Problems solved by technology

However, LEDs have their temperature-limited ratings in the operating mode. If they are used at high temperatures for a long time with insufficient heat dissipation, the aging of the LEDs will be accelerated, the luminous efficacy will be reduced, and the lifespan will be greatly shortened. Therefore, how to use Affecting the high temperature derivation of light-emitting diodes is a problem worth exploring
[0004] In the known technology, in order to achieve the effect of heat dissipation, most of the light-emitting modules that use light-emitting diodes as light sources are designed to increase the heat dissipation med

Embodiment Construction

[0032] Please refer to Figure 1 and Figure 2, which are schematic diagrams and three-dimensional exploded views of the light-emitting module that automatically adjusts the light-emitting power of the present invention. The LED module 1 is covered by the outer sleeve 3 and then electrically connected with the power control board 2 . In the light emitting diode module 1, at least one light emitting diode crystal grain 12 is included on the metal substrate 11; and a temperature sensing unit 22 is included on the power control board 2 to connect the power control board 2 and the light emitting diode. When the diode module 1 is combined, the temperature of the environment where the light-emitting diode die 12 is detected by physically leaning against the metal substrate 11, and different temperature measurement values ​​are generated at any time to automatically adjust the luminous power of the light-emitting module .

[0033] Please refer to FIG. 3 , which is a block diagram of a...

Abstract

The present invention is one kind of light emitting module with automatically regulated light emitting power and its power regulating method. The light emitting module includes one LED module and one power source controlling board connected electrically to the LED module. The power source controlling board has and one thermal sensing unit for measuring environment temperature and one power source adaptor unit to convert the first power source into the second power source based on the measured temperature value. The light emitting power is regulated automatically, that is, the light emitting power is lowered to lower the temperature in condition of higher environment temperature and raised to raise brightness in condition of lower environment temperature.

Description

technical field [0001] The invention relates to a light emitting module, in particular to a light emitting module which automatically adjusts the light emitting power and a method for automatically adjusting the light emitting power. Background technique [0002] Light-emitting diodes have been paid more and more attention in recent years, especially for high-brightness light-emitting diodes (HB LEDs), the demand has been greatly increased, and a frenzy has been set off in the industry. Compared with traditional incandescent light bulbs, high-brightness light-emitting diodes have the advantages of power saving, long service life, high durability and fast response. At present, the popular applications of high-brightness light-emitting diodes are not only in general lighting, commodity lighting, automotive lighting, outdoor billboards and traffic information display, but also due to the progress and development of consumer electronics products, it has become more popular in va...
