Problems solved by technology

This method improves the weather resistance, airtightness, working life and reliability of LED light bar products to a certain extent, but the preparation method uses PVC material, TPU material, or a mixture of PVC and TPU, which are all extruded through extrusion molding. Molded on the main body of the LED light bar, the process is relatively cumbersome, and the resistance to mechanical shock and vibration is poor, and it is easy to break

Abstract

The invention relates to a highly sealed LED light. The highly sealed LED light comprises a light shell (1), a substrate (2), an illuminating module (3), a lightshade (4), a radiator (5), a through hole (6), a sealing ring (6), a press ring (8) and a sealant (9), wherein the sealant (9) is a hydroxyl terminated polydimethylsiloxane modified epoxy resin sealant and is prepared through the reasonable compatibility of a hydroxyl terminated polydimethylsiloxane modified epoxy resin, a filler, an active diluent, a curing agent, a plasticizer, a silane coupling agent and an antifoaming agent. The making method of the highly sealed LED light comprises the following steps: mixing the hydroxyl terminated polydimethylsiloxane modified epoxy resin with the above other raw materials, stirring to prepare a transparent liquid, and uniformly mixing with a curing agent A uniformly stirred at room temperature to prepare a mixture used for the sealing connection of the circumference of the substrate (2) and the light shell (1) in order to make the highly sealed LED light. The highly sealed LED light made in the invention has the advantages of realization of bearing high-strength mechanical impact and shock, difficult fragmentation, simple sealing connection technology, good water and dust resistances, and the like.

Description

technical field [0001] The invention relates to an LED lamp, in particular to a highly sealed LED lamp. Background technique [0002] LED lights have the advantages of energy saving and environmental protection, and the development of the lighting industry has become a major trend. Most of the current LED lamps are suitable for traditional fields. For the use environment that requires waterproof and dustproof, the current LED lamps may not be very suitable, so the LED lamps of the prior art have a long service life in a humid or dusty environment. shorter. [0003] The preparation of highly sealed LED lamps has been reported in the prior art. For example, the Chinese invention patent (publication number: CN102628562A) relates to a LED light bar with a fully waterproof glue filling structure and a manufacturing method. The manufacturing method is to extrude and mold PVC material, TPU material, or a mixture of PVC and TPU on the main body of the LED light bar through an ext...
