With the development of science and technology, the requirement of intelligent control and energy save increases rapidly. From the above two points, a new design scheme of LED light brightness control is proposed in this paper. The brightness would be kept constant in the designated region. The constant brightness is realized by the illumination of the surrounding and LED light. The total circuit includes detection circuit and control circuit. The detection circuit is used to examine the outside brightness and transfer information to the control circuit. The control circuit determines the current of LED light.

This study examines the objective foundations of strategic management as a necessary tool for studying the existing experience of the company, its indicators, as well as subsequent conclusions and justifications for the future chosen development strategy. The relevance of the research topic determines the modern challenges studied and considered in the work, and the external threats that companies face during the global economic crisis, taking into account macro and microeconomics, financial accounting and company marketing. The analysis of the existing main indicators of the activity of a commercial enterprise of the Kyrgyz Republic (on the example of “Energy Save” LLC) allows drawing conclusions and substantiating the most effective and available tools for drawing up a new development strategy for the company. The purpose of this study is to consider the foundations of strategic management, its role in the development of an enterprise, as well as to develop recommendations for improving the strategic management of “Energy Save” LLC.

<p>ABSTRACT<br />Lift net fishermen usually use fluorescent lamp as attractor to lure fish. As price of fuel rise, fishermen are forced to find another option to change their attractor into some much lower cost and more energy-save lamp, or in other words, to change into LED lamp. This research are providing evidence that sunked LED lamps can be utilized as a helper tools, and also determined the best time for catching fish in the lift net. Two lift net used in this research, one of them used sunked LED lamps and the other used ordinary fluorescent lamps. Lift net are operated as long as 20 nights, with four catching times per night, between 18.00-21.00, 21.00-00.00, 00.00-03.00, and 03.00-06.00. Results showed that LED lamps give a better result with 11 organisms successfully catch (287,6 kg), compared to ordinary fluorescent lamps with only six organisms (238,3 kg). The best time for catching with LED lamps are between 18.00-21.00 (121 kg), while between 21.00-00.00 (67,4 kg), 00.00-03.00 (46,9 kg) and 03.00-06.00 (52,3 kg).<br />Key words: fluorescent lamp, lift net, light emitting diode, Palabuhanratu,sunked lights</p><p>-------</p><p><br />ABSTRAK<br />Nelayan bagan biasa menggunakan lampu fluorescent sebagai atraktor untuk memanggil ikan. Harga bahan bakar yang mahal menyebabkan nelayan harus beralih memakai jenis lampu lain yang hemat energi, seperti lampu LED (light emitting diode) Penelitian bertujuan untuk membuktikan bahwa lampu celup LED dapat digunakan sebagai alat bantu penangkapan ikan pada bagan dan menentukan waktu operasi penangkapan terbaik. Dua bagan digunakan dalam penelitian ini. Masing-masing menggunakan lampu celup LED dan lampu fluorescent. Bagan dioperasikan selama 20 malam. Dalam 1 malam dilakukan 4 kali penangkapan, yaitu antara jam 18.00-21.00, 21.00-00.00, 00.00-03.00 dan 03.00-06.00. Hasil penelitian menunjukkan bahwa penggunaan lampu celup LED pada bagan menghasilkan 11 jenis organisma tangkapan seberat 287,6 kg, atau lebih banyak dari lampu fluorescent sejumlah 6 organisma (238,3 kg). Adapun waktu penangkapan terbaik pada bagan yang menggunakan lampu LED adalah antara pukul 18.00-21.00 yang menghasilkan tangkapan seberat 121 kg, sedangkan 21.00-00.00 (67,4 kg), 00.00-03.00 (46,9 kg) dan 03.00-06.00 (52,3 kg).<br />Kata kunci: lampu fluorescent, bagan, light emitting diode, Palabuhanratu, lampu celup</p>
