LAMP FOR DRAWING - A simplified explanation of the abstract
This abstract first appeared for US patent application 18575666 titled 'LAMP FOR DRAWING
Simplified Explanation: A light shielding plate is placed between a light emitting element and a projection lens, with an opening in the plate allowing for a specific light distribution pattern to be formed.
- The light shielding plate blocks part of the light emitted from the light emitting element.
- An opening in the plate shapes the light distribution pattern.
- The inner surface of the opening prevents light from entering the projection lens, reducing color unevenness.
- Increasing the plate thickness does not lead to color irregularities due to light reflection.
Key Features and Innovation:
- Light shielding plate for controlling light distribution.
- Opening in the plate shapes the light distribution pattern.
- Inner surface of the opening prevents light from entering the projection lens.
- Reduces color unevenness in the light distribution pattern.
- Allows for increased plate thickness without affecting color quality.

Original Abstract Submitted
A light shielding plate for shielding part of light from a light emitting element to a projection lens is arranged between the light emitting element and the projection lens, and an opening penetrating the light shielding plate is formed in a required region of the light shielding plate. With this configuration, the drawing light distribution pattern can be formed as a light distribution pattern corresponding to the opening shape of the opening. In this configuration, the inner peripheral surface of the opening has such a surface shape that light emitted from the light emitting center of the light emitting element does not enter the projection lens. Thus, even if the plate thickness of the light shielding plate is increased, occurrence of color unevenness in an outline portion of the drawing light distribution pattern due to light reflection on the inner peripheral surface of the opening is effectively reduced.
