TLGE248

The TLGE248 is a kind of LED lamp. It is designed for panel circuit indicator. There are some features as follows: (1)InGaAlP GREEN LED; (2)wide radiation; (3)elliptical lens: colored transparent lens; (4)low drive current, high intensity green light emission; (5)plastic molded colored transparent lens provide high ON-OFF contrast ratio; (6)fast response time, capable of pulse operation; (7)applications: suitable for outdoor message signboard, full color panel, backlight.

The following is about the maximum ratings (Ta=25) of the TLGE248: (1)forward current (DC), IF: 50 mA; (2)reverse voltage, VR: 4 V; (3)power dissipation, PD: 140 mW; (4)operating temperature range, Topr: -30 to 85 ; (5)storage temperature range, Tstg: -40 to 120.

The last one is about the electric and optical characteristics (Ta=25) of the TLGE248: (1)forward voltage, VF: 2.27 V typ and 2.8 V max at IF=20 mA; (2)reverse current, IR: 50A max at VR=4 V; (3)luminous intensity, IV: 153 mcd min and 360 mcd typ at IF=20 mA; (4)peak emission wavelength, P: 574 nm typ at IF=20 mA; (5)spectral line half width, : 11 nm typ at IF=20 mA; (6)dominant wavelength, d: 571 nm typ at IF=20 mA.
