[0007] However, although the above patent can solve the deformation in the blow molding process, the problem that the lampshade is thick and can only emit light on one side still exists, which needs to be improved urgently. Utility Model Content

[0026] The following is an explanation and description of the technical scheme of the embodiment of the utility model in conjunction with the drawings of the embodiment of the utility model, but the following embodiment is only a preferred embodiment of the utility model, not all. Based on the embodiment in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the utility model.

[0027] A fully plasticized upper and lower luminous ultra-thin ceiling lamp according to an embodiment of the utility model will be described in detail below with reference to the accompanying drawings.

[0028] For easier understanding, see Figures 1 to 4 The utility model provides an embodiment of a fully plasticized upper and lower luminous ultra-thin ceiling lamp, comprising a mounting plate 1, a power cord 2 with a tail card to prevent pulling, an opal lampshade 3, an LED module device 4, a face ring 5, an optical light guide device 6 and a driving power supply device 7, wherein the mounting plate 1 is arranged at a groove portion at one end of the opal lampshade 3, the LED module device 4 is arranged on the inner wall of the opal lampshade 3, and the opal lampshade 3 is clamped in the face ring 5, the LED module device 4 comprises an LED and a PCB circuit board, and the LED is fixedly mounted on the PCB circuit board, the PCB circuit board is fixedly connected to the inner wall of the opal lampshade 3 in a ring shape, and an optical light guide device 6 is arranged between the opal lampshade 3 and the face ring 5;

[0029] The face ring 5, the mounting plate 1 and the LED module device 4 are all made by injection molding.

[0030] It should be noted that the LED module device 4 and the optical light guide device 6 form a side-emitting technology. The LED module device 4 is placed on the side of a 3mm thick dot light guide plate. The light emitted by the LED passes through the inside of the light guide plate and refracts dots of different sizes on the surface. A high-reflectivity reflective film is provided at the bottom of the light guide plate to reflect the light refracted by the light guide back again. Finally, the light coming out of the light guide plate is diffused for the second time through the diffuser plate to ensure that the light is uniform and not dazzling. At the same time, the face ring 5, the mounting plate 1 and the milky white lampshade 3 are all made by injection molding, and the full plasticization avoids the pollution to the environment caused by the traditional ceiling lamp powder spraying process.

[0031] In an optional embodiment: a clamping groove is provided in the groove portion of the milky white lampshade 3, and the mounting plate 1 is mounted on the milky white lampshade 3 and is clamped in the clamping groove by rotation.

[0032] It should be noted that, by utilizing the installed snap-fit ​​groove, the mounting plate 1 placed in the groove of the milky white lampshade 3 can be easily rotated and snap-fitted for positioning, thereby achieving installation and fixation between the milky white lampshade 3 and the mounting plate 1 .

[0033] In an optional embodiment: one end of the mounting plate 1 is fixedly connected to an electrically connected anti-pull power cord 2 with a tail clip.

[0034] It should be noted that the installed anti-pull power cord 2 with tail card can be powered by batteries or alternating current.

[0035] In an optional embodiment: the optical light guide device 6 includes a light guide plate, a diffuser plate and a reflective film, and the light guide plate, the diffuser plate and the reflective film are sequentially arranged on the inner wall of the face ring 5, the light guide plate is made of optical grade acrylic, and the reflective film is made of a PET substrate surface coating nano diffuse reflective composite optical material. The thickness of the light guide plate is set to 3mm, and the LED module device 4 is arranged on the side wall of the 3mm thick light guide plate with dots.

[0036] It should be noted that the light guide plate has a very high refractive index and does not absorb light. The light guide points are printed on the bottom of the optical grade acrylic sheet using laser engraving and UV screen printing technology, and then the optical grade acrylic sheet is used to absorb the light emitted from the lamp and stay on the surface of the optical grade acrylic sheet. When the light hits each light guide point, the reflected light will diffuse to various angles, and then destroy the reflection conditions and be emitted from the front of the light guide plate. Through various light guide points of different densities and sizes, the light guide plate can emit light evenly, and the uniformity can reach more than 90%;

[0037] The purpose of the reflective film is to reflect the light exposed from the bottom surface back to the light guide plate to improve the efficiency of light use; the reflective film uses a PET substrate surface coating nano diffuse reflection composite optical material, which has high luminous efficiency and low power consumption under the same area luminous brightness. Secondly, combined with the high haze and high light extraction efficiency of the PS diffuser, the effect of uniform light extraction is achieved.

[0038] In an optional embodiment: a driving power supply device 7 is fixedly installed inside the milky white lampshade 3 .

[0039] It should be noted that the installed driving power supply device 7 is used to convert the direct current of the battery into a stable voltage, and the driving power supply device 7 is generally a power driver.

[0040] Working principle: The mounting plate 1 is set in the groove at one end of the milky white lampshade 3, so that it can be clamped in the clamping groove by rotation, so that the milky white lampshade 3 and the mounting plate 1 are effectively installed and fixed. The LED module device 4 is set on the inner wall of the milky white lampshade 3, and is connected in series with the LED lamp beads through the PCB circuit board to form a current flow path, thereby realizing light emission. The face ring 5, the mounting plate 1 and the LED module device 4 are all injection molded, which makes the entire lamp structure more solid, and the materials made by the injection molding process can effectively avoid the pollution to the environment caused by the traditional ceiling lamp powder spraying process.

[0041] In addition, the utility model also uses side-lighting technology and optical light guide devices. The side-lighting technology places the LED module device 4 on the side of the 3mm thick dot light guide plate, allowing the light emitted by the LED to pass through the inside of the light guide plate and refract the dots of different sizes on the surface, thereby achieving a more uniform lighting effect. The optical light guide device ensures high uniformity and softness of the light output through the cooperation of the light guide plate, the diffuser plate and the reflective film.

[0042] As described above, the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
