LENS STRUCTURE FOR VEHICLE LAMP - A simplified explanation of the abstract
This abstract first appeared for US patent application 18519087 titled 'LENS STRUCTURE FOR VEHICLE LAMP
The present invention aims to efficiently distribute a light beam that would otherwise be directed to a lower area towards a direct front area and its vicinity.
- The lens structure for a vehicle lamp includes a light emitting surface at one end in an irradiation direction Y+, designed to emit a light beam in the direction Y+.
- The light emitting surface features an optical cut with a convex shape protruding in the direction Y+, an apex portion at an intermediate vertical position, and an asymmetrical placement in the vertical direction.
- The optical cut includes a flat portion from the apex to a predetermined position closer to an upside Z+ than the apex, with a smaller curvature than adjacent portions in the vertical direction.
- This design helps concentrate the light beam towards the front area, improving visibility and efficiency.
Potential Applications: - Automotive lighting systems - Street lighting fixtures - Industrial lighting solutions
Problems Solved: - Efficient distribution of light beams - Improved visibility in front areas - Reduction of light wastage towards lower areas
Benefits: - Enhanced visibility for drivers - Energy-efficient lighting solutions - Better illumination in targeted areas
Commercial Applications: Title: "Innovative Lens Structure for Enhanced Light Distribution in Vehicle Lamps" This technology can be utilized in automotive lighting systems, street lamps, and industrial lighting fixtures to improve visibility and energy efficiency.
Questions about the technology: 1. How does the asymmetrical placement of the optical cut contribute to the efficiency of light distribution? 2. What are the potential cost-saving benefits of using this lens structure in vehicle lamps?
Original Abstract Submitted
An object of the present invention is to make it possible to efficiently distribute a light beam that would otherwise be distributed to a lower area to a direct front area and the vicinity thereof. A lens structure for a vehicle lamp includes a light emitting surface at an end in an irradiation direction Y+ and configured to irradiate a light beam in the irradiation direction Y+ from the light emitting surface . The light emitting surface includes an optical cut that has a convex shape protruding in the irradiation direction Y+, that has an apex portion at an intermediate portion in the vertical direction, and that is provided asymmetrically in the vertical direction. The optical cut has a flat portion residing from the apex portion to a predetermined position located closer to an upside Z+ than the apex portion , and the flat portion has a smaller curvature than portions adjacent in the vertical direction Z to the flat portion
