technical field

The utility model relates to the technical field of LED lighting, in particular to a conveniently installed LED desk lamp.

Background technique

LED desk lamp is a lighting fixture that has been widely used on desks or dining tables for reading, studying and working. There are generally two types of existing LED desk lamps: one is to directly replace the original incandescent lamp or fluorescent lamp with an LED bulb lamp as the light source and install it on the lamp holder in the lamp body of the desk lamp. The other is to directly adopt LED table lamp design, which has various design forms. The general structure includes driving power supply, LED light source board, reflector cup, lamp housing and light-transmitting board. The latter LED desk lamp structure usually consists of a lamp housing and a light-transmitting plate to form an installation cavity. The lamp housing is provided with a card slot and a mounting column, and the driving power supply, LED light source board and reflector cup are installed in the cavity. The conventional installation sequence is as follows: first snap the drive power supply into the slot inside the lamp housing, then fix the LED light source board on the mounting column inside the lamp housing, then connect the drive power supply and LED light source board by wire welding, and then Install the reflective cup above the LED light source board, and finally install the light-transmitting plate on the opening of the lamp housing. The structure of the lamp head of the existing LED table lamp makes it necessary to adopt the above-mentioned installation method. This installation process is not only cumbersome, but also because of the small space of the lamp housing, it is very inconvenient to operate inside, and there is also a problem of poor consistency.

Detailed ways:

The utility model provides a conveniently installed LED desk lamp. As shown in FIG. 5 , it is mainly composed of a lamp cap, a base 7 , and a connecting bracket 6 connecting the lamp cap and the base 7 . The utility model mainly improves the structure of the lamp holder, which will be explained mainly for the structure of the lamp holder below. The lamp cap includes a lamp housing 5 , an assembly and a light-transmitting plate 8 , wherein the assembly is formed by assembling a reflective cup 1 , an LED light source board 2 and a driving power board 3 as shown in FIGS. 1 to 4 . There is a mounting post 501 inside the lamp housing 5 , the combination is assembled in one body and then fixed to the mounting post 501 as a whole, and then the light-transmitting plate 8 is installed on the opening end of the lamp housing 5 . In the assembly, the LED light source board 2 and the driving power board 3 are respectively installed on the back of the reflective cup 1 . The reflection cup 1 is a trumpet-shaped structure with openings at both ends. The outer periphery of the wide mouth of the reflection cup 1 is provided with a radially protruding edge, and a plurality of mounting holes 101 for fixing are arranged at intervals on the edge. The mounting hole 101 cooperates with the mounting post 501 to fix the assembly inside the lamp housing 5 .

The fixing method of the LED light source board 2 and the driving power board 3 can be flexibly designed, and any existing method that can fix the LED light source board 2, the driving power board 3 and the reflective cup 1 in advance can be used. In this embodiment, only Two relatively simple structures are illustrated as examples.

The first structure: as shown in Figure 3, the first buckle column 102 is arranged symmetrically along the same direction on the back of the reflector cup 1, and the intersection of the first buckle column 102 on the back of the reflector cup 1 (vertically is the best) The direction is symmetrical with the second buckle column 103, and this cross layout can make full use of the limited space. The edge of the LED light source board 2 is provided with a bayonet, and the bayonet of the LED light source board 2 is snapped onto the first buckle column 102 to fix the LED light source board 2 . Similarly, a bayonet is also provided on the edge of the driving power board 3 , and the bayonet of the driving power board 3 is snapped onto the second buckle column 103 to fix the driving power board 3 .

The second structure: as shown in Figure 4, the first screw hole column 105 is arranged symmetrically along the same direction on the back of the reflective cup 1, and the first screw hole column 105 is intersected on the back of the reflective cup 1 (vertically is the best) The direction is symmetrical with the second threaded hole column 106, and this cross layout can make full use of the limited space. The edge of the LED light source board 2 is provided with round holes, and the round holes of the LED light source board 2 are aligned with the screw holes on the first screw hole column 105 and fixed with screws.
