Definition:
Flexible Led strip refers to the strip of LED set mounted on FPC (flexible printed circuit board) (Attachment: Rigid Strip with PCB hard board), with SMD package high-brightness LED as light source, every three lights as a unit, will LED chip welding on the soft circuit board.
Components:
SMD flexible light strip waterproof divided into four :
Epoxy, waterproof casing, solid waterproof (U-groove + resin), filling plastic waterproof (casing + resin) Which conventional PU polyurethane with a high temperature resistance (tested in 40 ℃ -. -20 ℃, UV, folding, wear and other features)
Waterproof:
Not waterproof – bare board –IP00,
IP65 Epoxy waterproof,
IP67 silicone casing waterproof,
IP68-PVC tube filled waterproof (waterproof casing + Glue / half sleeve + Epoxy).Note: Epoxy glue is AB glue, the ratio was 1: 1,
casing material is silica gel (softness is good, for a long time will not yellowing, are not compatible with AB glue),
PVC (transparent, combination with AB glue, a long time will yellowing). Low pressure is to add a switching power supply, is a step-down rectification.
LED bead colors: red wavelength:620-625nm (nm)
yellow wavelength of 590~595nm
blue wavelength 475~480nm
green wavelength 520~525nm is cast beyond the above,
beyond the wavelength range is partial color,
white is usually defined by color temperature,
divided into: warm white color temperature 2700K-4000K (Kelvin) is white temperature 4000K-5000K cool white color temperature above 6000K.Divided into monochrome (white –5000K above,
warm white –2700K above, red, yellow, blue, green, pink, purple),
which is white, warm white, mostly blue followed.
There is a colorful (RGB) with the Symphony of the (plate than the IC,, there is flowing water effect, with digital effects like).
3.2.3, the brightness of brightness lamp beads with flux (lumens) lumen (LM) is defined, the higher the value, the higher the lumens brightness. There are several on the market now: 3528 (3-4LM, 4-5LM, 5-6LM, 7LM above) the first two are generally used for soft light strip, which is used for lamps, panel lights; 5050 (10 12LM, 12-15LM, 16-18LM) all of these can be used for flexible light strip, generally jewelry cabinet light bar that is hard for high brightness light bar is generally used 16-18LM’s.
Lamp specifications:
0603, 0805, 1210, 3528, 5050 refers to the LED size. size unit (inch / Metric), below are the details of these specifications: 0603: conversion to metric is 1005, which represents the length of LED components is 1.0mm, the width is 0.5mm. Industry referred to 1005, British, it is called 0603.
0805: conversion to metric is 2125, which represents the length of LED components is 2.0mm, the width is 1.25mm industry referred to 2125, British, it is called 0805.
1210: conversion to metric is 3528, that is represents the length of LED elements is 3.5mm, width is 2.8mm. Industry referred to 3528, British, it is called 1210.
3528: This metric is called, means that the length of the LED elements is 3.5mm, the width is 2.8mm, the industry referred 3528.
5050: This is also called the metric that indicates the length of the LED elements are 5.0mm, width is 5.0mm, the industry referred to as 5050. Most manufacturers of SMD lights are used mostly in 3528 and 5050,
