First, LED energy-saving lamp introduction:
LED energy-saving lamp is a high-brightness white light-emitting diode light source, high light efficiency, low power consumption, long life, easy to control, maintenance-free, safe and environmentally friendly; It is a new generation of solid cold light source, soft light color, colorful, colorful, low loss, low energy consumption, green environmental protection, suitable for families, shopping malls, banks, hospitals, hotels, restaurants and other public places for a long time.
1. High efficiency and energy saving: only a few degrees of electricity are consumed in a thousand hours (ordinary 60W incandescent lamps consume 1 kWh of electricity in 17 hours, ordinary 10W energy-saving lamps consume 1 kWh of electricity in 100 hours)
2. Ultra-long life: semiconductor chips emit light, no filament, no glass bubbles, not afraid of vibration, not easy to break, service life up to 50,000 hours (ordinary incandescent lamps have a service life of only 1,000 hours, and ordinary energy-saving lamps have a service life of only 8,000
hours)
3. Health: light healthy light does not contain ultraviolet and infrared rays, does not produce radiation (ordinary lights contain ultraviolet and infrared) 4, green environmental protection: does not contain mercury and xenon and other harmful elements, conducive to recycling, and will not produce electromagnetic interference (ordinary lamps contain elements such as mercury and lead, and the electronic ballast in energy-saving lamps will
produce electromagnetic interference)
5.
Protect eyesight: DC drive, No strobe (ordinary lamps are AC driven, it will inevitably produce strobe) 6, high light efficiency: small heating, 90% of electrical energy into visible light (80% of ordinary incandescent lamps into heat energy, only 20% of electrical energy into light energy)
7, high safety factor: the required voltage, current is small,
heat generation is small, no safety hazards, in mines and other dangerous places

Second, the disadvantages of LED energy-saving lamps compared with ordinary energy-saving lamps:

1. LED energy-saving lamps will have the same strobe phenomenon as ordinary incandescent lamps under AC drive, while ordinary energy-saving lamps have no strobe phenomenon. Strobe can strain the eyes easily.
2. The light of each LED bulb is too bright, which will strongly stimulate the eyes, not to look directly, even for a short time, while ordinary energy-saving lamps are relatively softer!
3. The irradiation angle is limited, generally only 120 °, while ordinary energy-saving lamps can almost irradiate 360 °
4, the brightness of the irradiated room is not better than energy-saving lamps, because the LED only has high brightness in the narrow angle of direct viewing, and the light weakens rapidly after deviating from the angle. Therefore, the advantages of LED energy-saving lamps as indoor lighting fixtures may not be more obvious than ordinary energy-saving
lamps, but they are still very excellent when used as torches, desk lamps, spotlights and other lamps that only need to irradiate narrow angles.

Third, how to choose LED energy-saving lamps:
1. LED brightness (MCD) is different and the price is different. The LED used for LED lamps should meet the laser level I class standard
2, antistatic ability Antistatic ability strong antistatic ability LED, long life, so the price is high. Usually antistatic more than 700V LED can be used for LED lighting
3, wavelength consistent LED, color consistency, if the color is required to be consistent, the price is high. It is difficult for manufacturers without LED spectrophotometers to produce products with pure colors
4, leakage current LED is a unidirectional luminescence, if there is a reverse current, it is called leakage, LED with large leakage current, short life, low

price 5. LEDs with different luminous angles have different luminous angles. Special angle of luminescence, higher price. If the full diffuse angle is full, the price is higher.
6. The key to different qualities of life is life, and life is determined by light decay. Small light decay, long life, long life, high price.
7. The emitter of the wafer LED is a wafer, and the price of different wafers varies greatly. Chips in Japan and the United States are more expensive, generally the price of Taiwanese and domestic chips is lower than that of Japan and the United States (CREE)
8, the size of the wafer is indicated by the side length, and the quality of the large chip LED is better than that of the small chip. The price is proportional to the size of the wafer.
9. The colloidal body of ordinary LED is generally epoxy resin, and the LED with anti-ultraviolet and fireproof agent is more expensive, and high-quality outdoor LED lighting should be anti-ultraviolet and fireproof.
Each product will have different designs, different designs are suitable for different uses, the reliability design of LED lighting includes: electrical safety, fire safety, applicable
environmental safety, mechanical safety, health safety, safe use time and other factors. From the perspective of electrical safety, it should comply with relevant international and national standards.

