technical field

The utility model relates to a structure of a traffic signal device, in particular to a structural design for displaying at least two color lights in a single lamp, and through the structure, the man-hour cost and occupied volume during manufacture are reduced, making installation and easier to use.

Background technique

The traditional traffic signal device uses a light bulb as a light source. When the light bulb is turned on, it illuminates the red, yellow, and green light-transmitting panels at the front end. Through the combination of three lights, three lights of red, yellow, and green are formed. A traffic signal device; however, in recent years, with the advancement of science and technology and the reduction in the price of light-emitting diodes (LEDs), the current traffic signal device changes the light source into light-emitting diodes of different colors, but the light-emitting diodes are small in size and low in brightness , so it is necessary to arrange nearly a hundred pieces in each lamp to provide the required brightness requirements.

With regard to the above structure, according to the research and observation of the creator, in fact, only one color light (such as red or green light) is lit in a single time, and the yellow light is lit for the shortest time; and the above three colors are grouped together The lamps and lanterns take up space, and cause the surrounding scenery to be covered, obstructing the view of the city, and are more likely to fall off and break due to wind and weather, so it is necessary to improve it.

Utility model content

The main purpose of the utility model is to improve the lack of the front row, effectively reduce the volume and weight of the traffic signal device, and make the installation and use more convenient.

The secondary purpose of the utility model is to effectively reduce the man-hour cost of manufacturing, and at the same time take into account the effects of energy saving and power saving.

In order to achieve the aforementioned purpose, the technical means of the present utility model is to provide a traffic signal device that displays at least two colors of light in a single lamp, including: a housing, at least one side of which has a light-transmitting portion; a display module, It is located in the casing and has a circuit board. A plurality of light-emitting diodes are provided on one side of the circuit board, and the plurality of light-emitting diodes have at least two kinds of color light displays. They are arranged on the circuit board and correspond to the light-transmitting part. The power plug port selectively lights up the light-emitting diodes of different colors; and the other side of the circuit board is provided with a heat sink, which is thermally bonded with the bottom surface of the housing; A convex spherical surface, a light guide column is provided on the inside of the mask facing the light emitting diode, and the end surface adjacent to the bottom edge of the light guide column and the light emitting diode is a concave arc surface.

Through the above technical means and structural features, the traffic signal device of the utility model can effectively reduce the cost and occupied space, reduce the probability of being damaged by wind and bad weather, and at the same time achieve good illuminance and display brightness.
