What's LED Tape?
LED Strip Light is also known as LED tape or ribbon light. They're designed for both indoor and outdoor use depending on whether they’re water resistant. IP20, IP44, IP65, IP67, and IP68 are available meeting various of installation requirement.
Besides, the strip is flexible and can be divided at any point between LEDs. It is extremely versatile in accent lighting, backlighting, task lighting, and decorative lighting applications. They are also used as computer lighting, costume lights, toys, and display ambient lighting, and alcove lighting. Nowadays, LED flexible strip light can be seen here and there and will be everywhere.
An Ingress Protection(IP) rating of a product is represented by two numbers. The first number determines the protection rating against solid objects or materials. The second number determines the protection rating against the ingress of liquid/moisture.
IP 20: Uncoated LED tape is not considered to have any resistance to water ingress, it was rated as IP20 for some physical ingress resistance.
IP65: Glue Coated
IP67: Silicone Tube encased
IP68: Silicone tube with Silicon Glue
Single Color, non-addressable: Every LED on the strand is a single white color typically ranging from 2700K to 6500K in colour temperature, or any of several monochrome colors covering the range of the visible spectrum (generally from 400-700 nanometers in wavelength).
Here are highly recommend you LEDwise brand strip light if you have special requirement for the color temperature. Our strip light ranges from 2200K to 25000k in color temperature.
Multicolor, non addressable: Each LED is capable of displaying red, green, blue, or all three (white), driven by three input power rails. All the LEDs display the same color at any one time, but the color can be manipulated by varying the voltage applied to each of the three power inputs.
RGB, addressable: Multiple colours and addresses. Each LED has its own chip meaning they can be individually triggered for chasing, strobing, and colour changing.
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. The most common types of SMD:
3528, single color, non-addressable, very low power;
5050, containing three LEDs allowing for RGB and addressable strips as well as higher power levels;
2835, a newer single-color SMD having the same surface dimensions as the 3528 but a larger emitter area and a thinner design with an integrated heatsink allowing for higher power levels;
5630/5730, a newer replacement for single-colour 5050 SMDs which can operate at slightly higher power levels and have high efficacy.
Less common designs may have 2016,2216, 3014, 4014, 7020, 8020, or other SMDs.
LED strip lights most commonly operate on 12 or 24 volts of direct current from a power supply, sometimes referred to as a driver. Mains voltage LED strips are also available. These have the advantages of being usable in much longer single runs without a brightness drop along the length, but are less flexible and heavier due to higher voltage and current ratings and thick coatings for shock safety and high IP ratings in their intended outdoor positions, with limited cut points. No separate power supply is needed, although there must be a rectifier between the mains supply and the end of the LED strip.
The most common FPC designs use multiple parallel circuits consisting of passive dropper resistors in series with a certain number of LED SMDs, to operate at a certain current and power level with the expected input voltage. This design is referred to as constant-voltage and is rather sensitive to small variations in input voltage and to the voltage drop that occurs along long lengths of the strip when driven from a single power input. An alternative design is the “constant current” design where each parallel circuit of several SMDs includes a small integrated circuit to provide a fix current to that group of LEDs, within a wide range of applied voltages. This allows the strip to operate at the same power level and brightness along its entire length, or with some variation in the driving voltage.
The color rendering index defines the ability of a light source to identify colors and is measured on a scale of 1 – 100. On this scale, a rendering of 1 is monochromatic light, and a rendering of 100 is natural sunlight, so you can think of the scale as a measure of the quality of light produced by the source.
For example, have you ever stood under an old street light at night and wondered why the color of a car or your wheelie bin doesn’t seem the same as it does during the day? Although the lamp used in the street light gives off a lot of light, the CRI is very low so the appearance of any color is transformed.
On commercially available light sources the CRI scale may also be referred to as the Ra or CIE Ra value. This is the name of the international standard for the CRI scale.
The example below demonstrates the change in how colors are rendered at decreasing values on the Ra scale.
The higher Ra, the better artificial lighting source. The lower Ra value, the more unnatural colors appear when illuminated by the light source. Equally important to finishes and hues are how people look in the space.
To ensure a safe environment at work the European Union has set a standard stating that a minimum Ra 80 is required in the workplace.
For strip light, it also has CRI>70, CRI>80 or CRI>90. LEDwise can also provide CRI>95. When the most accurate color rendering is essential, Ra 95+ is recommended.
