[0002] Light-emitting diodes are semiconductor electronic components that can convert electrical energy into light energy. This electronic component appeared as early as 1962. In the early days, it could only emit low-intensity red light. Later, other monochromatic versions were developed. Today, the light it can emit covers visible light, infrared light, and ultraviolet light, and the luminosity has also increased to a considerable level. Initially, it was used in indicator lights, display boards, etc.; with the continuous advancement of technology, light-emitting diodes have been widely used in monitors, televisions, lighting decorations, and plant growth lamps.

[0003] Existing LED lamps usually use a combination of multiple LED lamp beads on an LED light strip for lighting.

[0036] DETAILED DESCRIPTION

[0037] The present invention is described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the present invention, but are not intended to limit the present invention in any form. It should be noted that, for those of ordinary skill in the art, several variations and improvements may be made without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0038] In the description of the present invention, it should be understood that the terms "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0039] like Figure 1 As shown, the LED light strip provided by the present invention comprises a widthwise extending portion 110, wherein two end surfaces of the widthwise extending portion 110 along the thickness extending direction respectively form a first end surface 111 and a second end surface 112; a fin structure 120 is provided on the first end surface 111, and the fin structure 120 is integrally formed or fastened to the widthwise extending portion 110; a plurality of fin structures 120 are arranged along the width extending direction of the widthwise extending portion 110; and the plurality of fin structures 120 at least include Two mounting fins 121, and the space between two adjacent mounting fins 121 constitute a first mounting space 131; a mounting groove is provided on the second end surface 112, and limiting protrusions 140 are provided at both ends of the mounting groove, respectively, and a second mounting space 132 is formed between the two limiting protrusions 140; fixing protrusions 150 are provided at both ends of the width extension direction of the width extension portion 110, and the fixing protrusions 150 are raised relative to the first end surface 111 and / or the second end surface 112. In a preferred example, the height of the two limiting protrusions 140 exceeds the height of the LED lamp beads installed in the second mounting space 132, which, on the one hand, protects the LED lamp beads during transportation and installation, and on the other hand, effectively reduces light loss.

[0040] The plurality of fin structures 120 also include heat dissipation fins 122, which are arranged on the two sides of the mounting fins 121 along the width direction, on the other side of the side opposite to the first mounting space 131. The mounting fins 121 include a raised portion 125 and a ridge portion 126. Along the cross section of the LED light strip 1, the ridge portion 126 is arranged perpendicular to the first end surface 111, and the raised portion 125 is installed on the ridge portion 126 and extends to the first mounting space 131. It should be noted that the mounting fins 122 can not only form a mounting limit for the structure in the first mounting space, but also play a role in heat dissipation. The overall cross-section of the mounting fin 122 is T-shaped, and the setting of the ridge portion 126 can play a role in limiting and fixing the hook 4 installed in the first mounting space 131. In a preferred example, one end of the hook 4 has a protruding ear, and a mounting hole is provided on the ear. The ear is matched and inserted in the first mounting space 131 and can slide freely along the length direction of the LED light strip 1, and a flat head bolt can be installed on the mounting hole for fixing. The other end of the hook 4 is also fixed by a bolt, so that the entire LED light strip 1 is fixed as a whole through the hook 4.

[0041] The setting of the fin structure 120, on the one hand, can improve the heat dissipation efficiency of the LED lamp beads installed thereon, and on the other hand, can also improve the overall strength of the LED light strip, prevent bending or twisting, and play the role of a reinforcing rib. Considering that the closer the position to the LED lamp is to the heat conduction path of the LED lamp beads, the higher the temperature is. Therefore, preferably, the height of the fin structure 120 decreases successively from the center position to the two end positions in the width extension direction of the width extension portion 110. In other words, at a position with high temperature, in order to meet the heat dissipation needs, the heat dissipation surface area of ​​the fin structure 120 is also set larger accordingly. Further preferably, the fin structure 120 is arranged axially symmetrically in the width extension direction of the width extension portion 110, which can enhance the overall aesthetics, optimize the heat dissipation path, and improve the heat dissipation efficiency. Preferably, the center position can be the center position in a geometric sense, or it can refer to the position where the LED lamp bead generates the most heat.

[0042] Preferably, the fixing protrusion 150 is raised relative to the second end face 112, and an anti-skid protrusion 151 is provided on the relatively outer end face of the fixing protrusion 150 in the width extension direction. The anti-skid protrusion 151 can make the overall appearance of the LED light bar more beautiful, and can also play a role in preventing slipping when grasped by hand. Preferably, the LED light bar is an aluminum alloy profile LED light bar, which is more convenient to process. The above-mentioned LED light bar does not need to use other auxiliary heat dissipation. The structural characteristics of the self-heating can ensure that the temperature of the LED lamp is about 50°C, thereby extending the service life of the LED lamp.

[0043] like Figure 2As shown, the present invention further provides a lamp, comprising the above-mentioned LED light strip 1, wherein the first mounting space 131 forms an installation space for the hook 4, and the second mounting space 132 forms an installation space for the PCB board 8. The LED lamp is preferably an LED lamp bead. Preferably, the PCB board 8 is glued to the LED light strip 1 by a heat-conductive double-sided adhesive 11, and a label 10 is attached to the PCB board 8.

[0044] Furthermore, the single-board design of the PCB allows the PCB to be used as part of the external structure of the light strip. The PCB board 8 is provided with a power supply line 9, which passes through a wire clip 6 provided on the LED light strip 1 and is connected to the PCB board 8. The provision of the wire clip 6 enables the power supply line 9 to withstand a certain tension, reduces the difficulty of installation, and provides overall structural stability. The two ends of the LED light strip 1 along the length extension direction are respectively fastened with a first protective cover 2 and a second protective cover 3, as shown in FIG. Figure 3 , Figure 4 As shown, the protective cover is mounted on the LED light strip 1 by means of the first screw 5; the first mounting space 131 above the first protective cover 2 and the second protective cover 3 is fastened with a hook 4 by means of the second screw 7; the arrangement of the first protective cover 2 and the second protective cover 3 can effectively protect the cross section of the LED light strip 1 to prevent bending, twisting or bending. The first protective cover 2 includes an upper support space 21 and a lower support space 22, and the second protective cover 3 includes an outer end face 31, an inner end face 32 and a transverse extension portion 33; the outer end face 31 matches and snaps together one end of the LED light strip 1, and the upper support space 21 matches and snaps together the other end of the LED light strip 1; an outer end face hole 34 is arranged on the outer end face 31 and is matched and connected with the fixed mounting hole 152 by means of bolts; a drainage hole 35 is arranged on the inner end face 32, which can drain water in time and achieve the effect of placing accumulated water; the transverse extension portion 33 covers the connection between the PCB board 8 and the power supply line 9, which plays a role in aesthetics. Preferably, a wire end opening is provided at one end of the LED light strip 1, and the wire end opening enables the installation of a wire buckle 6 after the second protective cover 3 is installed at the end of the LED light strip 1, so as to protect the wire end. Preferably, both the first protective cover 2 and the second protective cover 3 are plastic covers, and ribs are provided in the plastic covers, and the ribs can contact the PCB board 8 for fixing the PCB board 8.
