The utility model content:
For addressing the above problem, the purpose of this utility model is to provide a kind of white light LED for road illumination, by the light that led light source sent is carried out optical treatment, its direction of propagation is offset, thereby improve the lamp lighting utilization rate, guarantee driving at night safety.
For achieving the above object, the utility model adopts following technical scheme:
A kind of white light LED for road illumination, comprise support, described support is made of pedestal, the heating column that is positioned at the pedestal center, be provided with a groove in the middle of the described heating column, this bottom portion of groove is fixed with led chip, also is fixed with optical lens on the described support, and this optical lens bottom is connected with pedestal by holder, the top is the rectangle platform of projection, and long side one end height, an end of this rectangle platform are low.
The front of described rectangle platform is an arc, and this arc is crossed to holding level with both hands to slip over than low one by the higher end of rectangle director avris.
The length-width ratio of described rectangle platform front arc is 2:1.
Also be filled with silica gel between described support and the optical lens.
Also be filled with fluorescent material in the described heating column intermediate groove.
Described optical lens is made by PC, PMMA or silica gel material.
Described optical lens can be molded directly within the top of support.
The utility model is installed an optical lens on led light source, the light that led light source is sent by this optical lens repeatedly reflects and reflects, and finally can send along same direction, thereby make light more concentrated, avoided the waste of light, effectively raise the utilization rate of light, also eliminated the dark area of throwing light between the street lamp simultaneously, avoided the driving at night security incident.

Identifier declaration among the figure: optical lens 1, rectangle platform 101, holder 102, support 2, pedestal 201, heating column 202, led chip 203, fluorescent material 204, gold thread 205, silica gel 3.
The specific embodiment:
For setting forth thought of the present utility model and purpose, the utility model is described further below in conjunction with the drawings and specific embodiments.
The white light emitting diode that road lighting described in the utility model is used mainly is made of optical lens 1 and support 2 two parts, is described respectively below in conjunction with accompanying drawing.
As shown in Figure 1, Fig. 1 is the utility model optical lens schematic perspective view.Wherein this optical lens mainly is to have material straight forming high temperature resistant, high transmission rate by PC, PMMA, silica gel or quartz glass etc., its bottom is a holder 102, the top is the rectangle platform 101 of a projection, have fillet around this rectangle platform 101, and the long side one end height of described rectangle platform 101, an end are low, form one along the descending gradually inclined-plane of broadside side, and this inclined-plane are a level and smooth arc, the centre is a little to upper process, to reach the purpose with divergence of beam.
Level and smooth curve slope on the wherein said rectangle platform 101, the length-width ratio on this inclined-plane are 2:1, and its main purpose is by adjusting the height between lens and the illuminating source, with the half luminous flux full-shape of realizing the horizontal longitudinal axis of light source distribution curve flux near 2:1.
On this level and smooth curve slope, also be provided with anti-reflection film in addition, other parts then are provided with reflective membrane, and when light source luminescent, the light that is produced can both partly reflect by reflective membrane in this optical lens, and finally be to send by anti-reflection film curve slope place, to improve the utilization rate of light.
As shown in Figure 2, Fig. 2 is the utility model light emitting diode cross section view.It mainly is made of pedestal 201, the heating column 202 that is positioned at pedestal 201 centers, be provided with a groove in the middle of the described heating column 202, this bottom portion of groove is fixed with White-light LED chip 203, also be fixed with optical lens 1 on the described pedestal 201, the bottom of this optical lens 1 is a holder 102, and described holder 102 is buckled on the pedestal 201.
Described heating column 202 central upper portion position bottom portion of groove are fixed with White-light LED chip 203, when described White-light LED chip 203 is luminous, can produces heat, and can effectively these heats be exhaled by heating column 202, avoid defective chip.In groove, also be filled with fluorescent material 204 in addition, White-light LED chip 203 covered, and also be connected with external power source by positive and negative level gold thread respectively on the White-light LED chip 203, form current supply circuit.
As shown in Figure 3, Fig. 3 is the utility model optical lens and light emitting diode combined structural profile view.The bottom holder 103 of described optical lens 1 is buckled on the pedestal 201, and formation is combined closely, this moment, led chip 203 then was positioned under the rectangle platform 101 of optical lens 1, and had formed a cavity between rectangle platform 101 and the support, was filled with silica gel in this cavity.
