What is the difference between LED projector lenses and LED headlight bulbs?

The lens is, in fact, a convex glass lens that serves the purpose of focusing light. Parallel rays passing through the lens converge at a single point, where a light source can then be positioned at the focus. The convex lens has the ability to transform these rays into parallel light, thereby enhancing the efficacy of LED lights, allowing for greater irradiation distance. The detailed differences between lens-equipped LED lights and standard LED lights are as follows.

1. The difference in light source: The LED light source with a lens is evenly distributed, whereas the ordinary LED light emits scattered lines.

2. The heat dissipation of the chip varies: LED lights with lenses dissipate heat more slowly, while ordinary LED lights without lenses dissipate heat more rapidly.

3. The irradiation distance differs: The irradiation distance of the LED projector lens is relatively short, while that of the ordinary LED lamp is longer and broader.

4. The lighting effect varies: The LED lamp with a lens provides a more concentrated illumination, with a scattering amplitude that is more scientifically designed, whereas the lighting effect of the ordinary LED lamp is inferior compared to that of the LED lamp with a lens.
