Abstract

The utility model discloses a single-side wide-width LED (light-emitting diode) grid lamp, which comprises a lamp bracket, a lamp holder, a light guide plate, and an LED lamp module. The side surface of the light guide plate is arranged corresponding to the LED lamp module; and both the light guide plate and the LED lamp module are arranged in the lamp holder. The single-side wide-width LED grid lamp is characterized in that the LED lamp module is arranged at the single side of the lamp holder; and the inside of the light guide plate is provided with a corresponding reflection curve. Design of arranging the LED lamp module at the single side eliminates weak zones of beams; the light guide plate can be used for leading the glaring of the LED lamp module to be uniform and gentle; moreover, the single-side wide-width LED grid lamp can satisfy lighting intensity requirements.

Description

One-sided wide cut LED grid lamp

[technical field]

The utility model relates to the LED indoor illumination, relates in particular to a kind of wide cut grid lamp.

[background technology]

As everyone knows, so-called LED is meant light emitting diode, LED develops new type light source rapidly as a kind of present extensive use, energy-conservation, efficient, advantages such as volume is little, the life-span is long, response speed is fast, driving voltage is low, shock resistance brilliance have been compared with conventional light source, enlarge industry size, market share thereby can develop rapidly, the industry tendency leads under, its technology is also being brought in constant renewal in and in-depth.

From traditional application, generally be some LEDs chip portfolios together, constitute LED lamp bar or LED lamp plate, making becomes indoor or outdoor large field lighting equipment, the related wide cut grid lamp of the utility model is a kind ofly by LGP the wide area light that single-row or single light is drawn into wide cut to be shone out, existing wide cut grid lamp is because the restriction of the luminous intensity of chip, can not cover so wide amplitude, so all be all to arrange led chip in the both sides of wide cut grid lamp, be respectively LGP of led chip configuration of both sides then, though the product of this design can make the luminous intensity of the grid lamp of certain wide cut reach requirement, but because the centre is the intersection of two LGPs, so just caused the existence of a light reduction band, the promptly visible significantly centre joint of dim light of people's naked eyes, then to exist huge defective also to influence attractive in appearance for product.

[summary of the invention]

The utility model provides a kind of dull thread reduction band, whole bright dipping evenly soft for addressing the above problem, and can satisfy the one-sided wide cut LED grid lamp that intensity of illumination requires.

The technical scheme that the utility model addresses the above problem is: the one-sided wide cut LED grid lamp that the utility model is related, comprise lamp bracket, lamp socket, LGP, LED lamp module, the side correspondence of LGP the setting of LED lamp module, described LGP and LED lamp module are all packed in the lamp socket, it is characterized in that, described LED lamp module is arranged on the one-sided of lamp socket, and the inside of LGP has corresponding reflecting curved surface.

Described LED lamp module can be that the above led chip arrangement of row forms;

The reflecting curved surface of described LGP is with the direction at the corresponding LED lamp of concave face module place;

Described LGP is to adopt the Ya Like of high-transmission rate to be made, and leaves one section sagging space at the lateral edges of LED lamp module, is in order to hold the led chip setting.

The beneficial effects of the utility model are: adopt the one-sided LED lamp module design that is provided with, eliminated light reduction band; The use LGP can be evenly soft with the bright dipping of LED lamp module, and can satisfy the one-sided wide cut LED grid lamp that intensity of illumination requires.

Fig. 1 is the utility model one embodiment diagrammatic sketch that explodes;

Fig. 2 is the utility model LGP and LED lamp module construction profile.

Among the figure: 1, lamp bracket; 2, lamp socket; 3, LGP; 4, LED lamp module; 5, reflecting curved surface.

[specific embodiment]

In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.

The one-sided wide cut LED grid lamp that the utility model is related, comprise lamp bracket 1, lamp socket 2, LGP 3, LED lamp module 4, the side correspondence of LGP 3 LED lamp module 4 and is provided with, described LGP 3 and LED lamp module 4 are all packed in the lamp socket 2, it is characterized in that, described LED lamp module 4 is arranged on the one-sided of lamp socket 2, and the inside of LGP 3 has corresponding reflecting curved surface 5.

As shown in Figure 2, the reflecting curved surface 5 that described LGP 3 is had is the free-form surface lens that have of a kind of Ya Like material that is made by injection molding process, described " free form surface " is well known to a person skilled in the art, and is generally understood as any curved surface that can or cannot express with mathematical formulae.LGP 3 is to adopt the Ya Like of high-transmission rate to be made, and LGP 3 is in some space of sinking of one side, and this space is to be provided with in order to hold LED lamp module 4; Have free form surface 5 in the inside of LGP 3, free form surface 5 is with the direction at the corresponding LED lamp of side module 4 places of its depression.

In assembling, earlier LED lamp module 4 and LGP are assembled, the sagging space that allows LED lamp module correspondence LGP 3, the light emission of sending from LED lamp module 4 enters into LGP, reflexes to free form surface 5 and is reflected by free form surface 5 then, and final irradiation is come out.

Described LED lamp module 4 can be that the above led chip arrangement of row forms; The combination led module combination of the detachable formula of the constant current of adopting.

Because LED lamp module of the present utility model is one-sided setting, then heating region mainly concentrates on a side, an other side temperature is obviously lower, so just provide willing energy for the design of optimizing structure, heat-radiating substrate only needs a side setting, an other side has been reserved the space and can be designed as the space of settling detachable power pack, and product structure is arranged reasonably optimizing more like this.

The wide cut of lamp can be provided with arbitrarily as required, only need the columns of simple change led chip and the mould that is used for injection moulding lens to get final product.
