Solar street lamps use intelligent street lamp light source comparison solution

Solar street lamps use what light source is better? Configuration of the battery solar street lamps generally have a lead-acid battery, nickel battery, nickel metal hydride batteries. Solar street lamps require battery should have suitable capacity. Battery will not only meet the night lighting



solar street lamps use what light source is better? Solar street light configuration of battery generally have lead-acid battery' Definition: the electrode is mainly composed of lead and its oxide, the electrolyte is a battery of the sulfuric acid solution. 】 , nickel battery, nickel metal hydride battery' Nickel metal hydride battery, 镍- M H ydride电池等等) The positive active material is mainly made of nickel, the cathode active material is mainly composed of hydrogen storage alloy made from a kind of alkaline battery. 】 。 Solar street lamps require battery should have suitable capacity. Battery can not only meet the night lighting under the premise of the daytime the solar cell components ( Solar energy battery components is of high efficiency crystalline silicon solar cell lines of toughened glass, super white cloth, EVA, transparent TPT backboard and the composition of aluminum alloy frame. 】 The energy stored as far as possible, at the same time also can store for meeting the needs of continuous rainy night lighting electricity. If the capacity of the battery Battery in the prescribed conditions ( Including the intensity of discharge termination voltage, discharge current and discharge) Sent out how much electricity or discharge duration called battery capacity, unit or a. a. h min. 】 Is too small, is not able to meet the needs of night lighting: on the contrary, too much battery capacity is not appropriate, always in kui state of electric battery, not only affect battery life, at the same time also can cause waste. The battery, solar controller and solar cells Solar cell is also known as 'solar cells' or 'cell', is a kind of electricity generation by using sunlight directly photoelectric semiconductor wafer. 】 Match, street lamp. Generally speaking, the solar battery power must be more than four times higher than the street lamp power, system can work normally. Solar battery voltage to 20% ~ 30% more than the working voltage of the battery, to ensure normal power transmission to the battery. Battery, solar street lamp controller capacity should be more than 6 times the street lamp, consumption of advisable. What light source, will directly affect the work condition of the solar street light. Using low voltage energy-saving lamps, solar lamps and lanterns commonly low pressure sodium lamp' Low pressure sodium lamp is the use of low pressure sodium vapor discharge light electric light source, in its glass shell coated with the infrared reflection film, droop is smaller and the highest luminous efficiency of electric light source. 】 , energy-saving lamps, LED light source. Following a brief introduction of the characteristics of various light sources. (1) low voltage energy-saving lamps: small power, high light efficiency, service life of 2000 hours, low voltage lamp black, generally suitable for solar energy lawn lamp' Solar energy lawn lamp is a kind of green energy lamps and lanterns, safety, energy saving, environmental protection, easy installation, etc. 】 , courtyard lamp. (2) low pressure sodium lamp, low pressure sodium lamp high photosynthetic efficiency, Up to 200 lumens,) , equipped with inverter is required. Because of the low pressure sodium lamp cost is higher, the current ratio is not high. (3) electrodeless lamp: small power, high light efficiency. The lamp in 220 v common city' In accordance with the provisions of the Japanese 'local autonomy', the population is more than 50000 people and urban households and businesses population accounts for more than 60% of the area may have a 'city'. 】 Under the condition of electricity use, life can reach 50000 hours, the service life is down on solar lamps and lanterns.
