Meter mode reduces the quantity and intensity into the light of human eye so that human eye is not easy to distinguish insulating part 53.
By optical principle it is found that when light is incident on transparent or semitransparent material, the inside of transparent or semitransparent material
Surface due to cloud caused by light diffusion meeting or muddiness appearance, with the luminous flux of the luminous flux of diffusion and permeable material it
The percentage of ratio indicates, i.e. mist degree.As seen from the above description, insulating part 53 is made of transparent insulation material, thus light shines
It will produce haze issues when being mapped to insulating part 53, the muddy appearance of insulating part 53 be easy to cause the visuality of insulating part 53.Thus
In some other embodiment, it is unrestrained that light caused by insulating part 53 can also be reduced by reducing the mist degree (Haze) of insulating part 53
It penetrates.Specifically, the dispersibility by adjusting high refracting particles in the material so that mist degree is less than 0.15.When the mist of insulating part 53
Degree makes the appearance that insulating part 53 is not in muddy when light irradiates when being less than 0.15, have the preferable transparency, to
Reach good visual effect.
