Description

A kind of point-source light band

Technical field

The utility model relates to the technical fields of lighting fixtures of display frame, and in particular to a kind of point-source light band.

Background technique

The display frame that exhibition advertisement etc. uses usually requires lighting apparatus and provides illumination, and existing display frame shines Bright equipment mostly uses greatly the light bar of point light source, from outside in terms of the visual angle of spectators or pedestrian, to show that picture can show multiple light There is the shadow region at illumination dead angle between hot spot, influence ornamental value in spot, and if using area source, need the rule of customized fixation Lattice, with high costs, heavier-weight and versatility is poor, therefore urgently improve.

Utility model content

In order to solve the above technical problems, being able to achieve the purpose of this utility model is to provide a kind of point-source light band without dead Angle illumination.

To achieve the above object, a kind of point-source light band of the utility model, including the light bar with LED light, the LED The periphery of lamp is arranged with the lampshade for making divergence of beam, and the lampshade includes the cover for referring to cyclic structure, and the cover, which is equipped with, to be lacked Mouthful, the cover uses material with certain deformability and transparent, keeps the size of notch adjustable；The cover is along it Arc groove circumferentially is offered, connection sheet is plugged in the arc groove, the material of the connection sheet is identical as cover, described to lack Arc groove is divided into two parts by mouth.

Preferably, the cover is using acrylic or polycarbonate or thermoplastic polyurethane elastomer rubber.

Preferably, the light bar is equipped with the card slot being clamped for cover.

Preferably, the arc groove is equipped with the limited block for preventing connection sheet to be detached from, and the both ends of the connection sheet are equipped with curved Head.

Preferably, the end of the cover is removably connected with the cover.

Preferably, the cover is snapped connection with cover.

Alternatively, the cover is threadedly coupled with cover.

The utility model compared with prior art, the beneficial effect is that:

Lampshade is arranged outside LED light, lampshade includes the transparent cover for referring to cyclic structure, the point light source that such LED light provides Light can by cover then dissipate, when having multiple LED light or multiple light bar, apparent shade will not be generated between point light source Region realizes no blind spot lighting；Cover is equipped with notch, and cover uses the material with certain deformability, thus Keep the size of notch adjustable, so that it is adapted to the LED light of plurality of specifications, either cylindrical, it is also possible to other shapes Shape；

In the arc groove interpolation contact pin in succession that cover opens up, in this way when cover to be sheathed in larger-size LED light, Notch occurs and larger, at this time connection sheet can be with fill up the gap at, prevent light from overflowing from indentation, there and influencing whole illumination Effect.

Specific embodiment

By the technology contents of the utility model are described in detail, construction feature, are reached purpose and efficacy, reality is hereby enumerated below It applies example and attached drawing is cooperated to be explained in detail.

In the description of the present invention, it should be understood that term " center ", " longitudinal direction ", " transverse direction ", "front", "rear", The orientation or positional relationship of the instructions such as "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outside" is based on attached drawing institute The orientation or positional relationship shown, is merely for convenience of describing the present invention and simplifying the description, rather than indication or suggestion is signified Device or element must have a particular orientation, be constructed and operated in a specific orientation, therefore should not be understood as to this is practical The limitation of novel protected range.

The utility model provides a kind of point-source light band, including the light bar 2 with LED light 1, the periphery of the LED light 1 It is arranged with the lampshade for making divergence of beam, the lampshade includes the cover 3 for referring to cyclic structure, and the cover 3 is equipped with notch 4, described Cover 3 keeps the size of notch 4 adjustable using having certain deformability and transparent material；The cover 3 is along its circumferential direction Arc groove 5 is offered, connection sheet 6 is plugged in the arc groove 5, the material of the connection sheet 6 is identical as cover 3, described Arc groove 5 is divided to for two parts by notch 4.

By using above-mentioned technical proposal, lampshade is arranged outside LED light 1, lampshade includes the transparent cover for referring to cyclic structure 3, then the light for the point light source that such LED light 1 provides can be dissipated by cover 3, when having multiple LED light 1 or multiple light bar 2 When, apparent shadow region will not be generated between point light source, that is, realize no blind spot lighting；Cover 3 is equipped with notch 4, and cover 3 is adopted With the material with certain deformability, thus make the size of notch 4 adjustable, to be adapted to the LED light of plurality of specifications 1, either cylindrical, it is also possible to other shapes；

In 5 interpolation of arc groove that cover 3 opens up contact pin 6 in succession, cover 3 is being sheathed on larger-size LED light 1 in this way When upper, notch 4 occur and it is larger, at this time connection sheet 6 can be with fill up the gap 4 at, prevent light from overflowing and influencing whole from notch 4 The illuminating effect of body；The specific principle of luminosity and structure of light bar 2 use the prior art, and details are not described herein again.

Preferably, the cover 3 is using acrylic or polycarbonate or thermoplastic polyurethane elastomer rubber.

By using above-mentioned technical proposal, acrylic or polycarbonate or thermoplastic polyurethane elastomer rubber these three materials Material all has certain deformability and transparency is higher, the direct socket with LED light 1 may be implemented, and 4 size of notch can lead to Deformation adjustment is crossed, other qualified materials can also be used.

Preferably, the light bar 2 is equipped with the card slot being clamped for cover 3.

By using above-mentioned technical proposal, card slot is used to guarantee that cover 3 to be contacted with the good of LED light 1, is beneficial to prevent cover Body 3 falls off from LED light 1.

Preferably, the arc groove 5 is equipped with the limited block for preventing connection sheet 6 to be detached from, and the both ends of the connection sheet 6 are equipped with Elbow.

By using above-mentioned technical proposal, limited block deviates from distance by abutting the maximum of limitation connection sheet 6 with elbow, can To prevent connection sheet 6 from falling off out of arc groove 5.

Preferably, the end of the cover 3 is removably connected with the cover.

By using above-mentioned technical proposal, the cover further prevents light from directly projecting from LED light 1, is beneficial to prevent Hot spot is generated, the cover is preferably set as band gap structure, and uses material identical with cover 3.
