Abstract

The utility model discloses an LED light projector, including an LED light source installed on the bottom of the lamp body. A variable focus amplifying lens is installed on the top of the lamp body. The lens is obliquely or horizontally fixedly installed in the lamp body or rotatably connected in the lamp body. The LED light source is connected with an electric motor through a crank mechanism andis driven by the rotation of the electric motor to move in the lamp body. A dustproof glass is installed on top of the lens. A support for fixing the lamp body is connected on the outer side of the lamp body. The LED light projector can adjust the luminous spot size through the zoom adjustment of the amplifying lens and adjust the luminous spot in a way that the electric motor and the crank mechanism drive the LED light source to move in the lamp body.

Description

A kind of LED Projecting Lamp

Technical field

The utility model relates to lamp box, is meant a kind of LED Projecting Lamp especially.

Background technology

In the use of LED lamp box, generally adopt the led light source in the lamp body to pass through lamp body glass printing opacity, adopt this common LED lamp case as illumination or ornament lamp light time, exist the light spot shape of projection to fix, and uncontrollable problem, the long-term use makes the user feel dull.

The utility model content

In view of this, the utility model is to provide a kind of LED Projecting Lamp, to solve above-mentioned LED lamp box as illumination or ornament lamp light time, exists the light spot shape of projection to fix, and uncontrollable problem.

For addressing the above problem, the utility model provides a kind of LED Projecting Lamp, comprising: the led light source that is installed in the lamp body bottom, the lamp body top is equipped with varifocal amplifying lens, described led light source connects motor by crank mechanism, by the rotation of motor, drives led light source and moves in lamp body.

Preferably, described lens level or angle of inclination are fixedly mounted in the lamp body; Or be rotatably connected in the lamp body.

Preferably, the top of described lens also is equipped with dustproof glass.

Preferably, the described lamp body outside also is connected with the support of fixed lamp body, and the anglec of rotation is 5 to 360 degree.

LED Projecting Lamp in the utility model, but the adjusting zoom of scioptics, thus reach the effect of regulating the projection spot size, drive led light source by motor and crank mechanism and in lamp body, move, hot spot is produced regulating action.

Description of drawings

Fig. 1 is the structure chart of embodiment;

Fig. 2 is the schematic diagram of lens.

The specific embodiment

For clearly demonstrating the technical solution of the utility model, provide preferred embodiment below and be described with reference to the accompanying drawings.

Referring to Fig. 1, bottom in the LED lamp body 1 among this embodiment has led light source 2, the top of LED lamp body 1 has varifocal lens 3, as shown in Figure 2, led light source 2 is connected power supply by transformer 4 with intelligent switch 5, lens 3 can be according to needs chosen position fixed installation or the installation of inclination certain angle in lamp body 1 of spot size, also can make lens 3 is rotatably installed in the lamp body 1, the structure that zoom is regulated in lens 3 rotations, by relay lens 3, regulate the focal length of lens 3, thereby reach the needed hot spot effect of client, dustproof glass also is installed in the outside of lens 3.

In the adjustment process to the hot spot projection, focus except the rotation of scioptics 3 and to reach the adjusting to font size, also toggle can be installed in lamp body 1, toggle one end connects motor, the other end connects led light source 2, and under the rotation of motor, toggle drives led light source 2 and slides in lamp body 1, by the adjusting of led light source 2, also can produce regulating action to hot spot.

The lamp body outside also is connected with the support 6 of fixed lamp body, and the anglec of rotation is 5 to 360 degree.

LED Projecting Lamp in the utility model, but the adjusting zoom of scioptics 3, thus reach the effect of regulating the projection spot size, drive led light source 2 by motor and crank mechanism and in lamp body 1, move, hot spot is produced regulating action.

For the LED Projecting Lamp of being set forth among each embodiment of the utility model, all within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
