Buy LED light group tips

May 23, 2023

In the early stage of the development of LED lamps, the price was high due to multiple product features. Ordinary incandescent lamps are very cheap, and ordinary people have a transition period for the price gap. Therefore, in the early days, it was mainly used for commercial, market, and street.

With the continuous improvement and wide application of LED technology, people's pursuit of sensory vision of LED lamps is further improved, and higher requirements are placed on product performance and product design. This requires our LED industry manufacturers and end product designers to update the standard dynamics.

Choose different parameters to tailor the "custom" light group

Nowadays, all aspects of society have involved the application of LED lamps, ranging from shopping malls to audio-visual entertainment. From brand concept to product itself, it has attracted the attention of all walks of life, but due to the class of lamp groups. The variety is numerous and the quality is relatively uneven. In this way, choosing a model suitable for its own use according to the different parameters of the luminaire has become a topic of great concern to the buyers.

Common parameters of LED lighting products, such as brightness, wavelength, color temperature, etc., as a standard for distinguishing between good and bad. The following is a description of the common parameters of LED lighting products for the majority of buyers, tell you how to buy LED lighting products.

1, brightness

LED light brightness includes:

Luminance L: Luminous flux of the illuminant in a unit area of a solid angle unit in a specific direction. Unit: Nitta (cd/m2).

Luminous flux φ: the sum of the amount of light emitted by the illuminator per second. Unit: Lumen (Lm), which indicates how much the illuminant emits light, and the more the illuminance, the larger the lumen number.

Then: the larger the lumen number, the more the luminous flux, the higher the brightness of the lamp.

2, wavelength

LEDs with the same wavelength have the same color. It is difficult for manufacturers without LED spectrophotometers to produce pure color products.

3, color temperature

Color temperature is a unit of measure that identifies the color of a light and is expressed as a K value. The yellow light is "below 3300k", the white light is "5300k or more", and the intermediate color is "3300k-5300k". Customers can choose the right color temperature source according to their personal preferences, application environment and lighting effects and atmosphere.

4, leakage current

The LED is a unidirectional conductive illuminator. If there is a reverse current, it is called leakage, and the LED with a large leakage current has a short life.

5, antistatic ability

LEDs with strong antistatic properties have a long life and are therefore expensive. Generally, LEDs with an antistatic greater than 700V can be used for LED lighting (lighting decoration renderings).

6, life

The key to different qualities is life, and life is determined by light decay. Low light decay and long life.

7, design

Each product will have different designs. Different designs are suitable for different purposes. The reliability design of LED lighting includes: electrical safety, fire safety, environmental safety, mechanical safety, health and safety, and safe use time.

8, energy identification

The energy label is to provide consumers with information on energy consumption and benefits, and to facilitate consumers to purchase high-performance products.

EU energy symbol

The EU divides the energy efficiency of products into 7 levels, and the products with A grade have the highest energy efficiency and the G grade is the lowest.
