WHITE LIGHT SECONDARY LIGHT TRANSFORMATION STRUCTURE HAVING CAPABILITY OF EFFECTIVELY REDUCING LIGHT BIOHAZARD INDEX VALUE

摘要

A white light secondary light transformation structure having a capability of effectively reducing a light biohazard index value. The white light secondary light transformation structure comprises a lamp holder(4), a lamp housing (5) and a light emitting lamp filament (1) which is capable of generating a white light source. An outer lampshade (2) with the inner layer coated with an inner coating (2.1) containing YAC yellow fluorescent powder is arranged outside the body of the lamp housing (5). Therefore the structure for making white light emitted by the light emitting lamp filament (1) secondarily transformed is formed.
