How to buy LED energy saving lamp:
1, LED brightness (LM) is different, the price is different. LED for LED lamps should meet the laser class Ⅰ standard.
2, anti-static ability Antistatic ability LED, long life, and thus high prices. Usually anti-static greater than 700V LED can be used for LED lighting.
3, the same wavelength of the LED, the same color, such as the requirements of the same color, the price is high. Producers who do not have LED spectrophotograms are hard to produce purely color products.
4, leakage current LED is a one-way conductive light, if there is reverse current, known as leakage, leakage current LED, short life, low prices.
5, the use of different angles LED light angle is not the same. Special light angle, the price is higher. Such as full diffuse angle, the price is higher.
6, the quality of life is the key to the quality of life, life by the decay of light. Light fades small, long life, long life, high prices.
7, wafer LED luminous body for the wafer, different chips, the price difference is very large. Japan, the United States of the chip more expensive, generally Taiwan and domestic chip prices lower than Japan, the United States (CREE).
8, the size of the chip chip size to the side length, large chip LED quality is better than the small chip. The price is proportional to the size of the chip.
9, colloidal colloidal LED colloid is generally an epoxy resin, plus anti-ultraviolet and fire retardant LED more expensive, high-quality outdoor LED lighting should be anti-ultraviolet and fire. Each product will have a different design, different designs for different purposes, LED lighting reliability design includes: electrical safety, fire safety, environmental safety, mechanical safety, health and safety, safe use of time and other factors. From the electrical safety point of view, should be consistent with the relevant international and national standards.
1, Energy saving. White LED energy consumption is only 1/10 of incandescent, energy-saving lamps 1/4.
2, Longevity. Life of up to 100,000 hours or more, the ordinary family lighting can be described as "once and for all".
3, Can work in high-speed state. Energy-saving lamps if the frequent start or turn off the filament will be black quickly broken.
4, Solid-state packaging, are cold light source type. So it is very convenient to transport and install, can be installed in any miniature and closed equipment, not afraid of vibration, basically do not need to consider cooling.
5, LED technology is changing with each passing day, its luminous efficiency is striking breakthrough, the price is also constantly reduced. A white LED into the family era is coming quickly.
6, Environmental protection, no mercury harmful substances. LED bulb assembly parts can be very easy to disassemble, no manufacturers can be recycled through other people.
7, With light technology to LED point light source for the surface light source, increase the luminous surface, eliminate glare, sublimation visual effects, to eliminate visual fatigue;
8, Lens and shade integrated design. Lens at the same time with the role of light and protection, to avoid duplication of light waste, so that more simple and beautiful products;
9, High-power LED flat cluster packaging, and radiator and lampholder integrated design. Fully protect the LED cooling requirements and service life, from the fundamental to meet the LED lighting structure and shape of any design, highly distinctive features of LED lamps;
10, Significant energy saving. Using ultra-bright high-power LED light source, with high efficiency power supply, more than 80% energy saving than traditional incandescent, the same power brightness is 10 times the incandescent;
11, Long life of 50,000 hours or more, more than 50 times the traditional tungsten lamp. LED using a highly reliable advanced packaging process - eutectic welding, full protection of LED long life;
12, No strobe. Pure DC work, eliminating the traditional light strobe caused by visual fatigue;
13, Green. Does not contain lead, mercury and other pollution elements, the environment without any pollution;
14, Impact resistance, strong resistance to lightning, no UV (UV) and infrared (IR) radiation. No filament and glass shell, no traditional tube fragmentation problem, no harm to the human body, no radiation.
15, Low thermal voltage work, safe and reliable. Surface temperature ≤ 60 ℃ (ambient temperature Ta = 25 ℃);
16, Wide voltage range, the global common. 85V ~ 264VAC full voltage range constant current, to ensure that life and brightness are not affected by voltage fluctuations;
17, The use of PWM constant current technology, high efficiency, low heat, constant current accuracy;
18,To reduce line losses, no pollution to the grid. Power factor ≥ 0.9, harmonic distortion ≤ 20%, EMI in line with global targets, reducing the power supply line power loss and to avoid the high-frequency interference on the power grid pollution;
19, Universal standard lamp, can be directly replace the existing halogen, incandescent, fluorescent;
20, Luminous efficiency can be as high as 801m / w, a variety of color temperature optional, high color rendering index, good color;
