The LED lamp with the structure has the problems of soft luminous surface, low light emitting efficiency, overlarge lamp body size and the like, and a point light source with obvious brightness (uneven brightness) is easily formed on the light-transmitting cover.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a to the not enough of existence among the prior art, provide the rectangular lamp of LED.

The utility model discloses a realize through following technical scheme: LED rectangular lamp, including the lighting fixture, one side of lighting fixture sets up to the opening be provided with on the opening and seal open-ended printing opacity cover the lighting fixture internal fixation has the LED lamp area that is the bar, the vertical interval distribution in LED lamp area has multiunit LED lamp body, its characterized in that: the inner side wall of the light-transmitting cover is provided with a plurality of groups of concave cambered surfaces, and each group of cambered surfaces extend along the width direction of the light-transmitting cover and are connected with each other.

In the technical scheme, all the cambered surfaces are uniformly distributed.

In the above technical solution, the projection position of the point light source of each LED lamp body in the direction of the light transmissive cover passes through the lowest point of the arc surface portion.

In the technical scheme, the distance between the point light source of the LED lamp body and the plane of the outer side wall of the light-transmitting cover is 1.5mm to 4.5 mm.

In the technical scheme, the light-transmitting cover is directly doped with the light diffusion material.

In the above technical solution, the light diffusion layer made of a light diffusion material is directly disposed on the outer surface of the light-transmitting cover.

The utility model discloses following beneficial effect has: the utility model discloses the light that sends from the LED lamp body in the product, at first through the structure back that forms between each interconnect's the cambered surface, take place reflection and refraction simultaneously for light can be jetted out with the mode that many beams light mixes mutually, and the effectual light spot problem of eliminating the LED lamp through above-mentioned structure, in addition, this application makes needn't have too big distance that sets up between LED lamp body and the printing opacity cover, this makes whole product thickness can be dwindled greatly, and the effectual luminous efficiency who improves lamps and lanterns.

Detailed Description

The invention will be described in further detail with reference to the following detailed description and accompanying drawings: referring to fig. 1 to 5, the LED strip lamp includes a lamp holder 1, one side of the lamp holder 1 is provided with an opening 10, the opening 10 is provided with a light-transmitting cover 2 for sealing the opening 10, a strip-shaped LED strip 3 is fixed in the lamp holder 1, a plurality of groups of LED lamp bodies 30 are longitudinally distributed at intervals in the LED strip 3, a plurality of groups of concave arc-shaped portions 20 are arranged on the inner side wall of the light-transmitting cover 2, each group of arc-shaped portions extends along the width direction of the light-transmitting cover 2, the arc-shaped portions 20 are connected with each other, and the arc-shaped portions 20 are uniformly distributed.

The light that sends in this application from LED lamp body 30 at first through the structure back that forms between each interconnect's the cambered surface, takes place transmission and refraction effect for light can be jetted out with the mode of diffusion, and the effectual light spot problem of eliminating the LED lamp through above-mentioned structure, makes to send more even and soft light on the printing opacity cover 2.

In this application, preferably, the projection position of the point light source 200 (here, equivalent point light source) of each LED lamp body 30 in the light-transmitting cover direction passes through the lowest point 100 of the arc surface portion, so that the point light source of the LED lamp body can uniformly project light to both sides along the lowest point of the arc surface as an axis.

Distance between pointolite of LED lamp body 30 to the printing opacity cover lateral wall plane is at 1.5mm to 4.5mm, in this embodiment, above-mentioned distance sets up to 3mm, owing to set up the cambered surface structure of indent in printing opacity cover 2's inboard, this makes pointolite of LED lamp body needn't set up too big distance between the printing opacity cover, alright realize that light can be followed the even projection of printing opacity cover, above-mentioned distance sets up between traditional LED lamp body and the printing opacity cover and needs to exceed 8mm, this makes the thickness of whole long lamp of LED difficult to be reduced.

Preferably, the light-transmitting cover 2 is directly doped with a light diffusion material for enhancing the light diffusion performance of the whole light-transmitting cover 2, and in addition, another equivalent mode can also be adopted in the application, namely, a light diffusion layer 21 made of the light diffusion material is directly arranged on the outer side surface of the light-transmitting cover 2, and compared with the mode of directly doping the light diffusion material, the mode has the advantage of saving the light diffusion material more, and in addition, the light diffusion capability is greatly increased.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The foregoing embodiments and description of the present invention have been provided only for the purpose of illustrating the principles of the present invention, and various changes and modifications may be made without departing from the spirit and scope of the present invention, for example, although the embodiments show a uniform distribution of the curved surface portions 20, those skilled in the art will appreciate that the curved surface portions may be non-uniformly distributed as required. All such variations and modifications are intended to be within the scope of the claimed invention.
