How Much Do You Know About Waterproof Performance of Outdoor Solar Lights?

Solar-powered lights that installed outdoors usually need to withstand the test of various bad weathers such as heavy rain, snow, frost, which is possible from time to time. If the waterproofing measures of solar lights are not in place, the water will penetrate the interior of the lights and corrode the internal circuit, resulting in a lighting failure, and the service life of solar lights will also be shortened. Therefore, taking the waterproof performance into full consideration is quite necessary before choosing solar powered lights outdoor. Today, we will share some knowledge about the waterproof performance of solar powered landscape lights outdoor.

At present, the waterproof technology of outdoor led lights is mainly divided into two directions: structural waterproof and material waterproof. Structural waterproof means that it forms a waterproof structure after all parts of the item fitting together. And material waterproof is to reserve the position of sealing glue to seal electrical components during product design, and use glue material to make the electrical components completely airtight and thus realize waterproof function during assembly.

With the development of waterproof material technology, the special potting glue for various types of LED lights from various brands continue to appear, for example, modified epoxy resin, modified polyurethane resin, modified organic silicone, etc. Different chemical formulas have different physical and chemical performance indexes on elasticity, molecular structure stability, adhesion, UV resistance, heat resistance, low-temperature resistance, water repellency, and insulation performance of the potting compound. The waterproof performance of the solar landscape spotlight is finally judged by its IP rating.

The IP (Ingress Protection) rating of LED lights is the protection level of the light against solid (dirt, dust, etc.) objects and liquid (water). There are two numbers on the IP protection level. The first number (0 to 6) is fixed in the IP protection level. It shows resistance to solid objects. The second number (0 to 8) means a waterproof level. The larger number, the more waterproof.

The most common wireless solar powered landscaping lights on the market are IP65 waterproof LED lights. They provide maximum protection for solid particles and have a certain resistance to liquid particles due to the silicone sealing washer. However, if you want to fight more extreme weather outdoor, you need an outdoor light with a higher waterproof level, that is IP67 waterproof outdoor light. They add a gluing sealing treatment based on IP65 to make the light completely sealed. Even if immersed 1M deep underwater, the lights are still able to work normally.

LITOM outdoor solar landscape spotlight is exactly the representative of IP67 waterproof technology, having super-priority in waterproof function during outdoor use.

Extreme weather is the main reason that your solar lighting needs to be IP67 waterproof. The surface temperature of the outdoor solar lights in summer can rise to 60℃, ultraviolet rays have a destructive effect on the protective coating of the shell, plastic parts, potting glue, sealing rubber ring adhesive strip, adhesive, etc. After a long time, there will be aging cracks, which will damage the waterproof performance of the solar lights; The temperature in winter can be reduced to minus zero, the plastic parts become brittle, and they are easy to crack under the pressure of ice and snow, which seriously affects the airtightness of the lights.

Solar lights exposed to the outdoor environment need to withstand the various extreme weather above, which is why you need to choose the outdoor solar lights with a higher waterproof level reaching to IP67, just to keep the outdoor lights running in good performance even in high heat, storm, and snow days. The more waterproof, the longer service life.

Summer camping is always pleasant, giving people a wonderful chance to close to nature. But do you know what is the essential equipment that you must take out for summer outdoor camping? It is solar lighting. As lights can help boost the ambiance as well as providing illumination. Life is no more wonderful than all family members sitting in front of the tent at night, talking and laughing, with lighting surrounded, very romantic.

However, summer is always rainy, your solar lights for outdoor camping need to be waterproof enough. Nobody wants the wonderful atmosphere to be interrupted by a sudden power-off due to water flowing into the interior of the light and causing a shortcut. So, choose a solar spotlight with higher IP rating. Enjoy your summer outdoor camping!

