Problems solved by technology

Due to the particle dust attached to the air in the surrounding environment during the operation of the product, a large amount of particle dust enters the inner cavity of the LED lamp bead and lens combination, resulting in a gradual decrease in the luminous flux of the LED projection lamp and unclear projection patterns.

Abstract

The invention discloses an LED projection lamp. The LED projection lamp comprises an LED lamp bead, an LED driving board, a lens assembly and a casing, wherein a partition board is arranged in the casing and divides the inner part of the casing into a hollow cavity and a heat dissipation cavity; the LED lamp bead, the LED driving board and the lens assembly are located in the hollow cavity; a heat dissipation device, a fan rack and a fan are arranged in the heat dissipation cavity; the heat dissipation device and the LED lamp bead are located on the front surface and the back surface of the partition board respectively; the fan is mounted on the fan rack; an air inlet and an exhaust port are formed in the casing and are both communicated with the heat dissipation cavity. The LED projection lamp cannot be influenced by attached particles and dust in air in the ambient environment during using.

Description

technical field [0001] The invention relates to an LED projection lamp. Background technique [0002] LED projection lamp is a device used to project patterns onto curtains or other backgrounds for display, and is widely used in places such as people's lives or work. [0003] The air inlet and outlet of the heat dissipation design of the LED projection lamp are in the internal space of the combination of LED lamp beads and lenses, and the combination of LED lamp beads, electronic components, and lenses becomes a channel for air convection. Due to the attachment of particulate dust in the air of the surrounding environment during the operation of the product, a large amount of particulate dust has entered the inner cavity of the LED lamp bead and lens combination, resulting in a gradual decrease in the luminous flux of the LED projection lamp and unclear projection patterns. The accumulation of particulate dust, which becomes the electrolyte of electronic components, gradual...
