Description

Technical Field

[0001] The present disclosure relates to the technical field of optical lenses, and in particular to a structure and a light source module for improving soft light. Background Art

[0002] The light source of the electronic device flash is a semiconductor solid-state light-emitting device. In the semiconductor, excess energy is released through the recombination of carriers, causing photon emission, directly emitting red, yellow, blue, and green light. On this basis, by using the principle of three primary colors and adding fluorescent powder, it can emit light of any color. The light source of the flash is set in the electronic device for lighting.

[0003] The light source of the flash of an electronic device has the function of supplementary light, thereby making the electronic device more effective. However, since the light of the flash light source irradiates along a straight line, the illumination brightness is too high, making the light source of the flash light more glaring, and directly looking at the light source of the flash light for a long time may cause eye damage.

[0004] For example, a low-power mobile phone flash disclosed in the comparative document CN201821272514.2 includes a base, a circular reflective cup is fixedly provided on the top of the base, openings are symmetrically provided on both sides of the circular reflective cup, a circular lamp holder is fixedly connected to the top of the circular reflective cup, four LED lamps are evenly fixed inside the circular lamp holder, sealed wiring holders are symmetrically fixed on both sides of the bottom of the circular lamp holder, a conductive substrate is fixed inside the sealed wiring holder, the positive and negative poles of the four LED lamps are respectively connected to the two conductive substrates through two wires, and one end of the two wires is respectively inserted through the bottom of the two sealed wiring holders, and a camera is fixedly connected to the middle of the top of the base. This solution can provide better shooting effects with lower power consumption, but it cannot solve the problem that the brightness of the flash is too high, making the light source of the flash more dazzling.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present disclosure belongs. The terms used in the description of the present disclosure herein are only for the purpose of describing specific embodiments and are not intended to limit the present disclosure. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0032] To better understand the technical solutions and beneficial effects of the present disclosure, the present disclosure will be further described in detail below with specific embodiments:

[0033] As Figures 1 to 6 shown, the structure 10 for improving soft light in an embodiment of the present disclosure includes a light-emitting device 100, a condenser lens 200, a reflection lens 300, and a light-emitting lens 400. The light-emitting device 100 is used to generate light. The condenser lens 200 is provided with a condenser groove 201, and a condenser reflection surface 210 is formed on the surface of the condenser groove 201. The condenser reflection surface 210 is used to converge light so that the scattered light is reflected and emitted forward. The light-emitting device 100 is installed at the bottom of the condenser groove 201.

[0034] Furthermore, the reflective lens 300 is arranged above the focusing lens 200, and the reflective lens 300 includes a reflecting portion 310 and a transparent portion 320. A free reflecting surface 311 is formed on the surface of the reflecting portion 310, and the free reflecting surface 311 is used to change the direction of light. The free reflecting surface 311 is arranged above the focusing reflecting surface 210, and the transparent portion 320 is connected to the outer periphery of the reflective portion 310; the light output lens 400 is covered on the side of the reflective lens 300 away from the focusing lens 200, and the light output lens 400 includes a first light shielding portion 410, an annular light output portion 420 and a second light shielding portion 430. The annular light output portion 420 is connected to the outer edge of the first light shielding portion 410, and the second light shielding portion 430 is connected to the outer edge of the annular light output portion 420, and the annular light output portion 420 is correspondingly arranged above the transparent portion 320.

[0035] In this embodiment, the light emitting device 100 generates light. When the light is scattered in all directions, the scattered light is incident on the focusing reflecting surface 210. The focusing reflecting surface 210 converges and scatters the light and emits it toward the light-transmitting portion 320, so that the scattered light enters the annular light-emitting portion 420 from the light-transmitting portion 320; the direct light is emitted forward, and the direct light is incident on the free reflecting surface 311 to generate diffuse reflection, so that light at different positions forms light at different angles after being reflected by the free reflecting surface 311, and the light at different angles is then incident on the focusing reflecting surface 210. The focusing reflecting surface 210 converges light at different angles and emits it toward the light-transmitting portion 320, so that light at different angles enters the annular light-emitting portion 420 from the light-transmitting portion 320, and the light is emitted from all sides of the annular light-emitting portion 420.

[0036] In the above-mentioned structure 10 for improving soft light, when the light emitting device 100 generates direct light, the direct light generates diffuse reflection at the position of the free reflection surface 311 to form light of different angles. The light of different angles first enters the focusing reflection surface 210, and then the light of different angles converges from the focusing reflection surface 210 to the light-transmitting portion 320 to emit light. The light reflected by the free reflection surface 311 reduces the amount of direct light emitted, and increases the amount of light emitted from the light-transmitting portion 320 at different angles, so that the soft light effect of the light emitted from the annular light-emitting portion 420 is better, thereby reducing the damage to the eyes caused by light.

[0037] like Figure 1 and Figure 3As shown, in one embodiment, the free reflection surface 311 includes an arc convex surface 3111 and an arc concave surface 3112, the arc convex surface 3111 is arranged at the center of the incident reflection portion 310, the incident arc convex surface 3111 is arranged above the incident light-collecting reflection surface 210, the arc concave surface 3112 is connected to the outer periphery of the arc convex surface 3111, and the outer periphery of the arc concave surface 3112 is connected to the light-transmitting portion 320. In this embodiment, the arc concave surface 3112 is formed in the circumference of the arc convex surface 3111, so that after the direct light enters the arc concave surface 3112, the direct light is emitted to the surroundings with the arc convex surface 3111 as the center, and the emitted light enters the light-collecting reflection surface 210, thereby being reflected again and converged on the light-transmitting portion 320.

