Abstract
The utility model relates to an LED floodlight. The floodlight comprises a lamp housing body, a light source mounting plate and heat radiation vanes, wherein a drive power supply cavity and a light source cavity are respectively formed on the upper and the lower sides of the lamp housing body, the light source mounting plate is arranged in the horizontal direction inside the lamp housing body, a plurality of high-power LEDs are uniformly mounted on the light source mounting plate and are connected with the electrified lines of the light source mounting plate, heat radiation vanes are arranged outside the lamp housing body, and a double-cavity isolated layer is arranged between the drive power supply cavity and the light source cavity. The floodlight has the benefits that compared with the common floodlights, the floodlight has the characteristics of good radiating effect, long service life, and free maintenance in service cycle; and the special design of the cavity distribution structure sheaf and the radiating structure favors the stability of the lamp body structure, keeps favorable operating mode, and improves heat dissipation performance.
Description
Technical field
The utility model relates to a kind of floodlight, relates in particular to a kind of LED floodlight.
Background technology
General incandescent lamp, fluorescent lamp, electricity-saving lamp and other gas-discharge lamp all have filament or electrode, and the splash effect of filament or electrode is the restriction lamp inevitable assembly in service life.Hf electrodeless discharge lamp has high reliability. and service life is longer; Thereby the extra long life of floodlight has significantly reduced the worried and replacing number of times of maintenance, has saved material cost and labour cost, and can guarantee long-term normal the use; Because floodlight do not have electrode, be to combine with the fluorescence discharge principle and luminous, so there is not the inevitable assembly that limits the life-span by electromagnetic induction principle; Floodlight be meant a kind of can be to the spot light of all directions uniform irradiation, its range of exposures can be adjusted arbitrarily, floodlight can be placed in the scene Anywhere.For example, can be placed on beyond the video camera scope or interior of articles; The radiation response of floodlight is more stable, and this kind light has many secondary purpose, for example floodlight is placed on the position near body surface, then can produce bright light on body surface.But above all kinds of floodlight ubiquity certain defective, and cavity body structure is reasonable inadequately, and heat dispersion is relatively poor; In addition, the product of producing if drop into lower cost also can't reach better heat radiating effect.
The utility model content
At above defective, the utility model provides that a kind of long service life, cost are lower, the LED floodlight of perfect heat-dissipating, by the branch cavity configuration setting of innovation, thereby reaches the lighting effect that improves light fixture and reaches better heat radiating effect.
For achieving the above object, the utility model is by the following technical solutions:
A kind of LED floodlight, comprise lamp housing, light source installing plate and heat-dissipating fin, the both sides up and down of described lamp housing are provided with driving power chamber and light-source chamber respectively, the inboard horizontal direction of lamp housing is provided with the light source installing plate, some large-power light-emitting diodes evenly are installed on this light source installing plate and are connected with light source installing plate energising circuit; The described lamp housing outside is provided with heat-dissipating fin, is provided with the two-chamber separation layer between described driving power chamber and the light-source chamber.
The beneficial effect of LED floodlight described in the utility model is: compare with general floodlight, have non-maintaining characteristics in good heat dissipation effect, long service life, the life cycle; By the branch cavity configuration layer and the radiator structure of particular design, help stability, maintenance good working order, the raising heat dispersion of lamp body structure.
Description of drawings
With reference to the accompanying drawings the utility model is described in further detail below.
Fig. 1 is the structural representation of the described LED floodlight of the utility model embodiment.
Among the figure:
1, lamp housing; 2, light source installing plate; 3, large-power light-emitting diodes; 4, fixation kit; 5, bolt; 6, driving power chamber; 7, light-source chamber; 8, heat-dissipating fin; 9, two-chamber separation layer.
The specific embodiment
As shown in Figure 1, the described LED floodlight of the utility model embodiment, comprise lamp housing 1, light source installing plate 2 and heat-dissipating fin 8, the both sides up and down of described lamp housing 1 are provided with driving power chamber 6 and light-source chamber 7 respectively, lamp housing 1 inboard horizontal direction is provided with light source installing plate 2, some large-power light-emitting diodes 3 evenly are installed on this light source installing plate 2 and are connected with light source installing plate 2 energising circuits; The lamp holder afterbody is the fixation kit 4 of delivery guidewire, and described lamp housing 1 both sides screw fastening by bolt 5; Described lamp housing 1 outside is provided with heat-dissipating fin 8, be provided with two-chamber separation layer 9 between described driving power chamber 6 and the light-source chamber 7, by the branch cavity configuration layer and the radiator structure of particular design, help stability, maintenance good working order, the raising heat dispersion of lamp body structure.
Above embodiment is the more preferably specific embodiment a kind of of the utility model, and the common variation that those skilled in the art carry out in the technical program scope and replacing should be included in the protection domain of the present utility model.
