Novel LED lamp capable of distributing light at multiple beam angles

Abstract

The invention provides a novel LED lamp capable of distributing light at multiple beam angles. The novel LED lamp capable of distributing the light at the multiple beam angles comprises a tubular lamp body composed of a rear cover, a lamp cup, a middle lamp body ring, an inner lamp body ring and an outer lamp body ring. The lamp cup and the rear cover are connected through a heat sink. A light source plate is installed below the heat sink. The novel LED lamp capable of distributing the light at the multiple beam angles is characterized in that a plurality of LED lamp beads are distributed on the same circumference of the light source plate in an annular array mode, a rotatable adjusting face cover is arranged on the outer lamp body ring, a lens sheet is installed in the adjusting face cover, a plurality of sets of lenses with different focal lengths are arranged on the same circumference, corresponding to the LED lamp bead array, of the lens sheet, and the same set of lenses with the same focal length can coincide with the LED lamp beads through rotation of the face cover. The novel LED lamp capable of distributing the light at the multiple beam angles has the advantages of being simple in structure, convenient to adjust, adjustable in light-emitting angle, and capable of meeting the needs for a large angle, a mediate angle and a small angle. The novel LED lamp capable of distributing the light at the multiple beam angles further has the advantages that various LED lamps or LED lamps with appointed angles can be designed according to the actual needs of users, and the demand of the users are met to the maximum extent.

Description

technical field [0001] The invention relates to the technical field of LED lamp illumination control, in particular to a novel multi-beam angle light distribution LED lamp. Background technique [0002] The so-called LED lamps, as the name suggests, refer to lamps that use LED (Light-emitting Diode, light-emitting diode) technology as the main light source. LED is a solid-state semiconductor component, which uses current to flow forward to the semiconductor P-N coupling, and then the negatively charged electrons and positively charged charge carriers separated in the semiconductor are combined with each other to generate photon emission. Different types of LEDs can emit light of different wavelengths from infrared to blue, and from violet to ultraviolet. A new development in recent years is to coat blue LEDs with phosphor powder to convert blue LEDs into white LED products. This operation generally needs to be equipped with a driving circuit (LED Driver) or a power supply ...

AI Technical Summary

Problems solved by technology

However, although there are many types of LED lamps on the market at present, some focus LED lights through reflectors, and also use lenses to focus LED lights, but basically they are all fixed angles.

The beam angle emitted by this fixed-angle lamp is fixed. In some cases, when the beam to be irradiated needs to be changed, these lamps cannot meet the requirements, and the user can only replace the lamp or replace the lamp. Reflectors or lenses to meet the requirements of use, but this brings great inconvenience to users, but also requires more funds to purchase corresponding lamps, resulting in a certain waste of resources
