LED (Light-Emitting Diode) embedded barrel lamp

Abstract

The invention discloses an LED embedded barrel lamp which comprises a front cover and a radiator, wherein the front cover and the radiator are matched and connected together, the radiator comprises a radiator body and a protecting cavity which is positioned outside the radiator body and shares the same bottom surface with the radiator body, and the inside of the protecting cavity body is provided with two chambers which are respectively a driving chamber for installing a driver and a terminal chamber for installing a wiring terminal. Through the invention, the structure of the LED embedded barrel lamp becomes concise, the LED embedded barrel lamp is beautified, and moreover, the structural layouts of the driving chamber and the terminal chamber are compact, and the manufacturing cost of the radiator can not be markedly increased. In addition, the driver and an LED light-source module of the invention are respectively arranged in different chambers, and the driver and the LED light-source module do not directly contact, thus, the heat transferred from the LED light-source module to the driver can be reduced, and the service life of the driver is prolonged.

Description

technical field [0001] The invention relates to a practical LED downlight in the field of indoor lighting, in particular to a radiator for the LED downlight. Background technique [0002] At present, the light source of traditional embedded downlights widely used in indoor lighting places is still fluorescent lamps, but fluorescent lamps have the following defects: (1) fluorescent lamps contain mercury, which will cause a certain degree of mercury pollution; (2) fluorescent lamps are gas discharge The light source is not easy to realize intelligent control such as brightness adjustment and color temperature adjustment; (3) The corresponding embedded downlight has a loose structure, and the light source can be clearly seen, which is not beautiful enough; (4) In some specific indoor places, such as airports and other public transportation facilities, downlights need to be lit for a long time, and even the lighting time can reach 24 hours a day, and the service life and power c...

Problems solved by technology

[0002] At present, the light source of traditional embedded downlights widely used in indoor lighting places is still fluorescent lamps, but fluorescent lamps have the following defects: (1) fluorescent lamps contain mercury, which will cause a certain degree of mercury pollution; (2) fluorescent lamps are gas discharge The light source is not easy to realize intelligent control such as brightness adjustment and color temperature adjustment; (3) The corresponding embedded downlight has a loose structure, and the light source can be clearly seen, which is not beautiful enough; (4) In some specific indoor places, such as airports and other public transportation facilities, downlights need to be lit for a long time, and even the lighting time can reach 24 hours a day. The service life and power consumption of fluorescent lamps are difficult to meet the requirements

At present, most of the LED downlights on the market are 4-inch and 6-inch, and the structural design of the LED downlight is not reasonable enough. On the one hand, the drivers and connecting terminals are exposed, which greatly affects the aesthetics of the LED downlight. In terms of aesthetics, it highlights the advantages over fluorescent lamps; in addition, the heat sink design of the existing LED downlights has the problem of poor heat dissipation, which brings technical difficulties to the production of larger-sized LED downlights, and for larger spaces. The traditional downlights in large public indoor places, 4-inch and 6-inch LED downlights simply cannot meet the required lighting effects. Therefore, although LED downlights have many advantages compared to traditional fluorescent lamps, LED downlights are relatively small in space. Large venues are still not universally promoted
