Which parameters should be considered when choosing LED lights?

February 28, 2023


  In the past, when discussing LED lighting applications, most of the application scenarios were in the fields of smart homes, offices, and cars. However, as these markets become saturated, LED lighting has entered the industrial field with a higher threshold. LED lamps are very different from traditional lamps in performance, especially LED lamps used in industrial lighting. So how do users choose good and suitable LED lights for industrial lighting when purchasing? The following is a brief introduction to several parameters of LED lights for industrial lighting.

 1. Illumination

Industrial lighting should ensure the comfort and safety of workers under the condition of reaching a certain illuminance. Reasonable lighting can balance the lighting level of the entire ground area and working surface.

2. Brightness

The brightness of LED lights is the most concerned issue for users, and the brightness can be explained from two aspects.

Luminance L: The luminous flux of the illuminant in a unit solid angle and unit area in a specific direction. Unit: Nitrate (cd/㎡).

Luminous flux φ: the sum of the amount of light emitted by the luminous body per second. Unit: Lumen (Lm), which indicates how much the luminous body emits light, and the more light is emitted, the greater the lumen.

Usually LED lights are marked with luminous flux, and users can judge the brightness of LED lights according to the luminous flux. The higher the luminous flux, the higher the brightness of the lamp.


3. Color temperature

Color temperature is a unit of measurement to identify the color of light, expressed in K value. Yellow light is "below 3300k", white light is "above 5300k", and there is an intermediate color "3300k-5300k".

Of course, users can choose a suitable color temperature according to the environment of the lighting application and the needs of the workers.

4. Leakage current

LED is a unidirectional conductive illuminant. If there is a reverse current, it is called leakage. LED with large leakage current has a short life.


5. Antistatic ability

LEDs with strong antistatic ability have long life and high price. Many counterfeit and shoddy products on the market do very poorly in this regard, which is also the root cause of the greatly shortened life expectancy.


6. Life expectancy

The key to different qualities is life, which is determined by light decay.

Low light decay, long life, the real quality LED lights have almost no light decay, this is the top level in the industry, most of the LED light manufacturers in the industry can not reach.


7. Protection level

IP is the abbreviation of Ingress and Protection. The IP level is the protection level against the intrusion of foreign objects by the electrical equipment shell, such as: explosion-proof electrical appliances, waterproof and dustproof electrical appliances, and the source is the standard IEC60529 of the International Electrotechnical Commission.

The protection level is mostly expressed by IP followed by two numbers, and the numbers are used to clarify the level of protection.

The first number indicates how far the device is resistant to fine dust, or how well people are protected from hazards in a sealed environment. Represents the level of protection against the entry of solid foreign objects, the highest level is 6.

The second number indicates how waterproof the device is. Represents the level of protection against water ingress, the highest level is 8.
