Introduction LED strip specifications

A, LED Size: 0603,0805,1210,5050 refers LED strip use light-emitting components bring - LED 's size ( inch / metric ) ,

        The following is a detailed description of these specifications :

0603 : conversion to metric is 1005 , it means that the length of the LED assembly is 1.0mm, the width is 0.5mm. Industry referred to 1005 , it is called Inch 0603 .

0805 : conversion to metric is 2125 , it means that the length of the LED assembly is 2.0mm, the width is 1.25mm. Industry referred to 2125, it is called Inch 0805 .

1210 : conversion to metric is 3528 , it means that the length of the LED assembly is 3.5mm, the width is 2.8mm. Industry referred to 3528 , it is called Inch 1210 .

5050 : This is a metric called, it means that the length of the LED assembly is 5.0mm, the width is 5.0mm. Industry referred to 5050 .

Second, LED lights: 15 lights, 30 lights , 60 LED lights, LED strip is per meter length of the number of pieces of LED components soldered , generally 1210 specifications lights per meter 60 LED, 5050 Specification lights per m 30 LED, there is a special per meter 60 LED. Different number of LED strip prices are different , and this is the price of LED strip distinction is an important factor .

Third, the color temperature : refers to a standard blackbody heating, the temperature rises to a certain extent, starting from the dark red color - light red - orange - white - blue , gradually changing the color of a black body light source and the same , then we will blackbody the absolute temperature is called the color temperature of the light source . Color is not a general assessment of LED strip an indicator , but many foreign customers because the use of the environment, will make a special request . Different color temperature light source , the light color is also different :

Color temperature below 3300K , the light red color cast give a warm feeling ; has solid atmosphere , warm feeling , known as Warm .

Color temperature 3000-6000K is the middle man in this particular hue under no obvious visual psychological effects, there is a refreshing feeling ; so called "neutral" color temperature.

Color temperature exceeds 6000K, light color blue , gives a cool feeling, known as cold color temperature.

Fourth, Brightness : cd ( candela )

The basic unit of luminous intensity , candela is the basic unit of the International System of Units one .

General LED strip different colors have different luminous intensity , commonly used unit is mcd, ie milli candela . The higher the value , the larger the light-emitting intensity , which is brighter. This is the assessment of the brightness of LED lights with important indicator lights with higher brightness requirements more expensive price . This is because the high-brightness LED chip prices expensive , and the brightness is higher, the greater the difficulty package .

Five. Angle:

This refers to the LED strip emitting angle to bring LED components , general use SMD LED, SMD components that are emitting angle of 120 degrees . Emitting angle increases, since astigmatism better, but relative, whose luminous intensity was correspondingly reduced. Viewing angle is small, light intensity is up, but the exposure range will shrink. Therefore, the assessment of LED lights with another important indicator is the light angle . There are now some unscrupulous manufacturers, in order to improve the brightness of light in order to earn higher profits, deliberately light angle decreases, the slightest mistake , they will buy such shoddy components.

Six , voltage: This refers to the input voltage LED strip , commonly used specification is a DC 12V, also some 24V.
