LED lights items frequently utilized specifications, such as illumination, wavelength, shade temperature and so forth, as criteria to determine the pros and cons. advantages and disadvantages. Below to describe most of those that acquire LED lights items under the typical specifications that tell you how to pick LED lighting items.
Understand the standard parameters of LED lighting items.
1. Luminaires power
Power is one of the most initial as well as typically made uses of specification in all appliances. It can just represent how much power the light can eat; now, it has come to be nearly the only sign aside from the light kind. When individuals talk about lamps and lanterns, they always state "15w light bulb", "120w street light," and so on, as well as a couple of people, state other signs. This is generally since the power specifications are easy to understand and approve. In the same series of lamps and lights, power and lamp performance are primarily proportional. Therefore, power rises to a comprehensive sign in everyone's mind instead of merely indicating how much power is eaten.
2. Luminescent change
Luminescent change is the fundamental indicator of light, which shows how much light energy is radiated from light source.
As the luminous change sign, there are typically two ways to mark: one is to mark the absolute worth. For instance, 15W with the luminous flux is 1500lm, which can be directly classified as 1500lm. Nonetheless, it does not mirror the output of these light energy consumed how much electric energy, a lot of lights and lights with the form of lm/ W to reflect the effectiveness of using electrical energy.
This kind of tag is called "luminescent effectiveness" indication. The luminescent efficiency of the downlight in the above instance can be shared as 100lm/w.
This is a loved one parameter; the bigger the value, the greater the use of electrical energy.
3, Luminaires color temperature and also shade making index
The significance of color temperature level, even more commonly referred to as the shade of the object at high temperatures. For instance, the temperature level after firing iron red is the color temperature level representing this color. As the temperature level increases, the color of the decision progressively ends up being yellow, white, blue. The shade temperature of high color temperature level is called high shade temperature level, generally refers to greater than 5000K, 3000K listed below the reddish color is called low color temperature level.
Allow's start with the color-providing index. It refers to the surface of the item is brightened by a specific light, the level of shade reproduction of the object being lit up. The shade temperature of noontime sunlight is 5500 to 6000 K. The color of items seen in the sunshine is considered natural. Hence, people specify the color providing an index of sunlight as 100.
The basic lighting setting does not need to pursue too high a color rendering index.
4. Luminaires distribution contour
The light from the resource is "totally free diffuse," for the most part, can not fulfill the requirements of the illumination effect. It is required to organize and also readjust these lights to make them work much better. This restriction and also the company of light is called "light circulation."
The light distribution curve can tell us the light effect of the lamp.
If a designer has the IES documents of the luminaire, he can determine the number of luminaires appropriate for space and make a detailed illumination plan for a room.
5. Luminaires power variable
Power factor is a important special to Luminaires. Because of the existence of the vehicle driver of the lamp or other accessories brought, the circuit will generate a huge amount of reactive current, which brings the loss of the whole light.
