Description

LIGHTING DEVICE

An embodiment relates to a lighting device.

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.

However, the illumination provided with the light emitting diode has a problem that it is recognized as a point light source from the outside due to the strong directivity of the light emitting diode.

 In addition, in a line-shaped lighting device for substituting general fluorescences, a guide is required to fix the light source unit inside the cylindrical optical housing.

In addition, a structure for covering both ends of the optical housing and for coupling the end cap and the optical housing in which the terminal pins are formed is also required.

In addition, a separate structure is required for alignment of the end cap and the optical housing.

Therefore, in the conventional line-shaped illumination device, the optical housing is formed by injection molding, and the above-described configuration is added to the optical housing.

This poses a problem that the manufacturing method is complicated and the manufacturing cost is increased.

Embodiments provide a lighting apparatus that is simple in manufacturing and allows the light source unit to be easily coupled to an optical housing.

An illumination apparatus according to an embodiment includes a light source unit including a plurality of point light sources and a circuit board on which the point light sources are disposed, a cylindrical optical unit having the support unit for receiving the light source unit therein, The circuit board includes a body, an electrode pattern formed on one side of the body and electrically connected to the point light source, a heat dissipating unit disposed on the other side of the body to radiate heat of the circuit board, And a gap supporter for maintaining a distance between the other surface and the inner surface of the optical housing.

The embodiment provides the advantage that not only the guide supports the circuit board but also the position where the fastening member penetrating the end cap is engaged so that the guide is used versatile and can reduce the number of components, exist.

Further, the guide of the embodiment is integrally formed on the inner surface of the optical housing, so that there is an advantage that it can be easily manufactured integrally in the injection molding process of the optical housing.

In addition, the embodiment has the advantage that the manufacturing cost is reduced by a multi-purpose guide and the configuration of the lighting apparatus is simplified.

Further, since the guide of the embodiment forms a space into which the fastening member is inserted, there is an advantage that a space for fastening the fastening member is not required separately.

The lighting apparatus 100 according to an embodiment of the present invention includes a light source unit 110 having a circuit board 111 on which a plurality of point light sources 112 and point light sources 112 are positioned, A power source unit 160 for supplying operating power, a light source unit 110 and a power source unit 160 housed in the power source unit 160, An optical housing 120 in which a light diffusion space 125a in which the generated light is diffused and a power supply space 125b in which the power supply unit 160 is placed is divided into an optical housing 120 in which both ends in the width direction of the circuit board 111 are slidably coupled An end cap for shielding the opening of the optical housing 120 and a fastening member 180 for fastening the end cap 130 to the optical housing 120. [

1 to 3, the light source unit 110 generates light. The light source unit 110 may include a plurality of point light sources 112.

The plurality of point light sources 112 may be arranged with a constant pitch for supplying uniform light to the lighting apparatus 100. [ The plurality of point light sources 112 can be set in pitch and number in consideration of the luminous intensity of the illuminating device 100.

In addition, the plurality of point light sources 112 may be white in color, or the colors of adjacent point light sources 112 may be mixed to emit white light.

The point light source 112 includes a self-emitting element such as a light emitting element (diode) or a laser diode (LD).

The light source unit 110 may have various structures for generating light, but includes, for example, a circuit board 111 on which the point light source 112 and the point light source 112 are located.

The circuit board 111 supports the point light source 112 and is electrically connected to the point light source 112 to supply power to the point light source 112.

The circuit board 111 may include a connector 113 electrically connected to the power source unit 160.

A plurality of heat radiation patterns 115 for radiating heat transferred to the circuit board 111 may be formed on one surface of the circuit board 111.

The heat radiating pattern 115 radiates heat of the circuit board 111.

The heat radiation pattern 115 may be made of a metal material having excellent thermal conductivity. Preferably, when the point light source 112 (light emitting element) is mounted on one surface of the circuit board 111 by surface mounter technology (SMT), the heat radiation pattern 115 is also surface- (Lead, Pb).

