Description

Lighting

Technical Field

The utility model relates to the technical field of automobile lamps, in particular to a lighting device.

Background technique

Headlights are tools for vehicles to illuminate the road at night, and are also tools for issuing various vehicle driving signals. Headlights are generally divided into headlights, taillights, turn signals, etc. With the development of technology, headlights are no longer satisfied with the functional requirements of lighting instructions. The importance of headlights to the appearance of a car is just like the importance of human eyes to personal image. In recent years, with the advancement of industrial manufacturing capabilities and chemical capabilities, headlights have been continuously upgraded, from the initial simple lighting to the current use for night vision, decoration, brand characteristics, etc. More and more automobile manufacturers require headlights to be exquisite and beautiful whether they are static or lit.

At present, thick-walled parts have been increasingly used in car signal lights. The light emitted by the light source can be emitted from the light-emitting surface of the thick-walled part after reflection. In order to ensure the light-emitting effect of the thick-walled part, the light-emitting part of the thick-walled part cannot be blocked, so the mounting structure inside the headlight is exposed, which not only affects the appearance, but also causes the stray light inside the lamp to leak out, and then leads to more bright spots and high-brightness stray light on the non-light-emitting surface of the headlight. The existing practice is to add decorative frames on the upper and lower sides of the thick-walled part (to block the internal mounting structure and stray light), and the two decorative frames are in contact with the thick-walled part to clamp the thick-walled part. The disadvantage of this approach is that due to the contact between the decorative frame and the thick-walled part, part of the reflected light inside the thick-walled part will be absorbed by the decorative frame, which will cause a layered black shadow defect to appear at the contact position of the thick-walled part and the decorative frame when the headlight is turned on, affecting the aesthetics.

In addition, features defined as "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present utility model, unless otherwise specified, "multiple" means two or more.

In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

As shown in Fig. 1 to Fig. 5, the lighting device of the utility model comprises: a light source module 1, a reflector 2, a thick-walled member 3, an upper decorative frame 5 and a lower decorative frame 6. The reflector 2 is used to reflect the light emitted by the light source module 1. The reflector 2 is provided with a first connecting portion 21 and a second connecting portion 22. The thick-walled member 3 is located at one side of the reflector 2. The thick-walled member 3 comprises: a light guide portion 31, a first fixed wing 32 and a second fixed wing 33. The first fixed wing 32 and the second fixed wing 33 are respectively located at both sides of the light guide portion 31. The upper decorative frame 5 is located at the upper side of the light guide portion 31, and the lower decorative frame 6 is located at the lower side of the light guide portion 31. Among them, the first fixed wing 32 is fixedly connected to the first connecting portion 21, and the second fixed wing 33 is fixedly connected to the second connecting portion 22. There is a first gap 7 between the upper decorative frame 5 and the light guide portion 31, and there is a second gap 8 between the lower decorative frame 6 and the light guide portion 31.

It should be noted that the light emitted by the light source module 1 enters the thick-walled member 3 after being reflected by the reflector 2, and finally is emitted from the light-emitting surface of the thick-walled member 3. The utility model improves the structure of the reflector 2 and the thick-walled member 3, so that the thick-walled member 3 can be fixedly connected to the reflector 2, and no longer needs to rely on the clamping force of the upper decorative frame 5 and the lower decorative frame 6. Furthermore, the upper decorative frame 5, the lower decorative frame 6 and the thick-walled member 3 are not in contact, thereby improving the stacked black shadow defect.

For example, the first fixing wing 32 is fixedly connected to the first connecting portion 21 by means of screws 4 , and the second fixing wing 33 is fixedly connected to the second connecting portion 22 by means of screws 4 .

For example, the light source module 1 includes a circuit board 101 and an LED light source 102, and the LED light source 102 is arranged on the circuit board 101. The light source module 1 is located below the reflector 2, and a light inlet 24 is provided on the lower side of the reflector 2, and the LED light source 102 is located directly below the light inlet 24. The reflector 2 also includes a reflective portion 23, and the light emitted by the LED light source 102 can be reflected by the reflective portion 23 and then enter the light guide portion 31. The first connecting portion 21 and the second connecting portion 22 are respectively located on the upper and lower sides of the reflector 2.

