Abstract
The invention relates to an LED (light-emitting diode) display screen which comprises a housing as well as a PCB and a drive power supply mounted in the housing, wherein LED lamp beads are arranged on the front surface of the PCB; a radiating plate is arranged on the back surface of the PCB; a plurality of ventilating pipelines extending to the peripheral side of the housing are arranged on the radiating plate; the two ends of each ventilating pipeline are mutually communicated with openings which are respectively formed in the radiating plate and the housing; the drive power supply is arranged on the middle part of the back surface of the radiating plate; and a supporting post perpendicularly extending towards the outside of the housing along the side surface of the radiating plate is further arranged on the back surface of the radiating plate. The LED display screen is simple and practical in structure; a through ventilating pipeline is arranged on the inner part of the display screen for mutually communicating spaces inside the display screen, so that convection is reinforced, and radiating effect is good; and the LED display screen is energy-saving, is environmentally-friendly, and is wide in use.
Description
Technical field
The present invention relates to LED technology field, be specifically related to a kind of LED display.
Background technology
LED is the abbreviation of light emitting diode, is a kind of solid matter that can convert electrical energy into luminous energy, due to the advantage of its energy-conserving and environment-protective, replaces conventional light source just gradually at present, and the multiple fields in productive life are widely used.But current used LED display, can produce a large amount of heats after long-term work, these heat accumulations, in the display module of sealant pouring and sealing, cause amount of localized heat to gather, and the luminous intensity of LED chip and luminescent lifetime all can be decayed.Meanwhile, high temperature also can cause adverse effect to circuit board, causes the decline of display screen total quality, reduces its working life and display effect.
Summary of the invention
The object of the present invention is to provide a kind of LED display, this display screen good heat dissipation effect, long service life.
For achieving the above object, present invention employs following technical scheme: comprise housing and the PCB that is arranged in housing and driving power, the front of described PCB is provided with LED lamp bead, the back side of PCB is provided with heat sink, described heat sink is provided with multiple ventilation shaft extended to housing week side, the two ends of described ventilation shaft are by being separately positioned on the perforate mutual conduction on heat sink and housing, described driving power is arranged on the middle part at the heat sink back side, and the back side of described heat sink is also provided with the support column along its lateral vertical to housing extension.
Described housing is made up of lampshade and drain pan, and the sidewall of described drain pan is provided with the louvre be connected with PCB.
Described ventilation shaft is arc, and the ventilation shaft sidewall of this arc is also provided with multiple ventilating opening.
As shown from the above technical solution, LED display of the present invention, simple and practical, by arranging in display screen inside the ventilation shaft run through, the space of display screen inside being interconnected, adds strong convection, good heat dissipation effect, and energy-conserving and environment-protective, of many uses.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention will be further described:
As shown in Figure 1, the LED display of the present embodiment, the PCB 1 comprising housing and be arranged in housing and driving power 2, the front of PCB 1 is provided with LED lamp bead 3, the back side of PCB 1 is provided with heat sink 4, heat sink 4 is provided with multiple ventilation shaft 5 extended to housing week side, the two ends of ventilation shaft 5 are by being separately positioned on the perforate mutual conduction on heat sink 4 and housing, driving power 2 is arranged on the middle part at heat sink 4 back side, and the back side of heat sink 4 is also provided with the support column 6 along its lateral vertical to housing extension.
Further, this housing is made up of lampshade 71 and drain pan 72, and the sidewall of drain pan 72 is provided with the louvre 721 be connected with PCB 1.
Further, ventilation shaft 5 is arc, and ventilation shaft 5 sidewall of this arc is also provided with multiple ventilating opening 51.
Above-described embodiment is only be described the preferred embodiment of the present invention; not scope of the present invention is limited; under not departing from the present invention and designing the prerequisite of spirit; the various distortion that those of ordinary skill in the art make technical scheme of the present invention and improvement, all should fall in protection domain that claims of the present invention determines.
