Embedded driving control chip generally all is to adopt four circuits to form a transmission channel to come transmission of control signals in the prior art, when adopting four circuits to connect with flexible cord, two input heads are generally arranged, two deliveries, each one of power connection and Signal connector, joint can cause fault rate to raise too much like this, and reliability is low; Four signals carry out cascade, and the size of pcb board is had very large restriction, for little pcb board, easily cause short circuit, and the problem such as go offline; The signal phase mutual interference of four signal lines causes the cascade limited length.
Summary of the invention
The present invention is in order to solve deficiency of the prior art, to have proposed especially a kind of signal simple in structure, the stable Projecting Lamp of transmission.
The technical solution adopted in the present invention is: a kind of LED Projecting Lamp, the support that comprise base, is connected with base and the lamp body that is connected with support, lamp body comprises lamp housing and the pcb board that is installed in the lamp housing, and be provided with on the pcb board: the LED luminescence unit comprises at least one light emitting diode; Drive control chip, control LED luminescence unit is luminous; With the direct-connected positive source circuit of LED luminescence unit and with drive the direct-connected power cathode circuit of control chip; Described driving control chip is single wire transmission drive control chip, and this chip is by a signal controlling circuit input control signal, and the LED luminescence unit that directly drives on the described pcb board of control is luminous.
Described single wire transmission drive control chip is the single wire transmission drive control chip that carries PWM.
Described single wire transmission drive control chip has the deixis of reporting an error, when chip makes a mistake, and chip output error index signal.
Described lamp housing back is provided with fin, and this fin can be one-body molded with described shell, also is connected with the conduction of housing heat after the moulding separately.
Described LED luminescence unit comprises a kind of or any combination in red light emitting diodes, green LED and the blue LED.
Described single wire transmission drive control chip is encapsulated in the described LED luminescence unit.
Described Projecting Lamp lamp body is strip, circle or oval.
As can be seen from the above technical solutions, the present invention has following beneficial effect: Projecting Lamp of the present invention has adopted single wire transmission drive control chip, make four of signal control line routes become one, joint advances scene 2 by two and changes one-in-and-one-out into, reduced connector quantity, improved reliability, pcb board can be set to minimum, make the Projecting Lamp circuit very simple, Projecting Lamp integral body is frivolous.
