Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a multi-lamp color-change signal lamp, and more particularly to a multi-lamp color-change signal lamp having a small volume, low cost, and easy to manufacture, and having abundant application functions.

[0002]

[Prior art]

 As shown in FIG. 1, the conventional thin light emitting diode 2 signal light adopts a multilayer display system. By combining the light emission principle of the light emitting diode 2 with the multi-layered light cover 1 of different colors, it is possible to display light of various colors.

[0003]

[Problems to be solved by the invention]

 However, the conventional signal light shown in the figure employs a combination of the multi-layered light cover 1, so that the volume of the signal light by the photodiode 2 is considerably large due to its structure. In addition, the light cover 1 of each layer employs a large number of light emitting diodes 2, so that the production cost is enormous and troublesome.

The present invention has been made in view of these circumstances, and in the structure of a thin light emitting diode signal light, a transparent light cover is adopted only one time, and several light emitting diodes are installed in the transparent light cover. It emits lights of various colors, so there is no need to rely on the color of the light cover. By using only one transparent light cover and several light emitting diodes, light beams of various colors can be projected in all directions. Therefore, it is possible to provide a multi-lamp color-change signal lamp having abundant application functions while being compact and inexpensive and easy to manufacture.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention provides a multiple lamp color change signal lamp having the following configuration.

It is mainly composed of a nut, a washer, a light cover lid, a transparent light cover, a lighthouse body, and several light emitting diodes installed on an upright rectangular circuit board of the lighthouse body.

[0007] Three power lines, a red line, a ground line, and a green line, are installed in the lighthouse body.

When the switch is switched to the contact b, the current flows from the red line through the electric obstruction, flows into the light emitting diode, emits red light, and when the switch is switched to the point c, the electric current passes through the electric obstruction from the green line. Then, the light flows into the light emitting diode to emit green light. When the switch is switched to contact a, one end of the current flows through the yellow light common power supply line, through the diode, further through the red line, through the electrical obstruction, and flows to the light emitting diode. And the opposite end of the current passes through the diode, further passes through the electric block via the green line, flows into the light emitting diode, and emits yellow light.

When the light emitting diode emits light of any kind, the light is projected in all directions through one layer of the transparent lamp cover, and the switch is set to a contact, b contact, c contact depending on the diode design of the circuit. In either case, the current flows and the line is open.

[0010]

[Embodiment of the invention]

 As shown in FIGS. 2 and 3, one embodiment of the present invention mainly includes a nut 3, a washer 4, a light cover lid 5, a transparent light cover 12, a lighthouse body 6, and an upright rectangular circuit board of the lighthouse body 6. It is composed of several light emitting diodes 2 installed on the light emitting diode 13.

The light emitting principle of the light emitting diode 2 will be described below.

As shown in FIG. 4, the photodiode 2 has three contacts, a contact A14, a contact B15, and a contact C16. When it is desired that the light emitting diode 2 emit red light 19, the contact B15 is connected to the ground 23 and the contact A14 is connected to the positive wire 22.

Next, as shown in FIG. 5, when it is desired that the light emitting diode 2 emits green light 20, the contact B 15 is connected to the ground 23, and the contact C 16 is connected to the positive wire 22.

Subsequently, as shown in FIG. 6, when it is desired to cause the light emitting diode 2 to emit yellow light 21, the contact B 15 is connected to the ground 23, and the contact A 14 and the contact C 16 are connected to the positive wire 22. .

In the lighthouse main body 6, three power lines, a red line 7, a ground line 8, and a green line 9, are provided.

As shown in FIG. 7, when the switch 18 is switched to the contact b, a current flows from the red wire 7 through the electric block 11 to the light emitting diode 2 to emit red light.

When the switch 18 is switched to the c-contact, a current flows from the green line 9 through the electric block 11 to the light emitting diode 2 to emit green light.

When the switch 18 is switched to the “a” contact, one end of the current passes through the yellow lamp common power supply line 17, passes through the diode 10, further passes through the red wire 7, and passes through the electric block 11, and the light emitting diode 2 The current, and the opposite end of the current, passes through the diode 10, further passes through the electric block 11 via the green line 9, flows into the light emitting diode 2, and emits yellow light.

As described above, when the light emitting diode 2 emits any kind of light, the light is projected through the transparent light cover 12 in all directions. Also, depending on the design of the diode 10 of the circuit, the current flows even when the switch 18 is switched to any one of the points a, b and c, and the line is opened.

[0020]

[Effect of the invention]

 As described above, according to the present invention, since the adoption of the multiple light color change signal light transparent light cover is used only in one layer, the volume can be made very small, and furthermore, several light emitting diodes are used. By simply doing so, it is possible to emit light of various colors, which has the effect of being inexpensive, easy to manufacture, and having a wide variety of applied functions.
