LED tungsten filament lamp

Technical Field

The utility model relates to an illumination lamps and lanterns field especially involves a LED tungsten filament lamp.

Background

Tungsten filament lamps are incandescent lamps made of tungsten filaments as filaments. The tungsten filament lamp can generate continuous spectrum and is used in the visible spectrum region of 400-780 nm. As a visible light source in a spectrophotometer. Its spectral effective region can be extended to 3 μm, and thus it is also used as a light source in the near infrared region. Since the latter half of the nineteenth century, tungsten filament incandescent lamps, which are one type of lighting device, have been used, leading to the introduction of electrical light sources into homes. With more than a hundred years of use, people have become accustomed to the shape, brightness, and color of incandescent lamps. Tungsten filament incandescent lamps have been used not only as a lighting device, but have also entrusted people with family, familiarity, companions, nostalgia, and the like. In modern society, with the continuous development of material civilization, various lamps begin to move to people's lives, and emerging lamps become more and more the targets of our exploration, and the LED tungsten lamp is just emerging product.

For example, the Chinese patent publication No. CN203771092U discloses an LED imitation tungsten filament bulb, which comprises a lamp holder, a glass bulb, a sensing column, a lead and an LED light-emitting unit, wherein the appearance shape is similar to that of a traditional tungsten filament incandescent lamp, the color temperature is close to that of the traditional tungsten filament incandescent lamp, the LED imitation tungsten filament bulb is used for replacing the traditional tungsten filament incandescent lamp, the psychological conflict emotion of people can be effectively reduced, the popularization and the application of the novel LED lighting equipment are facilitated, compared with the tungsten filament bulb, the energy is saved by 90%, compared with the common LED lamp, the energy is saved by 30%, and the purposes of energy saving and environmental protection are achieved. However, the patent has poor illumination effect.
