Abstract

The utility model discloses a lighting device which comprises a light guide pillar, an optical film and a luminous module. The optical film is surrounded on the periphery of the light guide pillar at intervals. The ratio between the diameter of the optical film and the diameter of the light guide pillar is between 2 and 3. The luminous module is arranged on one side of the light guide pillar. Rays cast from the light guide pillar is reflected by the optical film to form an unreal amplified luminous effect. In addition, the optical film which surrounds the periphery of the light guide pillar can prevent the light guide pillar from being scratched because of collisions. Experiments prove that when the ratio between the diameter of the optical film and the diameter of the light guide pillar is between 2 and 3, the best imaging effect can be obtained.

Background technology

At present, lighting device become in people's daily life indispensable necessity.Along with the universalness of lighting device, simple illumination functions can't satisfy modern's demand.Therefore, more and more lighting devices that have illumination and aesthetic function concurrently just are developed.Please refer to Fig. 1, Fig. 1 is the sketch map of the lighting device 1 of prior art.As shown in Figure 1, lighting device 1 comprises leaded light post 10, light emitting module 12 and base 14.Leaded light post 10 is arranged on the base 14.Light emitting module 12 is arranged in the base and is positioned at a side of leaded light post 10.The light that light emitting module 12 is sent can be through projecting around the leaded light post 10.The light-emitting area of lighting device 1 is that the diameter D by leaded light post 10 decides.Therefore, if desire increases the light-emitting area of lighting device 1, just must increase the diameter D of leaded light post 10.Yet because the increase multiplying power of the production cost of lighting device 1 can be much larger than the increase multiplying power of the diameter D of leaded light post 10, the diameter D that therefore increases leaded light post 10 does not meet the production cost demand.In addition, leaded light post 10 generally is to be processed by plastic material, and the leaded light post 10 that exposes is prone to touched and scratch, thereby influences visual aesthetic.

The utility model content

The utility model technical problem to be solved is: in order to remedy the deficiency of prior art, a kind of lighting device is provided, it is surrounded on the blooming compartment of terrain around the leaded light post, to address the above problem.

The lighting device of the utility model adopts following technical scheme:

Said lighting device comprises leaded light post, blooming and light emitting module.The blooming compartment of terrain is surrounded on around the leaded light post, and the ratio of the diameter of the diameter of blooming and leaded light post is between 2 and 3.Light emitting module is arranged at a side of leaded light post.

The haze value of said blooming is less than 20%.

The reflectivity of said blooming is between 10% and 50%.

The focal length of said blooming equals the twice of the distance between said leaded light post and the said blooming.

The material of said blooming is Merlon, polymethyl methacrylate or brightness enhancement film.

Said light emitting module is a light emitting diode.

Said light emitting module is made up of a plurality of light emitting diodes, and the light color that each light emitting diode sent is different.

Have a plurality of scattering mediums in the said leaded light post.

Said a plurality of scattering medium is a bubble.

Therefore; According to technique scheme; The lighting device of the utility model has advantage and beneficial effect at least: the utility model is surrounded on around the leaded light post with the blooming compartment of terrain, and the light that projects through the leaded light post is reflected by blooming, thereby forms the illumination effect of illusory amplification.In addition, the compartment of terrain is surrounded on leaded light post blooming on every side and can prevents that the leaded light post from being touched and scratch.When experiment showed, that ratio when the diameter of the diameter of blooming and leaded light post is between 2 and 3, can obtain best imaging effect.

The specific embodiment

Please refer to Fig. 2 to Fig. 5; Fig. 2 is the stereogram of the lighting device 3 of the utility model one embodiment; Fig. 3 is the vertical view of leaded light post 30 and blooming 32 among Fig. 2; Fig. 4 is the side view of leaded light post 30, blooming 32 and light emitting module 34 among Fig. 2, and Fig. 5 is leaded light post 30, the blooming 32 and the profile of light emitting module 34 along the X-X line among Fig. 4.As shown in Figure 2, lighting device 3 comprises leaded light post 30, blooming 32, light emitting module 34, radiating seat 36 and lamp holder 38.Leaded light post 30 can by polymethyl methacrylate (Polymethylmethacrylate, PMMA), Merlon (Polycarbonate, PC) or other similar material process.Blooming 32 can by Merlon, polymethyl methacrylate, brightness enhancement film (Brightness Enhancement Film, BEF) or other similar material process.Light emitting module 34 can be single color LED (Light Emitting Diode; LED); Perhaps light emitting module 34 can be made up of a plurality of light emitting diodes, and the light color that each light emitting diode sent different (for example, light emitting module 34 can be made up of the redgreenblue light emitting diode).

Blooming 32 compartment of terrains are surrounded on around the leaded light post 30.Light emitting module 34 is arranged in the radiating seat 36 and is positioned at a side of leaded light post 30.The heat that radiating seat 36 is produced in the time of can operating light emitting module 34 is dispelled the heat.Lamp holder 38 is fixed in the bottom of radiating seat 36.Lighting device 3 can be arranged on the lamp socket (not shown) through lamp holder 38.In practical application, be provided with electric wire (not shown) and drive circuit board in the lamp holder 38, with conductivity to the light emitting module 34 that lamp socket is provided, thereby light emitting module 34 is emitted beam.The light that self-luminous module 34 is sent gets into leaded light post 30, again through being projected to blooming 32 around the leaded light post 30.In this embodiment, blooming 32 is partly to penetrate/the half reflection film, that is to say, and the penetrable blooming 32 of part light, part light can be by blooming 32 reflections.In addition, owing to blooming 32 compartment of terrains are surrounded on around the leaded light post 30, so blooming 32 also has the imaging function of similar lens.Just can between blooming 32 and leaded light post 30, be formed the amplification virtual image by the light of blooming 32 reflections, thereby form the illumination effect of illusory amplification, make lighting device 3 have illumination and aesthetic function concurrently.

When experiment showed, that ratio as the diameter D2 of the diameter D1 of blooming 32 and leaded light post 30 is between 2 and 3 (just, 2≤D1/D2≤3), can obtain best imaging effect.Preferably, when the focal length of blooming 32 equal between leaded light post 30 and the blooming 32 apart from the twice of d the time, can make the virtual image just fill up the space between leaded light post 30 and blooming 32.In addition, when the haze value of blooming 32 less than 20%, and the reflectivity of blooming 32 can further be promoted imaging effect between 10% and 50% the time.

As shown in Figure 5, can have a plurality of scattering mediums 300 in the leaded light post 30, so that light is scattered leaded light post 30 from different directions.Scattering medium 300 can be the bubble that in forming process, produced of leaded light post 30 or be embedded in the particle in the leaded light post 30, looks practical application and decides.

The preferred embodiment that the above is merely the utility model is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
