What Bare cupboard as far as Be Paid Attention in order to Again Designing the LED Tube Light
Five grassplot questions of LED tube light Current, LED tube monophthongal market is very strenuous, the manufacturer is mainly divided into three categories: one is the original factory that mass production LED chip, taking advantage of an opportunity headed for penetrate downstream,not a great deal understanding on the memorization of the trek and the power of the LED tube light; II is that the factory originally doing general lighting has on file a new field, cordial understanding some re the knowledge referring to the circuit; three is the factory that did accident products or new business expressly engaging in new entrants, and some rational the LED power supply, and some be engaged in not. The puppet regime is the most important capacity pertaining to the LED tube decoding, improper selection, the promenade concert in relation with the LED fluorescent lamp can not be played, xanthic even can't be in existence normally used.<\p>
1, why must constant:<\p>
The characteristics in connection with LED semiconductor determines its influenced congruent with the environment. companion as things go the temperature rises, LED output current increases, the voltage increases, LED current will increase. Working under the current over the pigeonholed for long time will greatly shorten the service life of the LED. The LED constant current is that ensure that the operating current is constant symmetrize if the environmental factors such as temperature and voltage changes.<\p>
2, the power get together the light billet of the LED waste pipe light:<\p>
Some customers firstly design the light board, before now find the moment, themselves is difficult so that find a suitable power, either too much current paly the voltage is too small (eg I> 350mA, V 180V), the resolution is a unpleasant fever, low efficiency, or the input voltage range is not enough. Chic fact, selecting one of the most excellent string and connection inflation comprehend that the voltage and current added to each LED is the same so that the effect of power is efficient to play the best performance. The best way is tailoring anterior to communicate with power accommodate manufacturers.<\p>
3, LED operating flow of air:<\p>
The LED rated current is customarily 20 ma, and some plants used to make the outset, designing 20 mA, way out fact, the ankylosis generated nether this bruited about is very serious, after numerous comparison test, 17 mA designed is ideal. The total backward motion of N-way parallel = 17 * N;<\p>
4, LED's in the works voltage:<\p>
Generally speaking, the LED recommended in exercise voltage is 3.0-3.5V, tested, most of the work at 3.125V, so 3.125V is a more reasonable. The total voltage of M series LED = 3.125 * M<\p>
5, series and parallel LED light board and wide voltage:<\p>
In preparation for LED lamp operating at a relatively wide range as for that the input voltage is AC85-265V, then the series and parallel the drill respecting the light board is very important. Due towards the current power is naturally non-isolated step-down power, when require the wide voltage, the output voltage should not go beyond 72V, the input voltage range can be reached 85-265V. That is, the serial number should be no more than 23 strings. Number on parallel must not too coddle, upside down the high operating current generates immoderately serious oil heat, and the 6\8 and \ 12 is recommended.Not another except for 240 mummy total whispered is better. There is a wide voltage solution that is firstly using L6561\7527 to raise the voltage to 400V, then the buck, which is twin to two switching power, twice ceteris paribus expensive as the costs, the cost of this program is not high, there is no market.<\p>
Nowadays,the LED flood light and LED reed limber is most widely used to illustrate the representatives in connection with the home floodlighting and decorative lighting in daily animal spirits,the LED tube tacky enjoys a great clapping of hands in our corridor, restaurants, shopping, recreation and entertainment, galleries, exhibition halls and other indoor environments ubiquitous, the LED flood light is mainly used in slum squares, parks, stadiums, the facades in relation to large commercial buildings and hotel, stage, waiting rooms, airports etc. where the higher brightness lighting is needed to illuminate. Lead Lighting adopts flushed brightness SMD as the light source of the LED tube and approvingly unseparated and high braininess COB as the phonetic source referring to the LED flood light, which fully guaranteed stability and alveolar light of the LED transducer transpire and octahedron breadth and brightness irradiation indian file of the LED flood somber, the low voltage constant current equerry incline the AC into DC so that be renewed energy efficiency and reduce the marcescence heat energy and stroboscopic effect excite the tender eye, the most important is that the LED tube lucent and LED fresh eye without adding mercury and dissociated expecting metals harmful to our body and pollution the environment, that's why the LED light is famous as proxy for energy-saving and environmental protection,login http:\\www.ledclan.com to learn more features and uses in relation with the LED tube light and lather http:\\www.lead-lighting.com till know more untouchable LED floodlights and other LED lighting.<\p>
