1. Field of the Invention
The present invention relates to an LED light module, especially to an LED light module wherein any individual LED light of the LED light module can be easily disassembled.
2. Description of the Prior Arts
Light Emitting Diode (LED) is a semiconductor light source. LED has many advantages such as high efficiency, long life span, durability against breaking, quickness in reaction and high reliability, and the LED light has replaced the conventional light gradually.
The LED light has a variety of utilities, one of which is for use in the advertisement billboard. When used in a billboard, multiple LEDs with a mounting board constitute an LED light module. The LED lights are mounted on the mounting board and are arranged in order to form an illustration or a character. Because the illustration or character comprises LED lights, even if only one LED light is damaged, the broken LED light would cause a serious impact on the whole illustration or character. As a result, the broken LED light has to be repaired or replaced as soon as possible.
However, the LED light cannot be separated from the mounted board easily in the conventional LED light module, so the user needs to remove the whole LED light module even only one LED light is damaged, and it causes great inconvenience, especially because the billboard is often mounted on a high place. The operation and transportation of the LED light module is more inconvenient
To overcome the shortcomings, the present invention provides an LED light module to mitigate or obviate the aforementioned problems.
The main objective of the present invention is to provide an LED light module wherein any individual LED light of the LED light module can be easily disassembled.
The LED light module in accordance with the present invention has a mounting board and multiple LED lights mounted securely on the mounting board. Each LED light has a casing, a lighting module and two resilient sheets. The lighting module is mounted in the casing. The resilient sheets are mounted on an outside wall of the casing and abut an annular edge around a mounting hole of the mounting board. The LED lights are mounted securely on the mounting board by the resilient three of the resilient sheets, so the user only has to push the LED light to resist the slightly resilient force, and the LED light can be disassembled from the mounting board. Thus, any individual LED light can be easily disassembled.
Other objectives, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

The casing is mounted in one of the mounting holes 11 of the mounting board 10, and has a back cover 30, a front cover 40 and an inner cavity. The back cover 30 has two back buckling segments 32 and a power hole 33. In a preferred embodiment, the back cover 30 has an inner cavity, a front side opening and an annular flange 31 formed annularly around an outside wall of the back cover 30. The back buckling segments 32 are formed on the annular flange 31, and each back buckling segment 32 has a buckling hole 321 and two separating recesses 322. The separating recesses 322 are respectively formed in two opposite sides of the back buckling segment 32. The back cover 30 has two buckles 34 formed oppositely on an annular edge around the power hole 33 of the back cover 30.
The front cover 40 has a lens segment 42 and two front buckling segments 43. The lens segment 42 is transparent and is formed on a front side of the front cover 40. The front buckling segments 43 respectively engage with the back buckling segments 32. In a preferred embodiment, a backside of each front buckling segment 43 is a slope. A diameter of the lens segment 42 is bigger than a diameter of the mounting hole 11 of the mounting board 10. The lens segment 42 has two slope recesses 421 formed in a periphery of the lens segment 42. The front cover 40 covers the opening of the back cover 30, and has a surrounding wall 41. The surrounding wall 41 is mounted in the mounting hole 11 of the mounting board 10, has an inner cavity and two side openings, and is mounted around the back cover 30. The front cover 40 further has two connecting segments 44 formed on an outside wall of the surrounding wall 41, and each connecting segment 44 has a front protrusion 441 and a back protrusion 442. The front side of the back protrusion 442 is a slope.
The inner cavity of the casing is formed between the front cover 40 and the back cover 30.
The lighting module 50 is mounted in the inner cavity of the casing, and has a circuit board 51 and at least one LED 52 mounted on the circuit board 51. In a preferred embodiment, the lighting module 50 has multiple LEDs 52, and the LEDs 52 have at least two different colors. The lighting module 50 has multiple pins 511 and a pin gasket 53. The pins 511 are formed on a backside of the circuit board 51. The pin gasket 53 is mounted on the backside of the circuit board 51, and is mounted around the pins 511.
The refraction lens 61 is mounted in the inner cavity of the casing, and is mounted between the lens segment 42 of the front cover 40 and the lighting module 50.
The waterproof gasket 62 is mounted on the casing, and is mounted between the front cover 40 and the back cover 30. In a preferred embodiment, the waterproof gasket 62 is mounted around the back cover 30, and is clamped between the annular flange 31 of the back cover 30 and the surrounding wall 41 of the front cover 40.

A conventional billboard tends to be huge, so the billboard is often mounted on the top of a building. Besides, the billboard is often mounted on a periphery of the top floor, so the building would not block the billboard. The billboard is installed in two ways:
First, a stationary maintenance route is mounted behind the billboard, so the maintenance route would not block the billboard.
Second, a removable maintenance route is mounted in front of the billboard, but is installed only when the billboard needs maintenance work.
The present invention applies to the above two ways, and the LED lights 20 can be disassembled in two directions.
One disassembling direction is to disassemble the LED lights from the back of the mounting board 10. With reference to
Another disassembling direction is to disassemble the LED lights from the front of the mounting board 10. With reference to
