technical field

The utility model relates to the field of lighting equipment, in particular to a lamp.

Background technique

With the rapid development of economic life, energy consumption is increasing, and energy-saving and environmental protection technology has attracted more and more attention. Among them, the field of energy-saving lamps is developing very rapidly, and various types of energy-saving lamps emerge in endlessly. In recent years, With the rapid development of science and technology, LED lamps for lighting have made significant progress in terms of cost and performance. Compared with traditional lighting equipment, modern LED lamps have advantages such as long service life, short start-up time and good energy-saving performance. .

As we all know, the structure of many LED lighting devices currently on the market is to solder and install multiple miniature LED lights in series on circuit boards or aluminum substrates, and the electrodes of the LED lights are connected to the power supply terminal through conductive wires, that is, , after the existing LED lighting equipment is finished, the LED lights cannot be partially disassembled. If some LED lights are damaged during use and cannot emit light and affect the luminous effect, the damaged LED lights cannot be replaced separately, but need to be replaced. The entire LED light source increases the maintenance cost and difficulty of LED lighting equipment replacement, and the maintenance method requires professional skills and equipment, which is not suitable for popularization.

Furthermore, with the rapid development of LED technology, many LED lamps on the market tend to be miniaturized, especially high-power LED lamps also tend to be miniaturized. Taking high-power LED lamps as an example, the power used per unit area is getting larger and larger, and the heat generated is greater; in order to ensure the reliable and stable operation of high-power LED lamps, the heat generated must be discharged in time to prevent heat loss caused by heat. Accumulation leads to excessive temperature, which affects the actual service life of the LED lamp. In order to solve the problem of rapid heat dissipation, general LED lamps are equipped with metal heat dissipation parts, but when the LED is used, due to the high thermal conductivity of the metal heat dissipation parts, the temperature of the metal heat dissipation parts is high, which makes it in the heat dissipation process. Too high heat dissipation temperature not only shortens the service life of the LED lamp, but also adversely affects other nearby components. Moreover, since the metal heat dissipation component is easy to touch the conductive wire of the LED lamp, when the temperature of the metal heat dissipation component is too high, it is easy to melt the insulation skin on the surface of the conductive wire, causing the metal heat dissipation component to conduct electricity, and even cause the conductive line to break. Short circuit, which is easy to cause safety accidents, cannot meet the safety standards of the LED industry well. Furthermore, in order to ensure that the temperature of the metal heat dissipation component will not be too high, the volume of the metal heat dissipation component is often designed to be very large, which takes up a lot of space.

Moreover, the existing LED lamps also have the disadvantages of complex structure and the need to consume a lot of labor and capital costs for production and processing.

Therefore, there is an urgent need for a lamp to overcome the above-mentioned defects.

Better meet the safety standards of the industry. On the other hand, through the connection structure in which the heat dissipation soldering portion 42 is welded to the heat dissipation pad 30, the heat generated by the light emitting unit 40 can be better conducted to the heat dissipation pad 30, because the thermal conductivity of the heat dissipation pad 30 is greater than that of the insulating heat sink. The thermal conductivity of 10, so that the heat generated by the light-emitting unit 40 can be temporarily stored in the heat dissipation pad 30 and then dissipated through the insulating heat sink 10, so that the temperature of the insulating heat sink 10 is lower than the temperature of the heat dissipation pad 30, so that the insulation While the radiator 10 maintains a low heat dissipation temperature, it can dissipate the heat in time to prevent the light emitting unit 40 and the heat dissipation pad 30 from being at a high temperature, thereby ensuring the service life of the light emitting unit 40 and preventing damage to the light emitting unit 40. Nearby other components can cause adverse effects, and under the condition of maintaining the same heat dissipation temperature, the volume of the insulating radiator 10 will be smaller relative to the volume of the metal radiator, so that the volume of the insulating radiator 10 can be designed more Small size also makes the overall volume of the lamp 100 of the present utility model further reduced.
