In today's rapidly advancing technological era, the application of Light Emitting Diodes (LEDs) has permeated every aspect of our lives, from common household lighting to high-end commercial displays. With their outstanding performance and energy-saving characteristics, LEDs have become a revolutionary product in the lighting industry. Today, I would like to introduce to you the H-F5D series of LEDs from QILSTE. This series is popular in the market for its excellent performance, diverse color options, and reliable quality.
The H-F5D series of LEDs from QILSTE adopts advanced InGaN and AlGaInP semiconductor materials, which not only provide excellent electro-optical conversion efficiency but also ensure the long-term stability and durability of the products. In addition, the exquisite design and precise dimensions of these products, with tolerances controlled within ±0.2mm, ensure perfect adaptation in various application scenarios.
The H-F5D series offers a rich variety of colors, from fresh green to warm yellow, to bright blue, meeting the lighting needs of different scenarios. In terms of photoelectric parameters, these LEDs exhibit characteristics of high brightness and low power consumption. For example, the H-F5DTCG green LED can achieve a luminous intensity of 5000 to 9000 mcd at a forward current of 20mA, with a power consumption of only 100mW, showing an extremely high energy efficiency ratio.
For a more intuitive presentation of these product features, the following is a table that includes the model number, color, and main parameters:
