ANIMATED PEDESTRIAN COUNTDOWN TRAFFIC LIGHT
LED TRAFFIC LIGHT
Push buttons are installed at traffic lights with a dedicated pedestrian signal, and are used to bring up the pedestrian “walk” indication in locations where they function correctly. Push buttons do provide confirmation feedback and pedestrians are more likely to wait for the “walk” indications before passing thru the road.
The push buttons not only meet the needs of road users, they can also be adapted to suit the individual requirements of intersections in a city. They help pedestrians, cyclists and people with visual impairments to cross light-controlled road crossings safely.

Indoor or interior lighting
Indoor lighting for a building is the light source that is being integrated into the inner of the building for some general purpose such as brighten the room and give some special or desired effect to the room. The lighting in a home will changes the mood of person in the room just as it does the perceived size of a room. The lighting in a room either provides illumination for the entirety of the room, it highlights very specific elements. Fixture, placement and type of lighting are all the important aspects of indoor design, and they work in conjunction with color selections, size, availability of natural light and furniture selection. The elements that come together when the right lighting is achieved and this can transform a room into a seamless combination of functionality and style.
How indoor lighting affect us
There is a lots of research says that the effect of indoor light has on our emotional system. This is because the light will being perceived as heat, and the perception of heat can trigger our emotions. Beside that, indoor lighting regulates a lot of human behaviors and activities such as sleep and attentiveness. Research have state that students who study in environments with the natural day lighting can increase in their academic performance. Natural light is always preferred but not always attainable in a classroom or work environment. So, indoor light have affect us in our daily light, we need to be more careful when dealing with the purchasing and installation of indoor light.
A parabolic aluminized reflector lamp (also PARCAN light, PARcan, or simply PAR) is a type of electric lamp that is widely used in commercial, residential, and transportation illumination. Usage includes locomotive headlamps, aircraft landing lights, and residential and commercial recessed lights ("cans" in the United States). They are identical in principle to sealed beam automobile headlights.
This article covers only their use in stage lighting. The lamps and their fixtures are widely used in theatre, concerts and motion picture production when a substantial amount of flat lighting is required for a scene.
In situations where sunlight or other specular light is available, a white foam reflector is often used to accomplish the same effect as a PAR array.
PAR cans are being replaced in some applications by LED PAR cans, which use less electric power and produce a wide array of saturated colors without the use of color filters, when white light is not needed.
PAR lights are often used in theatrical or live music shows. Commonly they are used to generate colours by fitting them with colored sheets called gels. The cans are arranged into rows of different colours and identical rows placed on different sides of the stage. Due to their affordability, they are ideal for colour washes in several different colours. However, because of the lack of control over the beam diameter, shape and sharpness, PARs are rarely used as front of house lights other than for front washes but can be used for special effect lighting such as lighting from directly above or from extreme angles as well as general wash lights overhead/above stage. If used cleverly, par cans can provide low budget productions with good effects.
Indoor Lighting Technology Trend In Fourth Industry Revolution
1) Connectivity–With LEDs comprehensively in the mainstream, the next frontier in lighting is controls. Call it smart, call it connected, call it what you like – the point is that your lights can be controlled. Controller and sensors have been around for donkey’s years, but the challenge now is to make them more sophisticated, get them to communicate with other devices and make sure people use them to perform more and more task.
2) The internet of things (IoT)-There are only computer , smart-phone and other smart device can be connected to web. With the internet of things(IoT) technology, it’s no longer just computers and smart-phones that are connected to the web, but also your clothes, your coffee cup, your heart monitor and your LED lights. Lighting is an ideal network for internet-of-things services to be built on – because it’s already there in the ceiling of every building, looking down at us, wired up and ready to go. You only have to add a few sensors or controller so that it can make some data connection with other user.
3) Built-in light sources–Because LED light sources have good quality, so it don’t have to be replaced very often, and because no standards have emerged for what they should be like, manufacturers have got used to building them into fittings, rather than designing new luminaires around replaceable ‘lamps’. But what happens if they fail early? Or a better, more efficient module comes on the market? Organisations such as Zhaga have sought to address the issue by coming up with agreed designs, but integrated modules are becoming the norm. Will we regret lumbering our clients with light sources they can’t change?
