1. Energy saving: The energy consumption of white LEDs is only 1/10 of that of incandescent lamps and 1/4 of energy-saving lamps.
2, longevity: life of up to 100,000 hours or more, for ordinary home lighting can be described as "one and every time."
3, can work in a high-speed state: If the energy-saving lamp is frequently started or turned off, the filament will be black, soon broken, so more secure.
4, solid-state package, is a cold light source type. So it is well transported and installed and can be installed in any miniature and enclosed equipment without fear of vibration.
5, led technology is advancing with each passing day, its luminous efficiency is making an amazing breakthrough, the price is constantly reduced. The era of a white LED entering the home is rapidly coming.
6, environmental protection, no mercury harmful substances. The assembled parts of the LED light bulb can be easily dismantled and can be recycled by other people without factory recycling.
7, light distribution technology allows LED point light source to expand into a surface light source, increase the light emitting surface, eliminate glare, sublimate visual effects, eliminate visual fatigue.
8, lens and lampshade integrated design. The lens has the function of concentrating and protecting at the same time, avoiding the repeated waste of light and making the product more concise and beautiful.
9, high-power led planar package, and radiator and lamp holder integrated design. Fully protected the led heat dissipation requirements and service life, fundamentally meet the LED lamp structure and shape of any design, with the distinctive features of LED lamps.
10, significant energy savings. Ultra-bright high-power led light source, with high-efficiency power supply, saving more than 80% than traditional incandescent lamps, the same power is 10 times the brightness of incandescent lamps.
11. Over 50,000 hours of long life, more than 50 times that of traditional tungsten lamps. LED uses a highly reliable advanced packaging process - eutectic welding, to fully protect the LED's long life.
12, no flicker. The pure DC work eliminates the visual fatigue caused by the traditional light source strobing.
13, green. Does not contain lead, mercury and other pollution elements, without any pollution to the environment.
14, impact resistance, strong resistance to lightning, no ultraviolet (UV) and infrared (IR) radiation. No filaments and glass enclosures, no fragmentation of the traditional lamp, no harm to the human body, no radiation.
15, work under low heat voltage, safe and reliable. Surface temperature ≤ 60°C (ambient temperature Ta = 25°C).
16, wide voltage range, global LED lights. 85V ~ 264VAC full voltage range constant current, to ensure that life and brightness from voltage fluctuations.
17, using PWM constant current technology, high efficiency, low heat, high precision constant current.
18, reduce the loss of the line, no pollution to the power grid. Power factor ≥ 0.9, harmonic distortion ≤ 20%, EMI in line with global indicators, reducing power consumption of power lines and avoiding high-frequency interference pollution on the power grid.
19. Universal standard lamp holder can directly replace existing halogen lamps, incandescent lamps and fluorescent lamps.
20, luminous efficiency as high as 80lm / w, a variety of LED lamp color temperature, high color rendering index, good color rendering.
According to the general household lighting power density to choose, the size of the study, the choice of led lights are also different in general according to 1.5 to 3 watts per square meter to reference, led light higher light efficiency, you can choose 1.5 to 2 watts per square M to reference, if you do the study, the brightness can be appropriately higher, choose 2 watts per square meter of led light is best.
For example, your study is 10 square meters, then your study led light use 2*10=20 watts of led lights.
1, led bulb long service life. In general, the led bulbs are very long compared to other general lamps and can reach 50,000 hours of use.
2, led light bulb can adapt to various conditions of the environment, the general energy-saving lamps if it is in the frequent opening and closing state is very easy to bad, and led light bulbs can adapt to this high state of the work environment.
3, led light bulb production, fusion of the world's most advanced light production technology, its light source is a surface light source, this light source can increase the light emitting surface, very affinity with people's eyes.
4. There is no mercury, lead and other harmful substances inside the led bulb, and it has no pollution to the environment.
1, the same lighting places, such as bedroom, living room, kitchen and bathroom lighting requirements are not the same, the most appropriate LED lighting color temperature range, should be close to the natural color temperature range of the sun is the most scientific choice.
2, the light is not whiter the better, the high color temperature of the light is close to the glare of the sun at noon, the eye stimulation is too strong, but the low color temperature is prone to fatigue, only the color temperature and comfortable lighting is a healthy light, this we have the naked eye Can be observed.
3, and then look at the next purchase of LED lamps are strobe, strobe lamps have an impact on vision. Healthy LED lights eliminate streaks by using a constant-power, constant-current drive technology. Strobe is a problem that is difficult to detect with the naked eye. There is a small method that can be used to photograph the camera with the light. If the screen is flickering, there is a fault and frame skipping.
A look at packaging and trademarks
The national mandatory requirements LED lighting manufacturer's products on the packaging marked the following: rated voltage, voltage range, rated power, rated frequency. Generally speaking, the trademark of high-quality products is of good quality and printed with clear characters and is not easy to fall off. Wipe with soft and damp cloth, the mark is clearly legible, it is not easy to wipe off, and there are manufacturers' trademarks and related certification marks. Fake and shoddy products have poor print quality, fuzzy fonts, and are easily erased. There are no manufacturer's trademarks and related certification marks.
Second look at the appearance of LED lamps
The real LED energy-saving lamp is a three-color tube, white tube, covered by hand to see, more white. In addition, from the lamp point of view, more than one lamp can be put together to compare the better shape and size of the lamp tube are mostly machine bending forming, mostly large-scale production of products. Product consistency is good, quality is easier to ensure, and interchangeability during maintenance is better. Of course, there must not be cracks, looseness, and traces of cracks in the interface. In the process of installation and dismantling, there should be no loosening of the lamp head and a smashing phenomenon.
The plastic shell of the lamp must be selected as the kind of engineering plastic flame retardant. Ordinary plastics are easily deformed and flammable, and are prohibited from being used in the production of energy-saving lamps. From the surface, it is easy to distinguish between the two. The latter surface is smooth and shiny, and the former has a frosted glass-like texture.
Three to see the temperature at work
LED energy-saving lamps under normal operating conditions, the temperature rise should be very low. Otherwise, the life span of LED energy-saving lamps is very short. At the same time, when the energy-saving lamp is lit, there is rapid flashing, or it is very dazzling, indicating that the energy-saving lamp has quality problems.
Four look start performance
LED energy-saving lamps start with two characteristics: First, the higher the temperature is easier to start; Second, the light is turned off, will not flash. In addition, it is worth mentioning that many LED energy-saving lamps are very dark, which is unfavorable for lamp life. LED energy-saving lamps should have power circuits and PCB boards inside.
Five to see the interference situation
In China, electromagnetic compatibility is a project that electrical appliances must pass. However, this project is very complex. When users buy lights, they look at the package to see if they have passed the national electromagnetic compatibility test. Second, they use a medium- and short-wave radio. When the lights are working, put the radio in the vicinity. The lower the noise is, the lower the noise is emitted at the medium and short wave radio stations, the better the electromagnetic compatibility of the lamp under test.
