Integrated down lamp

Abstract

The invention discloses an integrated down lamp, which comprises a cold cathode fluorescent lamp, a lamp tube fixing seat, a reflecting cup and a surface ring, wherein the surface ring and the reflecting cup are arranged together through a rivet; the cold cathode fluorescent lamp is fixed on the lamp tube fixing seat in a gluing mode and is connected with an output end of an inverter in the lamp tube fixing seat through a high-voltage-resistant conductor; a self-locking wiring clamp in a self-locking fast-insertion junction box is connected with an input end of the inverter; the lamp tube fixing seat, the cold cathode fluorescent lamp and the inverter are integrated and are arranged on a reflecting barrel in the gluing mode; and the integrated down lamp is clamped on a mounting part through spring fasteners. By the integrated down lamp, a lamp holder, a lamp tube and the inverter have an integrated structure and are integrally arranged on the reflecting barrel, the defects of the traditional down lamp are overcome, and the integrated down lamp has the advantages of small size, low cost, long service life, low light attenuation, zero stroboflash, eyesight protection and convenience in installation, can be turned on / off frequently, and is particularly suitable for places such as marketplaces, hotels, households, meeting places and office buildings.

Description

technical field [0001] The invention relates to a lighting fixture, in particular to an integrated downlight. technical background [0002] There are many types of downlights on the market at present, but there are the following disadvantages: [0003] 1. Most of the lamp holders and light sources are split, which is costly, inconvenient to install, short in life, and unsafe for long-term use. The lamp holders of these downlights are separated from the light source, and hardware lamp holders are required to fix the lamp holders, and energy-saving lamp lamp holders also need to be installed, resulting in high cost; [0004] 2. The wiring of these downlights is also inconvenient, and it needs to be wired with terminal blocks, and it needs to be protected with a protective cover; [0005] 3. The lamp tube is in working condition for a long time, and the heat is too concentrated in the reflector cup, which will easily cause the reduction of light efficiency and the shortening ...

Problems solved by technology

[0003] 1. Most of the lamp holders and light sources are split, with high cost, inconvenient installation, short life, and unsafe for long-term use

The lamp holders of these downlights are separated from the light source, and hardware lamp holders are required to fix the lamp holders, and energy-saving lamp lamp holders also need to be installed, resulting in high cost;

[0004] 2. The wiring of these downlights is also inconvenient, and it needs to be wired with terminal blocks, and it needs to be protected with a protective cover;

[0005] 3. The lamp tube is in working condition for a long time, and the heat is too concentrated in the reflector cup, which will easily cause the reduction of light efficiency and the shortening of the life of the light source;

[0006] 4. Both the lamp holder and the lamp tube are installed in the reflective cup, and the reflective surface cannot be fully utilized;

Using low-cost incandescent lamps as light sources, the luminous efficiency is relatively low, only about 12%-18% can be converted into light energy, and the service life is usually not more than 1000 hours; using ordinary hot cathode fluorescent lamps as light sources, due to the use of rectifier drive, The lamp will turn on and off 50 times per second with the 50Hz AC rectifier, and there is a stroboscopic phenomenon; the service life of the lamp is relatively short, only about 8000 hours; the color rendering is poor, it is not resistant to frequent switching, and due to the mercury in the energy-saving lamp The content is difficult to control, which is not conducive to environmental protection

In actual application, most LED lights have problems such as heat dissipation, power utilization, luminous efficiency, and light decay, so the life span is difficult to meet the set standard, and the color rendering index of LED lights is low, which is easy to cause light pollution and lead to myopia, especially LED lights. Due to the blue light chip used in the lamp, it belongs to single-wavelength blue light, and it is easy to cause eye diseases when used for a long time
