Description

A kind of two-way illumination LED wall lamp

Technical field

The utility model relates to the LED lighting engineering, specifically, relates to a kind of LED wall lamp that can two-way illumination.

Background technology

The LED wall lamp is soft with its source light, the brightness height, life-span is long, energy consumption is low, to advantages such as the color representation power on irradiation thing surface are strong, generally be used for greening Landscape Lighting, the illumination of building flooring, indoor local lighting, billboard lighting, public place of entertainment atmosphere illumination, guardrail or viaduct sidewall and thrown light on.

Common LED wall lamp is a plurality of lamp holders to be arranged be fixed on the support, and a LED illuminator is housed on each lamp holder.The whole light-emitting area of light fixture adds a transparent face mask.Therefore such wall lamp can only illuminate in one direction owing to have only a light-emitting area, and its irradiation area is very limited.When a plurality of directions require to throw light on simultaneously, just need to increase the quantity of wall lamp.Certainly will cause cost to rise like this, the light fixture utilization rate is not high, adding face shield also makes light efficiency reduce, radiating effect is also undesirable, thereby influence the life-span of light fixture, the projected area of adding traditional wall lamp is excessive, when being installed in the high building use, it is excessive to cause the wind of light fixture to carry, and influences the extraneous adornment effect of building integral body.

The utility model content

For solving the problems of the technologies described above, the utility model provides a kind of two-way illumination LED wall lamp, can satisfy the illumination needs of both direction simultaneously, has improved the utilization rate of light fixture, has reduced production cost.

For achieving the above object, the utility model by the following technical solutions:

A kind of two-way illumination LED wall lamp, comprise the support of at least two pixel pipe units, fixedly connected pixel pipe unit, it is characterized in that: described pixel pipe unit comprises radiator, be installed in the wiring board that the LED illuminator is housed on its of the relative both sides of radiator, the mounting base that is used to connect radiator and support.

Because each pixel pipe unit can be realized the needs of two-way illumination simultaneously on the both direction LED illuminator being installed all relatively, has improved the utilization rate of light fixture, has reduced production cost.

The technical problem that another will solve of the present utility model provides a kind of two-way illumination LED wall lamp, can effectively improve the radiating effect of light fixture, for reaching this purpose:

Described pixel pipe unit exposes in air, directly contacts with outside air;

Described radiator comprises a plurality of radiating fins that cylindrical bodies, main body outer surface are provided with vertically, and with the ring bodies of the terminal Bao Lian of described radiating fin, two end faces of described main body offer respectively for the platform of placing wiring board, like this, gap between the radiating fin and outside air have formed the passage of heat loss through convection, help heat radiation.

Also have, described pedestal is to be made into integration with radiator, and stretch out in its outside from described radiator ring bodies, and the installation bottom surface on a plane is formed on the bottom.Because pedestal and radiator are made into integration, and have avoided the influence of loose contact to radiating effect.

Described pedestal axially is being provided with through hole along radiator, forms penetrating shape structure, helps heat radiation.

The technical problem that another will solve of the present utility model provides a kind of two-way illumination LED wall lamp, and not adding face shield also can moistureproof and waterproof.

For reaching this purpose, above described LED illuminator, be covered with lens, described lens and described radiator and wiring board sealing are installed.Like this, comprise on radiator, wiring board and the wiring board the LED illuminator just by be covered with thereon lens make each independently the pixel pipe unit seal.

Also have, offer the groove that passes for the wiring board contact conductor from described radiator body end face to described base bottom surface, described groove passes the back at contact conductor and seals with colloid.

So just can realize the sealing of whole light fixture, reach the effect of moistureproof and waterproof.

In addition, owing to adopt the pixel pipe unit of above-mentioned open type structure, light fixture does not add face shield outward, has reduced the wind of light fixture under the operating position of high-altitude and has carried, thereby avoided carrying the excessive result of use that influences because of wind.

The utility model also aims to provide a kind of two-way illumination LED wall lamp, can change the direction of illumination of light according to the needs of reality use, for reaching this purpose, two kinds of implementations is arranged:

One: described all vertical with the main body axis of described radiator for two platforms placing wiring board, having one in the described lens at least is polarizing lens.The polarizing angle of these lens can design according to actual needs.

Its two: described for having at least a main body axis to be an angle in the platform of placing wiring board with described radiator.Lens adopt usual manner, and the platform that will place wiring board is made inclination, can reach the effect of polarisation equally.

The specific embodiment

Referring to Fig. 1, a kind of two-way illumination LED wall lamp of the utility model comprises a plurality of pixel pipe units 1 and the mounting bracket 2 of fixing all pixel pipe units 1.

Referring to Fig. 2～Fig. 5, pixel pipe unit 1 comprises radiator 11 (not comprising wiring board 6, LED illuminator 5 and pedestal 4 parts among the figure), is installed in the wiring board 6 that LED illuminator 5 is housed on its of radiator 11 relative both sides, the mounting base 13 that is used to connect radiator 11 and support 2.

In the present embodiment, a plurality of radiating fins 112 that radiator 11 is provided with vertically by cylindrical bodies 111, main body outer surface, and with described radiating fin 112 terminal ring bodies 113 compositions that link up that wrap, form directly the through hole 12 with the outside air heat loss through convection, two end faces of described cylindrical bodies 111 offer respectively platform 114 and 114 for placement wiring board 6 '.

In the present embodiment, pedestal 13 is made into integration with radiator 11, described pedestal 13 stretches out from the outside of the ring bodies 113 of described radiator 11, the installation bottom surface on one plane is formed on the bottom, install two reference columns 131 and an installation screwed hole 132 are set on the bottom surface, be respectively applied for when pixel pipe unit 1 is installed on the support 2 and accurately locate and installation.Described pedestal 13 axially also is being provided with through hole 12 along radiator 11.
