Technical field

The utility model relates to the technical field of lighting device, is specifically related to a kind of students ' reading eye-protecting desk lamp of uniformly light-emitting.

Background technology

At present, LED light source as new generation of green light source, its advantage comprise power consumption little, photochromic pure, brightness is high, the advantage such as environmental protection low-carbon (LC) and long service life, used in a large number in places such as government, market, school, hospital, roads.

Student generally can select desk lamp when seeing written word, and desk lamp is requisite illuminations in Modern Family.It mainly concentrates on light in one pocket, is convenient to working and learning.According to statistics, it is spend under desk lamp that China student about has 2-3 hour average every day, so for a long time under a fixing light source, see written word, if the illumination effect of desk lamp is bad, easily cause student's eye fatigue, get off for a long time and easily cause myopia, be therefore necessary that in addition structure is improved, to meet the user demand of people better.

Utility model content

In order to solve the problem, the utility model provides a kind of students ' reading eye-protecting desk lamp of uniformly light-emitting, and by being mutually obliquely installed the first chip surface and the second chip surface and being arranged on the lamp pearl of chip surface, the light that desk lamp is sent is more even.

The technical scheme that the utility model is adopted for achieving the above object is:

A kind of students ' reading eye-protecting desk lamp of uniformly light-emitting, it is characterized in that, it is provided with the lamp bar of elongate configuration, described lamp bar comprises lamp socket and lamp pearl, described lamp socket is provided with the first chip surface and the second chip surface, and described first chip surface and the second chip surface are obliquely installed mutually, and the angle of the first chip surface and the second chip surface is obtuse angle, described first chip surface and the second chip surface symmetrically structure, multiple lamp pearl is evenly arranged on the first chip surface and the second chip surface;

Described lamp socket bottom is provided with radiating fin group, and this radiating fin group and the first chip surface and the second chip surface are structure as a whole.

The lamp pearl side by side parallel of described first chip surface and the second chip surface is arranged.

The lamp pearl of described first chip surface and the second chip surface shifts to install.

Described radiating fin group comprises many fins vertically arranged, and the lower surface of described radiating fin group is concordant.

Described radiating fin group comprises the first fin, the second fin, the 3rd fin and the 4th fin that are arranged on the first chip surface bottom, and be arranged on the 5th fin of the second chip surface bottom, the 6th fin, the 7th fin and the 8th fin, described first fin and the 8th fin symmetrically structure, second fin and the 7th fin symmetrically structure, 3rd fin and the 6th fin symmetrically structure, the 4th fin and the 5th fin symmetrically structure;

Distance between described first fin and the second fin is less than the distance between the second fin and the 3rd fin, and the distance between described second fin and the 3rd fin is less than the distance between the 3rd fin and the 4th fin.

The beneficial effects of the utility model: the utility model is by arranging the first chip surface of integrative-structure, the second chip surface and radiating fin assembly, and lamp pearl is evenly arranged on the first chip surface or the second chip surface, light-emitting area due to each LED lamp bead is probably hemisphere face, the lamp bar of this structure makes the light-emitting line of the first chip surface and the second chip surface lamp pearl respectively towards both direction scattering, effectively increase the irradiating angle of lamp bar, improve the uniformity of lamp bar irradiation light.

Because radiating fin group lamp socket is structure as a whole, increase radiating effect, reduce desk lamp and to work long hours brightness decay degree; Because the length of the first fin, the second fin, the 3rd fin and the 4th fin increases successively, namely the area of dissipation of the 4th fin is maximum, therefore, distance between first fin and the second fin is minimum, distance between 3rd fin and the 4th fin is maximum, make identical area of dissipation obtain identical heat-dissipating space as far as possible, effectively strengthen radiating effect.

Below in conjunction with accompanying drawing and detailed description of the invention, the utility model is further illustrated.