[0038] like Figure 2 As shown, in one embodiment, the light emitting lens 400 is provided with an annular groove 401, and the annular light emitting portion 420 is disposed in the annular groove 401. In this embodiment, the annular light emitting portion 420 is disposed in the annular groove 401, so that the surface of the annular light emitting portion 420 is lower than the position of the light shielding portion 420, thereby reducing the collision between the annular light emitting portion 420 and the outside world, thereby reducing the probability of the annular light emitting portion 420 being scratched.

[0039] like Figure 1 As shown, in one embodiment, the radius of the light focusing groove 201 is greater than the radius of the light-transmitting portion 320. In this embodiment, when the radius of the light focusing groove 201 is small, part of the light falls outside the light focusing groove 201, resulting in part of the light being unable to be reflected into the light-transmitting portion 320, and the light passing through the light-transmitting portion 320 is reduced. The radius of the light focusing groove 201 is greater than the radius of the light-transmitting portion 320, so that most of the light can be reflected through the light focusing groove 201, and the reflected light enters the light-transmitting portion 320, thereby maintaining the brightness of the light emitted by the annular light-emitting portion 420.

[0040] like Figure 1 As shown, in one embodiment, the radius of the inner ring of the annular light emitting portion 420 is greater than the radius of the reflecting portion 310. In this embodiment, when the inner ring of the annular light emitting portion 420 is smaller than the radius of the reflecting portion 310, the reflecting portion 310 will block the annular light emitting portion 420. The radius of the inner ring of the annular light emitting portion 420 is greater than the reflecting portion 310, which prevents the reflecting portion 310 from blocking the annular light emitting portion 420, thereby allowing light to be uniformly emitted from the annular light emitting portion 420 to the surroundings.

[0041] like Figure 2As shown, in one embodiment, the inner wall of the light-focusing groove 201 includes a bottom reflective plane 211 and a conical reflective concave surface 212, the conical reflective concave surface 212 is connected to the outer periphery of the bottom reflective plane 211, and the light-emitting device 100 is installed at the center of the bottom reflective plane 211. In this embodiment, the conical reflective concave surface 212 allows light to converge, and the light-emitting device 100 is installed at the center of the reflective plane. The light converged by the conical reflective concave surface 212 is uniform, and the light passes through the light-transmitting portion 320 uniformly, so that the light is uniformly emitted from the annular light-emitting portion 420 to the surroundings.

[0042] like Figure 2 As shown, in one embodiment, the bottom reflective plane 211 is further provided with a receiving groove 2101, and the light emitting device 100 is installed in the receiving groove 2101. In this embodiment, when the light emitting device 100 is installed in the receiving groove 2101, the light emitting surface of the light emitting device 100 is parallel to the bottom reflective plane 211, making the structure more compact, thereby saving installation space.

[0043] like Figure 1 As shown, in one embodiment, the first light shielding portion 410 further includes a first light shielding layer 411 and a first shell layer 412, the first light shielding layer 411 covers the surface of the first shell layer 412, and the annular light emitting portion 420 is connected to the outer edge of the first shell layer 412; the second light shielding portion 430 further includes a second light shielding layer 431 and a second shell layer 432, the second light shielding layer 431 covers the surface of the second shell layer 432, and the second shell layer 432 is connected to the outer edge of the annular light emitting portion 420. In this embodiment, the first light shielding layer 411 and the second light shielding layer 431 are formed by spraying light shielding paint on the first shell layer 412 and the second shell layer 432, respectively, and the light is blocked by the first light shielding layer 411 and the second light shielding layer 431, so that the light can only be emitted through the annular light emitting portion 420, thereby controlling the light to be emitted from all sides of the annular light emitting portion 420.

[0044] like Figure 3 As shown, in one embodiment, a positioning groove 402 is provided on one side of the light emitting lens 400 adjacent to the reflective lens 300. In this embodiment, the light emitting lens 400 needs to be installed on the housing, and the housing can be provided with an adapted positioning groove 402 corresponding to the contour, so that the light emitting lens 400 is limitedly installed at the corresponding position, thereby reducing the shaking of the light emitting lens 400 on the housing.

[0045] The present application also provides a light source module, including the structure 10 for improving soft light in any of the above embodiments. In this embodiment, the diffuse reflection of the light of the light emitting device 100 after being reflected by the free reflection surface 311 and the focusing reflection surface 210 increases, and the light forms light of different angles after being reflected by the free reflection surface 311, and the light of different angles is emitted from the four sides of the annular light emitting portion 420, so that the light emitted by the light source module is softer.

[0046] Compared with the prior art, the present invention has at least the following advantages:

[0047] In the above-mentioned structure 10 for improving soft light, when the light emitting device 100 generates direct light, the direct light generates diffuse reflection at the position of the free reflection surface 311 to form light of different angles. The light of different angles first enters the focusing reflection surface 210, and then the light of different angles converges from the focusing reflection surface 210 to the light-transmitting portion 320 to emit light. The light reflected by the free reflection surface 311 reduces the amount of direct light emitted, and increases the amount of light emitted from the light-transmitting portion 320 at different angles, so that the soft light effect of the light emitted from the annular light-emitting portion 420 is better, thereby reducing the damage to the eyes caused by light.

[0048] The above-mentioned embodiments only express several implementation methods of the present disclosure, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the disclosed patent. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present disclosure, and these all belong to the protection scope of the present disclosure. Therefore, the protection scope of the disclosed patent shall be subject to the attached claims.
