Description

LED replacement light sources and LED ceiling lights compatible with traditional downlights

technical field

The invention relates to an LED lighting technology, in particular to an LED replacement light source adapted to a traditional downlight and a flexible telescopic LED ceiling light.

Background technique

Compared with traditional lighting, LED lighting has more energy-saving and higher-quality light performance. For the newly increased lighting requirements on the ceiling, LED lighting is generally preferred in home, business, and engineering, especially LED downlights: as ceiling embedded LED lighting fixtures, it has a large heat dissipation area and long life; light distribution quality High, good lighting effect; has a good decorative effect;

There is a huge potential demand for direct replacement of the traditional light source in the traditional downlight installed on the ceiling with LED lighting, which has a huge stock. The traditional downlight is equipped with a standard lamp holder suitable for the lamp holder of the traditional light source. The vertical traditional downlight with the axis of the lamp holder perpendicular to the horizontal plane is shown in Figure 1, and the horizontal traditional downlight with the axis of the lamp base parallel to the horizontal plane is shown in Figure 2. There is a decorative ring 101 with a hole under the traditional downlight, and a reflector 102 is placed inside the aperture of the decorative ring 101; the traditional downlight stipulates the size of the caliber D4 of the lamp that matches the opening of the ceiling installation aperture _D0 , and the caliber of the lamp D4 The size is larger than the aperture D3 of the decorative ring 101 . Due to the special structure of traditional downlights, there is currently no reasonable solution to directly replace the traditional light sources in traditional downlights with existing LED lighting products. The reasons are:

If the national standard GBT29294 standard LED downlight as shown in Figure 11 is used to replace the traditional light source in the traditional downlight, since the national standard GBT29294 has stipulated that the diameter D of the LED downlight is the same as the diameter D4 of the traditional downlight Therefore, the caliber D of the LED downlight conforming to the national standard GBT29294 must be larger than the aperture D3 of the decorative circle of the traditional downlight shown in Figure 1 and Figure 2, and cannot be placed in the traditional downlight, and the LED downlight has no A lamp head adapted to a standard lamp holder in a traditional downlight is provided. Therefore, the traditional light source in the traditional downlight cannot be directly replaced by the LED downlight. For this reason, in order to replace the light source in the traditional downlight, the LED downlight must be dismantled. People such as electricians can't do it, ordinary people can't do it, the installation is complicated and inconvenient, and there is also the problem of difficult secondary replacement of LED downlights.

If the LED bulb lamp is used to replace the traditional light source in the traditional downlight, the replacement and installation process is convenient. However, since the reflective cup on the vertical traditional downlight is a semi-closed space structure, the LED bulb lamp must be installed in the reflective cup, and the heat generated during the lighting process cannot be dissipated, thus increasing the temperature inside the traditional downlight. Seriously shorten the life of the LED bulb lamp; because the reflector in the horizontal traditional downlight is a semi-closed space structure, and the lamp holder is set horizontally, the LED bulb must be installed horizontally in the reflector, except for the high temperature that affects the LED In addition to the life of the bulb, because the light distribution of the LED bulb is different from the light distribution of the traditional light source, the ordinary LED bulb is directly installed in this horizontal traditional downlight, which reduces the effect of the light distribution of the lamp and reduces the light output. Efficiency, reducing the energy-saving effect of installing LED lights.

The patent application publication number is CN104763952A discloses an LED ceiling lamp, which includes a lamp holder, a power module, a positioning telescopic lamp housing, a radiator, an LED light-emitting element, and a light-transmitting cover; The first housing and the second housing are positioned to slide and cannot be relatively rotated on the vertical plane of the axis of the lamp head; the lamp head is connected to the top of the first housing, and the radiator is a hat-shaped structure with a brim. The outer surface of the top of the hat is fixedly connected to the bottom of the second lamp housing, the inner surface of the top of the hat is connected to the LED light-emitting element, and the brim of the hat is close to the corresponding embedded ceiling downlight opening; the outer surface of the light-transmitting cover The edge is connected to the inner surface of the heat sink to cover the LED light emitting element. This invention realizes that LED lighting directly replaces the traditional lighting in existing embedded downlights with a huge stock. The replacement method is simple, the LED lighting has a long service life, is easy to install, and has good decorative effects, which is of great significance to energy conservation and environmental protection. However, the structure of the LED ceiling lamp is complicated to slide along the axial direction of the lamp head, and the installation direction of the lamp head cannot be changed, especially for the traditional light source in the horizontal traditional downlight, which cannot be replaced.

In this regard, the present invention proposes an LED replacement light source that is compatible with traditional downlights, which can directly replace the traditional light sources in existing traditional downlights with huge stock, which is of great significance for accelerating the popularization and application of LED lighting, saving energy, and protecting the environment .