When the radiation pattern 115 is formed of solder, there is an advantage that a separate process is not necessary since the radiation pattern 115 can be operated simultaneously with the mounting of the point light source 112.

Specifically, a plurality of heat radiation patterns 115 may be disposed on one side or the other side of the circuit board 111 at a predetermined pitch along the longitudinal direction of the circuit board 111.

For example, the heat radiation pattern 115 may include a metal or a resin material having excellent thermal conductivity. Preferably, the heat radiation pattern 115 may be formed of aluminum.

The power source unit 160 supplies operating power to the light source unit 110.

The power supply unit 160 supplies driving power to each component constituting the lighting apparatus 100.

For example, the power source unit 160 receives an AC power of 110V to 220V, and can supply DC power of any one of 25V, 50V, and 100V to the light source unit 110 using the AC power.

Also, the power source unit 160 can supply DC power of 3 V to the communication module (not shown) using the inputted AC power.

For example, the power supply unit 160 includes a power supply unit 163 for converting power and a power supply circuit board 161 on which the power supply unit 163 is located.

The power supply circuit board 161 of the power supply unit 160 may be provided with a power supply connector 165. The power connector 165 is electrically connected to the terminal pin 141.

The power supply unit 160 may include a spacer 167 which is supported by the circuit board 111 and maintains a spacing distance.

Specifically, the spacer 167 is located on one side of the power supply circuit board 161 of the power supply unit 160. [ Then, the spacer is supported on the other surface of the circuit board 111.

1 to 3, the optical housing 120 protects the light source unit 110 from external shocks, moisture, and the like, supports the light source unit 110, and guides the light generated by the light source unit 110 And diffuses the light generated by the light source unit 110.

The optical housing 120 accommodates the light source unit 110 therein and may have openings 125a and 125b at least at one end thereof.

For example, the optical housing 120 may have a shape in which both end portions in the longitudinal direction are opened and have an empty space therein. Specifically, the optical housing 120 may be tubular or cylindrical in the longitudinal direction as in Fig.

The optical housing 120 is accommodated in the light source unit 110 and the power source unit 160 through openings 125a and 125b at both ends.

More specifically, the openings 125a and 125b of the optical housing 120 include a light diffusion space 125a through which the light generated by the point light source 112 is diffused around the circuit board 111, And a power supply space 125b to be positioned.

That is, the openings 125a and 125b of the optical housing 120 are divided into the light diffusion space 125a and the power source space 125b by sliding the circuit board 111 of the light source unit 110 in the longitudinal direction .

The optical housing 120 may have an integral or detachable structure. In the embodiment, the optical housing 120 is integrally formed and can be formed by an injection molding method.

3, the optical housing 120 includes a front portion 121 for diffusing light generated from the point light source 112 in the circuit board 111 and a front portion 121 for diffusing light generated from the point light source 112, 125b and a rear portion 123 surrounding the power supply unit 160. [

The front portion 121 covers one area S1 of the optical housing 120. [

The front portion 121 diffuses the light generated by the point light source 112 and protects the light source unit 110 accommodated therein.

The shape of the front portion 121 is not limited, but the front portion 121 may have a predetermined distance from the point light source 112, and may have a fan shape on the optical axis, which is the main path along which light generated by the point light source 112 travels. Is preferable in terms of diffusion of light.

Specifically, the front portion 121 forms a partial area of the optical housing 120, and a cylindrical portion (semicircular) can be formed in the longitudinal direction.

Particularly, the front portion 121 forms the light diffusion spaces 125a and 125a together with the circuit board 111 of the light source unit 110. FIG.

The front portion 121 may include diffusion particles to prevent glare of light generated by the point light source 112 of the light source unit 110 and uniformly emit light to the outside,

A prism pattern or the like may be formed on at least one of the inner surface and the outer surface of the front portion 121.

Further, the phosphor may be applied to at least one of the inner surface and the outer surface of the front portion 121.

Since the light generated from the light source unit 110 is emitted to the outside through the front part 121, the front part 121 should have a good light transmittance and have sufficient heat resistance to withstand the heat generated by the light source unit 110 .

