LED energy-saving lamps and ordinary incandescent lamps, how to choose LED energy-saving lamps basic overview: LED is a semiconductor light-emitting diode, LED energy-saving lamps are high-brightness white LED light source, high light efficiency, low power consumption, long life, easy Control, maintenance-free, safe and environmentally friendly; is a new generation of solid cold light source, soft color, bright, colorful, low loss, low energy consumption, green and environmental protection, suitable for families, shopping malls, banks, hospitals, hotels, restaurants, his various public places Long time lighting.
characteristic:
1. Efficient and energy-saving: only a few kWh in a thousand hours (normal 60W incandescent lamp consumes 1 kWh for 17 hours, ordinary 10W energy-saving lamp consumes 1 kWh for 100 hours)
2, long life: semiconductor chip light, no filament, no glass bubble, not afraid of vibration, not easy to break, the service life can reach 50,000 hours (the average incandescent lamp life is only one thousand hours, the average energy-saving lamp life is only eight Thousand hours)
3, health: light health light does not contain ultraviolet and infrared rays, no radiation (normal light lines contain ultraviolet and infrared)
4. Green and environmental protection: It does not contain harmful elements such as mercury and antimony, which is good for recycling and does not cause electromagnetic interference. (Ordinary lamps contain elements such as mercury and lead, and electronic ballasts in energy-saving lamps can cause electromagnetic interference)
5, protection of vision: DC drive, no stroboscopic (normal lights are AC drive, it will inevitably produce strobe)
6, high light efficiency: low heat, 90% of electrical energy is converted into visible light (80% of ordinary incandescent energy is converted into heat, only 20% of electrical energy is converted into light energy)
7. High safety factor: less voltage and current required, less heat, no safety hazards, dangerous places such as mines
8. Market potential: low voltage, DC power supply, battery, solar power supply, lack of electricity, less electricity in remote mountain areas and outdoor lighting.
Comparison of led energy-saving lamps and ordinary incandescent lamps:
1. The led energy-saving lamp has the same stroboscopic phenomenon as the ordinary incandescent lamp under the AC drive, while the ordinary energy-saving lamp has no stroboscopic phenomenon. Strobe makes the eyes easy to fatigue.
2, the light of each LED bulb is too bright, it will strongly irritate the eyes, can not be directly looked at, even for a short time, and the ordinary energy-saving lamps are relatively softer!
3, the illumination angle is limited, generally only 120 °, and ordinary energy-saving lamps can be irradiated 360 °.
4. The brightness of the illuminated room is not better than the energy-saving lamp, because the LED has high brightness only in the narrow angle of direct view, and the light is rapidly weakened after deviating from the angle.
Therefore, the advantages of LED energy-saving lamps as indoor lighting fixtures are not necessarily better than ordinary energy-saving lamps, but they are still excellent when used as flashlights, desk lamps, spotlights, etc., which only need to illuminate narrow angles.
How to choose LED energy saving lamps:
1, LED brightness (MCD) is different, the price is different. LEDs for LED luminaires shall comply with the laser class I standard.
2, anti-static ability Anti-static ability of the LED, long life, and therefore high price. Generally, LEDs with an antistatic greater than 700V can be used.
LED lighting .
3. LEDs with the same wavelength have the same color. If the color is consistent, the price is high. It is difficult for manufacturers without LED spectrophotometers to produce pure color products.
4. Leakage current LED is a unidirectional conductive illuminator. If there is reverse current, it is called leakage, and LED with large leakage current has short life and low price.
5. LEDs with different illumination angles have different illumination angles. Special lighting angle, the price is higher. Such as the full diffusing angle, the price is higher.
6. The key to different quality of life is life, and life is determined by light decay. Low light decay, long life, long life and high price.
7. The illuminator of the wafer LED is a wafer, and the price of the wafer varies greatly. The chips in Japan and the United States are more expensive, and the prices of wafers in Taiwan and China are generally lower than those in Japan and the United States ( CREE ).
8. Wafer Size The size of the wafer is indicated by the side length. The quality of the large wafer LED is better than that of the small wafer. The price is proportional to the size of the wafer.
9, colloidal ordinary LED colloid is generally epoxy resin, LED with anti-ultraviolet and fire retardant is more expensive, high-quality outdoor LED lighting should be resistant to UV and fire. Each product will have different designs. Different designs are suitable for different purposes. The reliability design of LED lighting includes: electrical safety, fire safety, environmental safety, mechanical safety, health and safety, and safe use time. From the perspective of electrical safety, it should comply with relevant international and national standards.
