Abstract
The invention belongs to the field of light-emitting diode (LED) lamps, particularly relates to an LED lamp which is good in radiating effect and capable of effectively controlling temperature rising of LED luminous sources, and comprises a base plate provided with a lamp shade having a sealing protection function. The LED lamp is characterized in that an installation plate provided with an arched section and located in the lamp shade is arranged on the base plate, a plurality of LED luminous sources are arranged on the outer surface of the installation plate, and a plurality of radiating fins are arranged on the inner surface of the installation plate. By means of improvement on the structure of an LED fixing plate and an additionally arranged forced cooling device, a radiating effect is improved so that the temperature rising of the LED luminous sources is effectively controlled, and the problem of the temperature rising of the LED luminous sources is effectively solved.
Description
Technical field
The invention belongs to the LED field of light fittings, particularly a kind of good heat dissipation effect can effectively be controlled the LED light fixture of LED light emitting source temperature rise.
Background technology
Development and maturation along with the LED technology; The performance indications of LED increase substantially day by day, and at present, the light efficiency of white light LEDs has has met or exceeded the light efficiency level of ordinary incandescent lamp; Luminous flux is also increasing significantly, makes LED obtain using widely at lighting field.LED compares with the energy-saving lighting lamp that general photo-voltaic power supply is used, have the life-span long, heating is low, not fragile, power consumption is little and more energy-conservation outstanding advantage, people it be described as 21 century replace fluorescent lamps and incandescent lamp the 4th generation lighting source.
The core luminous component of led chip is the PN junction that has P type and N-type semiconductor to constitute, and when the forward current PN junction of flowing through, the heat generation loss makes the interface produce temperature rise; Gather heat, as effectively not dispelling the heat, the too high meeting of temperature causes led chip generation light decay effect; The luminous intensity that is LED reduces, near room temperature, and 1 ℃ of the every rising of temperature; The luminous intensity of led chip also can correspondingly reduce about 1%, and must taking effectively, heat radiation solves the light decay problem.
Summary of the invention
To above-mentioned technical problem, the present invention provides a kind of and increases forced cooling device through the structure of LED fixed head is improved, and has improved radiating effect, thereby has effectively controlled the temperature rise of LED light emitting source, has effectively solved the problem of LED light emitting source temperature rise.
The present invention realizes through following technical scheme:
The LED light fixture; It comprises base plate; Base plate has been provided with the lampshade of seal protection effect; It is characterized in that: described base plate is provided with a cross section and is arch and is positioned at the inner installing plate of lampshade, and the outer surface of described installing plate is provided with a plurality of LED light emitting sources, and the inner surface of installing plate is provided with a plurality of fin.
Described installing plate is semielliptical shape.
Described installing plate is hemispherical.
Described base plate is provided with fresh air inlet and exhaust vent, and the base plate that described fresh air inlet goes out is provided with a fan.
In sum, the present invention improves through the structure to the installing plate of LED light emitting source, and at the inner surface of installing plate fin is set; Increased area of dissipation, improved radiating effect, simultaneously fan through setting up; Improve the flowing velocity of installing plate ambient air; Improve radiating rate with this, effectively controlled the problem of temperature rise of LED light emitting source by the way, improved the light efficiency of LED light fixture.

The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is further specified.
Referring to Fig. 1; The LED light fixture; It comprises base plate 7, and base plate 7 has been provided with the lampshade 2 of seal protection effect, and described base plate 7 is provided with a cross section and is arch and is positioned at the inner installing plate 3 of lampshade; The outer surface of described installing plate 3 is provided with a plurality of LED light emitting sources 4, and the inner surface of installing plate 3 is provided with a plurality of fin 5.
Described installing plate 3 is semielliptical shape or hemispherical, and installing plate is semielliptical shape or hemispherical, can increase the quantity that the LED light emitting source is set, and has enlarged the illumination zone of LED light fixture.
Described base plate 7 is provided with fresh air inlet 6 and exhaust vent 1; The base plate 7 at described fresh air inlet 6 places is provided with a fan 8; The fan 8 that is provided with can be blown into the cavity that installing plate forms with air, and comes out through venthole, in the internal face formation circulation of air of installing plate; Improve the flowing velocity of installing plate internal face air, improved radiating efficiency.
In sum, the present invention improves through the structure to the installing plate of LED light emitting source, and at the inner surface of installing plate fin is set; Increased area of dissipation, improved radiating effect, simultaneously fan through setting up; Improve the flowing velocity of installing plate ambient air; Improve radiating rate with this, effectively controlled the problem of temperature rise of LED light emitting source by the way, improved the light efficiency of LED light fixture.
