Description

Technical Field

[0001] This utility model relates to the technical field of lighting fixtures. Background Technology

[0002] Lighting fixtures, especially portable, adjustable-direction lighting tools such as flashlights and work lights, have become indispensable equipment in daily life and professional work. CN202132713U discloses an adjustable-direction flashlight, which includes a handle and a lamp head with a light-emitting element. The handle and lamp head are connected by a corrugated tube, which can undergo plastic deformation after expansion, contraction, and bending.

[0003] This type of lighting fixture can adjust the direction of illumination, but its function is relatively limited. The light can only be projected in one main direction, resulting in high intensity illumination from a single direction. This creates a strong contrast between the bright work area and the dark surrounding environment, which can easily lead to eye strain. In scenarios where both main target lighting and ambient lighting are needed, such as nighttime maintenance, camping, or reading, it cannot provide wide-area ambient lighting or create a suitable atmosphere.

[0004] Therefore, there is an urgent need to design a luminaire that can flexibly adjust the direction of illumination and provide a wider and softer ambient lighting. Utility Model Content

[0005] Therefore, to solve the above problems, this utility model provides a lamp.

[0006] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0007] A lamp includes a main body and a lamp head. A first light-emitting element is disposed inside the lamp head. The main body and the lamp head are connected together by a corrugated tube, which is plastically deformable and can transmit light. A second light-emitting element is disposed inside the corrugated tube. The main body is provided with a control unit, which is configured to control the working state of the first light-emitting element and the second light-emitting element.

[0008] Optionally, the second light-emitting element includes a flexible light strip.

[0009] Optionally, the first light-emitting element and the control unit are electrically connected via a wire harness.

Detailed Implementation

[0025] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention and are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. Components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0026] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0027] Example 1:

[0028] Reference Figure 1-6 This embodiment provides a lamp, including a main body 1 and a lamp head 2, with a first light-emitting element 4 disposed inside the lamp head 2. The main body 1 and the lamp head 2 are connected together by a corrugated tube 3, which is plastically deformable and allows light to pass through. A second light-emitting element 5 is disposed inside the corrugated tube 3. A control unit is disposed inside the main body 1, and the control unit is configured to control the working state of the first light-emitting element 4 and the second light-emitting element 5. Thus, through the stretchable and flexible plastic deformation of the corrugated tube 3, the lamp can not only flexibly adjust the illumination direction of the first light-emitting element 4, but also, through the combination of the second light-emitting element 5 and the light transmission of the corrugated tube, act as a lampshade to provide a wider and softer ambient lighting, adapting to various usage environments, such as reading and camping.

[0029] Furthermore, the second light-emitting element 5 includes a flexible light strip 51, which is connected between the main body 1 and the lamp head 2, thereby making the light intensity transmitted from all parts of the corrugated tube 3 more uniform. The second light-emitting element 5 is an RGB light-emitting element capable of emitting different colors of light, and the control unit is configured to control the light emission color of the second light-emitting element 5. That is, in this embodiment, the second light-emitting element 5 can be a flexible light strip 51 capable of emitting different colors of light.

[0030] Furthermore, the first light-emitting element 4 is electrically connected to the control unit via a wire harness 6. The wire harness 6 can be a spring wire harness, so that the stretchability of the wire harness 6 can better adapt to the stretching, bending and plastic deformation of the bellows 3.

[0031] Furthermore, refer to Figure 5 and Figure 6 The lamp holder 2 includes a first housing 21 and a second housing 22. The first housing 21 is connected to a bellows 3. A first light-emitting element 4 is fixedly installed inside the first housing 21. A convex lens is provided on the second housing 22. The second housing 22 is movably connected to the first housing 21 along the axial direction of the first housing 21, so that the distance between the convex lens and the first light-emitting element 4 can be changed, thereby adjusting the illumination range of the light beam emitted by the first light-emitting element 4 after passing through the convex lens. Specifically, the second housing 22 is slidably connected to the first housing 21. A certain damping friction force can be provided between the first housing 21 and the second housing 22, so that the distance between the first light-emitting element 4 and the convex lens can be kept stable through friction. In other embodiments, the second housing 22 can also be threadedly connected to the first housing 21. A limiting structure is provided between the first housing 21 and the second housing 22 to prevent the second housing 22 from completely detaching from the first housing 21. The limiting structure can be a combination of a limiting block and a limiting groove, or other structures, as long as they can limit the maximum relative sliding stroke between the first housing 21 and the second housing 22.

