Abstract

The utility model relates to a multiple lamp-colour changeable signal lamp, comprising a nut lamp, a gasket, a lampshade cover, a lampshade and a lamp base main body. The utility model is characterized in that the multiple lamp-colour changeable signal lamp is provided with only one layer of transparent lampshade, an erect rectangular circuit board of the lamp base main body is provided with an LED luminous dipolar body, the lampshade is buckled on the lamp base main body, the lampshade is provided with the lampshade cover, and the lampshade cover is fixed through a junction part which is arranged on the rectangular circuit board through a screw and the gasket. Simultaneously, the inner of the lamp base main body is provided with three power cords. One is a green cord, another one is a red cord and the last power cord is a ground cord. A switch is used for switching over to make electricity flow through different power cords through a resistor to the LED to send out lamp lights with different colours of a red light or a green light or a yellow light, etc.

Description

The signal lamp that multiple light color changes

The utility model relates to a kind of signal lamp, is particularly useful for the signal lamp that a kind of multiple light color changes.

As shown in Figure 1, for general thin-type LED (light-emittingdiode) signal lamp 2 commonly used has adopted the multilayer display mode, lampshade 1 and LED principle of luminosity by the multilayer different colours, the light that can show multiple color, but on its structure, because of lampshade 1 array mode that has adopted multilayer, so these LED signal lamp 2 volumes are big, take up space, and this every layer lampshade 1 all must adopt a large amount of LED elements, can send versicolor light, on making, must expend sizable cost, and the cost more time goes to make, so normal round user and manufacture are scolded.

Therefore, how above-mentioned shortcoming is forgone, be the place of the technical difficulties of this creator institute desire solution.

In view of this, this creator is professional attainment and the technical concept that is possessed with itself, through the improvement that studies repeatedly, the utility model is born.

The purpose of this utility model is to provide a kind of signal lamp of multiple light color variation, it is on thin-type LED signal lamp structure, only adopted the layer of transparent lampshade, and be located at the erect-type rectangular circuit board of lamp socket body in the Transparent lamp shade and be provided with the light that a plurality of LED can launch multiple color, must be by the color of this lampshade body, so only used layer of transparent lampshade and a plurality of LED, just can reach multiple color light and throw effect from all directions, and not only volume is little for the signal lamp that this multiple light color changes, seldom take up space and with low cost, make easily, with better function, on using, it has more practical value.

The purpose of this utility model is achieved in that the signal lamp that a kind of multiple light color changes, comprise the nut lamp, packing ring, lamp cover, lampshade and lamp socket body, it is characterized in that: signal lamp is only established the layer of transparent lampshade, and on the erect-type rectangular circuit board of lamp socket body, be provided with the LED light-emittingdiode, lampshade is buckled on the lamp socket body, establish lamp cover on it, and fixed by the junction surface of being located on the rectangular circuit board through screw and packing ring, in the lamp socket body, be provided with simultaneously three power leads, article one, be green line, article one, be that red line and another are grounding jumper, switch through switch, make electric current flow to LED by resistance and send ruddiness through the different electrical power line, the light of different colours such as green glow or gold-tinted.

The utility model has the advantages that:

1, only adopt the layer of transparent lampshade make signal lamp that multiple light color changes not only volume little, seldom take up space.

2, only use a plurality of LED just can reach multiple color light and throw effect from all directions, and making with low cost, easy.

3, tool practicality.

4, tool progressive.

5, value on tool commercial and industrial circles and the industrial community.

Cooperating Figure of description and specific embodiment that the utility model is done detailed an introduction below is described as follows:

Description of drawings:

Fig. 1 is the perspective exploded view of general convectional signals lamp;

Fig. 2 is a block diagram of the present utility model;

Fig. 3 is a perspective exploded view of the present utility model;

Fig. 4-the 1st, the luminous pin scheme drawing of LED;

Fig. 4-the 2nd, another scheme drawing of the luminous pin of LED;

Fig. 4-the 3rd, the another scheme drawing of the luminous pin of LED;

Fig. 5 is the luminous circuit diagram of LED.

Shown in Fig. 2,3, the utility model is made up of nut 3, packing ring 4, lamp cover 5, Transparent lamp shade 12 and lamp socket body 6, and the erect-type rectangular circuit board 13 of lamp socket body 6 is provided with a plurality of LED 2.

Wherein LED 2 principle of luminosity are as follows:

1, shown in Fig. 4-1, LED 2 has three branch connecting pins, and pin A, pin B and pin C are arranged, as desires to make LED 2 to glow 19, except that with the pin B ground connection 23, and pin A is connected positive supply 22.

2, shown in Fig. 4-2, as desire to make this LED 2 green light 20, except that pin B ground connection 23, and pin C connected positive supply 22.

3, shown in Fig. 4-3, desire to make this LED 2 jaundice light 21 again, except that sweeping pin B ground connection 23, and pin A and pin C connected positive supply 22.

Be provided with three power leads in the lamp socket body, article one, be green line 9, article one, be that red line 7 and another are grounding jumper 8, and for example Fig. 5's shows, switch 18 is cut the point to b, make electric current flow to LED 2 by resistance 11 and send ruddiness via red line 7, if this switch 18 is cut the point to c, make electric current flow to LED 2 by resistance 11 and send green glow via green line 9, switch 18 is cut to a point again, via amber light common power source circuit 17, its electric current one end flows to LED 2 via red line 7 by resistance 11 again through diode 10, and the electric current other end flows to LED 2 via green line 9 by resistance 11 again through diode 10, two electric currents flow to LED 2 respectively, make LED 2 send gold-tinted, no matter which kind of light LED 2 sends, when seeing through Transparent lamp shade, reached and throwed effect from all directions, and in diode 10 design of circuit, avoided no matter starting 18 cut to this b point to the c point, the neither state that refluxes that produces that causes of electric current.

In sum, the utility model is being broken through under the previous technical pattern, really reached the effect that institute's desire is promoted, and also non-be familiar with this skill person institute easily full of beard and, moreover, not open before the utility model application, the progressive of its tool, practicality, show the application requirement that has met utility model patent, so propose utility application in accordance with the law.
