Lighting brand ceiling lamp room
LED to shoot the light, English name is LED spotlights, it is the most popular energy conservation and environmental protection products, with more and more of lamps and lanterns made of LED as light source, one of the most acclaimed is LED to shoot the light, as compared with other LED lamps, LED lamp price is lower.LED lamp is mainly used for decoration, commercial space, lighting and building lighting, etc., with the development and progress of LED technology, the market of LED lamp performance advantage is very outstanding, high purity aluminum reflector, the beam is the most accurate and reflective effect is best;Symmetrical light distribution systems such as narrow Angle, wide Angle and asymmetric etc., and the projector lamp is equipped with a scale plate, people can adjust the radiation Angle conveniently according to the scale.In addition, in order to facilitate maintenance, the LED projector lamp is replaced by a back-up switch.The lighting decoration effect is first-rate, and the LED projection lamp can realize the dynamic effects of gradual change, jumping, color flashing, random flashing, gradual change, chase and scanning.
1. LED spotlights can be driven by low-voltage direct current: it has the advantages of small load and weak interference, and has low requirements on the use environment.2. LED spotlights can control the composition of the luminous spectrum well, so that they can be well used for local or key lighting in museums and exhibition halls.
3. The luminous directivity of LED spotlights is very strong: the luminance attenuation is much lower than that of traditional light sources, and the price of LED spotlights is fairly civilian.
4. The response time of LED spotlights is very fast: at the microsecond level, as long as the switch is on, it will be on immediately without any delay or flicker.
5. The light energy concentration of LED spotlights is very high: it is concentrated in a small wavelength window with high purity.
6. The service life is very long, generally between 50,000 and 100,000 hours, because LED is a semiconductor device, and even frequent switching will not affect the service life.
7. Good environmental protection, LED to shoot the light in the process of production don't add "mercury", also do not need air, do not need glass shell, good impact resistance, good shock resistance, invulnerability to breakage and facilitate transportation, very green, known as "green energy", the LED lamp price.
8. Energy saving, the spectrum of LED spotlights is almost all concentrated in the visible light frequency band, and its luminous efficiency can reach 80 ~ 90%.It is generally believed that the energy-saving of energy-saving lamps 4/5 is a great innovation, but LED spotlights are more than 1/2 energy efficient than energy-saving lamps, which is a greater reform of solid light sources.

1. In large stores, purchase products with the “Three Guarantees†commitment and purchase lamps with the CCC certification mark.
2. Look for three when shopping. A look at the product logo is complete, the regular product logo is often more standardized, should identify: trademark and factory name, product model specifications, rated voltage, rated frequency, rated power. Second, see if the lamp power cord has a CCC safety certification mark, and the external conductor cross-sectional area should be ≥ 0.75mm2. Third, look at whether the lamp charged body is exposed. After the light source is installed in the lamp holder, the finger should not touch the live metal lamp holder.
3. Choose a higher type of protection against electric shock: According to the type of protection against electric shock, ceiling lamps can be classified into 0, I, II and III categories. The safety of Type 0 lamps is poor. Type I, Type II and Type III lamps should be purchased as far as possible.
Type 0 lamps rely on basic insulation as protection against electric shock. In case of basic insulation failure, it is easy to generate electric shock hazard.
The protection against electric shock of Type I lamps not only depends on the basic insulation, but also includes additional safety measures. That is, the easy-to-reach conductive parts are connected to the grounding protection wires so that the easily accessible conductive parts will not be electrified when the basic insulation fails.
Type I lamps have a ground symbol next to the grounding terminal. It should be noted that the metal shell of Type I lamps should be effectively grounded. If the lamp replacement can touch the ballast, the ballast should also be effectively grounded.
The protection against electric shock of Type II lamps not only depends on the basic insulation, but also has additional safety measures, such as double insulation or reinforced insulation. In case of basic insulation failure, it can also rely on supplementary insulation protection. Lamps in plastic enclosures are generally Type 0 or Type II. It is best to purchase Type II lamps. Type II lamps have symbols.
The protection against electric shock of Class III lamps depends on the power supply being a safety extra-low voltage, and no voltage exceeding the safety extra-low voltage is generated inside the lamp.
4 using the light instructions:
1 After buying the lamps and lanterns, do not install them first. You should look carefully at the markings on the lamps and read the installation instructions. Install the lamps in accordance with the instructions in the manual. Use the lamps according to the rules in the manual.
2 According to the light source parameters provided by the sign to replace the aging lamp in time, it is found that both ends of the lamp are red, and the lamp should be replaced in time to prevent the ballast from being burned and other unsafe phenomena.
3 During cleaning and maintenance, care should be taken not to change the structure of the lamp or to replace the parts of the lamp. After the cleaning and maintenance is over, the lamp should be installed as it is. Do not miss or replace the parts of the lamp. 
Fixed ceiling lamps are often used in homes, offices, entertainment venues and other places. When purchasing, they should first consider the safety and quality of the lamps, and consider the size, height, and function of the room.
