First, we need to observe major Cast light 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 Cast light 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.
fixed major Cast light There are many methods, such as ceiling, embedded, hoisting (straight pipe or chain) and wall absorption. Generally, open lamps are usually used indoors. Enamel surface reflector shall be selected, with thick aluminum oxide film or aluminum reflector coated with silicon dioxide protective film. Movable local illuminators are equipped with corresponding handles, hooks, clamps, etc. Fixed local illuminators are usually firmly locked on the working machine by screws or fixing mechanisms. For large factories and large machine tool places requiring separate lighting major Cast light Reflectors made of materials with strong light control characteristics, such as prismatic glass, mirror glass and polished aluminum, to obtain narrow beam distribution.
The working voltage of a single bulb for LED tunnel lighting is very low, about 3V, so the power consumption of a low-voltage working environment is half of the power required for the same strong light. The tunnel lamp has a long service life and does not need regular maintenance and inspection. After a period of use, the traditional major Cast light The brightness of the tunnel lamp will be greatly reduced, but its attenuation is only 20% of that of the tunnel lamp. Moreover, the tunnel lamp is small in size and can be made into various shapes to adapt to various environments. The shell of the tunnel lamp is of integrated design, which is durable and not easy to be damaged. Each light source inside can be installed and removed separately, which is very convenient in the future maintenance process, and the overall design can ensure good heat dissipation effect. The heat dissipation rack inside the shell, the airflow and the heat emitted by the full contact with the air, effectively reduce the major Cast light And prolongs the service life of the tunnel lamp.
The bulb shall be firm and upright and shall not be loose or skewed. If the enamel umbrella is corroded or deformed major Cast light It needs to be replaced in time. Before using electric tools, please check whether the wiring, plug, socket, grounding and leakage protection devices are in good condition. Do not use them if they are damaged. Safety slogans, warning signs and safety operation instruction boards shall be set up on the construction site. Materials on the site shall be stacked orderly and stably and handled from top to bottom. When using hand-held electric tools, please wear personal protective equipment and the power cord should be empty. It is forbidden for non operators to use it on site major Cast light Power switches, wires and various mechanical equipment. Outdoor construction is not allowed in rainy season. Outdoor construction should be carried out after the rain is dry. The Quality Safety Department is responsible for preparing labor protection articles to ensure the safety of construction personnel.
During use, the bulb will be hit by wind and rain, which may cause its angle deviation, thus affecting the lighting effect. If any deviation is found, it must be adjusted in time. Check the bulb surface regularly. If on major Cast light Cracks found on the surface glass of the bulb may cause rainwater to enter the bulb, which will seriously affect the use effect and service life of the bulb. The bulb should be removed immediately and sent to the original factory for repair. Avoid all kinds of serious accidents, such as leakage. Clean the lamp regularly to maintain its brightness. Turn off the lamp before cleaning it major Cast light The power supply of the lamp shall be cleaned with a dry cloth or dry cloth to prevent the lamp from being damp, let alone with chemical or corrosive substances. Otherwise, the bulb will be corroded, which may cause accidents.
1. LED fluorescent lamp has high luminous efficiency, low heat generation and good color rendering. Traditional lamps generate a lot of heat energy, while LED lamps convert all electric energy into light energy, avoiding energy waste and saving energy. two major Cast light Mercury free, environmentally friendly, UV free. Traditional fluorescent lamps use low-pressure mercury vapor to radiate ultraviolet light in the discharge process, so that the phosphor emits visible light. 3. LED fluorescent lamp has soft light, eye protection, no noise and quick start. Traditional fluorescent lamps use AC power, so 100-120 stroboscopic lamps are generated per second. 4. LED fluorescent lamp voltage can be adjusted from 80V to 245V. Traditional fluorescent lamps are lit by the high voltage released by the rectifier, but cannot be lit when the voltage drops. five major Cast light Energy saving and power saving, long service life. The power consumption of LED fluorescent lamp is less than one third of that of traditional fluorescent lamp, and its service life is ten times of that of traditional fluorescent lamp. It can be used for a long time without replacement, thus reducing labor costs. 6. It is safe and reliable with good shockproof effect. LED lamp body is made of epoxy resin rather than traditional glass, which is more solid and reliable.
