Abstract
The utility model discloses an LED (light-emitting diode) yard lamp. The LED yard lamp comprises a lamp holder part and a lamp body part connected therewith, wherein the lamp holder part comprises a lamp holder housing, a lamp cap and a circuit board; the lamp body part comprises a lampshade, and a group of aluminum substrate lamp panels mounted in the lampshade and evenly distributed in a cylinder shape; LED light-emitting elements are arranged on the aluminum substrate lamp panels; the yard lamp further comprises a convection mechanism which comprises internal-tooth aluminum profile heat radiators arranged on the inner side surfaces of aluminum substrates and a convection device; and the convection device is mounted at the lamp holder part and corresponds to a central part position encircled by the heat radiators. As an active convection heat radiating mechanism is mounted on the yard lamp with the structure, active heat radiation is achieved, heat guided out by the heat radiators is taken away from the other sections of the profiles, heat radiation is quickened, the heat radiation efficiency is improved, and the light-emitting efficiency and the service life of the LED yard lamp are guaranteed; and furthermore, a PCB (printed circuit board) glass fiber plate is used to be connected with the aluminum substrate, and the original linear connection circuit is replaced by a circuit designed on the glass fiber plate, so that by adopting the connection manner, the LED yard lamp is simple to assemble, is stable and reliable, and saves time and space.
Description
Technical field
The utility model relates to lighting, specifically is a kind of LED garden lamp.
Background technology
The heat radiation major part of existing LED lighting all is passive heat radiation, and such lighting power is low, in case it is not enough to do the heat radiation of high-power LED lighting, just has the light decay phenomenon and occurs, and influences light efficiency and life-span.If area of dissipation is enough, the volume and weight of light fixture also has and can become very big so.
In addition, at present garden lamp 360 degree LED lightings on the market are that 8 directions are luminous, need 8 LED lamp plates, and being connected between the light fixture of this structure, lamp plate and the power supply is to connect with line.This kind mode is connected with following drawback: the one, and it is many to connect the end of a thread; The 2nd, assemble time-consuming; The 3rd, be assembled in a lot of lines in light fixture the inside and take up space and just look at up in a jumble, cause short circuit between line and the line easily; The 4th, line connects can not combine the aluminium base of led light source securely with heat radiation, because cause the distortion when transporting easily, finally cause light fixture bad.
The utility model content
At the problems referred to above, the utility model aims to provide a kind of LED garden lamp of active heat radiation; Another object of the present invention is to solve connecting circuit complicated and unstable, unsafe problem.
For realizing this technical purpose, scheme of the present utility model is: a kind of LED garden lamp, comprise lamp holder and connected lamp body part, and wherein, lamp holder includes lampholder shell, lamp holder and circuit board; Lamp body partly includes lampshade, is installed in one group of aluminium base lamp plate in the lampshade, evenly is scattered in cylindric; The LED light-emitting component is placed on the described aluminium base lamp plate, described garden lamp also comprises a convection current mechanism, an internal tooth aluminium section bar radiator and a convection current device by the medial surface that is arranged on aluminium base are formed, and described convection device is installed in the medium position that lamp holder surrounds corresponding to this radiator.
As further improvement, described circuit board is arranged on the glass plate, and this plate is fixed on the lampholder shell, is connected with the aluminium base lamp plate.
As further improving, described convection device can be fan, is built in the lampholder shell.
As further improving, described convection device can be the active heat removal device, is built in the lampholder shell.
The garden lamp of this structure leads out the heat of radiator derivation another section from section bar because load onto initiatively heat loss through convection mechanism, accelerates heat radiation, has improved radiating efficiency, guarantees luminous efficiency and the service life of LED.In addition, use PCB glass plate to be connected with aluminium base, design circuit replaces original line connecting circuit on the glass plate, such connected mode, and assembling is simple, and is solid and reliable, saves time, and saves the space.

The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further details.
As shown in Figure 1, 2, a kind of LED garden lamp of the present utility model is made up of lamp holder 1 and connected lamp body part 3, and lamp holder includes lampholder shell, lamp holder and circuit board; Lamp body partly includes lampshade 2, is installed in one group of aluminium base lamp plate 13 in the lampshade, and in best specific embodiment, this lamp plate has eight, can certainly be other quantity, evenly is scattered in cylindric; The LED light-emitting component is placed on the described aluminium base lamp plate, as shown in Figure 4, the medial surface of described aluminium base is provided with internal tooth aluminium section bar radiator 14, lamp holder also is provided with convection device 11 corresponding to the medium position that this radiator surrounds, this radiator 14 and convection device 11 have constituted the convection mechanism of this garden lamp, accelerate flowing of radiator ambient air, accelerate heat radiation, improve radiating efficiency.Described circuit board is arranged on the glass plate 12, and as shown in Figure 3, this plate is fixed on the lampholder shell, is connected with aluminium base lamp plate 13.Convection device can be any device of the prior art that fan maybe can be realized the active heat removal function.In most preferred embodiment, adopt fan to be built in the lampholder shell with structure to the blowing of aluminium section bar radiator.
The above; it only is preferred embodiment of the present utility model; not in order to restriction the utility model, every foundation technical spirit of the present utility model to any trickle modification that above embodiment did, be equal to and replace and improve, all should be included within the protection domain of technical solutions of the utility model.
