How to choose different kinds of lamps and lanterns?
The lighting in the market is colorful and dazzling, and the decoration style and consumption situation of consumers are different. In order to better help you choose more satisfactory lighting and create the decoration effect you want, the editor of the topic divides the lighting into crystal lamps, ceiling lamps, light strips, downlight spotlights, wall lamps, table lamps according to the style of lighting. , chandeliers, floor lamps, etc. to explain their prices and purchasing skills.
Look at the electroplating process: to see if there is foaming, yellowing, blackening, exposed bottom, electroplating pitting, the same color has color difference, if the requirements are strict, it is to see whether there are teardrops on the surface.
Look at the crystal grade: lead oxide is 24% or more to be called crystal. Crystal materials generally include domestic ordinary machine grinding, domestic semi-handmade, domestically handmade, domestic imitation imported, Egyptian crystal, Swarovski crystal. The best domestic K9 crystal material is generally used in the Chinese market, which is a domestic A-grade crystal.
Look at crystal accessories: good crystal accessories are the same color as the lamp holder, and the color retention period is the same as that of the lamp holder.
Look at the crystal appearance: the appearance is crystal clear. There are no streaks, bubbles, water ripples and impurities in the lamp bead material. The cut is precise and symmetrical, the cut surface is smooth and polished, and the sparkle is bright. The hole size of the pendant is the same, smooth and flawless, and the shape of the lamp bead is the same size.
Space: If it is used as a light source in the living room, astigmatism or comprehensive lighting should be selected; the dining room should choose the downward projection lighting method; the bedroom light source needs to be soft, and astigmatic lighting can be used.
Size: If the lighting area is about 15 square meters, then the diameter of the ceiling lamp is 40cm; if the lighting area is 20-35 square meters, it is more appropriate to choose the diameter of 60-70cm for the ceiling lamp.
Look at the quality of FPC: FPC is divided into two types: copper-clad and rolled copper. The copper foil of the copper-clad plate is protruding. If you look closely, you can see it from the connection between the pad and the FPC. The rolled copper is closely integrated with the FPC, and can be bent arbitrarily without the phenomenon of pad falling off.
Look at the accessories: Regular LED light strips will be accompanied by instructions for use and light strip specifications in the box, and will also be equipped with LED light strip connectors or card holders.
Spotlight purchase: There are two types of spotlights: crystal lamp and bull's eye lamp, and the bull's eye lamp can be rotated. The transformer should first disassemble the outer casing of the transformer to see the size of the circuit board and coil inside. If the circuit board is large, the arrangement of components should be thinner to enhance heat dissipation. The size of the coil determines the brightness and life of the spotlight. The purchase of lamp cups mainly depends on the filament. High-quality lamp cups adopt a vertical structure, while ordinary lamp cups adopt a horizontal structure.
Light brightness: Generally speaking, it is better to have soft light, and the degree should be less than 60 watts. In addition, different types of wall lamps should be selected according to the installation needs. For example, if the room is small, use a single-head wall lamp; if the room is large, use a double-head wall lamp; if the space is large, you can choose a thicker wall lamp; otherwise, choose a thinner wall lamp. . The last thing to note is that it is best to choose a wall lamp with a protective cover for the bulb.
Luminosity: For the direct-illuminated floor lamp, it should be noted that the lower edge of the lampshade is preferably lower than the eyes, so that the eyes will not feel uncomfortable due to the irradiation of the bulb. In addition, if the indoor light contrast is too large, it will increase the load on the eyes, so try to choose a floor lamp that can be dimmed.
Color light: Please buy a desk lamp with a yellowish white light, not a desk lamp with a blue and white light.
Power: Generally speaking, the power of fluorescent lamps can meet the requirements of desktop reading and writing lighting between 9W and 18W.
Color temperature: As an eye protection desk lamp, the color temperature is between 5000-5500K, which is suitable for the light environment that our eyes need for vision.
Height: As an eye protection table lamp, it cannot be too high or too low, and the suitable range is between 35-50cm.
Running performance: First, turn the fan head by hand, and listen carefully to the sound of the fan head when it is running. It is better to be light and even. If the electronic governor is selected, the operation and observation time should be longer under the condition of low voltage output to see if there is any phenomenon such as heat generation and vibration.
Crystal chandeliers
Now the market is basically selling crystal lamps made of artificial crystal glass. Artificial crystal glass, that is, adding 24% lead oxide to ordinary glass (the composition is silicon dioxide). The higher the lead content, the higher the brightness and transparency of the artificial crystal glass.
