The LED illumination lamp comprises an aluminum bottom plate and the upper surface of the bottom plate is provided with a plurality of LED luminous sources. The LED illumination lamp is characterized in that a heat radiator provided with a plurality of heat radiation sheets is arranged on the lower surface of the bottom plate and a fan is further arranged below the heat radiator; the LED illumination lamp further comprises a penetrating bottom plate and heat radiation holes of the heat radiator; a transparent lamp cover is fixedly connected with the upper surface of the bottom plate; and air vents are arranged on the periphery of the lower part of the lamp cover. The LED illumination lamp has good heat radiation effect, solves the problem of PN bond temperature rise of an LED chip, improves the working efficiency of the LED lamp and reduces the light attenuation caused by the temperature rise.

Description

The LED lighting

Technical field

The utility model belongs to the LED field of light fittings, particularly a kind of LED lighting of good heat dissipation effect.

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 utility model provides a kind of good heat dissipation effect, can effectively solve the problem of led chip PN junction temperature rise, improves the operating efficiency of LED light fixture, reduces because the light decay that temperature rise causes.

The utility model is realized through following technical scheme:

The LED lighting; It comprises the base plate of aluminum, and the upper surface of described base plate is provided with a plurality of LED light emitting sources, it is characterized in that: the lower surface setting of said base plate has the radiator of a plurality of fin; The below of radiator also is provided with fan; Also comprise the louvre that penetrates base plate and radiator, also be fixedly connected with Transparent lamp shade, around the bottom of lampshade, be provided with air-vent at the upper surface of base plate.

Comprise that also a protection lampshade covers on the Transparent lamp shade, and the connecting plate between protection lampshade and the Transparent lamp shade is provided with through hole.

The utility model carries out one through the fan that is provided with to the LED light emitting source forces cooling; And in air-flow circulation of the inner formation of LED lighting; Can effectively and fast heat be distributed; The temperature rise of control LED light emitting source reduces whole light fixture owing to the light decay that temperature raises and causes, and has improved the light efficiency of LED lighting.

Description of drawings

Fig. 1 is the structural representation of the utility model;

Among the figure, 1 is louvre, and 2 are the protection lampshade, and 3 is Transparent lamp shade, and 4 is the LED light emitting source, and 5 is air-vent, and 6 is base plate, and 7 is through hole, and 8 is radiator, and 9 is fan.

The specific embodiment

Below in conjunction with accompanying drawing and specific embodiment the utility model is further specified.

Referring to Fig. 1, the LED lighting, it comprises the base plate 6 of aluminum; The upper surface of described base plate 6 is provided with a plurality of LED light emitting sources 4, and the lower surface setting of said base plate 6 has the radiator 8 of a plurality of fin, and the area of dissipation that a plurality of fin are used to increase radiator is set; Improve radiating effect, the below of radiator 8 also is provided with fan 9, and fan 9 can increase the flowing velocity of the air of spreader surface; Improve the radiating effect of fin; Also comprise the louvre 1 that penetrates base plate 6 and radiator 8, the louvre of setting can be in the inner circulation that forms an air of LED lighting, and the heat of LED light emitting source is directly taken away in the control of being convenient to flow; Upper surface at base plate 6 also is fixedly connected with Transparent lamp shade 3, around the bottom of Transparent lamp shade 3, is provided with air-vent 5.

Comprise that also a protection lampshade 2 covers on the Transparent lamp shade 3, and protect the connecting plate between lampshade 2 and the Transparent lamp shade 3 to be provided with through hole 7, the protection lampshade of setting prevents that dust in air from entering into Transparent lamp shade inside.
