The utility model relates to a kind of LED display, especially relates to a kind of totally-enclosed case of Surface Mount LED display.

Two, background technology:

In the background technology, along with the development of Surface Mount LED luminous tube technology, its brightness is greatly improved.Common direct insertion LED is little because of its volume ratio, be applied to the outdoor display screen closely watched just more and more, be mainly used in the high density display screen of 6mm-10mm spacing, because its pixel interval is less, picture element density in the unit are is higher, its picture exquisiteness is true to nature when closely watching, and good visual performance effect is arranged.Be applied in road, outdoor shopping centre just in large quantities and carry out ad distribution, business information issue and public good propaganda etc. on both sides of the road.Therefore this technology has boundless market prospects in this field.

The LED display of outdoor use must possess the function of waterproof, and this is the another one obstacle that Surface Mount LED luminous tube can't be used for outdoor LED display screen except that brightness problem.

Three, utility model content:

The utility model provides a kind of waterproof construction of Surface Mount LED display in order to solve the weak point in the above-mentioned background technology, and it is simple for structure, and Surface Mount LED luminous tube visual angle is bigger, and good water-proof effect has realized directly applying to Surface Mount LED luminous tube outdoor.

For achieving the above object, the technical solution adopted in the utility model is:

A kind of totally-enclosed case of Surface Mount LED display comprises the drain pan of display screen, and it is characterized in that: drive plate is arranged on the drain pan, and the case that is connected with drain pan is arranged on the drive plate front, and transparent front cover shell is arranged on the case front.

Above-mentioned case has the rectangular through-hole that is in array-like arrangement that is used to install the LED lamp, and the case inboard is provided with erection column, and case four limits are flange, and on the case and be distributed with bonding hole, four limits of case are provided with glue groove.

Above-mentioned transparent front cover shell is provided with the spheroidal projection, be provided with on the back side of transparent front cover shell with case on the corresponding bonding post in bonding hole, four limits of transparent front cover shell are provided with glue groove, transparent front cover shell and case are bonded as one.

The flange place of above-mentioned drain pan and case is provided with groove, and preceding sealing ring is housed in the groove, and the back sealing ring is equipped with in the junction of drain pan and display screen lamp box.

Above-mentioned drain pan four limits are flange, and the drain pan inboard is provided with the connection screw that studs with the copper mold insert.

Above-mentioned drive plate face bonding is connected to Surface Mount LED luminous tube, and the drive plate back side is welded with driving element and connector.

Compared with prior art, the advantage and the effect that the utlity model has are as follows:

The utility model connects the back with drain pan, case, PCB and front and back sealing rings by screw and forms display module, and this structure can realize Surface Mount LED luminous tube is directly applied to outdoor, has realized the application of outdoor Surface Mount LED display.In addition, design spheroidal projection makes Surface Mount LED luminous tube visual angle bigger in order to dodge Surface Mount LED luminous tube on the transparent front cover shell.
