| Q01 | ｜ | How to use LITEON LED Lamp in circuit design? |
(1) Circuit model A: One lamp connects one resistor. Brightness can be uniform.
(2) Circuit molde B: Two or more lamps connect one resistor. Brightness will be a little different due to I-V characteristics.

| Q02 | ｜ | Can LITEON LED LAMP be passed with IR-reflow process? |
IR-reflow is for SMD type LED. Normal lamp LED is thro-hole type, so it can’t be passed with IR-reflow process.
| Q03 | ｜ | How many colors can Thru-Hole LED LAMPS of LITEON support? |
Color | Wavelength | Chip |
White | X: 0.31~0.41 Y: 0.32~0.39 | InGaN |
Blue | 460~475nm | InGaN |
Cyan | 500~510nm | InGaN |
Green | 520~535nm | InGaN |
Yellow Green | 565~575nm | AlGaInP / GaP / GaAsP |
Yellow | 584~594nm | AlGaInP / GaP / GaAsP |
Amber | 600~610nm | AlGaInP / GaP / GaAsP |
Orange | 610~620nm | AlGaInP / GaP / GaAsP |
Red | 620~660nm | AlGaInP / GaP / GaAsP / AlGaAs |
| Q04 | ｜ | Product Meet Rohs, Halogen Free, and Pb Free? |
The whole LITEON LED Product already pass Rohs, Pb-free and Rohs, and then we provide Halogen Free product to customers, too.
| Q05 | ｜ | What is the Luminous Flux?What is the Luminous Flux? |
Unit : lumen, Luminous Flux is a measure of the power of visible light. Photopic flux, express in lumens, is weighted to match the responsivity of human eyes.
| Q06 | ｜ | SMD LED Category? |
(1) PCB Substrate, call Chip LED.
(2) Lead - Frame Substrate, call PLCC.
(2) Lead - Frame Substrate, call PLCC.
| Q07 | ｜ | What is soldering condition of LED Lamp? |
Soldering iron and wave soldering is only one time.
Soldering iron | Wave soldering | ||
Temperature Soldering time | 300°C Max. 3 sec. Max. (one time only) | Pre-heat Pre-heat time Solder wave Soldering time | 100°C Max. 60 sec. Max. 260°C Max. 5 sec. Max. |
| Q08 | ｜ | How to select LED Lamp in LITEON Data sheet? |
In LITEON Data sheet, we will show IV, Hue, Vf, and view angle. Users can select the suitable spec. from LITEON’s LED lamp.
| Q09 | ｜ | How to check view angle in LED lamp? |
Circuit model A: One lamp connects one resistor. Brightness can be uniform.
(1) 3mm & 5mm lamps are normal lens, so view angle will be uniform in any direction.
(2) Oval lamp is ellipse lens, so view angle is different in X-Y axis.
