LED decoration lights according to the luminous surface characteristics of the classification of the features?
Jan 31, 2018

LED decoration lights according to the luminous surface characteristics of the classification of the features:

LED decoration lights, according to the luminous surface characteristics of the circular lamp, square lamp, rectangle, surface light tube, side tube, surface installation of micro tube, and so on. The circular lamp is divided into 2mm, 4.4mm, Phi 5mm, Phi 8mm, Phi 10mm and phi 20mm according to the diameter. In foreign countries, the 3mm is usually recorded as T-1; the phi 5mm is recorded as T-1 (3/4); and 4.4mm is recorded as T-1 (1/4).

The angular distribution of the circular luminescence intensity can be estimated by the size of the half value angle of LE.


The LED decoration lights is divided into three categories from the angular distribution of the luminescence intensity:

(1)High directivity. Generally, it is a pointed epoxy package, or a metal reflector, without a scattering agent. The half value angle is 5 to 20 degrees or smaller. It has very high directivity. It can be used as a local lighting source, or combined with a light detector to form an automatic detection system.

(2)Standard type. It is usually used as a indicator, with a half value angle of 20 to 45 degrees.

(3)Scattering type. This is a large indicator light with a half value angle of 45 to 90 degrees or more, and the amount of the scatters is larger.
