Description

Novel lighting effect desk lamp

Technical Field

The utility model relates to the field of lighting technology, especially, relate to a desk lamp of novel light efficiency of utensil.

Background

The desk lamp, generally indicate the illumination lamps and lanterns that have the base of putting the usefulness on the desk, the light-emitting mode of desk lamp has straight following formula light-emitting, indirect formula light-emitting, wherein indirect formula light-emitting includes reflective light-emitting and leaded light formula light-emitting, but the desk lamp of current leaded light formula is the change of light-emitting mode more, do not have fine utilization convex lens principle to take place the spotlight effect to the light of different frequencies and form the colorful light-emitting of light that special spotlight effect and different refractions presented, make the desk lamp only satisfy in the effect of illumination function in the function, make the desk lamp function singleness, can not satisfy people and have more higher requirements to the functionality of desk lamp.

Convex lens: the edge is thin, the middle is thick, at least one surface is made into a spherical surface, and the two surfaces can also be made into spherical surfaces. The imaging principle of the convex lens is an optical law. In optics, an image which is formed by converging actual light rays and can be presented on a light screen is called a real image; the image which is formed by converging reverse extension lines of light rays and cannot be presented on the light screen is called a virtual image, the convex lens is used for refraction imaging, and the imaged image can be an inverted and reduced real image; inverted, equi-sized real images; inverted, magnified real image; erect, magnified virtual images. The light rays are converged.

Newton first made a well-known prism experiment, which documented in the literature: in early 1666, I made a triangular glass prism that was used to study light color. Therefore, the room is painted with the ink, and a small hole is formed in the window to allow a proper amount of sunlight to enter. I put the prism at the light entrance again, make the refracted light can be to the opposite wall, when I see the bright intense photochromic that this produces for the first time, make I feel very big joyful. "experimental design for newtons: through this experiment, a colored spot was obtained on the wall, the arrangement of colors being red, orange, yellow, green, cyan, blue, violet.

The refraction of light refers to a phenomenon that when light obliquely enters another medium from one medium, the propagation direction is changed, so that the light is deflected at the junction of different media. Belonging to the refraction phenomenon of light. The refractive index is also frequency dependent, called dispersion, and the same medium has different refractive indexes for light of different frequencies; in media transparent to visible light, the refractive index often increases with decreasing wavelength, i.e., the refractive index for red light is the smallest and the refractive index for violet light is the largest.
