Difference between downlight and spotlight: 1, ceiling opening
General household downlights have three opening sizes: 2 ",2.5" and 3 ". The larger the opening size, the higher the overall height of the downlight, and the greater the requirements for the depth of your ceiling. Generally speaking, the height of downlight after stretching is between 10 cm and 13 cm, so the ceiling depth of downlight is generally above 13 cm. If the ceiling is too shallow, the ceiling installation of ceiling spotlights only needs 6 to 8 cm.
The difference between downlight and spotlight: 2. light source
From the light source, downlights can be equipped with incandescent bulbs and energy-saving lamps. Yellow when incandescent lamps are installed. When installing energy-saving lamps, the type of bulbs can be white or yellow. Because the number of downlights at home is generally large, considering the energy saving problem, energy-saving lamps are generally installed in downlights. Now there are miniature energy-saving lamps specially made for downlights on the market. The shape of energy-saving lamps can be divided into two types: 2U tube and spiral tube, and the wattage types are 3W, 5W, 7W and 9W. In addition, the downlight is fixed and its light source direction cannot be adjusted, while the light source direction of spotlight can be changed.
The difference between downlight and spotlight: 3. Light efficiency requirements.
The downlight uses energy-saving lamps inside, with white light and yellow light to choose from. Diffuse light source does not concentrate light and its temperature is low. Therefore, it is mainly used for lighting, and the angle of light source cannot be adjusted. Generally used in aisles, bedrooms and living rooms. The spotlights used in home decoration are divided into embedded spotlights and exposed spotlights, which are generally used in living rooms, bedrooms, TV background walls, wine cabinets, shoe cabinets and so on.
The difference between downlight and spotlight: 4. price
From the price point of view, spotlights are more expensive in the same class. Generally speaking, the domestic brands of downlight spotlights with better quality are Opal, Sanxiong Aurora, NVC, Ye Song and Li San. Among them, Ye Song's NVC and Sanxiong Aurora have the best cost performance. There are generally three types of downlights: large (5 inches), medium (4 inches) and small (2.5 inches). At present, the market price is between 25- 15 yuan, 28-32 yuan, and 36-48 yuan. Of course, the above prices do not include light sources. There are two types of downlights: horizontal plug and vertical plug, and the price of horizontal plug is a little more expensive than vertical plug (even if it is the same material).
The difference between downlight and spotlight: 5. danger
Generally speaking, downlights are safer than spotlights. Generally speaking, you can't use spotlights to illuminate woolen fabrics at close range, and you can't have flammable obstacles at close range, otherwise it will easily cause fires. Downlight won't have much consideration in this respect.
What kind of light sources are commonly used for downlights?
LED backlight is the development trend of light source of light box in the future. Other LED fluorescent lamps with light strips are not effective, and light spots and dark areas will appear. LED backlight belongs to surface light source, and the irradiation surface is uniform. Mainly divided into outdoor and indoor lamps, including street lamps, floodlights, tunnels, wall washing lamps, landscape lamps, trail lamps and strip lamps. A single LED light source can be used as outdoor decorative lights, such as building lighting, square lighting and other indoor lamps: fluorescent lamps, spotlights, downlights, bubble lamps, strip lamps, ceiling lamps, bold lamps, table lamps and so on.

It is mainly used for special lighting, such as emphasizing a place with great taste or originality.
Distinguishing method between downlight and spotlight
1, look at the light source
When an incandescent lamp is installed, it is a yellow light; When installing the energy-saving lamp, it can be white light or yellow light, and the light source direction of the ceiling downlight cannot be adjusted. General household spotlights use quartz bulbs or beads. Of course, quartz bulbs are not necessary for large spotlights. Quartz bulbs only have yellow light. Moreover, the light source direction of general spotlights can be adjusted freely.
2. Look at the application location
Downlights are generally installed in the ceiling, and the ceiling needs to be more than150 mm. Of course, downlights are also external. It is a good choice to install downlights in areas without ceiling lamps or chandeliers. The light is softer than spotlights. Spotlight can generally be divided into track type, point hanging type and embedded type. Spotlights are generally equipped with transformers, and some are without transformers. Embedded spotlights can be installed on the ceiling. Spotlights are mainly used in places that need to be emphasized or expressed, such as TV walls, hanging pictures, ornaments and so on. , can play a rhyming role and enhance the effect.
Step 3 look at the price

What is downlight and its characteristics?
Downlight is a downward lighting lamp embedded in the ceiling. Its biggest feature is that it can maintain the overall unity and perfection of architectural decoration, and will not destroy the perfect unity of ceiling art because of the setting of lamps and lanterns. Its structural advantages are that the light source is hidden inside the building decoration, the light source is not exposed, there is no glare, and the visual effect is soft and uniform. Generally used in hotels, families and cafes.
From the light source emission direction, downlight belongs to directional lighting lamps, and only its reverse side can receive light. The beam angle belongs to the spotlight, with concentrated light and strong contrast between light and shade. The illuminated object is more prominent and brighter, setting off a quiet environment. Generally applicable to supermarkets, office buildings and business halls.

The LED ceiling lamp has good monochromaticity. The common colors are red, green, yellow and orange, which are mainly changed by changing the current. The color change of LED downlights is mainly to see what lights are inside. If you want yellow light, you have to install incandescent lamps. If you want to have white light, you have to install energy-saving lamps, and the direction of the light source cannot be adjusted.
What's the difference between a downlight and a spotlight?
The light of the spotlight is directional, and the direction of the spotlight can be adjusted, but it will not reach far, and the light is soft. For example, it can be used to partially illuminate the TV wall to contrast the atmosphere at night, and it can also be used to decorate the porch, which looks less dazzling. Generally, the light source of downlight can illuminate any place in the room, with soft light, but simple color and no directionality. Downlight is widely used, and now all major shopping malls will see the decoration of downlight. In contrast, spotlights are more expensive.

2. The LED downlight is the latest one, which can be used as a substitute for the ordinary downlight. The light is better than the ordinary one. The only disadvantage is that if it is broken, the 1 2 lamp cannot be replaced.
3. There are many kinds of materials for tube lampshades, such as iron surface, pure aluminum and die casting. Generally speaking, iron surface tube lamps are cheap, while pure aluminum and die casting materials are more expensive, but they are more durable. Iron-faced downlights are widely used in engineering, but it is suggested that downlights in home decoration use a cover that is not easy to rust.
The lamp cap of downlight is an important part, and the main material of the lamp cap is ceramics. The reed inside is the most important, there are two kinds of copper and aluminum. Good brands are made of aluminum, and a spring is installed under the contact to strengthen contact. The other is the power cord of the lamp holder. Good brands use three wires to connect lamp holders (three wires are live wire, zero wire and ground wire), and some of them will have terminals, which is also a very basic way to distinguish good brands from ordinary brands. Reflective cups are generally sand cups and light cups, made of aluminum, which will not change color and have better reflectivity. Some small manufacturers will use plastic spraying to do it. This new process looks good, but it will become dark or even black after a while. The identification method is to look at the uniformity of the cut. Aluminum is cut neatly, but plastic spraying is the opposite.
characteristic
1, compact and high luminous flux. The power consumption of energy-saving lamps is 1/5 of that of incandescent lamps, but their service life is six times that of incandescent lamps. Keep the compact design of 175, restrain the existence of lamps and create a bright space.
