Abstract

The invention provides an insulated high pressure light-emitting diode (LED) lamp bulb which is suitable for the lighting field. The insulated high pressure LED lamp bulb comprises a thermal dissipation main body, a lamp cover and a lamp holder, wherein the lamp cover is used for clamping the port on the top portion of the thermal dissipation main body, the lamp holder is arranged at the bottom end of the thermal dissipation main body, a lamp plate is further arranged in the insulated high pressure LED lamp bulb, a welding disc on the conducting layer of the lamp plate is connected with the lamp holder through conductor wires, thermal dissipation fixed sheets are pasted on the bottom of the lamp plate through heat conduction insulated double faced adhesive tapes, the thermal dissipation fixed sheets are nested into the port on the top portion of the thermal dissipation main body and are contacted with the thermal dissipation main body tightly, decoration sheets are arranged between the outer periphery of the lamp plate and the thermal dissipation fixed sheets and are used for completely and safely insulating the lamp plate and the thermal dissipation fixed sheets. According to the insulated high pressure LED lamp bulb in the technique scheme, not only is a thermal dissipation problem solved, but also a high pressure resistance test is passed by products, and safety performance of the products is ensured.

Description

technical field [0001] The invention belongs to the field of lighting, in particular to an insulated high-voltage LED light bulb. Background technique [0002] High-voltage LED bulbs are a development trend of LED lighting. The LED light board inside the bulb is directly electrically connected to a voltage of 220~240V or 100~120V. Due to the structural design of high-voltage LED bulbs, no transformer is used to convert high voltage to low voltage. , The use of raw materials is reduced in structure, and the design purpose of "resource-saving and environment-friendly" is achieved, which is more in line with the requirements of the EU ERP ecological design directive. On the other hand, it can greatly save the production cost and transportation cost of bulbs. However, due to the high-voltage power supply used directly, the electrical safety standards for such LED bulbs have relatively high requirements. On the basis of ensuring absolute electrical insulation safety, in order to ...
