Abstract

The utility model discloses a lampshade installation structure of an LED lighting lamp, which comprises a lampshade. The section of the lampshade is arc-shaped, the lampshade is arranged on a base, the section of the lampshade is arced, and the base is semicircular; an LED circuit board is arranged at the inner surface of the base, an outward bulge is arranged at the rim of the lampshade, a detent which is bent towards the inner side is arranged at the rim of the upper surface of the base along a bus, and the bulge of the lampshade is clamped in the clearance formed by the detent and the rim of the circuit board. The lampshade installation structure discloses that the radial mould opening can be carried out when in the injection molding, processing and forming of the lampshade, so as to overcome the disadvantage that the present lampshade can only carry out axial mould opening; besides, when in forming, multiple refraction stripes can be formed at the surface of the lampshade, so as to meet the scattering requirement of various light rays of the lighting lamp; the structure is novel, and the processing and installing are convenient.

Description

A kind of LED lighting lamp shade mounting structure

Technical field

The utility model relates to a kind of light fixture, specifically a kind of LED lighting lamp shade mounting structure easy to process, easy for installation.

Background technology

Comparatively fixed forms of seeing are clamping more between existing tubulose LED lighting lamp shade and the base, since on the lampshade with the specific (special) requirements of base wedging position, lampshade adds man-hour can only be along the axial die sinking of lampshade, radially die sinking adds lampshade and can not satisfy the requirement that has different scattering angle lampshades in same fluorescent tube at the different thickness striped of lampshade surface forming man-hour.

The utility model content

The technical problems to be solved in the utility model provides a kind of LED lighting lamp shade mounting structure easy to process, easy for installation.

For solving the problems of the technologies described above, the utility model by the following technical solutions:

A kind of LED lighting lamp shade mounting structure, comprise that the cross section is the lampshade of arc, lampshade is installed on the base, the lampshade cross section is arc, base is semicircle, in base inner surface the LED wiring board is installed, and is provided with outside projection at the lampshade edge, the base upper surface edge is provided with crooked to the inside screens along bus, and the projection of lampshade is stuck in the gap of screens and the formation of wiring board edge.

As the improvement to such scheme, convex outer surface and lampshade outer surface intersection angle are the obtuse angle.And lampshade and projection are along the lampshade integrative-structure of injection mo(u)lding radially.

Reach default scattering requirement for the ease of LED light, be provided with refraction striped on the lampshade surface along the lampshade circumferencial direction by the lampshade surface.And the refraction striped of adjacent lampshade can be as required in characteristic aspect such as shape, density arrangements and difference.

Radially die sinking during lampshade injection moulding machine-shaping that the utility model disclosed, customer service the axial defective of die sinking of existing lampshade, and when moulding, can satisfy the requirement of the various light scatterings of illuminating lamp at the multiple refraction striped of lampshade surface forming, novel structure, processing, easy for installation.

Description of drawings

Accompanying drawing 1 is the utility model embodiment overall structure schematic diagram; Accompanying drawing 2 is a present embodiment decomposing state structural representation; Accompanying drawing 3 is a present embodiment cross section structure schematic diagram; Accompanying drawing 4 is an A portion enlarged diagram in the accompanying drawing 3.

The specific embodiment

For the ease of those skilled in the art's understanding, the utility model structural principle is described in further detail below in conjunction with specific embodiment and accompanying drawing:

Shown in accompanying drawing 1～4, the LED illuminating lamp that present embodiment disclosed is whole to be tubulose, comprises the base 2 of double as thermal component, posts LED wiring board 3 at base 2 inner surfaces, and LED is fixed on the LED wiring board 3, and Transparent lamp shade 1 then is installed above base 2.

Lampshade 1 cross section is arc, base 2 cross sections are semicircle, be provided with outside projection 11 at lampshade 1 edge, base 2 top surface edge are provided with crooked to the inside screens 21 along bus, and the projection 11 of lampshade 1 is stuck in the gap of screens 21 and the formation of LED wiring board 3 edges.

For lampshade 1 can be adopted along radially die sinking form of lampshade when the injection mo(u)lding, protruding 11 outer surfaces and lampshade 1 outer surface intersection angle a are the obtuse angle.Simultaneously, be provided with along the refraction striped 12 of lampshade 1 circumferencial direction, make light by being the different angles scattering after the lampshade 1 on lampshade 1 surface.The lampshade 1 of a plurality of different refraction stripeds 12 can be set in same fluorescent tube, make whole fluorescent tube satisfy multiple light requirement.

The preferred version that the foregoing description is only realized for the utility model, and non-limiting exhaustive, and under the prerequisite that does not break away from the present utility model design, any conspicuous replacement is all within the utility model protection domain.
