With the emergence of high brightness white LED light source, it is possible to apply it in the lighting field. According to the prediction of international authoritative organizations, the 21st century will enter the era of new light sources represented by LED, that is, the fourth generation of new light sources. major Square lamp Courtyard lamp Its brightness is the same as that of traditional fluorescent lamps, and its color is gentle and easy to accept. The service life is 50000-80000 hours. When the bulb is started, it will open immediately and can be repaired when it is damaged (the traditional fluorescent lamp has been damaged and cannot be reused). It is not only very energy-saving, but also more environmentally friendly. major Square lamp Courtyard lamp It is one of the main products promoted by the national green lighting energy-saving project, and is currently the first choice to replace the traditional high-pressure sodium lamp for industrial and mining lamps. At present, LED mining lamp has been used in many industrial enterprises, and its application effect is well received by customers.

(1) High light efficiency: the spectrum is almost all concentrated on the visible light frequency, and the efficiency can reach 80% - 90%. (2) High light quality: because there is no ultraviolet and infrared ray in the spectrum, there is no heat and radiation. This is a typical green light source. (3) Long life: the standard life is 40000 hours when the luminous flux decays to 70%. major Square lamp Courtyard lamp It can be used for 8 years under normal conditions. (4) Reliable and durable: there is no tungsten wire, glass and other easily damaged parts, the abnormal scrap rate is very small, and the maintenance cost is very low. (5) Flexible application: small size, flat packaging, easy to develop into light, thin, short products, can be made into various forms of dot, line, surface special products. (6) Green environmental protection: waste can be recycled without pollution, major Square lamp Courtyard lamp And unlike high-pressure mercury lamps, they contain mercury. (7) Very short response time: energy-saving ceiling lamp suitable for frequent switching and high-frequency operation.

First, we need to observe major Square lamp Courtyard lamp The workmanship of the mask and its luminous effect. This depends on how much light the bulb lamp shade emits to the light source. When viewing the mask, you can view its shape, whether the light transmittance and thickness of the bulb are the same, and check the approximate blur of the mask. We need to see if the material of the bulb is suitable for heat conduction. You can test in the field. After working for several minutes, observe whether there is odor above the bulb when the temperature rises. After that, we will also check the lamp body temperature after the power is turned off. The lower the temperature, the better. ordinary major Square lamp Courtyard lamp It will change due to the change of ambient temperature. When selecting bulb lamp, you need to check its color temperature. Generally speaking, the color temperature should not be too high or too low as long as it can meet the normal household lighting needs.

The power supply of LED project lights is high-voltage alternating current. During installation, please keep away from the place that is easy to access, and properly ground the lamps to avoid electric shock accidents. When wiring, the installation personnel shall select the appropriate power line according to the power of the bulb actually used, and separate the power supply to avoid affecting the normal use of flood lights. major Square lamp Courtyard lamp It is designed to be waterproof and moisture-proof, and its protection grade can reach IP65. It can withstand the test of rain, but cannot work underwater, and its protection level cannot meet the requirements of underwater work. major Square lamp Courtyard lamp The installation position of shall be able to bear the weight of the projection lamp, and its bearing capacity shall be 10 times greater than the weight of the projection lamp, so that the lamp can be firmly installed and the danger of falling in the future can be avoided.
