Description
Technical Field
The utility model relates to the technical field of lighting fittings, specifically be a light guide plate based on desk lamp top.
Background
Chinese patent publication No. CN206757089U discloses a light guide plate for a desk lamp: however, the light guide plate has the following problems: 1) the brightness of the light source cannot be enhanced. 2) The light is too strong in the area not covered by the light guide plate.
At present, most of common table lamps are in a direct type light emitting mode, light is emitted directly through a diffusion cover or a reflector, table top illumination is achieved, the illumination range is mainly concentrated below a lamp holder, light uniformity on the table top is poor, glare is too strong due to light reflection, and comfort is low.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving above defect, provide a light guide plate based on desk lamp top.
In order to solve the technical problem, the utility model discloses a following technical scheme: the utility model provides a light guide plate based on desk lamp top, includes light source mount pad, luminance reinforcing plate and shell, and the side at the shell is installed to the light source mount pad, the reflecting plate is all installed to lateral wall in the shell and the top surface in the shell, and the lower extreme in the shell is installed to the luminance reinforcing plate, the below of luminance reinforcing plate is equipped with the glass board, and the bottom surface at the shell is installed to the glass board.
Furthermore, the brightness enhancement plate comprises a reflector plate, a light guide plate and a diffusion plate, the diffusion plate comprises a first diffusion plate and a second diffusion plate, and the reflector plate, the light guide plate, the first diffusion plate and the second diffusion plate are respectively installed from top to bottom.
Furthermore, a plurality of hexagonal bulges are arranged on the bottom surface of the glass plate. The hexagonal protrusions can assist light source diffusion.
Furthermore, a snap ring is arranged on the edge of the bottom surface of the shell. The snap ring can prevent the glass plate from accidentally falling.
The utility model has the advantages as follows:
compared with the prior art, the utility model discloses the luminance enhancement board that sets up, the luminance enhancement board can play the effect of dispersion and reinforcing to the light source that kicks into.
