【 Weak current College 】 LED lamp with common specifications terminology explained 】

Some lamps sales often received customer demand LED lamp with band of inquiry phone, but because of the LED lamp with band's specifications are not familiar with the terminology, it is often necessary to explain the half day to let the customers know. In response to this phenomenon, following the LED lamp with commonly used 5 specification terms explain and share, but also for purchasing friends refer to:

1. LED size:

0603, 0805, 1210, 5050 is the LED light strip on the use of light-emitting element--LED by size (inch/metric), the following is a detailed introduction to these specifications:

0603: conversion to metric is 1005, it means that the length is LED components, width is 0.5mm 1.0mm. Industry hereinafter referred to as 1005, inch crooner is 0603.

0805: conversion to metric is the 2125, it means that the length is LED components, width is 2.0mm 1.25mm. industry short 2125, inch crooner is 0805.

1210: conversion to metric is 3528, it means that the length is LED components, width is 2.8mm 3.5mm. Industry short 3528, inch crooner is 1210.

5050: this is the metric name, it means that the length is LED components, width is 5.0mm 5.0mm. Industry short 5050.

Second, LED lamp:

15, 30, 60 light refers to led lights with every metre length of the number of stars on welding LED components, generally 1210 specification lamp is 60 dual LED per meter, 5050 specifications lamp is bright LED 30 per metre, special has 60 single LED per meter. Different LED number of led lights with price is different, this is the case LED lamp with an important factor in the price.

3. color temperature:

Refers to a standard blackbody heating, temperature rise to a certain extent color started by Crimson-light red-orange-white-blue, gradually changing, a source of light and dark colors are the same, we will be at the absolute temperature blackbody is known as the light source of color temperature.

Generally speaking, the color temperature is not as examination LED light strip in an target, but many customers abroad because the relationship with the environment, will make a special request.

Light color, light color is different:

Color temperature in the following, light color 3300K partial red to warm feeling; staid atmosphere, warm feeling, known as the warm color temperature.

Color temperature 6000K in 3000--as intermediate, people in this tone without special psychological effects of Visual evident, readily feeling; it is called the neutral color temperature

Color temperature 6000K, light color over too blue, a cool feeling, known as cold color temperature.

Fourth, the brightness:

Cd (candela)

The basic unit of luminous intensity, the candela is the international system of units of one basic unit.

General LED lamps with different colors have different units of luminous intensity, in common, namely the mcd-candela. The higher the number, the larger the luminous intensity, that is, the more light. This is * fixed LED lamp brightness of important indicators of lamp brightness higher demands with expensive. This is because high-brightness led technology ' > chip prices expensive, and the higher brightness, package harder.

5. light-emitting angle:

This means the LED lamp with LED elements for beam angle, general common SMD LED SMD components, namely, the wide viewing angle is 120 degrees. Wide viewing angle, the greater the effect, the better since astigmatism, but relative, its glow brightness is reduced accordingly. Wide viewing angle, small, light intensity is up, but the exposure range will shrink the school as a result, * fixed LED light strip, another important indicator is the beam angle. Now there are some unscrupulous manufacturers, in order to increase the brightness of a luminescence to earn higher profits, decreasing intentionally wide viewing angle, slightly careless, would buy such a shoddy components.

6. voltage:

This means the LED light strip of input voltage, general common specifications are DC 12V or 24V with is.
