LED down lamp

Abstract

The invention discloses an LED down lamp. The LED down lamp comprises an LED (light-emitting diode) down lamp body, a light-transmitting plate, a driving circuit board, an LED lamp and a built-in driving power supply circuit, wherein the light-transmitting plate is installed on the light outlet of the LED down lamp body; the LED driving circuit board is installed in the accommodating space between the LED down lamp body and the light-transmitting plate; raw materials of the light-transmitting plate (in parts by weight) include a polymer resin, an ABS resin, a fire-resistant master batch, a curing agent, aluminum hydroxide, an accelerator, a nanometer powder, a polyester mill base (yellow), a polyester mill base (red), vinyl benzene, titanium dioxide, a compound lubricant and an anti-foaming agent. The LED down lamp is characterized in that the built-in driving power supply circuit is arranged on the LED driving circuit board, so that the LED light source part and the power supply driving part are integrally designed, the LED down lamp cannot be affected on light effect, is relatively simple and beautiful, and is relatively convenient to install and use by an user; the light-transmitting plate for decorating the LED is good in light-transmitting effect, beautiful in appearance and convenient to manufacture, and thus the light-transmitting plate can be widely applied to irregular decorative lighting, lamp posts, and diaphanous cylinder lighting ceilings.

Description

technical field [0001] The invention relates to an LED lamp, in particular to an LED downlight. Background technique [0002] LED is a green energy-saving light source with high light conversion efficiency and has been widely used for lighting. Due to the low voltage of LED itself, it must be converted into low-voltage drive by an external switching power supply when used in combination with mains power. Usually, it is reflected in downlight products. It is a very inconvenient and unattractive state, and increases the weight of the downlight itself, which has potential safety risks, and also involves various increases in packaging costs, transportation costs, and installation costs. [0003] Various light-transmitting plates are installed on the existing LED lamps. This light-transmitting plate includes acrylic, polycarbonate, and artificial stone plates made of unsaturated polyester resin. This artificial stone The thickness of the similar plate is 5mm, and the length and ...

[0003] Various light-transmitting plates are installed on the existing LED lamps. This light-transmitting plate includes acrylic, polycarbonate, and artificial stone plates made of unsaturated polyester resin. This artificial stone The thickness of the similar plate is 5mm, and the length and width are about 1-2m. This kind of artificial stone can be installed with a background light on its back, and the light can penetrate from the back. The production of this light-transmitting plate was first inspired by natural hibiscus stone , because this natural stone has been used to make a variety of stone lamps, and the light can come out from the inside of the stone, but this kind of stone is very expensive and cannot heat the curved garden.
