No-drive LED reflector lamp

Abstract

The invention relates to a no-drive LED reflector lamp. The no-drive LED reflector lamp comprises a cup-shaped lamp body made of glass and a lamp holder which is in threaded connection with the tail end of the lamp body and an AC LED lamp, wherein a light-transmitting lens is arranged in the lamp body; a reflector layer which is used for reflecting light of the LED lamp right ahead is arranged on the inner wall of the lamp body; the LED lamp is welded onto an aluminum substrate; a pin of the LED lamp is electrically connected with the output end of a power-free LED driving chip which is welded onto the aluminum substrate; and the input end of the power-free LED driving chip is correspondingly electrically connected with a wiring terminal of the lamp holder. According to the no-drive LED reflector lamp, no driving device is needed; AC can be connected to a mains supply directly; the structure is simple; manufacture cost is low; assembly is convenient; problems occurring during a use process are reduced; and the service life is long.

Description

technical field [0001] The invention relates to the technical field of LED lighting fixtures, in particular to a driverless LED reflector lamp. Background technique [0002] As the fourth generation of lighting fixtures that are green, energy-saving, power-saving, and long-lived, LED light sources have sprung up, received wide attention, and are developing rapidly in full swing. The current LED light source is a low-voltage, high-current semiconductor device that must provide a suitable DC current to emit light normally. The technology of DC driving LED light source to emit light has become more and more mature. Since the power supply used in our daily lighting is high-voltage AC (AC100-220V), it is necessary to use step-down technology to obtain lower voltage. The commonly used ones are transformers or switching power supplies. Step down, then convert the AC to DC, and then convert it to a DC constant current source to promote the LED light source to emit light. Therefore...

Problems solved by technology

Therefore, there must be a certain space in the LED lamps of the prior art to install the driver module, resulting in the LED lamps with drivers usually having a complicated structure and relatively high manufacturing cost. Moreover, the lamp body of many existing LED lamps is Traditional aluminum and other metal materials have poor insulation performance and cannot withstand high voltage. There are also some LED lights that flicker during the light-emitting process. Long-term use of such LED lights in such an environment is likely to cause damage to the eyesight of users.
