Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the specific embodiments of the present invention and the accompanying drawings. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The technical solutions disclosed in the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

Referring to fig. 1 to 4, an embodiment of the invention discloses an illumination lamp, which includes a lamp body 100, a lamp panel 200, an antenna 300, and a radio frequency driving source 400.

The lamp body 100 is a basic component of the lighting fixture, and the lamp body 100 can provide a mounting base for other components of the lighting fixture. Specifically, the lamp body 100 includes a housing 110 and a mounting portion 120, the mounting portion 120 is disposed in the housing 110, and the mounting portion 120 and the housing 110 form a mounting space 130, and the housing 110 can shield components in the lighting fixture.

Generally, the mounting portion 120 can be disposed on the housing 110 by welding or screwing, but these two methods are inconvenient to detach and are not beneficial to maintaining and replacing components in the lighting fixture, so the mounting portion 120 can be disposed on the housing 110 by clamping, and when detaching, the mounting portion 120 and the housing 110 can be detached by applying a large detaching force manually, so that the mounting portion 120 and the housing 110 can be detached, and the detachment is completed, thereby the components in the lighting fixture can be maintained and replaced more conveniently. Specifically, a clamping groove can be formed in the inner side wall of the casing 110, a clamping strip can be arranged at the edge of the mounting portion 120, and the mounting portion 120 and the casing 110 can be connected in a clamping fit mode through the clamping groove and the clamping strip.

The lamp panel 200 is a component for installing the light source module and the control circuit in the lighting fixture, and the surface of the lamp panel 200 where the light source module is installed is the light emitting surface of the lamp panel 200. The internal surface relative with installation department 120 is the bottom surface in casing 110, because installation department 120 and casing 110 can form installation space 130, consequently, the distance between installation department 120 and the bottom surface is great, lamp plate 200 sets up in installation department 120, and deviate from the bottom surface of casing 110, avoid lamp plate 200 to set up the bottom surface at casing 110, because the distance is great between the bottom surface of installation department 120 and casing 110, consequently, the distance between lamp plate 200 and the casing 110 bottom surface is great, thereby make antenna 300 far away from the bottom surface of casing 110, and then make the radiation impedance between antenna 300 and the casing 110 great, avoid offering the perforation that is used for antenna 300 to radiate the electromagnetic wave on casing 110.

The lamp panel 200 may be connected to the mounting portion 120 by screws or may be connected to the mounting portion 120 by bonding. The light emitting surface of the lamp panel 200 deviates from the installation space 130, and the antenna 300 is disposed on the light emitting surface, so that the electromagnetic wave radiated by the antenna 300 can face the light emitting surface of the lighting fixture, and is radiated to the outside through the light emitting surface of the lighting fixture, thereby preventing the perforation for the antenna 300 to radiate the electromagnetic wave from being formed on the housing 110, and thus avoiding the problems of damaged appearance of the lighting fixture, reduced yield, increased cost, and the like.

The antenna 300 may be directly printed on the lamp panel 200 or may be welded on the lamp panel 200, which is not limited in the embodiment of the present invention. Radio frequency drive source 400 sets up in installation space 130, prevents to set up radio frequency drive source 400 at the light emitting area of lamp plate 200, leads to radio frequency drive source 400 to shelter from partial light to can avoid radio frequency drive source 400 to influence the light-emitting of illumination lamps and lanterns. The extending direction of antenna 300 is parallel to lamp plate 200, and is connected with radio frequency drive source 400 electricity, and the antenna 300 that is parallel to the setting of lamp plate 200 is protruding lower in the height of lamp plate 200 to can avoid antenna 300 to shelter from the light that lamp plate 200 sent.

In the lighting lamp disclosed by the embodiment of the invention, the antenna 300 is arranged on the light-emitting surface, the extending direction of the antenna 300 is parallel to the lamp panel 200, the radio frequency driving source 400 is arranged in the installation space 130 and is electrically connected with the antenna 300, the radio frequency driving source 400 is positioned on the back surface of the light-emitting surface, and the antenna 300 protrudes from the lamp panel 200 to a lower height, so that the radio frequency driving source 400 and the antenna 300 have less influence on light rays emitted by the lamp panel 200, the radio frequency driving source 400 and the antenna 300 are prevented from blocking the light rays emitted by the lamp panel 200, the radio frequency driving source 400 and the antenna 300 can be prevented from influencing the light emission of the lighting lamp, the light-emitting surface of the lighting lamp can not or less.

Meanwhile, the lamp panel 200 is disposed at the mounting portion 120, because the distance between the mounting portion 120 and the bottom surface of the housing 110 is relatively large, the distance between the lamp panel 200 and the bottom surface of the housing 110 is relatively large, so that the antenna 300 is relatively far from the bottom surface of the housing 110, and the radiation impedance between the antenna 300 and the housing 110 is relatively large, so that the loss of the housing 110 to the antenna 300 is relatively small, and further, the radiation efficiency and the gain of the antenna 300 are improved, and the antenna 300 is disposed at the lamp panel 200, so that the electromagnetic wave radiated by the antenna 300 can be radiated to the outside through the light emitting surface of the lighting fixture, and the perforation for the antenna 300 to radiate the electromagnetic wave is prevented from being formed on the housing 110, thereby preventing the appearance of the.

As can be seen, in the illumination lamp disclosed in the embodiment of the present invention, the antenna 300 is disposed in the illumination lamp to better radiate electromagnetic waves without damaging the housing 110 and affecting the light output of the illumination lamp.
