Advantages and disadvantages led bulbs and energy-saving lamps

a. Advantages of energy-saving lamps:

incandescent light bulbs, energy-saving light energy conversion rate is much higher, save electricity, also can reduce the emissions of greenhouse gases, long service life.

2. Energy-saving lamps drawback:

1. Energy-saving lamps start slowly.

2。 Energy-saving lamp is open line spectrum, so usually purple light of energy-saving lamps, see things will badly discolored under the energy-saving lamps. Looks blue will be purple, red and yellow is more bright. So you should not use energy-saving lamps in the color of the workplace.

3。 Scientists through investigation and study for a long time to get a preliminary conclusion: energy-saving lamp radiation may pose a risk to human health, and even cause cancer.

the advantages and disadvantages of LED lights

a, the advantages of LED lights

1. High energy saving, energy saving energy is the environmental protection from pollution. Dc drive, ultra-low power electric power conversion is close to 100%, the same lighting effect than the traditional light source, energy saving more than 80%.

2。 Long life: LED light source has called it longevity light, meaning never extinguished the lights. Solid cold light source, the epoxy resin encapsulation, no loose parts in the body, there is no filament light easy to burn and thermal deposition, droop, such as faults, service life can reach 60000 to 100000 hours, long service life 10 times more than traditional light.

3。 Many changes: LED light source available red, green, blue three colors principle, in under the control of computer technology make the three colors gray level 256 and arbitrary mixed, can produce 256 & times; 256× 256 = 16777216 kinds of color, form different combinations of light color changing, realize the dynamic change of rich and colorful effects and all kinds of images.

4。 The environmental protection, environmental protection benefit is better, no ultraviolet and infrared spectrum, no heat, no radiation, glare small, and waste recoverable, no pollution contains no mercury elements, cold light source, can safely touch, belongs to typical green lighting source.

5。 High tip: compared with the traditional monotonous lighting effects, the LED light source is low pressure microelectronics products, successfully combines computer technology, network communication technology, image processing technology, embedded control technology, etc. , so also is the digital information technology products, is a semiconductor photoelectric device & other; High point & throughout; Technology, with online programming, unlimited upgrades, flexible characteristic.

leds faults:

1. LED lights can not completely replace incandescent lamp; Luminous flux, luminous efficacy and color rendering, but now it's too expensive and will not decline in recent years. But the luminous flux can improve the product so as to reduce the cost of replacing incandescent lamp.

2。 Leds shall simply use light source; It used to drive power supply, optical and thermal conduction.

3。 Leds also fever, need to heat dissipation.
