A kind of simple downlight, comprising: the upper end of cylinder, both ends open, cylinder is equipped with radiator；Shell, setting exist The outside of cylinder, the lower end of shell are provided with the face ring positioned at its periphery；It is characterized in that, lantern ring, setting on the shell, is located at The top of the face ring, elastic slice of the lantern ring integrally formed with multiple circle distributions thereon.

It is provided with several hollow-out parts being connected to inner barrel on the radiator, is provided with hair on the lower end surface of radiator Optical assembly, the inner wall of radiator offer the positioning groove passed through for the power supply line being connected with luminescence component, the radiator Upper end is removably connected with tension disc, has between tension disc and hollow-out parts and makes way for the gap that power supply line passes through.

The top of the radiator offers a counterbore, which is equipped with internal screw thread, and the tension disc is equipped with and this The threaded post that internal screw thread matches.

The top of the cylinder and the lower thread of radiator connect, and the luminescence component is located at inner barrel, cylinder Lower part is provided with light-transmitting plate, which does not stretch out in the lower end surface of shell.

In one embodiment of the utility model, the first external screw thread is provided in the peripheral surface of the radiator, The inner surface of the shell is equipped with the first internal screw thread to match with the first external screw thread.

In second embodiment of the utility model, cylinder and shell are crossed by one between the shell and cylinder Drive-connecting shaft rotation connection.

Preferably, the lantern ring and elastic slice thereon are made of PC material.

The shell is substantially cylindrical in shape, and the circumferential surface of shell is inwardly formed a ring annular groove, the upper end of the face ring With annular flange, the locating slot for accommodating the lantern ring is constituted between the annular groove and annular flange.

The beneficial effects of the utility model are: the downlight of the above structure has setting on the shell and is located above face ring Lantern ring, integrally formed multiple elastic slices substitute traditional spring clip thereon for utilization, so that the structure of downlight is eased, production dress With convenience, cost is cheaper.

Detailed description of the invention

The utility model is described in further detail with reference to the accompanying drawings and detailed description.

Fig. 1 is the structural schematic diagram of one embodiment of the utility model；

Fig. 2 is the structural decomposition diagram of Fig. 1；

Fig. 3 is the structural schematic diagram of another embodiment of the utility model；

Fig. 4 is the structural decomposition diagram of Fig. 3.

Specific embodiment

Referring to figs. 1 to Fig. 4, a kind of simple downlight, comprising: cylinder 1, both ends open, the upper end of cylinder 1 are equipped with heat dissipation Device 2；Shell 3, is arranged in the outside of cylinder 1, and the lower end of shell 3 is provided with the face ring 4 positioned at its periphery；Lantern ring 5, setting is outside On shell 3, positioned at the top of the face ring 4, elastic slice 51 of the lantern ring 5 integrally formed with multiple circle distributions thereon.The above structure Downlight there is the lantern ring 5 for being arranged on shell 3 and being located at 4 top of face ring, integrally formed multiple elastic slices 51 replace thereon for utilization For traditional spring clip, so that the structure of downlight is eased, production assembly convenience, it is preferable that the lantern ring 5 and bullet thereon Piece 51 is made of PC material, further decreases the cost of product.

It is provided with several with hollow-out parts that are being connected to inside cylinder 1 on the radiator 2, is arranged on the lower end surface of radiator 2 There is luminescence component (not shown), the inner wall of radiator 2 offers the positioning passed through for the power supply line being connected with luminescence component Groove 21, the upper end of the radiator 2 are removably connected with tension disc 6, have between tension disc 6 and hollow-out parts and make way for power supply The gap that line passes through.

The top of the radiator 2 offers a counterbore 22, which is equipped with internal screw thread, sets on the tension disc 6 There is the threaded post to match with the internal screw thread.

The top of the cylinder 1 is connect with the lower thread of radiator 2, and the luminescence component is located inside cylinder 1, cylinder 1 lower part is provided with light-transmitting plate, which does not stretch out in the lower end surface of shell 3, to prevent downlight from generating dazzle.
