What is the main reason for the brightness of solar street lights?
Today's rural areas can be described as ever-changing. The development of the beautiful rural construction project has enabled the villages to pass the road. It is not enough to have a road, and a street lamp is a truly beautiful country. Solar street lights are easy to install, require no wiring, and are green and clean, so they are widely used in beautiful rural construction projects. At present, solar street lamp manufacturers are mixed in the market. Many solar energy street lamps purchased by villagers often have the phenomenon that “lights are not bright”. This is mainly due to the low brightness of solar street lamps caused by bad business, which causes this phenomenon to occur. Today, Xiaobian tells you about the main factors related to the brightness of solar street lights, so that everyone can choose to choose high-intensity solar street lights.
First, the internal chip of solar lamps
The inner lamp of the solar lamp is mainly composed of LED chips. The lumen count of the LED chip is an important factor in reflecting the light efficiency (brightness). At present, many Taiwanese wafer chips are used by many merchants on the market. The lumen number is 110LM/W, and the lumens of LED chips of big brands are high. For example, the number of Philips lumens is 120~130LM/W, and the Puri chip can be as high as 150LM/W, so you want high brightness of solar street lights, try to choose LED chips of big brands. Our company currently uses the Puri chip, which has high luminous efficiency. Under the same configuration conditions, the brightness of the solar street lamp can be increased by one-fifth.
Second, solar street light configuration size
The so-called solar street light configuration refers to the size of solar panel power and battery capacity. The higher the power of the solar panel, the higher the battery capacity, and the higher the overall brightness. Some people are eager to buy solar street lights at a low price, and choose low-profile solar street lights, so the brightness is certainly not guaranteed. Therefore, if you want to choose a solar street light with good brightness, try not to choose a low configuration.
The above is the main factor affecting the brightness of solar street lights. In addition, Xiaobian here to tell you that there are many low-cost 3.2V solar street lights on the market. These solar street lights are very low in configuration and the system is unstable. The brightness is definitely not ideal and the service life is long. There are no 12V solar street lamps that have a long life. If the buyer's budget is sufficient and the pursuit of brightness and quality, then choose a normal 12V system voltage solar street light.
As a new energy technology product, solar street light is gradually used in rural areas. It absorbs sunlight to generate electricity through the volt effect, clean and pollution-free, and is deeply loved by people. However, there are many types of solar street lamps on the market. There are three types of solar street lamp system voltages: 3.2V, 12V, and 24V. Many buyers face these three system voltages but don't know how to choose them. Today, solar street lamp manufacturers make a comparative analysis of the common 3.2V and 12V system voltages, so that everyone can choose which one is better.
First, 3.2V solar street light system voltage
Advantages: 3.2V solar street lights are cheap, and household small solar lights use this system voltage more economically.
Disadvantages: low brightness, low efficiency, high requirements for line body and LED lamp bead, because solar street lamp power is at least 20W, so it will cause excessive current, light source damage is fast, system is unstable, often leads to replacement after two years of use. Lithium battery and light source.
Second, 12V solar street light system voltage
Advantages: high brightness, working efficiency is about 20% higher than the 3.2V system voltage, the system is stable, and the overall service life is longer.
Disadvantages: Of course, the price will be higher than the 3.2V solar street light.
