Description
Technical field
The utility model relates to a kind of lighting device, is specifically related to LED lamp tube.
Background technology
LED lamp tube is a kind of illuminating product for replacing conventional fluorescent, and its life-span is high, does not need the parts such as ballast, starter, good illumination effect, obtains applying more and more widely.
Current existing LED lamp tube is all that the mode that employing coats fluorescence coating at tube inner wall guarantees that the light that fluorescent tube sends is soft.This coating structure, except inadequate environmental protection, also exists and produces trouble, inefficient defect.In addition, along with the increase of service time, easily there is the phenomenon of turning to be yellow in fluorescence coating, affects illumination effect.When LED lamp tube damage is scrapped, because tube inner wall scribbles coating, therefore it no longer can reclaim, and easily produces environment and pollutes.
Summary of the invention
In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide that a kind of illumination effect is good, structure is simple, painting formula of the exempting from Novel LED lamp tube of easy to assembly, environmental protection.
The utility model solves the technical scheme that its technical problem adopts:
One exempts from painting formula Novel LED lamp tube, comprise glass tube and be located at the circuit lath of glass tube inner chamber along glass tube axial direction, circuit lath is fixed on the inwall of glass tube, circuit lath is distributed with LED lamp bead, also comprise the PC diffusion sheet cylinder that the cross section of mating with described glass tube cavity shape is curved, described PC diffusion sheet cylinder to be flush-mounted in glass tube and to fit with the inwall of glass tube, and the both sides of PC diffusion sheet cylinder are connected to the both sides of circuit lath.
As preferred embodiment, described circuit lath is aluminium base or heat-conductive glass-fiber plate.
As preferred embodiment, between described circuit lath and the inwall of glass tube, be provided with one deck thermal conductive silicon glue-line.
The beneficial effects of the utility model are: the utility model adopts PC diffusion sheet cylinder to replace the coating structure of tradition setting, can ensure good illumination effect after arranging PC diffusion sheet cylinder; This to exempt from painting formula LED lamp tube convenient for production, can complete assembling, do not need additionally to be fixed, efficient productivity by the mode inserted; Glass tube inwall does not have coating, can reclaim easily, economize energy, environmental protection.
Accompanying drawing explanation
Be further detailed below in conjunction with the drawings and specific embodiments:
Fig. 1 is perspective view of the present utility model;
Fig. 2 be in Fig. 1 A-A to cross-sectional structure schematic diagram.
Symbol description: 1-glass tube, 2-lamp holder, 3-LED lamp pearl, 4-circuit lath, 5-thermal conductive silicon glue-line, 6-PC diffusion sheet cylinder.
Detailed description of the invention
Fig. 1 is the structural representation of LED lamp tube, its global shape and conventional fluorescent similar, form primarily of the glass tube 1 be arranged in and the lamp holder 2 that is arranged in glass tube 1 both sides.As conventional fluorescent is different, the illumination mode that LED lamp tube adopts arranges LED lamp bead 3 in whole piece glass tube 1.During work, all LED lamp bead 3 are luminous, form the effect of Integral luminous.
Concrete structure is with reference to Fig. 2.LED lamp bead 3 is distributed on a circuit lath 4.This circuit lath 4 is elongated linear plates, and its axial direction along glass tube 1 is arranged, mainly plays the effect providing operating current to LED lamp bead 3.In various embodiments, this circuit lath 4 can adopt different materials to make, such as, can be aluminium base, or heat-conductive glass-fiber plate etc., selected material require meets the needs that LED lamp bead 3 is dispelled the heat.
As shown in Figure 2, circuit lath 4 is fixed on the inwall of glass tube 1 inner chamber, and as can be seen from the figure, the position that circuit lath 4 distributes only accounts for the sub-fraction position of inwall.Circuit lath 4 can be fixed on inwall in different ways, as long as meet effect that is firm and transferring heat.Preferably, as shown in this embodiment, circuit lath 4 is fitted on the inwall of glass tube 1 by one deck thermal conductive silicon glue-line 5.Thermal conductive silicon glue-line can play the effect of bonding and good transferring heat.
The utility model adopts the mode arranging PC diffusion sheet cylinder 6 in glass tube 1 to realize the illumination effect process of LED lamp tube.Particularly, the global shape of PC diffusion sheet cylinder 6 mates with the cavity shape of glass tube 1, the curved shape in its cross section.When assembling, when circuit lath 4 complete fixing after, directly PC diffusion sheet cylinder 6 is inserted in glass tube 1, now, the both sides of PC diffusion sheet cylinder 6 are connected to the both sides place of circuit lath 4, PC diffusion sheet cylinder 6 is fitted with the inwall of glass tube 1, and PC diffusion sheet cylinder 6 coordinates with both glass tubes 1 inwall of glass tube 1 is filled.PC diffusion sheet cylinder abuts rear PC diffusion sheet cylinder 6 and can closely fit on the inwall of glass tube 1 with circuit lath 4, and can not produce loosening phenomenon, guarantees that position can be firm.
As can be seen from the above description, PC diffusion sheet cylinder 6 does not need to be fixed by other fixed form, and the mode of only mating by size is carried out installation and fixed.This mode is easy to assembly, and structure is simple, can change easily.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
