Description

Technical Field

[0001] This utility model relates to the field of automotive lighting technology, and more specifically, to an automotive lamp based on an internal reflector lens. Background Technology

[0002] Automotive lights are crucial safety and functional components of vehicles, primarily used for illuminating roads. Automotive lights have evolved from early halogen lamps to brighter, lower-energy-consumption xenon lamps (HID) and LED lights. The proper use of automotive lights is not only related to driving safety but is also a basic requirement of traffic regulations. Drivers need to operate them correctly according to different scenarios to avoid light pollution and safety hazards.

[0003] Traditional automotive lights typically use a combination of reflectors and lenses to converge and distribute light. The reflectors and lenses require considerable space to arrange, resulting in a large overall size for the light headlight, which is detrimental to vehicle design. Secondly, during use, light undergoes multiple reflections and refractions between the reflectors and lenses, causing light energy loss and reducing luminous efficiency. Finally, the combination of reflectors and lenses creates a complex internal structure for the light headlight, leading to heat buildup and affecting its lifespan. Therefore, we propose an automotive light based on an internal reflector lens. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide an automotive lamp based on an internal reflector lens. This addresses the technical problems of current automotive lamps, which typically use a combination of reflectors and lenses to achieve light convergence and distribution, resulting in large size, low luminous efficiency, and poor heat dissipation.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an automotive lamp based on an internal reflector lens, comprising a mounting mechanism and an internal reflector lens body disposed on the mounting mechanism. The mounting mechanism includes a lamp housing, with uniformly distributed heat dissipation aluminum rods disposed at the lower end of the lamp housing, and a mounting groove disposed at the upper end of the lamp housing. A circuit board is disposed in the mounting groove, and a pad is disposed at the upper end of the circuit board. The pad has a frame structure. An LED light source is disposed on the circuit board, and a total of three LED light sources are provided. A protruding sealing part is disposed at the rear edge of the internal reflector lens body.

[0006] Preferably, mounting plates are symmetrically arranged on both sides of the lower end face of the lamp housing, and a hidden groove is provided at the front end of the mounting plate. Bolts are provided in the hidden grooves, and a fixing bracket is installed between the mounting plates by bolts.

[0007] Preferably, a lamp holder is installed at the lower end of the lamp housing, and the conductive element of the lamp holder extends into the lamp housing, and the circuit board is connected to the conductive element.

[0008] Preferably, a sealing groove is provided at the upper edge of the lamp housing, the sealing groove is located outside the mounting groove, the size of the sealing part is adapted to the size of the sealing groove, and the sealing part is inserted into the sealing groove.

[0009] Preferably, the rear end of the inner reflective lens body is symmetrically provided with mounting posts, and the circuit board and the pad are both provided with mounting holes corresponding to the positions of the mounting posts. The mounting posts pass through the mounting holes of the circuit board and the pad and are connected to the lamp housing.

[0010] Preferably, the reflective surface includes symmetrically arranged focusing areas, a diffusion area is provided outside the focusing areas, and a reflection area is provided outside the diffusion area. The three LED light sources correspond to the reflection areas located between the two focusing areas.

[0012] Preferably, the diffusion area is composed of several annular lenses, the diameter of which gradually decreases from front to back, and the diameter of which gradually increases from inside to outside. The reflection area is composed of several uniformly distributed rectangular lenses, which are arranged at an angle to form a grid shape.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model, through the design of an internal reflective lens body structure, integrates reflection and refraction functions into the internal reflective lens body, reducing light energy loss and increasing luminous efficiency. It abandons the traditional separate scheme of reflector and lens combination, avoiding the need for independent lenses and circuit boards for different light patterns, simplifying the internal structure, reducing material and assembly costs in the manufacturing process, significantly reducing the overall size of the car lamp, avoiding complex internal structures, and facilitating heat dissipation with the heat dissipation aluminum rod. Compared with traditional car lamps, it better meets the high requirements of modern automotive styling design for space utilization, providing automotive designers with more flexible design space, and can meet the diverse layout needs of different models. It solves the problems of large size, low luminous efficiency, and poor heat dissipation in current car lamps that usually use a combination of reflectors and lenses to achieve light convergence and distribution.

[0014] 2. This utility model also features a unique reflective surface structure. The unique reflective surface structure allows the light emitted by the three LED light sources to be specifically processed by the focusing, diffusion, and reflection areas of the reflective surface. The spherical structure at the front and rear ends of the focusing area, combined with the recessed design, achieves initial convergence and secondary refraction of the light, effectively reducing light scattering loss. The gradient ring lens structure in the diffusion area ensures uniform light diffusion.

Detailed Implementation

[0017] like Figures 1 to 7As shown, this utility model relates to an automotive lamp based on an internal reflector lens, including a mounting mechanism 100 and an internal reflector lens body 201 mounted on the mounting mechanism 100. The mounting mechanism 100 includes a lamp housing 101, with uniformly distributed heat dissipation aluminum rods 102 at the lower end of the lamp housing 101, and a mounting groove 1011 at the upper end of the lamp housing 101. A circuit board 107 is mounted in the mounting groove 1011, and a pad 108 is mounted on the upper end of the circuit board 107. The pad 108 has a frame structure. An LED light source 202 is mounted on the circuit board 107. There are three LED light sources 202 in total. A protruding sealing part 204 is provided at the rear edge of the internal reflector lens body 201. The front end of the internal reflector lens body 201 is the light-emitting surface 2011, and the rear end of the internal reflector lens body 201 is the reflective surface 2012. This utility model integrates reflection and refraction functions based on an internal reflective lens, reducing light energy loss and improving light efficiency; it simplifies the structure, reduces costs and shrinks the size; the unique reflective surface 2012 optimizes light, and the heat dissipation aluminum rod 102 provides efficient heat dissipation, effectively solving the shortcomings of traditional vehicle lights.