The lighting device of the utility model also includes: a light-uniform inner lampshade 11, and the light-uniform inner lampshade 11 is located between the reflector 2 and the thick-walled part 3. The light-entering surface and/or the light-emitting surface of the light-uniform inner lampshade 11 are provided with leather grain. It should be noted that the light-uniform inner lampshade 11 is installed at one end of the reflector 2 close to the thick-walled part 3, and when the thick-walled part 3 is connected to the reflector 2, the light-uniform inner lampshade 11 can be fixed together. The light-uniform inner lampshade 11 can improve the uniformity of light distribution. The light-entering surface (left end surface) and/or the light-emitting surface (right end surface) of the light-uniform inner lampshade 11 are provided with leather grain. Simply relying on materials to improve the light-uniform effect has high requirements on the materials and is expensive. Improving the light-uniform effect of the light-uniform inner lampshade 11 by adding leather grains is conducive to reducing costs.

For example, the upper decorative frame 5 includes a first shielding arm 51, and a first gap 7 is provided between the first shielding arm 51 and the upper side surface of the light guide portion 31, and the range of the first gap 7 is 0.5 mm to 1.5 mm (including the end points). The lower decorative frame 6 includes a second shielding arm 61, and a second gap 8 is provided between the second shielding arm 61 and the lower side surface of the light guide portion 31, and the range of the second gap 8 is 0.5 mm to 1.5 mm (including the end points). The upper decorative frame 5 and the lower decorative frame 6 can block the connection part (i.e., the connection part and the fixed wing) between the reflector 2 and the thick-walled member 3, and when observed from the outside, the human eye can only see the light guide portion 31. Most decorative frames are dark in color, and the shielding effect is better. For the first gap 7 and the second gap 8, if the gap is too small, due to the processing tolerance of the decorative frame and the light guide portion 31, the decorative frame may still contact the light guide portion 31; if the gap is too large, the shielding effect of the decorative frame may be weakened, and more installation space may be wasted.

For example, there is a third gap 9 between the end face of the first shielding arm 51 close to the reflector 2 (i.e., the left end face) and the first fixed wing 32. There is a fourth gap 10 between the end face of the second shielding arm 61 close to the reflector 2 (i.e., the left end face) and the second fixed wing 33. The value ranges of the third gap 9 and the fourth gap 10 are both 0.5 mm to 1.5 mm (including the end points). That is, there is no contact between the left end face of the shielding arm and the fixed wing. When the lighting device is in use, vibration will be generated as the car travels. If the left end face of the shielding arm contacts the fixed wing, the continuous vibration will cause wear of the shielding arm and the fixed wing, shortening the service life of the lighting device. As a result, the shielding arm does not contact the light guide portion 31, which can also reduce the wear of the decorative frame and the light guide portion 31.

For example, the orthographic projection area of the plane P where the upper decorative frame 5 is located in the width direction of the light guide portion 31 is larger than the orthographic projection area of the first fixed wing 32 on the plane P. The orthographic projection area of the plane P where the lower decorative frame 6 is located in the width direction of the light guide portion 31 is larger than the orthographic projection area of the second fixed wing 33 on the plane P. In this way, the shielding effect can be improved, thereby improving the aesthetics of the headlight.

For example, the light incident surface (left end surface) of the light guide portion 31 is provided with skin texture, and the orthographic projection area of the skin texture of the light incident surface of the light guide portion 31 on the plane P where the width direction of the light guide portion 31 is located is larger than the orthographic projection area of the light emitting surface (right end surface) of the light guide portion 31 on the plane P. In this way, it is helpful to improve the uniformity of light emission.

For example, the lighting device further includes: a housing 12 and an outer lampshade 13, the housing 12 and the outer lampshade 13 are connected to form an installation space, and the light source module 1, the reflector 2, the thick-walled member 3, the upper decorative frame 5 and the lower decorative frame 6 are all located in the installation space. The reflector 2 is connected and fixed to the housing 12, the circuit board 101 is connected and fixed to the reflector 2, the upper end of the upper decorative frame 5 is connected and fixed to the first connecting portion 21 (not shown in the fixing structure diagram), and the lower decorative frame 6 is fixed to the housing 12 through the structural member 14 (not shown in the fixing structure diagram).

In summary, the lighting device of the present invention improves the structure of the reflector 2 and the thick-walled member 3, so that the thick-walled member 3 can be fixedly connected to the reflector 2, and no longer needs to rely on the clamping force of the upper decorative frame 5 and the lower decorative frame 6. In addition, the upper decorative frame 5, the lower decorative frame 6 and the thick-walled member 3 are not in contact, thereby improving the defect of stacked black shadows and further improving the aesthetics of the vehicle lamp.

Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without departing from the technical concept of the utility model through the above description. The technical scope of the utility model is not limited to the content of the specification, but must be determined according to the scope of the claims.
