Abstract
The utility model discloses an LED (light-emitting diode) fluorescent lamp tube structure which is good in safe performance, beneficial to environmental protection and good in heat dissipation effect. The LED fluorescent lamp tube structure comprises a glass lamp tube and an LED lamp bar arranged in the lamp tube, wherein a layer of diffusion film is bonded on the inner wall of the lamp tube; the diffusion film axially extends and forms an open ring structure with a notch in the circumferential direction of the inner wall of the lamp tube; the LED lamp bar is arranged at a position back to the notch. The LED fluorescent lamp tube structure disclosed by the utility model is of a structure formed by uniformly bonding the diffusion film with a certain haze and good insulation property on the inner wall of the glass lamp tube, thus electric appliance connecting wires and components in the glass tube are still wrapped in the diffusion film and free from being exposed to the outside after the glass tube is accidentally broken, thus avoiding the occurrences of electric shock accidents of users; meanwhile, due to the diffusion film with a non-closed structure, the heat energy generated by an LED light source can be diffused to the outside of the lamp tube through the glass wall, and if a heat absorption-dissipation layer is coated on the outer wall of the lamp tube, the efficiency of diffusing the heat in the lamp tube to the outside can be greatly increased.
Description
Technical field
The utility model relates to a kind of LED fluorescent lamp, particularly a kind of structure of LED fluorescent tube.
Background technology
The LED fluorescent tube of being made by glass tube, has transparent pipe and the anti-dazzle light pipe with certain mist degree conventionally.
Transparent pipe light loss is little, is widely used in brightness requirement high, to the less demanding place of dazzle, as parking lot, warehouse, passageway, corridor or basement etc.
Anti-dazzle light pipe is that glass tube inwall or outer wall are carried out to atomization light diffusion technique, normally by the modes such as the japanning of glass tube inwall, acid corrosion or frosted hacking are processed to acquisition.(or outer wall puts the pipe of heat shrinkage film class)
The light that anti-dazzle light pipe sends LED light source is the soft four directions that exposes to evenly, and it is applied to office, classroom, hospital or room etc. more.
Above-mentioned glass lamp still more or less has the following disadvantages:
1) after the unexpected fragmentation of glass tube, the electrical equipment line in fluorescent tube or components and parts be exposed to outside, the personnel that very easily cause get an electric shock, and to consumer, bring very large potential safety hazard.
2) anti-dazzle light pipe adds man-hour carrying out atomization light diffusion, and coating used, acid or frosted material can cause environmental pollution, and these materials can have a strong impact on the healthy of operating personnel.
In order to overcome above-mentioned shortcoming, there is in the recent period a kind of LED fluorescent tube of glass system, it is that outer wall at Transparent lamp tube is nested with a diffusion Membrane cover with insulating properties through thermoplastic, after glass tube fragmentation, diffusion Membrane cover wraps electrical equipment line and components and parts in fluorescent tube, makes it can not produce the generation that people's accident is touched in electric leakage.Meanwhile, select the diffusion barrier of anti-dazzle, also exempt and use coating, acid or frosted material to carry out the diffusion of atomization light to fluorescent tube to add man-hour, the harm to operating personnel's health.
However, it still has the following disadvantages:
The diffusion Membrane cover being placed on outside glass lamp tightly encases glass tube, have a strong impact on the effect that heat that in pipe, LED light source produces outwards distributes by glass tube walls, LED lamp pearl power is now larger, the heat of its generation also increases, in the case, dispel the heat not smooth, the life-span of fluorescent tube will be affected greatly, when serious, can cause managing interior power supply or LED lamp pearl burns out, in addition, in use procedure, when user cleans this kind of fluorescent tube, also easily cause the illumination quality that described diffusion Membrane cover scratches, breakage affects LED fluorescent lamp in the future.
Summary of the invention
The technical problems to be solved in the utility model is to provide that a kind of security performance is good, the structure of the LED fluorescent tube of the glass system that is beneficial to environmental protection and good heat dissipation effect.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:
LED fluorescent tube structure of the present utility model, comprise glass lamp and be arranged at the LED lamp bar in this fluorescent tube, at tube inner wall, paste one deck diffusion film, this diffusion film extends vertically and forms and be with open loop structure jaggy on tube inner wall circumferencial direction, and described LED lamp bar is placed in the position back to described breach.
Described diffusion film corresponding central angle on tube inner wall circumferencial direction is 180 degree-300 degree.
Described central angle is 270-300 degree.
Described LED lamp bar sticks on the tube inner wall of described indentation, there by heat conduction adhesive linkage.
Described heat conduction adhesive linkage is the glue-line of silicone based, silicon cave class, esters of acrylic acid, acrylic class or epoxy resin.
Described diffusion film is light diffusion film.
Described diffusion film is PET light diffusion film, PC light diffusion film or LSD light diffusion film.
Compared with prior art, the utility model adopts the diffusion film with certain mist degree and good insulation preformance is evenly pasted on to the structure on glass lamp inwall, even if make glass lamp of the present utility model after unexpected fragmentation, electrical equipment line in it and components and parts wrap in described diffusion film and outside can not being exposed to, thereby have just avoided the generation of user's electric shock accidents; Simultaneously, diffusion film of the present utility model is non-enclosed construction in fluorescent tube inner periphery direction, and the interior LED light source of fluorescent tube is arranged at the indentation, there of this non-enclosed construction, making heat energy that this LED light source the produces glass wall by indentation, there reach whole glass tube distributes then outside fluorescent tube, if apply the heat radiator composite bed of the reflective heat absorption of one deck internal layer, outer heat radiation on the tube outer wall corresponding with this breach, will greatly improve the efficiency that in fluorescent tube, heat outwards distributes.
