Problems solved by technology

[0009] The purpose of the present invention is to overcome the defects of the existing goggles and provide a new type of goggles to solve the problem that the filter and protective sheet of the existing goggles body are made of glass, resulting in heavy weight and high price. , cannot be thinned, and is not resistant to impact, and it is easy to hurt the human body after being broken, so it is more suitable for practical use
[0010] Another object of the present invention is to provide a kind of novel goggles, in order to solve the existing goggle body to reach the effect of filtering strong light, and then increase Dye (dyeing) ratio, make making difficult and low yield rate, and improve The disadvantage of manufacturing cost, so it is more suitable for practical
[0011] Another object of the present invention is to provide a new type of goggles to solve the problem that existing goggles must have through holes in the sealing layer, which increases the manufacturing process and cost, and easily infiltrates air and moisture to affect the quality of optical components. disadvantages, making it more suitable for practical

[0078] Based on the above, it can be known that this first embodiment of the goggles of the present invention does have the following effects:

[0079] 1. The present invention utilizes the first and second filters 220, 230 to be sandwiched between the front (light-receiving surface) and the back (transmission surface) of the liquid crystal filters 210. Overall, the goggle body 200 has a total Two-layer dyed (Dye) or coating 221, 231 filters, so not only can block ultraviolet (UV), but also can block infrared (IR), and achieve the effect of filtering, and use the first, The two optical filters 220 and 230 are conveniently produced by injection molding, are easy to manufacture, have a high yield rate, and can be thinned, which can relatively reduce the cost of manufacture and use.

[0080] 2. Encapsulate the first and second optical filters 220, 230 and the liquid crystal optical filters 210 by encapsulating the first and second sealing layers 240, 250 made of plastic material,...

Abstract

The invention relates to a kind of eye glass, which comprises the first optical filter, the second optical filter, at least one liquid crystal optical filter, one controlling circuit, and the first enclosing layer. Said the first and second optical filter is plastics material, and can shelter ultraviolet and far infrared. The liquid crystal optical filter is fixed between the first optical filter and the second optical filter, and gains good permeability. The invention is characterized by simple product, low cost, impact endurability, light weight and feasibility for thin-type production.

Description

technical field [0001] The invention relates to safety goggles, in particular to goggles special for welding technology. Background technique [0002] Please refer to Fig. 1 and Fig. 2, which are the front view and cross-sectional view of the existing goggles, and the structure of the goggle body of the goggles (Auto Darkening Filter, referred to as ADF) dedicated to welding technology. Existing goggles body 100 includes two (or more than one) translucent liquid crystal filters 101, a glass material translucent and coated filter 102, a glass material and translucent Optical protection sheet 103 (Protective Glass), a plastic material and opaque first sealing layer 104, a plastic material and opaque second sealing layer 105, one installed on the first and second sealing layer 104, 105 between the control circuit 108, a solar panel 109 (Solar Cell) that is electrically connected to the control circuit 108 and exposed to the outside, and two (or more than one) are electrically ...
