[0038] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the drawings and embodiments.

[0039] The structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the present invention, so they have no substantial technical significance. Any modification of the structure, change of the proportion relationship or adjustment of the size, without affecting the effects and purposes that can be achieved by the present invention, should still fall within the scope of the technical content disclosed by the present utility model. At the same time, the terms such as "upper", "lower", "left", "right", "middle" and so on quoted in this specification are only for the convenience of description, and are not used to limit the scope of implementation. The change or adjustment of their relative relationship should also be regarded as the scope of implementation of the present invention without substantially changing the technical content.

[0040] In the process of outdoor short video and micro film shooting, the first requirement is that the brightness of the light can meet the fill light requirements of the scene. This is the basis, because the primary task of the fill light is to fill light. The higher the power of the lamp, the better, so that the shooting effect of the short video or micro film will not be limited. Secondly, when shooting sports scenes, the fill light is required to be portable. To achieve a panoramic lighting arrangement of a sports scene, a very professional and expensive lighting equipment is required. If it is a low-cost shooting, renting expensive lighting equipment will also exceed the budget, so a small-sized portable fill light is needed.

[0041] Example 1

[0042] The fill light of the present application has a length of no more than 150 mm and a width of no more than 75 mm, and is small in size and very easy to carry. The fill light comprises an LED light layer 1, a uniform light layer 2, a heat dissipation component 3, a front frame 4 and a rear shell 5.

[0043] like Figure 1 , Figure 2As shown, the front frame 4 and the rear housing 5 form a frame protection body, and the LED light layer 1 and the light homogenizing layer 2 are placed inside the frame. The LED light layer 1 and the light homogenizing layer 2 are placed inside the front frame 4. Among them, the front side of the LED light layer 1 is the light source surface, and a number of lamp bead groups 11 are evenly distributed on the light source surface. Each lamp bead group 11 includes at least one low-color-temperature lamp bead 111 and one high-color-temperature lamp bead 112 to meet the different color-temperature requirements in different shooting scenarios. Preferably, each lamp bead group 11 includes two low-color-temperature lamp beads 111 and two high-color-temperature lamp beads 112.

[0044] As Figure 3 , Figure 4 shown, each lamp bead group 11 uses four lamp beads, doubling the overall power of the fill light and increasing the overall brightness of the fill light to meet the needs of users. These four high- and low-color-temperature lamp beads are arranged at intervals and distributed in a cross diagonal line. The included angle of the cross diagonal line is preferably a right angle, which can achieve the best light mixing effect.

[0045] In the prior art, in order to achieve the light mixing effect, high- and low-color-temperature lamp beads are generally arranged at intervals on the lamp board. However, in some scenarios, for the need of setting the scene, when only the high-color-temperature light source is selected, since there must be a low-color-temperature light source between two high-color-temperature light sources, the brightness of the fill light is limited. If the distance between adjacent two high-color-temperature light sources is too large, it will cause uneven brightness, and the brightness at the edge of the light source is significantly lower than the brightness at the center. Similarly, when only the low-color-temperature light source is selected, there are also the same drawbacks.

[0046] In a fill light of the present application, each lamp bead group 11 includes high- and low-color-temperature lamp beads. When only the high-color-temperature light source or the low-color-temperature light source is selected, the lamp beads are not restricted by the arrangement of the lamp board 12, thus ensuring the brightness of the fill light.

[0047] To improve the light source utilization rate and make the light uniform, a light homogenizing layer 2 is correspondingly arranged on the light source surface of the LED light layer 1. The light homogenizing layer 2 includes a fly-eye lens 21 and a light homogenizing plate 22 integrally formed with the fly-eye lens 21. Each fly-eye lens 21 corresponds to a lamp bead group 11 and is used to reduce the light-emitting angle of the lamp bead group 11.

[0048] The light-emitting angle of an LED light source refers to the directivity of LED light emission, usually used to describe the scattering range of the LED light beam. The light-emitting angle is the angle at 50% luminous intensity.

[0049] As Figure 5As shown, the compound eye lens 21 is generally frustum-shaped. Among them, the large opening end 211 is closed, and a transmission surface 213 is enclosed therein. The small opening end 212 is provided with a through hole. The large opening end 211 is flush with the light homogenizing plate 22, and the small opening end 212 protrudes from the light homogenizing plate 22. The protruding end is attached to the lamp board 12 for installing the lamp bead group 11. The lamp board 12 is preferably matte. The lamp bead group 11 is located in the through hole of the small opening end 212, and the center of the lamp bead group 11 is located on the central axis of the compound eye lens 21.

[0050] More specifically, the lamp bead group 11 is electrically connected to the lamp board 12. The lamp board 12 is dimensionally adapted to the light homogenizing plate 22, and the lamp board 12 can be embedded in the frame of the light homogenizing plate 22.

