As shown in FIGS. 1 and 2, the linear light emitting device 140 realizes a light emitting configuration in which the light emitting surface has a structure that is closer to the starting light than the surface emitting light, and the width (x) (y) is longer than that of the light emitting device.

Specifically, the linear light emitting module may include a lower terminal spaced apart from an upper terminal and the upper terminal, and a power terminal extending downward from the lower terminal to be connected to a power terminal of the socket, And at least one pair of linear light emitting elements in which a lead portion at one end and a lead portion at the other end are electrically coupled to each other. (Fig. 5 is a plan view showing the structure of this linear light emitting module, which will be described later.) Fig.

FIG. 3 is a view showing a mounting structure of the light emitting main unit 130 shown in FIG. 1 and FIG. 2 and the above-described linear light emitting module. 4 is an exploded view of Fig.

3 and 4, the linear light emitting module includes a lower terminal 153 spaced apart from the upper terminal 152 and the upper terminal, a lower terminal 153 extending downward from the lower terminal 154, And a linear light emitting element 140 electrically coupled to one end of the lead terminal and the other end of the lead terminal are electrically connected to the upper terminal 152 and the lower terminal. .

The light guide plate 130 has a bar type body 131 having one end coupled to the seating portion and the other end protruding into the accommodation space. The light guide plate 130 has a body portion 131 having a width larger than the width of the body portion. And a second engaging part 133 formed at an upper region of the body part so as to be wider than the width of the body part so that the upper terminal is engaged with the outer surface of the body part .

The upper terminal 152 may be arranged to contact the side surface of the second engaging part 133 of the light guide main part 130. More preferably, Can be combined into a partially inserted structure.

The upper terminal according to the embodiment of the present invention can be implemented as a ring in an integrated structure.

As shown in FIG. 4, the lower terminals 153 may be formed in a structure in which a pair of lower terminals are disposed at mutually opposite positions. Hereinafter, the first lower terminal 153 and the second lower terminal 163 will be described. The first lower terminal 153 and the second lower terminal 163 correspond to the upper terminal 152 and a plurality of linear light emitting devices 140 may be disposed between the spaced apart spaces, And can be realized as a linear light emitting module.

The first lower terminal 153 and the second lower terminal 163 may be attached to a region of the main body 131 of the light guide 130.

Specifically, a first engaging portion 132, which is formed to be wider than a width of the body portion in one region of the body portion, and which binds the lower terminal 153 to an outer surface of the body portion, And a second coupling portion 133 is formed on the light guide main portion 130 for coupling the upper terminal 152 to the outer surface.

For example, when the area of the first coupler 132 is wider than that of the second coupler 133 as in the structure of FIG. 1, the linear light emitting device naturally tilts at a certain angle. When the linear light emitting device is disposed at the angle shown in FIG. 1, the emitted light has the advantage that the light output amount increases in the downward direction.

In addition, in the embodiment of the present invention, the light-emitting peripheral portion 130 may be formed of a material having the same material as the material of the body portion and the first and second coupling portions. Further, .

It is also possible to use a material selected from the group consisting of polystyrene, polycarbonate, polystyrene, polyolefin, cellulose acetate and polyvinyl chloride. This makes it possible to increase the light utilization efficiency by reflecting or transmitting the light emitted from the arrangement structure of the above-described linear light emitting elements from the inside again.

Particularly, in the present invention, such a linear light emitting device 140 can be disposed in the inner accommodating space of the bulb portion 110 in FIG. 1, and a special terminal structure for supporting the linear light emitting device 140 can be realized.

As an example of the structure of the linear light emitting device 140, the substrate may be a copper or copper alloy substrate, or an Ag plating layer may be formed on such a substrate.

For example, in the case of a plurality of LED chips mounted on the substrate, 20 to 40 LED chips may be mounted based on the length of the substrate excluding the lead portions 142 and 142 from 30 mm to 33 mm, Layer can be applied to form a thin bar-type structure.

The above-mentioned phosphor is a fluorescent resin composition containing a curable resin and a phosphor, and has a wavelength converting function. For example, a yellow phosphor capable of converting blue light into yellow light, a red phosphor capable of converting blue light into red light Phosphors and the like. Examples of the yellow phosphor include garnet-type crystal structures such as Y 3 Al 5 O 12 : Ce (YAG (yttrium aluminum garnet): Ce) and Tb 3 Al 3 O 12 : Ce (TAG (terbium aluminum garnet) And oxynitride phosphors such as Ca-alpha-SiAlON. As the red phosphor, for example, a nitride phosphor such as CaAlSiN 3 : Eu 2 CaSiN 2 : Eu and the like can be applied.

In another embodiment of the present invention, the light-emitting main body 130 includes a bar-type body part 131 having one end coupled to the seating part and the other end projecting into the accommodation space, A first coupling part 132 which is formed to be wider than the width of the body part and which binds the lower terminal to the outer surface, and a second coupling part 132 which is wider than the width of the body part in the upper region of the body part, And a second coupling portion 133.
