High-power LED bulb lamp

Abstract

The invention relates to the field of bulb lamps, and discloses a high-power LED bulb lamp. The bulb lamp comprises a reflector, a central through pipe is arranged in the reflector, a first light-emitting assembly is slidably arranged on the outer side wall of the central through pipe, a heat dissipation assembly is connected to the top of the central through pipe, a sensing assembly is arranged at the top of the heat dissipation assembly, a locking head is connected to the bottom of the central through pipe, and a detachable filter screen is arranged at the bottom of the locking head. The first light-emitting assembly of the bulb lamp can move on the outer side wall of the center through pipe, and focusing change of lower light is achieved; by arranging the sensing assembly, the temperature of the air outlet of the bulb lamp can be sensed in time, and the working state of the bulb lamp is judged; by arranging the detachable filter screen at the bottom of the bulb lamp, large-particle matter in air is filtered out, and dust is prevented from attaching to the bulb to affect the intensity of light; and a protruding block is arranged on the inner side wall of the center through pipe, heat generated by the first light-emitting assembly is transmitted to a radiator in the first time, and the situation that the first light-emitting assembly is burnt out due to the too high temperature is avoided.

Description

【Technical field】 [0001] The invention relates to the field of bulb lamps, in particular to a high-power LED bulb lamp. 【Background technique】 [0002] The internal light source of the bulb lamp is LED lamp beads, which have the characteristics of energy saving, environmental protection, long service life and no flicker, and can better replace incandescent bulbs, but the existing bulb lamps often cannot adjust the focus position of the light source and height, the use is single, and the existing bulb lamps do not know the internal temperature during use, which makes it easy to burn out the internal LED lamp beads under long-term working conditions, and the existing bulbs The lamp needs to draw fresh air from the outside when it dissipates heat. The air entering the bulb will bring a certain amount of dust and large particles of impurities, especially in some harsh working environments, which will cause impurities to adhere to the light source or At the reflector, the irradi...
