Description

A STOP LAMP WITH CONDENSATION SYSTEM FOR USE IN AUTOMOTIVE SECTORTechnical Field of The Invention

[0001] The present invention relates to a lamp that is made entirely of thermoplastic material, has four functions as signal, position, reflector and stop functions, uses a bulb, and has high sealing properties with the seal design and condensation system in the lens-body area and body-socket plate (6) area. Condensation can generally be defined as the transition of water vapour in the atmosphere from gaseous to liquid, and it can also be defined as a product of the condensation of water vapour in the atmosphere that comes into contact with cold surfaces and liquefies on that surface and forms in the form of water droplets. In products where condensation problems occur, the water vapour in the air changes from gaseous to liquid as a result of contact with a surface at a lower temperature than the dew point, which depends on the ambient temperature and relative humidity. In headlights, lamps and similar devices operating under cold and hot conditions, when the hot moisture-loaded air formed during operation comes into contact with a very cold surface inside the frame, condensation occurs on the inner surfaces of the frame. Said invention relates to the use of a specially designed condensation system in order to prevent this condensation in the lamp in a way that cannot be intervened from outside.

[0002] In addition, the invention is characterised by providing more homogeneous illumination with the specially shaped faceted and high brightness surface that works as a reflector on the inner surface of the body (3).

[0003] The leak-proof lamp used in the automotive sector consists of Screw, Lens, Body, Stud, Reflector, Collimator, Separator Sheet, Bulb, Lens Gasket, Body, Stud, Chassis Contact, Long Contact, Short Contact, Bottom Contact, Ventilation Band (Condensation Band), Socket Plate Gasket, Socket Plate and Screw (back) parts and can be characterised by being easily integrated into all vehicles with a suitable connection with the bolt at the back.

[0004] Lamps in various shapes and numbers are used in automobiles, buses, minibuses, off-road vehicles, agricultural vehicles, construction machines, long-distance vehicles and all other vehicles due to highway requirements. These lamps must be designed in accordance with the required standards (ECE R148, ECE R150 etc.). In addition, all tractors and construction machines are of great importance in terms of human safety and possible risks.

[0005] The present invention relates to rear stop lamps that can be used in automobiles, buses, minibuses, off-road vehicles, agricultural vehicles, construction equipment, and in all vehicles suitable for assembly in transportation and similar sectors.Field of Invention

[0006] Generally, lamps used in the automotive sector are quite difficult to install on the body due to the cables on the back of the lamps coming out. Said invention is characterised by having no external cables and providing reliability and longer life compared to integrated systems with cables with an integrated connector, a sealed socket structure.State of the Art

[0007] In all tractors and construction equipment, additional parts such as o-rings are required to ensure sealing in lamps. Said invention is a lamp that comprises the sealing element without the need for an additional part, unlike the lamps used in state of the art, and has a condensation system that cannot be reached by the user with its special design in off-road vehicles that require high sealing.

[0008] In addition, with the condensation design being a contrasting / different colour in the invention, zero-fault product production will be ensured with the possibility of 100% digital automatic control in the production process.Brief Description of Invention

[0009] The present invention is a stop lamp made of thermoplastic material, characterised by its special ventilation design in the body (3) and lens (2) sections, where the sealing problem is most common in such lamps, and by its long-term trouble-free operation and high sealing feature under heavy field conditions compared to other products. In addition, with this special design, it has a condensation system that is not accessible by the user and this condensation design is a contrasting / different colour, and it can be controlled 100% automatically digitally, thus ensuring zero-fault product production.Detailed Description of the Invention

[0010] The present invention is made of thermoplastic material, has four functions as signal, position, reflector and stop functions, has a bulb structure, and has high sealing feature with its condensation system and the seal design in the lens-body area and body-socket plate area. In addition, the invention relates to providing more homogeneous illumination with its special faceted structure and high brightness surface on the inner surface of the body (3). Said lamps are designed in a way that will meet the legal requirements and in accordance with the required standards. Said invention is characterised by having no external cables and providing reliability and longer life compared to integrated systems with cables with an integrated connector, a sealed socket structure.Brief Description of the Drawings

[0015] The system generally consists of Screw, Lens, Body, Stud, Reflector, Collimator, Separator Sheet, Bulb, Lens Gasket, Body, Stud, Chassis Contact, Long Contact, Short Contact, Lower Contact, Ventilation Band (Condensation Band), Socket Plate Gasket, Socket Plate and Screw (back) parts.

[0016] Said stop lamp is generally designed to be used in automobiles, buses, minibuses, off-road vehicles, agricultural vehicles, construction equipment, and in all vehicles suitable for assembly in transportation and similar sectors, and is characterised by its special condensation system, which allows it to operate smoothly for a long time under heavy field conditions compared to other products, having high sealing properties and having a condensation system that cannot be reached by the user with its special design.

[0017] Said invention can be easily integrated into all vehicles with a suitable connection with the bolt in the rear area. It has a structure without external cables and an integrated connector. It has higher reliability and longer life compared to cable systems with its integrated connector, sealed socket structure without external cable. In order to provide said high sealing feature, detailed analyses are performed without affecting the optical feature of the lamp and a condensation system is added to the most suitable point of the lamp for volumetric condensation, which cannot be reached by the user, cannot be removed and cannot be damaged, with a special design. By means of the special faceted structure and high brightness surface on the inner surface of the body (3), it offers advanced optical features with more homogeneous lighting. The targeted condensation system design in said product is in a contrasting / different colour, and zero-fault production is ensured by being digitally controlled 100% automatically. With this special condensation system, a safer, more durable and longer-lasting product that can operate under harsh field conditions will be developed.

[0018] Said product is recommended for automobiles, buses, minibuses, off-road vehicles, agricultural vehicles, construction machinery, and all vehicles suitable for assembly in transportation and similar sectors and will be preferred due to its features and advantages.
