摘要:
A lamp has a light tube, an illuminant module mounted in the light tube and two end caps mounted respectively on two opposite ends of the light tube. A slot being substantially inverted T-shaped in cross-section is formed in and axially along the light tube and the end caps. A guide rail or a pair of resilient plates is disposed at a presupposed position and is mounted through the slot of the lamp to hold the lamp. An amount of lamps that is held on the guide rail or the pair of resilient plates is changeable according to needful brightness. Therefore, disposing the lamp is easy, quick and convenient and a total cost for disposing the lamp is low.

A LED lighting device capable of changing illumination color has an adjusting circuit, a bridge rectifier and multiple LED modules. The adjusting circuit is connected to a light regulator and produces a regulated input voltage in response to the output voltage of the light regulator. The bridge rectifier converts the regulated input voltage to a DC voltage to be applied to drive at least one of the LED modules. When the output voltage of the light regulator is changed, at least one of the LED modules receiving the DC voltage varies the illuminating intensity. Since the illuminating intensity of at least one of the LED modules is adjustable, the different colored lights emitted from all the LED modules are mixed to produce a desired light color.

A LED lamp brightness adjusting circuit has a regulating circuit, multiple rectification diodes and filtering capacitors. Each filtering capacitor is connectable to a LED module in parallel. The LED lamp brightness adjusting circuit is connected to an output terminal of a light regulator. Based on the control of light regulator, the regulating circuit produces a regulated AC input voltage. The positive and negative half cycles of the regulated AC input voltage are further rectified and filtered to drive different corresponding LED modules. Therefore, the amplitude of the drive voltages for the LED modules are controllable to adjust the brightness of the emitted light.

An LED road light has a heat sink embedded with an LED module, a base and a light pole holder assembly. The base, the heat sink and the light pole holder assembly are assembled by slidably and respectively mounting ribs into slots. Accordingly, the contact area of such engagement is relatively larger than that using screws, thereby enhancing combined strength and extending the life duration of the LED road light. Besides, the engagement mechanism using ribs and slots also provide workers a convenient and time-saving assembling process.
