Description

Down lamp

[ technical field ] A method for producing a semiconductor device

The utility model relates to a lamp, specifically speaking are down lamps and lanterns.

[ background of the invention ]

The LED down lamp is a product developed by improving the traditional down lamp by applying a novel LED lighting source, and has the following advantages compared with the traditional down lamp: energy saving, low carbon, long service life, good color rendering and high response speed. The LED down lamp is more attractive and light in design, the whole unification and perfection of architectural decoration can be kept during installation, the arrangement of the lamp is not damaged, the light source is hidden inside the architectural decoration, the light source is not exposed, glare is avoided, and the visual effect of people is soft and uniform.

An LED tube light is a lighting lamp which is embedded into a ceiling and emits light downwards. The LED down lamp belongs to a directional lighting lamp, can receive light only on the opposite surface of the LED down lamp, has a light beam angle of light condensation, and has concentrated light and strong light-dark contrast. The illumination object is more prominent, the lumen degree is higher, and the quiet environment atmosphere is further set off. The LED down lamp mainly realizes illumination through a diode light emitting mode, the service life of the LED down lamp mainly depends on a solid LED light source and a driving heat dissipation part, the service life of the LED down lamp reaches more than 80000 hours in 2018, along with continuous research and common use of LED technology, the LED down lamp basically reaches a relatively ideal state in the aspects of driving and heat dissipation, and compared with a common halogen down lamp, the service life of a high-quality LED down lamp sold in the market basically reaches more than 80000 hours. The existing down lamp structure is fixed on a lamp body through a lamp panel (or an integrated packaging LED module) by screws, the mode is complex, the biggest problem is that the contact surface of the lamp panel (or the integrated packaging LED module) and the lamp body has great thermal resistance, the heat dissipation of an LED is seriously influenced, and the over-high temperature is a known main reason for shortening the service life of the LED. The down lamp is installed and all needs a spring, and present practice is to add a support on the lamp body and fix the spring, and this kind of mode needs welding or fixes with the screw, and is complicated and with high costs. The power cord is also usually screwed, which makes assembly complicated. The light emitting surface of the downlight is usually provided with a diffuser plate for making the emitted light more uniform and soft, and this method is not complicated to assemble, but requires expensive injection molding dies for producing the diffuser plate.
