ຄວາມແຕກຕ່າງລະຫວ່າງ VCSEL ແມ່ນຫຍັງ, EEL, ແລະ LED ສໍາລັບແຫຼ່ງການຂະຫຍາຍຕົວຜົມແສງສະຫວ່າງສີແດງ?

Red light hair growth devices (such as hair growth caps, ໝວກກັນກະທົບ, and combs) use Low-Level Laser Therapy (LLLT) with 650–670 nm red light to stimulate hair follicles and promote hair growth, offering an innovative solution in alopecia treatment. The choice of light source directly determines device efficacy, ຄ່າໃຊ້ຈ່າຍ, market positioning, ແລະປະສົບການຂອງຜູ້ໃຊ້, making it a core consideration for manufacturers designing hair growth products. Current mainstream light sources include Vertical-Cavity Surface-Emitting Lasers (VCSELs), Edge-Emitting Lasers (EELs), and Light-Emitting Diodes (ໄຟ LED). They differ significantly in beam characteristics, ຄວາມແມ່ນຍໍາຂອງຄວາມຍາວຄື້ນ, ປະສິດທິພາບ, lifetime, and applicable scenarios.

Differences of Red Light Hair Growth Light Sources

VCSEL/EEL/LED

1. VCSEL (Vertical-Cavity Surface-Emitting Laser)

ລັກສະນະ: Circular beam, small divergence angle (10–20°), wavelength 650–670 nm, efficiency 30%–40%, lifetime 20,000–50,000 hours, power 5–10 mW, easy to integrate.

2. EEL (Edge-Emitting Laser)

ລັກສະນະ: Elliptical beam, large divergence angle (10–50°), wavelength 630–670 nm, efficiency 20%–30%, lifetime 10,000–20,000 hours, power 5–10 mW, large size.

3. LED (Light-Emitting Diode)

ລັກສະນະ: Incoherent light, large divergence angle (120°), wavelength 620–700 nm, efficiency 10%–20%, lifetime over 50,000 ຊົ່ວໂມງ, power 10–20 mW, easy to integrate.
