LED lights with common specifications Explanation of terms


Some lighting sales often receive customer LED "> LED lamp with telephone inquiry, but because of the LED lights are not familiar with the specifications of the term is often necessary to explain to the customer half a day to let customers know. In response to this phenomenon, the following put the LED lights with 5 specifications commonly used to explain and share what terminology, but also for the purchase of friends as a reference:

A, LED Size: 0603,0805,1210,5050 is put to use LED lights ---- LED lighting device the size (inch / metric), the following detailed description of these specifications:

0603: conversion to metric is 1005, that means the length of LED components 1.0mm, width 0.5mm. Industry referred to as 1005, English name for 0603.
0805: conversion to metric is 2125, that means the length of LED components 2.0mm, width 1.25mm. The industry referred to as 2125, English it is called 0805.
1210: conversion to metric is 3528, that means the length of LED components 3.5mm, width 2.8mm. Industry referred to as 3528, English it is called 1210.
5050: This is the metric it is called, means that the length of LED components is 5.0mm, width 5.0mm. Industry referred to 5050.

Second, LED light: 15 lights, 30 lights, 60 LED lights with light is on per meter length of the number of pieces welded LED components, in general, is the 1210 standard lamp with 60 per meter, LED, 5050 size with every light m 30 LED, a special 60 per meter LED. Different number of LED lights with LED price is different, which is distinguished with the price of LED lights is an important factor.

Third, the color temperature: refers to a standard black body heated to a certain degree temperature started by the dark red color - light red - orange - white - blue, gradually changing the color of a light source and the same bold, we will be bold when the absolute temperature as the light source color temperature.

LED color temperature is not as a general assessment with an indicator light, but many foreign customers since the use of the environment, will make a special request.

Different color temperature light source, light colors are also different:

Following in the 3300K color temperature, light red color cast give a warm feeling; a stable atmosphere, warm feeling., Known as warm temperature.
Color temperature 3000 - 6000K for the middle, not in this tone was particularly evident under visual psychological effects, there are refreshing feeling; so called "neutral" color temperature
Color temperature more than 6000K, bluish light color, giving the feeling of cold, known as the 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 lights with different colors have different luminous intensity, common units are mcd, the Candela cents. The higher the value, indicating that the greater the light intensity, that is, the more light. This is the assessment of LED lights with an important indicator of the brightness, the brightness of the lamp with the higher prices required the more expensive. This is because the high-brightness LED chips price of your side, and the higher the brightness, the greater the difficulty of packaging.

V. Beam Angle:

This is the LED light to bring light-emitting LED elements angle patch for general LED, SMD components that are emitting angle of 120 degrees. Emitting angle increases, the better from astigmatism, but the relative brightness of its light was correspondingly reduced. Viewing angle is small, the intensity is up, but will reduce the range of exposure. Therefore, the assessment of LED lights with light-emitting another important indicator is the point of view. There are now some unscrupulous manufacturers, in order to improve the brightness of light in order to earn higher profits, deliberately light-emitting angle decreases, the slightest mistake, they will buy such a shoddy components.

VI, voltage: This refers to the input voltage with LED lights, commonly used specification is DC 12V, but also plenty of 24V.
