Regulating mechanism of LED lamp

Abstract

The invention relates to a regulating mechanism of an LED lamp. The regulating mechanism comprises a regulating ring, a movable plate, a rear base, a light source assembly, a ratchet wheel, a staggering plate and a guide ring, wherein the movable plate and the rear base are separately assembled to the upper end and the lower end of the regulating ring; the light source assembly and the ratchet wheel are positioned at the upper side and the lower side of the movable plate; the staggering plate and the guide ring are assembled to the rear base; the light source assembly comprises at least two light sources; the outer side wall of the ratchet wheel is provided with at least two side-surface oblique teeth; the side-surface oblique teeth are disconnected, and limiting slots are formed between the side-surface oblique teeth; the ratchet wheel further comprises bottom-surface oblique teeth downwards extending from the side-surface oblique teeth; the guide ring is positioned above the staggering plate; the guide ring is provided with a perforative first hole and a plurality of buckles extending into the first hole; each buckle is provided with an inclined plane; the staggering plate is provided with a perforative second hole and a plurality of tooth parts positioned around the second hole; the buckles are positioned in the limiting slots; and the regulating ring drives the movable plate, the light source assembly and the ratchet wheel to move up and down for switching the light sources, so that the problem that the light sources cannot be switched in a rotary manner due to the fact that the light sources are arranged in components such as a light cup in a sleeved manner is solved.

Description

【Technical Field】 [0001] The present invention relates to an adjustment mechanism of an LED lamp, in particular to an adjustment mechanism of an LED lamp with multiple light sources. 【Background technique】 [0002] LED has the advantages of long life, high luminous efficiency, no radiation, impact resistance, low power consumption, etc., and belongs to energy-saving green environmental protection lighting. Therefore, LED lights with LED as light source are welcomed by the majority of users. The existing LED lights are usually a single light source or multiple light sources with fixed positions. However, in the actual use process, there are the following problems: some light sources with multiple light colors need to be switched in daily use, so that single-light-source lamps cannot meet the requirements, and multi-light-source lamps are required. The existing multi-light source fixed mode cannot use the same reflector. It is necessary to install a reflector for a single lamp, wh...

However, in the actual use process, there are the following problems: some light sources with multiple light colors need to be switched in daily use, so that single light source lamps cannot meet the requirements, and multi-light source lamps are required

The existing multi-light source fixed mode cannot use the same reflector. It is necessary to install a reflector for each lamp, which causes unnecessary waste. At the same time, the volume of the lamp becomes larger and the portability is lost, or the same lens is used for multiple light sources. It will cause severe eccentricity of the light spot, a serious drop in the utilization rate of light, seriously affect the use, and cannot meet the needs of users