[0051] The compound eye lens 21 further includes a curved surface semi-cone 214. The curved surface semi-cone 214 is surrounded by the large opening end 211 and the small opening end 212. The inner wall of the curved surface semi-cone 214 is a spherical surface, while the outer side of the transmission surface 213 is a smooth plane, and the inner side protrudes toward the small opening end 212 and is a scaly surface on the inner side. The key to the compound eye lens 21 reducing the light-emitting angle of the lamp bead group 11 lies in the combined design of the curved surface semi-cone 214 and the transmission surface 213.

[0052] According to the characteristics of LED lamp beads, their light-emitting angle is generally not less than 120°. If directly used as a fill light, it will cause the light source to be too divergent and the brightness to be not concentrated. In this application, the LED lamp bead group is used in combination with the compound eye lens 21 to improve the light energy utilization rate and the light uniformity. The lamp bead group 11 is placed inside the compound eye lens 21, and the light emitted by it is reflected and concentrated by the inner spherical surface of the curved surface semi-cone 214 and concentrated on the scaly surface on the inner side of the transmission surface 213. Several light beams are then diffused out through the scaly surface, greatly improving the light uniformity.

[0053] According to actual usage needs, the angle formed by the central axis of the compound eye lens 21 and the outer wall of the curved surface semi-cone 214 does not exceed 30°. The smaller the angle, the smaller the light-emitting angle of the lamp bead group 11 after passing through the compound eye lens, and the more concentrated the light.

[0054] When the compound eye lens 21 is used in combination with the lamp bead group 11, the light-emitting angle of the lamp bead group 11 can be reduced to 20° or 40° or 60°.

[0055] Embodiment 2

[0056] This embodiment is a further solution of Embodiment 1. When the fill light is continuously working with multiple lamp bead groups 11, a large amount of heat will be generated, and heat dissipation needs to be carried out in time, otherwise it will affect the service life of the lamp bead group 11.

[0057] In this application, as Figure 2 、 Figure 8As shown, the heat dissipation component 3 is arranged to face away from the light source surface. The heat dissipation component 3 includes a heat dissipation plate 31 and a fan 32 . The fan is used to cool the heat dissipation plate 31 .

[0058] The heat sink 31 is located between the rear housing 5 and the light board 12, and its size is comparable to that of the light board 12, and is detachably connected to the light board 12. Two fans 32 are preferably provided, symmetrically distributed at both ends of the rear housing 5. The rear housing 5 provides an external power interface for the LED lamp layer 1, including at least two interfaces, a DC power interface 53 and a Type-C power interface 54, which can adapt to different external power sources.

[0059] like Figure 6 , Figure 7 As shown, the rear housing 5 is further provided with a control unit, which includes a color temperature control unit 51 for adjusting the color temperature of the LED lamp layer 1 and a brightness control unit 52 for adjusting the brightness of the LED lamp layer 1. The LED lamp layer 1 is electrically connected to the rear housing 5.

[0060] like Figure 8 As shown, a buckle plate 56 is provided in the middle of the rear housing 5, and the adapter 55 is adapted to the buckle plate 56, and the adapter 55 is installed on the rear housing 5 through the buckle plate 56. The buckle plate 56 includes a plurality of electrode interfaces 561 and positive and negative power supply interfaces, and the adapter 55 is provided with an electrode plug-in 551 and a power supply plug-in used in conjunction with the electrode interface 561.

[0061] Among them, the positive and negative power interfaces and the power plug-in realize power supply, that is, the adapter 55 is used as a mobile power supply to power the fill light, and the electrode interface 561 and the electrode plug-in 551 are used together to realize DMX signal transmission, which is convenient for remote control of the fill light.

[0062] DMX signal transmission refers to data transmission through the DMX protocol to achieve data multiplexing and transmission. The present application can remotely achieve precise control of lighting through the electrode interface 561 and the electrode plug-in 551.

[0063] The adapter part 55 includes four adapter interfaces, namely signal input, signal output, power input and power output. Through these four adapter interfaces, several fill lights can be connected in series. The last fill light in the series can be electrically connected to the lighting control console to achieve remote lighting control. The lighting control console can be used to control all the fill lights in series, which is applied to indoor scene shooting.

[0064] A fill light of the present application can not only achieve a good light mixing effect, but also multiply the power of the fill light, and significantly improve the illumination. The lighting group 11 and the compound eye lens 21 are used in conjunction to increase the light source utilization rate and light source uniformity.

[0065] The above has schematically described the present utility model and its implementation manners. Such description is not restrictive, and only one of the implementation manners of the present utility model is shown in the drawings. The actual structure is not limited thereto. Therefore, if those of ordinary skill in the art are inspired thereby and design without creativity a structural manner and an embodiment similar to the technical solution without departing from the purpose of the creation of the present utility model, they shall fall within the protection scope of the present utility model.
