Abstract
The utility model discloses an LED (Light Emitting Diode) light emitting device, which comprises a columnar bracket as an electrode and an insertion rod. The columnar bracket and the insertion rod are assembled together. An insulating layer is arranged between the columnar bracket and the insertion rod. The LED light emitting device is characterized in that at least one spirally arranged light emitting light source is installed on the side wall of the columnar bracket; the light emitting light source is composed of a plurality of LED chips; the plurality of LED chips are connected with the columnar bracket and the insertion rod in series and/or in parallel; and the LED chips are installed on the top of the insertion rod. According to the LED light emitting device disclosed by the utility model, more uniform light emitting arc can be obtained; simultaneously, a dark region on the top can be avoided; therefore, the light emitting efficiency of the LED light emitting device can be ensured.
Description
Technical field
The utility model relates to a kind of light-emitting device, particularly a kind of LED light-emitting device.
Background technology
LED is as light source of new generation, and its development very rapidly.Along with the maturation day by day of LED technology, LED is more and more wider in the application in the display lighting and the field of decoration.Tradition LED light-emitting device comprises column support, inserted link and a plurality of led chip, and the encapsulating face of the column support of traditional LED light-emitting device is a planar structure, if want to improve the uniformity of luminous arc; Just need guarantee that led chip is attached to the middle position of encapsulating face, and the volume of led chip and column support is less, accurately technology difficulty will certainly be strengthened in the location; Reduce production efficiency; Improve production cost, traditional LED light-emitting device does not have at the top of inserted link led chip to be set simultaneously simultaneously, though therefore it can accomplish to have 360 degree luminous arcs; But the dim light zone can appear in its top, influences the illumination effect of LED light-emitting device.
Summary of the invention
In order to overcome the deficiency of prior art, the utility model provides a kind of not only to have more uniform 360 degree luminous arcs, top but also the regional LED light-emitting device of dim light can not occur.
The utility model solves the technical scheme that its technical problem adopted:
A kind of LED light-emitting device; Comprise column support and inserted link as electrode, column support and inserted link are assembled together, and are provided with insulating barrier between column support and the inserted link; The sidewall that it is characterized in that said column support is equipped with at least one illuminating source that be provided with twist; Said illuminating source is made up of a plurality of led chips, and a plurality of led chips are connected with inserted link with the column support through the mode of series connection and/or parallel connection, and the top of said inserted link is equipped with led chip.
The cylindrical structure of above-mentioned column support.
On the above-mentioned column support lens are installed, said led chip is encapsulated in the lens.
Above-mentioned column support is provided with pin, and pin is provided with the screw thread that is connected with lamp socket.
The beneficial effect of the utility model is: the utility model not only is equipped with helical illuminating source at the sidewall of column support; And led chip is installed at the top of inserted link; Thereby can not only obtain more uniform luminous arc; Can avoid simultaneously occurring the dim light zone, thereby ensure the luminous efficiency of LED light-emitting device at the top.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified:
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the cutaway view of Fig. 1.
The specific embodiment
With reference to Fig. 1, Fig. 2, the disclosed a kind of LED light-emitting device of the utility model comprises column support 1 and inserted link 2 as electrode; Column support 1 cylindrical structure shown in the figure; Column support 1 is assembled together with inserted link 2, is provided with insulating barrier 3 between column support 1 and the inserted link 2, at the sidewall of column support 1 three illuminating sources of setting twist is installed; Each illuminating source is made up of a plurality of led chips 4; A plurality of led chips are connected with inserted link 2 with column support 1 through the mode of series connection and/or parallel connection, at the top of inserted link 2 led chip 4 are installed, and the utility model can not only obtain more uniform luminous arc like this; Can avoid simultaneously occurring the dim light zone, thereby ensure the luminous efficiency of LED light-emitting device at the top.
As shown in the figure, lens 5 are installed on the column support 1, led chip 4 is encapsulated in the lens 5, and the light direct projection behind cylindrical lens optically focused of sending of LED wafer is gone out like this, the utlity model has good spotlight effect thereby make
Certainly; The utility model is not limited to above-mentioned embodiment; The utility model also can have other structural change, also can be provided with one, two or many like illuminating source, and the column support is other shape or the like also; As long as it reaches the technique effect of the utility model with essentially identical means, all should belong to the protection domain of the utility model.
