Detailed Description

The present invention is further illustrated by the following examples, which are intended to be illustrative, not limiting and are not intended to limit the scope of the invention.

The utility model provides a pointolite projecting lamp for museum's showpiece, as shown in fig. 1 ~ 3, the utility model discloses an innovation lies in: the LED lamp comprises an inner sleeve 5 and an outer sleeve 6, wherein a light source is arranged in the inner sleeve, one end (the lower end in the figure 1) of the inner sleeve is embedded in one end (the upper end in the figure 1) of the outer sleeve in a limiting sliding mode, at least one color compensating mirror 19 aligned with the light source is arranged at an opening at the other end (the lower end in the figure 1) of the outer sleeve, and light emitted by the light source is emitted to the outer side of the outer sleeve after passing through the color compensating.

In this embodiment, each color-compensating mirror has a color, and the color is used for enhancing some colors of light emitted by the light source when the light passes through the color-compensating mirror. In order to avoid the stimulation of light to the eyes of the viewer, the complementary color glasses have a polarization function.

The mounting structure of the color compensating mirror is as follows: the lower end cover 7 is arranged at the opening of one side end part of the cylinder body, the upper end of the lower end cover can be arranged inside the lower end of the outer sleeve in a clamping, meshing and other modes, the upper end 20 of the mounting seat 8 is arranged in the lower end 21 of the lower end cover in a clamping, meshing and other modes, the color compensating mirror is arranged in the mounting seat, and the inner check ring 18 is arranged in the opening of the mounting seat outside the color compensating mirror. When the color compensating mirror with the proper color needs to be replaced, the inner check ring only needs to be unscrewed and taken down, and then the inner check ring is installed well after the color compensating mirror is replaced, so that the lamp or the LED lamp does not need to be detached and replaced.

A retainer ring 15 is arranged in the upper end of the lower end cover positioned in the outer sleeve in a clamping, meshing and other modes, a lens 16 is tightly propped under the retainer ring, and light rays emitted by the light source are firstly processed by the lens and then are emitted out of the outer sleeve after passing through the color compensating lens.

The outer edge of the inner sleeve is provided with a scale 4 in the vertical direction, and when the outer sleeve is pulled, the vertical moving distance of the lens can be visually represented. The meaning of this distance representation is: when the light source is farthest from the lens (2 cm with the scale of the scale being the maximum) as shown in fig. 1, the corresponding light projection angle is 40 degrees; when the light source is closest to the lens (0 cm with the smallest scale of the scale) as shown in fig. 2, the corresponding projection angle is 10 degrees. Or directly marking the scale as the angle numerical value in the figure so as to be convenient for the operation of an operator.

The other end (upper end in figure 1) of the inner sleeve is provided with an upper end cover 3 which is connected with one end of a suspender 2, and the other end of the suspender is connected with a hoisting seat 1. Set up a plurality of heat dissipation through-holes 9 on the upper end cover surface, the heat that makes the light source that this structure can be better is dispelled, guarantees safe work.

The light source comprises a radiator 10 and an LED lamp 12, the radiator is embedded in the inner sleeve, and the LED lamp is arranged on the lower end face of the radiator. The radiator is provided with radiating structures which are radially and uniformly distributed and similar to fins so as to improve the radiating area. The LED lamp is of a packaged structure, namely the part of the LED lamp, which is in contact with the radiator, has good heat-conducting property, and the part emitting light is packaged by a transparent material with high light-transmitting property, as shown in figure 2, an LED lamp cover plate 14 connected with the bottom surface of the radiator is arranged below the LED lamp, and the opening on the LED lamp cover plate can enable the light emitted by the LED lamp to be emitted out and can better fix the LED lamp. The cover plate can be provided with a structure such as a clamping hook and can clamp the lamp piece of the internally packaged LED lamp on the bottom surface of the radiator, or the cover plate is provided with a thread structure and can be screwed on the structure corresponding to the bottom surface of the radiator and fix the lamp piece on the bottom surface of the radiator.

As shown in fig. 2 and 3, the inner sleeve has at least one annular groove 11 formed in an outer edge of one end of the inner sleeve located in the outer sleeve from top to bottom, a sealing ring 13 is disposed in the annular groove, and a flange or a stopper 17 for limiting the sealing ring is disposed at an opening at one end of the outer sleeve. The sealing ring realizes the functions of preventing water from entering, ash from entering and the like, and can form good damping action when the inner sleeve and the outer sleeve slide relatively, so that the relative sliding of the inner sleeve and the outer sleeve is more stable.

The utility model discloses a use method is:

1. the lamps are positioned at proper positions through the hoisting seat 1 and the suspension rod 2, so that light rays of the lamps can irradiate on an exhibit, and if the exhibit is large, a plurality of lamps are arranged at two sides, the periphery and the like above the exhibit;

2. pulling the outer sleeve to enable the emitted light to cover the whole exhibit;

3. and selecting a proper complementary color mirror to increase the color saturation of the exhibit according to the color characteristics of the exhibit.

The color characteristics of the exhibit can be determined by the following two methods:

1. the method comprises the steps of simulating a sunlight irradiation environment by adopting a proper light source, scanning a main color area of the exhibit by using a color separation instrument, extracting CMYK values of the color at the position, and selecting the color temperature and the color of a complementary color mirror according to the extracted values.

2. The method comprises the steps of simulating a sunlight irradiation environment by adopting a proper light source, generating a high-definition image of the exhibit by using a high-definition scanner or a camera, extracting CMYK values of a main color area of the exhibit by using a computer, and selecting color temperature and color of a complementary color mirror according to the extracted values.

When the color of the exhibit is single, for example: jadeite, jade article, woodenware, stoneware, etc. have even color ratio, and the inherent color is the main color.

Example 1

Exhibition: jadeite

Main color area: emerald green colour

The selection mode is as follows: first mode

The using method comprises the following steps: the lamp is arranged above the exhibit to make the light cover the surface of the exhibit

Selecting a complementary color mirror: CMYK selective anaglyph based on high definition photo extraction

The use effect is as follows: can truly restore emerald green and highlight the inherent color of emerald

The traditional light source effect: the longer use of high-brightness yellow light source reduces the effect of emerald green and glittering.

Example 2

Exhibition: porcelain bottle

The using method comprises the following steps: the four corners inside the upper end of the porcelain bottle protection frame are respectively provided with a lamp, so that light covers the surface of the porcelain bottle

Main color area: pattern of blue color

Selecting a complementary color mirror: manufacturing complementary color mirror according to CMYK extracted by color separation instrument

The use effect is as follows: can truly restore the main color of the porcelain bottle

The traditional light source effect: the display effect of the main colors is reduced by using a light source which is more blue than usual.

Table 1 shows the CMYK parameters for different types of exhibits, which are used more frequently, and the parameters in the table can be set according to the CMYK actually taken.
