The light source of the lighting apparatus is an incandescent lamp and a fluorescent lamp. Recently, an LED is used.

LED has a variety of advantages such as high illuminance, low power consumption, semi-permanent life span, environment-friendly and emotional lighting, and has recently become a popular light source for lighting fixtures.

Recently, LED lights have been widely used in homes, lecture halls, offices, factories and underground parking lots.

However, in order to use a general LED light, it is necessary to replace a socket and a ballast provided in the existing fluorescent lamp apparatus. Therefore, in order to replace the LED light, the initial charging cost is excessively increased. The use thereof is limited.

Therefore, in order to use a socket and a ballast provided in existing fluorescent lamp apparatuses, an LED fluorescent lamp having replaced only a light source with an LED has attracted much attention in recent years.

Typically, the LED fluorescent lamp is configured such that an LED module (light source) having a plurality of LED lamps mounted on a hemispherical base frame is mounted, and a light-transmitting cover is coupled to a lower portion of the base frame to uniformly distribute the light of the LED light source. And a side cap having a pair of connection terminals to be coupled to the installed fluorescent lamp socket is coupled to both sides of the base frame and the transparent cover.

As a prior art related to the LED fluorescent lamp, there is a registered patent No. 10-0866586 (October 28, 2008)

The invention comprises a body comprising a hemispherical base and an extension bent inwardly from both ends of the base; A heat radiating blade formed along the longitudinal direction inside the base of the main body and for increasing the radiating efficiency to increase the radiating efficiency; A plate mounted on an extension of the base, and a receiving protrusion connected to both sides of the plate; An LED module mounted between the receiving protrusions of the fixing portion and comprising a PCB substrate on which a plurality of LEDs are mounted; A cap which covers the main body and has a hemispherical shape and has a thickness at both sides relatively thinner than an upper center of the cap to increase a transmission amount of light radiated to both sides to expand a directivity angle of light emitted from the LED module; The cap has a lower end portion formed with a corresponding insertion portion to be coupled to the insertion portion, and the insertion portion and the corresponding insertion portion exhibit elasticity when the body and the cap are attached to and detached from each other, Detachment means for ensuring ease of engagement and disassembly of the body and the cap; And a fixed cover fixedly connecting both ends of the main body and the cap after coupling the cap and the cap.

Accordingly, the LED fluorescent lamp according to the present invention can be directly coupled to a pre-installed fluorescent lamp socket without replacing a socket for power supply,

Installation of such an LED fluorescent lamp is completed by inserting one side connection terminal into one side of the fluorescent lamp socket and inserting the other side terminal into the other side of the fluorescent lamp socket as in the conventional fluorescent lamp installation.

When replacement of a fluorescent lamp is required, the fluorescent lamp is turned off and then the above method is reversed so that one connection terminal is disconnected from the socket, and then the other terminal is disconnected to complete the separation operation.

However, when the LED fluorescent lamp is separated from the fluorescent lamp socket after being turned off,

The discharge of the thermoelectrons in the vacuum tube is stopped when the lamp is turned off so that the current is not energized in the vacuum tube so that the energization between both connection terminals is immediately blocked.

The remaining power is left in the LED substrate module in a state where only one connection terminal is disconnected after the LED light is turned off and the remaining power is discharged through the separated one connection terminal since both connection terminals are energized by the LED substrate module,

Therefore, if the operator touches the separated one connection terminal during the separation operation, there is a problem that an electric shock accident occurs due to the residual power source.

Also, even after the LED fluorescent lamp is completely separated from the fluorescent lamp socket, the residual power source remains in the LED module for a certain period of time, so that the residual power source is discharged through the connection terminal.

There is a risk of an electric shock due to the residual voltage since the lamp is usually turned off and replaced when the fluorescent lamp is replaced,

Particularly, in the operation of separating the fluorescent lamp from the socket for a fluorescent lamp, since the connection terminal 41 on one side is firstly separated from the socket on the other side and then the other connection terminal 41 is separated,

If the operator makes contact with the disconnected one-side connection terminal 41 in a state where the other-side connection terminal 41 is connected to the socket, there is a great risk that an electric shock accident will occur when the residual voltage is energized through the connection terminal 41.

