Embodiment Construction

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0023] see figure 1 , The embodiment of the present invention provides an LED for supplementary light covering a camera lens, so as to provide supplementary light with a wider range of illumination angles and uniformity for the camera lens. The camera lens includes a camera lens module (not shown), a light source 10 and a supplementary light lens group 20 mounted on the camera lens module, and the supplementary light lens group 20 and the light source 10 form the c...

Abstract

The invention provides a light supplementing lens group, which comprises a lens body and three lenses, wherein the three lenses are arranged on the lens body, the lenses are floodlight lenses, each lens comprises a light ray incident surface, a light ray emergent surface and a connecting surface, each light ray incident surface and each light ray emergent surface are respectively positioned at the opposite ends of the corresponding lens, and are connected through the corresponding connecting surface, each light ray emergent surface comprises one first emergent surface and second emergent surfaces, the first emergent surface is connected with the two second emergent surfaces, light rays pass through the light ray incident surface and are then emitted into the first emergent surface and the two second emergent surfaces, the first emergent surfaces and the two second emergent surfaces refract the light rays, and then, the light rays are emitted out. The invention also provides an image pick-up lens adopting the light supplementing lens group.

Description

technical field [0001] The invention relates to the field of lighting, in particular to a supplementary light lens group and an imaging lens using the supplementary light lens group. Background technique [0002] At present, surveillance cameras are widely used in residential buildings, roads, shopping malls, and financial offices. Each different application field requires different types of surveillance cameras. In order to meet the needs of night monitoring and monitoring in some special places, day and night surveillance cameras are developing rapidly. LEDs are installed next to the lens of day and night camera monitors for supplementary light, but the main way of these supplementary light methods currently on the market is to directly arrange LEDs next to them for supplementary light. Another way is to use LEDs and reflectors to fill in the light, but these ways do not guarantee the illuminance and uniformity. Contents of the invention [0003] In view of the above ...
