Preferably, described LED also include be used for by described power supply be blocked in power source cavity be arranged on it is describedDividing plate in upper lid, described dividing plate keep apart described power source cavity and described lower cover.
Preferably, described light source board includes the light source Slab element of multiple strips, multiple described light source Slab elementsLateral edges are folding successively to connect the tubular for forming upper and lower opening.Light source board can also be flexible light source plate.
Preferably, described lower cover also includes bottom wall, and the first downwardly convex bulge loop is provided with described bottom wall and is setThe second downwardly convex bulge loop on the outside of the first bulge loop is put, a clamping is formed between described the first bulge loop and the second bulge loopGroove, the upper end of described light source board are fastened in described buckling groove.
Preferably, opening is formed in the first bulge loop of described bottom wall.
Preferably, the bottom wall of described diffuser, which is provided with, has set up the 3rd bulge loop, the lower end of described light source boardEnclosed in the 3rd described bulge loop, and the medial surface phase of the lateral surface of the lower end of described light source board and the 3rd described bulge loopContact.
Preferably, the bottom of described diffuser is provided with multiple air-vents, multiple described air-vents formed it is netted, andIt is arranged in the 3rd described bulge loop.
Preferably, described light source Slab element is aluminium base.
Preferably, described lower cover is connected by screw connection or bolted mode with described upper lid.
Due to the use of above technical scheme, the application has the following advantages that compared with prior art：
LED described herein, is not provided with radiator, using light source board from radiate, significantly save resource and intoThis.The heat emission hole of the air-vent of described diffuser, the heat-dissipating space of light source board and described lower cover is formed can be for outside emptyThe gas channel that gas passes sequentially through.When using LED described herein, extraneous air is entered by air-vent, by dissipatingHeat space, flow up, flow to from the heat emission hole of lower cover in external environment condition, take away the heat in LED.

Embodiment
The application is described in further details below in conjunction with specific embodiment.It should be understood that these embodiments are to be used to sayGeneral principle, principal character and the advantage of bright the application, and the application is not limited by the scope of following examples.Adopted in embodimentImplementation condition can do further adjustment according to specific requirement, and unreceipted implementation condition is usually the bar in normal experimentPart.
It is the structural representation of the LED of the application as shown in Fig. 1~2, it includes upper lid 2, is connected to described upper lidThe lower cover 5 of 2 lower ends, described lower cover 5 are connected by screw connection or bolted mode with described upper lid 2.It is describedUpper lid 2 in form power source cavity, power supply 3 is installed, described LED also includes being used for described electricity in described power source cavitySource 3 be blocked in power source cavity be arranged on described upper lid 2 in dividing plate 4, described dividing plate 4 by described power source cavity with it is describedLower cover 5 keep apart.The upper upper end of lid 2 is connected with joint 1.
Described lower cover 5 includes side wall, multiple heat emission holes 54 is provided with described side wall, described heat emission hole 54 is in lengthBar shaped, circumferentially it is opened in the side wall of described lower cover 5.The lower end of described lower cover 5 is connected with the tubular of upper and lower openingLight source board 6, described light source board 6 include the light source Slab element 61 of multiple strips, the side of multiple described light source Slab elements 61Edge is folding successively to connect the tubular for forming upper and lower opening.Described light source Slab element 61 is the good aluminium base of heat-conducting effectPlate.LED light source 7 is welded with described light source board 6.The radiating that above-below direction is formed among the light source board 6 of described tubular is emptyBetween.
