The transparent cover 53 can reduce leakage and loss of light emitted through the light emitting surface S1. The transparent portion R1 extends from the top of the lighting module 200 to the top of the recess R1. The cover 530 can be made of a transparent material such as PC, OPS, PMMA, PVC, etc. The transparent cover 530 can tightly mount the lighting module 200 on the support 511. A part of the transparent cover 530 may be attached or pressed against the housing 50. The outer wall 520 of the nozzle 10 is disposed on a stepped portion 524, which is The upper surface of the step portion 524 is disposed around the upper portion of the recess R1. The transparent cover 530 is disposed on the same straight line as the upper surface of the illumination module 200, and the lower surface of the transparent cover 530 is disposed on the same straight line as the upper surface of the illumination module 200. The lower surface of the lighting module 200 is supported by the support portion 511. The adhesive layer is made of a transparent material such as UV adhesive, silicone or epoxy.

A protrusion is provided on a part of the transparent cover 530 to be engaged with a groove 525 on the outer wall 521 on the side of the storage section R2. The present invention may include, but is not limited to, a start 533.

[0040] The transparent cover 530 is disposed in a plane perpendicular to the light output surface S1 of the lighting module 200. Therefore, the surface light emitted through the light emitting surface S1 of the lighting module 200 is incident on the and can be diffused or refracted in other directions.

[0041] The transparent cover 530 has a coating layer disposed on the upper and / or lower surface thereof for blocking light. Alternatively, light can be emitted through an open area OP2 corresponding to the upper portion of the recess R1. As shown in FIG. 5, when a light blocking member 540 is disposed on a transparent cover 530, The transparent cover 530 is made of a material that transmits light or can diffuse light. The bar 530 may have a rough surface and be treated to prevent hot spots from being visible from the outside. 6 and 7, the light blocking member 540 can be exposed to the transparent The light emitted through the cover 530 is emitted, and the light emitted through the opening OP1 is , can function as an indicator. The indicator can include at least one Alternatively, a plurality of the inclusions may be arranged, and when a plurality of inclusions are arranged, they may be the same or different from each other. The indicator shall be at least one of the following: logo, icon, symbol, or identifying mark shape. The indicators can be described with reference to FIG. I will explain this in detail.

[0042] As shown in FIGS. 4 and 8, the lighting module 200 has a light emitting direction (e.g., , X), the lengths D2 and D3 may be different. The minimum length D3 in one direction (e.g., X) may be smaller than the length D1 of the second side surface Sb1. The length may be 50% or less of the maximum length D1 of the transparent cover 530. (e.g., X) the maximum length D2 is 50% greater than the maximum length D1 of the transparent cover 530. The maximum length of the transparent cover 530 is It may be the same as the optical axis direction in which the central luminous intensity is highest.

[0043] The lengths D2 and D3 of the lighting module 200 in one direction are the longest on the driver's side and the longest on the object side. Therefore, the light exit surface S1 of the lighting module 200 may be located at the first side. The area adjacent to the surface Sa1 is inclined at a predetermined angle Q3 from the area adjacent to the second side surface Sb1. The angle Q3 is determined by the horizontal imaginary line and the extension line L of the inclined light output surface S1. The angle between b is 60 degrees or less, for example, 10 degrees to 60 degrees or 20 degrees to 50 degrees. If the thickness is greater than the range, the area of ​​the recess R1 is reduced. If the difference is small, a difference in the amount of reflected light may occur. The first region Ra is formed so as to reflect incident light in the vertical direction as shown in FIG. 12(A). The second region Rb is surface-treated, and the second region Rb is displayed so as to reflect the light in the region set as shown in FIG. 12(B). For example, in the first region Ra that overlaps with the opening OP1 in the vertical direction, It is possible to reflect light in a direction directly above. In addition, the opening OP1 does not overlap with the opening OP1 in the vertical direction. In the second region Rb, which partially overlaps the opening OP1, the opening OP1 faces the driver's side. As a result, the light emitted through the opening OP1 can be reflected. The brightness reduction can be suppressed, and light with a higher brightness value is provided to the driver. Therefore, the driver can see the indicator more effectively. can be done.

[0044] In addition, the light emitting device 100 is rotated at a predetermined angle Q5 The tilt angle Q5 is 60 degrees or less, for example, 10 degrees to 60 degrees. The tilt angle can be in the range of 20 to 50 degrees. The light emitted through the reflector 50 is emitted with the highest luminous intensity toward the second region Rb. The light reflected by the second region Rb of 10 will be seen with the highest luminance value in the direction of the driver. .

[0045] As shown in FIG. 9, the light emitting element 100 is tilted and arranged on the substrate of the lighting module 200. The directional angle R10 of the light emitted from the tilted light emitting element 100 is 100 degrees or more. For example, the angle may be in the range of 105 degrees to 140 degrees. The other components 105 are arranged in an area outside the beam angle R10. Taking into consideration the directional characteristics of the element, the component 105 is placed in an area that does not interfere with the light emitted from the light emitting element. This is because the lower surface of the substrate 210 is disposed in close contact with the support portion 511 of the housing 500. Therefore, components cannot be placed on the bottom surface of the board, and the light directivity angle R10 is set to the top of the board 210. The component 105 can be placed in the designated area.