Therefore, the front portion 121 is preferably made of a material including polyethylene terephthalate (PET), polycarbonate (PC), or polymethyl methacrylate (PMMA).

The rear portion 123 provides a space in which the power unit 160 is located.

For example, the rear part 123 forms another partial area S2 of the optical housing 120 and has a semi-circular shape in the longitudinal direction, so that a cylindrical housing together with the front part 121 can be formed .

The rear portion 123 forms a power supply space 125b in which the power supply unit 160 is located together with the circuit board 111 of the light source unit 110. [

When the optical housing 120 is formed long in the longitudinal direction, a rib 124 may further be formed on the rear portion 123 to reinforce the rigidity of the optical housing 120.

Specifically, the rib 124 may be formed to be long in the longitudinal direction of the optical housing 120 in the rear portion 123. In particular, the rib 124 may be positioned inside the rear portion 123 in consideration of the user's aesthetics.

FIG. 4 is a side view of an end cap according to an embodiment of the present invention, and FIG. 5 is a cross-sectional perspective view illustrating a combined state of an end cap and an optical housing according to an embodiment of the present invention.

4 and 5, the end cap 130 shields the openings 125a and 125b of the optical housing 120. As shown in FIG.

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. A plate 131 that corresponds to the openings 125a and 125b of the optical housing 120 and to which the terminal pins 141 are fixed, And a cylinder 133 extending from the rim of the plate 131 to form a space therein.

One end of the terminal pin 141 is exposed through the end cap 130 and the other end is positioned inside the end cap 130. The external terminal of the terminal pin 141 is electrically connected to the external power source and the internal terminal of the terminal pin 141 is electrically connected to the power source unit 160.

Specifically, the terminal pin 141 is energized with the power supply unit 160 by the cable 152 and the terminal connector 152.

The terminal pin 141 has a size and an arrangement that can be inserted into a standardized socket. Preferably, the terminal pins 141, 141a and 141b may include at least two terminals. The two terminal pins 141 may be supplied with power of the same polarity, may be supplied with a power of another polarity, and either one of the two terminal pins 141 may be an insulator.

The plate 131 is fixed through the terminal pin 141. 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.

The plate 131 has a size and shape corresponding to the openings 125a and 125b of the optical housing 120. [ The plate 131 is formed with a fastening hole 132 through which the fastening member 180 passes.

Specifically, the fastening hole 132 is formed to correspond to the guide 170 so that the fastening member 180 can be coupled to the guide 170 through the fastening hole 132.

The cylinder 133 extends from the rim of the plate 131, and the cylinder 133 is formed in a cylindrical shape and is formed to correspond to the optical housing 120.

The cylinder 133 is engaged with the openings 125a and 125b of the optical housing 120.

For example, the cylinder 133 is divided into an exposed region 133a and an interpolation region 133b.

The interpolation area 133b is an area to be interpolated into the openings 125a and 125b of the optical housing 120. [ Specifically, the interpolation area 133b may have a step with the exposed area 133a.

The exposed area 133a is exposed without being inserted into the openings 125a and 125b of the optical housing 120 and is located on the same plane as the outer surface of the optical housing 120 for the aesthetic sense.

At this time, an alignment groove 135 into which the guide 170 is inserted is formed in the interpolation area 133b.

The alignment groove 135 is formed by recessing the interpolation region 133b in the longitudinal direction so that the guide 170 is positioned inside.

One end of the guide 170 in the longitudinal direction is inserted into the alignment groove 135.

Of course, the present invention is not limited to this, and the end cap 130 may be formed with one longitudinal end of the guide 170 to fix the position thereof.

The guide 170 fixes the circuit board 111 in the optical housing 120 and provides a space in which the circuit board 111 slides.

Further, the guide 170 provides a space in which the fastening member 180 passing through the end cap 130 is engaged.

The guide 170 also aligns the end cap 130 when the end cap 130 is coupled to the optical housing 120.

