Abstract
The utility model discloses a light distribution device, which is characterized by adopting a blade structure. A plurality of independent blades (1) are arranged at intervals and integrally connected through a rotating shaft (2). A lens (3) is formed on each blade (1) made of transparent materials. Each lens comprises a light inlet face and a light outlet face. The light distribution device regulates light outlet of light-emitting diode (LED) lamp beads through rotary motion. Required light distribution design can be achieved merely by adopting different lens modes and combinations, and heat dissipation of lamps can also be facilitated.
Description
Technical field
The utility model relates to field of illuminating lamps, relates in particular to a kind of luminous intensity distribution device.
Background technology
Led light source has that long service life, start-up time are short, energy-saving effect significantly, no ultra-violet radiation, can not bring plurality of advantages such as mercury pollution, safety in utilization height, becoming the main flow of lighting source gradually, still; Although the luminous efficiency of LED is in continuous improve, heat in the course of the work produces and still can't avoid, especially for high-power, high-density applications; These heats can badly influence the life-span and the performance of product, and existing LED light fixture mainly relies on heat radiation to dispel the heat; Heat dispersion is limited; In order to adapt to the application need that the heat radiation requirement improves constantly, existing through the device appearance that fan distributes to strengthen heat is set, Chinese patent document CN201401764Y just discloses a kind of " high-power LED lamp structure that has fan "; This high-power LED lamp structure that has fan is characterised in that: be provided with fan; Radiator is the tubular body that is provided with the hollow tube chamber, and fan is fixed in the center of radiator tail end, and what this high-power LED lamp structure that has fan adopted is the way that fan is arranged on LED lamp pearl rear end; Replacing and maintenance to fan are convenient not to the utmost; Because the rising angle of LED is less, in general lighting, need carry out homogenize to the bright dipping of LED simultaneously, existing way mainly is by measures such as lens, even light shield, LGPs the bright dipping of LED to be adjusted; Light distribution requirements with light fixture improves constantly, and needs more luminous intensity distribution means to satisfy.
The utility model content
The purpose of the utility model is to provide a kind of luminous intensity distribution device of novel structure, can realize the luminous intensity distribution design of light fixture more flexibly, and can the auxiliary lamp heat radiation.
The utility model adopts following technical scheme to realize: a kind of luminous intensity distribution device; Adopt blade construction; Have the blade of some separations to be spaced and link into an integrated entity through rotating shaft, be formed with lens on the blade of transparent material, lens package contains incidence surface and exiting surface.
The further technical scheme of the utility model is: this luminous intensity distribution device includes the lens of multiple structure.
The further technical scheme of the utility model is: the quantity of said blade is even number, and each blade evenly is spaced, and the lens arrangement on the blade of setting up in opposite directions is identical and be that axis is symmetrical set with the rotating shaft.
The further technical scheme of the utility model is: this luminous intensity distribution device also includes the fan sheet that only plays acceleration air mobilization.
This luminous intensity distribution device is adjusted the bright dipping of LED lamp pearl through rotatablely moving, and only needs to adopt different form of lens and combination can realize required luminous intensity distribution design, can also the auxiliary lamp heat radiation.
Below in conjunction with accompanying drawing and embodiment the utility model is further set forth, the protection domain of the utility model includes but are not limited to accompanying drawing and the disclosed content of embodiment.
Description of drawings
Fig. 1 is the perspective view of a specific embodiment of the utility model.。
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further to set forth.
As shown in Figure 1; This luminous intensity distribution device is a blade shape; Include eight blades 1, the lens with different structure 3 that have four groups of symmetries to set up are formed on the blade 1, and the blade 1 of eight separations evenly links into an integrated entity at interval and through rotating shaft 2; As for improving the thermal diffusivity of light fixture, the luminous intensity distribution device of present embodiment can be made radiator fan and uses because of the side incidence surface of lens has gradient.
