ARTICLE Calculating the amount of Lights & Electric Power In A Room READ NOW

Optimization of Electricity .

Power calculation is influenced by several factors, such as function space ( to determine the bright lights ), the type of light ( affects the amount of light emitted ), and the number of armature / point of light (so that the light distribution is more equitable and as needed). Electric power installed must not exceed the maximum number specified for each space .

• Example calculation:

Spacious dining room: 5 m x 4 m = 20 m2. Light power: 3 pieces (light point) x 15 watts = 45 watts. Power: living space = 45: 20 = 2, 25 watt / m2 (qualify).

• Determine the position of the lights.

These calculations use the lights used numbers fit with the needs. If less or redundant, in addition to extravagant, also cause discomfort in the eyes.

Example: Using a downlight that has a light angle of 30 °.

1. Calculate high ceiling heights and areas of work from the top floor. For example, the ceiling height of 3 meters and 80 cm working field. What is meant by work area is an area that is most widely used for activities in space page. In the study, for example, read and write activity on the table, is the most frequently performed. Table height will be, will be a high benchmark areas of work. After that the Pythagorean formula you can calculate the distance between the point of light in these space.
2. Lumen is the amount of light produced by a lamp. Lumen is used as the unit of strong / bright light. The distance between the surface of the table with the armature chandelier is not more than 75 cm. Distances cause greater heat emitted light will be felt when people would stand. The ideal distance between the point of lighting the lamp (ceiling) to the floor is 2.5 meters. Lights placed at any height, keep these distances are met, so that the received light bulbs space is not reduced.

• Calculating the amount of light & power

Formula Number of Lights
The amount of light in a determined space / can be calculated with the following formula:
N = E x L x W/(Ø x LLF x CU x n)
Where :
N = the number of light points
E = Strong Lighting / strong targets lighting will be achieved (Lux)
L = Length Space (Meters)
W = Width Space (Meters)
Ø = Total Lumen Lamp / Lamp Luminous Flux
LLF = Light loss factor / Light Loss Factor (0.7-0.8)
CU = Coeffesien of utilization / utilization factor (50-65%)
n = number of lamps within one point of Lights

STRONG LIGHTING (E)
Office = 200-500 Lux
The apartment / house = 100-250 Lux
Living Room = 50-100 Lux
Family room = 50-100 Lux
Place Read = 200 Lux
Dining Room = 100-200 Lux
Bedroom = 20-50 Lux
The lobby / Hall = 25-50 Lux
Hotel = 200-400 Lux
Hospital / School = 200-800 Lux
Basement / Toilet / Coridor Hall / Warehouse / Lobby = 100 - 200Lux
Restaurant / Store / Shop = 200-500 Lux

Electrical power formula
Ø = W x L / w
Where :
W = power lights,
L / w = Luminous Efficacy Lamp / Lumen per watt (can be seen in the light box which we bought).

Sample case
Point number of lights to be installed in the room 7 x 4 meters using 18 W PL lamp types (ESSENTIAL 18W CDL E27 220-240V)
The solution:
N = E x L x W/(Ø x LLF x CU x n)

N = 150 x 7 x 4/(1098 x 0.8 x 65% x 1)
N = 4200/570.96
= 7.36 = 8 Point Lights

According to standard ISO, for lighting the house does not exceed 10 W / M², then:
Total W / M2 = number of points x watt light bulbs

Spacious room
Amount W / M2 = 8 x 18/(7 x 4)
Amount W / M2 = 5.14 w / m2

From the above calculation, we know that with a 7x4 meter room which will be fitted with a type PL lamp 18W 18W CDL E27 220-240V ESSENTIAL requires at least 8 point lights. If the result of the above calculation is too bright or too dim, we can get around to replace the lamp with a higher wattage or lower.
