Precision equipment, add the cost and complexity of encapsulation process.It is blue meanwhile current high color temperature LED street lamp has light pollution
Be present potential hazard to periphery biology in light composition, for example have a negative impact to the user biological rhythm and pace of moving things, show as suppressing epiphysin
Secretion, causes circadian rhythm disturbances, causes dyssomnias etc..
Silicon substrate GaN-based thin-film LED one side light extraction, has the good unique advantage of light direction, and luminous intensity distribution designs more
What is added is simple.However, the lighting engineering route of blue chip combination fluorescent material, because scattering of the fluorescent powder grain to light is made
With so that light source becomes body light source, destroys the characteristic of chip one side light extraction, also greatly adds the optical design of light fixture
Difficulty.Meanwhile for street lighting occasion, the gold-tinted of low colour temperature has a higher penetrability, but blue chip combination gold-tinted
Fluorescent material is difficult to the coordinated development of colour temperature and light efficiency.
