This application claims priority to a Chinese Patent Application No. CN 202210543140.8, filed on May 18, 2022.
The invention relates to a lighting device, in particular an interconnected strip lamp.
In the context of energy saving and environmental protection, LED lamps are increasingly used in home and commercial lighting fields because of their high light-emitting efficiency and good light-gathering performance. As with the continuous improvement of people's quality of life, the demand for home and commercial lighting is also increasing.
When adjusting the range of the illumination space, adjustment of the irradiation range of the corresponding lamp is also needed. In particular in commercial lighting situation such as showcases, the range of illumination required is determined by the number of specific showcases. Therefore, by plugging and interconnecting LED strip lamps with given length, the illumination range can be adjusted conveniently and quickly.
In the prior art, the length of the hard strip lamp cannot be adjusted, which lead to that, multiple lengths of strip light or customized sections of strip light are required to lay out areas of different lengths to meet the demand. Thus manufacturing cost is greatly increased, moreover it is not convenient to install.
In view of this, the present invention provides an interconnected strip lamp to solve the above technical problems.
A An interconnected strip lamp, comprising a strip lamp holder, a strip circuit board set on the strip lamp holder, a light source chip set on the strip circuit board, an optical element set above the light source chip, and, a male plug and a female plug set at both ends of the strip lamp holder, wherein the strip circuit board is made of a flexible board and is provided with a conductive layer extending along the length direction on the back side.
Preferably, the male plug comprises:
Preferably, exposed surface of the conductive elastic member is set on the same side as the light source chip.
Preferably, the plug base and the strip lamp holder are integrally formed.
Preferably, the female plug comprises:
Preferably, the front side of the connecting base is provided with a necking corresponding to the connecting notch to block the side edges of the strip circuit board.
Preferably, the connecting base and the strip lamp holder are integrally formed.
Preferably, connecting base is provided with a convex part for restricting end of the strip circuit board.
Preferably, the strip lamp holder is linear, L-shaped, Y-shaped, cross-shaped or V-shaped.
Preferably, the optical element is a strip lamp cover.
The technical effects of the present invention:
The interconnected strip lamp of the present invention enables the users to cut the strip circuit board and the strip light holder as required. And because the strip circuit board is made of flexible board and the back side is provided with a conductive layer extending along the length direction, so it can be interconnected and conducted normally after any cutting, which makes the installation of the interconnected lamp more convenient, and also reduces the installation cost.
Embodiments of the present invention will be described below with reference to the drawings, in which:
Specific embodiments of the present invention will be described in further detail below based on the drawings. It should be understood that the description of the embodiments of the present invention herein is not intended to limit the protection scope of the present invention.
As shown in
For the interconnected strip lamp of the present invention, the direction of the optical element 400 with respect to the light source chip 300 is defined as frontward and the other opposite direction is defined as backward. Then the optical element 400 is provided on the front side of the strip lamp holder 100.
Because the strip circuit board 200 is made of a flexible board and is provided with a conductive layer 201 extending along the length direction on the back side, so it can be interconnected and conducted normally after any cutting, which makes the installation of the interconnected lamp more convenient, and also reduces the installation cost.
Interconnected strip lamp is a lamp that extends along its length direction. In this embodiment the strip lamp holder 100 is linear, and this specification is widely used.
In this embodiment, the male plug 500 comprises: a plug base 501 connected to the strip lamp holder 100, and the connection can be achieved by means of fastening through plug-in or fastener; and a conductive elastic member 502, fixed on the plug base 501, electrically connected at one end to the strip circuit board 200. The conductive elastic member 502 can be made in many ways, such as elastic needle, elastic sheet, etc. In this embodiment, the conductive elastic member 502 is form by bending conductive sheet, thus is simple in structure and easy to manufacture.
In this embodiment, the exposed surface of the conductive elastic member 502 is set on the same side as the light source chip 300. Due to above setting, when the lamps are interconnected, conductive elastic member 502 is inserted into the adjacent lamp and interconnected to the back side of the circuit board, thus can achieve the purpose of no dark area.
In this embodiment, the female plug 600 comprises a connecting base 601 and a connecting notch 602; connecting base 601 is connected to the strip lamp holder 100, and the connection can be achieved by means of fastening through plug-in or fastener. The strip circuit board 200 is extended and mounted to the connecting base 601; a connecting notch 602 is provided at the bottom of the connecting base 601, the back side of the strip circuit board 200 is oriented with the opening of the connecting notch 602. The connection notch 602 is also provided with a snap structure to prevent the plug base 501 from detaching.
When interconnecting, the male plug 500 and the female plug 600 of the two interconnected strip lamps are mated and connected, while the male plug 500 inserted through the connection notch 602 at the bottom of the connection base 601 and then interconnected by the conductive elastic member 502 and the conductive layer 201 against each other.
In this embodiment, the connection notch 602 is further provided with a limit slot 603 inside. The plug holder 501 is provided with a block 503, which matches with the limit slot 603 to realize the restriction in the length direction.
