Luminous energy direct projection penetrates the illuminating lamp of cell-shell
Technical field
The present invention relates to lighting field, particularly a kind of luminous energy direct projection penetrates the illuminating lamp of cell-shell.
Background technology
Rapidly, the ball bubble such as made, comes into huge numbers of families in LED technology development.
Ball bubble on market, its product is single, and cell-shell shape is semicircle, is fixed on lamp body with glue, the space that in cell-shell, formation one is airtight, and internal-external temperature difference is very large, and cause localized hyperthermia LED downright bad, meanwhile, cell-shell internal-external temperature difference great Yi produces water smoke.
Summary of the invention
In order to solve above-mentioned existing technical problem, the invention provides the illuminating lamp that a kind of luminous energy direct projection penetrates cell-shell, its cell-shell covers at the second radiator, and the inner air and outer air of cell-shell is communicated with, to reduce the internal-external temperature difference of cell-shell.
The present invention solves above-mentioned existing technical problem, provides a kind of luminous energy direct projection to penetrate the illuminating lamp of cell-shell, comprises lamp holder, power module, the first radiator, the second radiator, lamp plate and cell-shell; Described first radiator one end connects described lamp holder, the other end connects described second radiator; The space that described power module is dissolved in described lamp holder, described first radiator surrounds; Described second radiator has cambered surface, and described lamp plate is arranged at described cambered surface; Described cell-shell covers at described second radiator, and the luminous point of described lamp plate is connected to the inwall of described cell-shell.
Further improvement of the present invention is as described below.
The inwall of described second radiator has fin.
Described cambered surface has pintongs.
The pintongs of cambered surface is symmetrical set.
Described second radiator is threadedly connected to described first radiator.
The local of described cambered surface is attached at described cell-shell.
The opening of described cell-shell is connected to described first radiator.
In smooth continuous transition between described cell-shell and described first radiator.
Described power module is through being electrically connected between wire and described lamp plate.
Described lamp plate is flexible PCB.
Compared to prior art, the invention has the beneficial effects as follows: cell-shell covers at the second radiator, the inner air and outer air of cell-shell is communicated with, thus reduces the internal-external temperature difference of cell-shell.Meanwhile, cambered surface local is attached at cell-shell, and like this, the heat that cambered surface absorbs directly is radiated outside in air through cell-shell.

Detailed description of the invention
Illustrate below in conjunction with accompanying drawing and detailed description of the invention the present invention is further described.
As depicted in figs. 1 and 2, a kind of luminous energy direct projection penetrates the illuminating lamp of cell-shell, comprises lamp holder 11, power module, the first radiator 13, second radiator 14, lamp plate 15 and cell-shell 16; First radiator 13 one end connects lamp holder 11, the other end connects the second radiator 14; Power module is dissolved in the space that lamp holder 11, first radiator 13 surrounds; Second radiator 14 has cambered surface, and lamp plate 15 is arranged at cambered surface; Cell-shell 16 covers at the second radiator 14, and the luminous point of lamp plate 15 is connected to the inwall of cell-shell 16.Cell-shell 16 covers at the second radiator 14, and the inner air and outer air of cell-shell 16 is communicated with, thus reduces the internal-external temperature difference of cell-shell 16.Its operation principle is, when lamp holder 11 and lamp socket are connected, meanwhile, connect civil power, the delivery of electrical energy of lamp holder 11, to power module, is processed by power module, and the delivery of electrical energy after process is to lamp plate 15, and luminous point emits beam.The heat that lamp plate 15 produces is absorbed by the second radiator 14, and this second radiator 14 by a part of heat conduction to being connected the first radiator 13 with it, also can be able to transfer in the inside and outside air be communicated with.
In order to improve the radiating effect of the second radiator 14 itself, the inwall of the present invention second radiator 14 has fin.In order to improve the outward appearance visual sense of the present invention's illumination, its cambered surface has pintongs, also can adopt two lobes, three lobes or many lobes, generally, be symmetrical set.
The present invention second radiator 14 is threadedly connected to the first radiator 13, and heat conduction can be convenient in its threaded connection place.
The present invention, the local of cambered surface is attached at cell-shell 16, and adopt cambered surface local to be attached at cell-shell 16, like this, the heat that cambered surface absorbs directly is radiated outside in air through cell-shell 16, improves radiating efficiency further.
The opening of cell-shell 16 of the present invention is connected to the first radiator 13, and in smooth continuous transition between cell-shell 16 and the first radiator 13, its outward appearance can be pyriform or other shape.
Power module of the present invention, through being electrically connected between wire and lamp plate 15, passes through for the ease of wire, the first radiator 13 tool through hole, and wire wears wherein, and also in order to fit tightly with cambered surface, lamp plate 15 of the present invention is flexible PCB.
Above content is in conjunction with concrete preferred embodiment further description made for the present invention, can not assert that specific embodiment of the invention is confined to these explanations.For general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, some simple deduction or replace can also be made, all should be considered as belonging to protection scope of the present invention.
