    摘要: A structure of heat dissipation substrate of power LED and a device made thereof overcomes drawbacks such as complex structure of power LED, strict manufacturing process, low production efficiency, high production cost, and unreliable product quality. The structure of heat dissipation substrate includes a one-piece circuit board having a counterbore and metal lines thereon, wherein the counterbore is formed by a through hole and a blind hole communicating with each other, and the through hole is smaller than the blind hole, and both of them share the same direction of axis; the heat sink has a one-piece terraced structure formed by a upper terrace and a lower terrace; the heat sink matches the counterbore to form a firm fit; a plurality of counterbores may be arranged on the circuit board; the circuit board may also comprise a plurality of position lines for cutting and a plurality of slots and/or holes. The power LED device manufactured by using the heat dissipation substrate includes a heat sink, a circuit board with a counterbore, a LED chip, bonding wires, and encapsulation colloid. The encapsulation colloid covers the side of the circuit board carrying the chip and lead lines, and an external electrode part is kept outside. The encapsulation colloid functions not only as a sealing layer for sealing the chip and the bonding wire, but also as an optical lens integrated with the device.

    摘要: Provided is an LED display unit group, comprising: an insulation substrate, a front circuit board, and a back circuit board. The front circuit board is divided into pixel areas arranged in an array of 2m rows and 2n columns. Each pixel area comprises three A-electrode pads, three LED light-emitting chips of different light emission colors, and B-electrode pads corresponding to the three LED light-emitting chips. In each pixel area, the electrode A of each LED light-emitting chip is electrically connected to a corresponding A-electrode pad, and the electrode B of each LED light-emitting chip is electrically connected to a corresponding B-electrode pad. In the same column of pixel areas, B-electrode pads corresponding to all LED light-emitting chips are electrically connected to each other. In the same row of pixel areas, A-electrode pads corresponding to LED light-emitting chips of the same light emission color are electrically connected to each other.

    摘要: A white light emitting device, a light bar and a light apparatus. A relative spectrum of the white light emitting device is ϕ(λ). A relative spectrum of a black body radiation with a corresponding color temperature is S(λ). An area normalization is performed on ϕ(λ) and S(λ) to convert an equal energy spectrum ϕ′(λ) of the white light emitting device and an equal energy spectrum S′(λ) of the black body radiation with the corresponding color temperature. A degree of similarity R of the equal energy spectrum of the white light emitting device and the equal energy spectrum of the black body radiation satisfies the following formula:

    摘要: Provided are a bracket and a LED device. The bracket includes a lead frame and a molded structure connected to the lead frame. The lead frame includes a first lead portion, a second lead portion, and a barrier structure. The first lead portion includes a first base. The second lead portion includes a second base spaced from the first base. A gap between the first base and the second base forms a channel. The barrier structure is disposed on a side of at least one of the first base or the second base facing the channel. The barrier structure is disposed between two opposite ends of the first base and/or the second base and protrudes from the first base and/or the second base, and a length between two opposite ends of the channel is greater than a length of a middle part so that a “wide-narrow-wide” pattern is formed.
