Abstract
The invention discloses a wide-angle light-emitting LED lamp tube. The wide-angle light-emitting LED lamp tube comprises a round tube diffusing lamp shade and lamp holders arranged at the two ends of the round tube diffusing lamp shade, wherein an active radiating substrate is arranged at a position below 1/3 of the diameter of an inner circle of a cross section of the round tube diffusing lamp shade; an LED is arranged on the active radiating substrate; power driving components are arranged between the lamp holders and the active radiating substrate; the active radiating substrate comprises a conductive substrate; a radiating layer or radiating layers is/are arranged on one or two surfaces of the conductive substrate; the radiating layer is made of a nanomaterial; and the nanomaterial comprises at least one of nanocarbon, nano aluminium nitride, nano silicon oxide and nano aluminium oxide. After the LED emits light, the range of the projection area on the other side of the diffusing lamp shade is increased, thereby achieving wide-angle light emission of the LED lamp tube, with the light-emitting angle of about 180-340 degrees.
Description
Technical field
The present invention relates to a kind of lighting, the emitting led fluorescent tube of especially a kind of wide-angle.
Background technology
Existing most of LED fluorescent tube is on structural design, in order to consider the space of substrate and radiator, perhaps add the placement space of power drives, so the position of LED is distributed near the horizontal plane in fluorescent tube center usually, because the lighting angle of most of LED lamp pearl is confined to about 120 degree, though utilize the diffusion lampshade to amplify light-emitting area, but because LED is near the fluorescent tube center, so also can only allow the LED fluorescent tube present the luminance of semi circular surface (about about 180 degree), then can produce than dark areas at the fluorescent tube back side.Therefore, need make improvements.
Summary of the invention
In order to solve the above problems, the object of the present invention is to provide that a kind of simple in structure, weight is light, the wider emitting led fluorescent tube of wide-angle of lighting angle of LED fluorescent tube.
The present invention solves the technical scheme that its problem adopts: the emitting led fluorescent tube of a kind of wide-angle, comprise pipe diffusion lampshade and be arranged on the lamp holder that pipe spreads the lampshade two ends, the position of circular diameter below 1/3rd is provided with active heat-radiating substrate in the cross section of pipe diffusion lampshade, active heat-radiating substrate is provided with LED, is provided with the power drives parts between lamp holder and active heat-radiating substrate.
Described active heat-radiating substrate comprises electrically-conductive backing plate, one side or two sides at described electrically-conductive backing plate are provided with the heat loss through radiation layer, described heat loss through radiation layer is made up of nano material, and described nano material comprises at least a in nano-sized carbon, nano aluminum nitride, nano silicon oxide, the nano aluminium oxide.
Technique scheme can have following improvement project.
The position of circular diameter below 1/3rd is provided with the active heat-radiating substrate of a slice in the cross section of pipe diffusion lampshade.
Position one-tenth the fall V word shape of circular diameter below 1/3rd put and is provided with two active heat-radiating substrates in the cross section of pipe diffusion lampshade.
Described power drives parts substitute with integrated circuit, directly are integrated on the active heat-radiating substrate.
The invention has the beneficial effects as follows: the design adopts active heat-radiating substrate, the substrate and the radiator that replace original LED fluorescent tube, with substrate covers in the tubulose lampshade, utilize the heat loss through radiation mode directly to solve the LED heat dissipation problem at substrate on the one hand, dwindle substrate area on the other hand simultaneously, with the substrate position sedimentation and be fixed near the side in the lampshade, the position of circular diameter below 1/3rd in about pipe cross section, because being incident upon the areal extent of diffusion lampshade opposite side after LED is luminous increases, the wide-angle that reaches the LED fluorescent tube by this is luminous, can reach approximately〉180 degree are to the lighting angle between＜340 degree.The design does not need to use the metal heat sink of traditional LED fluorescent tube, except saving raw material, outside can reducing production costs, more can alleviate the weight of fluorescent tube integral body, and active heat-radiating substrate is based on the conventional substrate improvement and processes, and does not need special processing procedure or equipment just can realize producing in batches fully.Simultaneously, the design's active heat-radiating substrate is coated in the tubulose lampshade of plastics or glass material fully, can avoid exposing potential safety hazards such as the short circuit that exists or electric shock because of the metal part branch.The present invention is simple in structure, and is reasonable in design.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is the structural representation of the cross section of monolithic substrate of the present invention.
Fig. 2 is the structural representation of the cross section of biplate substrate of the present invention.
Fig. 3 is the STRUCTURE DECOMPOSITION schematic diagram of monolithic substrate of the present invention.
The specific embodiment
With reference to Fig. 1, Fig. 2, Fig. 3, the emitting led fluorescent tube of a kind of wide-angle of the present invention, comprise pipe diffusion lampshade 1 and be arranged on the lamp holder 2 that pipe spreads lampshade 1 two ends, the position of circular diameter below 1/3rd is provided with active heat-radiating substrate 3 in the cross section of pipe diffusion lampshade 1, namely as Fig. 1, active heat-radiating substrate 3 shown in Fig. 2 spreads maximum distance L round in the cross section of lampshade 1 less than 1/3rd of diameter of a circle D in the cross section of pipe diffusion lampshade 1 to pipe, active heat-radiating substrate 3 is provided with LED4, is provided with power drives parts 5 between lamp holder 2 and active heat-radiating substrate 3.Described active heat-radiating substrate 3 comprises electrically-conductive backing plate, one side or two sides at described electrically-conductive backing plate are provided with the heat loss through radiation layer, described heat loss through radiation layer is made up of nano material, and described nano material comprises at least a in nano-sized carbon, nano aluminum nitride, nano silicon oxide, the nano aluminium oxide.
Technique scheme can have following improvement project.The position of circular diameter below 1/3rd is provided with the active heat-radiating substrate 3 of a slice in the cross section of pipe diffusion lampshade 1.Position one-tenth the fall V word shape of circular diameter below 1/3rd put and is provided with two active heat-radiating substrates 3 in the cross section of pipe diffusion lampshade 1.Described power drives parts 5 substitute with integrated circuit, directly are integrated on the active heat-radiating substrate 3.
Know-why of the present invention is to adopt active heat-radiating substrate, the substrate and the radiator that replace original LED fluorescent tube, dwindle substrate area simultaneously and utilize the heat loss through radiation mode to solve the LED heat dissipation problem, in addition, substrate placed with the monolithic plane or two put into the word of falling V shape, fix and be coated on fully in the tubulose lampshade of plastics or glass material, substrate position is near the side in the lampshade, the position of circular diameter below 1/3rd in about pipe cross section, because being incident upon the areal extent of diffusion lampshade opposite side after LED is luminous increases, the wide-angle that reaches the LED fluorescent tube by this is luminous, can reach approximately〉180 degree are to the lighting angle between＜340 degree.
