Description

Technical Field

[0002] Light is one of the important factors affecting plant growth and development. Plant lamps are often used to adjust light and control plant growth patterns. Existing plant lamps mostly include a lamp body module and a driving power box for controlling the light emission of the lamp body module. The lamp body module is relatively large and cannot be folded, which affects the convenience and cost of transportation.

[0003] A patent document with application number 201910707099.1 in China and publication date 2020.2.1 discloses a lighting device with a cableway; it has a first lighting fixture and a second lighting fixture, and the first lighting fixture and the second lighting fixture are connected in a movable relationship between a storage position and a deployed position by a connecting element that applies a blocking torque. The connecting element can be a connecting shaft that provides friction, or a friction hinge cylinder. The hinge has a ledge surface adjacent to the rotating hinge surface and extending transversely to the rotation plane. The horticultural lighting device has an articulated cableway that extends through the hinge connecting the lighting fixtures and guides the cables entering from the outside into the cable path in the lighting fixture.

[0004] However, when the lighting device is folded, one lighting device needs to be folded over the other lighting device; the thickness of the folded lighting device increases to twice the thickness of the lighting device before folding; the thickness of the package is increased, which is inconvenient for transportation; when folding is required, one lighting device is connected to another lighting device only by a hinge, so that one lighting device and another lighting device cannot be in the same straight line after long-term use, resulting in poor structural stability; in addition, the position of the light strip on the lighting device is fixed, so that even after folding, its width direction is fixed, resulting in a large packaging size. Summary of the invention

[0005] The invention provides an LED lamp with adjustable size and good fixing effect and an adjustment method.
