LED light is a new type of lighting product. Its full name is "LightEmittingDiode", which means "light-emitting diode". LED lights have the characteristics of high efficiency, energy saving, long life and no pollution, so they are widely used in outdoor lighting, indoor lighting, automotive lighting and other fields.
The principle of LED lights
The light-emitting principle of LED lights is to produce light through electronic transitions in semiconductor materials. This light is monochromatic and can be obtained without a color filter. Red, green, blue and other different colors of light. Compared with traditional incandescent lamps, LED lamps have higher light efficiency, longer life and lower energy consumption.
Application fields of LED lights
LED lights have a wide range of applications, including:
1. Indoor lighting: LED lights can be used in homes and offices The brightness and color effects of lighting in places such as shopping malls and shopping malls are better than traditional incandescent lamps.
2. Outdoor lighting: LED lights can be used for lighting in street lights, billboards, landscape lighting and other places. Their energy-saving effect and lifespan are better than traditional fluorescent lights.
3. Automotive lighting: LED lights can be used in car headlights, taillights, turn signals and other parts, and their brightness and lifespan are better than traditional car lights.
Operation steps of LED lights
1. Prepare LED lights and power supply.
2. Plug the LED light into the power socket.
3. Turn on the power switch and the LED light will glow.
4. If you need to adjust the brightness and color effect of the LED light, you can use a dimmer or remote control to adjust it.
Spotlights are different from ordinary wall-mounted lamps, ceiling fans, and floor lamps. On the one hand, this kind of spotlight may be more suitable for the field of advertising. For example, spotlights can be seen on outdoor billboards, and the colors and specifications of the spotlights are different, and the power can also be changed according to later needs. So how to choose specifically? What are the corresponding specifications and sizes of various spotlights? Through the following, I believe we can have an in-depth analysis of this, and from this we can also know the appropriate specifications of spotlights. If you choose appropriately, It can achieve the effect of both beauty and practicality in many aspects.
1. Spotlight specifications
1. Spotlights are mostly used to enhance the lighting of decorations, usually Embedded in suspended ceilings or walls, the equipment will generally emit higher temperatures when working, so be sure to purchase high-quality products, otherwise there will be safety hazards. The size of spotlights generally increases as the wattage increases. Generally, the opening of 3W is between 60MM-85MM, and it will continue to increase as the wattage increases. 2. There are many differences in the specifications of household spotlights. Among them, the sizes of 35w LED spotlights are: 205*90*h170PAR refers to the parabolic reflective lamp, which refers to the shape.
20, 30, 38 repre sent the maximum outer diameter size. For example, for 38, the maximum outer diameter is (1/8)*38*25.4≈120.0mm. 38 is measured in cents. The conversion relationship is as follows: 1 cent = 1/8 inch, 1 inch = 25.4 mm, MR16 GU10 and GU10 are commonly used spotlight cup connectors, and LEDs are also marked in this way. 3. In appearance, the plug of MR16 has two thin pins, and the plug of GU10 has two round pins. MR16 is a low-voltage lamp, usually the voltage is 12V, and GU10 is a high-voltage lamp, usually the voltage is 110V or 220V. MR: multi-faceted reflection (light cup), the number behind indicates the diameter of the lamp cup (unit is 1/8 inch), the diameter of MR16=16×1/8=2 inches≈50mm, the diameter of MR11=11×1/8=2 Inches≈35mm.
GU: G indicates that the lamp head type is plug-in, U indicates that the lamp head part is U-shaped, and the following digits indicate the center distance of the lamp pin holes (unit is mm), LED spotlight series introduction - PAR, MR16, GU10. The above is a detailed introduction to the specifications of spotlights. I hope it will help everyone have a more specific understanding of the specifications of spotlights.
2. Distinguish between downlights and spotlights.
1. From the light source point of view, downlights can be equipped with incandescent bulbs or energy-saving lamps. When an incandescent lamp is installed, the light is yellow. When installing energy-saving lamps, depending on the type of bulb, it can be white light or yellow light. The light source direction of the ceiling downlight cannot be adjusted.
Generally, household spotlights use quartz bulbs or lamp beads. Of course, large spotlights do not necessarily use quartz bulbs. Quartz bulbs only have yellow light.
And the light source direction of general spotlights can be freely adjusted.
2. From the application position, downlights are generally installed in the ceiling. Generally, the suspended ceiling needs to be above 150mm before it can be installed. Of course, there are also external downlights. It is a good choice to install downlights in areas without ceiling lights or chandeliers. The light should be softer than spotlights.
Spotlights can generally be divided into track type, point-hung type and built-in type. Spotlights generally come with a transformer, but there are also ones without a transformer. Recessed spotlights can be installed in the ceiling. Spotlights are mainly used for places that need to be emphasized or expre ssed, such as TV walls, hanging paintings, accessories, etc. They can create aura to enhance the effect.
3. From the price point of view, the price difference between the two is not big. The 3W ones on the market are generally about 20 yuan, but only about 10 yuan on Taobao. The price of ultra-thin downlights released in the past year is about 20 yuan. It is a little more expensive, usually twice as much as the original downlight, but its light source is more durable than the original, and its size is also developing in the direction of ultra-thin
< p> The above article recommends a common lamp, that is, a spotlight. The analysis of its size and specifications has been covered. From this, we can know that in one aspect, it is not very different from ordinary ceiling lamps and floor lamps. Similarly, the design of spotlights is relatively special and is more suitable for use in the field of publicity. For example, when installed around outdoor billboards, it can not only achieve basic lighting purposes, but also create a more dreamy atmosphere according to color changes and brightness adjustments. And the romantic effect, you might as well refer to the above for further analysis. What we explain to you is the recommendations on the size and specifications of spotlights and the pre cautions during the purchase and matching process.
