Low-voltage LED spotlight

Abstract

The invention discloses a low-voltage LED spotlight. The low-voltage LED spotlight comprises a plastic base, a heat radiator and a lens, and the plastic base is connected with a power source. The low-voltage LED spotlight is provided with a remote controller, the plastic base is connected with the rear end of the heat radiator in a fastened manner, a plate electrode is mounted in the plastic base, the heat radiator with two ends communicated is hemispherical, a recessed hemispherical surface of the heat radiator is provided with a reflective layer, the front end of the heat radiator is connected with the lens in a fastened manner, an aluminum substrate covers the lens and is connected with the plate electrode and fixed in the heat radiator through fastening screws, and a plurality of beads are arranged on the aluminum substrate. The heat radiator is provided with two annular venting grooves, service life of an electrolytic capacitor, the main part of the power source, is prolonged, and a WIFI (wireless fidelity) wireless signal remote control device is added, so that a cellphone or remote controller with a WIFI transceiver can be used for remote controlling. The low-voltage LED spotlight is almost maintenance-free, soft in light and pure in spectrum, eyesight protection and health of workers are benefited, and luminance effect is equivalent to that of halogen lamps.

Description

technical field [0001] The invention relates to an LED lamp, in particular to a low-voltage LED spotlight. Background technique [0002] In the prior art, LED spotlights are spotlights that use light-emitting diodes as light sources. Traditional spotlights mostly use halogen lamps, which have low luminous efficiency, relatively high power consumption, elevated ambient temperature and short service life. At present, there are more and more lamps and lanterns made of LEDs as light sources, among which the most favorable ones are LED spotlights, because compared with other LED lamps, the price of LED spotlights is more advantageous. [0003] LED spotlights, due to the use of solid light-emitting diodes as the light source, the service life mainly depends on the solid LED light source and the drive heat dissipation part. At present, the life of the LED light source can reach more than 100,000 hours. With the continuous development of LED technology and the improvement of applica...

AI Technical Summary

Problems solved by technology

[0004] At present, because the base of the LED spotlight is fastened by threads, when the heat is generated, the fastening screws cannot dissipate heat, causing the product to loosen, resulting in poor performance

In order to achieve high power, the general LED spotlights mainly place multiple LED lamp beads separately, and the lens is made into 3x1W, 4x1W, etc. This method will make the brightness of the lamp beads uneven after passing through the lens, and there will be multiple focal lights. , the color reproduction of the object is not good, and the color is distorted

[0005] After searching, there is no technology in the prior art that uses wireless remote control technology to change the luminous intensity of LED spotlights
