LED strip designs are available populated with many different types of SMD, not only in different colors and addressable or non-addressable, by different shapes, sizes, and power levels. RGBCCT or RGBWW: The combination of dynamic tunable white and multicolor (5 LED-chips) in a single module.RGBW, non-addressable: The combination of single color and multicolor (4 LED-chips) in a single module.Each LED has its own chip meaning they can be individually triggered for chasing, strobing, and colour changing. RGB, addressable: Multiple colours and addresses.All the LEDs display the same colour at any one time, but the colour can be manipulated by varying the voltage applied to each of the three power inputs. Multicolor, non-addressable: Each LED is capable of displaying red, green, blue, or all three (white), driven by three input power rails.They are manufactured with alternating LEDs of different color temperatures, so half of the LEDs are a lower temperature and half are a higher color temperature, allowing the strip to produce any specific color temperature between the two color temperatures of the LEDs. Dynamic tunable white (often described with CCT), non-addressable: Allows the user to adjust the color temperature output from a single strip light.Single color, non-addressable: Every LED on the strand is a single white colour, typically ranging from 2200K to 6500K in color temperature, or any of several monochrome colors covering the range of the visible spectrum (generally from 400-700 nanometers in wavelength).The most common design differences are in how individual LEDs are controlled, specifically differences in color and whether or not each LED is addressable. Both coated and uncoated LED tapes have a two sided adhesive backing to stick to walls, desks, doors, etc. Water resistant strip lighting is covered in a heat conducting epoxy or silicone to protect the circuitry from direct contact with water, and can be rated IP65, IP67, or with suitable sealed connections IP68.

Such tapes are generally low voltage and safe for skin to touch but can be shorted by fine metal objects.

Uncoated LED tape is not considered to have any resistance to water ingress, but may be rated with an ingress protection code as IP20 for some physical ingress resistance. Variables in strip lighting consist of water resistance, color, adhesives, choice of SMD, driving voltage, control type, and whether it is constant current or constant voltage layout. Increased luminous efficacy and higher-power SMDs have allowed LED strip lights to be used in applications such as high brightness task lighting, fluorescent and halogen lighting fixture replacements, indirect lighting applications, ultraviolet inspection during manufacturing processes, set and costume design, and growing plants.ĭesign Correlated color temperatures of white light Traditionally, strip lights had been used solely in accent lighting, backlighting, task lighting, and decorative lighting applications. Of course, if you wire a thousand of these strips, there could be some trouble when human skin is in near proximity.An LED strip, tape, or ribbon light is a flexible circuit board populated by surface-mount light-emitting diodes (SMD LEDs) and other components that usually comes with an adhesive backing.
In short, the referenced purple light has 1/10,000 effect as compared to "true UV-B-C lights" that are used to kill bacteria in industrial water purification systems, so the strip is more like a toy. The "germicidal high-pressure Mercury lamps" have strong emission lines at 180 nm and 250 nm, and that's why they are petty harmful to skin and bacteria.
The interpretation of this chart is that any UV light longer than 320 nm is pretty harmless to living organisms and plants, while lights shorter than 300 nm have 1000X more effect and, with some intensity, would cause harm. On the other hand, there is an established model for sensitivity of live tissues to UV emissions, called " CIE action spectrum", which looks as this: The visible "purple color" corresponds to wavelength of about 400 nm. The strip of LEDs claims to emit "purple color".
