Problems solved by technology

[0003] At present, most mobile phone flash lenses can achieve light and thin effects, but the light distribution angle is relatively small, the light spot is not uniform enough, and the effect of mobile phone photography is limited when the light is insufficient. Now to achieve large-angle light distribution, only It can expand the opening diameter of the flash lens, but this will affect the appearance of the mobile phone, and at the same time limit the settings of other parts of the mobile phone. Now most mobile phone flashes have uneven light spots, which will seriously affect the photo effect

Embodiment 1

[0027] Embodiment 1, the flash lens group includes a lens group 10, a=4 LED chips 20, the lens group 10 is a flat cylinder, the lens group 10 is spliced ​​by b=4 lenses 13, and the lens 13 is a Fresnel lens , each lens 13 includes 5 complete rings; the upper side of the lens 13 is the uneven incident surface 11, the incident surface 11 is jagged from the side view, the lower side of the lens 13 is the smooth exit surface 12, and the LED chip is located at the incident surface Above the surface 11; 4 splicing edge lines 131 are formed when 4 lenses 13 are spliced; The warm and cool color temperature of each lens. 4 LED chips 20 cooperate with 4 lenses 13, which means that each LED chip 20 can use 4 lenses 13 respectively. The light emitted by the chip 20 through the lens group 10 is slightly deflected in one direction, but the light emitted by the four LED chips 20 through the lens group 10 is fused together, that is, the four slightly deflected light beams are fused together ...

Embodiment 2

[0028] Embodiment 2, on the conditions of Embodiment 1, a reflective layer is added on the exit surface 12, and the exit mode and path of the light are changed. The light emitted by the LED chip 20 enters the lens group 10 from the incident surface 11 and reaches the exit surface 12. , due to the function of the reflective layer, reflection is realized, and light is emitted from the incident surface 11 to form a large-angle light output.

[0029] Embodiment 1 is the optimal implementation among the present invention.

[0030] In the present invention, one LED chip 20 can correspond to multiple lenses 13. According to actual needs, multiple LED chips 20 are set to cooperate with multiple lenses 13, so that one LED chip 20 only corresponds to one lens 13, and the light-emitting center of the LED chip 20 and The traditional setting of the light-emitting center of the lens 13 on the same straight line, the LED chip 20 is arranged on the splicing edge line 131 between the lenses 13...

Abstract

The invention provides a flash lens assembly and relates to the field of semiconductor light emission. The flash lens assembly comprises a lens assembly and a LED chips, wherein a is larger than or equal to 1, the lens assembly is formed by splicing b lenses, and b is larger than or equal to 2; each lens comprises an incident plane on the upper side and an emergent plane on the lower side, and the LED chips are located on the incident plane side. According to the flash lens assembly, light emitted by one LED chip is controlled by two or more lenses, large-angle light distribution can be realized by combining the multiple LED chips and the multiple Fresnel lenses, formed light spots are uniform, and the lens assembly is small and thin, meets the market demand and is an excellent flash system.

Description

technical field [0001] The invention relates to the field of semiconductor lighting, and specifically discloses a flashlight lens group. Background technique [0002] LED has high luminous efficiency, low power consumption, long service life, and safety. It is an environmentally friendly and reliable light source, and is widely used in various display lighting fields. The mobile phone is an indispensable tool in modern life. It integrates various functions, one of which is the camera function. Taking pictures in an environment with insufficient light requires the cooperation of a flash. The flash of a mobile phone is generally used with an LED chip and a lens. The brightness, light distribution angle, and color temperature of the flash can all be used to evaluate the luminous effect of the flash. In addition, the size of mobile phones has been developing towards lightweight and slimming. Therefore, whether the flash is light and thin is also an indicator to measure the quali...
