Description

Technical Field

[0001] The utility model relates to a lighting and decorative lamp, in particular to a dual-light LED ceiling lamp. Background Art

[0002] With the development of science and technology, LED solid lighting sources are increasingly widely used, and more and more of them are used as lighting sources. Due to the flexible and diverse layout of LEDs, their applications in ambient lighting are also diverse. However, most current ambient lights are derived from the styles of traditional lamps, replacing traditional light sources such as incandescent lamps and energy-saving lamps with LED light sources. Therefore, most current ambient lights are still of traditional designs with a single style. Existing ceiling lamps are generally bulky, with numerous light-emitting units and complex structures. However, at one light-emitting unit, there is only one light-emitting mode, and the lighting effect is single. Summary of the Utility Model

[0004] The technical solution adopted by the utility model is as follows: The utility model includes a lamp tube, a suction top cover assembly, a power cord that also serves as a hanging wire, a COB LED module, an LED strip, an LED module fixing bracket, a floodlight diffuser, a spotlight lens, and a heat dissipation connecting piece. The upper and lower parts of the power cord pass through the suction top cover assembly and the lamp tube respectively and are fixedly connected. The heat dissipation connecting piece is arranged at the top of the inner cavity of the lamp tube and is fixedly connected in close contact. The COB LED module is fixedly connected to the bottom of the heat dissipation connecting piece through the LED module fixing bracket and is in close contact, so that the heat generated by the COB LED module is conducted to the lamp tube through the heat dissipation connecting piece for heat dissipation. The spotlight lens penetrates into the top neck of the floodlight diffuser from the bottom to clamp the floodlight diffuser and is connected and fixed to the LED module fixing bracket. The outer edge of the opening of the floodlight diffuser abuts against the outer edge of the bottom opening of the lamp tube. The spotlight lens is located in the light-emitting direction of the COB LED module to form a spotlight illumination light-emitting mode. The LED strip is fixedly connected in a ring on the inner wall of the lamp tube and surrounds the periphery of the floodlight diffuser. Through the light transmission of the floodlight diffuser, a floodlight illumination light-emitting mode is formed.

[0005] The dual-light LED ceiling lamp further includes a reflector which is fixed to the bottom of the heat dissipation connecting member. The reflector and the floodlight diffuser cover and a part of the inner wall of the lamp cylinder therebetween form a reflection cavity. The light emitted by the LED light strip, in addition to being directly transmitted through the floodlight diffuser cover, is also emitted outward through the floodlight diffuser cover after multiple refractions in the reflection cavity, forming a unique deep visual effect when viewed directly by the naked eye through the floodlight diffuser cover.

[0006] The reflector is made of nano-reflective paper.

[0007] The LED module fixing bracket is fixedly connected to the bottom of the heat dissipation connecting member through a plurality of screws, and at the same time, the COB LED module and the reflector are pressed and fixed.

[0008] The LED module fixing bracket is provided with a buckle notch, and the tail of the condenser lens is provided with a buckling portion. The condenser lens is buckled with the buckle notch through the buckling portion, so that the condenser lens is fixedly connected and fixed with the LED module fixing bracket.

[0009] The dual-light LED ceiling lamp further includes a power control module which is arranged in the heat dissipation connecting member. The power control module is connected to the power cord, and is electrically connected to the COB LED module and the LED light strip.

[0010] The heat dissipation connecting member is a profile with a concave shape on the side, and the power control module is adapted to the inner cavity size of the concave-shaped profile.

[0011] The dual-light LED ceiling lamp further includes a hollow external threaded tube. The power cord passes through the central hole of the hollow external threaded tube. The hollow external threaded tube respectively passes through the top of the lamp cylinder and the center of the heat dissipation connecting member, and the threads at its upper and lower ends are respectively connected through a wire clip nut and a threaded tube fixing nut, so that the power cord and the heat dissipation connecting member are respectively connected and fixed to the lamp cylinder.

[0012] Both the lamp cylinder and the heat dissipation connecting member are made of aluminum alloy material; the LED light strip is fixedly connected to the inner wall of the lamp cylinder by gluing or double-sided tape.

[0013] The floodlight diffuser cover is made of glass or plastic and has a frustum of a cone shape or a frustum of a pyramid shape.

The condenser lens penetrates into the top neck of the floodlight diffuser from the bottom to clamp the floodlight diffuser and is connected and fixed to the LED module fixing bracket. The outer edge of the opening of the floodlight diffuser abuts against the outer edge of the bottom opening of the lamp barrel. The condenser lens is located in the light-emitting direction of the COB LED module to form a light-emitting mode of concentrated light illumination. The LED light strip is fixedly connected in a ring shape to the inner wall of the lamp barrel and surrounds the periphery of the floodlight diffuser. Through the light transmission of the floodlight diffuser, a light-emitting mode of floodlight illumination is formed. The present utility model overcomes the defects and deficiencies of the prior art. Through a highly integrated internal structure design and a simple external shape design, the main body of the lamp has only the shape of a lamp barrel. Compared with the existing chandeliers with complex structures and shapes, its design is extremely simplified, does not occupy space, and has a unique external shape effect. At the same time, through the COB LED module, a light-emitting mode of concentrated light illumination is formed through the condenser lens, and through the LED light strip in a ring shape, a light-emitting mode of floodlight illumination is formed through the light transmission of the floodlight diffuser. Two light-emitting modes of concentrated light and floodlight are integrated. Through circuit control, three light-emitting effects of single concentrated light, single floodlight, and concentrated light + floodlight can be achieved, making the chandelier no longer monotonous and having a unique light-emitting effect. Therefore, the present utility model is a dual-light LED chandelier with a clever structure, a beautiful and simple external shape, and integrating two light-emitting modes of concentrated light and floodlight.
