Description
Technical field
The utility model relates to a kind of lighting, especially uses semiconductor light-emitting-diode LED UFO-shape bulb as the light fixture of lighting source.
Background technology
Semiconductor technology has caused first Industrial Revolution---after the microelectronic revolution, just breeding a new revolution now---and the illumination revolution.Along with the appearance of third generation semi-conducting material gallium nitride, the semiconductor technology forward mankind devote another achievement: with solid-state illumination---the semiconductor lamp of semiconductor light-emitting-diode LED as new light sources, replace conventional incandescent and fluorescent lamp.Because semiconductor light-emitting-diode LED light fixture has the power consumptive province, its power consumption only has the characteristics of incandescent lamp 1/10, is fit to do energy-saving lighting lamp and uses.Because semiconductor light-emitting-diode LED is the dc low-voltage current drives, high-quality driving power provides the Constant Direct Current that is similar to dry cell can for semiconductor light-emitting-diode LED, thoroughly eliminates the stroboscopic of alternating current, makes the reading portable lamp light source of high-quality again.
The attraction of so-called fluorescent lamp " eye-protecting desk lamp " is to claim " without stroboscopic, having eye-protecting function " on the market.Great majority " eyeshield " desk lamp is the principle that adopts electric ballast that fluorescent lamp is worked under high frequency electric, and frequency is usually more than 20kHz.This frequency makes almost imperceptible high frequency flicker of naked eyes for the 50Hz that fluorescent lamp is worked under power current.Even if but naked eyes are imperceptible, stroboscopic still exists.
Electricity-saving lamp also is fluorescent lamp.The stroboscopic that energy-saving bulb produces is although naked eyes are imperceptible.But as long as usually can observe the striped that stroboscopic produces with the camera on the mobile phone or digital camera.Such light source has stroboscopic, and for a long time reading work under this lamp causes eye fatigue easily.
In view of these problems of " eye-protecting desk lamp " and fluorescent lamp bulb, people substitute these light sources with the LED bulb now.Common are in the lampshade that the LED globular bulb is installed in desk lamp and use.But such light source also has many defectives.The illuminator of LED globular bulb is with one or several great power LEDs mostly.Great power LED is luminous more concentrated, and the lighting under the lamp is bad.In addition, owing to the needs of mounting circuit in lamp and radiator, the height of these globular bulbs is all done greatlyr, and bulb reaches the outside of lampshade easily, and the light that bulb sends can directly be mapped to user's eyes, causes the dazzle of perverse eye.
Summary of the invention
The purpose of this utility model has provided a kind of desk lamp with LED UFO-shape bulb, and is energy-conservation, without stroboscopic and free from glare, is suitable for reading and work.
For realizing above purpose, the technical solution of the utility model is:
A kind of desk lamp with LED UFO-shape bulb comprises lampshade, switch, lamp socket, support and base, it is characterized in that:
Also comprise the LED UFO-shape bulb that is installed in the described lampshade, the rear end of this bulb is threaded with lamp socket with switch.
Described LED UFO-shape bulb comprises lamp housing, LED and screw socket, is provided with to the outside a plurality of LED in the lamp housing, and the front of lamp housing is translucent cover, and the rear end is connected with screw socket.
In described lamp housing, be provided with at least 10 low-power LEDs.
The orthographic projection of lamp housing front is circular, and its diameter A is greater than the vertical height B of screw socket top, rear end salient point to the lamp housing front, i.e. A〉B.
Salient point is to the vertical range H of lampshade bead from the lamp housing front〉1cm.
Described support is folding bracket.
Described base is disc gravity base or clamp type positioning base.
The desk lamp with LED UFO-shape bulb of above structure, the diameter of this bulb lamp housing frontal plane of projection is greater than the bulb height, make the profile of bulb be UFO-shape, greatly enlarge the light-emitting area of bulb, without stroboscopic, has eye-protecting function, change the in the past little profile of LED globular bulb light-emitting area, enlarge light-emitting area and then can adopt low-power LED, the interval is wide between the low-power LED, the low-power LED caloric value is few, can not use radiator, thereby has saved the space of radiator, realized dwindling the purpose of the height of bulb, and adopt a plurality of low-power LEDs in light-emitting area, can also the luminous face of changing into the UFO-shape bulb of the point of globular bulb is luminous, can obtain cloth light curve under the good lamp.
With this light-emitting area greatly, highly less UFO-shape bulb is installed in the wide-mouth lampshade of desk lamp, and make UFO-shape light bulb base and lampshade bottom maintain certain distance, can guarantee that the light that sends can directly not be mapped to user's eyes, avoid causing the dazzle of perverse eye.
The utility model adopts low-power LED, has energy savings, does not have the advantage such as fluorescent lamp mercury pollution, can also satisfy the reading portable lamp simultaneously to the cloth light curve, without the requirement of the aspects such as stroboscopic, free from glare.
