Fig. 1 is the perspective view of an embodiment of this utility model rational LED of a kind of luminous intensity distribution。
The realization of this utility model purpose, functional characteristics and advantage will in conjunction with the embodiments, are described further with reference to accompanying drawing。
Detailed description of the invention
Should be appreciated that specific embodiment described herein is only in order to explain this utility model, be not used to limit this utility model。
With reference to Fig. 1, one embodiment of the rational LED of a kind of luminous intensity distribution of the present utility model is proposed, include bulb socket structure, holder structure 200 from the bottom to top successively, be fixed on the light source mounting post of holder structure 200 upper end, be fixedly arranged on the LED light source structure 400 of light source mounting post lateral wall, be connected and fixed on holder structure 200 upper end and LED light source structure 400 is covered the diffuser 500 that sets, also include the driving device electrically connected with LED light source structure 400。
Light source mounting post is divided into upper part 301, end portion。
The lateral wall of upper part 301 is set to towards tilted inclined plane, LED light source structure 400 pacify ringwise be fixed in inclined plane and towards obliquely downward irradiate such that it is able to be irradiated to the region below LED, being covered with the reflection shield 600 that light can be reflected away outside end portion, reflection shield 600 is the bowl-shape of back-off。
Light source mounting post is formed in one structure being made up of heat-conducting metal。
LED light source structure 400 includes the substrate that some annulars are laid in inclined plane, the some LED lamp bead being laid on substrate。
This utility model changes traditional light-configuration mode, some LED lamp bead annular equably is laid in inclined plane, LED lamp bead is made to irradiate towards obliquely downward respectively in all directions, and it is covered with the reflection shield 600 bowl-shape in back-off to increase the irradiating angle of light at the end portion of light source mounting post, it is provided with reflector layer at reflection shield 600 outer surface, light is irradiated on reflection shield 600 and reflection irradiation below surrounding and LED all occurs, so, the light part that LED lamp bead of the present utility model sends shines directly into the region of lower section, some reflexes to the lower zone of surrounding or LED by reflection shield 600, light has been carried out rational distribution, major part light illuminates the zone of action of people all down, whole LED is made to define the luminous body that a three-dimensional light irradiates towards surrounding and lower section, luminous intensity distribution is reasonable, light efficiency is high, reach the effect of energy-conserving and environment-protective。
