Description
Technical Field
The present invention relates to a vehicle lamp, and more particularly, to a vehicle lamp that forms a low beam pattern using light transmitted through a plurality of independent lenses.
Background
In general, a vehicle is equipped with a vehicle lamp having an illumination function for easily confirming an object located around the vehicle when traveling at night and a signaling function for notifying other vehicle drivers or pedestrians on the road of the traveling state of the vehicle.
For example, a vehicle lamp that operates to emit light directly from a lamp is equipped with a headlight that irradiates light forward to ensure a driver's field of vision, a brake light that is turned on when stepping on a brake, a winker light that is used when turning right or left, a backup light that is turned on when backing up, and the like.
The light irradiated toward the front of the vehicle may form a low beam pattern and a high beam pattern. The low beam pattern may be used to ensure a near field of view and the high beam pattern may be used to ensure a far field of view.
When the low beam pattern is formed using light transmitted through one lens, the form of the low beam pattern may be limited. The low beam pattern may be formed by overlapping a plurality of regions having optical densities and sizes different from each other, but light transmitted through one lens cannot accurately represent each region. Therefore, inventions in various fields capable of accurately presenting the low beam patterns are required.

Detailed Description
Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The advantages and features of the present invention and the methods of accomplishing the same may be understood by reference to the following detailed description of embodiments taken in conjunction with the accompanying drawings. However, the present invention may be embodied in various forms different from each other, and is not limited to the embodiments disclosed below, which are provided only for making the disclosure of the present invention complete and informing a person having ordinary knowledge in the art to which the present invention pertains of the scope of the present invention, which is defined only by the scope of the claims. Throughout the specification, the same reference numerals refer to the same constituent elements.
Unless otherwise defined, all terms (including technical and scientific terms) used in this specification are used in a meaning commonly understood by one having basic knowledge in the field to which the present invention belongs. Furthermore, unless explicitly and specifically defined otherwise, terms defined in commonly used dictionaries should not be interpreted as being ideal or overly formal.
Fig. 1 is a diagram showing a vehicular lamp according to an embodiment of the invention, and fig. 2 is a diagram showing a low beam pattern.
Referring to fig. 1, a lamp 1 for a vehicle according to an embodiment of the present invention may include a beam pattern forming portion 10.
The beam pattern forming part 10 may form a beam pattern. In the present invention, the beam pattern formed by the beam pattern forming section 10 may be a low beam pattern. The low beam pattern indicates a beam pattern irradiated to ensure a close-range view in front of the vehicle.
Referring to fig. 2, the low beam pattern 20 may include a spot beam pattern 21, an intermediate beam pattern 22, and a diffused beam pattern 23.
The spot beam patterns 21 may be arranged in a specific region of the low beam pattern 20 to ensure a visual field of the relevant region. The spot beam pattern 21 has a smaller area size than other beam patterns, and can have higher luminance. The spot beam pattern 21 can ensure a clear field of view for a portion directly seen by the driver.
The intermediate beam pattern 22 may be arranged in the entire area of the low beam pattern 20 to ensure the view of the vehicle front periphery. The intermediate beam pattern 22 has a larger area size and may have a lower brightness than the other beam patterns.
The diffused light beam pattern 23 may be arranged in a side region of the low beam pattern 20 to ensure a view of the vehicle front side. The diffused light beam pattern 23 may be a light beam pattern that irradiates only the traveling lane with light, and does not irradiate the oncoming lane with light.
As shown in fig. 2, the low beam pattern 20 may include: spot beam pattern 21, intermediate beam pattern 22, and diffuse beam pattern 23. At this time, the spot beam pattern 21, the intermediate beam pattern 22, and the diffused beam pattern 23 are overlapped with each other at least partially to form the low beam pattern 20.
When the spot beam pattern 21, the intermediate beam pattern 22, and the diffused beam pattern 23 are formed by one module, there is a possibility that the respective beam patterns cannot be clearly formed. Therefore, it is preferable to form the spot beam pattern 21, the intermediate beam pattern 22, and the diffused beam pattern 23, respectively, and overlap the formed plurality of beam patterns, thereby forming the low beam pattern 20.
The vehicle lamp 1 according to the embodiment of the invention can form the spot beam pattern 21, the intermediate beam pattern 22, and the diffused beam pattern 23 separately and overlap them to form the low beam pattern 20. As described with reference to fig. 1, a plurality of beam pattern forming units 10 may be provided. For example, the plurality of beam pattern forming parts 10 may be arranged in a line.
At least a part of the plurality of beam pattern forming parts 10 may form a spot beam pattern 21, another part of the plurality of beam pattern forming parts 10 may form an intermediate beam pattern 22, and yet another part of the plurality of beam pattern forming parts 10 may form a diffused beam pattern 23. Since the spot beam pattern 21, the intermediate beam pattern 22, and the diffused beam pattern 23 are individually formed by the different beam pattern forming portions 10, and the individually formed beam patterns 21, 22, and 23 are combined to form the low beam pattern, the light distribution to each region of the low beam pattern 20 is accurately formed, and the visual field of the driver can be effectively secured.
