Abstract
A LED light panel with high light efficiency, compact structure, small volume and stable properties comprises a printing circuit board (3) for assembling LED emitting light tubes. The device is characterized in that the said printing circuit board (3) is provided with a plurality of LED emitting light tubes (1) embedded in the clear resin coating on top and coated with a thermal conduction resin layer (4) with the compound heat radiation plate (5) at the bottom. The utility model is suitable to be made of LED lighting terminal products with large power.
Description
Technical field
The utility model relates to lighting, particularly light-emitting diode (LED) illuminating lamp.
Background technology
Be energy-conservation required at present, all greatly developing LED (Light EmittingDiode-light emitting diode) lighting engineering both at home and abroad, and obtaining certain achievement.This semiconductor light emitting technology of LED is applied to illumination, has become the inexorable trend that substitutes traditional lighting; The similar products at home and abroad technology has at present: 1, utilization great power LED pipe is made the high-power illumination lamp, but have two to cause weakness greatly, first great power LED pipe properties of product, quality instability, it two is that light efficiency is low, best in fact can only accomplish every watt 30 lumen, how much not better than incandescent lamp, energy-conservation hardly; 2, make light fixture with the stable low-power LED pipe of technology maturation; domestic existing how tame; its shortcoming is that volume is big; light efficiency is at the most about every watt 40 lumen, though energy saving is arranged, not remarkable; simultaneously a tool not only protection against the tide but also dustproof protecting sheathing must be set; thereby high-power LED light source can not become an independently end product, as can be for the bulb of the supporting selection of various light fixtures, fluorescent tube etc.
Summary of the invention
The utility model will solve present LED lighting engineering product or quality, unstable properties, light efficiency is low, or complex structure, volume is big, is difficult to form the problem of end product, a kind of LED light plate of the present utility model is provided for this reason, this light plate light efficiency height, compact conformation, volume is little, stable performance can become the high-power LED illumination end product.
For addressing the above problem, the technical solution adopted in the utility model is to be provided with the printed circuit board (PCB) that the LED luminous tube is installed, its special character is that several LED luminous tubes are installed on described printed circuit board (PCB), on described printed circuit board (PCB), be laminated with the transparent resin layer envelope and buried described several LED luminous tubes, below printed circuit board (PCB), be coated with the heat-conducting resin glue-line, be compounded with the heat radiation plate below the heat-conducting resin glue-line.
Described transparent resin layer preferably fusion has the composite transparent resin bed of crystal pearl particulate.The transparent resin layer envelope is buried described LED luminous tube, becomes protective clear layer; The composite transparent resin bed that fusion crystal pearl particulate forms has the printing opacity scattering property, can overcome the little defective of LED pipe beam angle.Described crystal pearl particulate is quartzy fine powder, obtains through ball milling with crystal material.
The blended amount of crystal pearl particulate is advisable with 0.3～0.8% of described compound resin gross weight.
Coated with thermally conductive resin glue-line such as epoxy heat conduction glue-line below the printed circuit board (PCB), it has thermal conductivity and insulating properties, is a compound heat radiation plate such as the aluminium radiating board in outside more in its lower section, plays thermolysis; This is more practical in conjunction with silica gel insulating heat-conductive cloth with the silicone heat-conducting glue than having, effective and technology is simple.
The utility model so the low-power LED luminous tube has been combined to form the great power LED illuminator, has embodied practicality, high light efficiency, feature of long life because several LED luminous tubes are installed on printed circuit board (PCB); Bury described several LED luminous tubes owing to be laminated with the transparent resin layer envelope on the printed circuit board (PCB), so can embody compact conformation, firm, waterproof and dustproof, aging-resistant characteristics; Fusion has the crystal ball particulate to form the composite transparent resin bed in transparent resin, adopts the utility model of this transparent resin layer, can increase the beam angle of LED luminous tube; Again because the utility model is compounded with the heat radiation plate through applying a heat-conducting resin glue-line below printed circuit board (PCB), so good heat dissipation effect.The utility model compact overall structure, firm, volume is little, can become independently led light source end product, select for use for various light fixtures are supporting, it can be made module lamp plates such as 5 watts, 10 watts, 20 watts, 30 watts and select and be combined into various large-power lamps for use for light fixture manufactory.Light efficiency of the present utility model can surpass every watt 60 lumen.Because the directed luminous characteristics of LED, the utility model is applied to road lighting, under power, environment, height the same terms, its illumination improves about 3 times than the most energy-conservation present Metal halogen lamp, sodium vapor lamp, as be made into 120 watts of LED lamp plates with the utility model, can directly substitute 250 watts of Metal halogen lamps, almost identical with 400 watts of Metal halogen lamp effects, embodied powerful power savings advantages.

Fig. 1 is the utility model structural representation.
The concrete real mode of implementing
The LED light plate, has printed circuit board (PCB) 3, several LED luminous tubes 1 are installed on printed circuit board (PCB) 3, on printed circuit board (PCB), be laminated with transparent resin layer 2 envelopes and buried described several LED luminous tubes, fusion has the crystal pearl particulate in the described transparent resin, crystal pearl particulate blended amount be after the fusion total resin weight 0.3%～0.8% in a kind of amount, below printed circuit board (PCB), be coated with heat-conducting resin glue-line 4, be compounded with aluminium radiating board piece 5 below the heat-conducting resin glue-line.
Selected LED luminous tube and quantity thereof constitute 5 watts, 10 watts, 20 watts or 30 watts of light plate modules of the present utility model, various such modules can be combined into the light fixture of different capacity as required, this light plate module as 6 20 watts this light plate modules or 4 30 watts can constitute 120 watts of LED light fixtures, specifically presses lamp housing according to lamp manufacturers and decides.
Claims (1)
1, LED light plate, has the printed circuit board (PCB) (3) that the LED luminous tube is installed, it is characterized in that on described printed circuit board (PCB) (3), being equipped with several LED luminous tubes (1), on described printed circuit board (PCB), be laminated with transparent resin layer (2) envelope and buried described several LED luminous tubes, below printed circuit board (PCB), be coated with heat-conducting resin glue-line (4), be compounded with heat radiation plate (5) below the heat-conducting resin glue-line.
