Description

Technical Field

[0001] This utility model relates to an electric light source technology, particularly a spotlight. Background Technology

[0002] Existing spotlights, including a base, a lamp holder on the base, and a light source inside the lamp holder, have a light-emitting and focusing effect on the inner surface of the lamp holder to project the light source in one direction. These spotlights are all manufactured independently, are large in size, and when used in a concentrated manner, the spacing between the spotlights is large. They can only be used to illuminate a large target area and cannot be used for point-based display or concentrated point-based display of patterns and text. Moreover, the manufacturing process is complex and the production cost is high. Summary of the Invention

[0003] The purpose of this invention is to provide a spotlight that can overcome one or more of the above-mentioned shortcomings, and when used in a concentrated manner, can perform point-to-point display and combined display of patterns and text. Moreover, it has a simple manufacturing process and low production cost.

[0004] This utility model spotlight is implemented as follows: it includes a base plate, a circuit set on the base plate, several LED light sources set on the circuit, and a lamp cup set on the LED light sources. The LED light source is one or more LED light source chips fixed on the LED chip base; or, the LED light source is one or more LED light source chips directly connected to the circuit. The lamp cup is cylindrical or trumpet-shaped, and the bottom periphery of the lamp cup is glued to the periphery of the LED light source, so that the LED light source is located in the middle of the bottom port of the lamp cup. The lamp cups on the several LED light sources are connected by connecting rods, so that the positional relationship between the lamp cups matches the positional relationship of the several LED light sources on the base plate. The several lamp cups and the connecting rods between the lamp cups are integrally processed together.

[0005] Preferably, several LED light sources are arranged in a vertical and horizontal manner on the base plate, or several LED light sources are arranged in curved lines on the base plate to form a specific pattern.

[0006] During manufacturing, an FPC or PCB circuit board is designed and manufactured according to the positions of several LED light sources. Then, using an adhesive process, several LED light sources are glued to the corresponding positions on the circuit board using automated equipment and connected to the circuit to obtain the power supply from the circuit. Then, the FPC or PCB circuit board is glued and fixed to the base plate. Several lamp cups, which are integrally processed (such as injection molded) and connected by connecting rods, are glued as a whole onto the FPC or PCB circuit board, so that the LED light source is located in the middle of the bottom port of the lamp cup.

[0007] Because the bonding of multiple LED light sources is carried out by automated equipment, the position of each LED light source is precise, and the bonding manufacturing efficiency is high. Since multiple lamp cups and the connecting rods between the lamp cups are processed as a whole, the positional relationship between the lamp cups is precise, and the manufacturing efficiency is high. Since the positional relationship between each lamp cup matches the positional relationship of multiple LED light sources on the base plate, multiple lamp cups can be bonded to the corresponding LED light sources in one go. The bonding accuracy is high, the bonding efficiency is high, and the manufacturing process is simple and the production cost is low.

[0008] Compared with existing technologies, this utility model has the advantages of being able to perform point-to-point display and combined display of patterns and text when used in a concentrated manner, and it also has the advantages of simple manufacturing process and low production cost.
