2 double helix engineer Present day necessity is to save energy and to generate energy from all possible renewable sources. Solar Power, Wind Power, Hydro electric Power, new researches are being Double Helix Engineer is also into the business of Marketing, Supply & Installations of energy saving luminaries, LED lights, LED Street Lights. We have wide range of LED Lights, from 3W to 250W of different types of LED Lights & Lamps. Our LED Light manufacturer M/s Deepaksshi Display Devices Pvt. Ltd. is a certified LED Lights manufacturer, has various models of LED lights and LED Street Lights of all wattage with marvelous technique and all latest equipments, testing facility as per industrial standards.

3 Introduction This is an attempt to utilize a percentage of free solar energy available plenty for day today life. Solar Powered Street Lights are today s most suitable & cost effective Street Lighting system and energy saver while it uses LED Street Lights. Solar Powered street Light are raised light sources powered by Photovoltaic panels generally mounted on the lighting pole with battery.

4 Photovoltaic panels charge a rechargeable battery, which powers a fluorescent or LED Lamp during the night. Solar Powered Street Lighting system consists of PV Module, LED Lamp, Charge Controller, Battery & Pole. This system is a energy efficient system which is environment friendly, and can be utilized at far flung areas where no power line is connected. Typically 80W - 120W per LED Street Light is sufficient to illuminate the road. (whereas depends on the ht. of pole, lux level reqd.)

6 Features of Solar Street Lights Solar panels turn on and off automatically by sensing outdoor light using a light sensor. Timer also can be installed. Solar streetlights are designed to work throughout the night. Many can stay lit for more than one night if the sun is not available for a couple of days. Solar Street lights installed in windy regions are generally equipped with flat panels to better cope with the winds.

7 Advantages of Solar Powered LED Street Lights NO electricity bills. Solar street lights are independent of the utility grid. This is a non polluting source of electricity. Solar street lights require much less maintenance compared to conventional street lights. Since external wires are eliminated, risk of accidents is minimized. Separate parts of solar system can be easily carried to the remote areas and Installed solely.

9 Solar Panel Mono/Poly-crystalline Solar Photo- Voltaic cells arranged in array of the panel to generate required voltage. Present days solar panel has become efficient & cheaper than earlier. Panels are made highly durable, weather proof, environmental friendly, suitable IP and satisfying all industrial quality standards. Solar Panel mounted on top of the street light pole to harvest max. Sunlight.

12 Battery Bank High efficiency Battery of suitable capacity shall be connected in the system. The circuitry shall connect the charge controller, Automatic ON/OFF switches etc. Battery may be mounted on the pole top or at ground level with weather proof housing.

13 LED Street Lights LED Lamps can be utilized for street lights as LED needs less power and emit more light. LEDs Street Lights offer better reliability / durability. LEDs are easier to control and dimming. LEDs offer reduced Lumen depreciation (less light output reduction over time) LEDs are normally DC driven. Driven by constant current

14 Technical Parameters of LED Street Light Say for 70W LED Street Light Input Voltage : V AC/ 24V DC Power : 70 w Equal to sodium lamp watts :180 w Luminous Flux : >7600 lm LED : High Power LEDs Emitting Color : white, warm white Color Temperature : K Color Rendering Property : >60 Protecting Class : IP 65 Net Weight : 6.5 kg approx. Lifespan : 50,000 hrs

15 LED Street Light Model Our Trishul Series of LED Street Lights are most suitable Light to spread max. light, illuminating pole to pole gap. These LED lights can be used as luminaire in Solar Powered Street Lighting.

18 Street Light Replacement All Street Lights with HPSV and Halogen Lights may be replaced by Solar Powered LED Lights with all accessories with little modification on existing Poles. Solar Powered street light can be installed at streets, Highways & far flung areas too. Energy efficient LED street Lights can be used to illuminate all type of roads(4m,8m, 10m wide etc.) by considering standard Pole height.
