Abstract
The utility model discloses a large-power light-emitting diode (LED) lamp, which comprises at least one LED (1), a baseboard (2) for installing the LED, a lamp casing (3) and an installation lamp holder (4) and is characterized in that a radiating device (5) is arranged at the lower end of the baseboard (2). The radiating device (5) comprises radiating sheets (51) which are fixedly connected with the baseboard (2) through a first support (52). The radiating device (5) further comprises at least one radiating fan (53). The large-power LED lamp has the advantages that the radiating sheets (51) are contacted with the air for radiating, and the radiating fan (53) improves air circulation on the periphery of the radiating sheets (51). Through the double-radiating mode, radiating effect can be well achieved, and small volume, light weight and good radiating of the LED lamp can be ensured. Further, installation and replacement of components are convenient, replacement or abandonment is not required simultaneously, and the LED lamp is more energy-saving and environment-protection.
Description
Technical field
The utility model relates to illuminating lamp, specifically is a kind of high-powered LED lamp.
Background technology
The LED lamp is meant and adopts LED (Light-emitting Diode; Light emitting diode) technology is as the light fixture of main light emitting source; Little, the light weight of bulb volume of LED lamp; Again because of it gets final product driven for emitting lights through minimum electric current,, power saving energy-conservation than conventional lamp, and substitute conventional lights at lighting field gradually.Especially under demands such as the illumination of building outward appearance, city illumination, stage floodlighting, the high-powered LED lamp that single bulb power is higher is wide because of its operating environment, and light beam is concentrated, and has brought into play important role.
High-powered LED lamp comprises at least one light emitting diode, is used to install the substrate of light emitting diode, lamp outer casing and installation lamp holder; Lamp holder is installed to be arranged on the lamp outer casing; Through after lamp holder is installed is connected energising with power source base, light emitting diode work, generation electric heating flows; But the used heat that produces during the work of general high-powered LED lamp can't effectively shed, and causes luminous efficiency seriously to descend.Being defined as of LED service life, when the LED luminous efficiency be lower than former luminous efficiency 70% the time, can be considered the LED life termination.The LED luminous efficiency can reduce along with service time and number of times, and too high temperature then can be quickened the decay of LED luminous efficiency.
For improving this problem of heat radiation, the high-powered LED lamp that metal fin is set below substrate is also arranged, fin and air contact area are big more, and radiating effect is good more.But in actual use, fin is done greatly, causes the light fixture overall volume excessive, and quality is overweight; Fin is done for a short time, because substrate and metal fin all are arranged on lamp outer casing inside, atmosphere draught-free, radiating effect fail well to improve.And the metal fin of this type high-powered LED lamp and substrate be to adopt directly welding, and processing technology is complicated, occurs that substrate damage needs to change, or during the situation of scrapping, metal fin is changed simultaneously, scrapped together with substrate, neither practices thrift not environmental protection again.
The utility model content
The technical problem that the utility model will solve is, the deficiency to above-mentioned prior art exists provides a kind of good heat dissipation effect, and volume is little, light weight, and high-powered LED lamp is easily installed, changed to parts.
The technical solution of the utility model is: a kind of high-powered LED lamp; Comprise at least one light emitting diode, be used to install substrate, lamp outer casing and the installation lamp holder of light emitting diode; Its technical characterstic is, described substrate lower end is provided with heat abstractor, and described heat abstractor comprises fin; Described fin is fixedly connected with substrate through first support, and described heat abstractor also comprises at least one radiator fan.
After adopting above structure, compared with prior art, the utlity model has following advantage: fin contacts heat radiation with air; Radiator fan has then strengthened the circulation of fin ambient air, and the mode of this dual heat radiation makes high-powered LED lamp not need to increase simply under the prerequisite of fin; Better reach radiating effect, guaranteed that volume own is little, light weight; Good heat dissipation, and fin is connected with substrate through first support; Make that installation, the replacing of parts are convenient, do not need to change simultaneously or scrap, more saving, environmental protection.
As preferably, described fin is a sheet metal, and evenly distributes and be cylindric.This setting makes that the heat transmission of fin and air is convenient, good heat dissipation effect.
As improvement, described radiator fan is fixedly connected on the fin lower end through second support.This setting makes that radiator fan also can independent dismounting, is convenient to installation, maintenance and replacing.
As improvement, described lamp outer casing is provided with a plurality of air vents.This setting makes the air of light fixture inside and outside better to circulate, and makes radiating effect better.
As improvement, also be provided with reflection shield on the described substrate, described reflection shield is provided with the centre bore of the light ejaculation that supplies light emitting diode light.This setting makes that the utilization rate of the light that light fixture sends is higher.
As preferably, described reflection shield and lamp outer casing are fixed on the substrate both sides through screw.This setting makes that the syndeton between the lamp part is simply firm.
As improvement, described high-powered LED lamp also comprises the printing opacity light cover, and this setting plays a protective role to light emitting diode, and being difficult for being soaked with rain causes short circuit, when running into bump, also plays cushioning effect.

The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation.
Shown in Fig. 1 to 4; A kind of high-powered LED lamp comprises at least one light emitting diode 1, is used to install substrate 2, the lamp outer casing 3 of light emitting diode 1 and lamp holder 4 is installed that its technical characterstic is; Described substrate 2 lower ends are provided with heat abstractor 5; Described heat abstractor 5 comprises fin 51, and described fin 51 is fixedly connected with substrate 2 through first support 52, and described heat abstractor 5 also comprises at least one radiator fan 53; The used heat of generation dispels the heat through the fin 51 and the heat transmission of surrounding air during high-powered LED lamp work, and flows through radiator fan 53 acceleration air.
In this example, described fin 51 is a sheet metal, and evenly distribution is cylindric; Described radiator fan 53 is fixedly connected on fin 51 lower ends through second support 54; Described lamp outer casing 3 is provided with a plurality of air vents; Also be provided with reflection shield 6 on the described substrate 2, described reflection shield 6 is provided with the centre bore of the light ejaculation that supplies light emitting diode light 1; Described reflection shield 6 is fixed on substrate 2 both sides with lamp outer casing 3 through screw; Described high-powered LED lamp also comprises printing opacity light cover 7.
