Problems solved by technology

[0005] However, although the above-mentioned "LED light bulb with light type and heat dissipation" can achieve the expected effect of controlling the light type without using secondary optical design, it is also found in its actual operation and use that it needs to be placed in a transparent cover. Phosphor powder is used inside to control the light pattern, resulting in a large area of ​​the transparent cover, and an increase in the relative fluorescent dose required, which in turn leads to an increase in production costs

Abstract

A light emitting diode device with higher heat dissipation and controllable light pattern is revealed. The light emitting diode device includes a light fixture reflector and a plurality of light emitting diodes fixed on surface of the light fixture reflector. By heat conduction, heat convection, and heat radiation of electrons of the light fixture reflector, heat is dissipated. Light pattern is controlled by adjustment of reflection angle of the light fixture reflector. Thus the manufacturing cost is reduced and the light emitting diode device is having more practical value.

Description

technical field [0001] The invention relates to a light-emitting diode capable of heat dissipation and controllable light type, in particular to a light-emitting diode that can directly dissipate heat by using a lamp reflector, and can control the light type by adjusting the reflection angle of the lamp reflector, thereby reducing the overall production cost , and the innovative design of light-emitting diodes with heat dissipation and controllable light pattern is more practical in its overall implementation and use. Background technique [0002] At present, the heat dissipation mechanism used by the common light-emitting diode light source mainly conducts the heat generated by the light-emitting diode to the radiator with a large surface area in the form of heat conduction, and then uses the large surface area and shape of the radiator to generate efficient heat. Radiation and heat convection effectively remove the heat generated by the LEDs. [0003] Although the above-m...
