5 common specification terms for LED panel lights
We often receive inquiries from customers for LED panel lights, but because we are not familiar with the specifications and terms of LED panel lights, we often need to explain to customers for a long time before they can understand. In response to this phenomenon, the following is an explanation and sharing of the 5 commonly used specifications and terms of LED panel lights, which are also for the reference of purchasing friends:
LED size:
1. 0603, 0805, 1210, 5050 refer to the light-emitting element used on the LED panel light----the size of the LED (imperial/metric), the following is a detailed introduction of these specifications:
a. 0603: Converted to metric, it is 1005, which means that the length of the LED element is 1.0mm and the width is 0.5mm. The industry abbreviation is 1005, and the imperial name is 0603.
b. 0805: Converted to metric system, it is 2125, which means that the length of the LED element is 2.0mm and the width is 1.25mm. The industry abbreviation is 2125, and the imperial name is 0805.
c. 1210: Converted to metric, it is 3528, which means that the length of the LED element is 3.5mm and the width is 2.8mm. The industry abbreviation is 3528, and the imperial name is 1210.
d. 5050: This is the metric name, which means that the length of the LED element is 5.0mm and the width is 5.0mm. The industry is referred to as 5050.
Number of LED lights:
15 lights, 30 lights, and 60 lights refer to how many LED components are welded per meter length of the LED panel light. Generally speaking, the 1210 specification light strip is 60 LEDs per meter, and the 5050 specification light strip is 30 LEDs per meter. of 60 LEDs per meter. The price of LED panel lights with different numbers of LEDs is different, which is also an important factor to distinguish the price of LED panel lights.
Color temperature:
1. Color temperature refers to heating a standard black body. When the temperature rises to a certain level, the color starts to change from dark red - light red - orange yellow - white - blue, and gradually changes. The absolute temperature is called the color temperature of the light source. Generally speaking, color temperature is not an indicator for evaluating LED panel lights, but many foreign customers will make a special request due to the use environment.
2. The color temperature of the light source is different, and the color of the light is also different:
a. The color temperature is below 3300K, and the light color is reddish to give a warm feeling; there is a stable atmosphere and a warm feeling. Commonly known as warm color temperature.
b. The color temperature is in the middle of 3000--6000K, people have no obvious visual psychological effect under this color tone, and have a refreshing feeling; so it is called "neutral" color temperature
c. The color temperature is over 6000K, and the light color is bluish, giving people a cool feeling, commonly known as cold color temperature.
Brightness: cd (candela)
The basic unit of luminous intensity, candela is one of the basic units of the International System of Units. Generally, different colors of LED panel lights will have different luminous intensities. The common unit is mcd, that is, millicandela. The higher the value, the greater the luminous intensity, that is, the brighter. This is an important indicator for evaluating the brightness of LED panel lights. The higher the brightness requirements, the more expensive the light strips are. This is because high-brightness LED chips are expensive, and the higher the brightness, the more difficult it is to package.
Beam angle:
This refers to the light-emitting angle of the LED components on the LED panel light. Generally, the general-purpose SMD LED, that is, the light-emitting angle of SMD components, is 120 degrees. The larger the light-emitting angle, the better the astigmatism effect, but the brightness of the light is correspondingly reduced. When the light-emitting angle is small, the intensity of the light increases, but the range of illumination will be reduced. Therefore, another important indicator for evaluating LED panel lights is the luminous angle. There are some bad manufacturers on the market. In order to increase the brightness of the light to earn higher profits, they deliberately reduce the light-emitting angle. If you are not careful, you will buy such shoddy components.
Voltage:
This refers to the input voltage of the LED panel light. The commonly used specification is DC 12V, and some are 24V.
