Description
Technical field
The utility model relates to a kind of LED display, is applied particularly to taxi top and carries out information display.
Background technology
The advertising display of current taxi top is popularized, concrete, mostly adopt LED screen to form roof display screen, but traditional roof display screen is single-sided structure, namely one side display, when the LED display of direct sunlight roof, the light of reflection is easy to make people not see ad content, affects identification; We also further study the LED display structure for taxi top, we find that the temperature in LED display assembly is uneven, traditional radiator structure is only considered finned and is arranged bleeder vent, heat radiator is passive heat radiation structure, in time fast cooling can not be carried out in region high for temperature, general damage all arises from high temperature dot; Although can increase heat-sinking capability after arranging bleeder vent, be not significantly durable, once rain-impact that is rainy or carwash, inside will be damaged; And present LED display integral plaster is contained in roof, bottom is airtight, and the heat-sinking capability of bottom is very poor.
Utility model content
Technical problem to be solved in the utility model is for above-mentioned deficiency of the prior art, provides a kind of LED display assembly for taxi top, can double-sided advertisement, and identification is high simultaneously, and radiator structure is reliable, resistance to rain-out; Long-range wireless messages can be realized and show control.
The utility model solves the technical scheme that its technical matters adopts: for the LED display assembly of taxi top, comprise the shell be made up of metal pedestal and printing opacity face shield; Former and later two display surfaces of described shell are inclined-plane, and cover top portion is surface level; Two display surfaces one towards headstock, a facing tailstock; Be provided with double-layer PCB board in shell, two mounting surface of double-layer PCB board are provided with LED display unit; On two display surfaces of described shell, the top of corresponding each LED display unit is provided with light barrier, and light barrier both sides turn down formation flanging downwards; On two display surfaces of described shell, the uniform pit being provided with pyramid-shaped of the part except light barrier and flanging thereof; The surface level of described cover top portion be arranged in parallel multiple top heat dissipation sheet, and top heat dissipation sheet is parallel with length over ends of body direction;
The lower surface of described metal pedestal is evenly equipped with radiating fin, and the two ends of metal pedestal lower surface connect for being fixed on the base on roof; Described metal pedestal is aluminum alloy seat, described radiating fin and metal pedestal one-body molded; Described shell is airtight, enclosure be provided with fan, the blowing direction of fan is perpendicular to length of wagon direction;
Be provided with power supply in described base, power supply is connected with driving circuit, and described driving circuit is connected with control card, and described control card connects described LED display unit and GPRS module, and GPRS module is connected with antenna.
Further: two inclined-planes of described shell are printing opacity acrylic board, the end face of shell is aluminium sheet.
A kind of LED display assembly for taxi top described in the utility model, it has the following advantages:
1, adopt double-layer PCB board to realize the Presentation Function of the LED display unit on two sides, double-sided display, identification is high, and advertising results are better; The display surface of the LED display unit that shell two sides is corresponding is inclined-plane, reduce windage, simultaneously, inclined-plane is arranged light barrier and flanging to stop that LED display unit wastes light upward, light is made to be concentrated on dead ahead or below, the fiber-loss of LED display unit is reduced, and identification increases; Meanwhile, adopt the surface on inclined-plane to arrange the mode of pyramid-shaped pit to realize the diffuse reflection of light, namely, sunlight is radiated on inclined-plane can not reflect the dazzling light in place, but reflects away with irreflexive form, ensure that the identification of double-sided display;
2, radiator structure of the present utility model is very reasonable and creative, concrete, and the heat radiator of cover top portion is convenient to car and is taken away by heat under steam, adds radiating effect; Metal pedestal inherently can pass to heat in time, radiating fin below metal pedestal dissipates, and metal pedestal is arranged on base due to two ends, distance roof maintains a certain distance on the whole, the heat-sinking capability of this space when type of motor car is very strong, and is provided with fan due to enclosure, and all even heat can be distributed in enclosure by fan, the existence of timely elimination high temperature dot, final unified discharge is lowered the temperature.
3, the utility model realizes controlled in wireless by the assembly arranging controlled in wireless on base, concrete, can be simple and efficient carry out Wireless Data Transmission by GPRS, and relevant information is shown on the display screen of LED display unit composition of taxi top, it is convenient to control, more intelligent, make the LED display of taxi top can play larger effect, play the effect of prior information display.
