Specific embodiment

The utility model is further described combined with specific embodiments below:

A kind of projection lamp with lampshade, including lamp holder 1, it is characterised in that: the lamp holder 1 is connected with for embodying projection The acrylic lamp shade 8 of content, projecting subassembly is provided in the acrylic lamp shade 8, and projecting subassembly includes substrate 2, is arranged in base Lamp bead 5 on plate is provided with projection plate rack 32 on the substrate, projects and is equipped with transparency 3, the projection on plate rack 32 Piece 3 is equipped with multiple patterns, is provided with imaging len 4 above transparency；Motor 6, the motor 6 are installed in the lamp holder 1 Shaft sequentially pass through substrate 2, projection plate rack 32 and imaging len 4, and be fixedly connected with imaging len 4 for driving imaging The effect for being projected out dynamic pattern is realized in the rotation of lens 4.

The utility model increases this displaying shell of acrylic lamp shade 8 on the basis of conventional dynamic pattern projection lamp, solution The effect of patterned display in the prior art of having determined not enough adapts to space enrironment, high to the flatness requirement of metope, and it is tired to be easy vision The problem of labor, and the effect of dynamic pattern projection is remained again, the superposition of the two effect can further improve projection lamp Decorative effect.The effect of projection is achieved in that lamp bead 5 as light source, and light passes through the imaged lens 4 again of transparency 3 Refraction is projected, and such a combination can allow product to generate the effect that a pattern projects.Spiral shell in being arranged in lamp holder 1 simultaneously Line, external screw thread is arranged in interconnecting piece 9 on acrylic lamp shade 8, and acrylic lamp shade 8 is mounted on lamp holder 1, and the pattern of projection is at sub- gram It is presented on power lampshade 8.

The substrate 2 is aluminum substrate, and aluminum substrate is a kind of metal-based copper-clad plate with good heat radiating function, general single side Plate is made of three-decker, is circuit layer (copper foil), insulating layer and metal-based layer respectively.Such as Chinese Patent Application No. 201721572790.6 disclose a kind of aluminum substrate, including copper foil layer, middle layer and aluminum layer, and the middle layer is multilayer knot Structure, the middle layer include thermal insulation layer and polyimide layer, and the thermal insulation layer is arranged alternately with polyimide layer.This The beneficial effect of utility model is: using epoxy systems and polyimide layer with Ultra-Drawing intensity in aluminum substrate, making aluminium Substrate has good thermal conductivity, anti-flammability and stronger insulation performance, meanwhile, there is bending resistance, facilitate production and processing.

The transparency 3 is film, is a kind of silver salt photographic film, is made by PC/PP/PET/PVC material.Generally Film is made of chip base and photosensitive medicine film, wherein transparent chip base is for the photosensitive medicine film of support, photosensitive medicine film is one The emulsion coating layer of kind chemical substance, they are made of some photosensitive crystal fine particles.Medicine film on the film is only in microscope It is lower just to see its particle.The image-forming principle of film is: can change after crystal particles on film are photosensitive its structure and with Other crystal combinations are at bulk, and when the light being incident upon in film medicine film is more, crystal changes and the bulk formed is also more.Institute With different light, which is radiated on film, will generate different numbers and size, shape change the crystal of structure, thus shape The image seen is also failed at one, and sizing, visible can be changed into image potential on the film by development treatment again Image.Production technology situation shows that the medicine film density on film on photosensitive more position image is big, photosensitive few position image On medicine film density with regard to small, be then fully transparent without photosensitive position.The developing time of general film is long, film Medicine film it is accordingly just thick, conversely, the medicine film of film has excellent physical mechanical property with regard to thin, excellent impact resistance is stretched Intensity, bending strength, compressive strength are high；Creep properties is small, dimensionally stable；With good heat resistance up to 125 degree and lower temperature resistance Subzero 45 degree, in wider temperature range have stable mechanical property, dimensional stability, electrical property and anti-flammability, can- It is used for a long time at 60~120 DEG C；It is in molten condition at 220-230 DEG C without sharp melting point；Since molecule chain rigidity is big, resin is molten Body viscosity is big.Water absorption rate is small, and shrinking percentage is small, and dimensional accuracy is high, good stability of the dimension, and banana is small；Belong to self-extinguishing； Light is stablized, but not ultraviolet resistance, good weatherability；Oil resistant, it is acidproof, intolerant to highly basic, oxidizing acid and amine, ketone, be dissolved in chlorination Hydro carbons and aromatic solvent easily cause to hydrolyze and crack in water for a long time.

The lamp bead 5 is 1W SMD lamp, is made of FPC circuit board, LED light, high-quality silica gel sheath pipe.Waterproof performance uses Low-voltage DC supply safe ready, luminescent color multiplicity are bright in luster；Outdoor use can resist UV aging, flavescence, resistant to high temperatures etc. Advantage, the product are widely used in contour of building lamp, the quasi- decorative lighting in public place of entertainment, ad decoration lighting lamp field.Tool There is following advantage: can arbitrarily be bent, can arbitrarily be fixed on convex-concave surface；Every 2 LED lamp constitutes primary Ioops；Compact, Various colors；With brightness height, tunable radiation emitting angle, installation, length can be customized according to requiring；Energy conservation: constant current driving surpasses Low-power consumption, electric light power is close to 100%；Environmental protection: without ultraviolet light, infrared light radiation, also without heat, no mercury leaks danger Danger；Long-lived: 5-8 ten thousand hours, be 10 times of the traditional fluorescent lamp service life or more.

The acrylic lamp shade 8 is made with acrylic material, and acrylic is a kind of organic glass, Yi Zhongkai Important thermoplastic earlier is sent out, there is the preferable transparency, chemical stability and weatherability, easy dyeing, easy processing, appearance Grace, acrylic lamp shade 8 also have some functions of acrylic material.Acrylic is in process of production, by optics Scientific addition light diffusing agent composition in grade PMMA particle, core technology are to keep diffusant uniform with the production technology of science It is distributed in plate, when light passes through plate, with being reflected when meeting for granule proliferation, reflects, the optical effects such as scattering, It is uniform and soft by crossing plate to keep light efficient, while not appearing light source again.It is very strong to natural environment adaptability, Its performance will not be made to change for a long time in solar radiation, wind and weather, anti-aging property is good, can also pacify in outdoor The heart uses；Not only it is suitble to machining but also easy thermoforming, acrylic board can dyes, surface can paints, silk-screen or vacuum coating. It is noted that harmless with people's Long Term Contact, there are also the gases generated when burning not to generate toxic gas.Acrylic 8 hardness of lampshade is 85-105HRM, non-friable, has certain anti-pressure ability.The transparent odds ratio others material of acrylic wants high Very much, very bright so under the light-illuminating at night, also it is not easy to hurt eyes.The shell of hardness, can help against Impact force and vibration will not easily fall off, in order to avoid hurt people.
