Description
Technical field
The utility model belongs to LED field, particularly relates to a kind of LED display.
Background technology
The application of LED display is more and more extensive, it can be used on the various places such as outdoor advertising, physical culture, traffic, exhibition, rally, but these LED displays all need to be arranged on open air, it is directly exposed in sunlight, wind and rain, therefore LED display needs the intrusion that can prevent the foreign material such as rainwater, dust, avoid causing the faults such as LED display internal short circuits to occur; In addition, because LED display internal structure is limited, radiating effect is poor, if sealed tight, can cause luminescence component hydraulic performance decline in LED display time serious, and reduce service life.
Summary of the invention
The purpose of this utility model is to provide a kind of LED display, its long service life, perfect heat-dissipating for solving the deficiencies in the prior art.
The technical scheme in the invention for solving the technical problem is: a kind of LED display, comprise mounting casing and lampshade, two edges are vertically connected with in the edge of mounting casing, U-lag is provided with in edge, described lampshade is embedded between upper and lower edge two U-lag, circuit board and radiator fan that plurality of LEDs lamp pearl is installed is provided with between mounting casing and lampshade, be mounted with power supply and time switch in cavity between circuit board and radiator fan, described power supply is electrically connected with circuit board and radiator fan respectively; Described time switch is also connected with between power supply and radiator fan.
Preferably, described mounting casing and edge are structure as a whole.
The beneficial effects of the utility model are: LED display structure of the present utility model is simple, novel in design, is provided with radiator fan in described mounting casing, can dispel the heat, thoroughly meet cooling requirements to LED lamp bead, the service life of prolong display screen; The edge of band U-lag is adopted to be halved together between described mounting casing and lampshade, simple installation, rainproof, good dustproof effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.In figure:
1. mounting casing, 2. lampshade, 3.LED lamp pearl, 4. circuit board, 5. time switch, 6. radiator fan, 7. power supply, 8. edge, 9.U shape groove.
Detailed description of the invention
The technical solution of the utility model is further illustrated below by specific embodiment.
As shown in Figure 1: a kind of LED display, comprise mounting casing 1 and lampshade 2, be vertically connected with two edges 8 in the edge of mounting casing 1, in edge 8, be provided with U-lag 9, described lampshade 2 is embedded between upper and lower edge 8 liang of U-lags 9, and rainwater-proof, dust protection are effective; Avoid the inner intrusion because of rainwater or dust of display screen and the faults such as circuit for generating short circuit.
Circuit board 4 and radiator fan 6 that plurality of LEDs lamp pearl 3 is installed is provided with between mounting casing 1 and lampshade 2, be mounted with power supply 7 and time switch 5 in cavity between circuit board 4 and radiator fan 6, described power supply 7 is electrically connected with circuit board 4 and radiator fan 6 respectively; Described time switch 5 is also connected with between power supply 7 and radiator fan 6.
Described radiator fan 6 is connected with a time switch 5, starts radiator fan 6 timing thus and dispels the heat to circuit board 4 and LED lamp bead 3, thoroughly meet cooling requirements, the service life of prolong display screen.
LED display structure of the present utility model is simple, novel in design, radiator fan is provided with in described mounting casing 1, can dispel the heat to LED lamp bead 3, thoroughly meet cooling requirements, the edge 8 of band U-lag 9 is adopted to be halved together between described mounting casing 1 and lampshade 2, simple installation, rainproof, good dustproof effect.
Except technical characteristic described in description, be those skilled in the art known technology.
