Description

Technical Field

[0001] The utility model relates to the technical field of lighting, in particular to a simple light string. Background Art

[0002] Light strings consist of multiple lamp holders connected in parallel or series. To prevent short circuits caused by lamp holder damage, protective devices must be installed within the light string. Conventional technologies require a plastic housing specifically designed to house the protective devices within the outer shell of each lamp holder, which increases the overall size of the lamp holder, significantly increases production costs, and is inconvenient for daily use. Utility Model Content

[0003] In order to solve the above problems, the purpose of the present invention is to provide a simple light string, ensure the protection performance of the lamp holder and reduce the production cost of the light string.

[0004] The technical solution adopted by the utility model to solve the problem is:

[0006] The above-mentioned simple light string has at least the following beneficial effects: by setting the first lamp head and the second lamp head, the stability of the simple light string can be ensured by the light-emitting component and the shell, and the number of protective devices can be reduced while ensuring the protective performance of the simple light string, thereby reducing the production cost of the light string and improving the safety and service life of the simple light string; by setting the connecting block and the base, the first lamp head and the second lamp head can be quickly and stably installed on the wire, avoiding the light-emitting component and the protective device from loosening during installation and use, thereby improving the production efficiency and structural stability of the simple light string.

[0007] Furthermore, the buckle is provided with a positioning hole that cooperates with the fixing block. By providing the positioning hole, the buckle can be quickly and stably fixed on the base, thereby improving the assembly convenience and structural stability of the housing.

[0008] Furthermore, the buckle is integrally formed with the connecting block. This structure ensures the integrity of the buckle and the connecting block, prevents the buckle from loosening during use, and improves the structural stability of the simple light string.

[0009] Furthermore, the height of the fixing block gradually decreases as it approaches the base. This structure ensures that the fixing block can be quickly and stably fixed in the positioning hole, and also prevents the buckle from falling off during use, affecting the connection stability between the connecting block and the base.

[0010] Furthermore, the first lamp holder is located between the plurality of second lamp holders. This structure reduces the number of protective components, lowers the production cost of the light string, and improves the safety and service life of the simple light string.

[0011] Furthermore, the ratio of the number of the second lamp caps to the number of the first lamp caps is greater than or equal to 3. This structure effectively reduces the number of protective components while ensuring the protection performance of the simple light string, thereby reducing the production cost of the light string.

[0012] Furthermore, the connecting block is provided with a through hole, through which the first and second lamp caps are secured to the connecting block by passing the leads of the light-emitting assembly through the through hole. The provision of the through hole facilitates quick electrical connection of the first and second lamp caps to the wires via the leads, thereby improving the ease of assembly of the simple light string.

[0013] Furthermore, the base is provided with a terminal electrically connected to the wire, and the light-emitting component is connected to the terminal via the lead. The provision of the terminal facilitates quick and stable connection of the wire and the lead, thereby ensuring the structural stability of the simple light string.

[0014] Furthermore, the protective device is a current-limiting resistor. A current-limiting resistor is connected in series in a circuit to limit the current in its branch circuit to prevent excessive current from burning out connected components. The current-limiting resistor also acts as a voltage divider. Using a current-limiting resistor as a protective device improves the protective performance of the simple light string.

[0015] Furthermore, support platforms are provided on both sides of the base. By providing the support platforms, the base can be stably fixed, so that the connecting block can be accurately and quickly inserted into the base, thereby improving the production efficiency of the simple light string.

[0035] The working principle of the present utility model is further described below.

[0036] In the production process of the simple light string in this embodiment, first, a lampshade 111, a connecting block 121, and a base 122 of corresponding sizes are selected according to the specifications of the light-emitting device 112 and the protective device 130.

[0037] During use, the light-emitting devices 112 of the first lamp head 100 and the second lamp head 200 are connected to the external power supply through the wire 300 and emit light to achieve a lighting effect; at the same time, the protection device 130 in the first lamp head 100 spaced between the second lamp heads 200 plays a role in limiting voltage and current, thereby preventing the light-emitting device 112 from causing damage to other light-emitting devices 112 and the wire 300 in the event of a failure, thereby ensuring the protection performance and service life of the simple light string.
