Description

Direct type frame-free panel lamp

Technical Field

The utility model belongs to the technical field of the illumination lamps and lanterns technique and specifically relates to straight following formula frameless panel lamp.

Background

At present, panel lamps (LED light sources) are more and more common in the market and are used as a high-grade indoor lighting lamp, the outer frame of the panel lamp is usually formed by aluminum alloy through anodic oxidation, the LED panel lamp is unique in design, light forms an even plane lighting effect after passing through a light guide plate with high light transmittance, the illumination uniformity is good, light is soft and comfortable, brightness is not lost, and eye fatigue can be effectively relieved. Therefore, the method is very popular with consumers.

The structure of the panel lamp with the frame on the market is generally that the whole light guide plate is placed in the bottom frame of the lamp with the frame, and then a diffusion plate is inserted into the frame opening of the bottom frame to form the panel lamp structure. This structure has disadvantages in that: because the draw-in groove wall and the diffuser plate of frame are hugged closely, after the light guide plate light-emitting, there is the shadow, there is the black limit phenomenon in diffuser plate and the relative position department of frame in the light that diverges from the diffuser plate.

In order to solve the above problems, some proposed design structures of frameless panel lamps, such as the utility model patent with the publication number of CN205504659U, disclose a frameless panel lamp and a ceiling curtain wall of the panel lamp, please refer to the abstract figures and the specific embodiments thereof, because the first clip arm 51 and the second clip arm 52 are present, so that the first clip arm 51 is in close contact with the diffusion plate 2, so that the light is emitted from the light guide plate 2 and diffused by the diffusion plate 1, and the four sides of the light emitting surface of the panel lamp have shadow parts when viewed from the outside of the panel lamp, which affects the light emitting effect, in addition, as seen from the figure 4 of the utility model, the splicing structure of the frameless panel lamp is a physical splicing structure, which aims to fix the installation modes of a plurality of panel lamps, the splicing gap between each panel lamp is large, the light emitting effect is not considered, the light emitting surface shadow is large, the connecting nut structure between the single panel lamps can obviously not emit light, the segmentation of the light-emitting effect can be caused, and regular shadow parts can exist when the overall visual effect is seen, so that the effect of overall screen shadowless splicing cannot be achieved.

The prior art of the plastic uptake process products in the market generally adopts the traditional process, but the traditional process has chamfers (arc angles or oblique angles are commonly called as R angles), the sizes of the chamfers (the arc angles or the oblique angles) are larger, and the product has overlarge draft. The mask with the chamfer independently has the defects of large product chamfer, large pattern drawing and incapability of forming a square/rectangle with a straight edge and a right angle in the light emitting aspect; and when splicing a plurality of such panel lamps, because every face guard four corners all has the chamfer, then the panel lamp structure concatenation part after the concatenation is not closely laminated, then can have a plurality of tiny no light regions, influences holistic visual effect, can't reach the effect of shadowless concatenation.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a novel panel light structure to there being influence illuminating effect problem that leads to of light loss phenomena such as shadow black border to panel light structure among the prior art.

In order to achieve the above purpose, the utility model adopts the following technical scheme: a direct type frameless panel lamp comprises a rear cover plate, wherein LED light source modules are arranged on the surface of the rear cover plate, a reflector is covered on each LED light source module, two sides of the rear cover plate are connected with lamp boxes, the direct type frameless panel lamp also comprises an integrated face shield playing a role in light diffusion, the integrated face shield is arranged above the rear cover plate, the side edge of the integrated face shield is attached to the outer wall of the lamp boxes and fixedly connected with the lamp boxes, and a ninety-degree angle is formed between the side edge of the integrated face shield and a face shield main body of the integrated face shield; the part of the lamp box facing the inner side face of the mask main body is provided with an inclined plane, and the integrated mask is manufactured by the following processing steps:

the method comprises the following steps: the method comprises the following steps of manufacturing an integrated mask blank by adopting a plastic suction processing process, specifically, heating a flat hard sheet plate made of acrylic or PC material or PS material to soften the plate, absorbing the softened plate on the surface of a mold by adopting vacuum, and forming after cooling; the integrated mask blank is provided with a flat mask main body and a mask side edge, and a chamfer angle is formed between the mask side edge and the mask main body;

step two: and (4) milling, cutting and routing right-angle edges at the four corner edges of the integrated mask blank by a milling and routing machine tool according to preset design requirements to form an integrated mask finished product. The direct type frameless panel lamp is combined with an integrated mask, so that the luminous flux is high, the illumination is increased, the efficiency is high, the consumption is low, the energy is saved, the environment is protected, the energy is saved, the structural design is adopted, the inclined plane can generate a light reflection effect relative to the reflector, and meanwhile, the lamp is fixed.

The panel lamps are spliced into an integral structure. A plurality of panel light splice each other all around and form the comprehensive screen structure of large size, establish outside because of integral type face guard cover, consequently be equivalent to a plurality of integral type face guards splice each other, adopt the utility model discloses an integral type face guard of processing method processing is ninety degrees angles between its face guard main part and the cover side, and furthest has avoided the light cutting phenomenon between the panel light, can form the better whole screen of effect.

Compared with the prior art, the utility model, adopt the utility model discloses the frameless panel lamp of integral type face guard, the light emitting area is even, no dark space, effectual, make the LED panel lamp reach the effect that the LED light emitting area is unshaded, the panel lamp of a plurality of unshaded, can form the super large full-face screen that can splice together, LED panel lamp modularization moreover, can separate the split, the installation is simple, need not to produce fixed connection each other, the cost of transportation is low, can arrange different molding between the panel lamp, realize different lighting demands.
