Description
Technical field
The present invention relates to optical field, more particularly to a kind of LED illumination light source module for road lighting.
Background technology
LED illumination light source module includes light source and reflector.Reflector refers to what light fixture was sent to light source in use
A kind of light reflection device that the light in work and life face is reflected can not be impinged upon.Reflector is be commonly used a kind of reflective
Device, can greatly improve the utilization rate of the light of light fixture, greatly improve Luminaire efficiency.The shape of reflector determines reflector pair
The disposal ability of the non-direct light of light source.
The features such as all there is high power, light intensity using the LED illumination light source module in road lighting.Due to these lamps
Have use identity distance from light from distant, light source luminescent can directly impinge upon just considerably less, such as the street lamp using face, 12 meters high,
Light source luminescent can directly impinge upon road surface less than its luminous 15%, its more than 85% light will reflect by reflector, reflective
Cup can improve the utilization rate of light.But there is following defect in the LED illumination light source module of prior art：LED illumination light source module
LED/light source all concentrates on the centre position of reflector, and brightness irregularities easily produce glare phenomenon, and reflector cavity is to light source
Reflection angle is smaller, and LED illumination light source module is less desirable in the hot spot that ground is formed, and looks after uneven, in easily occurring
Between the dark situation in bright both sides, easily produce traffic safety hidden danger.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of LED illumination light source module, and the LED illumination light source module is bright
Degree is uniform, will not produce glare phenomenon, and reflector cavity is larger to the reflection angle of light source, and the hot spot of formation is more satisfactory.
The technical solution of the present invention is to provide a kind of LED illumination light source module with following structure, including LED
The reflector of light source and bottom opening；Described LED/light source includes circuit board and LED, and described LED is provided with many, this many
LED is distributed on described circuit board；Described circuit board is located at the top of described reflector, and described LED is located at described
Reflector in, described reflector is strip；Described reflector includes antetheca, rear wall and two side；Described both sides
Wall is symmetrically on the both sides of described antetheca and rear wall；Described antetheca is inclined plane；Described rear wall and both sides
Wall is the arcwall face of evagination；The LED of the middle part distribution of the more described circuit boards of LED of the both sides distribution of described circuit board
It is close.
After above structure, LED illumination light source module of the invention, compared with prior art, with advantages below：
Due to the circuit board more described LED of the both sides distribution of the circuit board of the LED illumination light source module of the present invention
The LED of middle part distribution is close, and LED does not have integrated distribution at the middle part of the middle part of circuit board, i.e. reflector, so that LED illumination
The brightness of light source module is more uniform, will not produce the phenomenon of dazzle.Again because the two side of reflector is the arcwall face of evagination,
Circuit board both sides are respectively close to the two side of reflector, and so, the two side of reflector is to the LED's on circuit board both sides
Reflection angle is larger so that LED illumination light source module of the present invention is more satisfactory in the hot spot that ground is formed, and hot spot is rectangular, looks after
It is more uniform, be not in the dark situation in middle bright both sides, the generation of the security incident as caused by road lighting can be avoided.And due to
The rear wall of reflector is also the arcwall face of evagination, and the antetheca of reflector is inclined plane, and the rear wall of reflector is to close to its LED's
Reflection angle is larger, and the antetheca of reflector is smaller to the reflection angle close to its LED, so can control the width of hot spot,
The light projected when avoiding LED illumination light source module applied on street lamp has influence on the life of the resident in roadside.
As a modification of the present invention, opening also is provided with the top of described reflector；Described circuit board is connected to
In described reflector open top；The open-topped length of described reflector is more than the length of described reflector bottom opening
Degree；The open-topped width of described reflector is less than the width of described reflector bottom opening., can after adopting the structure
The LED of two side part light can be will be close to the side wall by reflector can be reflected to LED illumination light source mould respectively
The left side and right side of group, reflecting effect are preferable.
As another improvement of the present invention, some LED of the both sides of described circuit board longitudinal projection falls respectively
On the two side of described reflector.After adopting the structure, the LED that longitudinal projection falls on the two side of reflector is hidden
In the two side for ensconcing reflector, two side is larger to the LED of part reflection angle, and edge can be widened during applied on street lamp
The range of exposures in link length direction, increases illuminating area, also makes illumination more uniform.
As the present invention also have it is a kind of improve, between the top of two side and the two ends of circuit board of described reflector
It is all provided with jagged.After adopting the structure, LED can be radiated by breach, make the radiating effect of light source module preferable.
As the present invention also have it is a kind of improve, the length on the top of the antetheca of described reflector is more than described reflective
The length of the bottom of the antetheca of cup.The side wall of described described reflector includes the first reflecting piece, the second reflecting piece and the 3rd
Reflecting piece；Described the first reflecting piece, the second reflecting piece and the 3rd reflecting piece is that arcwall face and joining end to end connects；First is reflective
The front end of piece and the end of the antetheca of reflector are connected, and the end of the rear end of the 3rd reflecting piece and the rear wall of reflector is connected.Institute
The 3rd reflecting piece and the rear wall of described reflector stated are perpendicular；The second described reflecting piece and the folder of the 3rd reflecting piece formation
Angle is 75 ° -90 °；The first described reflecting piece is triangle, and the first described reflecting piece is formed with the second described reflecting piece
Angle be 65 ° -85 °.After adopting the structure, the width of the irradiated area of LED illumination light source module is rationally controlled, further
Make irradiated area all more uniform in the intensity of illumination of width and length direction.
