Problems solved by technology

But the biggest disadvantage of these existing spotlights is that the lamp cap and the drive circuit used by the lamp cap are integrated to form an integral lamp body, and during the use of the lamp body, the most likely to break is its drive circuit, but for general use For those who are concerned, when the driving circuit of the lamp body is damaged, the driving circuit in the lamp body cannot be replaced separately, so the entire lamp body has to be replaced, which undoubtedly increases the cost of use.
In addition, the existing spotlights are often confused or even misconnected due to the failure to correctly distinguish the positive and negative pins of the light-emitting diode LED from the positive and negative jacks between the power jacks during use. Burn out the light-emitting diodes and affect the service life of the spotlights
In addition, in order to ensure the brightness, most of the existing spotlights use relatively high-power light-emitting diodes as the light source, and the heat dissipation performance of the existing lamp body is not very good, so it often occurs that the lamp body is burned out due to internal heating. The occurrence of events such as the entire driving circuit or the light-emitting diode itself not only has potential safety hazards but also virtually increases the cost of using the product

Abstract

This invention relates to LED lamp, which comprises socket connected to power and at least one light head on bottom socket and light diode inside light head elements, polymer light cup, wherein, the said lamp head comprises light diode head and its connection socket with drive circuit set inside connected to lamp head; the said connection socket is connected to the said bottom.

Description

technical field [0001] The invention relates to a spotlight, in particular to an LED spotlight with a high-power light-emitting diode (LED) as a light source. Background technique [0002] Existing spotlights using high-power light-emitting diodes (LEDs) as light sources are widely used in various occasions because of their high luminous efficiency and energy-saving advantages, such as lighting lamps, signal lamps, decorative lamps, and the like. But the biggest disadvantage of these existing spotlights is that the lamp cap and the drive circuit used by the lamp cap are integrated to form an integral lamp body, and during the use of the lamp body, the most likely to break is its drive circuit, but for general use Or, in the case that the driving circuit of the lamp body is damaged, the driving circuit in the lamp body cannot be replaced separately, so the whole lamp body has to be replaced, which undoubtedly increases the cost of use. In addition, the existing spotlights ar...
