Particularly, the waterproof performance of the LED wall washing lamp is improved. The LED wall washing lamp comprises a shell, an LED lamp board fixedly arranged inside the shell, and optical lenses arranged on the LED lamp board, wherein each optical lens is formed by integrally molding a light-transmitting material and comprises a lens body and a bracket base; the outer outline of the lens body is cylindrical and each lens body is provided with an inner cavity; the bracket base is located at the lower end of each lens main body and is annular; the structure of the inner cavity of each lens body is as follows: a reversed cone is arranged from the upper surface of a cylinder to a support base in a direction from top to bottom; a containing cavity for placing LED light sources is arranged at a tapered top of the cone; a plurality of the optical lenses are respectively buckled on a plurality of the LED light sources on the LED lamp board, namely the LED light sources are rightly placed in the containing cavity of the cone and are tightly contacted with the bracket base and a bottom substrate of the LED lamp board; and sealing glue with the certain thickness is filled into a space formed by the LED lamp board in the shell, the optical lenses and the side wall of the shell.

Description

The LED wall lamp

Technical field

The utility model relates to the illumination optical technical field, and particularly a kind of LED wall lamp specifically is that the water proofing property of LED wall lamp is improved.

Background technology

The application of LED illumination is more and more wider, becomes the green energy conservation product of future generation of replace incandescent and electricity-saving lamp.The LED wall lamp is exactly a kind of mode of using lighting wherein.The LED wall lamp as its name suggests, lets light wash metope as water, mainly also is the usefulness that is used for doing the building decoration illumination, is used for sketching the contours the profile of heavy construction in addition.Because its profile is a strip, also there is the people that it is called the LED line lamp.

The LED wall lamp mainly comprises LED lamp plate, optical system and the shell of bar shaped.Because the application scenario of LED wall lamp is at the outdoor architecture thing, the LED wall lamp need reach favorable protection property.Existing LED wall lamp is for taking into account optical effect and protection effect, and common safeguard structure that adopts and optical system are comparatively complicated: or adopt complicated once light-distribution optical system, otherwise employing adds a totally enclosed cover structure.These 2 kinds of schemes can increase the volume and the cost of light fixture.

The utility model content

Therefore, to above-mentioned problem, the utility model proposes a kind of LED wall lamp, mainly its optical lens is improved, and the requirement of shelter of sealing is satisfied in simple and effective realization, and the optics requirement of the secondary light-distribution that is suitable for throwing light on.

For realizing above-mentioned technical problem, the solution that the utility model is taked is:

A kind of LED wall lamp comprises shell, is fixedly arranged on the LED lamp plate in the shell and is located at the optical lens on the LED lamp plate.Wherein, Described optical lens is the one-body molded formation of light-transmitting materials; Comprise that outline is cylindric and the lens body of band inner chamber and the bracket base that is positioned at the annular of lens body lower end; The inner-cavity structure of lens body is: on the direction from top to bottom of bearing base, have an inverted cone by the cylinder upper surface, the vertex of a cone of cone forms the cavity volume of an arrangement led light source; Described a plurality of optical lenses are buckled in respectively on a plurality of led light sources on the LED lamp plate; Be that led light source just is placed in the cavity volume of above-mentioned cone and above-mentioned bracket base closely contacts with the bottom substrate of LED lamp plate, and certain thickness fluid sealant is injected in the space of LED lamp plate, optical lens and side wall of outer shell in described shell.

Further, be positioned at this cavity volume on the conical surface of described cone and have support chip on every side.

Further, described support chip is an arc plate, and is positioned at the relative both sides of cavity volume symmetry.

The LED wall lamp of the utility model adopts integrated optical lens; Well satisfy the requirement of wall lamp secondary light-distribution; Only need that simultaneously a plurality of optical lenses are buckled in the fluid sealant that reinjects on a plurality of led light sources on the LED lamp plate respectively and can realize reliable sealing effect, satisfy the protective requirement of wall lamp.The utlity model has simple in structure, with low cost, protective and the optical advantage of taking into account.

The specific embodiment

Combine accompanying drawing and specific embodiment that the utility model is further specified at present.

To shown in Figure 5, a kind of LED wall lamp comprises shell 4, is fixedly arranged on the LED lamp plate 2 in the shell 4 and is located at the optical lens 1 on the LED lamp plate 2 with reference to figure 4.Consult Fig. 1 to shown in Figure 3; Wherein said optical lens 1 is the one-body molded formation of light-transmitting materials; Comprise that outline is cylindric and the lens body 10 of band inner chamber and the bracket base 20 that is positioned at the annular of lens body 10 lower ends; The inner-cavity structure of lens body 10 is: on the direction from top to bottom of bearing base, have an inverted cone 30 by the cylinder upper surface, then cylinder upper surface 101 is the optical lens exiting surface, and the conical surface 303 of cone 30 is a reflecting surface; In order to LED light is assembled toward the geometric center of lens body 10, the vertex of a cone of cone 30 forms the cavity volume 301 of an arrangement led light source 3; Described a plurality of optical lenses 1 are buckled in respectively on a plurality of led light sources 3 on the LED lamp plate 2; Be that led light source 3 just is placed in the cavity volume 301 of above-mentioned cone 30 and above-mentioned bracket base 20 closely contacts with the bottom substrate of LED lamp plate 2, and the space injection fluid sealant 5 of the LED lamp plate 2 on described shell 4, optical lens 1 and side wall of outer shell.

Preferably, be positioned at cavity volume 301 on the conical surface 303 of described cone 30 and have support chip 302 on every side.Can more conveniently stably this optical lens 1 be fixed on the led light source 3 of LED lamp plate 2 through being provided with of support chip 302.Preferred, described support chip 302 is arc plates, and is positioned at the relative both sides of cavity volume 301 symmetries.The support chip of circular arc type and the profile of led light source are more identical, and only needing 2 can fixedly secure.

Although only come specifically to show and introduced the scheme of the utility model above with a most preferred embodiment structure; But the those skilled in the art should be understood that; In the spirit and scope of the utility model that does not break away from appended claims and limited; Can make various variations to the utility model in form with on the details, be the protection domain of the utility model.