Fig. 3 is a perspective view of the beam pattern forming part shown in fig. 1, and fig. 4 is a side view of the beam pattern forming part shown in fig. 1.
Referring to fig. 3 and 4, the beam pattern forming part 10 according to the embodiment of the present invention includes: a light source 100, a reflector 200, and a lens 300.
The light source 100 may irradiate light. The Light source 100 may be one of an LED (Light Emitting Diode), a laser, or a bulb type Light source as a Light Emitting module generating Light. The light source 100 may irradiate light having a predetermined angle range, and for this, an additional lens (not shown) that concentrates or diffuses the light may be provided on a light irradiation path of the light source 100.
The reflector 200 may reflect the light of the light source 100. The light reflected by the reflector 200 may be transmitted to the lens 300. The lens 300 may transmit light incident from the reflector 200 to form a beam pattern.
Fig. 5 isbase:Sub>A sectional view ofbase:Sub>A-base:Sub>A' in fig. 3, and fig. 6 isbase:Sub>A view for explainingbase:Sub>A focal point of the reflecting surface.
Referring to fig. 5, the reflector 200 may include a plurality of reflecting surfaces 210.
The plurality of reflection surfaces 210 may reflect light toward the light incident part 311 of the corresponding light transmission part 310 among the plurality of light transmission parts 310 provided in the lens 300. For example, a first reflective surface 210 of the plurality of reflective surfaces 210 may reflect light toward the light incident portion 311 of the first light transmission section 310, and a second reflective surface 210 may reflect light toward the light incident portion 311 of the second light transmission section 310. Therefore, the light reflected by each of the plurality of reflection surfaces 210 can be incident to the light incident portion 311 of the light transmission portion 310 corresponding to the emission surface 210 in the manner of 1.
Adjacent ones of the plurality of reflective surfaces 210 may have a boundary, and each reflective surface 210 may reflect light in an individual direction. For this reason, the curvature and the facing direction may be formed for each reflecting surface 210.
Referring to fig. 6, the plurality of reflective surfaces 210 may have a first focal point F1 and a second focal point F2, respectively.
The first focus F1 may be located at the light source 100. The second focal point F2 may be located at a cutoff formation portion CP (refer to fig. 9) of the corresponding light transmission portion 310 among the plurality of light transmission portions 310 constituting the lens 300.
The light irradiated from the light source 100 may be transmitted to the plurality of reflection surfaces 210. When the light source 100 is disposed at the first focal point F1 of each of the plurality of reflection surfaces 210, each of the reflection surfaces 210 can efficiently receive the incident light of the light source 100.
Each of the reflective surfaces 210 may reflect incident light. At this time, each of the reflection surfaces 210 may reflect light toward the second focal point F2. When the first shielding part is disposed at the second focal point F2 of each of the plurality of reflection surfaces 210, the reflected light can be efficiently transmitted to the first shielding part.
Fig. 7 is a side view of the light transmission section.
Referring to fig. 7, light transmissive section 310 includes: a light incident portion 311 and a light emitting portion 312.
The light incident portion 311 may receive light incident from a corresponding reflection surface 210 among the plurality of reflection surfaces 210 included in the reflector 200. A specific reflection surface among the plurality of emission surfaces 210 included in the reflector 200 may correspond to a specific light transmission section 310 among the plurality of light transmission sections 310 included in the lens 300, and light reflected from the reflection surface may be incident to the light incident section 311 of the light transmission section 310.
In particular, the second focal point F2 of the reflection surface 210 is a position point of the first shielding portion 313a, and the first shielding portion 313a may be included inside the light transmission portion 310. Therefore, the light irradiated from the light source 100 may be transmitted to the lens 300 in a state of reduced light loss.
The light incident part 311 may have a curvature R. Specifically, the light incident part 311 may have a curvature R convex toward the reflector 200. As the light incident part 311 has the curvature R, the area of the light incident part 311 increases, and the amount of light incident through the light incident part 311 also increases.
Each of the plurality of reflection surfaces 210 may be arranged at an upper side than the light incident portion 311 of the corresponding light transmission portion 310. At this time, the light incident portion 311 may be inclined toward the corresponding reflection surface 210. As the light incident portion 311 is formed obliquely toward the reflection surface 210 disposed at the upper side, not only the actual area of the light incident portion 311 increases, but also the area of the light incident portion 311 viewed from the reflection surface 210 increases. Thus, the light incident portion 311 can receive the incidence of light in a state where the loss of light reflected from the reflection surface 210 is reduced.
The light emitting unit 312 can emit light incident on the light incident unit 311. The light emitting portion 312 may have a specific curvature, and may concentrate or diffuse the emitted light.
