Description

LED sign structure for easy maintenance {LED SIGN STRUCTURE FOR EASY ASSEMBLY AND MAINTENANCE}

The present invention relates to an LED sign structure that is easy to maintain.

Typically, a signboard is an advertisement that is installed on the exterior wall or pillar of a building, etc. by a store, company, or institution, displaying the company name, product name, business type, etc. in order to attract the attention of passers-by. It is tried in various forms and structures. It is one of the advertising methods available. In other words, it is most important for a signboard to clearly represent the business activities of the relevant entity while effectively attracting the attention of those around it.

As is well known, signs are mostly custom-made on-site and installed outdoors, except in special cases. In other words, signs are manufactured in various structures depending on the installation location and advertising content, so assembly is relatively difficult and costs increase, and if a breakdown or damage occurs, maintenance and repairs become quite difficult.

For example, an LED sign is largely divided into an LED module that emits light, and a power supply (SMPS) that supplies power to the LED module. Here, the lifespan of the power supply is shorter than that of the LED and the defect rate is high, so there is a problem in that the power supply must be repaired or replaced before the lifespan of the LED module ends. However, since the power supply for conventional signs is sealed inside the LED module, repair or replacement is inevitably complicated and difficult.

Therefore, when the power supply is broken or needs repair or replacement at the end of its life, there is a problem that the man-hours consumed for maintenance are wasted by replacing the entire LED module or disassembling the entire LED module. In particular, in the case of large signboards, the overall weight of the parts is large, so there is a significant waste of man-hours required in the power supply replacement process, so there is an urgent need to improve this.

The power supply insertion groove 313 may be formed as a groove with a shape corresponding to the size and shape of the power supply unit 22 so that the power supply unit 22 can be inserted.

However, although not shown in the drawing, there is a cable withdrawal groove at the bottom of the body 31 where the power supply insertion groove 313 is formed so that the cable 221 connected to the power supply unit 22 can be pulled out to the bottom of the body 31. can be formed. The cable withdrawal groove may be formed in a smaller size than the power unit insertion groove 313 so that only the cable 221 can be pulled out.

Additionally, connectors 23 may be installed on both ends of each cable 221. Connector 23 may be one of common wire connectors that can connect cables to each other.

The terminal connection hole 314 may be formed in the inner portion of the body 31 where the mounting groove 311 is formed. Specifically, the terminal connection hole 314 may be a hole formed in the front-back direction so that the power supply insertion groove 313 and the mounting groove 311 communicate with each other at the front part forming the mounting groove 311.

The power terminal 214 of the LED module 21 mounted in the mounting groove 311 is inserted to a predetermined depth into the power supply insertion groove 313 through the terminal connection hole 314, and the power supply unit is inserted into the power supply insertion groove. It may be contacted with the power supply terminal 222 of (22).

Specifically, in the LED module 21 mounted in the mounting groove 311, the power terminal 214 protruding from the rear of the LED module 21 may be inserted into the terminal connection hole 314. At this time, the power terminal 214 is in contact with the power supply terminal 222 of the power supply unit 22 inserted into the power unit insertion groove 313, and can receive power from the power supply terminal 222.

The elastic portion 32 may be installed to protrude forward from the inner surface of the body 31 where the mounting groove 311 is formed. As an example, the elastic portion 32 may be made of a spring.

The elastic portion 32 can be pushed to protrude a predetermined length in front of the LED module 21 seated in the mounting groove 311, so that the front end of the LED module 21 protrudes outward from the mounting groove 311. there is. Therefore, the light emitted from the LED 212 disposed on the front of the LED module 21 is not interfered with by the body 31 forming the mounting groove 311, and can be further spread outside the mounting groove 311. .

Both ends of the fixing part 33 are inserted into the slit groove 312 and can support the front of the LED module 21 mounted in the mounting groove 311. As an example, the fixing part 33 is formed in a 'ㄷ' shape, and both ends can be inserted into the slit groove 312.

A main body formed in a preset shape and including a frame with a groove-shaped internal space formed on the inside along the preset shape;
a lighting unit installed along a preset shape in the inner space of the frame to emit light; and
Characterized in that it includes a mounting part that is detachably formed on the main body and allows the lighting part to be installed in the main body when the lighting part is mounted,
The lighting unit,
LED module that emits light; and
It includes a power supply unit that supplies power to the LED module,
The mounting part,
It is formed in a larger size than the lighting unit and has a rectangular parallelepiped shape, with the front open on the inside so that the LED module can be mounted, and a mounting groove formed in the form of a groove of a predetermined depth is formed, and the upper and lower sides of the mounting groove are provided on both left and right sides. A slit groove is formed along the direction, and a power supply insertion groove into which the power supply unit can be inserted is formed at the rear of the mounting groove, and on the inside of the mounting groove, the power supply insertion groove and the mounting groove are connected in a forward and backward direction. A body in which a terminal connection hole is formed;
An elastic portion installed on the inner surface of the body where the mounting groove is formed to protrude forward;
A fixing part whose both ends are inserted into the slit groove to support the front of the LED module mounted in the mounting groove; and
It is installed on both ends of the body, and is formed in a gently curved shape, and includes wings capable of refracting the light emitted from the LED module forward,
The fixing part,
A pressure piece located in front of the mounting groove and supported in close contact with the front part of the LED module mounted in the mounting groove;
Tensile pieces extend rearward from both ends of the press piece and are formed by repeatedly folding a predetermined number of times in a zigzag shape;
It includes an insertion piece that extends rearward from the tension piece and is press-fitted into the slit groove to be inserted and fixed,
The LED module mounted in the mounting groove receives power when the power terminal protruding from the rear of the LED module is inserted into the terminal connection hole and comes into contact with the power supply terminal of the power supply unit inserted into the power unit insertion groove,
The LED module mounted in the mounting groove protrudes forward by a predetermined length by the elastic portion, so that the front of the LED module protrudes forward beyond the front of the mounting portion, and the front of the LED module is protruded forward by the fixing portion. An LED sign structure that is easy to maintain, characterized in that it is pressurized and supported rearward, and the tensile piece can be expanded by the length of the LED module protruding from the mounting groove.
delete delete In claim 1,
It further includes a fastening part that allows the body to be attached and detached to the frame,
The fastening part,
A ring portion fixed to the inner space of the frame; and
An LED sign structure that is easy to maintain, comprising a hook installed on the rear of the body and capable of supporting the hook by inserting it.
