Description

[0001] LENS, LIGHT EMITTING DEVICE PACKAGE, AND LIGHT SOURCE DEVICE FOR ELECTRONIC DEVICE [0002]

The present invention relates to a lens, a light emitting device package, and a light source device for an electronic device, and more particularly to a lens, a light emitting device package, and a light source device for an electronic device that can be applied to various electronic devices such as a light source of an infrared will be.

Conventionally, a lens made of a translucent material of various shapes has been widely used to control the path of light generated in various light emitting devices such as LEDs.

For example, a structure having a flange on an upper surface of a lens for assembling a lens and a package body, as shown in Patent Publication No. 20120066455 (the name of the invention: a light emitting diode package for a flash) It is a commonly used method for assembly of LENS and has been widely used. This structure can be used very easily to improve the assembly while maintaining the efficiency of the lens. However, it is not easy to assemble a small size package and lens. Since the flange is formed in the lower part of the outermost part of the TIR lens and the supporting part for supporting the flange is formed to be as high as the flange part of the lens, the size of the package becomes large or it is difficult to actualize the package.

On the other hand, in general, the larger the size of the lens, the easier it is to control the optical properties such as the amount of light condensed. Conversely, LEDs are becoming increasingly smaller and more so in the case of LEDs mounted on mobile devices such as mobile phones rather than large systems such as TVs.

In general, the package size is decreasing. In order to maximize the light generated by the LED, it is difficult to make the lens as large as possible but not to exceed the size of the package. To overcome this problem, it is advantageous to reduce or eliminate the flange located at the top of the lens.

On the other hand, as disclosed in Patent Publication No. 20120111174 (entitled Eccentric Focusing Lens for Light Emitting Device and Lighting Apparatus Using the Same), it is difficult to control the curvature of the lens for light control, This may reduce the reliability and uniformity of the product.

However, in such a conventional lens, if the size of the flange is reduced or eliminated, it is difficult to control the light path, and there is a limit to controlling the light to be deflected.

Conventionally, a conventional lens uses a cylindrical pin. When a pin is aligned with a pinhole precisely in alignment, a pin is inserted into the pinhole. Therefore, a high precision is required, for example, Therefore, there is a problem that the aligning operation is troublesome and the contact area with the package is not wide, so that the alignment position is easily changed due to processing defects or wear of the pin or pin hole.

First, as shown in FIGS. 1 to 5, a lens 100 according to some embodiments of the present invention may include a main body 10 and a guide portion 11.

Here, the body 10 may be a monolithic structure of a translucent material, in which a light-incident portion 10a is formed on one side and a light-emitting portion 10b is formed on the other side.

More specifically, as shown in FIGS. 1 to 5, the light emitting portion 10b of the body 10 has a light emitting portion 10a on the mounting surface of the light emitting portion 10a so that the light emitting axis can be deflected in one direction And a first prism inclined surface portion C-1 inclined at a first deflection angle K1.

The first prism inclined surface portion C-1 deflects the optical path in one direction. When the light passes through the boundary surface between the medium and the medium, as in the prism principle, .

At this time, the angle of refraction according to the traveling direction may vary depending on the properties of the medium, and may vary depending on the optical characteristics of the body 10, for example.

Therefore, the first deflection angle K1 can be designed optimally according to the material of the body 10, the refractive index, the shape, and the optical characteristics.

For example, when the body 10 is made of glass, the refractive index is 1.45 to 1.96. In order to increase the refractive index, lead or bar can be added, and iron can be added to make the refractive index small.

In addition, the body 10 may be made of at least one of EMC, epoxy resin composition, silicone resin composition, modified epoxy resin composition, modified silicone resin composition, polyimide resin composition, modified polyimide resin composition, (PPA), polycarbonate resin, polyphenylene sulfide (PPS), liquid crystal polymer (LCP), ABS resin, phenol resin, acrylic resin, PBT resin and the like.

In addition, the body 10 may be formed of a polycarbonate series, a polysulfone series, a polyacrylate series, a polystyrene series, a polyvinyl chloride series, a polyvinyl alcohol series, a polynorbornene series, a polyester, A translucent resin-based material can be applied.

In order to improve the light dispersibility, a scattering pattern, a scattering member, or the like may be provided by various methods such as forming fine patterns, fine protrusions, diffusion films, or the like on the surface or inside of the body 10 .

