Solar semi integrated light

 Introduction

  Street lamp is a necessary part of every part of the street, with a primary function is to provide comfort to the driver and pedestrian. Street lamp also has a security function that is to prevent accidents and criminality. On the other hand, from environmental and economical perspectives, solar street lamp is better than the traditional street lamp, since the traditional technology uses far more energy during its operational life. Solar street lamp is a lamp that utilizes solar cell to obtain electrical energy during the daylight hour by solar radiation and then stored in the battery. At night, the energy saved in the battery is used to provide light on the street. Generally, there are two types of solar street lamps: (a) unintegrated lamp; (b) fully-integrated lamp, as shown in Figure 1. Unintegrated lamp is a lamp which are each component, i.e. lamp, solar cell, controller, and battery, separate from each other, as shown in Figure 1(a). However, the lack of this type of solar street lamp is in need of a complicated installation. Different from unintegrated lamp, fully-integrated lamp has integrated all the components of each lamp, as shown in Figure 1(b). The fully-integrated lamp causes easier installation, although the component price of this type is expensive . Semi-integrated lamp (Figure 1c) tries to overcome both problems, that is expensive and complicated installation. Semi-integrated solar street lamp only integrated solar cell, controller, and battery, while lamp is separated using cable. This configuration makes semi-integrated lamp cheaper and easier for installation that is suitable for rural area.

Comfortable cost ,easy to install. Save electricity bill.