Best Quality 60W Solar Street Light in Pakistan
Rated 5.00 out of 5 based on 3 customer ratings Rated 5.00 out of 5 based on 3 customer ratings With growing concerns on electricity shortages and keeping in view high fares, Ultronics has introduced Solar Street Lights with 60 Watts power. This solar street light is a complete solution for people choosing to move on alternate energy solutions. This solar light is built with high quality ABS Material that stands tall under tough conditions. An ideal selection for housing societies, parks, factories, mines and open warehouses this light is IP65 certified which means it is completely water proof. Back up Time: 6-8 hours (on full mode) when charged under bright sunlight1. how can i made a circuit for solar street light?You could be using leds or a compact fluoro for this. These will be for use with a 12V battery. It may be you want to reconsider using 40W, as less power is much more feasible. About 10W of CFL or LED supply will be the same as a 40W incandescant lamp, and last much longer. If using leds you will need an efficient switch mode current regulated source to drive them. You can expect similar efficiency to a compact fluorescent lamp. The leds will need heatsinks. The size of the battery and the panel are critical parts of the design. The power supply would be a 12V battery. The light runs at night only. WIth some care the solar panel itself can be used as a sensor to switch on the lights by measuring the battery voltage. When under charge it will be around 13.85V, using a float charger. The current is inherently limited by the panel. A simple but effective charger is to connect the solar panel by a switch (P channel mosfet as a high side switch or relay) when the voltage is below 13 volts and disconnect it when the voltage approaches 14V (lead acid battery). Use a reverse blocking diode with the panel. Note that gel type batteries are not very suitable for operation in sunlight in the tropics at least. When the battery is below 12.6V consider it as night time. Otherwise use a separate sensor for sunlight. Thus you have three voltage comparators for these 3 voltages. These can be a schmidt trigger with the correct hysteresis. You need a reference supply. A small 5V regulator is simple. This uses a solar panel designed for charging a 12V battery, meaning it has 36 cells. The OC voltage at standard conditions is 22V. Look up data sheets specs for panels. If the lamp runs 12h per day, and the power is 10W, then it uses 120Wh per day. With a 12V system this is 10Ah. The battery needs to be at least 10Ah, especially considering overcast days, and the need to not discharge it below 50% of capacity. This looks like a 40Ah battery therefore. The maximum charge rate should not exceed 4A (10h rate). The solar panels must provide 10Ah per day too, but... The battery takes 140% of its discharge to recharge, so now 14Ah per day. Allow extra to catch up after a period of overcast weather, at least 20Ah per day. The rated current occurs with full sun. There is an equivalent of full sun hours for your region, likely 2-5h a day. In the tropics 5h per day. Thus we need 20Ah in 5 hours, so a current of 4A. This agrees nicely with a 40Ah battery. So for a 10W lamp operating 12h a day in the tropics we need something like a 40Ah battery, and a 4 amp x 36 cell panel. This will be rated around 15V * 4A = 60W. A bigger panel is ok within reason, but should have a bigger battery so it does not charge too quickly. A bigger battery may be needed to increase the lifetime, and allow a reasonable number of days without sun if overcast weather lasts more than a day or too. The electronics should all be designed for outdoor use, vermin proof, including rats to ants, weather-proof and able to operate at 60C ambient temperature. The link below has an example of a P channel mosfet high side switch driven by a voltage comparator. Use a 10A or more rated switch and the comparator needs a reference so it turns on at 14V and off at 13V.2. All in One Solar Street Light Manufacturer with Best Price in IndiaAll In One Solar Street Lights All In One solar street light is a new-age form of lighting solution integrating solar panels, charge controller, LED light and battery. These lights are available in two varieties, with infrared motion sensors and without, as part of the unit. All In One solar street lights are becoming popular due to their compact design and multiple other advantages. Motion sensors help to adjust the LED brightness intelligently in All In One street lights. Infrared (IR) and passive infrared (PIR) motion sensors are used for motion sensed detection of emitted/reflected infrared energy. The All In One solar street lights with motion sensor switch on in the evening and after a time delay of 30 seconds, the lights automatically reduce their brightness to 20%. Motion sensor is capable of detecting infrared waves that radiate from moving objects, thereby electronically increasing the brightness of the lights. Once motion is detected, there is 100% brightness and if there is no motion detected in the area after the time delay, the light gets automatically adjusted to a dim mode of 20%. The biggest advantage of solar street lights with motion sensors is that they add a