Description

Technical Field

[0001] This utility model belongs to the field of projection speaker technology, and specifically relates to a dynamic projection lamp and speaker. Background Technology

[0002] Traditional projection lamps consist of an LED light source, a condenser lens, a film, and a projection lens. The condenser lens, film, and projection lens are arranged sequentially along the light output axis of the LED light source. The light emitted by the LED light source passes through the condenser lens and then shines parallel onto the film. After passing through the film, the light is projected outward through the projection lens, thus projecting the pattern on the film onto the outside world. However, the projected pattern is static, which can easily cause visual fatigue with prolonged use.

[0003] Therefore, in order to make the projected pattern present a dynamic effect, based on the above structure, the LED light source, condenser lens, film and projection lens are arranged into multiple small modules. The array pattern on the film is made into a continuously moving pattern. By controlling the on and off of the array LED light source, the projected pattern is controlled. The continuous on and off can project a dynamic pattern, forming an effect similar to FLASH video. However, once the above projection lamp is manufactured, the film will be fixed inside the projection lamp and cannot be replaced. After long-term use, it will also cause visual fatigue. Utility Model Content

[0004] The main objective of this invention is to provide a dynamic projection lamp. By designing the film array assembly as a tray shape, a pull-out groove is provided on the side of the condenser lens array assembly near the projection lens array assembly. The pull-out groove is perpendicular to the light path direction within the condenser lens array assembly and communicates with the projection lens array assembly. The film array assembly can be pulled into the pull-out groove. Using this solution, by controlling the on / off state of the LED light source array assembly, the projected pattern can change within a selected range. This overcomes the problem that traditional projection systems with separate light paths produce static projection patterns, leading to visual fatigue after prolonged use. Furthermore, the film array assembly is replaceable, allowing for changes to the projected pattern content. This overcomes the problem that while existing projection lamps using projection arrays can achieve a FLASH video effect, the projected content cannot be changed, leading to visual fatigue after prolonged use, thus improving the user experience.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0032] Traditional projection lamps consist of an LED light source, a condenser lens, a film, and a projection lens. The condenser lens, film, and projection lens are arranged sequentially along the light output axis of the LED light source. The light emitted by the LED light source passes through the condenser lens and then shines parallel onto the film. After passing through the film, the light is projected outward through the projection lens, thus projecting the pattern on the film onto the outside world. However, the projected pattern is static, which can easily cause visual fatigue with prolonged use.

[0033] Therefore, in order to make the projected pattern present a dynamic effect, based on the above structure, the LED light source, condenser lens, film and projection lens are arranged into multiple small modules. The array pattern on the film is made into a continuously moving pattern. By controlling the on and off of the array LED light source, the projected pattern is controlled. The continuous on and off can project a dynamic pattern, forming an effect similar to FLASH video. However, once the above projection lamp is manufactured, the film will be fixed inside the projection lamp and cannot be replaced. After long-term use, it will also cause visual fatigue.

The film array assembly 23 can be pulled into the pull-out groove 221.

[0036] In this invention, by adopting the above-mentioned solution, the on / off state of the LED light source array assembly 21 is controlled, thereby allowing the projected pattern to change within a selected range. This overcomes the problem that the projected pattern of traditional projection systems with separate light paths is static, which can easily cause visual fatigue after prolonged use. Furthermore, the film array assembly 23 is replaceable, thus achieving the effect of changing the content of the projected pattern. This overcomes the problem that although the projection lamps using projection arrays in the prior art can achieve the effect of FLASH video, the projected content cannot be changed, and visual fatigue can also occur after prolonged use, thereby improving the user experience.
