It can give the perfect adaptation that music adds visual aesthetic feeling and light, can allow people enjoy more fully the enjoyment that music is brought, it has not only solved in prior art with dazzling, the dazzling problem of the light of LED lamp light distribution device, and, soft the closing of institute's isolychn, can arbitrarily convert outward appearance, have more practicality.
Operation principle of the present utility model:
EL (electron luminescence) cold light film lamp 7 and drive IC, to produce AC field by being added in the alternating voltage at cold light film lamp 7 the two poles of the earth, the electronic impact fluorescent material being excited by electric field causes the jump, variation of electron energy level, compound and a kind of physical phenomenon of launching high efficiency cold light, i.e. electroluminescence phenomenon.EL cold light lamp sheet (ELLamps) is exactly to utilize above-mentioned principle, the electroluminescence thin slice of making by special process.
Its main electrical characteristic is: operating voltage 30～250VAC; Operating frequency 50～5000Hz; Maximum operating currenbt 0.05mA/cm2 (110V400Hz); Maximum power dissipation 6mW/cm2 (110V400Hz).EL cold light lamp sheet can produce any size and figure, flexible, paste and hang.Light is evenly soft, and luminous efficiency is high, low in energy consumption, and does not produce heat when luminous, containing ultraviolet ray.Ultra-thin (0.12～0.4mm), lightweight, the life-span long (>25000H).
EL cold light film lamp 7 common drive IC mainly contain DJ3009, IMP803, SB6540, SM8141, SP4403, ST1681, D356B etc., and the SP4403 with U.S. HN company briefly introduces below, and its equivalent electric circuit as shown in Figure 2.
SP4403 is a input direct-current 1.8V～6V, and the direct current that is output as ac high-voltage is delivered the IC transducer of stream.It can provide power supply more than 160Vp-p, is specially adapted to drive cold light film lamp 7.It only needs an external inductance to produce high pressure, and an external electric capacity is for regulating the frequency of oscillator.Can be widely used on low power portable product, on the portable equipment of PDA, mobile phone, remote controller and use LCD.
The pin function that subordinate list 1 is SP4403.The major parameter of SP4403 is: operating voltage 1.8V～6V; Operating current (VDD=3V) 20mA～30mA, quiescent current 0.03uA-1uA; Accompanying drawing is typical application circuit, changes capacitor C osc in figure, can change output frequency, and the brightness of EL sheet improves along with the increase of frequency of oscillation and voltage.Increase capacitor C osc, frequency of oscillation will decline, and supply current and output voltage rise, and brightness can first increase conventionally, but can decline after maximum.Suggestion span 150pF～400pF, generally, when 200pF, frequency of oscillation is 400Hz left and right, and during 300pF, frequency is 300Hz left and right, and now effect is better.It should be noted that the increase along with capacitor C OSC, the output voltage of EL pin is to have increased, but sometimes because EL frequency of oscillation decline brightness reduces on the contrary.Inductance in figure, has a best inductance value conventionally to different EL sheets, while adjusting the brightness of EL sheet, can first regulate inductance, then determines capacitance.Conventionally increase inductance value, operating current reduces, and power consumption declines.Larger EL sheet, inductance suitably strengthens, then the electric capacity of arranging in pairs or groups, but will note the relation balance between operating current and output performance.The internal resistance of inductance is less, and the conversion efficiency of IC is higher, and the EL lamp brightness driving in identical situation is also higher.Suggestion span is 470uH～3.3mH.Consider the relation of power consumption and brightness,, according to different application and EL sheet, select suitable combination.
Flasher of the present utility model and audio frequency Play Control circuit 4 have two kinds of connected modes:
The first is that the input of the output of audio signal and the drive IC of cold light film lamp 7 joins, and the output of drive IC is controlled.
