Abstract

The utility model provides an LED (light-emitting diode) backlight screen calligraphy and painting frame. LED lamps are sequentially arrayed on a grid transparent baseboard with edge strips and are scientifically combined with diffuse reflection materials so that the background of calligraphy and painting is luminous uniformly. The grid transparent baseboard with three edge strips is utilized to uniformly array the LED lamps into a light-emitting matrix with the same area with the calligraphy and painting center on the edge strips of the baseboard according to a certain point distance. A light-emitting surface is toward the direction of a backboard of the calligraphy and painting frame. Light is irradiated to a diffuse reflection board so that an LED point light source is changed into an area light source by diffuse reflection. Diffuse reflection light is subjected to secondary scattering after passing through the transparent baseboard and a light-emitting screen panel made of a scattering transparent material, so that a pure front side light source is obtained at the front side of calligraphy and painting. The calligraphy and painting is clung to a ground light-emitting screen and the effect can be rendered. The LED backlight screen calligraphy and painting frame can meet the requirement of high-grade calligraphy and painting decorations on the backlight. The product has the characteristics of low energy consumption, low heat, no radiation, uniform luminescence and the like. The LED backlight screen calligraphy and painting frame supplies a gap of the current background light source application products for preservation of cultural relics and the high-grade calligraphy and painting decorations, and has wide market prospect.

Description

LED background luminescence screen calligraphy and painting frame

Technical field

The utility model relates to the high-grade calligraphy and painting frame of a kind of slim background luminescence formula, is exactly a kind of LED background luminescence screen calligraphy and painting frame that utilizes diffuse reflection and scattering principle design particularly.

Background technology

Painting and calligraphy circle generally adopt mounting and mosaic technology to make the calligraphy and painting frame, the function that does not have background luminescence, in occasions such as Exhibition of Paintings and Calligraphy, conference and exhibition centers, light-emitting lamp rendering effect and illuminations such as many employings front shot-light, and the light fixture of high light heating is often to works, and the ancient calligraphy and painting historical relic that particularly has a reserve value causes the damage of burning of radiation and heat.Directly do background light source if adopt the common LED cold light source, luminous point causes effect not good enough can't to avoid forming one by one because of irradiation distance is too small in the painting and calligraphy front again, the ultra thin LED backlight technical products of energy-conserving and environment-protective at present, not only cost an arm and a leg, and just be applied in the specialty products of miniature dimensions, do not relate to calligraphy and painting class background brightening lighting field as yet.

Summary of the invention

The purpose of this utility model is to adapting to the characteristics in painting and calligraphy field, a kind of LED-backlit screen calligraphy and painting frame is provided, the LED lamp is arranged in order and carried out the science combination with diffuse-reflective material etc. having on the grid transparent panel base of triangle rib, make ultrathin calligraphy and painting background uniformly light-emitting, the advantage of existing energy-conserving and environment-protective, expand the LED application again, embodied the traditional calligraphy and painting characteristics that combine with modern science and technology.

The technical scheme that the utility model adopted is as follows: utilize the plastic grid transparent panel base that has the triangle rib, and the LED lamp is evenly distributed at an angle on plate base rib inclined-plane by required dot spacing, constitute and the equal-sized light emitting array of calligraphy and painting heart area.

In order to make illumination effect evenly soft, in the such scheme, transparent panel base LED lamp array light-emitting face is installed towards calligraphy and painting frame backboard direction, and light directive and plate base make it to form area source with the reflective backboard of the diffuse reflection of homalographic with the diffuse reflection of LED lamp spot light.

Diffuse behind the transparent panel base by LED, form primary scattering, again with the transparent panel base back side one determining deviation place arranged parallel with the calligraphy and painting heart with the luminescent screen panel scattering light transmissive material of homalographic such as acrylic etc., form rescattering, thereby obtain purer area source in calligraphy and painting frame front.

The calligraphy and painting works of mounting then is close to the background optical screen, highlights calligraphy and painting heart background uniformly light-emitting.

In the such scheme, the needs that can view and admire according to the calligraphy and painting art works are with various solid colors, colour mixture or the luminous and adjustable brightness of seven color changes.

The utility model passes through such scheme; make the structure of a whole set of backlight screen calligraphy and painting frame very scientific and reasonable; at the led array and the diffuse reflection reflector that will be installed on the overall plan on the transparent panel base triangle rib; scattered light panel plate makes up; energising rear drive LED lamp; obtain luminous uniform thin-type LED area source; satisfy high-grade calligraphy and painting frame and decorate the backlight demand; it is low that a whole set of products has power consumption; heat is small; radiationless; luminous all even characteristics such as with low cost; because power consumption is extremely low, can also select the solar panel power supply, to produce bigger economic results in society; filled up current historical relic's protection and high-grade calligraphy and painting frame and decorated background light source application product blank, good market prospects have been arranged.

Fig. 2 is the led array structural plan schematic diagram on the utility model transparent panel base triangle rib.

Fig. 3 is the utility model luminescent screen calligraphy and painting frame front schematic view.

Among the figure: 1, scattering material luminescent screen panel, 2, the transparent panel base of grid rib structure, 3, the triangle rib, 4, the LED lamp, 5, the diffuse reflection reflector, 6, LED lamp pin, 7, preset conductor line, 8, calligraphy and painting, 9, power supply, 10, wooden calligraphy and painting housing.

Shown in Fig. 1 embodiment: the evenly distributed LED lamp 4 in triangle rib 3 inclined-planes on the transparent panel base 2 of grid rib structure, with the pin 6 of LED lamp 4 with preset conductor line 7 and be connected, connect with power supply 9 again and constitute the light emitting array circuit, its light-emitting area keeps at a certain distance away towards diffuse reflection reflector 5, formed diffuse light transmission is by grid rib structure transparent panel base 2 and scattering material luminescent screen panel 1, form uniform surface light source, realized calligraphy and painting 8 background luminescences of mounting at wooden calligraphy and painting frame 10 fronts and luminescent screen panel 1.

Shown in Figure 2: as on the triangle rib 3 of the transparent panel base 2 of grid rib structure, to arrange the luminous matrix plane that LED lamp 4 is constituted.

The light emitting array that described LED lamp 4 grades are formed is by the reflection of diffuse reflection reflecting plate 5; and the scattering of the transparent panel base 2 of grid rib structure and luminescent screen panel 1; form luminous uniform surface light source; calligraphy and painting frame front demonstrates the calligraphy and painting background luminescence; take into account rendering effect and calligraphy and painting protecting function, have advantages of saving energy and reducing emission.
