4.8mm RGB Auto Color Change (Fast) Straw Hat LED

Wide 120º Viewing Angle

A Straw Hat LED has a unique lens design which causes the LED to disperse light similar to that of an incandescent light bulb. A standard LED has a relatively narrow area where it emits light,  usually less than 45 degrees. A Straw Hat LED projects light at a much wider viewing angle usually approximately 120 degrees.

This LED is unique in that it will automatically change colors when power is applied.

The wider viewing angle distributes the emitted light over a wider area eliminating the needs for external lens designs. Although not as common as standard 5mm LEDs, their costs remain consistently as low as the standard 5mm LED.

Straw Hat LEDs are available in a wide variety of colours and are equally as bright as standard 5mm LEDs.

Powering Your LED

Each model of LED has specific optimal voltage requirements. The optimal voltage is known as the Forward Voltage (Vf). When purchasing LEDs, the vendor should supply the Forward Voltage specification, which is used to determine the current limiting resistor requirement.

We offer a full range of 1/4 and 1/2 watt resistor. If you require assistance calculating the series dropping resistor, visit our Dropping Resistor Calculator. You can supply power and LED information for a single LED and multiple LEDs in series circuits.

For this LED, the specifications are:

LED Dropping Resistor Circuit

Series Dropping Resistor

The selection of the series dropping resistor in your circuit will ensure the longevity of your LED. Without the dropping resistor, your LED will have a drastically shorter life. From the chart above, match the desired power supply voltage, and the necessary dropping resistor value is listed.

Multiple LEDs in Series

LEDs can also operate with several units in series. This enables more efficient operation and lower component requirements. See our Dropping Resistor Calculator information to aid in calculating the necessary dropping resistor for multiple LEDs in series.
