Description
Technical field
The utility model relates to optical field, relates to a kind of LED illumination light source module for road lighting or rather.
Background technology
LED illumination light source module comprises light source and reflector.Reflector refers to a kind of light reflection device that the light that can not impinge upon on work and life face that light fixture in use sends light source reflects.Reflector is a kind of reflector often used, and greatly can improve the utilization rate of the light of light fixture, Luminaire efficiency is improved greatly.The shape of reflector determines the disposal ability of reflector to the non-direct light of light source.
At the LED illumination light source module of road lighting, all there is the features such as power is high, light intensity for utilization.Because these light fixtures are from the use identity distance of light from distant, light source luminescent directly can impinge upon the just considerably less of use face, such as street lamp, 12 meters high, light source luminescent can directly impinge upon road surface less than 15% of its luminescence, its light of more than 85% will reflect by reflector, and reflector can improve the utilization rate of light.But there is following defect in the LED illumination light source module of prior art: the LED light source of LED illumination light source module all concentrates on the centre position of reflector, brightness irregularities, easy generation glare phenomenon, and the reflection angle of reflector cavity to light source is smaller, the hot spot that LED illumination light source module is formed on ground is more undesirable, look after uneven, the situation that in the middle of easily occurring, bright both sides are dark, easily produces traffic safety hidden danger.
Utility model content
The technical problems to be solved in the utility model is, provides a kind of LED illumination light source module, and this LED illumination light source module brightness uniformity, can not produce glare phenomenon, and reflector cavity is comparatively large to the reflection angle of light source, and the hot spot of formation is more satisfactory.
Technical solution of the present utility model is, provides a kind of LED illumination light source module with following structure, comprises the reflector of LED light source and bottom opening; Described LED light source comprises circuit board and LED, and described LED is provided with many, and this plurality of LEDs is distributed on described circuit board; The top of described reflector is located at by described circuit board, and described LED is located in described reflector, and described reflector is strip; Described reflector comprises antetheca, rear wall and two side; Described two side is located on the both sides of described antetheca and rear wall symmetrically; Described antetheca is inclined plane; Described rear wall and two side are the arcwall face of evagination; The LED of the middle part distribution of the circuit board that the LED of the both sides distribution of described circuit board is comparatively described is close.
After adopting above structure, LED illumination light source module of the present utility model, compared with prior art, has the following advantages:
The LED of the middle part distribution of the circuit board that the LED distributed due to the both sides of the circuit board of LED illumination light source module of the present utility model is comparatively described is close, LED does not have integrated distribution at the middle part of circuit board, the i.e. middle part of reflector, make the brightness of LED illumination light source module comparatively even like this, the phenomenon of dazzle can not be produced.Again because the two side of reflector is the arcwall face of evagination, circuit board both sides are respectively near the two side of reflector, like this, the reflection angle of two side to the LED on circuit board both sides of reflector is larger, the hot spot that the utility model LED illumination light source module is formed on ground is more satisfactory, and hot spot is rectangular, looks after more even, there will not be the situation that middle bright both sides are dark, the generation of the security incident caused by road lighting can be avoided.Again due to arcwall face that the rear wall of reflector is also evagination, the antetheca of reflector is inclined plane, the reflection angle of rear wall to the LED near it of reflector is larger, the reflection angle of antetheca to the LED near it of reflector is less, can control the width of hot spot like this, the influence of light penetrated when also avoiding LED illumination light source module to be applied on street lamp is to the life of the resident in roadside.
Improve as one of the present utility model, the top of described reflector is also provided with opening; Described circuit board is connected in described reflector open top; The open-topped length of described reflector is greater than the length of described reflector bottom opening; The open-topped width of described reflector is less than the width of described reflector bottom opening.After adopting this kind of structure, the part light of the LED near two side can can be reflected to respectively left side and the right side of LED illumination light source module by the sidewall of reflector, reflecting effect is better.
Improve as another kind of the present utility model, the longitudinal projection of some LED of the both sides of described circuit board drops on the two side of described reflector respectively.After adopting this kind of structure, the longitudinal projection LED dropped on the two side of reflector is hidden in the two side of reflector, the reflection angle of two side to the LED of this part is larger, the range of exposures along link length direction can be widened when being applied on street lamp, increase illuminating area, also make illumination more even.
Also have a kind of improvement as of the present utility model, between the top of the two side of described reflector and the two ends of circuit board, be equipped with breach.After adopting this kind of structure, LED can be dispelled the heat by breach, makes the radiating effect of light source module better.
Also have a kind of improvement as of the present utility model, the length on the top of the antetheca of described reflector is greater than the length of the bottom of the antetheca of described reflector.The sidewall of described described reflector comprises the first reflecting piece, the second reflecting piece and the 3rd reflecting piece; The first described reflecting piece, the second reflecting piece and the 3rd reflecting piece are arcwall face and join end to end and connect; The front end of the first reflecting piece is connected with the end of the antetheca of reflector, and the rear end of the 3rd reflecting piece is connected with the end of the rear wall of reflector.The 3rd described reflecting piece and the rear wall of described reflector perpendicular; The angle that the second described reflecting piece and the 3rd reflecting piece are formed is 75 °-90 °; The first described reflecting piece is triangle, and the angle that the first described reflecting piece and the second described reflecting piece are formed is 65 °-85 °.After adopting this kind of structure, the width of the irradiated area of conservative control LED illumination light source module, makes irradiated area all more even in the intensity of illumination of width and length direction further.
