LED coloured plate lamp
Technical field
The utility model relates to field of light fittings, particularly relates to a kind of LED coloured plate lamp.
Background technology
The LED flat lamp is a kind of light fixture that is applied in the building indoor and outdoor lighting.Traditional LED flat lamp usually adopts with substrate as carrier and a plurality of LED spot lights are welded in the direct projection light source design of PCB substrate.But, adopt the LED flat lamp luminosity of direct projection light source design inhomogeneous, be easy to produce dazzle, and single lamp damage back is bigger to the influence of overall lamp light effect.
Along with the development of LED flat lamp, manufacturer adopts the method from LGP side incident ray, and light enters diffuser plate through LGP, penetrate through diffuser plate diffusion back, emergent ray is even, free from glare, and it is less to the influence of overall lamp light effect that single lamp damages the back.But adopt the LED flat lamp of producing from the method for LGP side incident ray to adopt the white LED lamp bar as light source usually, only can produce white light, photochromic single, can't satisfy the user to the different demands of photochromic environment.
The utility model content
Based on this, be necessary at the photochromic single problem of traditional LED flat lamp, a kind of multiple photochromic selectable LED coloured plate lamp that has is provided.
A kind of LED coloured plate lamp, comprise lamp door, LGP and LED lamp bar, described lamp door comprises four deckle boards, the adhesion of described four deckle boards head and the tail, described LED lamp bar is pasted on described deckle board towards a side at described lamp door center, described LGP be installed in the described lamp door and the side of described LGP over against described LED lamp bar, described LED lamp bar comprises substrate, a plurality of red LED chip, a plurality of green light LED chip and a plurality of blue-light LED chip, and described red LED chip, green light LED chip and blue-light LED chip are installed on described substrate at interval.
Among embodiment, also comprise diffuser plate therein, described four deckle boards respectively have the plate edge of extending to described lamp door center, and described diffuser plate is carried on the plate of described four deckle boards along last, and described LGP is arranged at described diffuser plate away from the one side on described plate edge.
Among embodiment, described LED coloured plate lamp also comprises bonnet therein, and described bonnet is installed on described lamp door away from a side on described plate edge.
Among embodiment, described LED coloured plate lamp also comprises reflective membrane therein, and described reflective membrane is arranged at described LGP away from the one side of described diffuser plate.
Among embodiment, described LED lamp bar has 4, is pasted on described four deckle boards respectively towards a side at described lamp door center therein.
Among embodiment, described LGP is acrylic board therein.
Among embodiment, described lamp door is the aluminium lamp door therein.
Above-mentioned LED coloured plate lamp, a plurality of red LED chips, a plurality of green light LED chip and a plurality of blue-light LED chip can produce ruddiness, green glow and blue light respectively, because ruddiness, green glow and blue light can be combined to form the light of multiple color, therefore adjust the ratio that red LED chip, green light LED chip and blue-light LED chip lighted and just can make LED coloured plate lamp send the light of different colours, thereby satisfy the user to the demand of photochromic environment.

Fig. 1 is the explosive view of the LED coloured plate lamp of an embodiment;
Fig. 2 is the part figure of LED lamp bar among Fig. 1.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
As depicted in figs. 1 and 2, in one embodiment, a kind of LED coloured plate lamp comprises lamp door 110, LGP 120 and LED lamp bar 130.Usually, lamp door 110 is the aluminium lamp door, comprises four deckle board 112a, 112b, 112c, 112d, four deckle board 112a, 112b, 112c, 112d head and the tail adhesion successively.LED lamp bar 130 has 4, is pasted on four deckle board 112a, 112b, 112c, 112d respectively towards a side at lamp door 110 centers.LGP 120 is acrylic board, be installed in the lamp door 110 and the side of LGP 120 over against LED lamp bar 130.LED lamp bar 130 comprises substrate 132, a plurality of red LED chip 134, a plurality of green light LED chip 136 and a plurality of blue-light LED chips 138.Red LED chip 134, green light LED chip 136 are installed on substrate 132 at interval with blue-light LED chip 138.
Above-mentioned LED coloured plate lamp, a plurality of red LED chips 134, a plurality of green light LED chip 136 can produce ruddiness, green glow and blue light respectively with a plurality of blue-light LED chips 138, because ruddiness, green glow and blue light can be combined to form the light of multiple color, therefore adjust red LED chip 134, green light LED chip 136 just can make LED coloured plate lamp send the light of different colours with the ratio that blue-light LED chip 138 is lighted, thereby satisfy the user to the demand of photochromic environment.
In specific embodiment, LED coloured plate lamp also comprises diffuser plate 140, bonnet 150 and reflective membrane (not indicating).Four deckle board 112a, 112b, 112c, 112d respectively have the plate that extends to lamp door 110 centers along 1122.Diffuser plate 140 is carried on the plate of four deckle board 112a, 112b, 112c, 112d along on 1122.LGP 120 is arranged at diffuser plate 140 away from the one side of plate along 1122.Bonnet 150 is installed on lamp door 110 away from the side of plate along 1122.Reflective membrane is arranged at LGP 120 away from the one side of diffuser plate 140.
The above embodiment has only expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
