Embodiment Construction

[0036] The present invention will be further described below in conjunction with accompanying drawing.

[0037] like figure 1 As shown, the two major parts of the lamp body 1 and the handle 2 of the dimmable color LED lamp of the present invention are connected by a multi-position adjustable knob 6 . There are three LED lamp groups 10 in the lamp cap 8 , the lamp cap 9 on the lamp cap 8 is screwed with the lamp body 1 , and the lamp cap 9 fastens the lamp group 10 through the glass sheet 11 .

[0038] The lamp body 1 is conical, with a slot-shaped cooling structure 16 at its tail, and a water-proof and dust-proof circular hole-shaped power interface 5 on the side. The handle 2 includes an adjustable drive module 3 , a light color adjustment module 7 and a rechargeable battery 4 . There is a hollow channel in the center of the adjustable knob 6, which accommodates the connecting wires between the lamp body 1 and the inner modules of the handle 2.

[0039] like figure 2 As ...

Abstract

The invention discloses an LED lamp with the light color adjusting function. The LED lamp comprises a lamp holder, a lamp body and a handle, wherein three LED lamp sets are arranged in the lamp holder and each LED lamp set comprises a high color temperature LED string and a low color temperature LED string. An adjustable drive module, a light color adjusting module and a rechargeable battery are arranged in the handle, and the handle is connected with the lamp body via a multi-shift adjustable rotary knob. The light color adjusting module comprises two brightness adjusting rotary knobs and three dial switches which work together to control the lamp to emit lights with high color temperature, low color temperature and moderate color temperature between the high and low color temperatures, as a result, the adjustment of the color temperature, the spectrum and the brightness can be realized. According to LED lamp disclosed by the invention, the light control signal generation circuit has a simple structure, the linearity of the operation signal is good, the lamp is widely applicable for indoor purposes and outdoor occasions without external power sources and in need of extensive light adjustment of multiple lamps, and further, the modular structure of the lamp brings convenience in installation, maintenance and light emitting angle adjustment.

Description

technical field [0001] The invention belongs to the field of LED lighting, and in particular relates to a dimmable color LED lamp. Background technique [0002] Since the LED light source is a cold light source, has no heat radiation, does not cause any damage to the eyes and skin, and does not contain lead, mercury and other polluting elements, it realizes true green, so LED lamps are widely used in lighting facilities. In many occasions of lighting applications, it is necessary to use different color temperature light sources according to the situation or work and life requirements. For example, light with high color temperature is easier to focus people's attention, while light with low color temperature is more warm and warm. [0003] When traditional light sources were used in the past, because the same lamp can only emit one kind of light, it is difficult to meet this requirement or only multiple lamps can be used to switch and change light. Nowadays, after using LED ...
