Description

CONNECTER UNIT FOR LINE TYPE LIGHTING DEVICE [0002]

The embodiment relates to a connector unit for a line-type illuminator and a line-type illuminator including the connector unit.

As a typical example of a light emitting device, a light emitting diode (LED) is a device for converting an electric signal into an infrared ray, a visible ray, or a light using the characteristics of a compound semiconductor, and is used for various devices such as household appliances, remote controllers, Automation equipment, and the like, and the use area of LEDs is gradually widening.

Light emitting diodes are attracting attention as lighting devices with high luminance and high efficiency.

In addition, a light emitting diode is conventionally used for a line type lighting device coupled to a fluorescent lamp socket.

However, there is a difference between the European standard and the Japanese standard in the conventional fluorescent socket.

As described above, the European standard has a distance between the sockets of 589.8 mm, and the Japanese standard has a distance of 580 mm between the sockets.

Therefore, there is a problem that the line type lighting apparatus must be manufactured to have a length corresponding to each socket specification.

Generally, the fluorescent lamp sockets are arranged in a mixture of the European standard and the Japanese standard.

Therefore, in a factory equipped with tens of thousands of sockets, the exact number of each socket specification can not be known, and the operator has to prepare a line-type lighting device according to each standard.

In addition, there is a problem that a manufacturer mistakenly orders an order quantity and accumulates inventory.

Generally, the fluorescent lamp apparatus includes a fluorescent lamp shade 10, which is formed by bending a steel plate into a predetermined shape by pressing and serving also as a reflector plate as shown in Fig. 1, and a fluorescent lamp shade 10, And a line type lighting device 30 which is supported by both ends of the socket 20 and is supplied with power and is lighted.

The embodiment provides a connector unit for easily coupling a line type lighting device to a socket of various specifications.

A connector unit for a line type illuminator according to an embodiment includes a connector cap coupled to one of end caps positioned at both ends of the line type illuminator, and a connector pin protruding from the connector cap and inserted and coupled to the socket, The connector cap includes a main plate on which the connector pin is located, a cylinder defining a space in which at least a part of the end cap is accommodated, and a positioning groove formed in the cylinder to determine a position of the end cap .

The embodiment has the advantage that the length of the line-type lighting device can be adjusted so that the line-type lighting device can be easily combined with the sockets of various specifications.

Further, in the embodiment, the connector pin is formed of an insulating material or an electrically conductive material, so that power can be supplied to the line-type lighting apparatus or short-circuiting can be prevented.

The embodiment prevents the connector pin from being damaged during loading or transfer because the connector pin is positioned inside the guider by the elastic member.

The line type lighting apparatus 100 according to an embodiment of the present invention includes a light source unit 110 having a plurality of point light sources and having at least one connection portion 113 at one end thereof, An end cap 120 which shields the opening of the optical housing 120 and accommodates the connection portion 113 of the light source unit 110 and the light source unit 110 and an external power source And a connector unit 200 for a line type illuminator coupled between the socket 20 and the end cap 130.

Referring to FIG. 2, the socket 20 fixes the line-type lighting device 100 and supplies power to the line-type lighting device 100.

For example, the two sockets 20 may be spaced apart from each other so that the line-type lighting apparatus 100 can be inserted between the spaced apart sockets 20. At this time, the terminal pin 141 of the line-type lighting apparatus 100 is inserted into the socket 20 and electrically connected to the socket 20.

In another example, the socket 20 includes a socket body 21 fixed to both sides of the fluorescent lamp shade 10 and a terminal pin 141 of the line-type lighting apparatus 100 inserted into the socket body 21 The terminal pin 141 is pulled into the socket body 21 through the lead-in groove 22 and is rotated 90 degrees to be in a horizontal state And a pair of female terminals 23 provided in the socket body 21 so that the contact with the terminal pins 141 is resiliently made.

In order to allow the terminal pins 141 of the line type lighting apparatus 100 to be smoothly drawn into the socket body 21 through the inlet grooves 22, There is formed a guide portion 24 in which a guide groove 25 formed in a straight line is formed.

Therefore, the terminal pins 141 provided at both ends of the line-type lighting apparatus 100 are vertically oriented while the fluorescent lamp shade 10 provided with the socket 20 is fixed to the ceiling surface on both sides of the bottom surface, When the terminal pin 141 is pushed into the socket body 21 through the lead groove 22 of the socket 20 and the line type lighting apparatus 100 is rotated by 90 degrees, The pin 141 is brought into a horizontal state and the contact with the female terminal 23 is made so that the line-type lighting apparatus 100 can be easily turned on.

In the line-type lighting apparatus 100 in such a state, the female terminal 23 elastically supports the terminal pin 141, so that the line-type lighting apparatus 100 is not separated from the socket 20.

The connection unit 113 is disposed at one end of the circuit board 111 to electrically connect the circuit board 111 and the power source unit and fix the light source unit 110 (circuit board 111) to the end cap 130 do.

The end cap 130 shields the opening of the optical housing 120 and accommodates the connection portion 113 of the light source unit 110. The end cap 130 is preferably made of a resin material of insulating material to prevent a short circuit.

The end cap 130 may have a cylindrical structure in which one side is open and the other side is closed. For example, it may include at least a plate 131 that shields the opening of the optical housing 120 and an outer wall 133 that extends from the rim of the plate 131 and defines a space therein.

The plate 131 has a shape and a size corresponding to the openings of the optical housing 120. In the embodiment, the plate 131 has an approximate circular shape.

The plate 131 fixes the power source unit. Specifically, the plate 131 is fixed through the terminal pin 141 described later. One end of the terminal pin 141 is exposed to the outside of the end cap 130 and the other end of the terminal pin 141 is positioned inside the end cap 130.
