. Frequently Asked Questions (FAQ)

.1 What resistor value should I use?

The series resistor value (R_s) is calculated using Ohm's Law: R_s= (V_supply- V_F) / I_F. Use the maximum V_Ffrom the datasheet (2.4V) to ensure the current does not exceed the desired I_F(e.g., 20mA) under worst-case conditions. For a 5V supply: R_s= (5V - 2.4V) / 0.020A = 130 Ohms. A standard 130Ω or 150Ω resistor would be appropriate.

.2 Can I drive it with a PWM signal?

Yes, Pulse Width Modulation (PWM) is an excellent method for dimming LEDs. It maintains the LED's color characteristics better than analog (current) dimming. Ensure the PWM frequency is high enough to avoid visible flicker (typically >100Hz) and that the peak current in each pulse does not exceed the absolute maximum rating of 60mA.

.3 Why is there such a wide range in luminous intensity?

The range (18-180mcd) represents the total spread across all production bins. Individual LEDs are sorted into specific bins (M, N, P, Q, R) with much tighter ranges. You must specify the desired bin when ordering to guarantee the brightness level for your application.

.4 How long will the LED last?

LED lifetime (often defined as the point where light output degrades to 70% of initial value, L70) is not explicitly stated in this datasheet. Lifetime is heavily dependent on operating conditions, primarily junction temperature and drive current. Operating well below the maximum ratings (e.g., at 15-20mA and with good thermal management) will significantly extend operational life, potentially to tens of thousands of hours.

. Practical Design and Usage Examples

.1 Status Indicator Panel

In a multi-status indicator panel for industrial equipment, several of these LEDs (e.g., Bin P or Q for medium-high brightness) can be arranged in a row. Each is driven by a microcontroller GPIO pin through a series resistor (e.g., 150Ω for a 3.3V or 5V system). The wide viewing angle ensures the status is visible from various operator positions. The compatibility with reflow allows the entire board, including LEDs and microcontroller, to be soldered in one pass.

.2 Backlighting for Membrane Switches

A single LED of Bin R (highest brightness) can be placed adjacent to a translucent membrane switch icon to provide backlighting. The diffuse, wide-angle light from the water-clear lens helps evenly illuminate the icon. The low profile (1.1mm height) allows it to fit into slim device designs.

. Technical Principle Introduction

Light emission in this LED is based on electroluminescence in a semiconductor p-n junction made of AlInGaP. When a forward voltage is applied, electrons from the n-type region and holes from the p-type region are injected into the active region (the junction). When electrons and holes recombine, they release energy in the form of photons (light). The specific composition of the Aluminum, Indium, Gallium, and Phosphide in the crystal lattice determines the bandgap energy, which directly defines the wavelength (color) of the emitted light—in this case, red at approximately 639nm. The "Water Clear" epoxy lens encapsulates the chip, providing mechanical protection, shaping the light output pattern, and enhancing light extraction from the semiconductor material.

. Technology Trends and Developments

The general trend in SMD indicator LEDs like this one is towards even higher efficiency (more lumens per watt), which allows for the same brightness at lower drive currents, reducing power consumption and heat generation. There is also a continuous drive for miniaturization while maintaining or improving optical performance. Furthermore, improvements in package materials and manufacturing processes enhance reliability and compatibility with increasingly demanding soldering profiles required for lead-free assembly. Color consistency and tighter binning tolerances are also areas of ongoing development to meet the needs of applications requiring precise color matching.
