Embodiment 1

[0022] A kind of ultra-thin LED ceiling lamp proposed in this embodiment, such as figure 1 , figure 2 and image 3 As shown, it includes a chassis 1, an LED light source board 2, a driver 3, a curved light guide plate 4 and a curved lampshade 5, and the structure of the lampshade 5 is the same as that of the light guide plate 4, and the LED light source board 2 wraps around the light guide plate 4 The side surface of the light guide plate 4 is closely connected with the side surface of the light guide plate 4. The upper curved surface 41 of the light guide plate 4 is the light-emitting surface, and the upper curved surface 41 of the light guide plate 4 is closely connected with the lower curved surface 52 of the lampshade 5. The light guide plate 4 will be located on its side. The light emitted by the light source board 2 is guided to the light emitting direction of the lampshade 5, the edge of the lampshade 5 is connected with the edge of the chassis 1 through the decorativ...

Embodiment 2

[0028] The structure of an ultra-thin LED ceiling lamp proposed in this embodiment is as follows: Figure 4 As shown, it defines the structure of the curved light guide plate in the ultra-thin LED ceiling lamp proposed in Embodiment 1, that is, the middle part of the light guide plate 4 is a circular convex curved body 43 that protrudes upward, and the transition of the light guide plate 4 Part of it is a ring-shaped downward convex concave surface body 44, the outer part of the light guide plate 4 is a ring-shaped planar body 45, the middle part of the light guide plate 4 smoothly transitions to the transition part of the light guide plate 4, and the transition of the light guide plate 4 Part of the transition to the outer part of the light guide plate 4 is smooth, and multiple LED lamp beads 22 are in close contact with the side of the outer part of the light guide plate 4; the light guide plate 4 with this structure is not only beautiful, but also can make the light output m...

Embodiment 3

[0031] The structure of an ultra-thin LED ceiling lamp proposed in this embodiment is as follows: Figure 5 As shown, it defines the structure of the chassis in the ultra-thin LED ceiling lamp proposed in Embodiment 1 or Embodiment 2, that is, the chassis 1 is composed of a circular main body 11 and an annular stepped part 12 integrally provided with the circular main body 11 The outer end of the step part 12 is integrally connected with a ring-shaped limiting plate 13, the LED light source board 2 is limited between the ring-shaped limiting plate 13 and the side of the light guide plate 4, and one end of the decorative ring 6 is located in the step part 12; set The step part 12 is to make the lower end part of the decorative ring 6 just stuck in the step part 12, so that the lower end part of the decorative ring 6 is flush with the circular main body 11 or lower than the circular main body 11, so that the whole is more beautiful, and also makes the Ultra-thin LED ceiling ligh...

Abstract

The invention discloses an ultrathin LED ceiling lamp. The ultrathin LED ceiling lamp comprises a chassis, an LED light source plate, a drive, a light guide plate shaped as a curved surface, and a lamp cover shaped as a curve surface; the side surface, surrounding the light guide plate, of the LED light source plate is tightly bonded and connected with the side surface of the light guide plate; an upper curved surface of the light guide plate is a light outlet surface, and is tightly bonded and connected with a lower curved surface of the lamp cover; the edge of the lamp cover and the edge of the chassis are connected through a decoration ring; and the drive is mounted on the chassis, and is positioned in a cavity surrounded by the chassis and the light guide plate. The ultrathin LED ceiling lamp has the following advantages: the light guide plate shaped as the curved surface is adopted to enable the LED ceiling lamp to continue the characteristics of a traditional LED ceiling lamp; the drive is mounted in the lamp; the side surface, surrounding the light guide plate, of the LED light source plate is tightly bonded and connected with the side surface of the light guide plate, and the side surface is used for incidence, so that the LED ceiling lamp has the side light emitting characteristic, and the thickness of the whole lamp can be ultrathin; and the lamp cover shaped as the curved surface is adopted, and the upper curved surface of the light guide plate and the lower curved surface of the lamp cover are tightly bonded and connected, so that the outlet light is more uniform and milder.

Description

technical field [0001] The invention relates to a lighting device, in particular to an ultra-thin LED ceiling lamp. Background technique [0002] With the continuous development of the LED industry, technological leaps and breakthroughs, and the vigorous promotion of applications, the luminous efficiency of LEDs is also constantly improving, and the price is constantly falling. There are more and more LED application products. Especially for LED lighting fixtures for general lighting, its application prospect is even wider. As a commonly used lighting product, LED ceiling lamps are deeply accepted by the market. Most of the current LED ceiling lamps are of the direct type. Due to consideration of the uniformity of the light spot and the influence of the driver on the LED light output, the thickness of this LED ceiling lamp is generally thicker. In order to solve the problem of the thickness of the existing LED ceiling lamps, a side-emitting flat panel light using a light ...
