Abstract
The utility model provides a taxi top lamp with dynamic scan display, which is characterized in that a front dot matrix display screen is fixed on a front transparent piece, the front transparent piece is fixed on an upper cover; a rear dot matrix display screen and a rear transparent piece are fixed together through an upper cover and a lower cover; the upper cover and the lower cover are connected together through an installing bracket, and the taxi top lamp with dynamic-scan LED dot matrix is arranged on the top of the car by the installing bracket. The utility model adopts ultrahigh bright dot matrix diode to form the display screen; is provided with an embedded processor, and is provided with an external communication interface. The content to be displayed can be transmitted in real time through the gateway of the company; the driver can use the controller with LCD display in the car to modify the content to be displayed on the top lamp of the taxi; the content to be displayed on the top lamp of the taxi can be displayed on the LED dot matrix screen by the dynamic scan display based on a microprocessor. The utility model can indicate the running direction of the taxi and the carriage state of the passengers; and can display text information, such as text advertisement and the like.
Description
Technical field
The utility model relates to a kind of taxi dome lamp of LED dot matrix of dynamic scan, belong to and hire out the car light technical field.
Background technology
Because travelling of taxi often have certain directionality, especially when taxi is relieved,, make things convenient for the passenger to take taxi for the passenger who waits for bus can just can see the direction that taxi travels and the carrying state of taxi a long way off.Taxi also is the carrier of the information flowing in city simultaneously, can show some Word messages.Yet the effect of existing taxi dome lamp is the mark sign of taxi, what have can only use by day, the taxi dome lamp that a kind of round-the-clock taxi dome lamp and a kind of alarm type are arranged in the prior art, lamp and control circuit that round-the-clock taxi dome lamp comprises power supply, lamp socket, is made up of light emitting diode, but it is non-dynamic scan, and the taxi dome lamp of alarm type mainly is made of a warning circuit.Has warning function.
Summary of the invention
The purpose of this utility model is intended to overcome the non-dynamic scan of prior art, proposes a kind of taxi dome lamp of LED dot matrix of dynamic scan, adopts the dynamic scan technology based on microprocessor, shields o'clock sharp wanting content displayed to be shown to LED.Can indicate vehicle heading, carrying state, Word messages such as issue copy.
Technical solution of the present utility model: its structure is that preceding dot matrix display screen is fixed on the preceding Transparent Parts, preceding Transparent Parts is fixed on and covers, back dot matrix display screen and back Transparent Parts are fixed by loam cake and lower cover, loam cake links to each other by mounting bracket with lower cover, and the taxi dome lamp of the LED dot matrix of this dynamic scan is installed on the roof by mounting bracket.
Advantage of the present utility model: adopt super bright dot matrix diode to constitute display screen, embedded micro-processor has external communication interface.Can transmit displaying contents in real time by corporate gateway, also can revise the displaying contents of the ceiling light of taxi by the driver by the controller that has the LCD demonstration in the car, the displaying contents of taxi dome lamp adopts the dynamic scan technology based on microprocessor, shields o'clock sharp wanting content displayed to be shown to LED.Can indicate vehicle heading, carrying state, Word messages such as issue copy.
