Description

Combined LED lamps

technical field

The utility model relates to a combined light-emitting diode lamp, in particular to a combined lamp structure in which the light diffusion angle and the size of the lamp can be adjusted according to the requirements of the actual installation environment.

Background technique

In the era of environmental protection and energy saving, Light Emitting Diodes (LEDs) with small size, high brightness, long life and low power consumption have gradually replaced traditional light bulbs. For example, the European Union has phased out incandescent light bulbs since 2007. , and Australia will ban incandescent bulbs from 2010, and LED will gradually become the main component of lamps.

Although the above-mentioned LEDs have various advantages such as low power consumption and high brightness, they are prone to high temperature during the lighting process. Therefore, when designing LED lamps in the industry, most of them will design heat dissipation devices so that the heat generated by them can be eliminated in a timely manner. Get the most out of it.

The current common LED lamp 10, as shown in Figure 1 and Figure 2, is mainly composed of a lampshade 11 with a fin-shaped outer surface, a drive circuit group 12 and a plurality of LED lamp holders 13; The heat-conducting aluminum plate 111 and the LED lamp caps 13 are respectively installed on the heat-conducting aluminum plate 111, and each LED lamp cap 13 is lighted by the driving circuit group 12, and the heat generated by the LED lamp cap 13 being turned on will be generated by the heat-conducting aluminum plate 111 The heat is directly transferred to the lampshade 11, and dissipated by the multiple fins on the outer surface of the lampshade 11.

However, although the above-mentioned fin-shaped lampshade can effectively eliminate the heat energy generated by the LED lamp holder 13, many deficiencies as follows are found during actual use, installation and manufacture:

1. Although the above-mentioned fin-shaped lampshade 11 is used in small-sized lamps, the heat dissipation effect is good, but when it is used in large-sized lamps, the heat dissipation effect is not good. The reason is that the lampshade 11 required for large-scale lamps is large in size and heavy. , causing heat energy to easily accumulate in the center of the lampshade and cannot be smoothly discharged from the surrounding area, which will easily affect the performance and life of the LED lamp holder.

2. Since the size of the lamp depends on the installation site and the illuminance, if the above-mentioned integrally formed fin-shaped lampshade is used, it will not be possible to change the required lighting angle at any time depending on the environmental conditions. The industry must design various sizes in advance and provide Lampshade molds that make LED lights exhibit different diffusion angles to meet demand. Since the lighting angles required by each environment may not be the same, it will not be possible to obtain a lamp that can correspond to each environment in one form in this way, so it is necessary to design a variety of lampshades, which will increase a lot of production costs and material inventory , for today's industry that emphasizes low cost and low inventory, there is indeed considerable room for improvement.

Therefore, how to effectively improve the LED lamps so that the diffusion angle and the size of the lamps can be adjusted according to the environmental requirements without affecting the heat dissipation effect due to the size of the lamps is the subject of the present invention.
