Abstract
The utility model relates to an LED lamp, in particular to an LED panel lamp with a novel plane light source. The LED panel lamp with the novel plane light source mainly solves the technical problems of the prior art that a light guiding plate and a printed light guiding plate are needed when the lateral area light source is used; as the light guiding plate of the large-area plane light source is over-large, the uniformity is over-low; the light guiding plate has larger volume and is thick, thus enabling the whole plane light source to be heavy; LEDs are locked on aluminum material, thus causing non-uniform radiation; the PCB needs to be made of highly heat-conducting material, thus enabling the cost to be high; by using over-optical material, the light source can be seen clearly or a transparent line appears, thus causing the phenomena of 'firefly' and the like. The LED panel lamp with the novel plane light source comprises a rear shell, a metal board is arranged in the rear shell; LED bulbs are distributed on the metal board; each LED bulb is provided with a lens; and a front cover, a diffusion plate and a glass panel are arranged above the LED bulbs in sequence and are all fixed on a frame of the rear shell.
Description
Technical field
The utility model relates to a kind of LED lamp, especially relates to a kind of LED panel light with novel area source.
Background technology
Along with deepening continuously of environmental protection theory, the LED panel light is popular in recent years a kind of novel illumination light fixture.Product is used SMD LED as light source, and the LGP and the diffuser plate that design by precision optics evenly spread light; Than traditional fluorescent tube, soft, the flicker free of its light, and energy-conserving and environment-protective are the optimal selections that replace grid lamp disc.Product is widely used in hotel, market, hospital, contour shunting yard institute of office, convenient and flexible installation.Chinese patent discloses a kind of novel side light type LED back light source apparatus (Granted publication number: CN 201425684Y), it comprises led array and drive circuit and liquid crystal panel, the led array of this side light type LED back light source apparatus be positioned at liquid crystal panel on, down, a left side, the side of right four direction, the distribution of the led array of side light type LED back light source apparatus is non-homogeneous distribution, the light decay curve relation of being inversely proportional to of the LGP that the distribution density of the led array of side light type LED back light source apparatus and this device adopt, being distributed on the liquid crystal panel four direction of the led array of side light type LED back light source apparatus is non-homogeneous arranging all, perhaps being distributed on the liquid crystal panel four direction of the led array of side light type LED back light source apparatus is that part adopts non-homogeneous arranging, and perhaps the led array of side light type LED back light source apparatus is distributed in all to adopt on the liquid crystal panel four direction and evenly arranges.But this side entering type area source need use LGP and printing LGP, large-area area source causes the uniformity too low because LGP is too big, and the LGP volume ratio is bigger, moreover it is thicker, make area source integral body too heavy, LED locks on 4 same aluminium section bars, and it is inhomogeneous to dispel the heat, PCB needs highly heat-conductive material, the cost height is crossed optical material and can be seen light source clearly or a good line occur, causes the generation of firefly phenomenon.
The utility model content
The utility model provides a kind of LED panel light with novel area source, it mainly is to solve existing in prior technology side entering type area source need use LGP and printing LGP, large-area area source is because LGP is too big, cause the uniformity too low, the LGP volume ratio is bigger, moreover it is thicker, make area source integral body too heavy, LED locks on 4 same aluminium section bars, it is inhomogeneous to dispel the heat, and PCB needs highly heat-conductive material, the cost height, cross optical material and can see light source clearly or a good line occur, cause the technical problem of the generation etc. of firefly phenomenon.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
LED panel light with novel area source of the present utility model, comprise back cover, be provided with metallic plate in the back cover, be placed with LED lamp pearl on the described metallic plate, LED lamp pearl is provided with lens, the top of LED lamp pearl is provided with protecgulum, diffuser plate, face glass successively, and protecgulum, diffuser plate, face glass all are fixed on the framework of back cover.Metallic plate can be an aluminium sheet, and all LED lamp pearls can link together and connect power supply by circuit.The printed circuit board (PCB) that LED lamp pearl is installed only needs the printed circuit board (PCB) of the common material of FR-4 to get final product, and does not need highly heat-conductive material.The application of lens can reduce light mixing distance, and the uniformity of optics is provided simultaneously.LGP is used in the utility model cancellation, convenient fixing, and the heat radiation uniformity is relatively good.LED lamp pearl and lens can be arranged into an array.
As preferably, described diffuser plate is provided with printing net-point.On uppermost diffuser plate, increase printing net-point, the uniformity of optics is brought up to more than 90%.Utilize the characteristic of lens and printing net-point on diffuser plate, light mixing distance is reduced, simultaneously can be the weight saving of area source, the uniformity provides, original potential safety hazard owing to too heavily existence is got rid of, can save some installation parts of stationary plane light source simultaneously, install more convenient like this.
As preferably, 4 sides of described back cover inside all are provided with intilted inclined-plane, the light guiding can be thrown and loose to diffuser plate.
Therefore, the utlity model has the optics uniformity and improve, characteristics such as overall weight reduces, and it is more even to dispel the heat, and PCB does not need highly heat-conductive material, reduces cost, and does not have the firefly phenomenon, and is simple and reasonable for structure.
