Abstract: An LED bulb includes a connector for electrically connecting with a power supply, a heat sink disposed on the connector, and a plurality of LEDs mounted the heat sink. The heat sink includes a base, a tube extending downwardly from a first face of the base, and a plurality of fins extending outwardly from an outer circumference of the tube. The LEDs are attached on a second face of the base. The base defines a plurality of through tunnels extending through the base from the first face to the second face of the base.

Abstract: A solar cell includes a base, a substrate, a number of solar chips and a light pervious cover. The substrate is received in the base, the solar chips are electrically mounted on the substrate. The light pervious cover covers the solar chips in the base. The light pervious cover includes a number of light converging portions corresponding to the solar chips and a number of extending portions aligned with the respective light converging portions. Each extending portion is engaged with a corresponding solar chip.

Abstract: A depth detection method includes the following steps. First, first and second video data are shot. Next, the first and second video data are compared to obtain initial similarity data including r×c×d initial similarity elements, wherein r, c and d are natural numbers greater than 1. Then, an accumulation operation is performed, with each similarity element serving as a center, according to a reference mask to obtain an iteration parameter. Next, n times of iteration update operations are performed on the initial similarity data according to the iteration parameter to generate updated similarity data. Then, it is judged whether the updated similarity data satisfy a character verification condition. If yes, the updated similarity data is converted into depth distribution data.

Abstract: A method for dynamically adjusting a waiting time of handwriting inputs is applied to an electronic equipment having a handwriting input device. When a waiting-for-input time after the handwriting input device receives a handwriting input exceeds a waiting time of the electronic equipment, the electronic equipment performs a handwriting recognition upon the handwriting input so as to display a candidate word list. The method includes the following steps: receiving the handwriting input; generating a writing speed according to the handwriting input; and setting the waiting time of the electronic equipment according to the writing speed.

Abstract: A modularly expandable lamp holder comprises first and second assembling surfaces. The first assembling surface has an elongated protrusion formed thereon, which includes a first portion adjacent to the first assembling surface and a second portion remote from the first assembling surface and having a size larger than that of the first portion. The second assembling surface defines an elongated groove therein, which has a configuration matching that of the protrusion. The lamp holder can be mechanically assembled with another lamp holder of this kind by the engagement of the protrusion of the lamp holder and the groove of another lamp holder.

Abstract: An LED illuminating apparatus includes a lampshade, a cover engaged with the lampshade, a heat dissipation module received in a hollow tube cooperatively formed by the engaged lampshade and cover, a light source engaged on the heat dissipation module, and two connectors secured at opposite ends of the lampshade and the cover. The lampshade defines a plurality of vents therein. The light source faces the cover and light emitted from the light source radiates out of the LED illuminating apparatus through the cover.

Abstract: An exemplary heat dissipation device includes an elongated main body, a number of heat sinks, and a number of airflow channels. The main body has a central axis, and includes a first portion and a second portion. The second portion has an end distant from the first portion which is configured for supporting at least one item selected from the group consisting of a solid-state light source and a circuit board having a solid-state light source mounted thereon. The heat sinks are arranged around the first portion in sequence along the central axis of the main body, and spaced from one another. Each heat sink includes a number of fins extending out from the first portion radially. The airflow channel is defined between each two neighboring heat sinks.

Abstract: An illuminating device includes a receiving base and at least one light source. The receiving base has at least one receiving space defined therein, and at least one fixing post is positioned adjacent to the corresponding at least one receiving space. The at least one light source is positioned in the at least one receiving space for emitting light. Each light source comprises a light-pervious plate and a LED array located on a side of the light-pervious plate. The light-pervious plate comprises at least one first through hole with the at least one fixing post extending therethrough, the light-pervious plate is fixed to the receiving base in the corresponding receiving space of the receiving base.
