Take you a comprehensive understanding of common specification terms for LED lights
LED ceiling lights take you to a comprehensive understanding of common specifications and terms of LED lights
1. LED size: 0603, 0805, 1210, 5050 refer to the light-emitting element used on the LED light strip-the size of the LED (English/Metric), the following is a detailed introduction of these specifications:
0603: Converted to metric system 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 English system is called 0603.
0805: Converted to the metric system is 2125, which means that the length of the LED component is 2.0mm and the width is 1.25mm. The industry abbreviation is 2125, and the British system is called 0805.
1210: Converted to metric system 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 English name is 1210.
5050: This is called the metric system, which means that the length of the LED component is 5.0mm and the width is 5.0mm. The industry abbreviation is 5050.
2. Number of LED lights: 15 lights, 30 lights, 60 lights refer to how many LED components are welded per meter length of the LED light strip. Generally speaking, the 1210 specification light strip is 60 LEDs per meter, and the 5050 specification light strip is per meter. There are 30 LEDs per meter, especially 60 LEDs per meter. The price of LED strips with different LED quantities is different, which is also an important factor to distinguish the price of LED strips.
3. Color temperature: refers to heating a standard black body. When the temperature rises to a certain level, the color starts to change from deep red-light red-orange-white-blue. When the color of a light source and the black body are the same, we will use the black body at that time The absolute temperature of is called the color temperature of the light source.
Generally speaking, color temperature is not used as an indicator for evaluating LED light strips, but many foreign customers will make a special requirement due to the use environment.
The color temperature of the light source is different, and the light color is also different:
The color temperature is below 3300K, the light color is reddish to give a warm feeling; there is a stable atmosphere, a warm feeling. It is commonly called warm color temperature.
? The color temperature is in the middle of 3000-6000K, and people have no particularly obvious visual psychological effects in this hue, and there is a refreshing feeling; therefore, it is called "neutral" color temperature
? The color temperature exceeds 6000K, and the light color is bluish, giving people a cool feeling, commonly known as cool color temperature.
4. 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 lights have different luminous intensities, and the common unit is mcd, which 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 strips. The higher the brightness requirements, the more expensive the strips. This is because high-brightness LED chips are more expensive, and the higher the brightness, the greater the difficulty of packaging.
5. Light-emitting angle:
This refers to the light-emitting angle of the LED components on the LED strip. Generally, the light-emitting angle of the general-purpose SMD LED, that is, the SMD component, is 120 degrees. The larger the light-emitting angle, the better the astigmatism effect, but the relative brightness of the light is also reduced. The light-emitting angle is small, the intensity of the light is up, but the range of illumination will be reduced. Therefore, another important indicator for evaluating LED strips is the light-emitting angle. Nowadays, there are some bad manufacturers on the market. In order to increase the brightness of the light to make higher profits, they deliberately reduce the angle of light. If they are not careful, they will buy such shoddy components.
6. Voltage: This refers to the input voltage of the LED strip. The commonly used specification is DC 12V, and some are 24V.
