Description

Technical Field

[0001] This utility model relates to the field of lighting technology, specifically a lighting fixture structure with internal adjustable illumination range. Background Technology

[0002] Lighting fixtures are divided into many subcategories, but many lighting fixture designs require adjustment of the illumination angle. The methods for adjusting the illumination angle of lighting fixtures on the market use electric motors. Electric motors are convenient but unstable, and the heat emitted by the light source often damages components, affecting consumer use. Some manufacturers design mechanical structures to adjust the illumination angle, but this adjustment method is generally designed on the periphery of the lighting fixture. This peripheral design firstly affects the aesthetics of the lighting fixture, and secondly, this adjustment structure is not suitable when track lights need to be adjusted. The bottom of track lights is generally fixed inside the track, and the adjustment structure is located at the power supply and track position. When the lighting fixture needs to move inside the track, problems such as jamming often occur. Utility Model Content

[0003] The purpose of this utility model is to provide a lamp structure with internal adjustable illumination range, which can solve the problem of adjusting the illumination angle hidden inside the lamp, and the adjustment structure will not interfere with the installation of the guide rail lamp, and is applicable to different lamps.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A lighting fixture structure with adjustable illumination range includes a fixed base. The lower sides of the fixed base are designed with a rotating outer shell that engages with it. The rotating outer shell and the fixed base are connected by a laterally adjustable knob. A limiting boss is designed at the top of the fixed base. A rotating light source is designed in the middle of the fixed base and the rotating outer shell. A limiting platform is designed at the top of the rotating light source. External adjustment threads are designed on the lower perimeter of the rotating light source. Internal adjustment threads that mate with the external adjustment threads are designed on the inner wall of the rotating outer shell. A light-transmitting lens is designed at the end of the internal adjustment threads. A light source plate is fixed below the bottom of the rotating light source.

[0005] To further explain, the size of the limiting platform is larger than the limiting boss and the top position of the rotating shell.

[0006] According to the user manual of this utility model, when the user rotates the rotating housing, the inner and outer adjusting threads inside the housing drive the rotating light source to move towards the light-transmitting mirror. The limiting platform reaches the top of the rotating housing as the limit position, and the rotating light source moves to the limiting boss as the limit position when rotated in the opposite direction.

[0007] The advantages of this invention are that it can solve the problem of adjusting the illumination angle hidden inside the lamp, and it is applicable to different lamps. The internal structure of the lamp is simple, and the production cost is low and stable. Attached Figure Description

[0008] The above and / or additional aspects and advantages of this utility model will become apparent and readily understood from the description of the embodiments taken in conjunction with the following drawings, in which: Figure 1 A three-dimensional structural diagram of a lamp with internally adjustable illumination range; Figure 2 This is a schematic diagram showing the breakdown of a lamp structure that allows for internal adjustment of illumination range; Figure 3 A rotating state of a lamp structure for internally adjusting the illumination range. Figure 1 ; Figure 4 A rotating state of a lamp structure for internally adjusting the illumination range. Figure 2 ; Detailed Implementation The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0009] like Figure 1-4 As shown, a lamp structure with adjustable illumination range includes a fixed base 1. A rotating outer shell 2 is designed and engaged on both sides of the lower part of the fixed base 1. A lateral knob is designed between the rotating outer shell 2 and the fixed base 1 for mutual interlocking. A limiting boss 11 is designed at the top of the fixed base 1. A rotating light source 3 is designed in the middle of the fixed base 1 and the rotating outer shell 2. A limiting platform 31 is designed at the top of the rotating light source 3. External adjustment threads 32 are designed on the lower perimeter of the rotating light source 3. Internal adjustment threads 22 that mate with the external adjustment threads 32 are designed on the inner wall of the rotating outer shell 2. A light-transmitting lens 4 is designed at the end of the internal adjustment threads 22. A light source plate 33 is fixed below the bottom of the rotating light source 3.

[0010] To further explain, the size of the limiting platform 31 is larger than that of the limiting boss 11 and the top position of the rotating shell 2.

[0011] According to the instructions for use of this utility model, when the user rotates the rotating housing 2, the inner adjusting thread 22 and the outer adjusting thread 32 inside the housing drive the rotating light source 3 to move toward the light-transmitting mirror 4. The limiting platform 31 reaches the top of the rotating housing 2 as the limit position, and the rotating light source 3 moves in the opposite direction to the limiting boss 11 as the limit position.

[0012] The advantages of this utility model are that it can solve the problem of adjusting the illumination angle hidden inside the lamp, the adjustment structure will not interfere with the installation of the guide rail lamp, it is applicable to different lamps, the internal structure of the lamp is simple, the production cost is low and stable, etc.

[0013] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