Fig. 8 is a perspective view of the rear surface of the lens, and fig. 9 is a sectional view of B-B' in fig. 3.
Referring to fig. 8 and 9, each light transmissive section 310 may include: a first shield part 313a and a second shield part 313b.
The first shielding portion 313a may block a part of light incident to the light incident portion 311, thereby forming a bright-dark cutoff in the beam pattern. On the surface of light transmission unit 310, first shielding unit 313a is formed as second shielding unit 313b protrudes in a semi-cylindrical manner.
To explain with reference to fig. 9, light transmitted to the blocking region BL in the entire region of the first shielding part 313a may be blocked at the blocking region BL not to be transmitted to the light exit part 312, or may be transmitted to the light exit part 312 after being reflected at the blocking region BL. The light transmitted to the pass-through region TH in the entire region of the first shielding part 313a may be transmitted to the light exit part 312 through the pass-through region TH.
The first shielding part 313a may include a cutoff formation part CP. A cutoff forming portion CP for forming a cutoff may be formed between the blocking region BL and the passing region TH, and light incident through the light incident portion 311 is emitted through the passing region TH, so that the cutoff may be formed in the low beam pattern 20.
Fig. 10 is a diagram showing a state where light is emitted in the beam pattern forming portion, and fig. 11 is a diagram for explaining a function of the second shielding portion.
Referring to fig. 10, light irradiated from the light source 100 is reflected by the reflector 200 to be incident on the lens 300, and the light incident on the lens 300 is emitted, so that a beam pattern may be formed.
The light irradiated from the light source 100 may be transmitted to the plurality of emission surfaces 210 included in the reflector 200. Each of the reflection surfaces 210 may reflect light incident toward the corresponding light transmission part 310.
The light reflected from the reflection surface 210 may be incident to the light transmission part 310 through the light incident part 311 of the light transmission part 310. The second focal point F2 of the reflection surface 210 may be located at the cutoff portion CP of the first shielding portion 313a. The incident light has a predetermined shape through the first shield portion 313a. The light passing through the first shielding portion 313a may be emitted through the light emitting portion 312 to form a beam pattern.
The first shielding portions 313a included in the plurality of light transmissive portions 310 arranged up and down may be spaced apart from each other. Fig. 10 shows a case where the light transmissive part 310 is arranged in three layers. The first shielding portions 313a of the light transmission portions 310 disposed at different layers from each other may be separated from each other with the second shielding portions 313b as a boundary.
Since an air layer exists between the specific light transmission part 310 and the other light transmission part 310, light incident to the light incident part 311 of the specific light transmission part 310 may be reflected at the surface of the first shielding part 313a without being transmitted to the air layer. That is, since the light incident on a specific light transmission unit 310 may not be incident on another light transmission unit 310, each light transmission unit 310 may emit only the light incident through its own light incident unit 311, and may not emit the light flowing out of another light transmission unit 310. As a result, each light transmission section 310 can emit light without being interfered by other light transmission sections 310, so that the light emitted by each light transmission section 310 can form a clear light beam pattern set in advance.
The second shielding part 313b may be formed to extend downward from the first shielding part 313a. The second shielding part 313b may block light, which is not incident to the light incident part 311, among the light reflected by the reflector 200, from being incident to the light transmitting part 310. The second shielding part 313b may be inclined toward the light incident part 311. This is to prevent the light reflected at the light emitting portion 312 from being reflected again to the light emitting portion 312.
As described with reference to fig. 11, some of the light transmitted through the inside of the light transmission part 310 and transmitted to the light exit part 312 may be reflected at the light exit part 312.
The light reflected from the light exit part 312 may be transmitted to the second shielding part 313b. When the arrangement angle of the second shielding part 313b is not proper, the second shielding part 313b may reflect the light incident from the light exit part 312 to the light exit part 312. For example, if the second shielding portion 313b is not formed to be inclined toward the light incident portion 311, the second shielding portion 313b may reflect light toward the light emitting portion 312.
The light emitted from the light emitting portion 312 after being reflected by the second shielding portion 313b is irradiated in an upper direction with respect to the optical axis of the light emitting portion 312, so that glare may be formed. The glare is a light beam pattern area that protrudes in a predetermined size in the low beam pattern, and may cause glare to a vehicle or a pedestrian traveling in front.
The second shielding part 313b is formed obliquely toward the light incident part 311, so that the light reflected at the light emitting part 312 and transmitted to the second shielding part 313b is blocked from being reflected again to the light emitting part 312, and the occurrence of a glare phenomenon can be prevented.
While the embodiments of the present invention have been described with reference to the above-mentioned contents and drawings, those skilled in the art to which the present invention pertains will appreciate that the present invention can be embodied in other specific forms without changing the technical ideas or essential features thereof. It is therefore to be understood that the above described embodiments are illustrative in all respects, not restrictive.
