Abstract

The utility model discloses a reflecting light-emitting diode tube, which mainly comprises a tube body, a heat sink and a luminous module. The reflecting light-emitting diode tube is characterized in that a reflecting layer is formed on the circumferential surface of the tube body and directly corresponds to a light source generated by the luminous module, so that the light source can be directly reflected by the reflecting layer in the tube body, and a soft reflecting indirect light source is generated; moreover, after the heat sink and the tube body are assembled, a radiating part of the heat sink is exposed out of the tube body, so that heat energy generated in the tube body can be quickly transferred out of the tube body through the radiating part, and a good radiating effect is achieved.

Description

Reflection type light-emitting diode fluorescent tube

Technical field

A kind of reflection type light-emitting diode fluorescent tube, is applied on lighting apparatus, and espespecially a kind of light source that a light emitting module in body is produced of the utility model irradiates behind reflecting layer, produces the reflection type light-emitting diode fluorescent tube of a reflective indirect light source.

Background technology

Light emitting diode is widely used in illumination, the made lighting device kind of light emitting diode is various, and have on the market at present the light-emitting diode lamp tube that replaces general fluorescent tube, but, because existing light source directivity and cross by force, easily produce dazzle, light emitting diode make eye cause the problems such as uncomfortable, therefore, the light that light-emitting diode lamp tube produces conventionally must be at least after primary event, the sense of discomfort just can reduce human eye and watch time, refer to Fig. 1, it shown in figure, is existing LED lamp, as the LED lamp 10 in figure, it is mainly provided with a reflection shield 102 in lampshade 101 inner edge groups, at least two light-emitting diode lamp tubes 103 are relatively arranged on reflection shield 102 belows, each light-emitting diode lamp tube 103 is conducted rear a produced light, can be subject to corresponding reflection shield 102 reflects, the light that makes to be reflected can be human eye and accepts, only, each group light-emitting diode lamp tube 103 one group of reflection shield 102 of all must arranging in pairs or groups uses, be with, reflection shield 102 belongs to necessary element in the making of LED lamp 10, referring again to Fig. 2, it shown in figure, is the enforcement schematic diagram of existing light-emitting diode lamp tube, as figure, existing light-emitting diode lamp tube 103 upper limbs, have corresponding with reflection shield 102 and be an exiting surface 1031 of transparence, interior group of light-emitting diode lamp tube 103 is provided with a circuit substrate 1032, and be arranged at exiting surface 1031 belows, again, light-emitting diode lamp tube 103 lower edge groups are provided with the heat-radiating substrate 1033 using as heat radiation, but, because heat-radiating substrate 1033 is made (being generally aluminium) with metal material, therefore heat-radiating substrate 1033 cannot printing opacity, when the light of light emitting diode is after reflection shield 102 reflections, part light can reflex on the heat-radiating substrate 1033 of light-emitting diode lamp tube 103, and then part light is blocked, cause light-emitting diode lamp tube 103 belows to form a shade block, when illumination, can cause the inconsistent problem of luminous intensity, moreover it is coated completely that aforesaid heat-radiating substrate 1033 is subject to light-emitting diode lamp tube, be that the actual radiating effect of light-emitting diode lamp tube 103 made is not good.

Utility model content

Because above-mentioned problem, the utility model is according to the experience of being engaged in for many years relevant industries and light-emitting diode lamp tube design, study and improve for light-emitting diode lamp tube and light ray reflection structure thereof, the phase can be designed the entity products that can address the above problem; Edge this, main purpose of the present utility model is to provide a kind of can directly produce reflective indirect light source and the good reflection type light-emitting diode fluorescent tube of radiating effect.

For reaching above-mentioned purpose, reflection type light-emitting diode fluorescent tube of the present utility model, it is mainly provided with a reflecting layer towards fluorescent tube center in periphery formation or the group of a body, and complete mutual group with a radiating seat and body and establish, again, radiating seat upper set is provided with a light emitting module that is laid with the circuit substrate of at least two light emitting diodes, the reflex forming by described reflecting layer, the light that can make light emitting diode launch is reflected after layer reflection, further be dissipated into outside fluorescent tube, to form a reflective indirect light source, and then make the light shining out form soft light source, moreover, radiating seat and body complete mutual group establish after, one radiating part of radiating seat is exposed to outside body, the heat energy being produced while moving with light emitting diode, can be conducted to fast outside body by radiating seat, make entirety can produce excellent radiating effect.

Preferably, the light that this light-emitting diodes body diode is launched after current lead-through, is to be subject to after this reflective layer reflects, forms a reflective indirect light source.

Preferably, this relative group of portion of establishing of this radiating seat is a chute, after can slipping into for this group portion of establishing of this body, completes relative group and establishes.
