The yard lamp has excellent functions of heat radiation and insect prevention and is fine in lighting effect and long in service life.

Description

A kind of garden lamp

Technical field

The utility model belongs to technical field of lamps, is specifically related to a kind of garden lamp with heat radiation and insect protected function.

Background technology

Existing LED lamp radiator all is to cover on the LED, only rely on the cross-ventilation of face of land run-in index and take away heat, and the lamp chamber all is all-sealed that this mode is unfavorable for effective performance of heat sinking function, has quickened the ageing process of LED lamp.Led light source under fin because the characteristic of LED rising angle; It is bright visible having only less relatively zone of exiting surface after night is luminous; With regard to attractive in appearance; Well-designed lamp holder major part is to hide sightlessly in the dark, and this becomes the shortcoming that garden lamp self is viewed and admired function demonstration.

The utility model content

To the problem that prior art exists, the purpose of the utility model is to design the technical scheme that a kind of garden lamp is provided, and this garden lamp has good heat sinking function and insect protected function, and good illumination effect, long service life.

Described a kind of garden lamp comprises lamp stand, it is characterized in that described lamp stand top is fixedly connected radiator; Fixedly install lampshade on the radiator; The middle part of the radiator in the described lampshade is provided with heat-conducting layer, fixedly installs the aluminium base that has LED on the heat-conducting layer, and aluminium base fixedly installs lens outward.

Described a kind of garden lamp is characterized in that described lamp stand is S shape structure, the thick hollow taper structure or the hollow cylindrical structure in thin bottom, upper end of hollow.

Described a kind of garden lamp is characterized in that described radiator bottom close-fitting inner sleeve, and the inner sleeve lower end is embedded in the lamp stand top.

Described a kind of garden lamp is characterized in that described radiator comprises the cooling base at middle part, fixedly installs one on the cooling base and forms radial fin.

Described a kind of garden lamp is characterized in that described lampshade is fixedly connected with radiator through the fastening lampshades compressing tablet that is provided with.

Described a kind of garden lamp is characterized in that described cooling base top is planar structure, frustum cone structure or terrace with edge structure, and described planar structure or round platform, terrace with edge shape body structure surface are provided with heat-conducting layer.

Described a kind of garden lamp is characterized in that fixedly installing fly net on the described fin.

Above-mentioned a kind of garden lamp, simple in structure, reasonable in design; The utility model places radiator under the led light source, fin be to around divergent shape, be beneficial to the up and down generation of convection current of fin surrounding air; Thereby reach the exchange of cold and hot air inside and outside the lamp; The fin that is exposed to outside the lampshade still can effectively utilize the air of PARALLEL FLOW to take away the part heat, has effectively strengthened radiating effect, thereby has reached the effect that has strengthened LED service life; On the basis that guarantees cold and hot air exchange, fly net is set, above fin with the overall appearance that prevents that winged insect and dust from getting into influences lamp; For guaranteeing that irradiate light satisfies the requirement of garden lamp illumination; Led light source add lens that harness has a waterproof action with light to around refraction; Have multiple mode can make light according to the actual illumination demand, as the modes such as angle that install lens, reflector, change radiator LED installation site additional make the LED beam angle meet demand to the irradiation of the direction of needs.The utility model makes lamp body self have good sight satisfying form being apparent in the curtain of night of nature under light that effectively makes graceful lamp holder on the basis of illumination functions, is a perfect adaptation of function and form.

The specific embodiment

Further specify the utility model below in conjunction with Figure of description.

Embodiment 1

Like Fig. 1,2, shown in 3 and 4; A kind of garden lamp comprises the lamp stand 7 of the S shape structure that thin lower end, the upper end of hollow is thick; Lamp stand 7 tops have fixedly installed radiator 5; Radiator 5 comprises the cooling base 501 at middle part, and is fixedly installed on one group of fin 502 on the

cooling base

501, and 502 one-tenth of fin are radial around being arranged on the cooling base 501.The close-fitting socket is provided with inner sleeve 6 in the cooling base 501, and inner sleeve 6 lower ends are embedded in lamp stand 7 tops, and inner sleeve 6 is fastening through screw 8 again with lamp stand 7, so just radiator 5 and lamp stand 7 has been fixed.

Cooling base 501 upper ends are planar structure, and heat-conducting layer 10 is set on its planar structure, and heat-conducting layer 10 is made up of Heat Conduction Material.Fixedly install the aluminium base 9 that has LED on the heat-conducting layer 10, the aluminium base 9 outer lens 2 that fixedly install.Fixedly installed lampshade 1 through the fastening lampshades compressing tablet 4 that is provided with on the fin 502.After lampshade 1 was set, fin 502 upper ends were encapsulated in the lampshade 1, and fin 502 lower ends are exposed to the outside of lampshade 1, realized heat loss through convection up and down.In order to reach vermins-proof effect, on fin 502 upper surfaces, one deck fly net 3 is set.

Lamp stand also can adopt the pipe or the hollow straight tube of the thick pyramidal structure in thin bottom, upper end among the embodiment 1.

Embodiment 2

Like Fig. 5, shown in 6 and 7, a kind of garden lamp changes the structure of cooling base 501 in the radiator 5 on the architecture basics of embodiment 1.Frustum cone structure or terrace with edge structure are arranged in cooling base 501 upper ends.On the end face of cooling base 501 upper end frustum cone structures or terrace with edge structure and inclined-plane, heat-conducting layer 10 is set, is provided with the aluminium base 9 of LED on the heat-conducting layer 10.Like this be arranged so that the LED exiting surface to around the irradiation, end face is provided with a spot of LED and plays the parergon effect.Other structure is all identical with embodiment 1 in the present embodiment, repeats no more.

Shown in the above and the figure only is the preferred implementation of the utility model.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model principle, can also make some modification and improvement, these also should be regarded as belonging to the protection domain of the utility model.
