Description of Luminaire Types

 
    For implementation of design solutions R&P Enterprise VTN introduces the development of LED luminaires with division into the following types:
 
А – Luminaires of general use. This type is the most common. Popular models of «А» type are always available at the warehouse and at production for prompt shipments to the clients.
 
В – Luminaires with higher protection rating. These models have water spray and dust protection. They can be used in damp rooms, warehouses and outdoor patios. Models of «В» type are available to order with the lead-time 14 work days.
 
С – Luminaires with compensation of LED's degradation in the course of time. The models of this range take account of luminaire operation time since its manufacturing and adjust luminous flux value.
 
O – Luminaires of «O» type maintain the control of luminous flux level according to 0-10 V control interface. The control is carried out using only 2 additional conductors that can be simultaneously connected to many luminaires. To use the 0-10 V interface, it is sufficient to install the relevant regulator or potentiometer. If the control signal is absent, the luminaire operates with nominal brightness.
 
D – Luminaires with brightness and color temperature control functions. These luminaires are easily to install in rooms, creating the most comfortable working environment and implementing the electricity saving and illumination maintenance scenarios. Models of «D» type are produced with DALI regulation function.
 

Е – Luminaires of «Е» type are produced using Samsung LEDs (not Osram, like all other types). This type has lower energy efficiency (125-130 lm/ W, not 140 lm/W like all other types) and a significantly lower price. «Е» type is recommended for cost savings (payback period in the short term). Its use is economically feasible in the areas where the usage time makes up less than 8 hour per day.
For reference: standard LED-panels have the energy efficiency of 70-80 lm/W.

K – Luminaires with adaptive luminous flux. Luminaires of this series maintain illumination control in the zone of their direction diagram regulating their own luminous flux and input power automatically according to redundant background illumination by other light sources. The regulative function is autonomous for each luminaire.
 
P – Luminaires of reserve lighting with the transfer function into low power mode in case of power failure, when constant voltage 50 V is supplied from emergency power unit. Some models also have internal battery and keep operating from the own power supply with lower power in case of power failure.
