Description

A kind of LED solid lighting lamp

technical field

The utility model relates to a solid-state lighting lamp composed of light-emitting diodes (LEDs), in particular to an LED solid-state lighting lamp suitable for vehicle use.

Background technique

In conventional vehicle lighting, fluorescent lamps or incandescent lamps are generally used. Not only wasting energy, but also poor shock resistance, and takes up a lot of space. LED solid-state lighting is a new generation of lighting sources after incandescent lamps and fluorescent lamps. It has the characteristics of energy saving, thin, long life and so on. It is the light source for future key development.

Contents of the invention

The purpose of the utility model is to provide an LED solid-state lighting lamp whose performance is better than that of the current vehicle-mounted lighting fixtures.

The utility model LED solid lighting lamp is composed of an aluminum-based circuit board for placing light-emitting diodes, an aluminum alloy frame, an acrylic lampshade embedded in the front side of the aluminum alloy frame, and a rear cover plate arranged on the rear side of the aluminum alloy frame. The above-mentioned aluminum-based circuit board is formed with several pits at a set interval, and a light-emitting diode is arranged in each pit, and the light-emitting diodes are connected in series through wires, and the aluminum-based circuit board is placed on the aluminum-based circuit board. alloy frame.

The light-emitting diode is constructed in the following manner: the blue LED chip is pasted in the pit by sintering the silver paste laid on the bottom of the pit on the aluminum-based circuit board, and the two electrodes on the surface of the LED chip are bonded to the top of the pit. The wires are connected, and the blue LED chip is coated with a fluorescent powder with a structural formula of Y _3-xyz Gd _y ·Al ₅ O ₁₂ : _Cex , Tb _z , and a translucent semicircular plastic cap is packaged on the pit. It is a light-emitting diode that emits warm white light.

Said Y _3-xyz Gd _y · Al ₅ O ₁₂ : _Cex , Tb _z fluorescent powder is the inventor's prior invention patent application (application number is 200710055946.8, the name is the rare earth that can make the light-emitting diode emit warm white light For the fluorescent material disclosed in Fluorescent Material and Application), x in the structural formula is 0.05-0.5, y is 0.05-2, and z is 0.01-0.05.

The utility model has the following advantages: 1. The lamp can be made very thin, between 10mm-12mm, and placed in the car, it takes up little space. 2. Good heat dissipation, the aluminum alloy shell is installed on the roof of the car for easy heat dissipation. 3. LED is a solid-state lighting lamp, and the luminous material is crystal. It is shock-resistant, energy-saving, environmentally friendly, and the color temperature can be set.
