To create acceptable conditions of work you want to pick a ceiling lamp in accordance with the requirements. Some of them
If the requirements for light sources are satisfied with the lighting in the office will not create discomfort or impact on the health and working capacity of employees.
The first thing to pay attention to a number of technical characteristics supply voltage 220230В operating temperature for offices is somewhat different than for street counterparts +5+35 degree energy efficiency class which is important in long-term operation of A+ degree of protection for premises with normal humidity level enough IP20 IP23.
Taken into account and characteristics of light. This color temperature luminous flux shall be determined in accordance with the requirements of the led type.
It is also important to take into account structural features. The main one is the mounting method. Ceiling lighting fixture should be chosen based on the fact on what surface you plan to install.
For suspended structures there are special varieties of lamps. The housing may be made of steelaluminum.
Another important parameter is the color rendering index CRI. If this figure is below the sufficient level to use the manufacturer vinovnyh LEDs. As a result, the lamps emit non-uniform light which causes fatigue headaches and more.
In addition you need to take into account the optical system of the device type of the lens its design material and degree of transparency. Mostly it concerns point performances chandeliers and pendant option as they are represented by many different models. But overhead ultrathin and embedded analogs differ standard design.
On hearing has long been information on what led lighting products are characterized by a minimum level of energy consumption thus reducing electricity costs. In the long at least 8-10 CST. this is especially important.
To determine whether office lighting devices based on diodes are energy efficient, you must compare them with characteristics similar to light analogues of a fluorescent lamp.
For example, would be considered two types of luminaires LVO 12-4h18 and DVO 12-02-43. The second variant is equipped with led emitters. Power consumption of both designs differs markedly 72w fluorescent and diode 43.
In this case the luminous flux of the latter is higher: 700 LM 4 in contrast to 3 500 LM fluorescent counterparts. Accordingly, the luminous efficiency of the diode light sources is 109 Lmwt fluorescent 48 Lngt.
The ROI of LPO and LED lamps
To determine the degree of saving will be considered an example of an area of 200 sq. m. with a light level of 300 Lux. In the case of luminous performances need 10 lights to provide a working environment if we consider the diode equivalents is enough 8 PCs. of devices.
In the end, the calculation showed that the electricity consumption during the day 10 hours during the operation of led devices is 344 kWh is multiplied by the power of a single lamp on their total number.
Accordingly, the annual consumption of energy in this case will be lower and savings will be 958 kWh excluding weekend days which is almost two times less than when using fluorescent analogues.
The cost of electricity is constantly changing so to determine the degree of efficiency in the expenditure need for each specific case. But overall, it is clear that led lamps for offices are more preferred due to the confirmed efficiency. So it is possible to speak of a relatively quick payback of lighting devices of this type.
Despite the large number of advantages of using diode light sources, like UV radiation and flickering still there are some shortcomings which influence the level of comfort and well-being of employees
Otherwise, the diode ceiling lights are not satisfactory. Only need to control the brightness level of the light flux as close to the end of life there was a marked decrease of luminescence intensity due to natural processes.
The regulations specify different levels of illumination for rooms of various purposes
Thus diode lighting apparatus for installation on the ceiling, chandeliers hanging overhead and performance. differ in a considerable number of major advantages. If earlier at purchase stopped the price of such products today they are offered at a more affordable cost due to the expanded scope of their use and popularity.
One of the advantages of a large number of designs that allows you to embed lights in suspended ceilings to create different combinations of lighting using dot devices.
