Natural light bulb and portable eye protecting desk lamp

Abstract

The invention discloses a natural light bulb and a portable eye protecting desk lamp using the natural light bulb. The natural light bulb comprises an interface, a lamp housing, an aluminum base plate, a diffused reflector, an interface disengagement-prevention connecting element and a power supply driving module, wherein one end of the interface disengagement-prevention connecting element is tightly screwed with the interface; the other end of the interface disengagement-prevention connecting element is connected with the lamp housing; and the power supply driving module is arranged in the center of the interface disengagement-prevention connecting element. LED lamp beads are arranged on the aluminum base plate in a high-redundancy board distribution mode, and are set to a state that theluminous efficacy is greater than 120 lumens per watt. The portable eye protecting desk lamp comprises a base, a lamp head, a support frame, a light source interface, the natural light bulb and a power supply, and also comprises a clamp used for fixing the base. A suction plate is arranged on the clamp to realize the fixation to the base in a magnetic suction mode. The natural light bulb and the portable eye protecting desk lamp have the advantages of high performance, high comfort, portability, easy maintenance and the like.

Description

technical field [0001] The invention relates to a natural light bulb and a portable eye-protecting desk lamp, belonging to the field of lighting engineering. Background technique [0002] At present, there are all kinds of lighting fixtures on the market, and eye protection or natural light have become keywords for many people to buy lighting fixtures. In fact, the selection factors most directly related to desk lamps are color rendering index, color temperature and luminous flux. [0003] The color rendering index is one of the most important characterization parameters of the light quality, which is the core index to measure the color reproduction of light in the lighting industry. The color rendering index of visible light from the sun is 100. The color rendering index is a comprehensive value, expressed in Ra, usually Ra above 90 is regarded as excellent light. As for lamps used in home or office, Ra should be at least higher than 80. The color rendering index of com...

AI Technical Summary

Problems solved by technology

In fact, it is difficult for lighting products in the domestic market to meet these requirements.

Incandescent lamps have high color rendering index, but low color temperature, stroboscopic, low luminous flux, and high operating temperature

The tri-color energy-saving light has large flux, uniform light output and optional color temperature, but it has stroboscopic, insufficient luminous flux, high working temperature and low color rendering

Halogen lamps have high color rendering and large luminous flux, but the power is too high, the working temperature is too high, there are many ultraviolet and infrared rays, and the service life is short

As for LED lamps, although the products of middle and high brands are often beautiful and adjustable, they generally have low color rendering and small luminous flux.
