Abstract
An LED tube comprises a shell, a substrate, a plurality of LED light sources, a reflecting part and an adhering part. The substrate and the LED light sources are disposed in the shell. The LED light sources are disposed on the substrate. The reflecting part is fixed relative to the substrate. The adhering part is used for adhering the substrate to the inner wall of the shell. At least one of the lateral edges of the reflecting part is abutted against the inner wall of the shell. Each lateral edge, abutted against the shell, of the reflecting part is used for reflecting part of the light emitted by the LED light sources towards the inner wall of the shell. The LED tube has the advantage that light spot generation can be avoided.
Description
Technical field
The utility model relates to lighting field, particularly a kind of LED fluorescent tube.
Background technology
In recent years, based on features such as environmental protection, energy-conservation, high color rendering index (CRI)s, LED fluorescent tube is widely applied to the occasions such as house, office.For example, Granted publication day is on May 15th, 2013, the patent No. is that 201220591654.2 Chinese utility model patent has disclosed a kind of LED fluorescent tube, this LED fluorescent tube comprises tube housing, LED lamp plate, power supply and plug, the two ends of tube housing are equipped with plug, LED lamp plate and power supply are all arranged on the inside of tube housing, and power supply is connected with lamp plate by binding post.
Because these LED light sources of distance from bottom of this tube housing are nearer, when LED light source is luminous, can produce hot spot in the bottom of this tube housing.
Utility model content
In view of this, be necessary to provide a kind of LED fluorescent tube that can not produce hot spot.
A kind of LED fluorescent tube, comprise shell and be arranged on substrate and the multiple LED light source in this shell, described LED light source is arranged on this substrate, also comprise reflecting component and stickers, this reflecting component relatively this substrate is fixed, this stickers for by this substrate sticking to this inner wall of tube shell, at least one side of this reflecting component and the inwall butt of this shell, the side of this reflecting component and this shell butt is used for part light that described LED light source is sent and reflects towards this inner wall of tube shell.
Compared with prior art, this LED fluorescent tube by arranging reflecting component in shell, and the substrate that is provided with LED light source is arranged on and is pasted on this inner wall of tube shell with stickers, because this reflecting component is made up of trnaslucent materials, the part light that LED light source sends is reflected towards fluorescent tube top, improve light extraction efficiency; Another part light shines to the sidewall of this fluorescent tube bottom through refraction.Because this reflecting component can be controlled the luminous flux penetrating from this tube shell bottom, so can solve tube shell bottom hot spot problem, reduce the light loss that light causes in conductive process, improve the light efficiency of light source.This LED fluorescent tube is had advantages of and can not produce hot spot.

Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the utility model is described in further detail.
Fig. 1 is the LED fluorescent tube 100 overall structure decomposing schematic representations of the utility model the first embodiment, and this LED fluorescent tube 100 comprises that shell 10, reflecting component 20, substrate 30, multiple LED light source 40 and stickers 50(are as shown in Figure 4).This substrate 30 is list structure, and these LED light sources 40 are arranged in parallel within the middle part of this substrate 30.This shell 10 is made up of glass material, and these shell 10 inwalls are coated with and are covered with diffusion material, make described LED light source 40 bright dippings more even.Relative this substrate 30 of this reflecting component 20 is fixing, at least one side of this reflecting component 20 and the inwall butt of this shell 10, this reflecting component 20 is made up of transparent or semitransparent material, and this reflecting component 20 reflects towards these shell 10 inwalls for the part light that described LED light source 40 is sent with the side of these shell 10 butts.Whether the transparency of this reflecting component 20 and refractive index basis can form hot spot is selected.
Please refer to Fig. 3 and Fig. 4, this reflecting component 20 is made up of the plastic sheeting with some strength, and this reflecting component 20 is strip structure, and the middle part of this reflecting component 20 is fixed on the bottom of this substrate 30, can adopt bonding method to realize fixing.One side of this stickers 50 and the middle part of this reflecting component 20 are bonding, and the inwall of the opposite side of this stickers 50 and this shell 10 is bonding, and this stickers 50 is made up of highly heat-conductive material.The width of this reflecting component 20 is greater than the width of this substrate 30, and when assembling, two relative sides of this reflecting component 20 are all connected to the inwall of this shell 10 by symmetrical bending.
When work, the light part that described LED light source 40 sends is transmitted to the lower half of shell 10 by reflecting component 20, and another part is the upper half reflection towards these shell 10 inwalls by this reflecting component 20, makes the whole fluorescent tube can uniformly light-emitting.And the heat that described LED light source 40 produces can be delivered to reflecting component 20 from substrate 30, then be delivered to the inwall of shell 10 from reflecting component 20, thereby outwards distribute from this shell 10.Because this shell 10 is made up of glass material, therefore this LED fluorescent tube 100 has good radiating effect.The moulding of considering glass lamp is pipe, and therefore this LED fluorescent tube 100 adopts stickers 50 reflecting component 20 to be fixed on to the inwall of this shell 10.The part light that these LED light sources 40 can be sent due to this reflecting component 20 reflexes to the top of this shell 10, therefore can improve the light extraction efficiency of this LED fluorescent tube 100.From the angle analysis of light source utilization ratio, it is mainly that send at top from tube housing that the having of fluorescent lamp used up, and the light that tube housing sends near the bottom of substrate is mainly to set off environment by contrast, can not play the effect of illumination.Along with the raising of these LED fluorescent tube 100 light extraction efficiencies, can reduce the usage quantity of described LED light source 40, thereby effectively reduce costs.
In sum, this LED fluorescent tube 100 is by the interior reflecting component 20 that arranges of shell 10, the substrate 30 that is provided with LED light source 40 is arranged on to the middle part of reflecting component 20, make two relative sides of this reflecting component 20 be all connected to the inwall of this shell 10 by symmetrical bending, thereby the part light that LED light source 40 sends reflects towards these shell 10 inwalls by this reflecting component 20, solve inhomogeneous the caused hot spot problem of light source luminescent, reduce the light loss that light causes in conductive process, improved the light efficiency of light source.Because this shell 10 is made up of glass material, therefore this LED fluorescent tube 100 has good radiating effect.
The fixed form of this reflecting component 20 and this substrate 30 has multiple, is not limited to bonding method.For example, can some perforates be set at the middle part of this reflecting component 20, this stickers 50 is pasted through this perforate and this substrate 30, realize the fixing of these reflecting component 20 relative these substrates 30.
These are only preferred embodiment of the present utility model above, not in order to limit the utility model, any those skilled in the art, not departing from this programme technical scope, can work as and utilize the technology contents of above-mentioned exposure to make the equivalent embodiment that a little change is equal variation.In every case for departing from technical solutions of the utility model content, according to the utility model technical spirit to any amendment made for any of the above embodiments, be equal to replacements, improvement etc., within all should being included in the scope that the utility model protects.
