Abstract
Disclosed herein is an LED flash lens unit which prevents occurrence of yellow bands or yellow rings if LED light is concentrated through an LED flash lens improving manufacturing ability and mass production to have high performance and high efficiency.
Claims13
An LED flash lens unit to concentrate LED light emitted from an LED, comprising:
- a first lens surface including reflective portions to reflect the LED light if the angle of the LED light passing through the front end of the LED is more than a designated angle, and a transmissive portion to transmit the LED light if the angle of the LED light is not more than the designated angle;
- a second lens surface to concentrate the LED light reflected or transmitted by the first lens surface;
- a beam scatter device located at the transmissive portion of the first lens surface and provided with at least one form having a designated peak and a designated valley to scatter yellow light from among the LED light;
- and
- a lens support part connecting the first lens surface and the second lens surface to each other and maintaining a designated distance with the LED.
2 more elements
A manufacturing method of an LED flash lens unit to concentrate LED light emitted from an LED, comprising:
- installing an upper core surrounding the LED flash lens unit on the LED flash lens unit;
- installing a corrosion core, to form a designated beam scatter device scattering yellow light on the lower lens surface of the LED flash lens unit, corresponding to the lower lens surface of the LED flash lens unit;
- installing a lower core in a space formed between the LED flash lens unit and the corrosion core;
- and
- injecting a lens forming material into the LED flash lens unit and then molding the LED flash lens unit.
