Led Strip specifications and technical parameters
The light-emitting element used on the light bar-the size of the LED (imperial/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.
3528: This is the metric system, which means that the length of the LED component is 3.5mm, the width is 2.8mm, and the industry abbreviation is 3528.
5050: This is also called the metric system, which means that the length of the LED component is 5.0mm, the width is 5.0mm, and the industry abbreviation is 5050.
Most of the SMD-type light bars produced by manufacturers use 3528 and 5050, which are waterproof and non-waterproof according to requirements. The packaging is mostly a roll every 5 meters.
This refers to the input voltage of the LED light bar. The commonly used specification is DC 12V, and some are 24V. Working voltage: DC12V power: 14.3 watts per meter / 18.2 watts per meter, optional.
2. Color temperature:
It 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-white-blue, and gradually changes. When a light source is the same color as the black body, we call the absolute temperature of the black body at that time Is 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, and the light color is reddish to give a warm feeling; it has a stable atmosphere and a warm feeling, commonly known as warm color temperature.
The color temperature is in the middle of 5000-6000K, and people have no particularly obvious visual psychological effects under this hue, and there is a refreshing feeling; therefore, it is called "neutral" color temperature.
The color temperature is more than 6000K, and the light color is bluish, giving people a cool feeling. It is generally called cold color temperature.
Under normal circumstances, 7500K (cool white to blue)/6500K (normal white)/3500K (warm white to yellow).
The basic unit of luminous intensity, candela is one of the basic units of the International System of Units.
Generally, different colors of LED light bars 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 light bars. The higher the brightness requirements, the more expensive the light bar. This is because high-brightness LED chips are more expensive, and the higher the brightness, the greater the difficulty of packaging.
4. Beam angle:
This refers to the light-emitting angle of the LED components on the LED light bar. Generally, the light-emitting angle of the general-purpose SMD LED (ie 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 light bars is the luminous angle. There are some bad manufacturers on the market, in order to increase the brightness of the light to make higher profits, deliberately reduce the angle of light, a little careless, they will buy such shoddy components.
