Description of the drawings
Fig. 1 is the structural schematic diagram of one embodiment of the anti-automobile lamp that hazes of the present invention.
Specific implementation mode
The invention discloses the anti-automobile lamp lens (can be referred to as lens) that hazes of one kind, are equipped at least two layers
Eyeglass, the gap between adjacent two layers eyeglass are in closed vacuum state.Each layer eyeglass is the car light that can play light transmission
Appearance parts or a part thereon.
It is specifically warm on lamp distribution mirror since the most of phenomenon that hazes is caused by lamps and lanterns internal-external temperature difference
Degree is low compared with the dew point of humid air in lamp chamber, thus there is a phenomenon where humid air to condense in lens inner surface.The institute of the present invention
Anti- dead air space of the automobile lamp lens by the setting vacuum between adjacent two layers lens eyeglass that haze is stated, to be formed
Theoretic heat insulation layer so that the outside of internal layer eyeglass is hardly influenced by car light ambient temperature, and then to greatest extent
Ground reduces the temperature difference between outside in internal layer eyeglass, to avoid the lens generated due to the temperature difference from hazing phenomenon.
The technical solution adopted in the present invention does not use immersion coating, is not in trickling, current mark, failure, discoloration etc.
Problem fundamentally solves the problems, such as that car light hazes.
Two layers or more of this heat insulation layer, the setting number of plies of the heat insulation layer can be formed by the way that the eyeglass of more layers is arranged
It can be determined according to actual conditions such as use environment, the requirements of automobile.
In adjacent two layers eyeglass, outer layer eyeglass can shade internal layer eyeglass completely or partially outer surface.When outer layer eyeglass
When the shade internal layer eyeglass of part, institute's mask regions preferably comprise internal layer eyeglass low-temperature space (i.e. far from light radiation region, lead to
It is frequently located in the corner location of car light, the temperature in this region is usually lower than other regions when car light works), especially innermost phase
Mask regions selection can be reduced innermost layer eyeglass low temperature by adjacent two layers of eyeglass in low-temperature space when using part shade with emphasis
Internal-external temperature difference near area alleviates this region because air is difficult to the phenomenon that easily causing vapor accumulation due to circulation.
When outer layer optic portion shade internal layer eyeglass, outer layer eyeglass can be an Integrated lens, if can also be divided into
Dry is divided eyeglass, i.e., the gap between inside and outside two layers of eyeglass that can be continuous, and can also be discontinuous.It is close on car light
The region at car light edge is not all low-temperature space, that is to say, that low-temperature space is possible and discontinuous, therefore accordingly can use gap not
Continuous design.
Automobile lamp lens in Fig. 1 is only two layers of eyeglass and the complete shade internal layer eyeglass outer surface of outer layer eyeglass

1 inside of outer layer eyeglass is free from the heat insulation layer gap 2 of steam, not will produce the phenomenon that hazes.When the low temperature inner layer of outer layer eyeglass 1
Eyeglass 3 transmit when, need the convection current and radiation by heat insulation layer gap, due to both thermaltransmission modes heat transference efficiency compared with
The solid conduction efficiency of monolithic lens eyeglass wants much lower, therefore cryogenic energy can not evenly and effectively be transferred to internal layer mirror
Piece, thus the temperature difference on internal layer eyeglass both sides minimizes, and then avoids internal layer eyeglass since the temperature difference generates the phenomenon that hazes.
The eyeglass of the lens is molded for injection molding.The anti-automobile lamp lens that hazes can be that integral type is noted
Being moulded into type, i.e., integrated injection molding connects between the described eyeglass, alternatively, the eyeglass can be respectively seperated, and between each other by outer
Portion edge is welded to connect.
