- ★Rights protection proposal
Lighting is one of the most frequently used electrical products in the family. The quality supervision organization will generally check the marking, structure, internal wiring of external wiring box, grounding regulations, anti-shock protection, heat-resistant and fire-resistant, and electric mark of lighting products. Experts suggest that these six aspects are the best starting point for consumer rights protection, and the goal of rights protection is easy to achieve.
- Common problems with markup:
- No complete items are marked as required, and the lamp model is incorrectly indicated; no maximum power is marked in the correct way, no type of light source is marked, no sign or warning is given; the standard is out of date or has been abolished, etc.
- Common structural problems:
- The cut of elbow of pendant lamp and wall lamp, and the conductor frame of fluorescent lamp bracket have sharp edges, which easily cut the insulating layer of the conductor and cause electric shock danger. On some barrel lamp, the terminal seat is usually not fixed, which makes the creeping distance and electrical gap between the live parts and the metal shell not meet the requirements; the used terminals do not meet the requirements; the insulating liner and sleeve are not suitable; The fixing of the tube is unreliable, easy to loosen or shift; the connection between the lamp holder and the catheter is not firm and easy to loosen.
- Common problems with external and internal wiring:
- There is no conductor fixture, or the conductor fixture is not part of the fixture fixed on the lamp or a part of the lamp; the conductor fixture does not match the size of the conductor to be clamped, and the conductor is loose; some desk lamps fix the power cord with a cover.
- Common problems in grounding regulations:
- The grounding device is not fixed on the lamp permanently and reliably; on some circular ceiling lamps, the chassis is sprayed with paint, and the paint of the grounding part is not removed when grounding, resulting in unqualified results.
- Common problems in protection against electric shock:
- There are usually two kinds of unqualified anti-shock situations. One is that the live parts of ordinary lamps are easily touched during or after the installation of bulbs. The other is some ring-shaped ceiling lamps with electronic ballasts. The terminals of electronic ballasts do not meet the requirements. When the lamps are turned on, the live parts are easily touched.
- Common problems in heat resistance, fire resistance and electric trace resistance
- Insulating materials with fixed live parts in place are not flame retardant or high temperature resistant. Fixed live parts in lamps and lanterns generally have power line terminal, ballast terminal, electronic ballast output terminal, lamp holder, fluorescent lamp holder lamp holder, some ballast shell, non-ceramic lamp holder and other components.
- ★ Quality expectation
- Lamps include chandeliers, ceiling lamps, wall lamps, barrel lamps, spotlights, etc. Their main functions are illumination. Different space functions are different, and the light needed is also different. Over-bright or over-dark lamps not only affect the beauty, but also harm human health. Lighting is not only an indispensable indoor lighting equipment, but also a very important decoration.
- The survey found that the coordination of color and interior furniture, wall and floor color is the first consideration for young people to choose ideal lamps. The light and color of lamps and lanterns should be in harmony with the color of the interior wall. The wall is in cold tone, and the incandescent lamp with warm tone can play a coordinating role. If it is in hot summer, or in a small room, the use of fluorescent lamps can make people feel comfortable, quiet and bright and spacious. The surface color of lamps and lanterns should be in harmony with the interior curtains, furniture and other colors, so as to make the interior decoration form a perfect artistic whole. In addition, fashion people choose lamps and lanterns, will be combined with the overall design of the room to consider. If the overall design of the room is biased towards the classical, then choose all kinds of lamps and lanterns with national tradition, such as archaic Palace lights, plum blossoms and decorative patterns such as landscape paintings, auspicious animals, etc. If the overall design of the room is biased towards lively and lively, with modern style, you can choose all kinds of lamps and lanterns with concise lines and geometric patterns in the modelling, such as room ratio. More magnificent, you can choose imitation gold plating lampshade and engraved gold-spun glass lampshade to foil.
Experts recommend that you do not install the wrong lamps, which is more harmful. The main manifestations are: first, light radiation and light pollution. In order to achieve the effect of bright lights, the installation of large and small lamps or lamps with very high brightness will cause certain harm to the human body, because the lamps will also produce certain light radiation, resulting in dizziness, insomnia, depression and other adverse reactions; second, the disorder of lights endangers visual acuity. Lighting color disorder, will be a trance before the eyes, because the pupil has a certain regulatory limitations, long-term face of colorful lights, vision will be damaged to varying degrees, serious or even affect the brain central nervous system; third, direct light has dazzling damage.
If the lighting in the home is too bright, or long-term direct light, it will make people tired and unable to concentrate. Based on these problems, consumers must pay attention to these three parameters when purchasing LED lamps: first, color temperature. Color temperature decides the color of cold and warm light. The lower the temperature, the warmer the lamp color temperature will affect vision health and sleep quality. The second is light flux. The luminous flux determines the intensity of light; the third is the color rendering index. It is the ability of color to restore the true color of an object.
