Abstract
This invention provides a TV with status pilot lamp composed of a shell, pilot lamp, MCU and a control circuit characterizing that the said pilot lamp includes at least two designed on the shell, MCU output/input end is connected with the pilot lamp driver, output of which is connected with the pilot lamp directly which is LED color lamp set on the front panel of the shell. The said panel is linked to a frog, the display is the opened mouth of the frog, there are two upward projecting semicircles as two eyes of the frog, the two said pilot lamps are set at the frog's eyes, indicating many different working conditions.
Description
Technical field
The invention belongs to the improvement of television set, is a kind of television set with status indicator lamp specifically.
Background technology
The indicator light of television set has only the holding state indicator light at present, and along with the development of television set, its function is more and more, existing indicator light can not be finished the indication of multiple operating state, as: normal operating conditions, normal holding state, timing start-up state, game state, watch state, lock-out state etc. in limited time, this makes troubles to users.
Summary of the invention
Purpose of the present invention provides a kind of television set with status indicator lamp, and indicator light can be indicated multiple operating state, and the indicator light position is provided with rationally, shows clearly, directly perceived, is convenient to differentiate.
The objective of the invention is to be achieved through the following technical solutions: a kind of television set with status indicator lamp, mainly form by casing, indicator light, TV central processor MCU and control circuit thereof, be characterised in that described indicator light is at least two, be arranged on the housing, the output of TV central processor MCU/input connects lamp driver, and the output of lamp driver directly links to each other with indicator light.
Described driver is made up of transistor circuit, the base stage of triode D is connected to MCU output/input port by a resistance R 1, the collector electrode of triode is connected to positive source by another resistance R 2, and penetrating of triode collects an end that is connected to indicator light, the other end ground connection of indicator light.
Another technical scheme is: described driver is made up of transistor circuit, the base stage of triode is connected to MCU output/input port by a resistance R 1, the emitter-base bandgap grading of triode is connected to ground by another resistance R 2, and collector electrode is connected to an end of indicator light, another termination positive source of indicator light.
Described indicator light is the colored indicator light of LED, and is arranged on the panel in casing front.
Described casing is the frog shape, and display screen is open big mouthful an of frog, and it is two eyes of frog that there are two semicircles that raise up the panel upper edge, and described indicator light is two groups and is arranged on two eyes positions of frog respectively.
The present invention compared with prior art has many advantages and good effect:
1, indicator light of the present invention has a plurality ofly, and by level and pulse that the TV central processor MCU changes from the output of different pin real-time dynamicly, makes the various operating states of TV be shown to the user by colored indicator light very intuitively.By software design, can be at different states, number and state that indicator light shows are all different, and the demonstration of lamp can be a stabilized illumination, also can glimmer, walk about, and more helps User Recognition and operation.
2, described casing is the frog shape, and display screen is open big mouthful an of frog, and it is two eyes of frog that there are two semicircles that raise up the panel upper edge, and described indicator light is two groups and is arranged on two eyes positions of frog respectively.Like this, it is reasonable, eye-catching that the position of indicator light is provided with, and can cause children's interest and attention especially, is convenient to distinguish.
Description of drawings
Fig. 1 has the indicator light control circuit figure of the television set embodiment of status indicator lamp for the present invention;
Fig. 2 for the present invention have status indicator lamp the indicator light control circuit figure of another embodiment of television set;
Fig. 3 for the present invention have status indicator lamp the front view of television set complete machine.
Embodiment
Below in conjunction with drawings and Examples the present invention is described in further detail.
Referring to 3, a kind of television set with status indicator lamp, mainly by casing 4, indicator light 3, TV central processor MCU 1 and control circuit thereof, described casing 4 is the frog shape, display screen is open big mouthful an of frog, it is two eyes of frog that there are two semicircles that raise up the panel upper edge, and described indicator light is two groups and is arranged on two eyes positions of frog respectively.Described indicator light is the colored indicator light of LED.
Figure 1 shows that embodiment 1: the output of TV central processor MCU 1/input connects lamp driver 2, and the output of lamp driver 2 directly links to each other with indicator light 3.Described driver 2 is made up of transistor circuit, triode D (D1 ... Dn) base stage is by a resistance R 1 (R1-1 ... R1-n) be connected to MCU output/input port, the collector electrode of triode is by another resistance R 2 (R2-1 ... R2-n) be connected to positive source, penetrating of triode collects an end that is connected to indicator light 3, the other end ground connection of indicator light 3.
Figure 2 shows that embodiment 2: the output of TV central processor MCU 1/input connects lamp driver 2, and the output of lamp driver 2 directly links to each other with indicator light 3.Described driver 2 is made up of transistor circuit, triode D (D1 ... Dn) base stage is by a resistance R 1 (R1-1 ... R1-n) be connected to MCU output/input port, the emitter-base bandgap grading of triode is by another resistance R 2 (R2-1 ... R2-n) be connected to ground, collector electrode is connected to an end of indicator light 3, another termination positive source of indicator light 3.
The quantity of indicator light 3 is by how many decisions of the operating conditions of TV set of needs indication, can be a kind of the corresponding indicator light 3 of state, also can adopt the form of combination, indicator light 3 can be single led, also can be LED group, the luminous form of indicator light 3 can adopt stabilized illumination, flicker or take turns various ways such as bright.When the operating conditions of TV set of needs indications more for a long time, if adopt the I/O port of a MCU1 to connect a lamp driver 2, the MCU I/O port that takies is just many, at this moment also can take coded system, this will add the one-level multi-channel electronic switch in lamp driver 2 fronts.