Look at the crystal grade: lead oxide is 24% or more to be called crystal. Crystal materials generally include domestic ordinary machine grinding, domestic semi-handmade, domestically handmade, domestic imitation imported, Egyptian crystal, Swarovski crystal. The best domestic K9 crystal material is generally used in the Chinese market, which is a domestic A-grade crystal.
Look at the crystal appearance: the appearance is crystal clear. There are no streaks, bubbles, water ripples and impurities in the lamp bead material. The cut is precise and symmetrical, the cut surface is smooth and polished, and the sparkle is bright. The hole size of the pendant is the same, smooth and flawless, and the shape of the lamp bead is the same size.
ceiling lamp
Purchase: The selection of ceiling lamps should be based on the style of the functional space, and choose different shapes and materials of ceiling lamps to decorate the space. High-quality ceiling lamp materials have smooth and uniform edges and corners, burrs and seams, uniform plating and spraying, and uniform brightness and color of electroplating accessories. Generally speaking, the greater the power, the greater the luminous flux and the greater the brightness. A good light source is bright, with moderate color temperature, good color rendering, an average lifespan of more than one year, high light efficiency, and small stroboscopic.
Size: If the lighting area is about 15 square meters, then the diameter of the ceiling lamp is 40cm; if the lighting area is 20-35 square meters, it is more appropriate to choose the diameter of 60-70cm for the ceiling lamp.
light strip
Look at the solder joints: The LED light strips produced by regular LED light strip manufacturers are produced by SMT patch process, solder paste and reflow soldering process. Therefore, the solder joints on the LED strip are relatively smooth and the amount of solder is not much.Look at the quality of FPC: FPC is divided into two types: copper-clad and rolled copper. The copper foil of the copper-clad plate is protruding. If you look closely, you can see it from the connection between the pad and the FPC. The rolled copper is closely integrated with the FPC, and can be bent arbitrarily without the phenomenon of pad falling off.
downlight spotlight
Downlight purchase: The material of the panel is recommended to be die-cast aluminum, aluminum or stainless steel. The color of die-casting aluminum downlights is mainly sand-sweeping nickel, and the colors of aluminum downlights are more diverse, mainly including sand gold, sand silver and sand black, while stainless steel is mainly the natural color. The main material of the lamp head is ceramic, and the good brand of reed inside is made of aluminum. Reflective cups are generally of two types: sand cups and light cups. The material is aluminum, which will not change color, and the reflectivity is better.
wall lamp
Lampshade quality: The lampshade mainly depends on whether its light transmittance is suitable, and the pattern and color of the surface should echo with the overall style of the room. Whether the corrosion resistance of the metal is good, and whether the color and luster are bright and full are important indicators for checking the quality.
floor lamp
Height: Consider the height of the ceiling. If the ceiling is too low, the light can only be concentrated in a local area, which will make people feel that the light is too bright and not soft enough. Also pay attention to the use of top-lit floor lamps. The ceiling in the home is preferably white or light-colored, and the material of the ceiling should have a certain reflective effect.Luminosity: For the direct-illuminated floor lamp, it should be noted that the lower edge of the lampshade is preferably lower than the eyes, so that the eyes will not feel uncomfortable due to the irradiation of the bulb. In addition, if the indoor light contrast is too large, it will increase the load on the eyes, so try to choose a floor lamp that can be dimmed.
desk lamp
Flicker-free: "Flicker-free" is the minimum condition for fluorescent eye protection lamps. Commercially available fluorescent eye protection lamps generally come with a flicker test gyro. When the top is rotated under the light, the border of the top presents a clear and stable pattern.Color light: Please buy a desk lamp with a yellowish white light, not a desk lamp with a blue and white light.
Power: Generally speaking, the power of fluorescent lamps can meet the requirements of desktop reading and writing lighting between 9W and 18W.
Color temperature: As an eye protection desk lamp, the color temperature is between 5000-5500K, which is suitable for the light environment that our eyes need for vision.
Height: As an eye protection table lamp, it cannot be too high or too low, and the suitable range is between 35-50cm.
ceiling fan light
Motor form: divided into shaded pole type and capacitive type. Capacitive motors are more common and have the characteristics of large starting torque and low power consumption, but the cost is slightly higher. However, considering the long-term interests, it is better to choose a capacitive motor.Running performance: First, turn the fan head by hand, and listen carefully to the sound of the fan head when it is running. It is better to be light and even. If the electronic governor is selected, the operation and observation time should be longer under the condition of low voltage output to see if there is any phenomenon such as heat generation and vibration.
