CN103032812A - Manufacturing method of LED (Light-Emitting Diode) lantern - Google Patents

Abstract

The invention relates to a manufacturing method of an LED (Light-Emitting Diode) lantern. The manufacturing method comprises the following steps of: preparing 10.5kg of solid-state low-density polyethylene, putting into a flour mill for milling for 10 minutes, and sieving with a 40-mesh sieve; putting processed low-density polyethylene and a dyeing pigment into a high-speed color mixer in the ratio of 25:1, and running for 15 minutes; loading a prepared material into a die cavity, and thermally running in a furnace body for 30 minutes, wherein the temperature of a hot furnace is 300 DEG C; and extracting from the furnace body, cooling for 20 minutes, extracting from a die, and manually trimming to obtain a finished product. A low-density polyethylene shell is arranged, and an LED lamp is arranged inside the shell, so that the appearance and internal illuminating performance of the conventional product are improved, the appearance level is raised, and the illumination effect has the characteristics of freeness from light spots, prevention of fading, long service life and the like; and meanwhile, the production process of the entire lantern is simple, and the processing efficiency is increased conveniently.

Description

A kind of preparation method of LED lantern

Technical field

The present invention relates to a kind of decorative lamp, relate in particular to a kind of preparation method of LED lantern.

Background technology

Lantern also is a kind of Celebrating decorative thing as a kind of conventional lamp of the Chinese nation.Along with the development in epoch, can different pattern or literal be set at lantern, also can be used as advertisement function, have good light decorative effect, to be made by cloth art and ticker tape but a lot of lantern is many, moulding is outmoded, technique is backward, fragile.Present product, mainly adopt two kinds of preparation methods: one, luminous lantern shell generally adopt bamboo or metal to make skeleton, at the red silk of skeleton outer wrap or red rainproof organic film, bulb etc. are set in skeleton; This luminous lantern is typical and traditional product, the lantern product that is present people's Festival celebration Festival, heighten atmosphere, at once does something for the occasion with the most use, but exist the defectives such as technology content is lower, appearance effect is not luxurious, class is not high, lighting effects are relatively poor, simultaneously, this product passes through the damage of very easily fading afterwards that drenches with rain of exposing to the weather, under many circumstances can be owing to volume to be installed greatly inconvenience, the incandescent lamp bulb that adopts is shorter service life, can not satisfy long-time user demand; Its two, adopt metal material processing to become lantern frames, then use plastic neon lamp on the warp of lantern frames, but the method is more coarse, be not suitable for transportation and packing, be only suitable for local the use.They are three years old, some luminous lanterns that also have generally adopt the PET plastic casing, in-built LED lamp, but this product is because the PET material is thinner, more fragile or break, the guest uses very inconvenient, can also see the LED lamp of the inside when light is light at night, seem just not attractive in appearance, of paramount importance defective is complex manufacturing in the middle of production process, production capacity is very low, and cost compare is high.In numerous products, of paramount importance defective is, traditional product much adopts the acrylic shell, its service time weak point, non-uniform light, fade, have hot spot.

Summary of the invention

For above defective, the invention provides a kind of illumination effect evenly, without luminous point, can not occur fading, sound construction be difficult for broken, production efficiency is high, reduce cost, the preparation method of the LED lantern that is conducive to increase the service life, thereby solve the technical problem of existing product.

For achieving the above object, the present invention is by the following technical solutions:

A kind of preparation method of LED lantern mainly is comprised of following steps:

(1) prepares solid-state low density polyethylene (LDPE) 10.5kg;

Ground 10 minutes when (2) putting into flour mill, after 40 eye mesh screens;

(3) low density polyethylene (LDPE) that processes and dyeing pigment are put into the high speed color mixing machine according to 25: 1 ratio, move 15 minutes;

(4) material that will modulate is put in the mold cavity, and heat run is 30 minutes in body of heater, and hot furnace temperature is 300 ℃;

(5) take out from body of heater, cooled off again 20 minutes, in mould, take out, by artificial deburring to finished product, at the enclosure interior LED lamp of packing into.

The beneficial effect of the preparation method of LED lantern of the present invention is: the method is by arranging the low density polyethylene (LDPE) shell body and at the enclosure interior LED lamp of packing into, traditional product outward appearance and internal illumination performance have been improved, be conducive to promote the outward appearance class and make its illumination effect even, characteristics such as reaching without hot spot, can not occur fading, service time is long; Simultaneously, the production process of whole lantern is simple, is convenient to improve working (machining) efficiency.

The specific embodiment

The preparation method of the described LED lantern of the embodiment of the invention mainly is comprised of following steps:

(1) prepares solid-state low density polyethylene (LDPE) 10.5kg;

Ground 10 minutes when (2) putting into flour mill, after 40 eye mesh screens;

(3) low density polyethylene (LDPE) that processes and dyeing pigment are put into the high speed color mixing machine according to 25: 1 ratio, move 15 minutes;

(4) material that will modulate is put in the mold cavity, and heat run is 30 minutes in body of heater, and hot furnace temperature is 300 ℃;

(5) take out from body of heater, cooled off again 20 minutes, in mould, take out, by artificial deburring to finished product.

Above embodiment is the more preferably specific embodiment a kind of of the present invention, the common variation that those skilled in the art carry out in the technical program scope and replace and should be included in protection scope of the present invention.

Claims (1)

1. the preparation method of a LED lantern is characterized in that, mainly is comprised of following steps:

(1) prepares solid-state low density polyethylene (LDPE) 10.5kg;

Ground 10 minutes when (2) putting into flour mill, after 40 eye mesh screens;

(3) low density polyethylene (LDPE) that processes and dyeing pigment are put into the high speed color mixing machine according to 25: 1 ratio, move 15 minutes;

(4) material that will modulate is put in the mold cavity, and heat run is 30 minutes in body of heater, and hot furnace temperature is 300 ℃;
