Regulating mechanism with return spring for LED lamp

Abstract

The invention provides a regulating mechanism with a return spring for an LED lamp. The regulating mechanism comprises a regulating ring, a movable plate, a rear base, a light source assembly, a ratchet wheel, the return spring assembled to the ratchet wheel, a rear cover and a guide ring, wherein the rear cover plate and the guide ring are assembled to the rear base; the regulating ring drives the movable plate to move up and down; the light source assembly and the ratchet wheel rotate and move up and down relative to the movable plate; when the ratchet wheel moves downwards, the return spring is compressed; the light source assembly comprises at least two light sources; the outer side wall of the ratchet wheel is provided with at least two guide teeth; the movable plate comprises a base part and a plurality of tooth parts extending from the base part; the tooth parts correspond to the guide teeth; the guide ring is provided with a perforative first hole as well as a plurality of bumps parts extending into the first hole and catching grooves positioned among the bump parts; each bump part is provided with an inclined plane; the guide teeth are positioned in the catching grooves; the guide teeth move along the inclined planes to drive the ratchet wheel and the light source assembly to rotate; and the guide teeth abut against the tooth parts for limiting rotation of the ratchet wheel. The regulating mechanism solves 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 invention relates to an adjustment mechanism of an LED lamp with a return spring, in particular to an adjustment mechanism of an LED lamp with a return spring 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 lighting. Existing LED lamps are usually a single light source or multiple light sources with fixed positions. However, in actual use, 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, and each light needs to be equipped with a reflector, which causes unnecessary waste. At the same time, the volume of the lamp is increased and the p...

Problems solved by technology

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
