On a branch road on the LED lamp that the application provides, series connection is provided with three LED and a current-limiting resistance, current-limiting resistance is set and can effectively protects LED not burnt, and guarantees the normal use of light fixture.
Simultaneously, be provided with a plurality of circular salient points on the lampshade of the LED light fixture that the application provides, better reflect light, do not make the user feel to dazzle the eyes dazzling.
Certainly, arbitrary product of enforcement the application might not need to reach above-described all advantages simultaneously.
The accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, below will the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
The structural representation that Fig. 1 is a kind of LED light fixture of the application lamp body;
The circuit diagram that Fig. 2 is a branch road on the application's aluminium base;
The structural representation that Fig. 3 is a kind of LED light fixture of the application lampshade.
The specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making under the creative work prerequisite the every other embodiment obtained, belong to the scope of protection of the invention.
Refer to Fig. 1, the lamp body structure schematic diagram that it shows a kind of LED light fixture that the application provides, comprise lamp holder 1 and lamp body 2, and wherein, lamp body 2 is cuboids and is hollow structure.Four sides of lamp body 2 and bottom form by LED aluminium base 3.Post a plurality of LED lamp bars on aluminium base 3, wherein, three LED4 and a current-limiting resistance 5 are composed in series a branch road, be installed in parallel N bar branch road and directly be soldered to the driving power plate on aluminium base 3.Wherein, different settings is carried out in the use occasion of the LED light fixture that the number of parallel branch can provide according to the application, N=39 in the present embodiment, and all branch roads are evenly distributed on the aluminium base of lamp body.
Using aluminium base 3 as the main material of lamp body, can realize that the heat that the chip of LED4 produces derives rapidly, and then extend the service life of LED4.
In this application, multiple branch circuit is carried out to parallel connection, in the time of can guaranteeing the LED4 damage on one of them branch road, residue still works with the branch road of this branch circuit parallel connection, and then does not affect the normal use of LED light fixture.
