Abstract: A three-layered cold/hot controller comprises a semiconductor plate, a first metal plate, and a second metal plate. The semiconductor plate has a top and a bottom contact surface and connected with a power source. When the semiconductor plate is electrified, the top contact surface of the semiconductor plate forms a contact surface for decreasing temperature while the bottom contact surface of the semiconductor plate forms a contact surface for elevating temperature. The first metal plate is combined to the top contact surface of the semiconductor plate for conducting the heat between the first metal plate and the top contact surface. The second metal plate is combined to the bottom contact surface of the semiconductor plate for conducting the heat between the second metal plate and the bottom contact surface.

Abstract: In the field of opto-electronic technology, a three-dimensional (3D) light-emitting diode (LED) light-emitting plate is described. The 3D LED light-emitting plate includes an aluminum substrate. The aluminum substrate is vertically disposed. Notches are formed on an upper side of the aluminum substrate in a thickness direction. LED chips are mounted in the notches. A flexible circuit layer is disposed on a surface of the aluminum substrate. Each LED chip is connected to a circuit of the flexible circuit layer by a gold wire. A fluorescent colloid light-emitting shell is disposed outside each LED chip correspondingly. A cavity is formed between the LED chip and the fluorescent colloid light-emitting shell. A lower portion of the fluorescent colloid light-emitting shell is fixed on the aluminum substrate. The 3D LED light-emitting plate effectively improves the luminous brightness and efficiency of an LED and enlarges an effective light-emitting angle, and alleviates the problem of non-uniform light pattern and light color, such that an LED white light lamp can achieve the luminous effect of a tungsten lamp. The fluorescent colloid light-emitting shell wraps the LED chip, which not only protects the LED chip from dust and produces white light, but is also suitable for use in a severe environment. Moreover, the production cost is reduced due to the simple structure.
