Multifunctional reflector and down lamp

Abstract

The invention is applicable to the technical field of lighting equipment, and provides a multifunctional reflector and a down lamp. The multifunctional reflector comprises a reflective cup, and a heat insulating plate, wherein the heat insulating plate is arranged at the tail end of the reflective cup and consists of a heat insulating bottom board and heat conducting sheets rolling over along the edge of the heat insulating bottom board, a through hole is arranged in the center of the heat insulating bottom board, a barrel capable of penetrating the through hole in a matching manner is arranged at the tail end of the reflective cup, and the heat insulating plate is sheathed on the barrel through the through hole and is connected with the reflective cup. The down lamp adopts the multifunction reflector. The multifunctional reflector is simple in structure, low in cost and convenient to install, not only has good reflection function, but also has good function of reducing the internal temperature of the down lamp, thereby being capable of effectively playing roles of protecting a light source and a lamp cap, and also greatly reducing the possibilities of causing safety accidents due to ultrahigh temperature in the down lamp.

Description

technical field [0001] The invention belongs to the technical field of lighting equipment, and more specifically relates to a multifunctional reflector and a downlight using the multifunctional reflector. Background technique [0002] There are two types of downlights: exposed and concealed. Among them, the concealed downlight is a hidden lighting fixture embedded in the ceiling. Its biggest feature is that it does not occupy the external space and can maintain the overall unity and perfection of architectural decoration. The perfect unity of the ceiling art will not be destroyed because of the setting of the lamps. And all the light of the downlight is projected downward, which belongs to direct light distribution, and different reflectors, lenses, blinds, and bulbs can be used to obtain different light effects. In addition, the downlight can increase the soft atmosphere of the space, create a warm feeling and reduce the sense of oppression in the space. Because downlight...

Problems solved by technology

[0003] At present, many lighting downlights, especially high-power gas discharge downlights, have a high temperature inside the lamp tube, which often exceeds the light source (such as OSRAM quartz metal halide bulb shell safety temperature: 330 ℃) and lamp holder (such as OSRAM quartz metal halide lamp lamp holder). Safety temperature: 190℃) The specified safety temperature can easily cause damage to the lamps and even cause accidents
