Solar Road Stud Lights is a street lamp that converts solar energy into electric energy for lighting. It integrates two cutting-edge technologies of solar power generation technology and LED lighting technology, and truly achieves "zero carbon and zero emissions". The
Solar Road Stud Lights system is easy to install, There is no need to lay ground cables in advance, as long as there is sufficient sunlight, it can be installed efficiently, quickly and simply. It is the new direction of road lighting in the new era, and it is also the main development target of secondary highways and urban road lighting under the party's 13th Five-Year Plan. It is widely used in the construction of new rural areas, urban and rural combined roads, campus roads, factory roads, etc. Choosing the right and suitable
Solar Road Stud Lights includes the following elements:
1. Installation and layout of
Solar Road Stud Lights: The installation and layout of
Solar Road Stud Lights needs to be installed and arranged according to the width of the road and the proposed lighting requirements. The conventional methods are: single-sided lighting, double-sided symmetrical lighting There are three types of lights, double-sided staggered lights.
2. Light source selection of
Solar Road Stud Lights: In view of the current situation of the deteriorating global environment and the continuous warming of the climate, under the promotion of national policies, the most widely used
Solar Road Stud Lights light source is LED light source.
3. Selection of
Solar Road Stud Lights: The selection of
Solar Road Stud Lights mainly examines reflectivity, illuminance, and maintenance factor. The quality of road lighting can generally be measured by three indicators of road brightness, uniformity, and glare. The quality of road lighting is reflected in:
a. Brightness level
The average brightness of the road has different brightness requirements according to the road level. Generally, expressways and main roads require a brightness requirement of more than 2cd/m2, and secondary roads and auxiliary roads or residential roads are relatively low.
b. Average illuminance
The average illuminance refers to the average value of all the illuminances of the road surface, which is the unit of illumination intensity and is generally expressed by LM.
c. Glare
Road lighting should strive to limit the uncomfortable glare to a certain range, generally expressed by G value, under normal circumstances, G=7
d. System 4. Configuration calculation:
The formula for calculating peak sunshine hours is, peak sunshine hours=A/(3.6X365)
4. Determination of the series voltage: The DC input voltage of the
Solar Road Stud Lights light source is used as the system voltage, generally 12V or 24V. When the solar module voltage is 36V, the battery voltage is required not to be lower than 2/3 of the module voltage, so the battery, control The voltage of the device and the light source should be selected at 24V.
5. Selection of
Solar Road Stud Lights controller:
Solar Road Stud Lights controller is generally made of stainless steel, which is beautiful and durable. The design of the charge and discharge controller takes into account light control, time control, overcharge and overdischarge Protection and can realize secondary energy-saving control, half-power lighting in the specified period. The battery can choose "maintenance-free lead-acid battery", most of which will be built into the control box with the charge and discharge controller.
6. Capacity calculation of solar panels: For
Solar Road Stud Lights, the overall system configuration formula: P=light source power X light source working time/peak sunshine hours; where P is the power of the battery module, the unit is W; the light source working time unit is H, the unit of peak sunshine hours is H.
7. Calculation of battery capacity: It is preferred to determine the type of battery and the storage days of the battery according to the local rainy weather. There are many rainy weather in the south, and the storage weather is generally 5-7 rainy days.
Battery capacity calculation formula: battery capacity = load power X daily working time X storage days ÷ discharge depth ÷ system voltage
Among them: the unit of battery capacity is AH; the unit of load power is W; the unit of daily working time is H; the unit of storage days is D; the depth of discharge is generally about 0.8, and the unit of system voltage is V;
8, light pole design:
Solar Road Stud Lights commonly used light pole design is a steel cone light pole, which is beautiful, strong, durable, simple in processing technology, high in mechanical strength, and easy to be made into various shapes. The cross-sections of the light poles of common characters are round, hexagonal, octagonal, etc. The taper is 1:90, 1:100, and the wall thickness is generally 3-5mm according to the force of the light pole.
9. Inclination angle design: In order to maximize the solar radiation energy received by
Solar Road Stud Lights battery modules in a year, we need to choose an appropriate angle according to the local sunshine conditions to maximize the irradiation time.
Ten. Wind resistance: In the
Solar Road Stud Lights series, a very important issue in the structural design is the wind resistance design. The wind resistance design is mainly divided into the wind resistance of the battery module bracket and the wind resistance of the light pole. part.