Accordingly, when separating the connection terminal 41 from the fluorescent lamp socket, the residual power of the LED light source 10 is energized through the disconnected connection terminal 41, so that when the user touches the connection terminal 41, The electric shock prevention means 100 is introduced.

And disconnects the connection terminal (41) and the LED light source (10) from each other at the time of withdrawing from the main body (110).

That is, when the switch 120 is coupled to the fluorescent lamp socket while being exposed to the outside of the side cap 40, the exposed portion 120A of the switch 120 contacts the inner surface of the socket, So that the connection terminal 41 and the LED light source 10 are energized to supply power to the LED light source 10 so that they can be turned on and off,

When the connection terminal 41 is disconnected from the socket, the switch 120 is released from the main body 110 and the connection terminal 41 and the LED light source 10 are energized It is possible to prevent an electric shock accident from occurring even if the operator touches the separated connection terminal 41. [

2 to 6, in order to realize the connection or disconnection between the connection terminal 41 through the switch 120 and the LED light source 10,

The main body 110 includes a barrel 113 connected to the terminal hole 42 connected to the connection terminal 41 so as to be electrically connected,

The connection powder 117 is coupled to the LED light source 10 so as to be energized so that the connection powder 117 reciprocates in the main body 110 according to the drawing of the switch 120, And a connection member 116 which is connected to or disconnected from the tube 113.

At this time, the switch 120 and the connection member 116 are directly connected to each other so that the outflow of the switch 120 can be performed by reciprocating movement of the connection member 116,

Generally, the width of the socket on which the conventional fluorescent lamp is installed may be different by a predetermined length due to the maker or manufacturing error,

Therefore, when the displacement distance of the connection member 116 due to the outflow of the switch 120 is limited to a predetermined interval, the switch 120 is not operated and the LED fluorescent lamp can not be used,

Or an LED fluorescent lamp can not be installed in a socket for a fluorescent lamp.

That is, for example, when the widths of both sides of the fluorescent lamp socket are larger than the distance between the ends of the exposed portions 120A of the switches 120 exposed to the outside of the side-surface caps 40 of the present invention,

When the LED fluorescent lamp is connected to the socket, any one or both of the switches 120 do not contact the inner surface of the socket, and the switch is not drawn into the main body, so that the power supplied through the connection terminal 41 is LED A problem that the light source 10 is not energized may occur (hereinafter referred to as " Problem 1 "),

Or when the widths of both sides of the fluorescent lamp socket are smaller than the distance between the ends of the exposed portion 120A when the both side switches 120 of the present invention are fully drawn (hereinafter referred to as Problem 2)

The second elastic body 119 is configured to have an elastic force stronger than the elastic force of the first elastic body 118,

The elastic force of the first elastic body 118 is weaker than the elastic force of the second elastic body 119 so that only the first elastic body is pressed so that the switch 120 All of the connecting members 116 simultaneously move toward the barrel 113 and the connected powder 117 is connected to the barrel 113,

And the switch 120 moves backward toward the connection member 116 after connection.

The connection terminal 41 is electrically connected to the LED light source 10 only by connecting the connection terminal 41 to the fluorescent lamp socket when the LED fluorescent light is installed,

When the switch is detached to the outside of the main body, that is, to the outside of the side cap by the elastic members 118 (119) only by removing the connection terminal 41 from the fluorescent lamp socket when the LED fluorescent lamp is separated, (That is, the connecting portion 117B of the connected powder 117 and the connected portion 115B of the barrel 113 are separated from each other), it is very easy to replace the LED fluorescent lamp, Can,

In addition, in the present invention, when there is no problem such as the above-described problem 1 or 2, only the distance secured by the first elastic body 118 prevents the electric shock caused by the drawing-out of the switch 120, Electric power is supplied to the light source 10,

Further, since the switch 120 is drawn out to the end of the connection terminal 41 by the first elastic body 118 as much as possible, there is no problem in lighting the LED fluorescent lamp even in the case of the problem 1,

In addition, since the first elastic body 118 secures the maximum displacement of the switch 120 to the inside of the main body 110, the LED 120 can be drawn into the main body 110 as much as possible. Can be used.

This is because it is natural that the manufacturing error of the above-described fluorescent lamp socket occurs within the general specification of the fluorescent lamp, and the above-mentioned effect can be expected.
