Description

A fixed structure and LED or OLED lighting fixture using the fixed structure

technical field

The utility model relates to an LED or OLED lighting fixture, in particular to a fixing structure for fixing a carrier in a LED or OLED lighting fixture to a lamp cup, or a lens to a carrier, and an LED or OLED lighting fixture using the fixing structure.

Background technique

LED is the abbreviation of Light Emitting Diode; OLED is the abbreviation of Organic Light Emitting Diode; these two light sources have been one of the important light sources in recent years. Because LED has the advantages of high luminous efficiency, long service life, not easy to damage, low power consumption, environmental protection and small size, it was often only used in the light of indicator lights and display panels in the early days due to insufficient luminous brightness. With breakthroughs in materials and related technologies, the luminous brightness of LEDs has been greatly improved, especially the emergence of white LEDs, which has made LEDs gradually replace the current traditional lighting equipment.

The heat dissipation problem of LED has always been the most concerned in the industry. Take the current LED lamps on the market (such as: bulb lamp, MR16, PAR lamp, etc.), in order to solve the problem of heat dissipation, most of the lamps adopt aluminum fin structure, and its huge weight has become the industry's another problem. In view of this, the inventor proposed a LED lighting fixture structure with good heat dissipation and light weight in the patent application number ZL200920308109.6, which solved the problem of poor heat dissipation and heavy weight of traditional lamps. Subsequently, the inventor proposed a multi-layer heat dissipation structure of LED lighting fixtures in the patent application number ZL200920313008.8, which greatly improved the heat dissipation efficiency of LED lighting fixtures. From the above two patents and the existing lighting fixtures on the market, most of the internal combination of lighting fixtures is fixed by glue or locking screws (for example, the glue between the carrier and the lamp cup is used to fix, the lens Or the decorative cover on it and the lamp cup or carrier are fixed by locking screws, etc.). However, there are many unstable factors in bonding with glue, so that the quality of the product cannot be reliably guaranteed; at the same time, it is not easy to be accepted by consumers. Combining and fixing the lighting fixtures by means of locking screws, although the product quality is guaranteed, the assembly is complicated and the cost is high. In view of this, the inventor will improve the structure of the previous lighting fixture.
