Can the waterproof and breathable membrane be used on the lamp to exhaust the water vapor in the she

The waterproof and breathable membrane can be used on the lamp to exhaust the water vapor in the shell, and it also has micro-heat dissipation performance.

Most of these waterproof and breathable membranes use expanded PTFE waterproof and breathable materials, PTFE waterproof and breathable membranes.

Referred to as EPTFE film (Goel waterproof membrane), PTFE lamp waterproof and breathable membrane is made of PTFE resin as raw material, through some ordinary and special processing and manufacturing EPTFE molded into a microporous film with a diameter of 100-500 nanometers, and has more than 1 billion micropores per square centimeter, micropores are 700 times larger than water vapor molecules, and 10,000 times smaller than water molecules, so that Goel waterproof membrane not only allows air and water vapor to pass through the film freely, but also repels water from the membrane. Moreover, through the internal and external air exchange, the internal heat can be taken out, effectively protecting the service life of the electronic components of the lamp, and the film will be bonded with the main material and auxiliary materials through multiple die-cutting processes to form a target product style that meets the standard size or customized size.

Waterproof and breathable membrane for lamps.

Waterproof and breathable membrane (also known as Puwei waterproof and breathable membrane) is a new type of polymer waterproof material. In terms of production process, the technical requirements of waterproof and breathable membranes are much higher than those of general waterproof materials; At the same time, from the point of view of quality, the waterproof breathable membrane also has functional characteristics that other waterproof materials do not have.

Puwei waterproof and breathable membrane has the following characteristics:

1. Waterproof, dustproof, oil-proof, protection level up to IP68.

2. Chemical resistance, high and low temperature resistance, anti-aging, etc., to improve the reliability of the product in harsh environments.

3. Prevent condensation and fogging, and improve the service life of the product.

4. Micro-heat dissipation and balance pressure difference. Improve product integrity.

Puwei waterproof and breathable membrane can be used on lamps and lanterns, and is currently highly recognized by NVC Lighting and Ocean King!

Some headlights are generally directly connected to the atmosphere (i.e., the air pressure is balanced between the inside and outside). The negative pressure caused by the light when the light is turned off will cause the water vapor from the outside to be inhaled, making the scene of water mist inside the light more serious, and causing damage to the components in the lamp, especially the circuit board. Therefore, it is possible to set up air vents and use the Goel waterproof membrane manufacturer's lamp waterproof vent membrane.

Diaphragm and high air permeability cover can solve the problem of water vapor in automobile lights. While isolating the water vapor from the outside of the headlight, it ensures that the gas inside and outside the headlight can be exchanged quickly, and the waterproof and breathable membrane of the headlight can provide good protection during the operation of the headlight and prevent the invasion of water and dust from the outside.

Automobile headlamps equipped with waterproof and breathable membranes from Goel waterproof membrane manufacturers have good luminous performance even in very harsh road conditions and run smoothly for a long time. For fog lights, tail lights, signal lights, indicator lights, turn signals and other lamps, although the power of the light-emitting element is not too large, the space is relatively small, so it also needs good air permeability, and the waterproof and breathable membrane of the lamp has high protection performance.

Waterproof and breathable membrane for lights.

The principle of lamp protection is the same, due to the temperature change, the internal pressure changes greatly, and the air in the shell is discharged from the external gaps; After the lights are turned off, as the indoor temperature and negative pressure decrease, the outdoor humid air and rainwater will enter the house, resulting in long-term repeated accumulation from quantitative to qualitative changes, causing failures and shortening the lifespan. For example, the popular LED lights, LED lights have been widely used in landscape and street lights, building facades, advertising, etc., some LED lights need to be sealed and need water. However, in the case of waterproof sealing, the problem is not conducive to heat dissipation, because the heat of the LED lamp is quite large when it is working, and the poor heat dissipation will seriously affect the normal operation of the LED lamp.

It is necessary to carry out waterproof sealing here, but it does not lead to the double requirement of high temperature lamps, and some LED lamps are designed with temperature control devices, which can work under the low power consumption conditions of LED lamps when the temperature of LED lamps exceeds the set value. In order to prevent this from happening, it is generally necessary to install a breathable waterproof membrane, and the lamps and lanterns should ensure sufficient water tightness; When the temperature in the lamp rises, the pressure becomes larger, and the hot air in the lamp is discharged through the waterproof membrane with good air permeability to eliminate the heat generated by the balance pressure and enhance heat dissipation; At the same time, as the outside temperature changes, the air is moist for a certain period of time, and water vapor is unlikely to occur inside the discharge lamp, thus protecting the interior from damage. If you have more questions, you can consult us, Jiujia Communication Technology is very happy to serve you.

That's how <> protection works. This kind of membrane is called PTFE waterproof and breathable membrane. This PTFE waterproof and breathable membrane has the functions of waterproof fog, balancing pressure difference, preventing pressure accumulation, dustproof, and oilproof.

Outdoor lighting fixtures are made of waterproof and breathable membranes of outdoor lighting fixtures that continuously exchange air to maintain pressure balance inside and outside the enclosure. Install a waterproof and breathable membrane for outdoor lighting fixtures on the shell of the outdoor lamp.

After that, the pressure difference due to changes in the external temperature will no longer have a negative impact on the enclosure, as the vent membrane of the outdoor lighting fixture quickly equalizes the pressure both indoors and outdoors. Enclosure when ambient temperature and pressure change.
