Specific embodiment
With reference to the accompanying drawing, the technical solution of the utility model is described in detail.
As depicted in figs. 1 and 2, a kind of desk lamp of the utility model embodiment includes lamp cap 1, support rod 2 and pedestal 3.Branch
The both ends of strut 2 are connect with lamp cap 1 and pedestal 3 respectively.Lamp cap 1 includes the first light cover 101, the second light cover 102, light guide plate 103
With LED light strip 104；First light cover, 101 middle part and the second light cover 102 are equipped with through-hole.LED light strip 104 and the first light cover
101 are fixedly connected, and light guide plate 103 is between the first light cover 101 and the second light cover 102, and LED light strip 104 and light guide plate 103
Side it is opposite.First light cover 101 is fixedly connected with the second light cover 102.
In the desk lamp of the embodiment, it is equipped with counterweight in pedestal 3, desk lamp is avoided to topple in use.Support rod 2 is used for
Support lamp cap 1.The light that LED light strip 104 issues is entered in light guide plate 103 by the side of light guide plate 103, then by light guide plate
103 project light.It is equipped with through-hole in the middle part of first light cover, 101 middle part and the second light cover 102, light guide plate 103 is embedded in the first lamp
Between lid 101 and the second light cover 102.Light guide plate 103 projects light by front and back simultaneously.The front of light guide plate 103
It is face directed downwardly, the back side is face upward.In the lamp cap 1, light is transparent.In the prior art, whole light is all
It is projected by 103 front of light guide plate, upper plastic cover plate is usually arranged in 103 back side of light guide plate, so that light can not project.This implementation
The lamp cap 1 of example, 101 middle part of the first light cover and the second light cover middle part are equipped with through-hole, have in the front and back of light guide plate 103
Light projects, and meets lamp cap and shines up and down, and penetrating requirement, and increases the brightness of environment, is conducive to protection human eye.
To increase brightness, as preference, as shown in fig. 7, the lamp cap further includes optics site 105, optics site
105 are located at the surface of light guide plate 103.Optics site 105 is set on the surface of light guide plate 103, laser mode can be used light
Learn the surface that site is imprinted on light guide plate 103.Optics site 105 changes the direction of side incident ray, so that light guide plate 103 is formed
Shine uniform area source.Optics site 5 can be set in the front of light guide plate 3, also can be set at the back side of light guide plate 3.
When lamps and lanterns are desk lamp, it is preferred that optics site 5 is set at the back side of light guide plate 3, increases the amount of light at 3 back side of light guide plate.It leads
About 3 light pass-through of tabula rasa, the optical network point on light guide plate 3 play light reflex.
Optics site 105 is set at the back side of light guide plate 103, the light number projected from 103 front of light guide plate can be increased
Amount increases the light efficiency projected from 103 front of light guide plate.Preferably, the density of optics site 105, from 103 Center wizard of light guide plate
103 edge of tabula rasa, is gradually reduced.For example, the density of optics site 105 are as follows: unit area (CM2) dot number is 100~300
It is a, and from 103 Center wizard tabula rasa of light guide plate, 103 edge, density gradually increases.Preferably, the size of optics site 105,
From 103 Center wizard tabula rasa of light guide plate, 103 edge, it is gradually reduced.For example, the size of optics site 105 is 0.3~0.6mm, from
103 Center wizard tabula rasa of light guide plate, 103 edge, the size of optics site 105 are gradually reduced.Preferably, the depth of optics site 105
Degree, from 103 Center wizard tabula rasa of light guide plate, 103 edge, gradually increases.For example, the depth of optics site 105 be 0.03~
0.15mm, and from 103 Center wizard tabula rasa of light guide plate, 103 edge, the depth of optics site 105 gradually becomes shallower as.Rationally setting light
Density, size and the depth for learning site 105, can make light more evenly, softer.With the light guide plate luminescence technology of the prior art
It compares, the lamp cap of this preference has the function of eyeshield, comfortable.
To increase the light efficiency projected from 103 front of light guide plate, as preference, as shown in figure 8, the lamp cap further includes
Light-transmitting plate 106 and the reflective paper layer 108 of annular, the reflective paper layer 108 of annular are connected to the two sides of light guide plate 103, and light-transmitting plate 106
In reflective 108 outside of paper layer of annular, optics site 105 is between light-transmitting plate 106 and light guide plate 103.Light-transmitting plate 106 can be saturating
Penetrate light, and reflective portion light.When the back side of light guide plate 103 is arranged in light-transmitting plate 106,106 reflective portion of light-transmitting plate is from leading
The light that 103 back side of tabula rasa is projected projects some light from 103 front of light guide plate again.By be arranged light-transmitting plate 106, one
Aspect makes the light pass-through of lamp cap, on the other hand increases the light projected from 103 front of light guide plate, reduces from light guide plate 103
The light that the back side is projected.The front and back of entire light guide plate 103 is projected by light.PC material system can be used in light-transmitting plate 106
At.The reflective paper layer 108 of annular is for the light that LED light strip 104 issues to polymerize on light guide plate.
To increase heat dissipation effect, as preference, first light cover 101 is made of metal.The heating conduction of metal compared with
It is good.First light cover 101 is made using metal, heat can be distributed in time, heat is avoided to assemble inside lamp cap, is damaged
Electronic device.In the present embodiment, light source is used as using LED light strip 104.The thermal Finite that LED light strip 104 generates when working, institute
The first light cover 101 is made using metal, it not will lead to the first light cover 101 overheat and scald people.First light cover of the preference
101, in addition to cooperating with the second light cover 102, has the function of lightguide plate fixing 103, also there is heat dissipation, protect the effect of lamp cap.
In the structure, the first light cover and metal heat sink are combined into one, the first light cover makes of metal, for example, have high thermal conductivity and
High-intensitive aluminum component takes into account the LED heat dissipation double action fixed with light guide plate, meets lamps and lanterns light pass-through effect up and down.
As preference, as shown in figure 3, first light cover 101 includes ontology 1011, the bottom surface of ontology 1011, which is equipped with, to be contained
There is the positioning ring 1013 of opening 1012.Preferably, ontology 1011 and positioning ring 1013 are each made of a metal.Positioning ring 1013 is used for
Fixed LED light strip 104.Ontology 1011 and positioning ring 1013 are each made of a metal, so that the heat that LED light strip 104 generates can be with
It distributes in time.The opening 1012 of positioning ring 1013 is connected for wearing electric wire, electric wire and LED light strip 104.
As preference, the ontology 1011 is equipped with flanging 1014, and positioning ring 1013 is located at 1014 inside of flanging, fixed
Annular groove 1015 is formed between position ring 1013 and flanging 1014.The positioning to the second light cover 102 is realized using annular groove 1015
And fastening.The periphery of second light cover 102 is in annular groove 1015, it can be achieved that the positioning of the second light cover 102 and the first light cover 101
And fastening.The second light cover 102 and the first light cover 101 are being fixedly connected with using connectors such as bolts.In addition, setting flanging
1014 also increase the area of ontology 1011 Yu contacting external air.Flanging 1014 is made of metal.Flanging 1014 increases
The heat dissipation effect of ontology 1011.
To increase the fixing and heat dissipation performance that connect, as preference, as shown in figure 3, the lamp cap further includes muscle
