LED downlight basics

The downlight generally has a screw base that can be directly fitted with incandescent or energy-saving lamps. The downlight is a type of lighting fixture that is embedded in the ceiling and is light-emitting. Its greatest feature is to maintain the overall unity and perfection of the architectural decoration, and will not destroy the perfect unity of the ceiling art because of the installation of the lamps. This invisible luminaire embedded in the ceiling, all light is projected downwards and is a direct light distribution. Different reflectors, lenses, blinds, and bulbs can be used to achieve different lighting effects. The downlight does not take up space, which can increase the soft atmosphere of the space. If you want to create a warm feeling, try to install multiple downlights to reduce the pressure on the space. Generally used in hotels, homes, and cafes.
Downlight introduction
Downlights are available in both mounted and concealed
The description of the downlight is also a kind of downlight, but unlike the downlight, it is more decorative.
Downlights are generally large (5 inches) medium (4 inches) small (2.5 inches) three. The price of the small market is between 20-15 yuan, the medium is between 28-32 yuan, and the large size is between 36-48 yuan. Of course, the above prices do not contain light sources. There are two kinds of downlights: horizontal insertion and vertical insertion. The price of horizontal insertion is a little more expensive than vertical insertion. From the application position, the downlights are generally installed in the ceiling. Generally, the ceiling needs to be installed above 150mm. Of course, the downlights are also external. It is a good choice to install a downlight in the area without a ceiling or chandelier, and the light is softer than the spotlight.
Suitable places for downlights: large offices, conference rooms, department stores and specialty stores, laboratories, airports and some residential homes.
Downlight classification:
1. According to the installation method: embedded downlights and surface mounted downlights.
2, according to the installation method of the lamp: spiral lamp head and plug lamp head, vertical downlight and horizontal downlight.
3, according to the location: home downlights and engineering downlights.
4. According to the number of light sources: single insertion lamp and double insertion lamp.
5, according to the anti-fog situation of the light source: ordinary downlights and anti-fog downlights.
6, by size: 2 inches; 2.5 inches; 3 inches; 3.5 inches; 4 inches; 5, 6, 8, 10 inches.
Inch refers to the inch, which refers to the diameter of the reflector inside.
7, according to the type of light source: ordinary downlights and LED downlights .
Using the downlight to make the lamp, the installation is easy, does not occupy the place, generous and durable, usually no problem for more than five years, the style is not easy to change. The price is also cheap
Downlight material:
1. The general household downlight does not exceed 2.5 inches, and 5W energy-saving lamps can be placed.
2, LED downlights are only available in recent generations, can be used as a substitute for ordinary downlights, light is better than ordinary, the only drawback is that if the fault is 1, 2 lights can not be replaced.
3, downlight cover material is also divided into a variety of materials, iron, pure aluminum, die-casting and other materials, in general, iron-faced downlights are cheap, pure aluminum and die-casting materials are more expensive, but more durable. There are a lot of iron lamps used in the project, but it is recommended that the downlights for home decoration use a cover that is not easy to rust.
The downlight head is a more important part. The main material of the lamp head is ceramic. The reeds inside are the most important. There are two kinds of copper and aluminum. The good brand is made of aluminum, and the spring is installed under the contact point to enhance the contact. In addition, it is the power cord of the lamp holder. A good brand uses a three-wire wiring lamp head (three wires are fire wire, spirit wire, ground wire), and some will have terminal terminals. This is also a very basic method to distinguish good brands from ordinary brands.
Reflective cups are generally two kinds of sand cups and light cups. The material is aluminum, the aluminum material will not change color, and the reflection degree is better. Some small manufacturers will use plastic spray to do it. This new process looks good, but it will darken or even darken over time. The method of identification is to look at the uniformity of the cut, the aluminum is cut very neatly, and the spray is the opposite.
characteristic
1. Compact and high luminous flux. The energy-saving lamp is one-fifth of the incandescent lamp, the life is six times that of the incandescent lamp, and the size maintains a compact design of 175, which suppresses the presence of the lamp and creates a bright space.
2. Two kinds of reflectors with mirror and frosted. A glittering specular reflector that blends the frosted reflector of the ceiling with moderate brilliance.
3. The sliding fixed card is adopted, which is convenient for construction. It can be installed on ceilings of different thicknesses from 3mm to 25mm, which can be easily removed during maintenance.
4, energy-saving lamps have three color temperatures to choose from. There are 2700k (yellow light), 4000k (neutral light), 6700k
Three types of (white light), these three color temperatures can create a different atmosphere. The most suitable color tube can be selected according to different purposes.
Downlight safety
The main problem of the downlight of the downlight is on the lamp socket. Some of the lamps of the branded downlight are not resistant to high temperature and are easily deformed, which may cause the bulb to not be screwed down. Now, all lamps can only be sold after 3C certification, and consumers should choose 3C-certified downlights.
Another is that the thickness of the panel is important, which determines the price of a downlight.
The difference between spotlights and downlights
Many people are confused about downlights and spotlights. I don't know the difference between these two types of lights, where to apply them to the home, and how the effects of the applications are different.
Simply put, a downlight is a luminaire that is more concentrating than a conventionally mounted luminaire, typically for general or auxiliary lighting.
A spotlight is a highly concentrated luminaire that emits light with a specific target. Mainly used for special lighting, such as highlighting a very flavorful or very innovative place.
We distinguish between downlights and spotlights from these aspects.
1. From the light source, the downlight can be equipped with an incandescent bulb or an energy-saving lamp. When the incandescent lamp is installed, it is yellow. When the energy saving lamp is installed, the light bulb type may be white light or yellow light. The direction of the light source of the downlight is not adjustable.
From the picture below, we can directly see the energy-saving lamps of the downlights, while the anti-fog downlights are equipped with a waterproof glass cover.
Generally, household spotlights use quartz bulbs or lamp beads. Of course, large spotlights do not necessarily use quartz bulbs. Quartz bulbs are generally only equipped with yellow light.
Moreover, the direction of the light source of the general spotlight can be adjusted freely.
2. The downlights are generally installed in the ceiling from the application position. Generally, the ceiling needs to be installed above 120mm. Of course, the downlights are also external. It is a good choice to install a downlight in the area without a ceiling or chandelier, and the light is softer than the spotlight.
Spotlights can generally be divided into orbital, point-and-hung and in-line. Spotlights usually have transformers, but there are also transformers. The built-in spotlights can be mounted in the ceiling. Spotlights are mainly used for places that need to be emphasized or expressed, such as video walls, paintings, ornaments, etc., which can be used to enhance the effect.
3, from the price point of view the same grade, spotlights are more expensive.
Generally speaking, the domestic brands with better quality downlights include Op, Sanxiong, Aurora, NVC, Songye and Sanli. Among them, NVC and Sanxiong Aurora, Songye is the best value for money.
Downlights are generally large (5 inches) medium (4 inches) small (2.5 inches) three. The current market price of the trumpet is between 25-15 yuan, the medium is between 28-32 yuan, and the large size is between 36-48 yuan. Of course, the above prices do not contain light sources. There are two kinds of downlights: horizontal insertion and vertical insertion. The horizontal insertion price is a little more expensive than the vertical insertion (also the same material).
It should be noted that spotlights are generally not used for close-range illumination of wool fabrics, and there is also a flammable barrier at close range, which may cause fire. Although the spotlight consumes a lot of power, it has a great effect in its proper position. The spotlights and the colorful light cups are decorated to have a different flavor.
