Description

Technical Field

[0001] This utility model relates to the field of automotive lighting technology, specifically a multi-functional combination lamp. Background Technology

[0002] Automotive lights are tools used to illuminate roads when vehicles are driving at night, and also to provide various vehicle driving signals. Automotive lights are generally divided into headlights, taillights, turn signals, etc.

[0003] However, existing auxiliary high beams are independent of the car's headlight assembly. The auxiliary low beam has a large power, requiring a large heat sink area, which increases the weight and cost of the entire lamp. At the same time, it also serves as a position light, with the light-emitting function sharing a single light-emitting surface. This limits the optical pattern of the corresponding mask. Furthermore, the large optical area of ​​the auxiliary high beam can cause light leakage in the position light module, creating bright spots. Utility Model Content

[0004] The purpose of this utility model is to provide a multifunctional combination lamp to solve the problem mentioned in the background art that the auxiliary high beam lamps generally have poor heat dissipation and the light-emitting surfaces are the same, which easily leads to light leakage.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multifunctional combination lamp, comprising:

[0006] The lamp housing has a PC lens at its front end and a heat dissipation back cover at its back. Four auxiliary high beam reflectors are arranged in a row inside the lamp housing. A position light lens is located below the front side of each auxiliary high beam reflector, and an ambient light guide plate is located below each auxiliary high beam reflector.

[0007] Preferably, the PC lens is fixedly connected to the lampshade housing.

[0008] Preferably, the heat dissipation back cover is fixedly connected to the lamp cover housing.

[0009] Preferably, the surface of the heat dissipation shell is provided with knurling.

[0010] Preferably, four auxiliary high beam reflectors are provided and are evenly and fixedly installed inside the lamp housing.

[0011] Preferably, the position light lens is fixedly connected to the auxiliary high beam cup, and the ambient light guide plate is fixedly connected to the lamp cover housing.

[0012] Preferably, the ambient light guide plate has holes for the corresponding position light lens, and the position light lens is also fixedly connected to the lamp cover housing.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) When the utility model multifunctional combination lamp is used, the heat dissipation shell is placed outside to serve as the lamp housing. At the same time, the heat sink is grooved according to a certain proportion, and several heat sinks of about five millimeters are spaced out, which can achieve a good weight reduction. In addition, each heat sink has a knurled design on its surface to achieve a larger heat dissipation area.

[0015] (2) When this utility model multifunctional combination light is in use, the auxiliary high beam is the main function and the optical area is used to the maximum extent. This function uses four auxiliary high beam cups to redistribute the illumination area. The lateral distance between a single auxiliary high beam cup is 60 mm. The reflective surface of the auxiliary high beam cup is divided into two parts. The central part is the main area. The reflective surface of this area is further divided to play the role of red energy in the main illumination area. The remaining part is auxiliary and has a low utilization rate. Therefore, it is reused with the ambient light function, which reasonably integrates the ambient light function without affecting the distribution of auxiliary high beam.

[0016] (3) When using this utility model multifunctional combination light, a small lens is used to meet the position light function. The position light module also uses the side-emitting mode. First, it avoids the main light-emitting area of ​​the auxiliary high beam. Second, it can achieve a more uniform lighting effect. The ambient light function is an additional function. Without affecting the auxiliary high beam and reusing the same auxiliary high beam reflector, it can also effectively shield the internal structure of the entire light while lighting up, achieving a multifunctional combination with better heat dissipation. While meeting the requirements of auxiliary lighting and signal warning, it also takes into account the lighting effect. The multifunctional functions coexist. Attached image description:

The PC lens 02 converts point or line light sources into surface light sources through uniformly distributed diffuser particles, resulting in more even light distribution and avoiding glare and light spots. This is especially suitable for scenarios requiring large-area soft lighting. A heat dissipation back cover 03 is located on the back of the lampshade housing 01, serving as the lamp housing component. The heat sink is grooved at a certain ratio, with several approximately 5mm heat dissipation fins spaced apart, effectively reducing weight. Four auxiliary high beam reflectors 04 are arranged in a row inside the lampshade housing 01, serving as the primary function for auxiliary high beams. The optical area uses... The maximum, in which this function uses four auxiliary high beam cups 04 to redistribute the illumination area, the lateral distance between a single auxiliary high beam cup 04 is 60 mm, and a position light lens 05 is set on the lower front side of the auxiliary high beam cup 04. A small lens is used to meet the position light function. The position light module also uses the side-emitting mode, firstly to avoid the main light emission area of ​​the auxiliary high beam, and secondly to achieve a more uniform lighting effect. An ambient light guide plate 06 is set below the auxiliary high beam cup 04. The ambient light function is an additional function. Under the premise of not affecting the auxiliary high beam and reusing the same auxiliary high beam cup 04, it can also effectively shield the internal structure of the entire lamp while illuminating.

[0026] Furthermore, the PC lens 02 is fixedly connected to the lampshade housing 01. The PC lens 02 converts point light sources or line light sources into surface light sources through the uniformly distributed diffusion particles inside, making the light distribution more uniform and avoiding glare and light spot phenomena. It is especially suitable for scenes that require large-area soft lighting.

[0027] Furthermore, the heat dissipation back shell 03 is fixedly connected to the lamp cover shell 01. The heat dissipation back shell 03 is externally placed to serve as the lamp housing of the lamp. At the same time, the heat sink is grooved according to a certain proportion, and several heat dissipation fins of about five millimeters are spaced out, which can achieve a good weight reduction.

[0028] Furthermore, the surface of the heat dissipation back cover 03 is knurled, and each heat sink has a knurled design to achieve a larger heat dissipation area.

The auxiliary high beam is the main function and the optical area is used to the maximum extent. This function uses four auxiliary high beam reflectors 04 to redistribute the illumination area. The lateral distance between a single auxiliary high beam reflector 04 is sixty millimeters.

[0030] Furthermore, the position light lens 05 is fixedly connected to the auxiliary high beam reflector 04, using a small-sized lens to fulfill the position light function. The position light module also uses a side-emitting mode, firstly avoiding the main light-emitting area of ​​the auxiliary high beam, and secondly achieving a more uniform lighting effect. The ambient light guide plate 06 is fixedly connected to the lamp housing 01. The ambient light function is an additional function. Without affecting the auxiliary high beam and reusing the same auxiliary high beam reflector 04, it can effectively shield the internal structure of the entire lamp while illuminating it.

[0031] Furthermore, the ambient light guide plate 06 has holes corresponding to the position light lens 05 to ensure that the ambient light guide plate 06 does not affect the installation of the position light lens 05. The position light lens 05 is also fixedly connected to the lamp housing 01. A small-sized lens is used to meet the position light function. The position light module also uses a side-emitting mode, which firstly avoids the main emission area of ​​the auxiliary high beam, and secondly can achieve a more uniform lighting effect.
