Description

Variable-length LED lamps {Variable-length LED lamp}

The present invention relates to a variable-length LED lamp, and more particularly to an LED lamp that can be installed to reduce the length and increase freely according to the conditions of the lamp installation place.

In general, lamps used in daily life include fluorescent lamps, incandescent lamps, etc., and these lamps are operated by AC power, and have a disadvantage in that the power consumption and the brightness are high, but the life and illuminance of the lamps are degraded when operated for a long time. .

For example, fluorescent lamps or incandescent lamps must be replaced after a certain period of time due to deterioration of lamp life and brightness.

Because of this short lifespan, once the lamp has been replaced, the hassle of having to replace the lamp without using it for several years and the enormous cost of the lamp replacement are high.

Therefore, in recent years, there is a tendency to replace a lot of LED lamps with the advantages of low operating voltage, fast response speed, small size and long operating life.

In general, LED is excellent in converting power to light, and thus is widely used for a display or an indicator.

Recently, due to the development of a blue LED and a white LED that can supply white light by using a fluorescent material having an emission spectrum corresponding to red and green, research on the use of the LED as an illumination is being actively conducted.

Compared to incandescent lamps and fluorescent lamps, which are currently used, the efficiency of light is much higher than that of unit power, and the economic efficiency is excellent. Moreover, the amount of light can be obtained even at low voltage. It is a trend.

Currently used LED lamp is composed of an integrated lamp in which the LED module and SMPS are integrally combined in the case, and is installed in a structure that connects using a socket on the top of the case.

However, conventional standardized integrated LED lamps have a narrow disadvantage of application, that is, a narrow range of application.

For example, in the case of replacing an existing fluorescent lamp or incandescent lamp with an LED lamp, the specification is different due to the various conditions of the place where the fluorescent lamp or the incandescent lamp is installed, that is, the depth of each housing in various places is varied. There are a few limitations in LED lamps that cannot accommodate them all.

For example, when the depth of the housing is deep, the LED lamp is installed too deep inside, the case that the LED lamp is not able to serve as a problem occurs, and when the depth of the housing is shallow, the LED lamp protrudes out to damage the appearance. There is a case.

However, it is not only economically inefficient and inefficient to manufacture various types or specifications of LED lamps according to the conditions of various places where the lamps are installed, but there are also many difficulties in reality.

Therefore, the present invention has been devised in view of the above, a new type of lamp installation method for manufacturing the LED module and SMPS in an external structure and installing in a structure that supports using a variable length member when installed within the depth of the various housings By implementing the LED lamps, LED lamps can be installed according to various conditions of the lamp installation place, that is, according to the depth of various housings, and accordingly, the purpose is to provide a variable length LED lamp that can promote work efficiency and economy. There is this.

In order to achieve the above object, the variable-length LED lamp provided by the present invention can receive power from the outside and is electrically connected while being coupled up and down in the form of one assembly, and one end to the ceiling-side housing. At the same time, the other end is connected to the bracket in the SMPS, and includes a variable length member such as a stretchable tension spring, etc., and by installing the SMPS and the LED module in accordance with the depth of the housing in which the lamp is installed, It can be used to apply all the various conditions of the place where the lamp is to be installed.

The variable length LED lamp of the present invention provides the following advantages.

When replacing the LED lamp in the place where the existing fluorescent lamp or incandescent lamp is installed, or when installing the LED lamp in the housing having various installation depths, adjust the length of the variable member, for example, the spring Since the LED lamp can be installed in various installation places, the compatibility and application of the LED lamp can be expanded, and it can be applied to the conditions of various installation places with only one type or standard. There is an advantage.

In addition, when newly installed, it can be installed as a very simple structure without making it as complicated as existing luminaires, and can be expected to save a lot of time in terms of economy and ease of installation.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

As shown in Figures 1 to 3, the LED lamp is made of a structure that can be used to adjust the position of the SMPS 10 and the LED module 11 to the depth of the housing 12, accordingly various depths As having, there is a feature that can actively cope with the various housing (12).

To this end, the SMPS 10 and the LED module 11 is in the form of an external type, that is, not surrounded by a separate case or protective cover (built-in type), it is formed in a form that can be used as a single unit itself.

The SMPS 10 and the LED module 11 are arranged up and down and are integrally combined to form an assembly form through a plurality of screw fastening structures, and the LEDs are electrically connected to each other and controlled by the SMPS 10. The module 11 can be operated.

Here, although not shown, a separate wire is provided between the interface between the SMPS 10 and the LED module 11, so that the SMPS 10 and the LED module 11 may be electrically connected to each other.

The SMPS 10 has a form in which a SMPS unit (not shown) is built in the body, and the LED module 11 includes a plurality of LED elements 18 and light emitting means disposed on a bottom thereof. And a heat sink 20 for dissipating heat generated from 18).

In addition, a bracket 13 having a hole 22a is coupled to the upper portion of the body of the SMPS 10, and the bracket 13 becomes a part capable of hanging the variable length member 14 described later.

