Detailed ways

The aforementioned and other technical contents, features and effects of the present invention will be clearly presented in the following detailed description of a preferred embodiment with reference to the accompanying drawings. the

Referring to Figures 2 and 3, it is a preferred embodiment of the utility model car lamp, which includes a base 2, and a main light unit 3, a secondary light unit 4, a decorative plate 5, and a base 2 arranged on the base 2. lampshade6. the

In this preferred embodiment, the car light is described as a motorcycle headlight, but of course the car light can be a lamp at any position on a motorcycle, or a lamp on a car, and it is not limited thereto. the

The main light unit 3 is used for the lighting in front of the car, and includes a reflector 31 and a main light 32 positioned on the reflector 31. The main light 32 usually adopts a halogen lamp and can emit high brightness for illumination. , but at the same time emit high heat. The sub-lamp unit 4 includes a light guide bar 41, a first fixing module 42, a second fixing module 43 for fixing both ends of the light guide bar 41 on the base 2, and a The light emitting module 44 on the first fixed module 42 . the

The light guide strip 41 is a transparent plastic strip with light guide lines 411 on its surface. In this preferred embodiment, the light guide pattern 411 of the light guide strip 41 is a downward zigzag pattern as shown in FIG. The light incident on the light guide strip 41 is led out. the

5 and 6, the first fixed module 42 has a connecting portion 421 connected to the light guide strip 41, two pins 425 arranged on the connecting portion 421, and a screw hole 426 on the connecting portion 421. , two docking portions 422 connected to the connecting portion 421 , and two receiving portions 423 fixed on the base 2 , and the auxiliary lamp unit 4 further includes a plurality of screws 45 . The light emitting module 44 has a circuit board 441 , two slots 442 disposed on the circuit board 441 , a through hole 444 and a light source 443 , and the light source 443 is a light emitting diode. These docking parts 422 correspond to these receiving parts 423 respectively, and can be locked and fixed on the corresponding receiving parts 423 by two screws 45, so that one end of the light guide strip 41 can be firmly combined on the base 2 , and after the slots 442 of the light emitting module 44 are respectively threaded on the pins 425, the through holes 444 can be aligned with the screw holes 426 for the corresponding screws 45 to be locked, and the light emitting module 44 can be combined On the connecting portion 421 , the light emitting direction of the light emitting source 443 faces the light guide bar 41 . the

In this preferred embodiment, the light source 443 is a square light emitting diode, but of course the light source 443 can also be a round or other shape light emitting diode, not limited thereto. In addition, the light emitting source 443 can be directly burnt on the circuit board 441 and cannot be separated, of course, it can also be soldered to the circuit board 441 after being inserted on the circuit board 441, so that the light emitting source 443 When there is damage, it is easier to replace and repair. the

2 and 7, the second fixing module 43 has two fixing plates 431, and these fixing plates 431 can also be locked and fixed on the base 2 by two screws 45, and the auxiliary lamp unit 4 is After the first fixed module 42 and the second fixed module 43 are combined with the base 2, it will be as shown in FIG. 7 . the

In particular, after the light guide strip 41 is fixed on the base 2, the distance A1 between the light source 443 (see FIG. 6 ) of the light emitting module 44 and the center of the main light 32 is the distance A1 between the outer edge of the reflector 31 and the center of the main lamp 32. The center of the main light 32 is more than 1.3 times the distance A2, so the light source 443 is less susceptible to the thermal effect of the main light 32 . the

In this preferred embodiment, the first fixing module 42 is located at the upper end of the light guide bar 41, so that the upper end of the light guide bar 41 can be fixed on the base 2 and used for combining the light emitting module 44. , and the second fixing module 43 is any form that enables the lower end of the light guide bar 41 to be combined with the base 2, but of course the first fixing module 42 can also be located at the lower end of the light guide bar 41 , not limited to this. In addition, the second fixing module 43 can also be the same as the first fixing module 42, and can be combined with another light-emitting module 44, so that light sources can be provided at both ends of the light guide strip 41, so that the The brightness of the light guide strip 41 can be improved. In addition, the number of light emitting sources 443 arranged on the circuit board 441 can be planned according to actual needs, and is not limited to one. the

In particular, the light guide strip 41 is integrally formed with the first fixed module 42 and the second fixed module 43, so the connection between them is quite stable, but the light guide strip 41 and the first fixed module 42 And the second fixed module 43 can also be manufactured separately and then combined together, not limited thereto. the

Referring to Figures 2 and 3 again, after the decorative plate 5 is combined on the base 2, it can outline the line aesthetic feeling of the car lamp, and can block the first fixed module 42, the second fixed module 43 and the inside of the base 2. The complex structure can make the vision more concise and bright. The lampshade 6 is made of a transparent material and can cover and protect the main lamp unit 3, the auxiliary lamp unit 4, and the decoration plate 5 arranged on the base 2, so as to avoid damage from wind and rain. the

When the car light is in use, turn on the light emitting module 44, and the light emitted by the light source 443 will penetrate into the transparent light guide strip 41, and be guided out by the light guide lines 411 and extend to the entire guide strip. The light bar 41, so that the light guide bar 41 is in the form of a light bar as a whole. When the sky is still bright and there is no need to turn on the main light unit 3 to provide lighting, the user can turn on the light emitting module 44 alone to make the light guide strip 41 light up, thereby making it clearer to passers-by Know the location of the vehicle accurately to improve driving safety. When the sky is dark, the user can turn on the main light unit 3 and the light-emitting module 44 at the same time, and the light guide strip 41 will create a line of light in addition to the functional lighting provided by the main light unit 3 . It can make the car light more personalized and design sense. the

To sum up, the light emitted by the light emitting source 443 of the vehicle light of the present invention can be transmitted and extended to the entire light guide strip 41, so the effect of a light bar can be achieved with a small number of light emitting sources 443 , greatly reducing the cost of materials. In addition, because the distance A1 between the light source 443 of the light module 44 and the center of the main light 32 is more than 1.3 times the distance A2 between the outer edge of the reflector 31 and the center of the main light 32, the light source 443 is less susceptible to The main lamp 32 is deteriorated due to the influence of heat effect, which can prolong the service life. Furthermore, the light guided by the light guide strip 41 is relatively soft and does not have excessively high brightness as known, and can avoid discomfort to passers-by caused by too dazzling light, so the purpose of the present utility model can indeed be achieved. . the

But above-mentioned person, only preferred embodiment of the present utility model, should not limit the scope of the present utility model implementation with this, promptly all the simple equivalent changes that are made according to the claims of the utility model and utility model explanatory content and modification, all still belong to the scope covered by the utility model patent. the
