Description

TECHNICAL FIELD

[0001] The utility model relates to laminated glass technical field, concretely relates to a laminated glass of light transmittance adjustable. BACKGROUND

[0002] As a part of building, the window has always been paid attention by the architect. The coated glass, especially the Low-E energy-saving glass, has entered thousands of families and become the most popular product in the field of building glass. However, the traditional Low-E coated glass has only one state and cannot change according to the change of outdoor environment. For example, in the southern region of China, the building window adopts the sunshade type Low-E product in the hot summer, and its transmittance is about 10% to 40%. In the morning and evening when the light is weak, the indoor light is obviously darker than the outdoor light due to the shielding of the sunshade type window, which greatly affects the indoor lighting and increases the expenditure of lighting cost. More importantly, in the cold winter, the sunshade type window makes the sunlight unable to enter the indoor, and the indoor temperature is lower than the outdoor temperature, so people feel colder in the house.
