1 Introduction.
With the rapid economic development in recent years, the car’s design and manufacturing technology are also increasing, also gradually rich functionality of the car, the car has become an essential part of people’s daily lives. However, the possibility of driving a vehicle traffic accidents occur at night or in low-light situations, and can account for about 27% of the total traffic accidents, and most of the time there will be personal harm. So 3w led grow driving at night must have good lighting.
2 car lamps.
Automotive lamps from the 1880s, the world’s first light auto lighting classic cars hanging gas lamps to the development of the first electric lights in 1912. Early automotive incandescent lamps, the lighting is dim, in the situation of the increasing number of vehicles and continuously improve the speed, incandescent can not meet the day-to-day needs of the lighting, car lights and the development of higher brightness tungsten halogen lamps high-intensity discharge lamps, brake lights, turn to a series of lights, rear fog lamp types, played a key role in order to avoid driving at night, when the rear-end or turn collided. Lighting technology with improved productivity is also gradually developed, including light-emitting diode technology (Light Emitting Diode LED High Bay Bulbs ), especially in automotive lamps automotive lamps. Automotive design in recent years, more and more use of LED 3w led grow lights, modeling is more and more elegant, and the combination of various lamps use more to lead the trend and direction of today’s automotive lighting development.
3 car rear combination lamps of basic theory.
The cars in the process of driving, the rear combination lamp can be obvious characterization of the car driving, docked and the steering state, so that a variety of vehicle driver to make a more reliable adjustment, safe driving. Modern automobile rear lamps commonly used form of modular lighting the lights of the various functions in the same light body inside nice and easy car driver identification. General rear combination lamps, including brake lights, rear fog lamps, cornering lights, reversing lights, rear position lamps, these types of lights have their role, as follows:
The brake lights: the brake lights (brake lights) is mounted on the rear of the vehicle on both sides when driving the brake pedal is depressed, the brake lights that lit the red light to remind the vehicles behind Note, do not rear-end . Brake lights that go off when the brake pedal is released when the motorist.
Rear fog lamp: car rear fog lamp is low visibility in fog, snow, rain or dust diffuse environment, easy to find and installed in the rear of the vehicle to the rear of the vehicle to other road traffic participants, luminous intensity more than taillight large.
Turn lights: turn signal is open to vehicles and pedestrians around prompt attention to the important indicator in the motor 3w led grow vehicle steering.
Reversing lights: lighting behind the vehicle roads and warning other person using the road, the vehicle is reversing or about to lights, color is white.
Rear position lamps: commonly known as a small lamp, is mainly used to indicate the presence of the car and broad width, easy to make judgments of the other vehicles in the car will be and when overtaking.
