Comparison of various indicators of solar street lamps and traditional street lamps

Compared with the advantages and characteristics of traditional luminaires, with the increasing scarcity of the earth's resources, the investment cost of basic energy is rising, and various safety and pollution hazards are ubiquitous. As an inexhaustible and inexhaustible safety and environmental protection, solar energy has received more and more attention. In this way, solar lighting products have emerged with the popularization of solar water heaters. Here, solar street lamps and urban circuits are used. The effect of the lamp is used to compare:

Contrast 1: Solar street lights are easy to install without laying cables: When installing solar street lights, just make a cement base and then fix it with stainless steel screws.

Contrast 2: The electricity cost of the mains lighting street lamp is expensive: the high-cost electricity is fixed in the work of the mains lighting street lamp, and the maintenance and replacement of the line and other configurations are required for a long time without interruption. The maintenance cost will increase year by year.

Solar street lamps are free of electricity: one-time investment in solar street lights, no maintenance costs, three years of recoverable investment costs, long-term benefits.

Contrast 3: There is a safety hazard in the lighting of street lighting: the lighting of street lighting is affected by construction quality, landscape engineering, material aging, power supply is not normal, and conflicts in water and electricity pipelines bring many safety hazards.

Solar street lights have no safety hazards: solar street lights are ultra-low voltage products, stable, safe and reliable.

Other advantages of solar street lights: green and environmental protection, can add new love points for the development and promotion of noble ecological communities, and continuously reduce the cost of property management. Reduce the cost of the owner's public share.

In summary, the solar street light has no hidden dangers, energy saving, no consumption, green environmental protection, simple installation, automatic control, maintenance-free and so on. It will definitely bring obvious advantages to the sales of real estate and the construction of municipal projects.

The solar street light consists of the following parts: solar panels, batteries, solar-powered controllers, illuminators and tubes. It is an automatic control working system. As long as the working mode of the system is set, it will automatically run. Solar street lights are ideal road lighting. With the improvement of people's life and the continuous development of society, it will be widely used. The sun gives the light of the earth to illuminate humans at night.

Features of solar lamps:

Energy-saving: The solar energy photoelectric conversion provides electricity, which is inexhaustible.

Environmental protection: no pollution, no radiation.

Safety: There are no accidents such as electric shock or fire.

Convenient: simple installation, digging construction, no power outages.

Long life: high technology content, control system, international brand, intelligent generation design, reliable quality.

High grade: technology products, green energy, the use of units attaches importance to technology, green image improvement, grade upgrade.

Less investment: one-time investment and AC equivalent (production and electricity investment from substation, power, control box, cable, engineering complex) one-time investment, long-term use.

Wide application: solar energy source and nature, so all places with sunshine can be used, especially suitable for green landscape lighting, high-end residential and outdoor lighting, tourist attractions coastal landscape lighting and embellishment, industrial development zones, industrial and mining enterprises street lights, each University outdoor lighting.

Energy saving data

Energy saving (80 sets of solar street lights and ordinary street lights)

Electricity fee: Calculate 250W*8=2000W=2 kWh per lamp for 8 hours per day, 80*2=160 degrees per 0.8 kWh of electricity: 160*0.8=128 yuan per day + loss of 30 yuan=158 Yuan, one year electricity bill 158 * 365 = 56880 yuan.

The total power consumption of the entire market is: 240000W

Working 12 hours a day, the electricity cost per year is: 81,030 yuan

(2) The life of AC power is up to 2 years, and it is changed every two years. It is continuously circulated and the cost is quite high. The cost per change is 43820 yuan.

Solar life is calculated according to the accessories, and can be used for free for 5 years before replacement.

Five years to save electricity costs: 81,030 yuan * 5 years +242,280 yuan (common lighting costs) -510240 = 137,190 yuan

Introduction to LED light source

specification:

Power: according to customer requirements

Luminous flux is greater than or equal to 80-100LM/W

Features:

The forward voltage is applied to both ends to directly emit red, yellow, green, cyan, orange, purple, and white light. High-power LEDs are used for high luminous efficiency.

Insert the anti-anti-peak circuit to avoid the positive and negative poles from being connected and burning the light source.

A wide range of illumination, while solving the interference between the lamp and the lamp.

Any combination of series and parallel can be used to flexibly adjust the intensity of light according to the needs of the guests.

It is a low voltage power supply, safe and reliable.

The solid light source has a simple structure and is resistant to impact, vibration and breakage.

Cold light source, good controllability, fast response, repeated and frequent, not tired.

The service life reaches 3-5 million hours, eliminating the need for frequent maintenance.

Energy efficient, ultra low power consumption.

Green and environmentally friendly, there are no harmful elements in the production of heavy metals, no radiation.

The power is divided several times, and the power is adjusted periodically to save power consumption without affecting the lighting. Suitable for street lights, garden lights, lawn lights, colorful casts.
