What is the specification of LED light?

LED colour

Wavelength Range (nm) Colour VF @ 20mA
500 – 570 Green 1.9 – 4.0
570 – 590 Yellow 2.1 – 2.2
590 – 610 Orange / amber 2.0 – 2.1
610 – 760 Red 1.6 – 2.0

What is module in LED?

An LED module is a nifty gadget designed to be self-contained to function independently or to be added to a complimentary unit. It is made of parts constructed to produce light from a light emitting diode (LED). LEDs modules are favored for their environment-friendly fixtures.

What are LED modules made of?

LED modules, also called LED arrays, are simple LED assemblies. They use one or more diodes arranged on a circuit board. The circuit boards that LEDs use involve printed circuit boards (PCB) made of materials designed to improve heat dissipation.

What is the voltage of 10mm LED?

How To Identify LED Terminal Leads

10mm LED Specifications
LED Model Optical Qualities
RGBC422-14 Multi-Color Auto Color Change Slow Voltage: 3.0v-3.2v Typical: 3.1v Current: 20mA
WC422-13 Super Bright White Voltage: 3.0v-3.2v Typical: 3.2v Current: 20mA
RC422-05 Super Bright Red Voltage: 1.9v-2.1v Typical: 2.0v Current: 20mA

What is the operating voltage of LED?

Typically, the forward voltage of an LED is between 1.8 and 3.3 volts. It varies by the color of the LED. A red LED typically drops around 1.7 to 2.0 volts, but since both voltage drop and light frequency increase with band gap, a blue LED may drop around 3 to 3.3 volts.

How do LED modules work?

Light Emitting Diodes, or LEDs for short, involve applying a voltage to a semiconductor material so that electrons are knocked loose from the surface of the material, in turn emitting particles of light energy known as ‘photons’.

Can LED be use a dimmer?

Use an LED Dimmer switch A standard dimmer switch cannot be used with an LED light as you will never be able to dim the LED light either completely or not very well. LED lights need their own special electronic dimmer switch to have a fully functioning and dimming light.

How do you connect LED modules?

On the secondary size you connect the positive terminal of the first LED module (leftmost module in Figure 1) into the positive terminal of the LED driver. Then you connect the negative terminal of the last module (rightmost module in Figure 1) to the negative terminal of the LED driver.

What is the voltage of 8mm LED?

8mm LED

input voltage 2.0-3.6v
Viewing angle 5-60 degree
Forward current 60ma

What is the difference between 3mm and 5mm LED?

5mm are the most common size you’ll see, and they can be extremely bright! 3mm LEDs are not as bright but are smaller, and are good for indication (like an LED that tells you something is on). They’re not as good for illumination because they have a smaller area that is lit.

What is the maximum voltage for an LED?

LED V/I characteristics

Characteristics Unit Maximum
Forward voltage (@350mA, 85°C) V 3.48

What are the specifications for a LED system?

Specifications for LED systems should state that surge-protection devices (SPDs) be provided for each luminaire. SPDs should be UL1449-recognized for all phases (line/neutral, line/ground, and neutral/ground).

Where can I find IES lm-79 for LED lighting?

Engineers should specify that IES LM-79 testing for an LED light source be performed by one of the DOE’s LED Lighting Facts-approved lab s. A specification that incorporates IES LM-79 can be found from the United Facilities Guide Specifications (UFGS): Submit test report on manufacturer’s standard production model luminaire.

Are there different sizes of LEDs for different applications?

Our LEDs are available in a full rainbow of colors, sizes along with special application LEDs such as Ultraviolet (UV) and Infrared (IR). Our LED Specifications cover each model of LED we carry, including 3mm, 5mm, 8mm, 10mm along with high-power LEDs. Super bright 3mm LEDs are extremely bright.

Why are LEDs included in photometric lighting specifications?

LED light sources’ lumen output should be included in the specifications because lighting designs and photometric layouts are based upon lumen output. Most other light sources besides LEDs “burn out” and have their “end of life” listed as the time where 50% of the lamps have failed.
