Built-in driven LED (light-emitting diode) down lamp

Abstract

The invention discloses a built-in driven LED (light-emitting diode) down lamp. The built-in driven LED down lamp comprises an LED down lamp body, a light transmission plate, a driving circuit board, an LED lamp and a built-in driving power circuit; the light transmission plate is installed on a light outlet of the LED down lamp body, and the LED driving circuit board is installed in a holding space between the LED down lamp body and the light transmission plate; the light transmission plate comprises the following raw materials in part by weight: transparent resin, polycarbonate, curing agent, aluminum hydroxide, accelerant, talcum powder, polyester mill base yellow, polyester mill base red, styrene, titanium dioxide, submicron powder, high efficiency slushing agent and antifoaming agent. Through the built-in driven power circuit arranged on the LED driving circuit board, the LED light source part and the power driving part are integrally designed, and the light effect is not influenced; the built-in driven LED down lamp is more concise and beautiful, and more convenient to install and use of a user; moreover, the light transmission plate for the LED decoration is good in light transmitting effect, beautiful and elegant in appearance, and convenient to manufacture; the built-in driven LED down lamp is widely applied to irregular light fixtures, lamp pillars, light-transmission column lighting ceiling, and others.

Description

technical field [0001] The invention relates to an LED lamp, in particular to an LED downlight with a built-in drive. 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 5m...

[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 unsightly state, and increases the weight of the downlight itself, which has potential safety risks, and also involves a variety of cost 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 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.
