As shown in the figure is the infrared automatic faucet controller circuit. The control circuit includes a transmitting circuit and a receiving and decoding control circuit. The transmitting circuit is composed of a multi-vibrator and an infrared emitting diode; the receiving circuit includes an infrared receiving tube D1 and D2, an operational amplifier IC2 (CA741), an audio decoder IC3 (LM567), an AC solid-state relay IC4 (SP110), a power supply circuit, and the like. composition. In the transmitting circuit, the multivibrator is composed of IC1 (555) and R1, R2, C1, etc., and its oscillation frequency is f=1.44/(R1+2R2)C1, and the frequency corresponding to the parameter shown in the figure is about 40 kHz. The oscillating output signal drives the LEDs 1 to 3 of the TLN 104 type to operate, thereby generating an infrared pulse modulated wave.
Indoor Rental Die-Cast 640x640
Indoor Led Display Sign improved competitive price with perfect effect and high quality. The Large Led Display Die Casting Aluminum Cabinet size is 576x576mm for Indoor Usage, Best resolution for Led Stage Screen P2.5mm P3.076mm P4mm P5mm, Led Display Sign Panels to achieve uniform brightness and driving chip of high consistency and pixel brightness consistency.
The rental led screen showed more uniform and more clear. When choose 640mm x 640mm Led Display Rental Cabinet, it can depend on different price for P5 P4 P3.076 P2.5, because all their module size can be 320x160mm, it is easy to make Die Cast Aluminum Cabinet.
Light and slim seamless connection design die-casting aluminum cabinet, it`s only 90mm in thickness which can achieve better wall mounted effect The cabinet is light, it`s only 28kg/sqm which is labor saving.
1) Stronger protection: LED chips are welded on the PCB board directly, then do encapsulation. It has excellent protection capabilities.
2) Higher reliability and stability: simpler process on material using and producing than SMD, so it has higher performance on heat dissipation to prolong life span.
3) Larger viewing angle: has larger viewing angle and is easy to control the loss of light refraction.
Easy Installation: magnesium alloy cabinet design and fast lock make the installation, transportation, maintenance easier
Lightweight: only 30kgs, saving workforce and transportation cost
High Waterproof Level: IP65 for rear and back side, fit for naked installation without decoration.
Adopt dual service of black kingkong series among core techniques, free back service path for all kinds of installation surroundings.Broadcast level color scale, color temperature and brightness adjustable intelligentizedly, smooth color, high color ratio, nature pictures.
