Description

Technical Field

[0001] The utility model relates to the technical field of stage lamps, and more specifically to a lighting device with both display and coloring functions. Background Art

[0002] In stage design or architectural lighting, wash lamps are an indispensable part. They are mainly responsible for projecting light spots with uniform color and brightness. By switching different colors, they render the environment, highlighting key points, strengthening details and setting the atmosphere. For example, warm colors can create a passionate, tense or pleasant atmosphere, while cool colors bring a calm or mysterious atmosphere.

[0003] In order to present a light spot with a large coverage area and uniform color brightness, the light-emitting surface of a wash lamp is usually designed to be larger. There are many types of wash lamps, such as wash lamps with flat lamp heads. Most of these wash lamps on the market are used in combination with display screens to increase simple display effects, but the two functions are difficult to be compatible on the same light-emitting surface at the same time. The display screen can only be set on the back of the wash light source and one can be selected. When it is necessary to switch the wash or display function, the drive module is used to drive the lamp head to rotate relative to the support frame so that the working light-emitting surface faces the target plane. Frequent rotation of the vertical rotation axis not only increases the operating steps, but also takes a certain amount of time to switch, and smooth switching cannot be achieved. The audience can clearly feel the switching gap, and the experience is poor. Utility Model Content

[0004] The utility model is to overcome at least one defect of the prior art described above and provide a lighting device with both display and dyeing functions. By setting a display screen with high light transmittance, the problem that stage dyeing lamps are difficult to have both dyeing and display functions on the same light emitting surface is solved.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: a lighting device with both display and dyeing functions, including a light board, and a plurality of light-emitting units arranged on the light board, and also including a display screen. Along the emission direction of the light emitted by the light-emitting unit, the display screen is located in front of the light board, and a plurality of pixel units are arranged on the display screen. Each of the pixel units includes a pixel grid for emitting pixels to form a picture and at least one transparent grid for the light generated by the light-emitting unit to pass through.

[0006] By arranging the transparent grid on the display screen, the light emitted by the light-emitting unit can freely pass through the transparent grid. When the light-emitting unit on the light board is working, the light emitted passes through the display screen and projects a light spot with uniform color and brightness to the target plane, thereby achieving the effect of dyeing, wall washing or stroboscopic. When the user needs a display effect, the pixel grids on the display screen cooperate with each other to display the required picture, so that the lighting device can realize the functions of dyeing and display on the same light-emitting surface, and the two functions can be used separately or in combination according to the design. When switching the two functions, it is only necessary to simply switch through the circuit without rotating the lamp head, which greatly shortens the transition time and reduces the visual time difference of the audience.

[0007] Furthermore, the pixel grid includes three primary color blocks for emitting three primary colors. The three primary color blocks can display different colors as needed, and then form different pictures by combining several blocks of the pixel grid to achieve the display function.

[0008] Furthermore, the three primary color blocks in the pixel grid are arranged in sequence in a horizontal direction, and the transparent grid is arranged parallel to the length direction of the pixel grid, so that the shape of the pixel grid is regular and easy to arrange.

[0009] Furthermore, the pixel grid also includes a white block for emitting white light. By adding the white block, the brightness of the mixed color light of the pixel grid is improved, and its light transmittance is increased.

[0010] Furthermore, the three primary color blocks and the white block are spliced ​​into a rectangle, and the transparent grid is arranged close to any side of the rectangle, so that the distance between the three primary color blocks and the white block is closer, and the color mixing effect is better.

[0011] Furthermore, the area of ​​the transparent grid accounts for 1 / 2 to 2 / 3 of the total area of ​​the pixel unit, providing enough light-transmitting area for the light emitted by the light-emitting unit to pass through, thereby ensuring the light transmittance of the display screen.

[0012] Furthermore, a plurality of the pixel units on the display screen are spliced ​​together, and the pixel units can be closely arranged to accommodate a greater number of the pixel units, so that the image displayed on the display screen is more delicate.

[0013] Furthermore, the light emitting unit is an LED lamp bead, which has a simple installation structure and is energy-saving and environmentally friendly.

[0014] Furthermore, the display screen is an OLED display screen. The OLED display screen does not require a backlight source, and when the display screen is not working, it can act as a nearly transparent light-emitting lens; and the OLED display screen has better image quality, and has the advantages of short response time, high energy-saving efficiency, and more flexible operation.

[0015] Furthermore, it also includes a control circuit, which includes an MCU control unit, and a dyeing module and a display module which are independently controlled by the MCU control unit, the dyeing module is electrically connected to the light board, and the display module is electrically connected to the display screen. The independent control method is easier to operate and less prone to errors.

[0016] Furthermore, it also includes a flat lamp head and a support frame for pivotally connecting the lamp head, the display screen forms a light-emitting surface of the lamp head, and the lamp head can rotate at multiple angles around the support frame to achieve multi-angle rendering.
