Description

  The present invention relates to an LED lamp, and more particularly to a structure for attaching and detaching an LED lamp.

  LED (Light Emitting Diode) has advantages such as low energy consumption, saving power consumption, long life, small volume, fast reaction speed, etc. Widely applied in lighting fixtures or light emitting devices. In these illumination lamps or light-emitting devices, an LED module is usually formed by soldering a plurality of LEDs and a circuit board to increase the irradiation range and brightness. Thereafter, a light-transmitting cover and a heat dissipation cover made of metal are joined to the LED module. However, since the translucent cover and the heat dissipation cover are manufactured from different materials, it is necessary to use a locking member such as a screw when assembling them together.

  The conventional LED lamp mainly includes an LED circuit board, a translucent cover, a heat dissipation cover made of metal, and two terminal units. The above-mentioned members are combined together by a locking member such as a screw to constitute an LED lamp.

  However, the conventional LED lamp has a problem in actual use. In order to assemble or disassemble the LED lamp, the user needs to carry a tool such as a screwdriver when tightening a locking member such as a screw. At this time, the user needs to support a member for assembly (or disassembly) in the LED lamp with one hand, and the other hand is very inconvenient because the screw must be tightened with a screwdriver. . In addition, the user may drop the screw during the tightening operation.

  In addition, since the translucent cover is usually made of thin plastic, when the user assembles the LED lamp using screws, if the urging (spring) force is too large, the screw hole of the translucent cover made of plastic will be damaged. there's a possibility that. As a result, assembly of the entire LED lamp becomes difficult, and the entire LED lamp may need to be replaced.

Thereafter, the substrate 21 to which the engagement member 30 is inserted and connected is disposed in the direction of the cover plate 10, and the engagement connection step 33 of the engagement member 30 is inserted and connected to the fixing portion 12 of the cover plate 10. Thereby, the cover plate 10, the engaging member 30, and the LED module 20 are integrally connected and fixed.

  Next, the engagement edge 42 of the cover body 40 is fitted into the engagement groove 16 of the cover plate 10, and the LED module 20 is disposed in the accommodation space 41 of the cover body 40 (see FIG. 3). Thereafter, the terminal plug 242 of the end lid 24 is inserted into the corresponding terminal socket 212 on the substrate 21. Finally, the two end lids 24 are respectively covered from the end portions to the end portions of the lid plate 10 and the cover body 40, and the engagement portions 241 of the end lid 24 are engaged with the engagement holes 14 of the lid plate 10 and the cover body 40. Engages with the joint hole 43. Thereby, the entire assembly is completed. FIG. 4 is a transparent perspective view showing a state after the assembly is completed. FIG. 5 is a cross-sectional view showing a state after the assembly is completed.

  Since the disassembling process is basically in the reverse order of the assembling process, redundant description will not be given. Here, the reason for disassembling the LED lamp is usually when many of the LEDs 22 are damaged and the brightness of the LED lamp is insufficient, or when the user wants to change to the LED 22 of another color. , Is replaced with a new substrate 21 (which naturally includes a plurality of LEDs 22 connected on the substrate 21). When disassembling the LED lamp according to the present embodiment, first, the end lid 24 and the cover body 40 are removed. Next, the terminal plug 242 is removed from the terminal socket 212. Thereafter, the insertion step 31 of the engagement member 30 is pressed inward, the engagement block 312 of the elastic arm 311 is contracted inward, and the elastic support with respect to the insertion hole 210 of the substrate 21 is released. Can be removed. Thereafter, a new substrate 21 may be disposed based on the assembly step. If not necessary, the engagement member 30 does not have to be separated from the fixing portion 12 of the cover plate 10 in the disassembling process, so that the life of the engagement member 30 can be extended.

  This will be described with reference to FIG. FIG. 6 is an exploded cross-sectional view illustrating an LED lamp mounting / removal structure according to another embodiment of the present invention. In the present embodiment, the fixing portion 12 ′ of the cover plate 10 includes two engagement connection plates 120 ′ extending from the cover plate 10, and an insertion groove 121 ′ is defined between the two engagement connection plates 120 ′. Then, a difference from the above-described embodiment is that a pair of elastic flange portions 331 ′ fitted and fixed to the insertion groove 121 ′ are formed in the engagement connection step 33 of the engagement member 30.
