LED lighting main parameters and description

There are many parameters of LED lamps. Due to the different lighting application, the focus of the indicators will be different. It is difficult to say that which indicators are absolutely important, and which indicators are definitely not important. For general lighting, the most common ones are wattage, luminous flux, and color temperature. For professional lighting, such as road lighting and car lighting, we must pay more attention on light distribution curve and color temperature; production line lighting we must pay attention to color rendering index; large-area installation of high-power lamps we must pay attention to power factor, etc. The following is a brief introduction to these parameters:

1)Power (W)

Power refers to the amount of work done by an object in a unit time, that is, power is a physical quantity that describes the speed of work. Represents how much electricity the lamp can consume.

2) Luminous flux (LM)

Luminous flux is the basic indicator of a light source, it indicates how much light energy the light source radiates outward

3)Luminous efficiency (LM/W):

It is the ratio of the luminous flux emitted by an electric light source to its electricity consumption, and it is the most important technical parameter for evaluating the electricity efficiency of an electric light source. LEDs with high luminous efficiency can get the same brightness with less electric energy. LIGHT VICTOR LED tube light efficiency can be high up to 180lm/w and panel lights be 170lm/w.

4) Color temperature (K)

Color temperature is a measure that represents the color of light emitted by a light source, and is a value that represents the color of light. When a black body is heated to a temperature and the light color of the body emitted is the same as the light emitted by a light source, the heated temperature of the black body is regarded as the color temperature of the light source. Falling on the black body radiation line (Planck curve)

5) Color rendering index (Ra)

Color rendering is the degree of light restores the true color of an object. The color rendering index (Ra) is usually used to indicate the color rendering performance of the light source. The higher the color rendering index of the light source, the better the color rendering performance.

6) Power factor

A coefficient that measures the efficiency of electrical equipment. High power factor means high effective utilization of electric energy and low grid load; low power factor means that the circuit uses high reactive power for alternating magnetic field conversion, which reduces equipment utilization and increases line power supply losses.

7)Lamp lifespan (H)

Effective life: the time when the lamp can't work (no light/no start/color failure)

Economic life: the lighting time from the beginning of use to the luminous flux attenuation (ie luminous attenuation) to a certain percentage of the initial rated luminous flux (70% outdoors, 80% indoors)

Average life: the time from ignition to 50% (50% remaining intact) failure of a set of test sample lamps
