5results about How to "Solve uneven lighting" patented technology

The invention relates to a light control method and system based on a holographic interactive projection technology, and the method comprises the steps: projection region recognition, user interaction detection, light parameter calculation and light real-time regulation and control, the projection region recognition, scanning of a target region through a holographic projection device and a depth induction sensor, and generation of a three-dimensional space model of an environment; a motion capture device and a deep learning algorithm are used for carrying out real-time recognition on gestures or motions of a user, interaction intentions and priority ranking are generated, a holographic projection device is used for generating a three-dimensional environment model, the motion capture device recognizes the intentions of the user, and an illumination optimization model is used for calculating regulation and control parameters; and the output of the light equipment is dynamically adjusted, so that high-precision and intelligent light control is realized, and the problems that a traditional light control method is insufficient in environment perception capability, lacks a user interaction mode, is limited in flexibility and adaptability of light regulation and control, and lacks a multi-module cooperative working mechanism are solved.

The lamp comprises a light source, a reflector, a first inner mask, a second inner mask and an outer mask, the first inner mask, the second inner mask and the outer mask are sequentially arranged in the light emitting direction of the light source, and the light source is located between the reflector and the first inner mask. According to the lamp, the multiple light uniformizing masks are arranged, so that the irradiation problem of uniform light emitting on a large light emitting surface can be solved, the light efficiency is improved, and the light loss is reduced. The invention further discloses a vehicle.

The lifting type eye protection intelligent classroom illuminating lamp comprises a shell and a lamp wick installed at the front end of the shell, connecting ropes are arranged on the upper side, close to the left side and the right side, of the shell, fixing blocks are arranged on the upper sides of the two connecting ropes, a motor is arranged between the two fixing blocks, and the motor is connected with the shell. The motor is electrically connected with an external power source, the outer walls of the left end and the right end of the motor are fixedly connected with driving rods penetrating through the interiors of the fixing blocks, the driving rods are fixedly connected with connecting ropes, the outer wall of the front end of the motor is fixedly connected with a receiver, and heat is discharged from heat dissipation holes by installing a blocking cover and the heat dissipation holes; and dust accumulated on the shell can be blocked by the blocking cover, so that the situation that heat dissipation of the shell is affected by dust accumulation is avoided, the temperature of the lamp wick during long-time work is reduced, and the situation that the temperature is too high and consequently the lamp wick is damaged is avoided.

The utility model discloses a kind of uniform light components and lamps, the uniform light component is fixed in another surface of lamp stand and located above LED lamp plate, the uniform light component includes first reflecting film, light guide column, second reflecting film, semi-permeable piece and diffusion film pasted in turn from bottom to top;The positive light emission of the LED lamp plate is guided by light guide column, converts point light source into area light source and first light uniformity;By first reflecting film and second reflecting film reflection, again by semi-permeable piece, second light uniformity is carried out after emission diffuse light, diffusion film is third light uniformity after carrying out to uniform emission. Three light uniformity processing solve the problem that there is uneven light in the projection of the existing LED lamp in bright area directly below.
