Compared with incandescent lamps, fluorescent lamps, metal halide lamps, halogen lamps, high-pressure sodium lamps, and low-pressure sodium lamps, LED lighting is a new lighting technology. The advantages of LED lighting are high light efficiency, no harmful substances, and long life. For example, the flux of 60w incandescent bulb is generally only 480lm-600lm, and 5W/6W LED bulb can be completely replaced, saving 10 times of electricity than incandescent lamp. Incandescent lamp use time is generally only - hours, LED light bulb 25,000 hours are general requirements. More importantly, LED bulb light does not use glass, and all accessories are environmentally friendly. As the technology matures and costs decrease, LED lights will eventually replace the traditional lighting market.
Some Terms You Need to Know About LED Lighting
1. Color rendering
The degree to which the light of LED lamp presents the color of the object itself is called color rendering, which is the degree of color fidelity. The color rendering of LED lights is represented by the color rendering index, the color rendering index represents the color deviation of LED lights from standard light (sunlight) when illuminating an object, and can more fully reflect the color characteristics of LED lamps. LED lights with high color rendering have better color performance, and the colors we see are close to natural colors. LED lights with low color rendering have poor color performance, and the color deviations we see are also larger. The International Commission of Illumination (CIE) sets the color rendering index of the sun as Ra100. The color rendering index of various light sources is different, such as: high pressure sodium lamp color rendering index&#;Ra=23, fluorescent tube color rendering index &#;Ra=60~90, LED lamps color rendering index Ra=70~95.
There are two types of color rendering: &#;&#;&#;&#;
Faithful color rendering: to correctly express the original color of the substance, the color rendering index (high Ra&#;light source, the value is close to Ra100&#;, the best color rendering).&#;&#;&#;&#;&#;
Effect color rendering: To clearly emphasize a specific color, you can use additive color to enhance the color rendering effect to express the beautiful life.
The principle of choosing the color rendering index of LED lights: In order to increase the brightness of outdoor lights, choose LED lights with a color rendering index greater than Ra70. For home lighting and general lighting applications, choosing LED lights with a color rendering index greater than Ra80 can meet the needs. Museum lighting and display lighting are special. They need to restore the true colors of objects, so you need to choose LED lights with a color rendering index greater than Ra95.
2. Color temperature
Expressed in absolute temperature K, that is heating a standard black body, when the temperature rises to a certain degree, the color starts to change from dark red-light red-orange red-white-blue. When the color of the light of LED light fixtures and the black body are the same, we call the absolute temperature of the black body at that time the color temperature of the light of LED light fixtures. Since the correlated color temperature is an evaluation value of the light color performance of LED lamps when the black body radiation is close to the light color of LED lamps. It is not an accurate color contrast. Therefore, different LED ligh bulbs with the same color temperature may have slight differences in the appearance of light colors. However, the color temperature alone cannot determine the color rendering ability of LED light lamps or the degree of color rendering of the object under LED light lamps.
Color temperature of LED lights below K: The light color is reddish, giving people a warm feeling and a stable atmosphere.
-K color temperature of LED lights: people have no obvious visual psychological effects at this color temperature, and they have a refreshing feeling, which is also called neutral color temperature.
Color temperature of LED lights above K: The light color is bluish, giving people a cool feeling.
The choice of color temperature and brightness about LED lighting:
under high color temperature LED light, if the brightness is too low, it will give people a gloomy atmosphere; under low color temperature LED light, if the brightness is too high, it will give people a sultry feeling.
Using two LED light fixtures with a large color temperature difference in the same space, while obtaining brightness, the color temperature layering effect is very good.
The conventional color temperatures of LED lights on the market are mainly K, K, K, K, K.
3. Light efficiency
An important indicator to measure the energy saving of a LED light is the luminous flux emitted by the LED light divided by the credit consumed by the light source, unit: lm/W. The higher luminous efficiency value, the stronger ability of LED light to convert electrical energy into light energy, which means that LED light is more energy-saving when LED lights provide the same brightness. Under the same power, the brightness of LED light is higher.
4. Luminous flux
The unit is lumens (lm), and all the radiant energy emitted by a LED lamp and perceived by the human eye is called luminous flux. We can understand it as the sum of light energy emitted by the LED lamp. It play a guiding role when we replacing traditional lights. For example, if the flux of fluorescent light is 500lm, then we can use about 500lm LED lamp to replace.
5.Luminosity
The illuminance produced by a luminous flux of 1lm (lumens) evenly distributed on a surface of 1 square meter, in lux (lux, lx). The illuminance has a relationship with the light emitting angle and distance. When we use LED lamp to design lighting, lux is a commonly used indicator. For example, the illuminance of the warehouse needs 50lux and the office countertop needs 200-300lux.

Traffic Signal lights are controlling and signaling devices placed on the road intersections, pedestrians crossing, and other places to guide, warn and control the flow of traffic of vehicles, bicycles, pedestrians, and other road users. LED Trafficlight is a signal light that directs traffic operations, generally consisting of red lights, green lights, and yellow lights. A red light means no passage, a green light means passage is permitted, and a yellow light means a warning. LED traffic lights are divided into motor vehicle signal lights, non-motor vehicle signal lights, pedestrian crossing lights, direction indicator lights (arrow lights), lane lights, flashing warning lights, road and railway level crossing lights.
