Accompanying drawing explanation
Fig. 1 is the assembling schematic diagram of the utility model LED flat lamp.
In figure: 1: lamp door; 2: diffuser plate; 3: light-shielding sheet; 4: light guide plate; 5: reflectance coating; 6: lamp bar; 7: smallpox glue; 8: backboard.
Detailed description of the invention
For making the object of the utility model embodiment, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the utility model embodiment, technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, the every other embodiment that those of ordinary skill in the art obtain under the prerequisite not making creative work, all belongs to the scope of the utility model protection.
As shown in Figure 1, a kind of LED flat lamp that the utility model embodiment provides, comprises backboard 8 and lamp door 1, and the material of backboard 8 and lamp door 1 is aluminium alloy, has good physical characteristic.
Backboard 8 is the hollow rectangular box body without upper bottom surface, backboard 8 inside is cascading reflectance coating 5, light guide plate 4 and the diffuser plate 2 identical with backboard 8 bottom surface shape from the bottom to top, light guide plate 4 and diffuser plate 2 adopt nanocomposite optical technology, light guide plate 4 is a palm of acrylic, and its light transmittance is good.Wherein, the upper bottom surface of backboard 8 and bottom surface are be described for the direction of Fig. 1 dorsulum 8.
Be provided with lamp bar 6 between light guide plate 4 and backboard 8 sidewall, the quantity of lamp bar 6 is two or four, and lamp bar 6 is fixed on backboard 8 sidewall, and lamp bar 6 is LED lamp bar, can not produce infrared ray or ultraviolet, and its light source is the light source of energy-saving and environment friendly.The electricity conversion of LED lamp bar is high, generates heat little, and the electric energy conversion of 90% is visible ray, and the electric energy conversion of ordinary incandescent lamp 80% is heat energy, only has 20% electric energy conversion to be luminous energy; Within 1000 hours, only consume several years electricity, and common 60W incandescent lamp 17 hours consumptions 1 degree of electricity, common 10W electricity-saving lamp 100 hours consumptions 1 degree of electricity, therefore uses LED lamp bar more energy-efficient.
Also be provided with the light-shielding sheet 3 mated with lamp bar 6 between light guide plate 4 and backboard 8 sidewall, light-shielding sheet 3 is fixed on light guide plate 4; Lamp door 1 to be sleeved on above diffuser plate 2 and to be fixedly connected with backboard 8.
The light that lamp bar 6 sends enters light guide plate 4 from the sidewall of light guide plate 4, reflection ray is produced by reflective membrane 5, when reflection ray is mapped to the sidewall being blocked the light guide plate 4 that paper 3 blocks, can time it spreads, and destroy conditioned reflex, light is penetrated from the front of light guide plate 4, ensures light transmittance and light guide effect, improve the utilization rate of light.
When LED flat lamp is less, the quantity of lamp bar 6 is two, lamp bar 6 is symmetricly set in the both sides of light guide plate 4, wherein, be symmetrical arranged and refer to lamp bar 6 is symmetricly set in light guide plate 4 both sides with the longitudinal centre line of light guide plate 4 or cross central line, and be arranged between light guide plate 4 and backboard 8 sidewall, then lamp bar 6 is fixed on the sidewall of backboard 8, and the width of lamp bar 6 is identical with the height of light guide plate 4 sidewall, and light-shielding sheet 3 is covered on light guide plate 4 sidewall of other both sides completely.
When LED flat lamp is larger, the quantity of lamp bar 6 is four, lamp bar 6 is arranged along the surrounding of light guide plate 4 respectively, lamp bar 6 is arranged between the surrounding sidewall of light guide plate 4 and backboard 8 sidewall, and is fixed on backboard 8 sidewall, and the width of lamp bar 6 is less than the height of light guide plate 4 sidewall, therefore, lamp bar 6 cannot cover light guide plate 4 sidewall completely, and make light guide plate 4 sidewall expose the outer part of lamp bar 6, light-shielding sheet 3 is covered in light guide plate 4 sidewall completely and exposes in the part of lamp bar 6.
The reflectance coating 5 between lamp door 1 with backboard 8, light guide plate 4 and diffuser plate 2 act on owing to can be under pressure after lamp door 1 is fixedly connected with backboard 8, therefore also substrate is provided with between reflectance coating 5 and backboard 8, the material of substrate is foam, because foam has elasticity, the effect preventing from extruding and cushioning therefore can be played.
For fixing base better, by smallpox glue 7, substrate is fixed on backboard 8.
Backboard 8 is also provided with the through hole for interspersed electric wire.
Last it is noted that above embodiment is only in order to illustrate the technical solution of the utility model, be not intended to limit; Although be described in detail the utility model with reference to previous embodiment, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of each embodiment technical scheme of the utility model.