In addition, an upper portion of the SMPS 10 is provided with a wire 16 drawn out to one side of the bracket, and the wire 16 extends upward and is a one-touch connector 17 provided on the upper portion of the housing 12. Is connected to.

Accordingly, when the power line from the outside is connected to the other side of the connector 17, the power can be supplied to the SMPS 10 through the wire 16.

Here, it is preferable for the wire arrangement 16 to be connected to the housing 12 side connector 17 by extending along the inner path of the length-variable member 14 which will be described later, that is, the inner space formed inside. can do.

Of course, in the case of the wire 16, it is good in terms of workability to connect using an outer space rather than the inside of the variable length member (14).

The LED module 11 has a position fixing plate for matching between the bottom of the housing 12, that is, the flange 21, while contacting the bottom of the SMPS 10 and the LED module 11 and the bottom of the housing 12 during installation. 15 is provided.

The position fixing plate 15 is formed in the shape of a disc with a central portion corresponding to the arrangement area of the LED elements 18, the position fixing plate 15 is the SMPS (10) and by the elasticity of the variable length member (14) When the LED module 11 is pulled upward, the LED module 11 is caught while being in close contact with the bottom surface of the flange 21 of the housing 12, so that the installation position of the SMPS 10 and the LED module 11 matches with the bottom of the housing to be fixed. It becomes possible.

In addition, a transparent or translucent cover 19 is provided to be coupled to the bottom of the LED module 11 to protect the LED elements 18 from an external environment.

In the present invention, the variable-length member 14 is provided as a means capable of substantially varying the installation positions of the SMPS 10 and the LED module 11.

The variable length member 14 can be applied without any particular limitations to the shape, structure, material, etc. as long as it has a stretchable property, that is, it can be applied to a variety of forms such as tension springs, springs, pulley type roller springs, , The present invention provides an example of applying a tension spring that can be used by hanging both ends of the ring.

The variable length member 14, for example a tension spring, is located between the SMPS 10 and the LED module 11 at the top and bottom of the housing 12 inside the housing 12 and by using both ends of the ring. It is provided in a structure fitted between the housing 12 side hole 22b and the SMPS 10 side hole 22a.

Accordingly, the position of the SMPS 10 and the LED module 11 can be changed by using the stretching characteristics of the tension spring.

For example, when the depth of the housing 12 is deep, the tension spring may be increased to install and use the SMPS 10 and the LED module 11 to be positioned below.

Therefore, looking at the state of use of the variable-length LED lamp of the present invention configured as described above are as follows.

4A to 4D are cross-sectional views illustrating various usage states of the variable-length LED lamp according to an embodiment of the present invention.

As shown in FIG. 4A, first, a process of installing the SMPS 10 and the LED module 11 will be described.

First, a connector-attached wire (not shown) capable of connecting the wires 26 drawn from the SMPS 10 is first fixed to the connector 17, and then the length-variable member 14, for example, a tension spring Hook one of the hooks into the hole 22b in the upper part of the housing 12, and then connect the wire 26 to the wire connected to the connector 17 to terminate the power connection. Pulling the other end of the hook into the hole 22a of the bracket 13 in the SMPS 10 and the LED module 11, the SMPS 10 and the LED module 11 are pulled upward by the force of the tension spring. As a result, the lower position fixing plate 15 of the SMPS 10 and the LED module 11 is caught by the flange 21 of the housing 12, and thus the installation of the SMPS 10 and the LED module 11 is completed.

As shown in FIGS. 4B and 4C, when the size of the housing 12 installed on the ceiling 100 is large, that is, when the depth of the housing 12 is large, the tension spring is increased as much as the depth thereof. By compensating, even if only the SMPS 10 and the LED module 11 having a single standard has the advantage that all can be applied without problems even if the depth of the housing 12 is varied.

As shown in FIG. 4D, the SMPS 10 and the LED module 11 are directly installed on the ceiling 100 using the tension springs.

One assembly is provided with the SMPS (10) and the LED module (11) electrically connected while being coupled up and down, the hole (22a) of the bracket 13 in the SMPS (10) is a flexible variable length member ( 14) For example, one end of the tension spring is connected, and the other end of the tension spring is caught by the hole 22c in the ceiling 100.

Accordingly, the SMPS 10 and the LED module 11 may be used while being suspended from the ceiling 100 while being supported by the tension spring.

In this case, the wires 26 extending from the SMPS 10 are inserted into the ceiling 100 through the inside of the tension spring and connected to the connector (not shown) there, thereby providing an excellent aesthetic appearance. It becomes possible.

As described above, the variable-length LED lamp of the present invention uses the stretching action of the tension spring in the case of newly installing the LED lamp as a replacement for the existing fluorescent lamp or the incandescent lamp. Since it can be installed properly according to the requirements, only one type or standard LED lamp can be applied to various installation places, and both economic and efficiency can be satisfied.
