Toshiba Expands Line-up of High Power White LEDs for LED Lighting

  

The new “TL1L4 series (4A5B type)” achieve a high luminous flux of 140lm(min.) ^[1]compared to the 130lm(min.) of conventional general products of the “TL1L4 series”. 

The 4 new products are in correlated color temperatures (CCT) of 6500K/5700K/5000K/4000K with a color rendering index of Ra70. 

The new products make it possible to achieve market requirements of lighting fixture efficacy over 110lm/W^[2], and can contribute to improving luminous efficacy and lower power consumption of LED lighting applications.

*Test conditions: I_F=350mA, T_j=85°C (Hot binning)
*Luminous Flux @T_a=25°C is reference value.
*The characteristic table above is presented for typical value.

Key Features of the New Products:
* Utilizes GaN-on-Si technology^[3] developed for LED lighting
* 3.5 x 3.5mm lens-top package
* Luminous flux/forward voltage/chromaticity/color rendering index(Ra) are sorted @I_F=350mA, T_j=85°C.
* Luminous flux: 140lm(min.) @I_F=350mA, T_j=85°C
   (165lm@I_F=350mA, T_a=25°C)
* Forward voltage: V_F=2.8V@I_F=350mA, T_j=85°C
* Color temperature variation: 6500K/5700K/5000K/4000K

Applications:
Street lights, flood lights, LED light bulbs and down lights

Notes:
[1] Test conditions: I_F=350mA, T_j=85°C
[2] Under conditions of 90% driver efficiency, 90% optical efficiency, Tj=85°C
[3] Technology to produce gallium nitride (GaN) on silicon (Si) wafers.
