›DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT · 1 of 2

In order to make the purposes, technical solutions, and advantages of the present application clearer, the present application will be further described in detail hereinafter with reference to accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely intended to explain but not to limit the present application.

It is to be noted that when referred to as being “fixed to” or “arranged in” another element, an element may be located directly on the another element, or a third element exists therebetween. When referred to as being “connected to” another element, an element may be directly connected to the another element, or a third element exists therebetween.

It is also to be noted that locality terms such as left, right, upper and lower in the embodiment are relative concepts, or referenced against normal operation state of a product, which should not be deemed limitative.

FIGS. 1 to 4 are respective schematic views of an ultrathin lamp provided by an embodiment of the present application; the ultrathin lamp includes a mounting base 1 , a light source plate 2 embedded at the bottom of the mounting base 1 , a lens 3 provided below the light source plate 2 and a diffusion cover 4 provided below the lens 3 . Furthermore, the bottom of the mounting base 1 has a recess 11 in which the light source plate 2 , the lens 3 and the diffusion cover 4 are embedded; a support table 12 including a bottom plate 121 and a curved portion 122 projecting on the bottom plate 121 is provided around the recess 11 . The ratio of the width L of the support table 12 to the thickness H 2 of the thickest portion of the support table 12 is 5.5 to 10. Therefore, overall thickness of the lamp is relatively thin, and thus meets the lighting requirement, at the same time, can fully meet the need for decoration on the market.

The ultrathin lamp provided by the present application is configured such that the support table 12 is provided on the mounting base 1 and the ratio of the width L of the support table 12 to the thickness H 2 of the thickest portion of the support table 12 is set to 5.5 to 10, such that under the conditions of satisfying technological feasibility of the support base 12 , the whole thickness of the support table 12 and the is lamp can be relatively thin, so that the overall appearance is more decorative and thus satisfying the ultrathin requirements on the market.

Preferably, the support table 12 may be made of plastic material or metallic material, and when the support table 12 is made of plastic material, the appearance of the support table 12 is beautiful, and since the plastic has a certain malleability, the situation which the support table 12 is under force and easy to has an irregular external surface which makes the appearance not good can be avoided; when the support table 12 is made of metal material, heat dissipation of the support table 12 is better, which can help extend service life of the lamp.

As a specific embodiment, the ratio of the width L of the support table 12 to the thickness H 3 of the thickest portion of the curved portion 122 is 4 to 10, and the thickest portion of the curved portion 122 is an inner contour line of the support table 12 , which means the ratio of the width L of the support table 12 to the thickness of the inner contour line of the support table 12 is 4 to 10, therefore, the thickness of the support table 12 can be made thin so that the weight of the whole mounting base 1 is also lighter.

As a specific embodiment, the curved portion 122 includes a base portion 1221 having a circular fillet and an arc portion 1222 extending over the base portion 1221 . The base portion 1221 having the circular fillet is provided such that the transition between the bottom plate 121 of the support table 12 and the arc portion 1222 is more smooth and softer, so as to enhance sense of beauty of the appearance.

As a specific embodiment, the ratio of the width L of the support table 12 to the sum of the thickness H 1 of the bottom plate 121 and the base portion 1221 of the support table 12 is 3.5 to 10. In this way, the thickness of the support table 12 can be further restricted.

As a preferred embodiment, the ratio of the thickness H 2 of the support table 12 to the sum of the thickness H 1 of the bottom plate 121 and the base portion 1221 of the support table 12 is 1 to 3. In this way, the thickness of the support table 12 can be further controlled within a thinner range so as to meet the market requirements.

As a specific embodiment, the curvature of the arc portion 1222 of the curved portion 122 is different from the curvature of the diffusion cover 4 , so that the support table 12 and the diffusion cover 4 can be independent of each other and the overall thickness of the support table 12 can be made thinner; the diffusion cover 4 can be further set according to requirements for light diffusion, so as to meet design requirements.

As a specific embodiment, the support table 12 may be of circular or regular polygonal, for example, a regular quadrilateral, a regular hexagon, etc., and may be appropriately adjusted according to the customer's needs, which should not be limited herein.

As a specific embodiment, the diffusion cover 4 may also be of circular or regular polygonal. Preferably, the shape of the support table 12 is identical with the shape of the diffusion cover 4 .

As a specific embodiment, the recess 11 at the bottom of the mounting base 1 includes a first recess 111 recessed at the bottom of the mounting base 1 and a second recess 112 recessed in the first recess 111 , which means the recess 11 at the bottom of the mounting base 1 is a stepped recess in which both the light source plate 2 and the lens 3 are embedded in the second recess 112 and the diffusion cover 4 is embedded in the first recess 111 . In this way, not only the overall thickness of the mounting base 1 and the support table 12 can be made relatively thin, but also the light diffusion effect of the diffusion cover 4 can be satisfied.
