The invention provides the underwater LED lamp of a kind of high sealing height heat radiation, comprise the LED light module that cross section is half elliptic lamp housing, light-passing board and is arranged in lamp housing, described lamp housing one end is provided with circular open, described envelope inner wall is positioned at circular open place and is provided with annular slot, described light-passing board coordinates with annular slot, and described slot upper wall and lower wall are equipped with for compressing light-passing board and the waterproof grommet of sealing; The component of described lamp housing and parts by weight are: polypropylene: 100 parts; Phenolic resins: 50-75 part; Polyphenylene sulfide: 15-20 part; Barium stearate: 10-20 part; Aluminium nitride: 3-10 part.The shell of the present invention by adopting special material to make underwater LED lamp, this shell heat dispersion and mechanical performance are all better, and the LED being highly suitable for using under water uses.
Description
Technical field:
The present invention relates to lighting technical field, particularly relate to a kind of underwater LED lamp of high sealing high heat dispersion.
Background technology:
At present, along with the raising of people's living standard, the development of lighting engineering, people take much count of beautifying of environment, and LED underwater lamp is a kind of Landscape Lamp be installed under water, and due to the particularity of environment, underwater lamp is in water for a long time.If sealing effectiveness is bad, be then easy to cause lamp body to damage.
Existing patent document, such as publication number is that the Chinese patent " sealed waterproof LED lamp " of CN201521934U discloses a kind of sealed waterproof LED lamp, it by offering closed hole on base, in closed hole, cushion block is set, cushion block is pressed in closed hole, make LED have good sealing effectiveness.
And for example publication number is the Chinese patent " a kind of hermetically-sealed construction of LED street lamp " of CN201866745U, it discloses a kind of hermetically-sealed construction of LED street lamp, by establishing cover plate in LED upper cover, packing sealing inside cover plate, drier is placed, to reach sealing and moistureproof effect in LED lamp cover.
For another example publication number is the Chinese patent " closed type Multifunctional LED aquatic animals lamp " of CN202708807U, it discloses a kind of closed type Multifunctional LED aquatic animals lamp, by arranging groove in U-shaped aluminum hull openend, light cover and groove gap-fill encapsulant and several LED ultraviolet lights are installed on LED circuit substrate, make LED good sealing effect and there is bactericidal effect.
The mode that above-mentioned patent all adopts structure to improve makes the sealing property of LED obtain very large improvement, but LED sealing property is better, then to distribute speed poorer for LED heat, because air can not effectively can not take away in LED internal flow the heat that LED produces.The LED of above-mentioned good seal performance will inevitably produce the problem of heat dispersion.
Summary of the invention:
Technical problem to be solved by this invention is, for the above-mentioned deficiency of prior art, provides the underwater LED lamp of a kind of high sealing height heat radiation.
The technical solution adopted in the present invention is: the underwater LED lamp of a kind of high sealing height heat radiation, comprise the LED light module that cross section is half elliptic lamp housing, light-passing board and is arranged in lamp housing, described lamp housing one end is provided with circular open, described envelope inner wall is positioned at circular open place and is provided with annular slot, described light-passing board coordinates with annular slot, and described slot upper wall and lower wall are equipped with for compressing light-passing board and the waterproof grommet of sealing; The component of described lamp housing and parts by weight are:
The present invention adopts polypropylene and phenolic resins as matrix material, fill simultaneously polyphenylene sulfide, barium stearate and aluminium nitride make with modified polypropene and phenolic resins the mechanical performance of the LED shell finally prepared and heat dispersion good.
Polypropylene self has excellent decay resistance and higher serviceability temperature, and it makes the mechanical performance of material be protected as matrix material.
Phenolic resins and polypropylene coordinate not only to play to be strengthened polypropylene mechanical performance but also other fillers can be made better to coordinate with polypropylene and react.
Polyphenylene sulfide, barium stearate and aluminium nitride improve the heat dispersion of the LED shell finally prepared jointly.Wherein polyphenylene sulfide can also improve compatibility and the processability of material, reduces the density of material.
Further, the component of described lamp housing and parts by weight are:
Further, the outwardly camber of described light-passing board.
Further, the draw ratio of described aluminum nitride particle is (10-15): 1.
When aluminium nitride is not the spherical particle powder of employing routine but adopts the particle with certain draw ratio to make aluminium nitride as filler, heat conductivility is better.
Further, described lamp housing is prepared in the following way:
S1: after joining get raw material according to said ratio, mix in banbury and be heated to 220 to 250 DEG C;
S2: the demoulding obtains described lamp housing.
The preparation method of lamp housing of the present invention is simple, without the need to the injection molding process of complexity, and can change recipe ingredient and proportioning at any time according to different product demands.
The shell of the present invention by adopting special material to make underwater LED lamp, this shell has good heat dispersion and mechanical performance, and the LED being highly suitable for using under water uses.
Accompanying drawing illustrates:
Fig. 1 is the sectional view of high sealing underwater LED lamp of the present invention;
Fig. 2 is the preparation flow schematic diagram of lamp housing in LED of the present invention.
As shown in the figure: 1, lamp housing; 2, light-passing board; 3, LED light module; 4, slot; 5, waterproof grommet.
