The type of LED lights

Date:21-08-2017

    Energy is a valuable resource, so saving energy is a daunting problem facing us in the future. LED is a new type of energy-saving, environmentally friendly green light source products. In this, the author with everyone to understand LED lights. This article is to give everyone the LED classification. The same time as
   1. Sort by the luminous color of the luminous tube
According to the luminous color of light, can be divided into red, orange, green (and subdivided yellow green, standard green and pure green), blue and so on. In addition, some light-emitting diodes contain two or three colors of the chip. According to the light-emitting diode light or not mixed with scattered scattering, colored or colorless, the various colors of light-emitting diodes can be divided into colored transparent, colorless and transparent, colored scattering and colorless scattering four types. Scattering light-emitting diodes and up to do with the indicator light. The same time as
   2. According to the luminous tube out of the characteristics of light classification
According to the luminous tube out of the smooth characteristics of sub-round lights, square lamps, rectangular, surface luminous tube, lateral tube, surface mount micro-tube. The same time as
Round lights according to the diameter is divided into φ2mm, φ4.4mm, φ5mm, φ8mm, φ10mm and φ20mm and so on. Foreign φ3mm light-emitting diodes are usually referred to as T-1; φ5mm recorded as T-1 (3/4); φ4.4mm recorded as T-1 (1/4). The angular distribution of circular luminous intensity can be estimated from the half-value angle. From the luminous intensity angle distribution points, specifically the following three categories:
   (1) high directivity. Generally in a pointed epoxy package, or with a metal reflective cavity package, without the addition of scattering agent. Half angle of 5 ° ~ 20 ° or less, with a high directivity, can be used for local lighting, or with the photodetector in order to form an automatic detection system. The same time as
   (2) Standard type. Usually for the indicator light, the half-value angle of 20 ° ~ 45 °. The same time as
   (3) Scattering type. This is a large angle of view of the light, half-value angle of 45 ° ~ 90 ° or more, the amount of scattering agent. The same time as
   3. According to the structure of light-emitting diodes according to the structure of the light-emitting diode is divided into epoxy encapsulation, metal base epoxy packaging, ceramic base epoxy packaging and glass packaging and other structures. The same time as
   4. (Luminous intensity> 10mcd); ultra-high brightness LED (luminous intensity> 100mcd); the luminous intensity between 10 ~ 100mcd called between the high brightness (light intensity <10mcd); luminous intensity and operating current classification according to the luminous intensity and operating current divided into ordinary brightness LED (luminous intensity <10mcd) led. General LED operating current in more than ten mA to several tens of mA, while the low current LED operating current below 2mA (brightness and ordinary light tube the same).
   In addition, LED lights products have the following categories:
(1). LED lights with
(2). LED ceiling light
(3). LED fluorescent lamp
(4). LED bulb lights
(5). LED decorative lights
(6). LED corn lamp
(7). LED spotlights
(8). LED lights cups
   In addition to the above classification method, there are classified and classified according to the chip material.