Here, the light-emitting axis may refer to a directional axis toward a path through which the largest amount of light among the light distribution distributions of the light emitted through the emitting portion 10b of the body 10 passes.

The receiving space A serves to allow the light emitting device 20 to be wholly or partly inserted into the light incident portion 10a to maximize the light incident area. For example, as shown in FIGS. 1 to 5 The receiving space A may be formed in such a manner that the light path diverging in all directions in the light emitting element 20 can be refracted upward so as to be primarily in the vertical upward direction A downwardly convex convex lens portion 10c may be formed above the accommodation space A.

However, the shape of the accommodation space A is not limited to the drawings, but can be applied to a variety of shapes such as a dome shape, a conical shape, a box shape, a polygonal cone shape, and various geometric shapes.

1 to 5, the body 10 is formed with a spherical spherical surface 10d partially convex partially between the light-incident portion 10a and the light-emitting portion 10b, The front side surface 10-1, the rear side surface 10-2, the left side surface 10-3 and the right side surface 10-4 may be respectively formed in a vertically flat shape.

The rounded spherical surface 10d, the front side surface 10-1, the rear side surface 10-2, the left side surface 10-3 and the right side surface 10-4 are made to use total internal reflection And can act to reflect the ambient light obliquely introduced into the body 10 upwardly and actively reflect the light emitted from the light emitting element 10d with a small size using the rounded spherical surface 10d and the above- 20 can be emitted in a larger area.

5, the path of the light emitted from the light emitting device 20 is a path extending in the front-rear, left-right, and upward directions. A part of the light emitted from the light emitting device 20 may be introduced into the body 10 through the light entering portion 10a of the body 10. [

At this time, the light passing through the convex lens portion 10c formed above the accommodation space A of the light-incident portion 10a is refracted and the optical path can be transformed close to the vertical upward direction.

The other part of the light emitted from the light emitting device 20 is totally diagonally reflected on the spherical spherical surface 10d through the light-incident portion 10a so that the optical path can be also changed in the vertical direction .

Another part of the light emitted from the light emitting element 20 passes through the light input part 10a and is reflected by the front side face 10-1, the rear side face 10-2, (10-3) and the right side (10-4), respectively, so that the optical path can be also converted to a vertical upward direction.

As described above, the light passing through the inside of the body 10, whose optical path is converted to a vertical upward direction, is emitted to the outside through the light emitting portion 10a of the body 10, It can be guided to be deflected in one direction by the prism inclined surface portion C-1.

Therefore, light control can be easily performed by using the prism inclined surface of the light-exiting portion, and the size of the lens can be made compact in accordance with a small light emitting element, thereby making it easily applicable to various electronic devices such as mobile phones, smart phones, .

1 to 5, the guide part 11 is formed so that the light incidence part 10a can be aligned in a predetermined position when assembled with the reflection member 40 of the light emitting device package 1000. [ The guiding portion 11 is formed to extend radially toward the light incidence portion 10a and has guide slopes 11a formed on both sides thereof. It can be four radial wing legs.

Here, the guide portion 11 may be any elongated wing-shaped bridge that is equally arranged in a radial shape such as at least two, three, five, six, or more.

Further, a vertically close boundary portion may be formed between the first prism inclined plane portion C-1 and the second prism inclined plane portion C-2. That is, it may be a shape in which the mountain and the bone are repeated due to the boundary portion. Here, the second deflection angle K2 may be different from the first deflection angle K1.

The structure and the role of the body and the guide portion 11 may be the same as those described in Figs. 1 to 5. Therefore, detailed description is omitted.

Further, the light emitting portion may be a plane parallel to the mounting surface of the light-incoming portion so as to guide the light in the vertical direction.

1, the light emitting device package 100 according to some embodiments of the present invention includes a light emitting device 20, a substrate 30, a reflective member 40, and a lens 100 ).

Here, as shown in FIGS. 1 and 4, the light emitting device 20 may be an infrared LED that emits infrared light.

In addition, the light emitting device 20 may be a light emitting diode (LED) in the form of a flip chip having a first pad and a second pad.

The light emitting device 20 may be formed of a semiconductor. For example, LEDs of blue, green, red, and yellow light emission, LEDs of ultraviolet light emission, and LEDs of infrared light emission, which are made of a nitride semiconductor, can be applied.

