Abstract
A reflection type light-emitting diode lamp tube mainly comprises a tube body, a radiating seat and a light-emitting module. A reflection layer is formed on the circumference face of the tube body to enable the reflection layer to directly correspond to the light-emitting module to generate a light source. Therefore, the light source can be directly reflected by the reflection layer in the tube body to further generate soft reflection type intermittent light source. After the radiating seat is assembled with the tube body, the radiating portion of the radiating seat is exposed to the outside of the tube body. Therefore, heat energy generated in the tube body can be transferred to the outside of the radiating portion quickly to achieve the good radiating effect.
Description
Technical field
A kind of reflection type light-emitting diode fluorescent tube, be applied on lighting apparatus, the present invention is espespecially a kind of establishes a reflecting layer in a body periphery group, behind the one light source irradiation reflecting layer that the light emitting module in body can be made to produce, the reflection type light-emitting diode fluorescent tube of the indirect light source that generation one is reflective.
Background technology
Light emitting diode is widely used in illumination, lighting device wide variety made by light emitting diode, and have the light-emitting diode lamp tube replacing general fluorescent tube at present on the market, but, eye is made to cause the problems such as uncomfortable because light emitting diode exists excessively strong, the easy generation dazzle of light source directivity, therefore, the light that light-emitting diode lamp tube produces at least after primary event, just must can reduce sense of discomfort during human eye viewing usually, refer to Fig. 1, it is existing LED lamp shown in figure, as the LED lamp 10 in figure, it is mainly provided with a reflection shield 102 in a lampshade 101 inner edge group, at least two light-emitting diode lamp tubes 103 are relatively arranged on below reflection shield 102, each light-emitting diode lamp tube 103 is by conducting rear a produced light, corresponding reflection shield 102 can be subject to reflected, make the light reflected can be human eye accepted, 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 is the enforcement schematic diagram of existing light-emitting diode lamp tube shown in figure, as figure, existing light-emitting diode lamp tube 103 upper limb, there is an exiting surface 1031 of corresponding with reflection shield 102 and transparent shape, in light-emitting diode lamp tube 103, group is provided with a circuit substrate 1032, and be arranged at below exiting surface 1031, again, light-emitting diode lamp tube 103 lower edge group is provided with the heat-radiating substrate 1033 used 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 reflects, some light can reflex on the heat-radiating substrate 1033 of light-emitting diode lamp tube 103, and then some light is blocked, cause below light-emitting diode lamp tube 103 and form a shade block, the problem that luminous intensity is inconsistent can be caused during illumination, 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.
Summary of the invention
Because above-mentioned problem, the present invention is according to the experience being engaged in relevant industries and light-emitting diode lamp tube design for many years, and carry out studying and improveing for light-emitting diode lamp tube and light ray reflection structure thereof, the phase can design the entity products that can solve the problem; Edge this, main purpose of the present invention is to provide a kind of directly can 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 invention, it mainly to be formed or group is provided with one towards the reflecting layer at fluorescent tube center in the periphery of a body, and complete mutual group with a radiating seat and body and establish, again, radiating seat upper set is provided with the light emitting module that is laid with the circuit substrate of at least two light emitting diodes, by the reflex that described reflecting layer is formed, the light that light emitting diode can be made to launch is by after reflective layer reflects, be dissipated into further outside fluorescent tube, to form a reflective indirect light source, and then make the light shone 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, with the heat energy produced during light emitting diode action, 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 by after this reflective layer reflects, forms a reflective indirect light source.
Preferably, set portion as a chute for this relative group of this radiating seat, after can slipping into for this group portion of establishing of this body, complete relative group and establish.
Preferably, this group portion of establishing of this body is chute-like, and this radiating seat is tabular.
Beneficial effect of the present invention is, by said structure, the present invention really can reach and provide a kind of and directly can produce reflective indirect light source and the object of the good reflection type light-emitting diode diode lamp tube of radiating effect.
