Abstract

The invention relates to the technical field of LED lamps, and discloses an LED lamp with a variable light angle and a dimming method. The lamp includes a light source board, a lens, an LED driver and a drive controller. There are at least two LED lamp bead groups on the light source board, and each LED lamp bead group includes at least one LED lamp bead. There is a lens on the side, and the light angle of the lens on different LED bead groups is different. The drive controller includes a microprocessor, the microprocessor includes a storage module and a control module, the storage module is used to store the duty cycle data of different LED lamp bead groups under different light angles, the control module is used to query the data of the storage module, and output all The duty cycle control signal of the light angle is required. The invention can adjust the light emitting angle, has a large dimming range, has no mechanical movement of the lens and the LED lamp bead, has a simple structure, saves the original movement space, effectively reduces the volume and weight, is convenient to process, and has high reliability.

Description

technical field [0001] The invention relates to the technical field of LED lamps, in particular to an LED lamp with variable light angle and a dimming method. Background technique [0002] With the continuous reform and development of science and technology in our country, various energy-saving products are widely put into the market for use. The use of these energy-saving products can save the consumption of functional resources, and at the same time, the use effect is better. For example: LED is one of the current The new energy-saving light source has been applied to various occasions related to lighting, such as car lights, stage lights, indoor lights, street lights, etc. Compared with the traditional ones, the light source has a long service life and electro-optic, gradually replacing the traditional incandescent lamps. Not only low energy consumption, but also better light intensity and higher utilization rate. [0003] Based on different application scenarios, users ...
