LED module with lens and without lens difference
LED module with lens and without lens difference
The main difference between ED module with lens and without lens is light control, light efficiency, application scenarios and so on. The following is a detailed analysis:
1. Light control
- LED module with lens:
The lens can precisely control the distribution of light, such as concentrating or astigmatism.
With a lens design, light can be concentrated in a specific area (such as a concentrating lens) or spread evenly (such as an astigmatic lens).
Suitable for scenes that require a specific spot shape or Angle.
- LED modules without lens:
The light distribution is more natural, usually divergent, and there is no obvious focusing effect.
The light Angle is large, suitable for scenes requiring large area uniform lighting.
2. Light efficiency
- LED module with lens:
The lens absorbs some of the light, resulting in a slight reduction in light efficiency (usually a loss of 5%-15%).
However, through the light gathering action of the lens, the light intensity of certain areas will be significantly increased.
- LED modules without lens:
The light is directly emitted, the light efficiency is high, and there is no light loss caused by the lens.
However, the light distribution is scattered, and the light intensity in certain areas may be insufficient.
3. Application scenario
- LED module with lens:
Suitable for scenarios that require precise light control, such as:
Stage lights, spotlights, car lights.
Scenes requiring remote lighting (e.g. street lamps, searchlights).
Scenes requiring specific spot shapes (e.g. projection lights, decorative lights).
- LED modules without lens:
Suitable for scenes requiring large areas of uniform lighting, such as:
Indoor lighting (e.g. panel lights, ceiling lights).
Advertising light box, backlight.
General lighting that does not require precise light control.
4. Cost
- LED module with lens:
The cost is higher due to the addition of lenses.
Lens material (e.g., PMMA, PC) and design (e.g., aspherical lenses) also affect cost.
LED modules without lens:
Simple structure, low cost.
5 Dissipate heat
- LED module with lens:
Lenses may affect heat dissipation, especially in designs with high sealing.
Better heat dissipation design is needed to ensure LED life.
LED modules without lens:
The heat dissipation performance is better, the light is directly emitted, and the heat is more easily distributed.
6. Appearance and design
- LED module with lens:
More professional appearance, suitable for high-end lighting products.
Lenses can be designed in different shapes (e.g. round, square) to meet aesthetic needs.
- LED modules without lens:
Simple appearance, suitable for general lighting products.
Summary and comparison table:
