⚙️ HMINLED Engineering Portal: Photometrics, Global Lux & LPD Codes

ENGINEERING GRADE

📐 1. The Photometric Chain: How Lumens, Beam Angle, Lux & IES Relate

💡 Lumens (lm)

Total Light Output

The raw total amount of light emitted by the fixture in all directions (Total Engine Power Output).

📐 Beam Angle (°)

Light Spread Angle

Determines how light is directed. Narrow beams (30°) spotlight specific areas; Wide beams (120°) flood spaces evenly.

🎯 Lux (lx)

Target Surface Brightness

Actual brightness hitting floor or desk (1 Lux = 1 Lumen/m²). Calculated by Lumens, Height & Beam Angle.

📁 IES File

3D Photometric Profile

Standardized digital file encoding precise 360° light intensity. Imported into DIALux software to render 3D Lux maps.

🛡️ 2. Truth About Lumen Decay: Why HMINLED Stays Bright for Decades

❌ The Cheap LED Trap: Overdriven Current

Current Overclocking: Cheap drivers overdrive low-grade chips to fake temporary high brightness.
Severe Heat Traps (T_j > 105°C): Destroys internal phosphor layers rapidly.
Rapid Light Decay: Loses 40%–50% brightness in 18 months, turning into a sickly yellow glow.

✅ HMINLED Solution: Zero-Overdrive Engineering

Rated Gold-Wire Chips: Runs tier-1 chips at optimal rated current for maximum Lumens per Watt.
Heavy-Duty Heat Dissipation (T_j < 65°C): Thick aluminum substrate cools chips in milliseconds.
<5% Decay in 50,000 Hours: Certified LM-80 performance. Maintains 95%+ brightness for decades.

📊 3. Global Illuminance (Lux) Standards by Region & Application

Recommended official target Lux levels for visual productivity across international codes:

Application Scenario	USA Code (IESNA)	Europe Code (EN 12464-1)	China Code (GB 50034)	Japan Code (JIS Z 9110)
Garage, Workshop & Utility	150 – 300 Lux	150 – 300 Lux	150 – 300 Lux	200 – 300 Lux
Office, Basement & Storage	300 – 500 Lux	500 Lux	300 – 500 Lux	500 – 750 Lux
Kitchen, Dining & Living Room	150 – 300 Lux (Task: 500)	300 – 500 Lux	150 – 300 Lux	200 – 500 Lux
Bedroom, Closet & Accent	100 – 200 Lux	100 – 200 Lux	75 – 150 Lux	100 – 200 Lux
Industrial High-Bay & Warehouse	150 – 300 Lux	200 – 300 Lux	150 – 300 Lux	150 – 300 Lux

🏢 4. Lighting Power Density (LPD) Mandatory Energy Code Caps

Pass Building Energy Audits & Occupancy Inspections With Zero Risk

LPD (Lighting Power Density = Total Installed Watts / Floor Area) is legally mandated by building energy codes. HMINLED’s High-Efficacy LEDs (130+ lm/W) deliver full target Lux while keeping total wattage well under statutory caps:

Application Area	US Max LPD (ASHRAE 90.1 / Title 24)	EU Max LPD (EN 15193 / EPBD)	China Max LPD (GB 50034)
Garage, Workshop & Utility	< 0.40 W/ft²	< 4.5 W/m²	< 4.0 W/m²
Office, Basement & Storage	< 0.60 W/ft²	< 6.5 W/m²	< 7.0 W/m²
Kitchen, Dining & Living Room	< 0.55 W/ft²	< 6.0 W/m²	< 6.0 W/m²
Bedroom, Closet & Accent	< 0.35 W/ft²	< 4.0 W/m²	< 4.5 W/m²
Industrial High-Bay & Warehouse	< 0.45 W/ft²	< 5.0 W/m²	< 5.0 W/m²
