Abstract

The utility model relates to an LED pattern lamp, which belongs to a light fitting. The LED pattern lamp comprises an imaging lens, a lamp body shell, an LED light source, an optical effect device, an optical effect drivie stepping motor and a pattern effect device. The optical effect device is connected with an output shaft of the optical effect drive stepping motor. The pattern effect device has a pattern sheet and a pattern tray drive stepping motor, and the pattern sheet is connected with the output shaft of the pattern tray drive stepping motor. After the light projected by the LED light source of the LED pattern lamp passes through a collector lens, the light is converged on the pattern sheet to image via an imaging field lens, and the pattern sheet can be changed via the pattern tray drive stepping motor.

Description

The LED pattern lamp

Technical field

The utility model belongs to a kind of light fixture, mainly is a kind of LED pattern lamp that can arbitrarily change projective patterns.

Background technology

LED is because of the optical characteristics of himself, LED light fixture long service life, and power consumption is extremely low; Owing to belong to cold light source, the LED light fixture is very safe, can realize automatic seven color conversions: but still do not have to change the LED light fixture of projective patterns at present in the industry.

The utility model content

The purpose of this utility model is to provide a kind of LED pattern lamp that can arbitrarily change projective patterns.

The utility model comprises imaging len, lamp body shell and led light source; It also has optical effect device, optical effect to drive stepper motor and pattern effect device, the optical effect device is connected with the output shaft that optical effect drives stepper motor, the pattern effect device has pattern segments and pattern disk to drive stepper motor, and pattern segments is connected with the output shaft that pattern disk drives stepper motor; Optical effect device and pattern segments are in the light path of led light source.

As further improvement of the utility model, be provided with collector lens in the lamp body shell, collector lens is in the light path of led light source.

The light that led light source of the present utility model projects is behind collector lens, and on pattern segments, then through the image-forming objective lens imaging, and pattern segments can drive stepper motor by pattern disk and changes with convergence of rays; Because led light source can not send infrared ray and ultraviolet light, so almost there is not temperature near the pattern segments, does not have ultraviolet destruction yet, pattern segments both can be made by traditional pattern segments material, also can be made by the positive negative film of cinefilm or printing.

Description of drawings

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is the schematic diagram of the utility model embodiment 1;

Fig. 2 is the schematic diagram of the utility model embodiment 2.

The specific embodiment

Referring to Fig. 1, this enforcement includes imaging len 1, lamp body shell 2 and led light source 3, wears radiating ribs 11 behind the led light source 3; It also has 4,1 optical effect of 1 optical effect device to drive stepper motor 5 and pattern effect device 6, optical effect device 4 is connected with the output shaft that optical effect drives stepper motor 5, the light that startup optical effect driving stepper motor 5 can make led light source 3 cast out produces multiple replacing effect through optical effect device 4, pattern effect device 6 has 1

pattern segments

7 and 1 pattern disk to drive stepper motor 8, and pattern segments 7 is made by cinefilm; Optical effect device 4 and pattern segments 7 are in the light path of led light source 3, and the convergence of rays that led light source 3 sends is on pattern segments 7, then through the image-forming objective lens imaging; Because led light source 3 can not send infrared ray and ultraviolet light, so almost there is not temperature rise near the pattern segments 7, also do not have ultraviolet destruction, pattern segments 7 drives stepper motor 8 output shafts with pattern disk and is connected, and starts pattern disk and drives stepper motor 8 replaceable different pattern segments.

Embodiment 2 is that with the different of embodiment 1 lamp body shell 2 is provided with collector lens 9, and collector lens 9 is in the light path of led light source 3, and pattern segments 7 is made by the positive negative film of printing.
