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

Embodiment Construction
[0022] like Figure 1 to Figure 6 As shown, the adjustment mechanism of the LED lamp with return spring 513 in the present invention includes an adjustment ring 1, a moving plate 2 and a front seat 3 assembled to the upper end of the adjusting ring 1, a light source assembly 4 and a ratchet 5 located on the upper and lower sides of the moving plate 2 , the return spring 513 assembled to the ratchet 5, the drive circuit 31 assembled to the front seat 3, the rear seat 6 assembled to the lower end of the adjustment ring 1, the rear cover 7 and the guide ring 8 assembled to the rear seat 6.
[0023] In this embodiment, the adjusting ring 1 is a hollow cylindrical structure, the inner wall of which is provided with a first thread 10, and the moving plate 2 is provided with a second thread 201 that cooperates with the first thread 10. During the rotation of the adjusting ring 1, it drives The moving disc 2 moves up and down.
[0024] The light source assembly 4 is provided with sev...

The adjustment mechanism of the LED lamp with return spring in the present invention includes an adjustment ring, a moving plate and a back seat, a light source assembly and a ratchet, a return spring assembled to the ratchet, a rear cover plate and a guide ring assembled to the back seat, and the adjustment ring drives the moving plate Moving up and down, the light source component and the ratchet wheel rotate and move up and down relative to the moving plate, and the ratchet wheel compresses the return spring when it moves downward. The light source component includes at least two light sources, and the outer wall of the ratchet wheel is provided with at least two guide teeth. There are several tooth parts extending from the base, and the tooth parts are arranged correspondingly to the guide teeth. The guide ring is provided with a first hole through and a number of protrusions extending into the first hole and a buckle groove between the protrusions. There is an inclined surface, the guide teeth are located in the buckle groove, the guide teeth move along the inclined surface to drive the ratchet and the light source assembly to rotate, the guide teeth and the teeth resist and limit the rotation of the ratchet, which solves the problem that the light source cannot be directly rotated to switch the light source when it is placed in the optical cup and other components problem.
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...