sense of security and safety to your property while providing better battery life. Features of All In One Solar Street Lights Controllers used in All In One solar street lights PWM or MPPT charge controllers are used in All In One solar street lights. PWM controller acts as a switch between the battery and solar panel. The battery is charged with constant 3-stage charging, i.e., bulk, float and absorb. Pulse width modulation or PWM is the technique to modulate the pulse width to change the voltage and frequency of energy from solar panel to charge the battery. One of the greatest pros of PWM controllers is that it helps to prevent overcharging while charging the battery. As for the cost, PWM controllers are less expensive compared to MPPT controllers. MPPT (maximum power point) controller offers an indirect connection between the battery and the solar panel. The DC/DC converter takes extra photovoltaic voltage and transforms this into additional current at lower voltage. MPPT controllers adjust the voltage to maintain the most efficient level of power. In cooler conditions, MPPT controllers are observed to be more effective than PWM controllers due to their ability to capture extra PV voltage. Solar panels used in All In One solar street lights Though both monocrystalline and polycrystalline solar panels are used in solar street lights, polycrystalline solar panels are most commonly used in All In One solar street lights due to their cost effectiveness. Since most of the All In One solar street lights use motion sensors, they do not require solar panels with more wattage. Batteries used in All In One solar street lights Lithium ion phosphate (LiFePO4) batteries are widely used in All In One solar street lights due to their multiple advantages. LiFePO4 batteries offer upper and lower voltage protection and longer lifespan. These batteries can operate in different temperature range and are maintenance free. LiFePo4 batteries are the perfect choice for All In One solar street lights due to their relatively small and light feature. Lithium-ion as well as lead acid batteries are also used in some All In One solar street lights. Light source used in All In One solar street light LED light source is used in as it consumes less energy and gives higher luminosity. Installation of All In One solar street lights Compared to integrated solar street lights, the installation of All In One solar street lights can be carried out easily. The All In One solar street light can be effortlessly mounted due to its compact size and also due to the fact that there are no wires or cables to connect. They can be installed either on a pole or on a wall. The pole should be fixed to a flat ground without inclination. The light fixture should be installed to the pole before erecting the pole. The pole should go at least 3 feet deep inside the ground. The basic cage must be secured to the ground using concrete. It is essential to place the poles at even widths to provide uniform brightness to the entire area. The poles must be placed in the right position and angle so that the panels get sufficient direct sunlight throughout the day. Since All In One solar street lights have dusk to dawn feature, they need very minimal maintenance once installed. Rain water washes away most of the dust and dirt off the solar panels; however, routine cleaning of the panels helps the efficiency of All In One solar street lights. The solar panels can be cleaned by wiping them with a soft cloth or spraying water with a jet spray. Occasionally, you may inspect the installation bracket and the mounting arm to look for any damage. The All In One solar street lights are automatic in its function. They are operated with infrared motion sensor which helps to detect movement in its field and illuminate the lights, thereby ensuring security. Also, the controller can be set to operate in a timer-based manner where in the lights operate in full brightness for the first four hours and then later, in lower light for rest of the time. With the motion sensor and dimming options, the All In One solar street lights tend to save energy, thereby guaranteeing longer life to the lighting fixture. No cable work or electric equipment is needed, so the installation/construction cost is lesser. No need of manual intervention after installation, so the management cost is lesser. The lights are powered solely by using solar energy and no conventional energy is used, so the operation cost is lesser. Installation is easier and faster and maintenance is very minimal. Compared to integrated solar street lights, All In One street lights are less expensive. Since All In One solar street light requires direct sunlight to give its full potential at night, it may not be able to meet requirement of the areas with insufficient sunlight. Since having shadows may obstruct the sunlight to fall onto the solar panels to charge them efficiently, installation sites may be limited. Initial investment to purchase All In One solar street light is high compared to traditional lighting system. However, the benefit of advantages is far beyond the shortcomings of disadvantages. With the technological advancement, All In One solar street lights will be more and more used in the coming future.3.
