Why don't new solar street light bright

With the wider use of new energy, solar energy street light, how to buy high quality solar street light problem becomes crucial, quite a few illegal businessmen just interests regardless of the quality problem of the product, this will greatly damage the industry in the eyes of the masses



as the new solar energy street light [ Solar street light is a crystalline silicon solar battery power supply, valve control type sealed and maintenance-free battery ( Gel battery) Store electricity, super bright LED as light source, lamps and lanterns and controlled by the intelligent charging and discharging controller, is used to instead of the traditional public power lighting lamps. 】 Application popularization, how to buy high quality solar street light problem becomes crucial, quite a few illegal businessmen just interests regardless of the quality problem of the product, this will greatly damage the image of the industry in the eyes of the masses, now small make up to teach you about how to choose high quality solar street light:

first to understand the solar street light lamp holder is LED lamp holder, its thin and thick shell is an important factor affecting the quality of solar street lights, and there is the structure of the aluminum plate, aluminum sheet and constant current source' Constant current source, ac constant current source, dc constant current source, current generator, big current generator, also called a current source and stable current source, is a kind of wide spectrum, high precision ac current, has quick response speed, high precision of constant current, the long-term stability can work, suitable for all kinds of the nature of the load, Impedance, sensibility, capacitive) Wait for an advantage. 】 Structure, compared the size of the aluminum plate and its thickness can basically determine the quality of lamp holder and to look at whether battery energy storage battery and battery are now used in many small companies starting power 【 The starting power 'is a puzzle game. 】 Most energy storage battery, this greatly damage the life span of the solar street light, is the solar street light pole is in hot galvanizing 【 Hot dip galvanized, 镀锌) Also called hot dipping zinc and hot galvanizing, is an effective way of metal corrosion, mainly used for metal structure industry facilities. 】 Pensu and cold galvanized 【 Cold galvanizing is through electrochemical principle of a kind of technology for workpiece surface anti-corrosion treatment. 】 Coating both distinguish is on the cut, there is still a coating on the cut of galvanizing, cold galvanized no coating on the cut. Half a set of lamp holder is 60, wall thickness of 2. 8 or so. Bottom with height, and have a taper ratio, wall thickness at around 4. Hot galvanizing light pole general life in more than 20, and cold galvanizing light pole life generally in 1 year or so, as long as you can master the above points when selecting a solar street lamp basically won't be cheated.

on the market sell streetlights sort is more, the price difference is big, quality is uneven. For consumers, however, when to buy, how to choose? Because there are a lot of criminals, will use some of the poor quality of raw materials, processing production, the production of street lamp is no guarantee quality. So when to buy solar street lamp, to distinguish good or bad situation, it is very important.

solar street light quality testing methods:

the first, they should know about parts, parts of specific types are relatively more. Mainly include panels, solar battery, solar controller' Called the solar controller solar charge controller, is used for solar power generation system, the control of multiple solar cell phalanx of battery and battery for solar power inverter load automatic control equipment. 】
