Embodiment
It is understandable to enable above-mentioned purpose of the present utility model, feature and advantage to become apparent, below in conjunction with the accompanying drawings to this
The specific embodiment of utility model is described in detail.
It is fixed with reference picture 1, Fig. 2, a kind of light fixture 100 for video-photographic equipment, including lamp housing 10, lamp housing 10
Luminous component 20, the circuit (not shown) turned on luminous component 20;Luminous component 20 can light after power on circuitry,
For illuminating, the brightness of irradiated object is lifted.
Light fixture 100 also includes soft light cover 30, and soft light cover 30 is oppositely arranged with luminous component 20, is sent luminous component 20
Light can expose to the external world by soft light cover 30.Soft light cover 30 is typically made up of clear glass or transparent plastic, and in its table
Face etching groove, makes the surface irregularity of soft light cover 30.When light exposes to soft light cover 30, light is towards different directions
It is scattered, i.e., the line light that can be sent luminous component 20 is converted into soft diffused light, is shone so as to eliminate
The hot spot penetrated on object, makes captured photo, image more natural.
In the present embodiment, light fixture 100 also includes collector lens 40, and luminous component 20, soft light cover 30, collector lens 40 are successively
Set, and make the light that luminous component 20 is sent through exposing to the external world after soft light cover 30, collector lens 40 successively.
Reference picture 2, after the light that luminous component 20 is sent is scattered through soft light cover 30, light is towards each different angle
Launched, so that the waste of the light outside shooting angle can be caused.The effect of collector lens 40 is to collect light, by poly-
Light after optical lens 40 is collected in certain area.Now, if so that the region shot is located at the region that light is collected
It is interior, then the brightness of object can be effectively increased, illumination is realized;Light is additionally, since to be caught, the light outside shooting angle compared with
It is few, so as to effectively utilize light, the waste of the light outside shooting angle will not be caused.
Specifically, luminous component 20 in the present embodiment is LED lamp bead, LED lamp bead is multiple and be respectively positioned on same plane
On, light-emitting area is formed when LED lamp bead is luminous to realize illumination.In other embodiments, luminous component 20 can also be fluorescent lamp
The lamp that can be lighted Deng other.
Collector lens 40 can select convex lens, can also select Fresnel Lenses.
In the present embodiment, collector lens 40 is Fresnel Lenses.Specifically as shown in figure 3, Fresnel Lenses is general by glass
Or plastics are made, one of surface is smooth surface, and another surface is the imprinting texture face of multiple different size of concentric circles.
Light is general to be injected from smooth surface, and texture face is projected, and plays a part of collecting light.Compared to common convex lens, Fresnel Lenses
Lot of materials can be reduced, so as to reduce cost on the premise of phase same-action is played.
With continued reference to Fig. 2, light fixture 100 also includes protection eyeglass 41, and protection eyeglass 41 is fixedly installed on Fresnel Lenses tool
The first sealing cavity is formed between textured one side, and protection eyeglass 41, Fresnel Lenses.Because Fresnel Lenses has line
The one side of reason has depression and raised, in impurity such as the easy gather dusts of recess so as to influence the injection of light, reduces outgoing
The intensity of light.The effect of protection eyeglass 41 is that the recess for preventing the accumulation of impurities such as dust in Fresnel Lenses, influences
The injection of light.
In the present embodiment, anti-reflection film (not shown) is coated with the smooth surface of Fresnel Lenses, anti-reflection film is used to increase
The intensity of transmitted light in light.When light is incident to the surface of optical element, reflected light and transmitted light can be produced, is not considering to inhale
During the other factors such as receipts, scattering, the gross energy of reflected light and transmitted light is equal to the energy of incident light.
The effect of anti-reflection film is that:Redistribute the energy of reflected light and transmitted light, the result of distribution makes reflected light
Energy reduce, the increase of the energy of transmitted light.So as to increase the intensity of transmitted light, strengthen lighting effect.
In other embodiments, it can also be plated on the texture face of Fresnel Lenses and set anti-reflection film, or it is saturating in Fresnel
Plating sets anti-reflection film in the smooth surface of mirror, texture face, with the intensity of transmitted light in increasing light.
With continued reference to Fig. 1, Fig. 2, lamp housing 10 has the second sealing cavity 11, and the second sealing cavity 11, which has, passes through light
Wall, luminous component 20 is fixedly installed in the second sealing cavity 11.Second sealing cavity 11 can make luminous component 20 with
External environment, it is to avoid introduced contaminants is sticked on luminous component 20, influences illumination effect;In addition, when light fixture 100 is to clap under water
When taking the photograph offer illumination, the second sealing cavity 11 can prevent water from being contacted with luminous component 20, so as to damage luminous component 20.
In the present embodiment, the wall for enabling light pass through in the second sealing cavity 11 is soft light cover 30.That is, soft
Light shield 30 is the effect with softening light, also with sealed effect, makes luminous component 20 and external environment.
Specifically, the second sealing cavity 11 has bottom wall, the annular sidewall around bottom wall being oppositely arranged with soft light cover 30,
Annular sidewall is provided with annular groove 12, and soft light cover 30 is fixedly installed in annular groove 12.And annular groove 12 is passed through vertically
One end of annular sidewall is worn, soft light cover 30 is arranged in annular groove 12 to be glued fixed mode.
In other embodiments, the wall, which can also be one, is used for the lens of printing opacity, and it is second close that soft light cover is arranged on this
Sealing the outside of cavity is used for soft and smooth light.
With continued reference to Fig. 1, Fig. 2, light fixture 100 also includes ring support 50, and ring support 50 has first along its axial direction
Annular end 51, the second annular end 52, collector lens 40 are fixedly installed on first annular end 51, the second annular end 52
It is set in outside lamp housing 10.
Specifically, the second annular end 52 is removably set in outside lamp housing 10.That is, can be according to different feelings
Shape selects various forms of light fixtures 100, and when needing to utilize collector lens 40, the second annular end 52 is set in into lamp housing 10
Outside, light is made to pass through collector lens 40, for optically focused;When without using collector lens 40, by ring support 50 from lamp housing 10
On unload, make light after soft light cover 30, direct irradiation to the external world.
The mode that second annular end 52 is set in outside lamp housing 10 can be:Second annular end 52 is screwed onto lamp housing 10
On;Can also be:Second annular end 52 is interference fitted with lamp housing 10.
Although the utility model is disclosed as above, the utility model is not limited to this.Any those skilled in the art,
Do not depart from spirit and scope of the present utility model, can make various changes or modifications, therefore protection domain of the present utility model
It should be defined by claim limited range.
