Lighting Improvement Device with Heat Dissipation Performance

technical field

The utility model relates to a lighting improvement device with heat dissipation performance, in particular to a lighting device main body and a conversion unit, which can achieve the purpose of improving convenience, obtaining uniform light shape of visible light and increasing heat dissipation effect. Lighting improvements.

Background technique

At present, due to the breakthrough of technical bottlenecks such as poor luminous power of traditional LEDs, LEDs can not only be used in indicator lights or auxiliary lights of general electrical appliances, but can also be used in the field of lighting equipment. Moreover, the current operating current of high-power LEDs can reach more than 2 amperes, which is more than 100 times that of traditional LEDs with an operating current of only 20 mA, and the luminous power of a single high-power LED is greater than the total luminous power of hundreds of traditional LEDs. Therefore, the brightness is quite high, and it is quite convenient to use. However, since the new type of high-power LED has the characteristics of high operating current, the heat dissipation cannot be completely solved in use.

Generally speaking, although there are currently heat sinks designed for high-power LEDs in order to achieve the purpose of heat dissipation, but due to the influence of poor design of heat sinks, the temperature of high-power LEDs is too high, resulting in the problem of LED burnout. . Moreover, although LEDs have many advantages, because the divergence angle of the light source emitted by the LED is about 15° to 120°, a general reflector lampshade cannot effectively reflect the diffused light source of the LED in the same direction. And the current method of making LED focus is to add a spherical convex lens to the front end of the LED flashlight to focus the light source. However, this method will lead to uneven light shape shadows in the LED light due to the concentration of the focal length of the LED; and if the focal length of the LED light source is poorly adjusted, the visible distance of the LED light source will be too short and the light shape will be uneven. .

Therefore, how to develop a method to increase the visible distance and uniform light shape of the light source generated by the LED, and to provide a better heat dissipation effect of the LED has also become an urgent problem to be solved.

In view of this, the designer of this utility model based on the user's needs and accumulated design experience in this industry for many years, innovated a lighting improvement device with heat dissipation performance for the industry to use.
