[0021] like Figures 1 to 6As shown, this embodiment provides a downlight that is easy to assemble, including at least two downlight bodies. Each downlight body includes a front cover assembly 1 and a heat sink assembly 2. The heat sink assembly 2 has a first recess 201, and an LED light source assembly 3 is disposed within the first recess 201. The heat sink assembly 2 is mainly used to house the LED light source assembly 3 and absorb heat from the LED light source assembly 3 to achieve a heat dissipation effect. The front cover assembly 1 is mounted on the heat sink assembly 2 and is mainly fixed to the ceiling. A mounting platform 11 is provided at the edge of the front cover assembly 1. When the two front cover assemblies 1 are attached, they are generally arranged horizontally. The mounting platform 11 is connected to the mounting platform 11 of another front cover assembly 1 by a connecting part 4. The connecting part 4 is fixed to the mounting platform 11 by screws. The mounting platform 11 is flat. The screws pass through the connecting part 4 and enter the mounting platform, which can play a fixing role and prevent the two downlights from separating. The preferred method is to use two connecting parts 4 to fix them on both sides, so that there will be no loosening. By connecting the downlight bodies through the connecting parts 4, multiple sets of downlights can be arranged. Users can assemble different shapes according to the arrangement. The installation is convenient. Enterprises only need to produce one type of downlight, which reduces the production and inventory costs. Replacement is convenient after damage.

[0022] As an optional embodiment, the mounting platform 11 is recessed downwards to form a first limiting edge 12 on the outer side. In order to achieve a more secure effect, the connecting part 4 is mounted on the mounting platform 11, and the end side of the connecting part 4 can be constrained by the first limiting edge 12 to achieve a tighter effect. In addition, a limiting block 41 is provided in the middle of the connecting part 4, which is also to allow the limiting block 41 to constrain the side wall of the front cover assembly 1.

[0023] As an optional embodiment, the front cover assembly 1 includes an outer cover 13 and a lamp cup 14. The outer cover 13 has a first through hole 131 in the middle, and the lamp cup 14 has a second through hole 141 in the middle. The lamp cup 14 is installed in the first through hole 131. The main function of the outer cover 13 is to be fixedly connected to the ceiling. The function of the lamp cup 14 is to be hinged to the heat sink assembly 2. Moreover, the interior of the lamp cup 14 can reflect light during the illumination of the LED light source.

[0024] As an optional embodiment, the front of the outer cover 13 has a square structure, and the mounting platform 11 is located at the four corners of the outer cover 13, so that the connecting part 4 can be used to connect two downlights regardless of whether they are on the left or right sides or the front or back sides.

[0025] As an optional embodiment, hinge posts 21 extend from both ends of the front side of the heat sink assembly 2. The front end of the hinge post 21 is hinged to the lamp cup 14. A ball bearing 22 is installed at the upper end of the hinge post 21. Several third through holes 142 are provided at the contact position between the ball bearing 22 and the lamp cup 14. The ball bearing 22 is fixed by being inserted into the third through holes 142. The front cover assembly 1 and the heat sink assembly 2 can be directly hinged and rotated. The angle is fixed by the ball bearing 22 to avoid loosening.

[0026] As an optional embodiment, the outer cover 13 and the lamp cup 14 are connected by several snap-fit ​​fasteners 143. In order to replace the lamp cup module, the lamp cup can be conical or square-pyramidal, and there will also be different power. Therefore, the outer cover 13 can replace the lamp cup module uniformly. The connection by snap-fit ​​fasteners 143 is more convenient. A spring piece 133 is provided on the outer side of the outer cover 13. The spring piece 133 is used to support and fix the downlight to the ceiling.

[0027] As an optional embodiment, a second limiting edge 144 is provided around the front opening of the lamp cup 14, and a step 134 corresponding to the second limiting edge 144 is provided at the inner edge of the outer cover 13. The first limiting edge 12 contacts the step 134 to prevent the lamp cup 14 from falling off. The lamp cup 14 will enter the first limiting edge 12 from the front of the outer cover 13 and contact the step 134, and then be fastened. This makes the installation more stable and less prone to loosening.

[0028] As an optional embodiment, the LED light source assembly 3 includes an LED lamp 31 and a lens 32. The LED lamp 31 is located at the bottom of the first recess 201, and the lens 32 is mounted on the LED lamp 31. The LED lamp 31 is used to emit light, which is then refracted by the lens 32, resulting in a better lighting effect.

[0029] As an optional embodiment, the heat sink assembly 2 includes a heat sink body 23 and a hinge cup 24. Since it is difficult to die-cast the heat sink body 23 and the hinge cup 24 as a whole, they need to be produced as two parts. The hinge cup 24 is fixedly connected to the heat sink body 23. Screws are inserted into the heat sink body 23 at the rear side of the heat sink body 23 to connect with the hinge cup 24. The LED light source assembly 3 is fixed by the hinge cup 24. The LED light source assembly 3 is placed inside the heat sink body 23. After the screws are tightened, the hinge cup 24 presses down and fixes the LED light source assembly 3. The hinge posts 21 are located on both sides of the hinge cup 24. The hinge posts 21 and the hinge cup 24 are integrally formed.

[0030] In existing technology, factories need to produce two, three, or four sets of downlights according to user requirements, including an outer frame. Two, three, or four downlights are then fixed within frames of different sizes, and the entire unit is shipped as a single model. For enterprises, different specifications require more production and inventory, significantly increasing costs. Furthermore, if one set is damaged during use, the entire unit needs to be replaced, resulting in resource waste. Therefore, this invention provides a downlight that is easy to assemble. A mounting platform 11 is provided on the edge of the front cover assembly 1. Connecting parts 4 are installed on the mounting platforms 11 of the first and second front cover assemblies 1 for connection. The connecting parts 4 are fixed to the mounting platforms 11 with screws, allowing for multiple sets of downlights to be arranged. Users can assemble different shapes according to the arrangement, making installation convenient. Enterprises only need to produce one type of downlight, reducing production and inventory costs. Replacement is also convenient after damage. The above embodiments are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited thereto. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model are equivalent substitutions and are included within the protection scope of the present utility model.
