Most of the time, the rise of new technologies is to make complexity simple. The complex engine was replaced by a simpler machine-controlled electronic motor; the laser-radar industry, which is driven by fire, has gradually developed a mass-produced solid-state solution; and the CD players that are common in high school and high school have long been replaced. , disappeared from our daily life. However, the new products that Texas Instruments recently released have to do the opposite. The car headlight system uses Texas Instruments' digital illumination processing technology to precisely control the beam with more than 1 million addressable pixels. At present, the system is mainly used in the field of cinemas and projectors, and contains a large number of "micromirrors" that are active and small and movable. These micromirrors can be flipped up to 10,000 times per second, either by reflecting light through a lens to produce white pixels, or by generating black pixels on a black absorption surface. This is like controlling the on and off of each pixel. This new technology can create a smarter headlight system for the vehicle. By programming, it can control the light of the headlights without the driver of the incoming car being shaken. It can even project text, images and even animations on the road ahead. Of course, Texas Instruments is demonstrating that the system is also intended to be used by OEMs and automotive lighting suppliers to market the DLP5531-Q1 chipset that performs programming functions. In fact, Texas Instruments is not the first company to introduce digital programming headlight technology. Last year Audi also released a similar laser headlight system. But Texas Instruments' system is said to have the highest resolution ever, and it can be used with any light source, without worrying about replacing the more common LED sources with cool but expensive laser technology. The most common application scenario for this system is that you can continue to use the high beam even if you have a car on the opposite side. The system uses an on-board camera to track the headlights on the opposite side of the car, automatically reducing the brightness of the beam to the other vehicle, and as the vehicle approaches, the brightness of the headlights will be lower and lower. The technology can also work with sensors on the vehicle to help drivers discover things on the road that require special attention, such as roadside traffic signs and small animals that are about to rush to the road. Ultimately, this lighting system is likely to become an integral part of autonomous vehicles in the future. Brian Ballard, Texas Instruments' external lighting business manager, said, "We designed the chipset to support adaptive lighting systems while also being able to project information on the road." For example, driverless cars can't communicate with the pedestrians on the road because they don't have drivers. Especially at some intersections without signal lights, it is a big problem to judge who is going first. This lighting system from Texas Instruments can solve this problem by projecting a crosswalk on the road ahead and even projecting words such as “Pedestrian Priorityâ€. However, the system is not officially named yet. Texas Instruments said that some of its OEM customers are already integrating this technology into existing headlight lighting systems, but will not be mass-produced in the short term. In addition, this adaptive driving lighting system is currently not legal in the United States, because the law requires that the high beam and low beam of the vehicle have separate light sources, but it is obvious that the lighting system developed by Texas Instruments will be two The combination is one (the same is true for Audi's previously released laser headlight system). And to make existing laws make concessions, automakers must prove the safety of new technologies in a variety of ways. In the future, when you are driving on the road, if there is a car on the fast lane that is particularly slow, you may be able to use this lighting system to signal the “Leave Fast Lane!†on the road. But the most attractive part of Texas Instruments' system is probably that you don't have to worry about being attacked by the "Large Dog" when driving at night!
Electric dc motors were the
first type widely used, since they could be powered from existing
direct-current lighting power distribution systems. A electric Dc Motor's speed can be controlled over a wide range, using either a variable supply
voltage or by changing the strength of current in its field windings. Small electric dc motor are used in tools, toys, and appliances. The universal motor
can operate on direct current but is a lightweight motor used for portable
power tools and appliances. Larger electric dc motor are used
in propulsion of electric vehicles, elevator and hoists, or in drives for steel
rolling mills.
Areas of application: the electric dc motor rotor part of the armature iron core, armature, commutator, such as equipment, electric dc motor is suitable for most electronic products, such as electric screwdriver, laser, smart home, gas valve, etc
Applications:
Method of use: the best stable in
horizontal plane, installed on theelectric dc motor output
shaft parts, cannot use a hammer to knock, knock prone to press into the electric
dc motor drive, may cause damage to internal components, and cannot be
used in the case of blocked.
Operating
temperature range:
Electric dc motor should be used at a temperature of -10~60℃.
The figures stated
in the catalog specifications are based on use at ordinary room
temperature catalog specifications re based on use at ordinary room
temperature (approximately20~25℃.
If a electric dc motor is used outside the prescribed temperature range,the grease on the gearhead
area will become unable to function normally and the motor will become unable
to start.Depending on the temperature conditions ,it may be possible to deal
with them by changing the grease of the motor's parts.Please feel free to
consult with us about this.
Storage
temperature range:
Electric dc motor should be stored ta a temperature of -15~65℃.
In case of storage
outside this range,the grease on the gearhead area will become unable to
function normally and the motor will become unable to start.
Service life:
The longevity of
geared motors is greatly affected by the load conditions , the mode of
operation,the environment of use ,etc.Therefore,it is necessary to check the
conditions under which the product will actually be used .The following
conditions will have a negative effect on longevity.Please consult with us
should any of them apply.