[0018] Specifically, mounting plates 103 are symmetrically arranged on both sides of the lower end face of the lamp housing 101. A hidden groove 104 is provided at the front end of the mounting plate 103. Bolts are provided in the hidden groove 104. A fixing bracket 105 is installed between the mounting plates 103 by bolts.

[0019] Furthermore, a lamp holder 106 is mounted on the lower end of the lamp housing 101, and the conductive element of the lamp holder 106 extends into the lamp housing 101. The circuit board 107 is connected to the conductive element. The lamp holder 106 is configured to connect to the vehicle's internal electrical circuitry.

[0020] Furthermore, a sealing groove 109 is provided at the upper edge of the lamp housing 101. The sealing groove 109 is located outside the mounting groove 1011, and the size of the sealing part 204 is adapted to the size of the sealing groove 109. The sealing part 204 is inserted into the sealing groove 109. The sealing groove 109 is not only used for sealing the vehicle lamp, but also for assisting in the installation and positioning of the inner reflector lens body 201.

[0021] Furthermore, the rear end of the inner reflective lens body 201 is symmetrically provided with mounting posts 203. Both the circuit board 107 and the pad 108 have mounting holes corresponding to the positions of the mounting posts 203. The mounting posts 203 pass through the mounting holes of the circuit board 107 and the pad 108 and connect to the lamp housing 101. The mounting posts 203 are used to install and fix the circuit board 107 and the pad 108.

[0022] It is worth noting that the reflective surface 2012 includes symmetrically arranged focusing areas 2013, a diffusion area 2014 on the outer side of the focusing area 2013, and a reflective area 2015 on the outer side of the diffusion area 2014. The three LED light sources 202 correspond to the two focusing areas 2013 and the reflective area 2015 located between them. This one-to-one correspondence ensures that the light emitted by each LED light source 202 is specifically processed by the corresponding area of ​​the reflective surface 2012, reducing ineffective reflection and refraction of light within the luminaire, maximizing the conversion of light energy into effective illumination light, improving luminous efficiency, achieving brighter illumination at the same power, and reducing energy consumption.

[0023] It's worth noting that the focusing area 2013 is cylindrical, with a concave spherical front end and a convex spherical rear end. The convex spherical rear end has evenly distributed pits, forming the surface of a golf ball. The concave spherical front end of the focusing area 2013 initially converges the diverging light emitted from the light source, reducing light scattering loss and increasing the central light intensity. The convex rear end, combined with the concave front end, creates a lens-like effect, further adjusting the light angle through secondary refraction, resulting in a more uniform light spot distribution.

[0024] It is worth noting that the diffusion zone 2014 is composed of several annular lenses, with the diameter of the annular lenses gradually decreasing from front to back, and the diameter of the annular lenses gradually increasing from the inside to the outside. The reflection zone 2015 is composed of several uniformly distributed rectangular lenses, which are arranged at an angle to form a grid shape. The diffuser zone 2014 features a small-diameter lens with a small radius of curvature in the central area, achieving a focusing effect. The outer area features a large-diameter lens with a large radius of curvature, enhancing lateral diffusion. The gradient ring structure reduces abrupt transitions in light across different areas, preventing bright and dark spots and improving the uniformity of overall light distribution. The reflection zone 2015 consists of tilted rectangular lenses forming a grid-like reflective surface 2012. Each rectangular unit can function as an independent reflective unit, reflecting light from multiple angles. Furthermore, the composite structure of the focusing zone 2013, diffuser zone 2014, and reflection zone 2015 achieves multiple optical functions such as focusing, diffusion, and reflection through a single lens, replacing the traditional discrete "mirror + multiple lenses" approach. This combination reduces light energy loss, increases light efficiency, simplifies the structure, and reduces volume, avoiding the problems of large size and high cost associated with separate lenses and circuit boards 107 for different light patterns.

[0025] Working Principle: This embodiment provides an automotive lamp based on an internal reflector lens. When the lamp is connected to the circuit, current is transmitted to the circuit board 107 through the conductive elements of the lamp holder 106. The circuit board 107 processes and distributes the current to power the three LED light sources 202, causing them to emit light. The light emitted by the three LED light sources 202 corresponds to the two focusing areas 2013 on the reflective surface 2012 and the reflection area 2015 located between the focusing areas 2013. Light entering the focusing area 2013 is initially converged by the concave spherical surface at the front end, reducing light scattering loss and increasing the central light intensity. Subsequently, the light is further adjusted by the microstructure scattering effect generated by the pits on the convex structure at the rear end, which has a golf ball-shaped surface, making the light spot distribution more uniform. Light entering the reflection area 2015 is tilted... A rectangular lens forming a grid shape is used for multi-angle reflection to adjust the direction of light. In the diffusion area 2014, a ring lens with a diameter that gradually decreases from front to back and gradually increases from inside to outside diffuses the light in layers. The central area achieves a focusing effect, reducing light energy loss and increasing luminous efficiency. The outer area enhances lateral diffusion to ensure that the light uniformly covers the required lighting area. The light, after being processed by the focusing area 2013, diffusion area 2014 and reflection area 2015, is finally emitted through the light-emitting surface 2011 of the inner reflective lens body 201, forming a light pattern that meets the needs of automotive lighting. During operation, the LED light source 202 generates heat. The heat dissipation aluminum rods 102 evenly distributed at the lower end of the lamp housing 101 can quickly conduct the heat away and dissipate it into the surrounding environment, preventing heat from accumulating inside the lamp and ensuring the stable operation and service life of the automotive lamp.