[0032] Furthermore, the main body 1 is equipped with a handle 11, which is detachably connected to the main body 1. Specifically, the handle 11 is installed on the side of the main body 1 away from the lamp head 2. The handle 11 allows the lamp to be hung on other external objects, such as hooks. Both ends of the handle 11 are detachably connected to the main body 1, and the handle 11 is a flexible plastic strip. This design facilitates hanging the lamp on external objects. For example, when camping, the ends of the connecting pole at the top of the tent are closed. In this case, one end of the handle 11 can be detached from the main body 1, wrapped around the connecting pole, and then reattached to the main body 1. This allows the connecting pole to pass through the closed loop formed by the handle 11 and the main body 1, thus enabling the lamp to be hung. Rivets can be fixed on both sides of the main body 1. There is a gap between the rivet head and the side wall of the main body to facilitate the installation of handle 11. Mounting holes are opened at both ends of the handle 11. Since the handle 11 is made of flexible plastic strip, the end of the handle 11 can be opened through the mounting hole and installed into the gap between the rivet and the side wall of the main body 1.

[0033] Furthermore, a magnetic element 13 is provided on the side wall of the main body 1. In this embodiment, the magnetic element 13 is installed on the side wall of the main body 1 away from the lamp holder 2, so that the entire lamp can be attracted and fixed to the metal surface. The installation position of the magnetic element 13 is not limited here.

[0034] Furthermore, the control unit can control the turning on and off of the first light-emitting element 4 and the second light-emitting element 5, as well as their light-emitting modes and brightness. In this embodiment, the control unit is configured to independently control the turning on and off of the first light-emitting element 4 and the second light-emitting element 5. This allows it to adapt to a wider range of usage environments.

[0035] Furthermore, the control unit can control the first light-emitting element 4 and the second light-emitting element 5 via buttons, touch, voice control, or wireless control via Bluetooth through a mobile app. In this embodiment, button control is used. That is, operation buttons 12 connected to the control unit are disposed on the side wall of the main body 1.

[0036] Example 2:

[0037] Reference Figure 7 In this embodiment, unlike in Embodiment 1, the second light-emitting element 5 includes at least two lamp plates 52 with light sources arranged on them, and the lamp plates 52 are spaced apart along the length of the corrugated pipe 3. By using the spaced lamp plates 52, the corrugated pipe 3 can be made relatively uniform in terms of light transmission without hindering its expansion, contraction, and bending.

[0038] Specifically, there are two lamp panels 52, defined as a first lamp panel 521 and a second lamp panel 522. The first lamp panel 521 is fixedly installed on the side of the main body 1 facing the lamp head 2, and the second lamp panel 522 is fixedly installed on the side of the lamp head 2 facing the main body 1. The light sources of the two lamp panels 52 are arranged facing each other. The second lamp panel 522 is electrically connected to the control unit via a wiring harness 6. The first light-emitting element 4 is connected to the circuit on the second lamp panel 522 via a wire, thereby making the first light-emitting element 4 electrically connected to the control unit via the wiring harness 6. The control unit can independently control the first lamp panel 521, the second lamp panel 522, and the first light-emitting element 4, so that the working state of the three can be controlled separately. Of course, the working states of the first lamp panel 521 and the second lamp panel 522 can also be controlled synchronously, or the first light-emitting element 4 and the second light-emitting element 5 can be controlled synchronously.

[0039] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
