Detailed Description

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby. It is to be noted that unless otherwise specified, technical or scientific terms used herein shall have the ordinary meaning as understood by those skilled in the art to which the present invention belongs.

The first embodiment is as follows:

as shown in FIG. 1, the signal indicating lamp comprises a base 1 and a plurality of L ED lamps 2 arranged on the base, wherein the L ED lamps 2 are distributed on the base 1 in an array;

specifically, the developer can set L ED lamps at corresponding positions to be lit according to the pattern to be displayed, L ED lamps can display various colors, such as red, yellow, green, and the like, L ED lamps can adopt a point contact type diode, such as a full color RGY common cathode diode of Yada, which has 4 pins, 1 pin outputs high level of red, 2 pin outputs cathode, 3 pin outputs high level of green, and 4 pin outputs high level of yellow, and L ED lamps can also be realized by using a common diode.

The signal indicator lamp also comprises a processor arranged on the base, and the control ends of the processor are respectively connected with L ED lamps.

Specifically, L ED lamps are driven by the processor, L ED lamps are controlled to be turned on or off, and the processor can adopt common microprocessors such as a single chip microcomputer and an FPGA.

The signal indicator lamp is low in cost.

Further, each plurality of L ED lamps 2 forms a L ED lamp loop;

as shown in FIG. 2, the signal indicating lamp further comprises a processor and a plurality of decoders U1 arranged on the base, the number of the decoders U1 is the same as that of the L ED lamp loops, the control end of the processor is respectively connected with the input end of the decoder, and the output end of each decoder is respectively connected with the L ED lamp in each L ED lamp loop.

Specifically, a decoder controls the turn-on or turn-off of the L ED lamp on an L ED lamp loop since the signal indicates a higher number of L ED lamps in the lamps, the decoder is used to drive the L ED lamps, e.g., 38 decoder, so that the processor can drive more L ED lamps, the 38 decoder is used to drive the L ED lamps in FIG. 2, so that the processor only needs to provide 3 ports to drive 8L ED lamps, wherein the decoder can also use n-line-2 ^ n line decoders.

For example, in the aspect of traffic signals, the sequential display of red, yellow and green can be realized, the display of various indication graphs (such as directional arrows, analog forms and the like) and the display of waiting, passing and interval time can also be realized, and various combined displays can be realized.

Example two:
