Description
Technical field
The present invention relates to the Computers and Communication technical field, relate in particular to a kind of indicating lamp module and method for designing thereof.
Background technology
Existing Ethernet switch, port and corresponding ports indicator light provide two the most basic key elements to the user.Wherein, port is that switch is finished the Media Interface Connector that user data is handled and transmitted; And indicator light is to be used for luminescent device to user's visual indication port work at present state, and the luminescent device that mainly uses of industry is light-emitting diode (LED, Light-Emitting Diode) at present.
The indicator light circuit of realization indicator light demonstration different conditions is made up of indicator light drive signal, indicator light, displacement latch and necessary resistance capacitance, as shown in Figure 1.Wherein, the indicator light drive signal comprises clock signal (LED_CLK) and data-signal (LED_DATA), is produced by indicator light controller (generally being exchange chip); Indicator light adopts Surface Mount red and green color LED, and red and green can be lighted separately, also can be lighted simultaneously.The displacement latch is realized the serial data from " DATA " input is latched into Qn (n=1,2,3......8) by turn, and a plurality of such displacement series of latches can realize bits of data more is latched into separately Qn (n=1,2,3......8) by turn.Resistance between power supply VCC and the LED anode is used for current limliting, can control the brightness of LED by the size of regulating resistance.
After fixed frequency of given LED_CLK, just can realize that by on LED_DATA, producing different data indicator light is to the indication of port status.When the last low level that produces of LED_DATA was latched into Qn, corresponding LED conducting began luminous; When latching high level on the Qn, corresponding LED can not conducting, also just can not be luminous.For example, can stipulate the corresponding red and green color LED light of each port for a switch that possesses 10/100Mbps speed ethernet port.When bright green, represent port working in 100Mbps, hot green double-colored when all bright (this moment, mixed color was orange) expression port working in 10Mbps; When green or orange flicker, represent that port has data transmit-receive.
Design methods existing is indicator light circuit and indicator light controller, external port etc. is arranged on the same mainboard jointly, comparatively common have two kinds of schemes, a kind of is the upper surface (rear of port) that indicator light is positioned at mainboard, by the leaded light post light is guided to the switch front panel.Another is the lower surface (below of port) that indicator light is positioned at mainboard, no longer needs the leaded light post, but directly by the light-conductive hole on the plate in front light is arrived front panel thoroughly.
The common defects of these two kinds of schemes is as follows:
Design efficiency is low: in these two kinds of schemes, for each new motherboard design, indicator light circuit also must be done design iterations one time; And for Ethernet switch, indicator light circuit principle basically identical, if with the independent independent design of indicator light circuit, form a kind of general indicating lamp module that can mate multiple motherboard design, can prevent indicator light putting position mistake in the design iterations process, improve the overall design efficiency of switch.
Indicator light circuit has limited motherboard layout: for example, concerning a switch that has 24 10/100Mbps ports, need 24 red and green color indicator lights to finish the port status indication altogether, just need 48 LED drive signals, connecting line between displacement latch and the indicator light also just has 48, so numerous cablings often need cut or upset the originally complete signal reference layer or the cabling of other signals layers, brings great inconvenience for the placement-and-routing of pcb board.
Limited the switch miniaturization Design: indicator light circuit has limited motherboard layout, and indirect influence is to make the mainboard size further not to be compressed, and is exactly that volume can not further be miniaturized on the present switch overall appearance of final body.
