Optoelectronics Technology Co., Ltd. Nanchang Ou main products are: solar lights, solar garden lights, solar lawn lights, solar wind hybrid street light series; a variety of LED light sources, solar PV modules, batteries, controller; various lampposts, patio poles, waterproof box and supporting the use of flip-flops, light control when the control switch and other electrical products. Solar lighting products are green, safe, energy-saving features solar street lamp Why use a constant-current source, the characteristics of LED lighting material determines its influenced by the environment, such as elevated temperature changes, the LED current increases, the voltage increases the LED current will increase. Long-term than the rated current, will greatly shorten the life of the LED lamp beads. And that is when LED constant current and voltage changes in environmental factors such as temperature, to ensure that their current value unchanged. 2, solar street lighting power supply current precision: some precision constant current power supply on the market is poor, as the popularity of the recommended programs constant program error of ± 8%, constant error is too large. ± 3% generally require it. 3% of the design. To fine-tune the production of power in order to achieve ± 3% error. 3, the power supply voltage of the solar street light: LED general recommended voltage is 3.0-3.5V, has been tested, mostly in 3.2V, 3.2V is calculated according to the formula so reasonable. N-series lamp beads total voltage = 3.2 * N. 4, solar lights power supply current is how much is the most appropriate: for example, the rated current of 350 mA LED, some plants used to make the outset, designed 350 mA, in fact, the current very serious fever, the more second comparison test, designed to 320 mA is ideal. 5, series-parallel solar street with wide voltage power supply board to be more wide-do: make LED solar street light power supply input voltage range of relatively wide range AC85-265V, the LED lamp series and parallel plates is very important.

Solar lighting products are green, safe, energy-saving features solar street light controller installed in most water treatment lamp, battery box, in general, do not water, but in some cases the actual project because of improper installation or some controllers The board did not do three anti-paint treatment, because of rain along the lines flow into an external terminal controller solar street light controller causing a short circuit. Therefore, it should be noted in the construction of the terminal inside the controller cable bent "U" shaped and solid type, exposed to the outside of the cable is fixed to "U" type, so that rainwater can not Drizzle a short circuit caused by the controller, in addition Outside interface is also included to apply waterproof plastic waterproof. Among the many practical applications of solar street lights, solar lights in many places not meet the normal lighting needs, especially in light of the lack of continuous rainy days and winter period is more prominent, in addition to the use of poor quality related components, another major reason is blindly reduce component costs, not according to the needs of design configuration, reducing the use of solar panels and batteries standard, resulting in a rainy day can not provide street lighting.

Solar lighting products are green, safe, energy-saving features solar light pole pole installation steps are as follows: wear a sling at the poles will play a suitable location; slowly from the transfer of lamps, taking care to avoid scratching the crane rope solar components; from the transfer process when solar street completely off the ground or completely out of the carrier material, at least two of the installer using a large wrench clamping flange, stop lamps at the beginning of the process because the bottom of the upper end of the swinging lamps caused friction with the crane slings, damage spray layer or even more; when the lamp from being transferred to the foundation at the top, slowly decentralized solar street lighting system, while rotating poles, adjust the lamp is on the road, long holes in the flange bolt; flange Solar street light falls on the ground after the company, in order to put the flat pad 30 (or flat pad 24) solar lights, spring washers 30 (or spring washer 24) and M30 (or M24) nut, with the level of foot to adjust the vertical poles degree, if the ground is not perpendicular to the poles at the poles can pad it with flange gasket perpendicular to the ground, and finally with a wrench to tighten the nuts evenly, thread locking adhesive should be applied before tightening. For M24 bolts (8.8), tightening torque for 650.6Nm, for M30 bolts (8.8), tightening torque for 1292.5Nm. Removed from the sling. Check whether solar modules face south, otherwise adjusted. Adjust the direction of the solar cell components: the necessary equipment will be installed personnel (1 - 2) to the appropriate height, the installer uses a wrench on each pole component loosening tight bolts, then the compass is based on solar street offer, reversing lights rod assembly to the proper position, the last one by one on the pole adapter assembly retaining screws and bolts to ensure uniform force. Solar street light company, Qingyunpu solar lights, solar street lights can be installed in Europe by the EU can Optoelectronics Technology Co., Ltd. Nanchang. Nanchang Ou Optoelectronics Technology Co., Ltd. (www.okled.cn) strong, credible, in Nanchang, Jiangxi solar and renewable energy industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Europe to photoelectric and you hand into the brilliant, for a better future!
