Document Type and Number:
Japanese Patent JP6481695
Kind Code:
B2
Abstract:
The purpose of the present invention is to provide a lamp capable of reproducing a desired light color at a low cost and a method for manufacturing such a lamp. This lamp (106) is provided with a light source unit (2), a cover (1), and a wavelength discrimination layer (6). The light source unit (2) has LEDs (200). The LEDs (200) are covered by a cover (1). The wavelength discrimination layer (6) is provided to the cover (1). The wavelength discrimination layer (6) is provided with a first wavelength discrimination layer (6A) and a second wavelength discrimination layer (6B). The first wavelength discrimination layer (6A) has first wavelength discrimination characteristics. The second wavelength discrimination layer (6B) has second wavelength discrimination characteristics, which have different spectral radiation intensity characteristics to those of the first wavelength discrimination characteristics.