[0046] As shown in FIG. 10, a transparent cover 530 is disposed on the top of the housing 500. The transparent cover 530 is also disposed with a long length in the direction from the first outer surface S21 to the second outer surface S22.

The housing 500 is arranged at a distance of 0.8 cm to 1.5 cm. The size of the housing 500 is not limited to a specific size. It can be changed depending on the object being illuminated.

[0047] As shown in FIG. 13, a light blocking member 54 is provided on the transparent cover 530 and the upper surface of the housing 500. The light blocking member 540 is disposed on the housing 500 of the optical assembly 501. The indicator may be attached to a surface or a rearview mirror. , formed in at least one area of ​​the rearview mirror and the light blocking member 540. can be.

[0048] As shown in FIGS. 14 to 16, the optical assembly 501 is disposed on the rear surface of the rearview mirror. The rearview mirror is connected to the storage space 560 of the back plate 690. , which may be the right mirror relative to the driver, for detecting and warning of external objects. The optical assembly 501 may be positioned outside the center of the backplate 690 .

[0049] An assembly in which left and right rearview mirrors 601, 603 of a moving object, for example, a vehicle, are joined together is , and each of the optical assemblies 501, 503 described above. The mirror 601 and 603 assemblies are identical and symmetrical to each other, so the right rearview mirror The above describes an example in which an optical assembly is applied within a laser assembly.

[0050] As shown in Figure 15, the driver is positioned on a virtual straight line PC, and the rearview mirror is positioned to the left and right. The indicator SM1 is exposed through the indicator, or when the lighting module 200 is driven, The indicator SM1 is displayed through a logo, icon, A rearview mirror is formed with at least one of a symbol and a mark shape for identification. 601, 603 and the light blocking member 540. For example, the indicator SM1 is formed on the rearview mirror 601, 603. The rearview mirrors 601 and 603 overlap with the opening OP1 of the light blocking member 540. In contrast to this, the indicator SM1 is disposed in an area where the light blocking member 5 40, and may be formed in the opening OP1 of the light blocking member 540. The rotor SM1 may overlap the first region Ra of the reflecting part 510 in the vertical direction. In addition, the indicator SM1 does not overlap the second region Rb of the reflecting portion 510 in the vertical direction. The indicator SM1 may be provided in one or more positions. For example, if a plurality of such indicators are provided, the first indicator The indicator is located on the driver's side (the designated area A1) and has an area larger than that of the second indicator. The second indicator may be provided in an area outside the first indicator. Alternatively, they may be arranged facing the object-side areas A2 and A3 or arranged at the outer lower part. The light emitted from the lighting module 200 is reflected by the reflecting portion 510 having an aspherical shape. The light is then incident on the opening OP1 of the light blocking member 540. The light emitted from the lighting module 200 is provided as a surface light source and illuminates the rearview mirror and and / or passing through the indicator SM1 formed on the light blocking member 540. This allows the indicator SM1 to be visually recognized from the outside. The rearview mirror assembly effectively provides the user with information about external objects. In addition, the light emitted from the lighting module 200 can be used as an indicator SM 1 to notify with a continuous alarm, a flashing alarm, or a gradually increasing brightness value. It can be provided in various forms such as a stepped down form.

[0051] As shown in FIGS. 15 to 17, left and right rearview mirrors 601 of a moving object, for example, a vehicle 801, 603 can include the optical assemblies 501 and 503 described above. The assemblies having mirrors 601 and 603 are identical in shape and symmetrical to each other, so for convenience of explanation, For convenience, the example applied to the right rearview mirror has been described. For example, When other moving bodies 803 or objects are located on the left and right sides of the vehicle based on the reference, the optical assembly The light emitted from the illumination module 200 of the assemblies 501 and 503 passes through the indicator. Therefore, the left and right rearview mirror assemblies The light emitted through the assembly is emitted in a set direction, for example, toward the driver. The different directions can have different brightness values.

[0052] Specifically, a virtual horizontal line passing through the rearview mirrors 601 and 603 located on the left or right side is If there is a line Ph and two lines Pc1 and Pc2 that are perpendicular to the horizontal line Ph, then the line P c1, the brightness value of the first area A1 located in the inner direction from Pc2, for example, the set area A1 The brightness of the second area A2 and the third area A3 located in the outward direction, for example, the object side areas A2 and A3 Specifically, the first area A1 may be different from the second area A2 and the third area A3. The reflective portion 510 may have a higher luminance value than the area A3. By forming the surface as an aspheric surface, it is possible to control the brightness value according to the direction of light emission. As an example, the light emitted to the first area A1, the second area A2, and the third area A3 is The brightness value of the light can be controlled. In either case, the luminance value can be controlled according to the direction of emission. The surface of the optical fiber 0 is formed as an aspherical surface, so that the first to third optical fibers pass through the opening OP1. The light emitted in the directions of the areas A1, A2, and A3 can have uniform brightness. Therefore, the embodiment can minimize the light loss and control the brightness value according to the emission direction. As a result, it is possible to effectively provide a driver of the vehicle with light of relatively high brightness, and the vehicle This allows the provision of light with a relatively low brightness to other moving objects located behind and to the side of the vehicle.
