Description
[technical field]
The utility model relates to a kind of light source, especially refers to a kind of LED lamp.
[background technology]
In modern illumination, the LED lamp replaces conventional light source just gradually, and the LED bulb lamp is replacing traditional bulb lamp gradually as a kind of good alternative source of light.Due to the limitation of LED light source itself, need heat dispersion preferably.Therefore thereby the light source of LED lamp need to be arranged on substrate and help heat radiation, and often needs the larger area heat sink material just can meet the requirement of heat radiation.Yet the LED light source be installed on substrate can only upwards emit beam, even added the optical elements such as transmitter that light is penetrated to the lamp holder direction, because the area of heat sink material is larger, the optical mask of printing opacity is often less, points to the major part zone of lamp holder direction and all has been arranged to heat sink material.Therefore the lighting angle of LED bulb lamp often is nothing like the lighting angle of traditional bulb lamp.
Therefore, in order to overcome above-mentioned defect, be necessary to provide a kind of improved LED lamp.

Preferably, establish heat-conducting glue between described cover of driver and described optical mask.
Preferably, the material of described optical mask is transparent heat conducting material.
Preferably, the material of described cover of driver is heat-conducting plastic.
Preferably, described support also is connected to described optical mask.
Preferably, the end face of described support and bottom surface have the optical reflection coating.
Preferably, described cover of driver comprises the outer wall that is positioned at the described LED lamp outside and the support portion of supporting described support, and support is fixed on support portion.
Preferably, described support comprises truncated cone-shaped installation portion and the annular connecting portion for connecting with cover of driver for described substrate is installed.
Compared to prior art, the utility model LED lamp has following advantage: can take into account heat dispersion and wide-angle is luminous, and simple in structure.

The cutaway view that Fig. 2 is the utility model LED lamp.
[specific embodiment]
Please refer to shown in Fig. 1 to Fig. 2, a kind of LED lamp 100, comprise optical mask 1, cover of driver 2, light source 6, the substrate 8 of light source 6 and the support 5 that supports the substrate 8 with light source 6 be installed.Substrate 8 is fixed in support 5, and support 5 is connected with cover of driver 2, and optical mask 1 is connected with cover of driver 2.In the present embodiment, establish heat-conducting glue (not shown) between cover of driver 2 and optical mask 1, support 5 is established heat-conducting glue with between cover of driver 2, and optical mask 1 is fixed in cover of driver 2 by heat-conducting glue, and support 5 is fixed in cover of driver 2 by heat-conducting glue.In other embodiment, optical mask 1 also can be fixed in cover of driver 2 by additive method, and support 5 also can be fixed in cover of driver 2 by other means.
Cover of driver 2 comprises the outer wall 22 that is positioned at LED lamp 100 outsides and the support portion 21 of supporting bracket 5.Support 5 is fixed on support portion 21.
The material of optical mask 1 is transparent heat conducting material.The thermal conductivity factor of Heat Conduction Material is two kinds of 6-8W/m*K, 20-30W/m*K.The material of cover of driver 2 is heat-conducting plastic.Optical mask 1 also can heat conduction, and optical mask 1 can extend toward lamp holder 3 to greatest extent like this.In the utility model, light source 6 produces heat, and the heat that light source 6 produces first conducts to substrate 8, then by substrate 8, conducts to support 5, and support 5 conducts to cover of driver 2 by heat.Cover of driver 2 sheds a heat part by air, another part conducts to optical mask 1, and conducts in air by optical mask.Optical mask 1 has the effect of printing opacity on the one hand, also has on the one hand the effect of heat conduction, get final product like this so that optical mask 1 extends to lamp holder 3 directions as far as possible, thereby the lighting angle of LED lamp 100 is larger.Simultaneously, due to cover of driver 2 heat radiations that a part is used the heat radiation plastics to make, optical mask 1 heat radiation that a part utilizes Heat Conduction Material to make, make the heat dispersion of LED lamp 100 better.In the present embodiment, substrate 8 is pasted on support 5 by heat-conducting glue (not shown), and substrate 8 can be good at heat is conducted to support 5 like this.
In the present embodiment, support 5 does not connect optical mask 1, in other embodiments, if wish that the heat dispersion of LED lamp 1 is better, support 5 also can be connected to optical mask 1.Heat can be directly conducted to respectively optical mask 1 and cover of driver 2 by support 5 like this.
In the present embodiment, support 5 is made by metal material, in other embodiment, also can be made by materials such as potteries.Support 5 roughly is several fonts perpendicular to the 21 cross section, support portion of cover of driver 2.Support 5 comprises for the truncated cone-shaped installation portion 54 of installation base plate 8 and the annular connecting portion 55 for connecting with cover of driver 2.Support 5 edges are the direction projection of lamp holder 3 dorsad, thereby forms relatively near the bottom surface 51 of lamp holder 3, the relative end face 52 away from lamp holder 3 and connection end face 52 and 51 side, bottom surface 53.Side 53 is positioned at the lateral surface of truncated cone-shaped installation portion 54, and end face 52 is positioned at the end face of truncated cone-shaped installation portion 54, and bottom surface 51 is positioned at connecting portion 55.Bottom surface 51 and end face 52 are towards same direction.Better for the optical property of LED lamp 100, end face 52 and the bottom surface 51 of support 5 have the optical reflection coating, thereby it is luminous more to be conducive to LED lamp 100 wide-angles.The cross section of support 5 is several fonts, and light source 6 and light source substrate 8 are fixed in support side 53.Side 53 has certain gradient, and side 53 has a certain degree with end face 52 shapes, and this angle is between 60 degree to 80 degree.
The utility model LED lamp 100 can take into account heat dispersion and wide-angle is luminous, and simple in structure.Optical mask 1 not only has good light transmission but also can dispel the heat, thereby makes optical mask 1 to extend to lamp holder 3 directions as far as possible, enlarges the lighting angle of LED lamp 100, can not worry heat dissipation problem again simultaneously.
