Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, this utility model is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain this utility model, is not used to limit this utility model.
It should be noted that be referred to as " being fixed on " or " being arranged at " another element when element, it can be directly on another element or may be simultaneously present centering elements.When an element is known as " being connected to " another element, and it can be directly to another element or may be simultaneously present centering elements.
Also, it should be noted the orientation term such as left and right, upper and lower in the present embodiment, it is only relative concept or with the normal operating condition of product as reference each other, and should not be regarded as restrictive.
Such as Fig. 1～Fig. 5, this utility model embodiment provides a kind of illuminator, this illuminator at least includes light source 01, light modulation device 02 and luminous plate 03, light source 01 is for luminescence, the light source 01 of light can be distributed to surrounding for example with LED light source, halogen light source etc., light modulation device 02 is adjusted for the light sending light source 01 and exports for illumination, and luminous plate 03 is arranged at around light source 01 and is positioned at light modulation device 02 one end near light source 01.It can receive a part of light that light source 01 sends when light source 01 is luminous, and receives a part of light of light modulation device 02 reflection, such as Fig. 4, and after extinction, luminous energy is stored in inside, releases energy, such as Fig. 5 with luminous form when light source 01 is closed.
The illuminator that the present embodiment provides is arranged around at light source 01 can the energy storage when light source 01 is opened, the luminous plate 03 luminous when light source 01 is closed, when using illuminator, luminous plate 03 can accept illumination and be stored by luminous energy, illuminator because of power-off, unexpected lose, the situation such as light source is impaired can not normal luminous time, luminous plate 03 can release energy and send brighter light, improves its flying power；When illuminator is lost, stronger noctilucence is easy to user and is quickly found out illuminator；And as long as light source 01 can be luminous, luminous plate 03 gets final product energy storage, and therefore the energy of this luminous plate 03 can be continuously replenished, can luminescence for a long time, it is ensured that the noctilucent function that illuminator is lasting.
In the present embodiment, this illuminator also includes main casing 04, the power supply device 05 being connected with light source 01 it is provided with in this main casing 04, light source 01 and luminous plate 03 are installed on one end of main casing 04, light source 01 is electrically connected with power supply device 05, and light modulation device 02 can also be with one end of this main casing 04 for relying on setting.Certainly, the outer surface of this main casing 04 can also arrange the functional parts such as on and off switch, handle, holder 06, and the present embodiment repeats no more.
In the present embodiment, luminous plate 03 preferably employs transparent colloid as matrix, and mischmetal particle wherein, and rare earth material has the optical characteristics of extinction energy storage, can release energy with luminous form simultaneously, therefore can be as luminous plate 03.Certainly, the present embodiment can also use other can make luminous plate 03 by material of releasing energy of extinction energy storage luminescence.Luminous plate 03 is preferably annular, and light source 01 is arranged at the inner side hollow region of luminous plate 03.And the periphery slitless connection of the inward flange of luminous plate 03 and light source 01, and then the gap area avoiding light to be irradiated between luminous plate 03 and light source 01 causes ray waste.
Further, the light modulation device 02 in the present embodiment can be reflector, and reflector has similar bowl-shape reflecting surface, and the light that light source 01 sends is adjusted to the illuminating bundle with certain angle of divergence and brightness uniformity by its reflective surface light.This reflector has perforate, light source 01 and luminous plate 03 and is positioned at the region that perforate encloses near one end of light source 01.Light source 01 generally stretches into inside reflector, and luminous plate 03 is then at reflector bottom opening, and its surface is exposed to inside reflector, in order to accept illumination.
Further, the medial surface (i.e. reflecting surface) of this reflector can be the faceted pebble shape that faceted pebble shape, i.e. medial surface present the angled splicing successively of multiple coaxial annulus, and the angle between each annulus and the optical axis of light-distribution lens is gradually reduced along light direction.Whole medial surface can regard as a multistage broken line around one fix axle rotate a circle obtain face type, this fixing axle is the optical axis of reflector.Preferably, the optical axis of light source 01 and the optical axis coincidence of this reflector.Further, each annulus can also be connected in sequence by a circle facet shape reflecting unit, and the reflecting surface of whole reflector is latticed, and each reflecting unit has a reflection direction, and emergent ray so can be made to become more uniform.
In the present embodiment, such as Fig. 4～6, light modulation device 02 can also be light-distribution lens 021, light-distribution lens 021 is entity structure, the material higher by transmittance makes, and it also has similar bowl-shape profile, and its medial surface can reflect light, the adjustment of light is carried out, to realize uniformly going out light by the refraction of the exiting surface of light-distribution lens 021 and the reflection of medial surface.Light-distribution lens 021 is provided with the groove that can accommodate light source 01 near one end of light source 01.Due to its light transmission, luminous plate 03 is then directly mounted at bottom it, it is not necessary to extra fluting or perforate.
Having, with further reference to Fig. 6, the exiting surface 022 ecto-entad depression of light-distribution lens 021, and zone line, the light modulation circle 023 being made up of multiple annulus, light modulation circle 023 is the most protruding from its neighboring.By arranging light modulation circle 023, light source 01 imaging can be prevented, and will be close to the low-angle divergence of beam of optical axis, it is to avoid middle light intensity is too high, improves the uniformity of emergent light.
Further, the lateral surface of light-distribution lens 021 can be similar to the reflecting surface of above-mentioned reflector, presents the faceted pebble shape of multiple coaxial annulus 024 angled splicing successively, and the angle between each annulus 024 and the optical axis of light-distribution lens 021 is gradually reduced along light direction.Each annulus can also be divided into the reflecting unit of multiple facet shape further, and whole lateral surface is latticed, improves the uniformity of emergent light further.
These are only preferred embodiment of the present utility model, not in order to limit this utility model, all any amendment, equivalent or improvement etc. made within spirit of the present utility model and principle, within should be included in protection domain of the present utility model.
