Description

A kind of multiple circles LED modules

Technical field

The utility model is related to a kind of multiple circles LED modules.

Background technology

The common light source of industry is all that single group lights, and can only fix light-emitting area, its angle is with designed size and can not change Become, the commodity size of such as user's irradiation, which changes light fixture, to be changed, not enough if the excessive light intensity of hot spot, and the big light intensity of hot spot needs enough It is more high-power, use limited.Therefore, it is necessary to design a kind of multiple circles LED modules.

Utility model content

Technical problem to be solved in the utility model is to provide a kind of multiple circles LED modules, multiple circles LED modules tool There is multigroup LED, light-emitting area can be changed, flexibility is good.

The technical solution of utility model is as follows：

A kind of multiple circles LED modules, including module body, are distributed on module body provided with N group concentric-ring patterns multi-turn Isolation strip provided with insulation between LED, 2 groups of adjacent LEDs；N+1 connection terminal is additionally provided with module body；N >=2, And N is integer；

Each group of LED includes multiple LEDs of series connection；

N groups LED forms a LED string by N+1 connection terminal by the order forward direction series connection of both positive and negative polarity；Both positive and negative polarity The positive series connection of order be that adjacent LED positive pole connects negative pole and is sequentially connected in series, referring to Fig. 2.

Described N=3, module body is square shape sheet, and connection terminal is 4, is separately positioned on 4 angles position of module body.

Every group of LED includes at least three LED.

The outside of one group of LED of outmost turns is provided with isolation strip.

Beneficial effect：

One light source, is divided into some groups by multiple circles LED modules of the present utility model, point circle since first group of center, Successively to external expansion, lighted when lighting by central. set and outer ring packet superposition, increase fermentation product, by changing lamp bead light-emitting area It is to change light extraction hot spot to change the focal length of lens.

Light source first lap lights, and smooth surface is smaller, and the hot spot got by lens is smaller, when the second circle is lighted again with the One circle together lighted by superposition, and first lap and the second circle light simultaneously, and light-emitting area superposition increase is also and then increased by lens flare Greatly, when the 3rd punctuates bright, it is superimposed with the one or two circle, hot spot further increases, lens flare continues to increase, and reaches by packet The principle in light source luminescent face is controlled to change the spot size of projection.

Change light source luminescent area is lighted in packet shown in above technology, so as to change lighting angle.

Brief description of the drawings

Fig. 1 is the structural representation of multiple circles LED modules；

Fig. 2 is the circuit theory diagrams of multiple circles LED modules.

Label declaration：First group of LED of 1-, second group of LED of 2-, the 3rd group of LED of 3-, 4- connection terminals, 5- isolation Band.

Embodiment

The utility model is described in further details below with reference to the drawings and specific embodiments：

Embodiment 1：Such as Fig. 1 ~ 2, a kind of multiple circles LED modules, including module body are same provided with 3 groups on module body The LED of heart round type multi-turn distribution, is first group of LED 1, second group of LED 2 and the 3rd group of LED 3 respectively；Adjacent 2 groups Isolation strip 5 provided with insulation between LED；4 connection terminals 4 are additionally provided with module body.

Each group of LED includes 3 LEDs of series connection；

3 groups of LEDs form a LED string by 4 connection terminals by the order forward direction series connection of both positive and negative polarity；Both positive and negative polarity The positive series connection of order is that adjacent LED positive pole connects negative pole, is sequentially connected in series, referring to Fig. 2.

4 connection terminals are separately positioned on 4 angles position of module body.

For this multiple circles LED modules, it can control only to open any group of LED with power-up mode（Such as in BW and BN Between power up）, or open 2 groups（Power up, or powered up between BW and BZ such as between B+ and BN）Or 3 groups of LEDs（In B+ and BZ Between power up）, flexibility is good.