一、LED节能灯简介：
　LED节能灯是用高亮度白色发光二极管发光源，光效高、耗电少，寿命长、易控制、免维护、安全环保；是新一代固体冷光源，光色柔和、艳丽、丰富多彩、低损耗、低能耗，绿色环保，适用家庭，商场，银行，医院，宾馆，饭店他各种公共场所长时间照明。
1、高效节能：一千小时仅耗几度电（普通60W白炽灯十七小时耗1度电，普通10W节能灯一百小时耗1度电）
2、超长寿命：半导体芯片发光，无灯丝，无玻璃泡，不怕震动，不易破碎，使用寿命可达五万小时（普通白炽灯使用寿命仅有一千
小时，普通节能灯使用寿命也只有八千小时）
3、健康：光线健康光线中不含紫外线和红外线，不产生辐射（普通灯光线中含有紫外线和红外线）
4、绿色环保：不含汞和氙等有害元素，利于回收，而且不会产生电磁干扰（普通灯管中含有汞和铅等元素，节能灯中的电子镇器会
产生电磁干扰）
5、保护视力：直流驱动，无频闪（普通灯都是交流驱动，就必然产生频闪）
6、光效率高：发热小，90%的电能转化为可见光（普通白炽灯80%的电能转化为热能，仅有20%电能转化为光能）
7、安全系数高：所需电压、电流较小，发热较小，不产生安全隐患，于矿场等危险场所

二、led节能灯比起普通节能灯的缺点：

1、LED节能灯在交流电驱动下和普通白炽灯一样会有频闪现象，而普通节能灯没有频闪现象。频闪会使眼睛容易疲劳。
2、每个LED灯泡的光线过亮，会强烈刺激眼睛，不可直视，哪怕短时间，而普通节能灯相对要柔和些！
3、照射角度有限制，一般只能照射120°，而普通节能灯几乎可照射360°
4、照射房间的亮度并不比节能灯出色，因为LED只在直视的狭小角度内有高亮度，而偏离该角度后光线迅速减弱。因此，LED节能
灯作为室内照明灯具的优势未必比普通节能灯明显，但作为电筒、台灯、射灯等只需照射狭小角度的灯具使用时还是非常优秀的。

三、如何选购LED节能灯：
1、LED亮度（MCD）不同，价格不同。用于LED灯具的LED应符合雷射等级Ⅰ类标准
2、抗静电能力抗静电能力强的LED，寿命长，因而价格高。通常抗静电大于700V的LED才能用于LED灯饰
3、波长一致的LED，颜色一致，如要求颜色一致，则价格高。没有LED分光分色仪的生产商很难生产色彩纯正的产品
4、漏电电流LED是单向导电的发光体，如果有反向电流，则称为漏电，漏电电流大的LED，寿命短，价格低

5、发光角度用途不同的LED其发光角度不一样。特殊的发光角度，价格较高。如全漫射角，价格较高。
6、寿命不同品质的关键是寿命，寿命由光衰决定。光衰小、寿命长，寿命长，价格高。
7、晶片LED的发光体为晶片，不同的晶片，价格差异很大。日本、美国的晶片较贵，一般台湾及国产的晶片价格低于日、美（CREE）
8、晶片大小晶片的大小以边长表示，大晶片LED的品质比小晶片的要好。价格同晶片大小成正比。
9、胶体普通的LED的胶体一般为环氧树脂，加有抗紫外线及防火剂的LED价格较贵，高品质的户外LED灯饰应抗紫外线及 防火。
每一种产品都会有不同的设计，不同的设计适用于不同的用途，LED灯饰的可靠性设计方面包含：电气安全、防火安全、适用
环境安全、机械安全、健康安全、安全使用时间等因素。从电气安全角度看，应符合相关的国际、国家标准。
