Abstract
The present invention relates to lighting, and more particularly, to an LED lighting device for lighting using the LED. In particular, the present invention includes an LED substrate on which a plurality of LED elements are installed; The present invention provides an LED lighting device comprising a tubular member having a tubular member formed of a tubular material by which light of the LED element can be transmitted to insert the LED substrate and supporting the inserted LED substrate. .
Description
The present invention relates to lighting, and more particularly, to an LED lighting device for lighting using the LED.
In general, the lighting device is widely used as a lighting means such as indoor or outdoor lighting, a traffic light, a warning light.
As a lighting device, a filament that emits light while being heated to a high temperature when a current is supplied is used. In recent years, a lighting device using LED devices having low power consumption, excellent light brightness, and long lifespan are noted. Is getting.
However, the lighting device using the LED element has a solution to solve the problem of expensive manufacturing cost and ease of manufacture due to the price of the LED element itself, compatibility with existing external lighting equipment for fluorescent lamps, incandescent lamps, and simplification of structure. There is a great demand.
The present invention has been made to solve the above problems, an object of the present invention to provide an LED lighting fixture that can easily replace the existing lighting fixtures, such as fluorescent lamps.
In order to solve the above problems, the present invention includes an LED substrate having a plurality of LED elements installed; The present invention provides an LED lighting device comprising a tubular member having a tubular member formed of a tubular material by which light of the LED element can be transmitted to insert the LED substrate and supporting the inserted LED substrate. .
The plurality of LED elements may be arranged along at least the longitudinal direction of the tubular member, and installed to transmit light toward the width direction of the tubular member.
The LED substrate may be formed of a panel installed along the longitudinal direction of the tubular member, and the plurality of LED elements may be installed on one side of both sides of the LED substrate.
The support portion may be provided in pair so as to support both edges in the width direction of the LED substrate, respectively.
The tubular member may be provided with a plurality of protrusions on the outer surface of the LED element opposite to the light transmission direction.
The tubular member may be formed at least in front of the light transmitting direction side of the LED element curved along the circumferential direction of the tubular member.
The tubular member may further include a support protrusion protruding in the inner space of the tubular member toward the rear surface on which the LED element of the LED substrate is not installed to support the LED substrate.
The separation distance between the front surface of the LED substrate on which the LED element is installed and the tubular member may be longer than the separation distance between the rear surface of the LED substrate and the tubular member.
The support portion may be provided along the longitudinal direction of the tubular member.
The support portion may have a fitting space into which the LED substrate is fitted along the longitudinal direction of the tubular member.
At least one portion of the tubular member may be bent along the circumferential direction of the tubular member to have the support part.
At least one portion of the tubular member may be bent in a zigzag form along the circumferential direction of the tubular member such that the support part includes the fitting space.
The tubular member may be formed of synthetic resin.
Further comprising a cap coupled to at least one of both ends of the tubular member, the cap is at least one hook that is inserted into the insertion portion formed in the tubular member can be caught Can have
The cap may further include a cap coupled to at least one of both ends of the tubular member, and the cap may include at least one through hole communicating with an inner space of the tubular member.
The LED lighting device according to the present invention is a tubular member is made of a single cylinder, so the production of the tubular member is simple, and the overall assembly labor can be reduced.
In addition, the LED lighting apparatus according to the present invention may have an advantage that the LED substrate can be firmly supported by the support of the tubular member.
In addition, the LED lighting apparatus according to the present invention has a fitting space in which the support portion of the tubular member is fitted with the LED substrate along the longitudinal direction of the tubular member, the LED substrate can be easily assembled and separated in a slide manner, the tubular member of the Since the support portion is supported on both sides of the LED substrate, the bending deformation of the LED substrate and the like can be prevented.
In addition, the LED lighting device according to the present invention is bent one side of the tubular member is formed by the support, the tubular member can be further reinforced by the support, it can have the advantage that the resistance to bending deformation of the tubular member can be improved. have.
Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