Since the optical housing 120 is elongated in the tube shape, the light source unit 110 is inserted in the longitudinal direction through the openings 125a and 125b of the optical housing 120 and is coupled.

Therefore, both ends of the circuit board 111 in the width direction are slidably coupled to the guide 170 in the longitudinal direction.

For example, the guide 170 is formed by extending in the longitudinal direction from the inner circumferential surface of the optical housing 120 so that both ends of the circuit board 111 in the width direction are inserted while the circuit board 111 is slid in the longitudinal direction.

Preferably, the guides 170 are provided in pairs in the optical housing 120 so as to face each other, and can be positioned adjacent to the boundary between the front portion 121 and the rear portion 123. [

Specifically, the guide 170 includes a first support portion 171 and a second support portion 173.

The first support portion 171 supports one surface of the circuit board 111 where the point light source 112 is located. In addition, the first supporting portion 171 can press one surface of the circuit board 111 in the other surface direction.

The second supporting portion 173 supports the other surface opposite to the one surface of the circuit board 111. Further, the second supporting portion 173 can press the other surface of the circuit board 111 in the one surface direction.

That is, the first support portion 171 has an elastic restoring force in the direction of the second support portion 173, and the second support portion 173 has an elastic restoring force in the direction of the first support portion 171.

The first support portion 171 and the second support portion 173 define a space in which the fastening member 180 is inserted in the longitudinal direction.

3, a space may be formed between the first support portion 171 and the second support portion 173 to allow the circuit board 111 and the fastening member 180 to be inserted.

More specifically, since the length of the guide 170 is longer than the length of the circuit board 111, the circuit board 111 is inserted into the guide 170, and the fastening member 180 is inserted into the spaces at both ends of the remaining guide 170 A space for insertion can be formed.

That is, the first support portion 171 and the second support portion 173 define a space in which the fastening member 180 is inserted in the longitudinal direction.

The guide 170 supports not only the circuit board 111 but also the position where the fastening member 180 passing through the end cap 130 is engaged and aligns the end cap 130 .

As a result, the multi-purpose guide 170 reduces manufacturing costs and simplifies the structure of the lighting apparatus.

One end of the first supporting portion 171 and one end of the second supporting portion 173 may be connected to each other by a connecting portion 172 and the connecting portion 172 may be located on the inner surface of the optical housing 120.

In order to facilitate insertion of the fastening member 180, the first support portion 171 may have a round shape with one side open on the cross section together with the second support portion 173. [ Here, the circuit board 111 may be inserted into the open side, and a screw groove may be formed in the circular shape.

The guide 170 may further include a power supporter 175 extending from the second support portion 173 toward the power source unit 160 to separate the circuit board 111 from the power source unit 160.

The power supply support unit 175 supports the power supply circuit board 161 of the power supply unit 160 to fix the power supply unit 160. [

Also, the power supply support part 175 separates the power supply unit 160 from the circuit board 111 to prevent electrical short circuit.

Of course, this guide 170 is formed integrally with the optical housing 120 by the injection molding method. The shape of the guide 170 of the present invention has a shape that can be easily injection-molded long in the longitudinal direction, and can be used for many purposes in a simple form.

6 is an explanatory view showing a state in which a fastening member 180 is inserted into a guide 170 according to an embodiment of the present invention.

Referring to FIG. 6, the fastening member 180 fastens the end cap 130 to the optical housing 120.

The fastening member 180 is inserted through the fastening hole 132 formed in the plate 131 and inserted into the guide 170.

6, the length of the guide 170 is longer than the length of the circuit board 111 so that the circuit board 111 is inserted into the guide 170 and the space between both ends of the remaining guide 170 The fastening member 180 is inserted.

Therefore, there is an advantage that a space for coupling the fastening member 180 does not need to be separately manufactured. The fastening member 180 may be a bolt or the like.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be taken by way of illustration, It can be seen that various modifications and applications are possible. For example, each component specifically shown in the embodiments can be modified and implemented. It is to be understood that all changes and modifications that come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
