Description

A kind of great power LED wall lamp

Relate to the field

The utility model relates to a kind of ligthing paraphernalia, and especially a kind of is light source with light emitting diode (LED), has the wall lamp of excellent heat dispersion performance.

Background technology

Light emitting diode (LED) as internationally recognized the 4th generation green illumination light source, have energy-saving and environmental protection, an advantage such as the life-span is long, light efficiency is high, radiationless, shock resistance, in today of global energy growing tension, and get most of the attention.But in the use of reality, problems such as the heat radiation of LED light fixture, cost height are restricting the large-scale application of LED always and are popularizing, and heat dissipation problem especially is directly connected to the performances such as brightness, light decay, stability, service life of LED light fixture.

At present, for solving the heat dissipation problem of LED, domestic many producers and engineers and technicians have done deep research on the one hand at this.Wherein, a kind of heat dissipation LED wall lamp (see figure 1) is disclosed in publication number is the patent documentation of CN201326955Y, it includes body 1, radiator 2, led light source 3 and base 4, wherein, the tubular structure that described body 1 does not seal for sidewall, described body 1 stretches out on the position that this sidewall does not seal and is the described radiator 2 of the column that two ends communicate, and described led light source 3 is fixed in the chamber of described body 1, and described body 1 is fixed in described base 4.In this patent, be manufactured with radiator 2 in the sidewall of body 1, be formed with fin 21 in the radiator 2, can realize the gapless efficient transmission of heat.After led light source 3 was fixed in the chamber of body 1, the heat transferred body 1 that is produced was dispelled the heat by the fin 21 of column, thereby the heat of led light source 3 is derived, to reduce the optical attenuation of light fixture.

But, in above-mentioned patent,, needing the exploitation and composition mould because body 1 needs to adopt extrusion process to be shaped, cost is higher.Simultaneously, on heat dispersion, though the heat that led light source 3 produces can efficiently transmit, the quantity and the area of fin 21 are limited.If fin 21 is positioned at the inside of body 1, that then can't make is comparatively frivolous, causes the integral body of body 1 heavier; If fin 21 is positioned at body exterior, will use, the overall appearance of wall lamp be impacted so.Therefore, the radiator cost of manufacture height in this patent, area of dissipation is limited, weight is heavier, can't satisfy the heat radiation requirement than great power LED.

The specific embodiment

From the schematic diagram of Fig. 2 as can be known, the outward appearance of present embodiment is a cylinder type, and whole lamp is fixed on the installation place by the side of base a7.Be fixed with lampshade a1 and printing opacity bucket a2 respectively in the upper end of wall lamp, wherein printing opacity bucket a2 is positioned at the outside of lampshade a1.Be manufactured with loophole a21 on printing opacity bucket a2 side, the light that inside is sent can form different hot spots.In use, lampshade a1 integral body is luminous if desired, and when not needing to form hot spot, can remove printing opacity bucket a2 in the lampshade a1 outside.

Lampshade a1 is that conical, circular, rectangle or other are irregularly shaped, to form different wall lamp shape and style.Lampshade a1 generally adopts glass, plastic or other material to make, and on the one hand, can light transmission better, the light losing that sees through be less; On the other hand, have stronger hardness, can play certain protective action lamp interior.

At the end portion of wall lamp, base a7 side is connected with fin a61.Fin a61 adopts the radial surface that is distributed in radiator, in the forming process of fin a61, can adopt the lower end thick, the transmission that the thin structure in upper end improves heat; Simultaneously, can also be made into uneven, striped,, improve radiating efficiency to increase the contact area of fin a61 and air on the surface of fin a61.

In the profile of Fig. 3, we as can be seen, present embodiment is made up of lampshade a1, printing opacity bucket a2, cover plate a3, led light source a4, substrate a5, radiator a6 and base a7 etc.Wherein, led light source a4 is fixed in the end of substrate a5, and printing opacity bucket a2 is fixed on the substrate a5 by helicitic texture, printing opacity bucket a2 is positioned at the periphery of lampshade a1, both combine closely, and form an airtight space with substrate a5, and led light source a4 is positioned at this confined space.The upper fixed of led light source a4 has cover plate a3, and the central authorities of cover plate a3 are provided with a through hole, and through hole is more than or equal to the illuminating part size of light source, in installation corresponding to the illuminating part of led light source a4.By cover plate a3 is installed, can be good at protecting being electrically connected of led light source a4, and can not have influence on the bright dipping of light source.

In the fixation procedure of led light source a4, can between led light source a4 and substrate a5, fill Heat Conduction Material, as heat-conducting cream etc.,, improve heat conductivility to increase contact area between the two.On fixed form, can adopt screw, buckle, welding etc. that led light source a4 is combined closely on the surface of substrate a5.Wherein, led light source a4 is single-chip package or the integrated encapsulation of multicore, and the wavelength of light source can be visible or black light wave band, or mixed light.

Substrate a5 is a circular configuration, and the smoothness on surface can be improved through polishing or coating film treatment in the surface, to increase the reflecting effect of light.The shape of substrate a5 and printing opacity bucket a2, radiator a6 mate mutually, adopt highly heat-conductive materials such as metal, alloy or pottery to make, and have good thermal conductivity.Substrate a5 closely connects radiator a6 by screw thread or alternate manner, makes the quick transmission that forms heat between the two.

At the substrate a5 other end close-fitting radiator a6 is arranged, radiator a6 then is fixed on the base a7.By the distribution of substrate a5 two ends tight fixedly printing opacity bucket a2 and radiator a6, the heat that led light source a4 is produced can pass to printing opacity bucket a2 and radiator a6 fast, because both directly expose in air, not only area of dissipation is big, efficient is high, also has with low cost, advantages such as structure slim and graceful, good looking appearance.

Fig. 4 is the three-dimensional exploded view of present embodiment, and in the drawings, lampshade a1 is a hollow cylinder, lower ending opening, and the upper end is provided with seal cover, and seal cover can be installed before lampshade a1 is installed on printing opacity bucket a2, or installed afterwards again.Be fixed with printing opacity bucket a2 in the periphery of lampshade a1, on printing opacity bucket a2 side and/or top, be distributed with bar shaped, circle or other erose loophole, to form the required various light of illumination.Zheng Ti illumination if desired then can not adopted printing opacity bucket a2, only uses lampshade a1 to be fixed on the substrate a5.

Substrate a5 is metal or alloy such as copper, aluminium, or other highly heat-conductive material, is manufactured with screw and screw thread respectively on surface and side, is respectively applied for fixedly printing opacity bucket a2 and radiator a6.Led light source a4 is fixed on the substrate a5, and above led light source a4 and cover plate a3 is installed, led light source a4 is positioned at and is positioned at the confined space that is formed by substrate a5, lampshade a1 and printing opacity bucket a2 etc.

Radiator a6 closely is connected substrate a5 by screw thread, and is fixed on the base a7.Wherein radiator a6 is metal, alloy or other highly heat-conductive material extrusion modling, and monnolithic case can be cylinder, prism or other shape.Surface distributed at heat-dissipating casing a6 has radial fin a61, and the size of fin a61 and quantity can be regulated according to the needs of heat radiation, to increase area of dissipation, improves radiating effect.

Above embodiment only is a preferred version of the present utility model, and other any simple or surperficial change is all in protection domain of the present utility model.
