Abstract

The invention relates to the field of table lamp, discloses a table lamp lighting device, and is used for solving the problems of dazzle, low utilization ratio of luminous energy and ghosting of the existing table lamp. A reflection cover comprises a front-end wall, a top reflection curved surface and a rear-end wall; the top reflection curved surface is obliquely wrapped by the front-end wall andthe rear-end wall from the lateral side; the top reflection curved surface is a sunken curved surface; the sunken concave center is close to one side of the rear-end wall; a light-transmitting plateis located under the reflection cover and close to one side of the front-end wall; a light source module is located under the reflection cover and close to one side of the rear-end wall; a sealed optical cavity is formed by the light-transmitting plate, the reflection cover and the light source module; the light source module comprises a radiator, a light source, a polarized lens and a substrate;the radiator is provided with a groove; the substrate is arranged in the groove; the light source is distributed on the substrate in a sector shape; and, the polarized lens is arranged on the surfaceof the light source and makes the light transmitted by the light source deflecting towards the concave center of the top reflection curved surface. The table lamp lighting device is applicable to desktop work and study.

Description

technical field

[0001] The invention relates to the field of lamps, in particular to a desk lamp illuminating device. Background technique

[0002] At present, the LED desk lamps on the market often have the following problems: the first problem is the glare problem, the main reason is that the light source does not have a deep hidden light, and the light source can be seen by lowering the head of the person; the second problem is the glare problem. The problem of low energy utilization is mainly due to the large difference between the shape of the light spot and the fan shape required by the national standard; the third problem is the problem of ghosting, which is the phenomenon that multiple shadows will be superimposed when the hand is placed under the lamp. The brightness uniformity of the light-emitting surface is poor, and there are many discrete extremely bright or extremely dark areas on the light-emitting surface; the fourth problem is the problem of low uniformity,...
