Abstract
The invention relates to an energy-saving lamp, in particular to an LED lamp with high lighting quality. The LED lamp comprises a lamp housing and a lamp core, and is characterized in that dispersed fluorescent powder and a blowing device are mounted in the lamp housing. Preferably, the blowing device consists of a micro-motor, a micro-fan and a blowing pipe. Further preferably, the blowing device comprises a mini air pump and a blowing pipeline. Since the fluorescent power is dispersed rather than fixed on the lamp housing, the fluorescent power is blown to be spread and fill the whole lamp housing by the blowing device before the lamp core is lighted, then light emitted from the lamp core is uniform in distribution, irradiates the whole space of the lamp housing without light spots uneven in brightness, and lighting quality is improved further. Since the LED lamp is provided with the blowing device, heat on an LED chip can be dissipated in time and can be transmitted to the surrounding of the lamp housing uniformly, and then heat dissipation of the LED lamp is improved greatly, and the service life of the LED lamp is prolonged obviously. In addition, lighting efficiency is increased by reducing temperature rise of the LED lamp.
Description
Technical field
The present invention relates to a kind of electricity-saving lamp, relate in particular to a kind of LED lamp that can improve lighting quality.
Background technology
Along with expanding economy, the progress of society, energy conservation has become inevitable and social consensus.The LED light fixture is as the green illumination of environmental protection and energy saving, in illuminating industry just flourish.The LED lamp is as novel lighting source, and it has the advantages such as energy-saving and environmental protection, long service life, low consumption, has been widely used in domestic lighting, commercial lighting, highway lighting, industrial and mineral illumination etc.
But, the following problem of the at present LED lamp of application existence: there is the inconsistent problem of the light uniformity in (1) LED lamp: the wick of LED lamp is comprised of according to certain shape many LED core bands, what have is triangular in shape, being of having is square, and LED core band is again to be in series by the little chip of a plurality of LED.When lightening LED lamp throws light on, in the scope of shining, there is the inhomogeneous shortcoming of light and shade, that is to say to exist according to and do not work that the situation of light and shade hot spot is arranged.
(2) there is the problem of heat radiation in the LED lamp: depend on its junction temperature the service life of LED lamp fully.As long as junction temperature is enough low, the Service life to ten of LED was no problem more than ten thousand hours.But because the luminous efficiency of LED itself is present still lower, 70% input power will be converted into heat energy approximately in addition, if these heat can not distribute well, the junction temperature of LED will raise, so the life-span of LED lamp will decrease.Improve exactly its heat radiation so prolong the basic way in LED life-span.
(3) there is the problem of lighting quality in the LED lamp: because the core luminous component of LED lamp is PN junction LED tube core, PN junction LED tube core can produce a large amount of heats in the process of photon excitation light-emitting phosphor, if heat can not in time be led away, the luminous efficiency of PN junction LED tube core and luminous mass will significantly descend along with the rising of temperature, fluorescent material also can be accelerated to wear out, and will have a strong impact on luminous mass, the lighting quality of LED lamp.
Summary of the invention
The object of the present invention is to provide a kind of luminous evenly, the LED lamp of good, the high lighting quality of heat radiation.
For achieving the above object, technical solution of the present invention is: a kind of LED lamp of high lighting quality, comprise lamp housing, wick, and it is characterized in that: discrete shape fluorescent material and blowing device are housed in the described lamp housing.
As this practical preferred version, described blowing device is comprised of micromachine, mini-fan and blowing pipeline.
As this practical another preferred version, described blowing device comprises micro air pump, blowing pipeline.
As this another practical preferred version, described lamp housing is double-deck lamp housing, described double-deck lamp housing is comprised of interior lamp housing and lamp housing, the fluorescent material of discrete shape is housed between double-deck lamp housing, described blowing device is installed in interior lamp housing the inside, described blowing device is comprised of micromachine, mini-fan and blowing pipeline, and described blowing pipeline stretches to the bottom of lamp housing by wick, interior lamp housing.
Further, described blowing pipeline is provided with a lot of air vents at the position by wick.
As this practical again preferred version, described lamp housing is double-deck lamp housing, described double-deck lamp housing is comprised of interior lamp housing and lamp housing, the fluorescent material of discrete shape is housed between double-deck lamp housing, described blowing device is installed on the lamp panel, described blowing device is comprised of micro air pump and blowing pipeline, and described blowing pipeline passes the bottom that interior lamp housing stretches to lamp housing.
Further, described blowing pipeline is claw type.
Operation principle of the present invention is as follows: when starting power switch, blowing device begins blowing, fluorescent material in the LED lamp housing blown out fill the air shape, be full of in the whole lamp housing, the led chip time-delay started in 0.5～1 second, the monochromatic light irradiation fluorescent material that sends, thus white, uniform light sent, shine uniformly whole field of illumination.
The invention has the beneficial effects as follows: (1) is because fluorescent material of the present invention is discrete shape, be not fixed on the lamp housing, before wick is luminous, just blown out by blowing device first and fill the air shape, be full of in the whole lamp housing, the luminous energy that wick is sent evenly distributes, the whole space of uniform irradiation can not produce the hot spot that light and shade differs, and has further improved the quality of illumination.
(2) the present invention can in time take away the heat on the led chip owing to adopted blowing device, and timely even transferring heat around the lamp housing has greatly improved the heat dissipating state of LED lamp, the service life of having improved significantly the LED lamp; The fluorescent material that is discrete shape in the LED lamp is equivalent to a kind of powder of flowability, and light was evenly distributed, and the heat transmission of led chip can be scattered again.
(3) amount of heat that in time led chip produced of the air-flow among the present invention evenly to around disperse, the temperature of PN junction tube core significantly reduces.Because luminous mass and its temperature of PN junction tube core have very large correlation, temperature rising luminous mass obviously descends, and temperature reduces luminous mass and significantly rises, so LED lamp luminous mass of the present invention is better, lighting quality is higher.
(4) the luminous efficiency following temperature rising of LED lamp and descending.When junction temperature is 25 ℃, luminous efficiency 100%; When junction temperature was 150 ℃, luminous efficiency only was 70%.The present invention has also improved luminous efficiency by reducing the LED temperature rise except the lighting quality that has improved the LED lamp, thereby the power that compensation micro machine or gentle breeze fan consume makes the efficient of whole system with originally substantially suitable, even slightly is improved.
