LED fluorescent lamp PC lampshade
LED fluorescent lamp PC lampshadeLED fluorescent lamp PC lampshade is a kind of LED fluorescent lamp accessories. It is to better gather the light and make the light more concentrated. Heat resistance and cold resistance; also has the advantages of self-extinguishing, flame retardant, non-toxic, colorable and so on.
Chinese name LED fluorescent lamp PC lampshade is used for LED fluorescent lamp. Road light gathering material polycarbonate

effect
The PC lampshade of LED fluorescent lamp is not only covered on the lamp in order to make the light gather together, it can also prevent electric shock, and it also has an effect on protecting the eyes. The main role of the milky white lampshade is to make the light softer and more evenly diverge into the space without causing dazzling conditions. Protect your eyes and make the lamps more suitable for their function. And the light transmittance must be within a certain range, so that the light energy cannot be wasted too much in the cover, and the light can be scattered to each space through the film layer, which can not see the internal lamp beads, but also maximize the light Divide out.
material
Polycarbonate is a thermoplastic resin containing — [ORO-CO] —link in the main chain of the molecule. According to the different ester groups in the molecular structure, it can be divided into aliphatic, alicyclic, and aliphatic-aromatic types. The value is aromatic polycarbonate, and bisphenol A polycarbonate is the most important, and the molecular weight is usually 30,000 to 100,000. Polycarbonate, English name Polycarbonate, referred to as PC. PC is an amorphous, odorless, non-toxic, highly transparent colorless or slightly yellow thermoplastic engineering plastic with excellent physical and mechanical properties, especially excellent impact resistance, high tensile strength, bending strength, and compressive strength; Small creep, stable size; good heat resistance and low temperature resistance, stable mechanical properties, dimensional stability, electrical properties and flame retardancy in a wide temperature range, can be in -60 ~ 120 ℃ Long-term use; no obvious melting point, in the molten state at 220-230 ℃; due to the rigidity of the molecular chain, the viscosity of the resin melt is large; the water absorption rate is small, the shrinkage rate is small, the dimensional accuracy is high, the dimensional stability is good, the film permeability is small ; Self-extinguishing material; stable to light, but not resistant to ultraviolet light, good weather resistance; resistant to oil, acid, strong alkali, oxidizing acids and amines, ketones, soluble in chlorinated hydrocarbons and aromatic solvents It is easy to cause hydrolysis and cracking in water for a long time. The disadvantage is that due to poor fatigue resistance, stress cracking is easy to occur, poor solvent resistance, and poor wear resistance.
Features
1. With high light transmission, high diffusion, no glare, no light shadow;
2. The light source has excellent concealment (effectively adjust the diffusion rate and light transmittance, and the light transmittance reaches the maximum without seeing the lamp beads);
3. The light transmittance reaches 94%;
4. Has high flame resistance;
5. Has high impact strength;
6. Suitable for the use of LED bulbs;
7. Achieve the conversion of point light emission into spherical light emission.
PC lampshade selection
The replacement of the lampshade is relatively fast, and most of the lamps are carefully designed by the designer. For the lamp, it is not necessary to replace the entire lamp, only the external lampshade of the lamp needs to be replaced. Therefore, it is a good choice to change the environment to replace the lampshade.
First of all, let ’s first understand the decorative effects brought by different materials of the lampshade. The lampshade on the cloth gives a simple and elegant impression. The lampshade on paper can create a hazy and dreamy atmosphere. The lampshade made of metal has a cool tone. Temperament and modernity, and the drum-shaped lampshade brings nostalgic feelings. In the bedroom, we can choose silk lampshades, especially hand-sewn and hand-drawn lampshades, which can bring softness to the room and add intimacy; the living room can choose linen or parchment lampshades.
Secondly, you only need to pay attention to the color. The white lampshade has good light penetration and can be matched with the crystal base to create a crystal clear effect; black and color are relatively poor in light penetration. Some can radiate the light downward, so that the local light is stronger, and can be matched with the bronze base.
Finally, choose the lampshade according to the shape of the lamp holder. If the lamp holder is curved, then the lampshade should choose a curve style. If the lamp holder is flat and straight, choose a more regular lampshade. If the lamp holder looks Thick, you can choose a conical lampshade to reduce this sense of weight. After using the lampshade for a period of time, it is not only covered by dust, but also the long-term exposure of the light, causing the color to fall off. We can use these small methods to clean the lampshade in the details to extend the life of the lampshade.
