Description

Lamp structure

technical field

The utility model relates to a lamp structure, in particular to a light source device with a plurality of arrays in the lamp housing, and the bottom of the light source device uses a heat conduction part to quickly conduct the heat source vertically, so that the heat source that contacts the bottom of the heat conduction part The radiating part can receive heat evenly, and form a heat collecting area as a timely adjustment with the external temperature of the lamp shell, buffer the temperature inside the lamp, and avoid rapid heating and cooling.

Background technique

Press, lamps play a very important role at night, providing bright lighting and clear visibility, so that night activities can be carried out smoothly. In addition to indoor lighting, there are also outdoor lighting for lighting at night. Different lighting methods can still be used and used at night. However, the most commonly used lighting sources for lampshades are light bulbs, fluorescent lamps, and searchlights. It gathers in the lampshade and is not easy to disperse. It also causes the bulb or fluorescent lamp to accelerate the aging speed of the lamp and shorten its service life in the high temperature environment, and the replacement rate is also relatively increased. In order to solve the problems caused by lighting, there are The industry has developed the use of high-power light-emitting diodes (LEDs) as lighting, which can slightly improve the problem of high temperature generated by lighting, but the heat energy of the lamps will accumulate inside when they are in use, and cannot be quickly dissipated outward. Long, the lamps will still withstand high temperature and be difficult to dissipate, and the heat will still accumulate inside the lamp, affecting the service life of the lamp and the lighting source; moreover, the lamps installed outdoors will be exposed to the heat of the sun during the day, resulting in residual sunlight inside the lamp. The heat energy of the sun, at night, the lighting source of the lamp starts to emit light, and a high heat temperature is generated, which causes the internal temperature of the lamp to change from day to night, and the continuous heat energy increases even higher, and because the heat dissipation is not easy, the lamp accumulates more heat energy. The service life of lamps and lighting sources is shortened.

At present, the lamps and lanterns used for lighting will not be easily dissipated due to the accumulation of heat energy during use, and there are many defects, such as:

(1) The indoor lighting source is usually installed on the ceiling or on the light steel frame of the decoration. The heat energy generated when emitting light is blocked by the ceiling and the decoration. Due to the exposure to heat, the aging phenomenon occurs early, the service life is shortened, and the surrounding ceiling or decoration is also subjected to high temperature.

(2) The lamps and lanterns installed outdoors will be exposed to the heat of the sun during the day and the heat of the lighting source at night, so that the lamps and lighting sources will be in a high-heat environment for a long time, causing the lamps and lighting sources to be heated early. Aging phenomenon will affect the service life of lamps and lanterns.

(3) If the lighting source of the lamp adopts high-power light-emitting diodes (LEDs), it will also use a large number of high-power light-emitting diodes, and heat energy will be generated when the light is illuminated at the same time, and it cannot be dissipated by the lamp, which will still cause heat energy to accumulate Inside the lamp, it affects the aging and damage of the structural quality of the lamp, and reduces the service life of high-power light-emitting diodes.

Therefore, how to solve the problem that the heat energy generated by the lighting cannot be quickly dissipated in the existing lamps, which further affects the service life of the lamps, is the direction that relevant manufacturers engaged in this industry are eager to study and improve.

Therefore, in view of the above-mentioned problems and defects, the designer of the utility model collected relevant information, evaluated and considered in many ways, and based on years of experience accumulated in this industry, after continuous trial and modification, he designed this kind of auxiliary lighting. A utility model patent for a lamp structure that uses a light source device to quickly dissipate heat was born.