The light emitting device 20 can be formed by epitaxially growing nitride semiconductors such as InN, AlN, InGaN, AlGaN, and InGaAlN on a sapphire substrate for growth or a silicon carbide substrate by a vapor phase growth method such as MOCVD To grow. The light emitting device 20 may be formed using semiconductors such as ZnO, ZnS, ZnSe, SiC, GaP, GaAlAs, and AlInGaP in addition to the nitride semiconductor. These semiconductors can be stacked in the order of an n-type semiconductor layer, a light emitting layer, and a p-type semiconductor layer. The light emitting layer (active layer) may be a laminated semiconductor having a multiple quantum well structure or a single quantum well structure or a laminated semiconductor having a double hetero structure. In addition, the light emitting device 20 can be selected to have an arbitrary wavelength depending on the application such as display use and illumination use.

Here, as the growth substrate, an insulating, conductive or semiconductor substrate may be used if necessary. For example, the growth substrate may be sapphire, SiC, Si, MgAl ₂ O ₄ , MgO, LiAlO ₂ , LiGaO ₂ , GaN. A GaN substrate, which is a homogeneous substrate, is preferable for epitaxial growth of a GaN material, but a GaN substrate has a problem of high production cost due to its difficulty in manufacturing.

Sapphire and silicon carbide (SiC) substrates are mainly used as the different substrates. Sapphire substrates are more utilized than expensive silicon carbide substrates. When using a heterogeneous substrate, defects such as dislocation are increased due to the difference in lattice constant between the substrate material and the thin film material. Also, due to the difference in the thermal expansion coefficient between the substrate material and the thin film material, warping occurs at a temperature change, and warping causes a crack in the thin film. This problem may be reduced by using a buffer layer between the substrate and the GaN-based light emitting laminate.

In addition, the substrate for growth may be completely or partially removed or patterned in order to improve the optical or electrical characteristics of the LED chip before or after the growth of the LED structure.

For example, in the case of a sapphire substrate, the substrate can be separated by irradiating the laser to the interface with the semiconductor layer through the substrate, and the silicon or silicon carbide substrate can be removed by a method such as polishing / etching.

Another supporting substrate may be used for removing the growth substrate. In order to improve the light efficiency of the LED chip on the opposite side of the growth substrate, the supporting substrate may be bonded using a reflective metal, As shown in FIG.

In addition, patterning of the growth substrate may improve the light extraction efficiency by forming irregularities or prism inclined surfaces on the main surface (front surface or both surfaces) or side surfaces of the substrate before or after the LED structure growth. The size of the pattern can be selected from the range of 5 nm to 500 μm and it is possible to make a structure for improving the light extraction efficiency with a rule or an irregular pattern. Various shapes such as a shape, a column, a mountain, a hemisphere, and a polygon can be adopted.

In the case of the sapphire substrate, the crystals having a hexagonal-rhombo-cubic (Hexa-Rhombo R3c) symmetry have lattice constants of 13.001 and 4.758 in the c-axis direction and the a-axis direction, respectively, and have C plane, A plane and R plane. In this case, the C-plane is relatively easy to grow the nitride film, and is stable at high temperature, and thus is mainly used as a substrate for nitride growth.

Another material of the growth substrate is a Si substrate, which is more suitable for large-scale curing and relatively low in cost, so that mass productivity can be improved.

In addition, since the silicon (Si) substrate absorbs light generated from the GaN-based semiconductor and the external quantum efficiency of the light emitting device is lowered, the substrate may be removed as necessary, and Si, Ge, SiAl, A support substrate such as a metal substrate is further formed and used.

When a GaN thin film is grown on a different substrate such as the Si substrate, the dislocation density increases due to the lattice constant mismatch between the substrate material and the thin film material, and cracks and warpage Lt; / RTI > The buffer layer may be disposed between the growth substrate and the light emitting stack for the purpose of preventing dislocation and cracking of the light emitting stack. The buffer layer also functions to reduce the scattering of the wavelength of the wafer by adjusting the degree of warping of the substrate during the growth of the active layer.

Further, although not shown, the light emitting element 20 may be a flip chip type having a signal transmission medium such as a pump or a solder in addition to the pad. In addition, a bonding wire may be applied to the terminal, A light emitting element to which a bonding wire is applied to only the second terminal, a horizontal type, a vertical type light emitting element, or the like can be applied.
