Abstract
The utility model relates to an LED fluorescent lamp, comprising a lamp body and LED luminous bodies, which is characterized in that two ends of the lamp body are respectively provided with a reflective cup; the reflective surfaces of the reflective cups are oppositely arranged; the bottom center of the reflective cup is provided with an LED luminous body; the outgoing faces of the two LED luminous bodies are oppositely arranged; a high gloss light guide plate is provided in the lamp body between the two LED luminous bodies; the upper end face of the high gloss light guide plate is provided with a reflective plate and the lower end face is provided with a high transparency high haze diffusion plate. The LED fluorescent lamp can emit uniform and soft light without glaring, has low production cost and has high heat dissipation performance.
Description
One, technical field
The utility model relates to a kind of LED fluorescent lamp, relates in particular to a kind of LED fluorescent lamp to utilize high luminance light guide board to make.
Two, background technology
LED is described as the green illumination product of 21 century, compares with conventional light source, and incomparable advantage such as high-purity, life-span length, environmental protection and energy saving are arranged, and nowadays almost global sight all focuses on this novel light source.As the disclosed LED fluorescent lamp of Chinese utility model patent document CN1908989Y, its LED illuminator is for to arrange along the body axial direction, light source is a straight-down negative, the LED illuminator go out light center towards exiting surface, owing to be subjected to the restriction of its LED illuminator self lighting angle, often cause the LED illuminator very bright on every side, can't make ejaculation light evenly soft, make the light of ejaculation have dazzle, do not meet people's vision requirement; The required LED quantity of this LED fluorescent lamp is many on the other hand, causes the manufacturing cost height.
Three, summary of the invention
At above-mentioned shortcoming, the purpose of this utility model be to provide a kind of adopt the sidelight source and by LGP adjust that radiation direction makes the light of ejaculation evenly soft, not dazzle and the low LED fluorescent lamp of production cost.
The utility model technology contents is, a kind of LED fluorescent lamp comprises lamp tube body and LED illuminator, it is characterized in that at fluorescent tube body two ends one reflector being set respectively, and the reflective surface of reflector is provided with in opposite directions; Bottom centre at reflector is provided with a LED illuminator, and the exiting surface of two LED illuminators is provided with in opposite directions; Be provided with a high luminance light guide board in the lamp tube body between two LED illuminators, be provided with a reflecting plate in the upper surface of high luminance light guide board, the printing reflection site, upper surface or the engraving site of high luminance light guide board are provided with the high mist degree diffuser plate of a high transmission rate in the lower surface of high luminance light guide board.
In the utility model, high luminance light guide board adopts optical grade PMMA material and precision extrusion molding, mode in the bottom surface of LGP with screen painting stamps pip, the LED lamp is positioned at the LGP side, the light utilization reflection that led light source sent is to end conduction, and when light was run into pip, reverberation can be toward all angles diffusion, destroy the diffuse reflection that total reflection condition changes light into then, penetrate by LGP is positive again.Utilize various densitys, diffusion point not of uniform size, can make the LGP uniformly light-emitting.
In the utility model, the high mist degree diffuser plate of high transmission rate diffuser plate adopts optical grade PMMA material and precision extrusion molding, and in diffuser plate, diffusant evenly distributes, and is added with special materials such as ultraviolet absorber, antistatic additive simultaneously.When the light process has the material of different refractivity, can produce refraction and reflex, reach the diffusion effect of light.
In above-mentioned LED fluorescent lamp, the LED illuminator is through an encapsulated LED bulb.
For improving the heat dispersion of LED fluorescent lamp, the LED illuminator links to each other with printed circuit, the insulating barrier in aluminium base front links to each other with printed circuit, the aluminium base reverse side is connected with the heat-conducting block firmware, aluminium base contacts by coating heat-conducting glue formation face with heat-conducting block, simultaneously heat-conducting block is connected with radiating piece with the air contact, and radiating piece is connected with lamp tube body.Aluminium base, heat-conducting block, radiating piece and body shell organically in conjunction with forming good cooling system, efficiently solve the heat dissipation problem of high-powered LED lamp.
The advantage that the utility model is compared with prior art had is: the light of ejaculation is evenly soft, the LED fluorescent lamp of not dazzle, meets people's vision requirement; Production cost is low, and heat dispersion might as well simultaneously.
Four, description of drawings
