Abstract
The utility model discloses a high water proofness LED light source module, including circuit board and the LED chip of encapsulation on the circuit board, still wrap up in the watertight subassembly of circuit board and LED off -chip, the watertight subassembly includes the base, encircles the barrel of base and covers the printing opacity cover at the barrel top, the below of base is equipped with the waterproof cavity of multiseriate, through wire through -hole intercommunication between the adjacent waterproof cavity of same row, the wire and external intercommunication of circuit board through piercing through the wire through -hole. The mode of the waterproof cavity of utility model adoption pierces through the position to the wire and carries out the watertight processing, makes LED light source module can effectively prevent the infiltration, and then the circuit structure of protection LED light source module, prolongs the life of LED light source module, heat dispersion influence to LED chip, circuit board is low, is favorable to the thermal discharge of LED light source module.
Description
Technical field
The utility model relates to a kind of LED light source module, is specifically related to a kind of high watertightness LED light source module.
Background technology
LED chip is widely used in the portable light sources such as lantern, emergency light, desk lamp, flashlight, searchlight because its volume is little, energy consumption is low, light efficiency is strong.Portable light source is often used in outdoor activities, and because outdoor environment is changeable, LED light source easily damages its internal circuit structure because of infiltration, causes the decline in service life.In prior art, the mode of conventional encapsulating carries out water-proofing treatment to LED light source module, needs colloid to dig up just can keep in repair when safeguarding, very inconvenient, and technique is very complicated.And the gap of the sealing structure light source die assembly housings such as sealing ring need be adopted without encapsulating waterproof technique, cause LED and pcb board heat not to conduct or to scatter, radiating effect is bad.In addition, wiring board still needs wire by penetrating shell and power lights anatomical connectivity, and the position that wire penetrates then becomes the district occurred frequently of infiltration phenomenon.
In view of this, exploitation is a kind of produces and maintenance efficient rate, and the LED light source module that watertightness is high necessitates.
Utility model content
In view of this, the open a kind of production of the utility model and maintenance efficient rate, the LED light source module that watertightness is strong.
The purpose of this utility model is achieved through the following technical solutions: a kind of high watertightness LED light source module, comprises wiring board and encapsulation LED chip in the circuit board, it is characterized in that: also comprise the watertight assembly be wrapped in outside wiring board and LED chip; Described watertight assembly comprise pedestal, around pedestal cylindrical shell and cover the diffuser at cylindrical shell top; The below of described pedestal is provided with multiple row watertight cavity group, is provided with multiple watertight cavity in watertight cavity group; Be communicated with by wire through-hole between the adjacent watertight cavity of same watertight cavity group; Described wiring board is in communication with the outside by the wire penetrating wire through-hole.
In the utility model, pedestal and cylindrical shell are formed in one structure, can adopt injection molding.Diffuser is then mounted in the top of cylindrical shell.The utility model to LED light source module encapsulating, only need not take diffuser apart when safeguarding.And the utility model is provided with multiple row watertight cavity group in the below of pedestal, the columns of watertight cavity is relevant to the quantity of wire.Wiring board is then connected with the external world by the wire penetrating watertight cavity.Multiple watertight cavity of same group form the barrier of multi layer waterproof by the air pressure that empty intracavity gas is external, the outside whole watertight cavity of moisture infiltrate can corrode the circuit structure of LED light source module, has comparatively stable waterproof effect.The utility model adopts the mode of watertight cavity to carry out watertight process to wire piercing site, makes LED light source module effectively can prevent infiltration, and then the circuit structure of protection LED light source module, extends the service life of LED light source module.And watertight cavity is only wrapped in outside wire, low on the heat dispersion impact of LED chip, wiring board, be conducive to the discharge of LED light source module heat.In addition, the structure of non-encapsulating is also conducive to reducing maintenance cost of the present utility model.
Further, inside described cylindrical shell, be provided with the seal groove of annular, in described diffuser edge wedging seal groove; The flexible sealant of described seal groove surface coverage; Edge bottom described diffuser is provided with a circle annular boss.
Described elastic sealing layer can select any one existing elastomeric material to make, and as rubber, silica gel etc., effectively can improve the water proofing property of diffuser and cylindrical shell connecting portion.The effect of annular boss extrudes the local of elastic sealing layer, improves the tight ness rating of this regional seal layer, improve waterproof effect further.
Further, the bottom of described annular boss is provided with the projection of multiple del.
Projection can clamp described seal groove, prevents diffuser from sliding.

Fig. 1 is structural representation of the present utility model.
Fig. 2 is the partial enlarged drawing of the utility model cylindrical shell.
Fig. 3 is the partial enlarged drawing of the utility model projection.
Detailed description of the invention
The utility model to be described in further detail below in conjunction with accompanying drawing and embodiment for the ease of it will be appreciated by those skilled in the art that:
Embodiment 1
The present embodiment provides a kind of high watertightness LED light source module, as Fig. 1 and Fig. 2, comprises wiring board 1 and encapsulation LED chip 2 in the circuit board, also comprises the watertight assembly be wrapped in outside wiring board and LED chip; Described watertight assembly comprise pedestal 3, around pedestal cylindrical shell 4 and cover the diffuser 5 at cylindrical shell top; The below of described pedestal is provided with 2 row watertight cavity groups, is provided with 3 watertight cavity 31 in watertight cavity group; Be communicated with by wire through-hole between the adjacent watertight cavity of same watertight cavity group; Described wiring board is in communication with the outside by the wire 6 penetrating wire through-hole.
Further, inside described cylindrical shell 4, be provided with the seal groove 41 of annular, in described diffuser 5 edge wedging seal groove; The flexible sealant 42 of described seal groove surface coverage; Edge bottom described diffuser is provided with a circle annular boss 51.
Further, as Fig. 3, the bottom of described annular boss is provided with the projection 52 of multiple del.
Be more than wherein specific implementation of the present utility model, it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these apparent replacement forms all belong to protection domain of the present utility model.
