flux of this gas-discharge light source may differ from the objective luminous flux specified in Regulation No 99.
7. Maximum rated power (Pmax) for a given rated luminous flux (Φ) (W) Clear lamps
8. Maximum rated power (Pmax) for a given rated luminous flux (Φ) (W)
9. Ignite the gas burner; the flame shall be non-luminous and approximately 4-5 cm high;
10. In this case, the luminous intensity values shall be corrected accordingly.
11. Multialkali photocathodes (e.g., S-20 and S-25) having a luminous sensitivity exceeding 350 µA/lm;
12. ‘Luminous efficacy of a source’, ‘light source efficacy’ or ‘lamp efficacy’ (ηsource), which means the quotient of the luminous flux emitted (Ф) by the power consumed by the source (Psource). ηsource = Ф / Psource. Unit: lm/W.
13. ‘Lamp Lumen Maintenance Factor’ (LLMF), which means the ratio of the luminous flux emitted by the lamp at a given time in its life to the initial luminous flux.
14. The maximum rated power (Pmax) for a given rated luminous flux (Φ) is provided in Table 1.
15. Number 30 indicates that the maximum luminous intensity of the driving beam is between 86250 and 101250 candelas.
