Abstract
The utility model discloses a kind of anti-dazzle flat lamps, including frame, light source board and light guide plate, the frame is centered around the surrounding of the light guide plate, the light source board is mounted on the side of the medial surface of the frame and the face light guide plate, the light-emitting surface of the light guide plate is equipped at least two layers of brightness enhancement film, the brightness enhancement film has prism facets and a micro-structure face, and the prism facets of the brightness enhancement film are towards the light guide plate.The light of the light source board carries out leaded light using the light guide plate, under the action of brightness enhancement film, repeatedly reduces light-emitting angle, and the light-emitting angle of flat lamp is made to reach requirement, UGR values is effectively reduced, reaches antiglare effect.The places such as drafting room, classroom can be widely used in.
Description
Technical field
The utility model is related to a kind of flat lamp, more particularly to a kind of anti-dazzle flat lamp.
Background technology
Type unified glare value UGR, the light that the lighting device for measuring in Visual Environment is sent out cause human eye not relax
The psychological parameter of suitable sense subjective response.
Present flat lamp, although having greatly improved in level of illumination, it is susceptible to glare phenomenon, light
Comfort and bad, UGR values are commonly greater than 20.As market is higher and higher to the pursuit of lighting quality, the big product of UGR values
Use scope is limited, and influences the popularization in market.
Utility model content
The utility model provides a kind of anti-dazzle flat lamp, and which overcome the deficiencies present in background technology.This practicality is new
Technical solution is used by type solves its technical problem：
A kind of anti-dazzle flat lamp, including frame, light source board and light guide plate, which is centered around the surrounding of the light guide plate, should
Light source board is mounted on the side of the medial surface of the frame and the face light guide plate, it is characterised in that：The light-emitting surface of the light guide plate is set
There is at least two layers of brightness enhancement film, which has prism facets and a micro-structure face, and the prism facets of the brightness enhancement film are towards the light guide plate.
Compared with background technology, it has the following advantages that the technical program：
The light of the light source board carries out leaded light using the light guide plate, under the action of brightness enhancement film, repeatedly reduces light-emitting angle,
The light-emitting angle of flat lamp is made to reach requirement, UGR values is effectively reduced, reaches antiglare effect.Can be widely used in drafting room,
The places such as classroom.
Description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and examples.
Fig. 1 depicts a kind of perspective exploded view of anti-dazzle flat lamp of the utility model.
Fig. 2 depicts a kind of stereoscopic schematic diagram of anti-dazzle flat lamp shown in Fig. 1.
Fig. 3 depicts a kind of sectional view of anti-dazzle flat lamp shown in Fig. 1.
Specific embodiment
Please refer to Fig. 1 to Fig. 3, a kind of anti-dazzle flat lamp of the utility model, including frame 10, light source board 20 and leaded light
Plate 30.The frame 10 is centered around the surrounding of the light guide plate 30.The light source board 20 is in strip, which is mounted on the frame
The side of 10 medial surface and the face light guide plate 30.The light-emitting surface of the light guide plate 30 is equipped with two layers of brightness enhancement film 40.The brightness enhancement film
40 have prism facets and micro-structure face, and the prism facets of the brightness enhancement film 40 are towards the light guide plate 30, and micro-structure face is as light-emitting surface.
Double-deck brightness enhancement film 40 can effectively reduce UGR values, and ensure that UGR values are not more than 16.
Diffuser plate 50 is further included, the brightness enhancement film 40 is clamped between the light guide plate 30 and the diffuser plate 50, the brightness enhancement film
40 micro-structure is facing towards the diffuser plate 50.The diffuser plate 50 can make light more uniform.
The back side of the light guide plate 30 is equipped with one layer of reflective sheeting 60.The back side of the reflective sheeting 60 is equipped with one layer of EVA foam 70.
Backboard 80 is further included, which is connected on the frame 10 and pushes down the EVA foams 70.
The frame 10 is aluminium frame.10 medial surface of frame extends internally close to the edge of 50 one end of diffuser plate equipped with lip
12, which is resisted against in the lip 12.The frame 10 is quadrangle, which is two, is symmetrical arranged
In the two-phase inner surface sides of the frame 10.The frame 10 surrounds the light source board 20, light guide plate 30, brightness enhancement film 40, diffusion from surrounding
Plate 50, reflective sheeting 60 and EVA foams 70.
Light UGR values after first layer brightness enhancement film 40 are less than or equal to 19, light UGR after second layer brightness enhancement film 40
Value is less than or equal to 16.
The above, only the utility model preferred embodiment, therefore the utility model implementation cannot be limited according to this
It is new all should still to belong to this practicality for range, i.e., the equivalent changes and modifications made according to the utility model patent range and description
In the range of type covers.
