Introduction: Select the three major attention points of waterproof lights: chassis material, optics, heat dissipation. Selecting a good waterproof lamp mainly starts from the following aspects:
GreenTouch infrared touch screen uses the high quality of transparent glass so it has excellent clarity, resolution, light transmittance and reliability. Even though there are some scratches on the surface of glass,it can still work normally. The surface of the screen has no surface coating on the plastic film or moving parts, so there is no parts will wear consumption during the usage.infrared touchscreen ensures stable performance without any ghost spots or drift.The operation is sensitive, through finger, glove, passive stylus and other opaque objects can perform accurate touch input. a high-precision IR Touch Screen.

First, the chassis material
At present, the common chassis material in the market is stretched aluminum. The overall sealability of this chassis has the common disadvantage that the sealability is bad, especially the head. Secondly, the aluminum plate absorbs more heat than the PA66. Under the same internal heat dissipation and external temperature conditions, the temperature of the aluminum plate body is higher than that of the PA66. So you can choose waterproof material beam light PA66 material, waterproof material beam with this material can be long-term high temperature, anti-aging, flame retardant, insulation, more secure than stretching aluminum.
Second, optics
Some brands of waterproof light beams on the market only use the optical structure of the original 350W beam light, and simply improve the shell, so as to achieve the effect of waterproof. Therefore, it is necessary to avoid buying this type of waterproof beam light when purchasing.
Third, heat dissipation
At present, better waterproof beam lights on the market will have four 6*6 12V DC fans at the bottom of the lamp to direct the temperature at the bottom to the outside of the fuselage, so that the temperature of the base is within a normal range.
