Description

A combined LED lighting lamp

technical field

The invention relates to an LED illuminating lamp, more specifically, to a combined LED illuminating lamp spliced by multiple units.

Background technique

As LEDs are more and more applied to lighting lamps as a new type of light source, LED lighting lamps have entered the stage of mass production. In order to improve production efficiency, the light source is usually modularized, that is, multiple LED light sources are integrated into one light source mold strip, and then a plurality of such light source mold strips are assembled into a whole lamp through a certain structure. In the previous production process of LED lamps, each lamp was composed of various parts. Therefore, the process of assembling the lamps is very complicated, which will inevitably lead to low production efficiency. At the same time, because each lamp has a large number of parts, it will also Cause the working reliability of lamps and lanterns to reduce. In addition, when a fault occurs during on-site use and needs to be repaired, the electrode leads of ordinary LED lamps are usually sealed and fixed by colloid. When disassembling, destructive methods must be used to remove the light source mold strip, which causes great damage to the on-site disassembly and assembly. Big inconvenience.

detailed description

The technical solution of the present invention is described in detail below by means of the accompanying drawings and specific embodiments:

As shown in FIG. 1 , an embodiment of the combined LED lighting provided by the present invention is formed by splicing two lighting units 3 . The two lighting units 3 are respectively fixed on the first end cover 1 and the second end cover 2 provided at both ends thereof by means of screw connection. The external power supply is connected to the first end cover 1 through cables to provide working voltage for the lighting unit 3 .

As shown in FIG. 2 , a schematic cross-sectional view of the lighting unit 3 , the LED lighting lamp in this embodiment is reflective, and a reflector is placed above the LED light source. The first profile 5 used in the shell is in the shape of a long strip. The LED light source is welded on the light source mold strip circuit board 6, and the light source mold strip circuit board 6 is pasted on the second profile 7 by high thermal conductivity glue, and the second profile 7 is inserted into the slot provided on the first profile 5 to fix. A glass cover 8 is installed at the light outlet of the lighting unit 3 , and a sealing strip 9 is installed between the glass cover 8 and the first profile 5 . The first profile 5 and the glass cover 8 are sealed and fixed by the third profile 10 outside the first profile 5 .
