Summary of the invention

The purpose of the utility model is in order to overcome the silica gel waterproof sealing gasket unreasonable structure that the existing module that is used on the LED light fixture exists; Influence the problem of module luminous efficiency and water-tight performance; A kind of novel structure is provided; Luminous efficiency is stable, and water-tight property is good is used for the module on the LED light fixture.

In order to realize the foregoing invention purpose, the technical scheme below the utility model has adopted:

A kind of module that is used on the LED light fixture comprises radiating block, pcb board, a plurality of LED, silica gel sealing water proof ring, lens and fixture from top to bottom successively, and pcb board is fixed on the radiating block, and a plurality of LED are fixed on the pcb board; The middle part of silica gel sealing water proof ring is provided with a through hole that supplies all LED to pass, and the through hole of silica gel sealing water proof ring and the waterproof main body between the outer ledge are provided with the fixture installing hole; The outer contour shape coupling of pcb board, silica gel sealing water proof ring and lens, the fixture installing hole that fixture passes rims of the lens and silica gel sealing water proof ring is fixed on lens, silica gel sealing water proof ring and pcb board on the radiating block.

As preferably, the outline of said pcb board, silica gel sealing water proof ring and lens is square or circular, and the through hole at silica gel sealing water proof ring middle part is square hole or circular hole, produces very convenient.

As preferably, said lens are made up of installing plate and the local lens of a plurality of LED, and the outer contour shape of the outer contour shape of installing plate and pcb board and silica gel sealing water proof ring matees; The position of the local lens of a plurality of LED is corresponding with a plurality of LED couplings on the pcb board; And the local lens of LED bottom is protrusion downwards; Its inboard is provided with the cavity volume that holds LED that opening makes progress; The through hole that the bottom of LED is passed on the silica gel sealing water proof ring is in the cavity volume of the local lens of LED, and the equipped relation of cavity volume of LED and the local lens of LED more helps the fastness that each parts are connected.

As preferably, be provided with heat transfer sheet between said radiating block and the pcb board, heat-transfer effect is better.

As preferably, said radiating block is provided with installed part, and module is fixed on the shell of LED light fixture through installed part.

As preferably, said fixture is a screw.

A kind of module that is used on the LED light fixture by the technique scheme design; The novel structure of silica gel sealing water proof ring; Through hole at the middle part of silica gel sealing water proof ring supplies all LED to pass, relatively with existing structure decrease the use amount of silica gel material, reduced production cost; The silica gel sealing water proof ring carries out water-tight through the waterproof main body between through hole and the outer ledge; The mode of passing the fixture installing hole through fixture even if make silica gel sealing water proof ring heating distortion can not be subjected to displacement the effect that does not promptly influence its water-tight, can not shelter from the luminous efficiency that LED influences LED with firm the fixing of silica gel sealing water proof ring yet yet.In sum, this advantage that is used for the module on the LED light fixture is a novel structure, and luminous efficiency is stable, and water-tight property is good.
