LED desk lamp is a desk lamp with LED (light emitting diode) as light source. LED is a solid-state semiconductor device, which can directly convert electricity into light. The LED lighting technology is the third generation lighting technology.
LED lighting, also known as solid-state lighting, as the third generation of lighting technology after incandescent lamp and fluorescent lamp, has the characteristics of energy saving, environmental protection, safety and reliability. Solid state light source is a promising new light source to replace traditional lighting appliances in the next decade, representing the future of lighting technology. The development of new solid-state lighting is not only a revolution in the field of lighting, but also in line with the requirements of "building a resource-saving and environment-friendly society" proposed by the current government.
LED desk lamp has many advantages
1. High efficiency
The luminous efficiency of high-power LED has exceeded 100 LM / W, and the luminous efficiency of LED is far higher than that of incandescent lamp because the spectrum of LED is almost concentrated in the visible light band, and it is catching up with energy-saving lamp and fluorescent lamp.
2. High light quality
Because there is no ultraviolet and infrared in the spectrum, there is no heat, no radiation, it will not bring burden to the eyes, and there will be no pain and swelling in the eyes when reading or working for a long time.
3. Good color rendering
Compared with fluorescent lamp, the color rendering index of high-power LED desk lamp is high, usually about 80. This is conducive to reducing the fatigue degree of human eyes and is of great help to the protection of eyesight.
4. Low maintenance cost
LED has long life, luminous flux half-life is more than 50000 hours, and it is generally used for more than 30 years. There are no easily damaged parts such as tungsten wire and glass shell, so the possibility of abnormal "scrapping" is very small.
5. Small size
It can make the lamp small and delicate, more suitable for different places of use.
6. It can be used as emergency lighting
With the battery, it is easy to turn the desk lamp into an emergency lamp. Help people evacuate and light up in case of power failure or emergency.
7. Green environmental protection
The waste is recyclable and pollution-free, unlike fluorescent lamps, which contain mercury.
8. Safe driver
There are many ways to drive LED, in the table lamp products we use low voltage constant current drive. The constant current driving mode is an ideal LED driving mode, which can avoid the current variation caused by the change of led forward voltage, and the constant current makes the brightness of LED stable.
Generally, the light source driven by alternating current has the stroboscopic effect, which will make the visual nerve easily tired by the constantly changing light intensity stimulation. The LED driven by constant current can emit stable light without stroboscopic phenomenon, which makes the vision feel very comfortable.
The table lamp is a safe low voltage input, which avoids the safety accident caused by the circuit failure of ordinary lamps.
9. Efficient optical system
An excellent lamp should have an efficient optical system, and the efficient light reflector is one of the most technical components. It has high reflectivity, good light control angle and uniformity of reflected light.
We use computer simulation to design the optical system of the lamp, so that the light from the LED is redistributed through the reflector, lens and other optical devices, and the light distribution is reasonable, which fully meets the design requirements. After anodizing treatment, the reflector has high reflection efficiency and good durability. The lampshade made of light mixing material with high transmittance can maintain the high efficiency of the optical system and reduce the glare.
We should pay special attention to the glare of lamps and lanterns when we buy desk lamps as study and work lighting appliances at ordinary times, and do not let the light cast on the eyes in a straight line. Because the light is directly projected on the eyes, the eyes will have photophobia and easy to get tired, and the pupil will shrink and feel dark around, resulting in blurred vision. Long time in this glare lighting environment reading, writing, vision will be greatly damaged. Eye hygiene, first of all, should start with high-quality lighting, which requires us to pay more attention to the luminous quality when we buy table lamps.
10. Heat dissipation of desk lamp
Heat dissipation is the main factor affecting the use of table lamp LED, and the heat dissipation of devices and lamps is very important in the application process of high-power LED. We fully design the LED packaging and secondary heat dissipation, using hollow metal radiator with fins and metal lampshade to reduce the thermal resistance of LED light source and obtain good overall thermal characteristics
11. Modeling design of overall structure
Excellent lamps not only have high-quality LED, high-quality electrical components, high-efficiency reflector, reasonable structure, but also have good product modeling design.
In the design of high-power LED desk lamp, we make full use of the characteristics and advantages of high-power LED. On the premise of meeting the practical needs and maximizing the efficiency of light source, we carry out the miniaturization design of lamps and lanterns. The overall design of lamps and lanterns is small and exquisite, which can be suitable for different places of use. So that the appearance of the lamps and lanterns has beautiful, comfortable, durable and other aesthetic effects, and can coordinate with the environment.
The structural parts of lamps and lanterns can be made of metal materials, which give people the characteristics of durability and high-grade, reflecting the characteristics of high-grade and modern products, and are widely used in office and learning places.
