What are the Best Water-proof LED Lights

What is Water-proof?

Protection Grade of LED lamps

Guide: with the strengthening of people’s safety awareness, the purchase of LED lamps and lanterns is not limited to lighting and heat dissipation. Dust proof and waterproof have become another demand of us.

Recently, there have been torrential rains in the south, and many places have been affected. Our lamps and lanterns are also subject to the waterproof test. Let’s understand the meaning of the protection level.
IP XX is an international code used to identify the protection level. IP grade is composed of two numbers, the first number is dust-proof, the second is waterproof, and the larger the number, the better the protection level is.

Dustproof grade (the first X ), and the waterproof grade (the second X )

0: no protection	0: no protection
1: Prevent large solid intrusion	1: There is no effect when water drops into the shell
2: Prevent the invasion of medium sized solids	2: There is no effect of water or rain water dripping on the shell from an angle of 15 degrees
3: Prevent small solid intrusion	3: Water or rain drops from 60 degrees to the shell without any effect
4: Prevent solids larger than 1 mm from entering	4: No effect from any angle
5: Prevent harmful dust accumulation	5: Low pressure injection at any angle has no effect
6: Completely prevent dust from entering	6: High pressure jet water has no effect
/	7. It can be soaked in water for a short time (15cm-1m, within half an hour)
/	8: Immerse in water for a long time under certain pressure

IP 65 is dust dense (no dust entering) and water spray proof (spraying water in all directions of the shell has no harmful effect), which can completely prevent dust from entering.

When it is subjected to violent sea wave impact or strong water spray, the water inflow of electrical appliances should not reach harmful influence. The protection grade of LED street lamp, wall lamp, projection lamp, buried lamp, step lamp, wall lamp, tennis court lamp, soft strip lamp, flashlight and building lighting lamp all reach IP65. IP66 is dust dense (no dust into) and high-pressure jet water, which can completely prevent dust from entering.

When it is subjected to high-pressure violent water jet, the electrical appliances are not obstructed. The protection grade of LED searchlight series reaches IP66.
IP68 waterproof test is: ensure to work in 10m water depth for 2 weeks without water inflow; put it into 100m water depth and test for 12 hours, it can still maintain the good performance of the product. The protection grade of LED underwater lamp reaches IP68, which is in line with the highest international protection level.

A qualified LED lamp should not only have a good image and full functions, but also have a high safety protection coefficient, which is what the public want.

Are LED Lights Waterproof?

There are many types of LED lights, according to their design and use occasions, some are waterproof, and some are not waterproof.

Generally speaking, indoor lighting fixtures, such as tubes, downlights, spotlights, etc., have a protection level of IP20 or below, that is, they are not waterproof. Therefore, the user manual needs to specifically indicate that this lamp should not be used in underwater or humid environments.

However, most outdoor lighting fixtures are waterproof, because outdoor lighting fixtures suffer from the erosion of wind, frost, rain and snow all the year round. If the waterproof performance is not good, it will have a considerable adverse effect on the performance of the fixture, and it will also bring Security risks.

In theoretical design, IP44 can play a better dustproof and waterproof function, but considering that within the design life cycle of LED lamps (usually 5 years), outdoor lamps will encounter various rain and haze all year round. , Frost and hail weather, so for safety reasons, the best protection level can be IP65 and above, so as to ensure that no dust and water droplets penetrate into the lamp body, thereby protecting the life of the lamp and the safety of users/crowd.

What are the Best LED Lights for Boats?

LED lamps have obvious advantages as marine lighting

Tachyon LED lighting: Ships have been in an environment of high salinity, high humidity, and high vibration for a long time. Facing such bad weather, the lamps and lanterns for marine lighting must also undergo rigorous tests. LED lamps are energy-saving and environmentally friendly, with long lifespan, and high efficiency. They have obvious advantages as marine lighting.

1. High light efficiency and low power consumption, saving energy

The power of a single LED lamp is generally 0.05-1W, and different needs can be met through the cluster mode, with very little waste. The LED is driven by DC, the light source has high luminous efficiency and low power consumption. Compared with the luminous intensity, the energy consumption is only 10% of incandescent lamps and 50% of fluorescent lamps. Using LED lighting can save a lot of lighting energy.

2. Strong earthquake resistance and long service life

The LED is small in size, light in weight, and the outer shell is epoxy resin encapsulated. It is not afraid of seawater corrosion and has strong shock resistance. It can not only protect the internal chip, but also has the ability to transmit light and condense light.
Just design a fixed structure suitable for marine use. The design of additional explosion-proof lampshade is simpler and lighter in structure, and the service life of the light source is generally between 50,000 and 100,000 hours.

3. Green and environmental protection, high safety

LED lamps directly convert alternating current into direct current. The working voltage is low, mostly 1.4-3V; the working current is only 10mA, and the ultra-high brightness is only 1A.

LEDs do not contain harmful gases, lead, mercury and other heavy metals; do not need to be inflated, do not need a glass shell, have good impact resistance, good shock resistance, and are not easily broken; there is no infrared and ultraviolet radiation in the spectrum, and better LED lighting can be Achieve no stroboscopic phenomenon; waste can be recycled, low heat, no pollution to the environment; no mosquitoes around the lamp body at night, making the lighting environment cleaner and tidy, known as “green energy”.

4. High luminous efficiency, high efficiency of lamps

The luminous efficiency of incandescent lamps and halogen tungsten lamps is 12-24lm/W (lumens/watt), the luminous efficiencyof fluorescent lamps is 50-80lm/w, and the luminous efficiency of sodium lamps is 90-140lm/W. Most of the power consumption becomes Heat loss. The light efficiency of LED can reach 50-200lm/W after improvement, and the light has good monochromaticity, narrow spectrum, and can directly emit colored visible light without filtering.

Traditional fluorescent lamps emit light in 360°, and the opposite direction is useless. Usually the efficiency of traditional fluorescent lamps is only 70%, while the light-emitting angle of LED lamps is usually 120°, which can be adjusted according to requirements. The light efficiency is higher than traditional lamps. .

5, no noise, no radiation

Qualified LED lamps have no noise, and are more suitable for working places such as the cockpit and chart room that require high concentration and crew rest places. Traditional lamps use alternating current, so 100~120Hz strobe will be produced. Better quality LED lamps convert AC power directly into DC power, so that there is no stroboscopic phenomenon and very low radiation.

What Happens When LED Lights Get Wet?

When choosing LED floodlights, pay attention to whether you are using an integrated floodlight or a high-power floodlight. If it is an integrated floodlight, it uses a sealed and waterproof method to protect the lamp.

Once water enters, the interior light source will slowly corrode and decay until the entire lamp is damaged. If it is a large amount of water, it may cause the entire lamp to burn out.

The high-power LED floodlights are fully glued and waterproof, and have a defensive function against a small amount of rain or water droplets. The test is the performance of the waterproof glue. For large amounts of water ingress, high-power LED floodlights are also electronic products. Although the structure can be well waterproof, from the point of view of the connection of the power supply, the leakage of electricity in these places will also cause damage to the entire lamp.

In addition, as an electrical product, LED lights need to be energized to work. Therefore, if the lamp body enters water due to poor waterproof performance, it will cause leakage accidents and cause danger to the people around, because generally municipal water is conductive.
