Our LED light source module solutions for ceiling light/panel light meet customers' indoor lighting needs for ultra-thin designs, high light uniformity, and low glare. The design focuses on optical diffusion effects and home décor compatibility.
I. Core Processes of Our LED Light Source Modules
Ceiling light panel modules are based on FR-4 or AL substrates. The mainstream processes are side-emitting and direct-emitting, as detailed below:
Substrate Selection and Fabrication
Side-emitting modules: FR-4 fiberglass board (0.8-1.2mm thickness) is preferred due to its low cost and ease of processing into slim strips, suitable for side mounting. Low-power side-emitting modules do not require strong heat dissipation, and the insulation and flatness of FR-4 meet the requirements.
Direct-lit modules: Utilize ultra-thin aluminum substrates (0.5-0.8mm thick, thermal conductivity ≥1.0W/(m・K)), resulting in higher LED density. The aluminum substrate allows for rapid heat dissipation, preventing heat buildup in the central area. High-end products may use copper-based copper-clad laminates to improve heat dissipation efficiency for high-power panel lights (>40W).
Substrate surface treatment: Employs either tin plating or OSP (organic solder mask) processes. Tin plating provides better oxidation resistance to solder joints, while OSP is more suitable for high-density mounting and produces a smooth board surface without affecting the LED beam angle.
II. Core Parameter Requirements for Color Rendering Index (CRI), Luminous Efficacy, and Color Temperature: The parameters of the ceiling light panel should meet the requirements for indoor lighting comfort and visual health. Specific parameters are as follows: Color Rendering Index (CRI, Ra)
General Home Decor (Living Room, Bedroom): Ra≥80, accurately reproducing the colors of furniture and walls, avoiding color cast;
High-End Home Decor, Study, Children's Room: Ra≥90 (high CRI module), R9 (red light CRI)≥50, reproducing warm colors such as red and pink more naturally;
Commercial Scenarios (Clothing Store, Showroom): Requires Ra≥95, combined with high color accuracy (color tolerance ≤3SDCM), ensuring the effective display of product colors.
Luminous Efficacy (lm/W)
Side-emitting module: Laboratory luminous efficacy **≥120lm/W**, actual system luminous efficacy (including light guide plate loss) ≥90lm/W;
Direct-emitting module: No light guide plate loss, laboratory luminous efficacy **≥130lm/W**, system luminous efficacy ≥100lm/W;
Energy-saving product: Uses flip-chip LEDs, luminous efficacy can be increased to 150-160lm/W, suitable for home energy-saving needs.
Color Temperature (CCT)
Bedroom & Children's Room: 2700K-3000K Warm White Light, soft light, creating a cozy atmosphere;
Living Room & Dining Room: 3500K-4000K Neutral White Light, balancing brightness and comfort, suitable for daily activities;
Study & Kitchen: 5000K-6500K Cool White Light, clear light, improving visual clarity for work and operation;
Multi-functional Needs: Mainstream products use a three-color temperature adjustable module (2700K/4000K/6500K), switchable via switch or remote control.
Other Key Parameters
Glare Ratio (UGR): Residential ceiling lights must have a UGR ≤ 19, commercial panel lights must have a UGR ≤ 16;
Flicker: Constant current drive, no flicker or deep low flicker, fluctuation depth ≤ 30%, protecting eyesight;
Lifespan: L70 lifespan ≥ 30,000 hours, meeting a 5-8 year usage cycle for home use.
III. LED Chip Selection Ceiling light panel lights primarily use low-power SMD surface-mount LED chips. The differences in selection between side-emitting and direct-emitting modules are as follows: Side-emitting module LED chips
Mainstream models: 2835 SMD LED chips (single chip power 0.2-0.5W), small size (2.8×3.5mm), suitable for slender strip module arrangements; some ultra-thin side-emitting modules use 3014 LED chips (3.0×1.4mm), even thinner, suitable for ultra-thin lamp bodies within 10mm.
Performance requirements: 120° beam angle, luminous efficacy 140-160lm/W, good color temperature consistency (color tolerance ≤5SDCM), avoiding color differences in side light.
Direct-lit LED Module Chips
Mainstream Models: 2835, 5730 SMD LEDs;
2835 LED: 0.5W per chip, suitable for medium-power direct-lit modules (10-30W), high density, uniform light distribution;
5730 LED: 1W per chip, luminous efficacy 130-150lm/W, suitable for high-power direct-lit modules (30-60W), high brightness per chip, reducing the number of chips required;
Emerging Option: COB Integrated LEDs (5-30W), uniform light output, no graininess, suitable for large panel lights (diameter > 500mm), can achieve "shadowless lighting" when paired with a diffuser.
Special Requirements for LED Chips:
Color Rendering: High color rendering modules require full-spectrum LED chips with a spectral coverage of 380-780nm, close to natural light, making them more suitable for children's rooms and studies;
Temperature Resistance: Operating junction temperature ≤120℃ to avoid accelerated light decay after prolonged use.
