Abstract

The utility model provides an LED (light emitting diode) projection clock. The LED projection clock comprises a shell, wherein a projection hole is formed on the shell; a convex lens is arranged inside the projection hole; a clock, a light source, a convex lens and a reflector lens are arranged inside the shell; light of the light source is converged by the convex lens to irradiate the clock and is refracted to the convex lens inside the projection hole by the reflector lens and projected out; the LED projection clock is characterized in that: the clock is an LCD (light emitting diode) clock; the light source is an LED cold light source; the clock, the light source and the convex lens are installed on a same horizontal line in the shell; and on the same horizontal line, two another convex lenses are arranged between the clock and the light source. By adopting the structure, a projected clock image is uniform in brightness and high in definition; the LED projection clock is simple in structure, practical and energy-saving; the using effect of the LED projection clock is improved; and the practicality is improved.

Description

A kind of LED projection clock

Technical field

This reality is novel to relate to a kind of projection clock, particularly a kind of clock image projection that the LED projection forms high brightness projection clock to the objects such as metope that utilizes.

Background technology

Some projection clock comes out on the existing market; Its structure mostly is to adopt a housing to be provided with projection hole, is provided with mechanical clock, bulb source, convex lens and catoptron in the housing, passes through the irradiation mechanical clock by bulb source; Go out by convex lens, catoptron refraction projection clock image again; Though can see the image of clock, it is bright inadequately to send light source, and image effect is clear inadequately.

Summary of the invention

For addressing the above problem, the utility model provides a kind of LED projection clock, comprises housing; Housing is provided with projection hole; The projection aperture is built-in with convex lens, is provided with clock tool, light source, convex lens, catoptron in the housing, passes through convex lens focus irradiation clock tool by light source; The convex lens that are refracted to projection hole by catoptron again throw away, and it is characterized in that: described clock tool is the liquid crystal clock; Described light source is the LED cold light source; Described clock tool, light source, convex lens are mounted on the same horizontal line in the shell, are being provided with two convex lens on the same horizontal line between clock tool and the light source in addition.

Described one of which convex lens are oppositely to be installed on other two convex lens to be close to the clock tool.

Described light source is provided with aluminium alloy heat radiator and radiator fan.

Described housing is provided with the focusing support.

Described hull shape can be square body, round, heart-shaped body, prismatic body, oval body.

Adopt said structure; Cast out that the clock brightness of image is even, sharpness is high,, access the image of required size simultaneously according to the distance of irradiating object; Housing can be to fashion into square body, round, heart-shaped body, prismatic body or oval body, and the ornaments that do product high are attractive in appearance.

This use new structure is simple, energy-conservation, practical, has improved the product result of use, has improved practicality.

Description of drawings

Fig. 1 is the utility model structural principle synoptic diagram.

Be denoted as among the figure: 1 housing, 2 projection hole, 31 convex lens, 32 convex lens, 33 convex lens, 34 convex lens, 4 clock tools, 5 light sources, 6 catoptrons, 7 aluminium alloy heat radiators, 8 radiator fans, 11 focusing supports.

Embodiment

Below in conjunction with accompanying drawing, the specific embodiment of the utility model title is done further to detail, but do not constitute any restriction the utility model.

It is as shown in Figure 1,

A kind of LED projection clock; Comprise housing 1; Housing 1 is provided with projection hole 2, and projection hole is built-in with convex lens 31 for 2 mouthfuls, is provided with clock tool 4, light source 5, convex lens 32 and catoptron 6 in the housing 1; Clock tool 4, light source 5, convex lens 32 are mounted on the same horizontal line of shell interior 1, between clock tool 4 on the same horizontal line and light source 5, are provided with two

convex lens

33,34 in addition.

Convex lens 34 are oppositely to be installed on other two

convex lens

32,33 to be close to clock tool 4.

Described clock tool 4 is liquid crystal clocks, is called for short LCD; Described light source 5 is LED cold light sources.

Open light source 5, light source 5 is LED cold light sources, and brightness is high; Pass through

convex lens

32,33 high strength optically focused again on convex lens 34 and clock tool 4; Because convex lens 34 are oppositely to install with

convex lens

32,33, can play even light action, clock tool 4 whole clear being refracted on the catoptron 6; Throw away through 2 mouthfuls of built-in convex lens 31 optically focused of projection hole again, realize that brightness is even, high-resolution clock image.

Described light source 5 also is provided with aluminium alloy heat radiator 6 and dispels the heat with radiator fan 7.

Described housing 1 also is provided with focusing support 11, can access the image of required size according to the distance of irradiating object.

Described housing 1 shape is not limited to a shape, can be square body, round, heart-shaped body, prismatic body or oval body, and the ornaments that increased product are attractive in appearance.
