Description

A kind of LED ceiling lamp

Technical field:

The utility model relates to the technical field of lighting lamp products, in particular to an LED ceiling lamp with compact structure, excellent heat dissipation effect and excellent lighting effect.

Background technique:

The light source of existing ceiling lamps usually adopts ordinary incandescent lamps. As we all know, traditional incandescent lamps have high energy consumption and very low energy utilization rate. About one-tenth of the energy is converted into light energy. It was wasted in vain with the form of heat energy, so people are trying to think of way to replace incandescent lamp with new light source always. Therefore, energy-saving lamps have emerged as the times require. Because they are cheaper and easier to manufacture, they have been widely used and tend to gradually replace incandescent lamps. Energy-saving lamps use the principle of electronic luminescence excitation to emit light. Compared with incandescent lamps, energy-saving lamps have the advantage of saving electricity, but one disadvantage of energy-saving lamps is that energy-saving lamps contain mercury, and mercury plays an intermediary role in energy-saving lamps. Without mercury, CFLs would not glow. As a result, energy-saving lamps will be polluted with mercury during the production process and after they are discarded. In addition, energy-saving lamps are still made of glass, which is easy to break, difficult to transport, and difficult to install. Secondly, its power consumption is still relatively large. Finally, energy-saving lamps are easily damaged and have a short service life.

At present, the development direction of energy-saving lighting appliances is LED lamps. Compared with the above-mentioned lighting fixtures, LED lights have the following advantages:

1. Energy saving. The energy consumption of white light LED is only 1/10 of that of incandescent lamp and 1/4 of that of energy-saving lamp.

2. Long service life. The life of LED lamps can reach more than 100,000 hours, which is much higher than that of incandescent lamps and energy-saving lamps.

3. It can be started frequently. If traditional energy-saving lamps and incandescent lamps are frequently turned on or off, the filament will be black and easily broken, but LED lights will not.

4. Solid-state packaging, which belongs to the type of cold light source, so it is very convenient to transport and install, and can be installed in any miniature and closed equipment without fear of vibration.

5. Environmental protection, no harmful substances of mercury.

Based on the above advantages, LEDs are gradually adopted as light sources in existing ceiling lamps, which are energy-saving, small in size, and convenient for transportation and assembly. However, during the working process of the LED in the ceiling lamp, 70%~80% of the input power is converted into heat that cannot be released by radiation, and the size of the LED chip is small. If the heat dissipation is not good, the temperature of the LED chip will increase, causing thermal stress. Uneven distribution leads to problems such as reduced chip luminous efficiency and phosphor lasing efficiency. In order to ensure the service life of LEDs and improve the luminous efficiency of LEDs, it is generally necessary to perform good heat dissipation treatment on LEDs.

In the prior art, the existing radiators are installed for dissipating heat from the LED chips, and the heat generated by the radiators to the LED chips is conducted to the radiators through circuit boards, substrates, heat-conducting adhesives, etc. in the form of heat conduction.
