Abstract

The invention belongs to the field of LED (light emitting diode) lamps, and particularly relates to a long strip LED lamp with good heat dissipation effect. The long strip LED lamp comprises a baseplate used for installing multiple LED light emitting sources and a lamp shell used for protect an LED; and the LED lamp is characterized in that the upper surface of the baseplate is provided with a finned radiator, a cooling fin of the finned radiator is arranged along a long side direction of the baseplate, and the LED lamp also comprises a cover shell used for protecting the finned radiator. The LED lamp provided by the invention has the advantages that the heat dissipation effect is good, the problem of LED chip PN (performance number) junction temperature is effectively solved, the work efficiency of the LED lamp is improved, and lumens depreciation caused by temperature rise is reduced.

Description

Strip LED light fixture

Technical field

The invention belongs to the LED field of light fittings, particularly a kind of strip LED light fixture 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 present invention 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 present invention realizes through following technical scheme:

Strip LED light fixture; It comprises a base plate that a plurality of LED light emitting sources are installed; And the lamp housing that LED is protected; It is characterized in that: the upper surface of described base plate is provided with gilled radiator, and the fin of described gilled radiator also comprises the case that gilled radiator is protected along the long side direction setting of base plate.

The exhaust vent that the left end of described case is provided with, the right-hand member of case is provided with fresh air inlet, and also is provided with the fan of aiming at fresh air inlet at the right-hand member of case.

In sum, the present invention improves radiating effect through gilled radiator is improved and set up to the structure of strip LED light fixture, can effectively control the temperature rise of LED light emitting source, improves the light efficiency of LED light emitting source, improves the illumination capability of strip LED light fixture.

Description of drawings

Fig. 1 is a structural representation of the present invention;

Fig. 2 be Fig. 1 A-A to cutaway view;

Among the figure, 1 is lamp housing, and 2 is exhaust vent, and 3 is case, and 4 is gilled radiator, and 41 is fin, and 5 is base plate, and 6 is fresh air inlet, and 7 is fan, and 8 is the LED light emitting source.

The specific embodiment

Below in conjunction with accompanying drawing and specific embodiment the present invention is further specified.

Strip LED light fixture as depicted in figs. 1 and 2; It comprises a base plate 5 that a plurality of LED light emitting sources are installed, and the lamp housing 1 that LED is protected, and the upper surface of described base plate 5 is provided with gilled radiator 4; The fin 41 of described gilled radiator 4 is along the long side direction setting of base plate; Also comprise the case 3 that gilled radiator 4 is protected, case 3 can reduce the accumulation of dust on gilled radiator, helps guaranteeing the radiating effect of gilled radiator.

The exhaust vent 2 that the left end of described case 3 is provided with; The right-hand member of case 3 is provided with fresh air inlet 6, and also is provided with the fan of aiming at fresh air inlet 67 at the right-hand member of case 3, when the fan 7 of setting is worked; Can improve the speed air flow on gilled radiator surface, improve radiating efficiency.
