An illuminating device for plant cultivation to cultivate plants has a base, a light source, a light converging plate, a position-adjusting device and a distance sensor. A height of the plants is detected by the distance sensor, and then a distance between the light source and the light converging plate is adjusted according to the height detected, and as a result, an illumination field of the light source is altered by the light converging plate. Therefore, an illumination field of the light passing through the converging plate is narrower to illuminate the plants located farther away and prevents waste of light energy. When the plants grow higher, the distance between the light source and the light converging plate is adjusted to provide a wider illumination field to ensure that light can be distributed evenly among the plants. Utilization efficiency of light energy is therefore improved.

Illuminating device for plant cultivation

A light comprises a light case, an illuminating assembly, and an adjusting assembly. The light case has a first side segment. The illuminating assembly is mounted inside the light case, is pivoted on the first side segment, and has a base having a pivoting segment pivoted on the first side segment. The at least one lighting unit is mounted on the base. The adjusting assembly is mounted on the first side segment of the light case, is connected to the base, extends outside the light case, and is capable of tilting the illuminating assembly. Thus, a user is allowed to adjust a light emitting direction of the illuminating assembly, which is mounted inside the light case, via the adjusting assembly, which extends outside the light case, without tilting the light case.

Light having light emitting direction adjustable from inner side of light case

A heat-dissipating downlight lamp holder has a lamp holding unit, multiple fins and a bottom board. The fins are mounted on a periphery of the lamp holding unit to effectively dissipate heat of a light bulb mounted in the lamp holding unit out of the lamp holder. The bottom board located underneath the lamp holding unit has multiple air inlets formed through the bottom board to let cold air under the lamp holder enter the lamp holding unit through the air inlets. By convection, heat dissipated from the fins is carried away from the downlight, thereby effectively reducing heat accumulated by the light bulb and preventing the light bulb from being damaged by high heat.

Heat-dissipating downlight lamp holder

An LED lamp having a heat-dissipating mechanism has a top casing, a heat-conducting tube and a bottom casing. The top casing has a foundation board, a lamp holder and multiple fins. The foundation board has a first tube guide formed around and protruding downwardly from a perimeter of the foundation board and is made of a metal material. The lamp holder is hollow and centrally mounted through the top casing, and has a second tube guide formed on a bottom thereof. The fins are radially formed on a top of the foundation board and around the lamp holder. The heat-conducting tube is mounted against one side of the first tube guide and within the second tube guide. The bottom casing is securely combined with the top casing. Besides the fins, the heat-conducting tube enlarges the contact area with the top casing, thereby enhancing the heat-dissipating efficiency.

Light-emitting diode lamp

A waterproof LED lamp has a lamp housing, a top lid, a base and a power contact assembly. The lamp housing has an LED circuit board mounted therein. The top lid is mounted on the lamp housing and above the LED circuit board. A lid seal ring is mounted between the top lid and the lamp housing to prevent moisture from entering the lamp housing. The base has multiple LED modules mounted therein and has a base seal ring mounted between the lamp housing and the base to prevent moisture from entering the lamp housing. A heat-conducting tube is mounted inside the lamp housing. A waterproof insulation layer sheathed on the heat-conducting tube and a gasket mounted between the base and the power contact assembly prevent moisture entering the lamp housing through the power contact assembly and the base. Accordingly, an overall waterproof effect can be achieved.

Waterproof LED lamp

Flood light

A light string is composed of multiple light emitting units. Each light emitting unit utilizes multiple LEDs as the light emitting source to generate various light colors for enriching visual effects. Further, the light string is able to adhere to form any particular configuration as an attractive advertising device. By using the LEDs as the light source, power consumed by the light string is very low and operators of the light string are not exposed to high voltages.
