Abstract
The utility model relates to the technical field of electronic display and provides an improved outdoor LED display screen which is simple in structure, good in heat dissipation effect and long in service life. The improved outdoor LED display screen comprises a box body and a display module arranged in the box body. The box body is composed of a face cover and a shell body which are mutually buckled. The improved outdoor LED display screen further comprises heat dissipation boards. The display module comprises a plurality of display units. Each display unit comprises a circuit board. An LED lamp array arranged in a matrix is arranged on the front face of each circuit board. A circuit module capable of driving one LED lamp array is arranged at the back face of each circuit board. Through holes are formed in each heat dissipation board, wherein each LED lamp array penetrates through the through holes. Each heat dissipation board is arranged at the front face of one circuit board. Pins of LED lamps in each LED array penetrate through the through holes and are welded on one circuit board.
Description
Technical field
The utility model relates to field of electronic display, particularly a kind of modified outdoor LED display screen.
Background technology
LED display is the high-tech product that light harvesting electronic technology, microelectric technique, computer technology and video technique are integrated, its luminous component is to be light emitting diode by LED() be assemblied to form, its advantage is that power consumption is few, brightness is high, operating voltage is low, driving is simple, the life-span is long, the area of stable performance, display screen can be as required by any assembly unit of unit module, fast response time.LED display has remedied the in the past defective of the information publication medium effects such as magnetic turnover panel, neon bulb, change abundant color, pattern with it, realize dynamic display mode, perfect Multimedia and powerful visual impact, the various ways such as information, literal, picture, animation and video are shown, become the epoch-making product of Information Communication, be widely used at railway, civil aviaton, stadiums, conference halls, highway etc.But, existing outdoor LED display screen is under energising operation spontaneous heating and the double action at solar light irradiation, the temperature of box house raises fast, be difficult for heat radiation, long-time application can cause the electronic devices and components accelerated deterioration of outdoor LED display screen, and the decay of LED lamp pearl is accelerated, shortened its serviceable life.
Summary of the invention
Therefore, for above-mentioned problem, the utility model proposes the modified outdoor LED display screen of a kind of simple in structure, good heat dissipation effect, long service life.
For solving this technical matters, the utility model is taked following scheme: a kind of modified outdoor LED display screen, comprise casing and be located at the interior demonstration module of casing, described casing is made of cover and the housing of mutual fastening, also comprise heat sink, described demonstration module comprises some display units, each display unit comprises circuit board, described circuit board front is provided with the LED lamp array that matrix is arranged, described back of circuit board is provided with the circuit module of driving LED lamp array, offer the perforation that wears for LED lamp array on the described heat sink, the pin that described heat sink is located at LED lamp in circuit board front and the LED lamp array passes piercing welding on circuit board.
Further, the front of described heat sink is provided with corresponding with the LED lamp array some annular seatings of fixed L ED lamp that are used for.
Further, described heat sink is the aluminium section bar heat sink.
By adopting the aforementioned techniques scheme, the beneficial effects of the utility model are: by heat sink directly is arranged between LED lamp array and the circuit board, but so that the utility model product quick heat radiating, prolonged the serviceable life of outdoor LED display screen, the utility model lamp drives unification, simple in structure, can extensively promote the use of.
Description of drawings
