A lighting apparatus includes a lens, a cup housing, a light source and a top cover. The cup housing has a surrounding wall and a light source holder. The cup housing is installed on a fixed platform. The light source is placed on the light source holder. The cup housing and the top cover form a container space for storing the lens and the light source. A top end of the lens is attached to the top cover. A second end of the lens faces to the light source. A relative distance between the lens and the light source is adjustable to change a light pattern of a output light of the light source. The output light is a light of the light source passing through the lens.

Lighting apparatus

A lighting apparatus includes a light source plate, a light passing cover, a sleeve housing and an air tube. The light source plate is mounted with a LED module for emitting a light. The LED module faces to the light passing cover to allow the light to pass through. The LED module is enclosed within a container space. The sleeve housing has a first end supporting the light source plate. The Edison cap is fixed to a second end of the sleeve housing. The air tube has a top opening connected to the container space for guiding a heated air in the container space away from the container space via the air tube.

A lighting apparatus includes a driver module, a light source, a main housing and an optical plate. The driver module converts an external power to a driving current. The light source includes multiple LED chips. The light source is coupled to to the drive module to emit a light. The main housing is used for disposing the driver module and the light source. The optical plate is detachably inserted into a sliding track of the main housing via a lateral opening of the main housing so that the optical plate is replaceable. The optical plate changes a light direction of the light emitted by the light source to a light opening. A first surface of the light opening is substantially perpendicular to a second surface of the lateral opening.

A light bulb apparatus includes a bulb shell, a light source module, a bulb head, a bottom pin and a driver module. The bulb shell has a light passing cover and a neck portion. The bulb head has a body portion and an Edison cap. A bottom pin is used for connecting a second electrode of the Edison socket. The driver module is enclosed by the bulb head. The driver module has a driver plate mounted with a driver component and a driver input terminal. The driver input terminal has a guiding groove. The driver input terminal has a first wiring clip, the bottom pin is inserted into the guiding groove via the entrance and engages the first wiring clip for electrically connected to the driver component.

Light bulb apparatus

A light bulb apparatus includes a cap connector, a light source, a heat sink module, a bulb shell and a reflective layer. The cap connector is used for connecting to an external power source. The bulb shell has a bottom part and a neck part. The reflective layer is disposed at the bottom part of the bulb shell for guiding a first light emitted from the LED module on the reflective layer to escape from the neck part of the bulb shell.

A light tube apparatus includes a light passing tube, a light strip, first cap end, a second cap end, a driver circuit board and a manual switch. The light passing tube are connected with the first cap end and the second cap end on opposite sides of the light passing tube. The manual switch is a fixed to the first cap end. The driver circuit board is at least partly enclosed by the first cap end. The manual switch has a switch sheath and a sliding switch. When a user moves the switch sheath, the sliding switch is moved by the switch sheath to change a position of the sliding switch for changing an operation parameter of the driver circuit.

Light tube apparatus

A light tube apparatus includes a tubular housing, a LED module, an EMI circuit, a rectifier circuit, a filter circuit, a conversion circuit, a safety circuit and a PWM modulation circuit. The safety circuit is connected to a dimming signal from a dimmer for preventing an incorrect connection when the dimmer is connected in wrong direction causing loop breakage. The PWM modulation circuit is connected to the conversion circuit and the safety circuit for performing a pulse width modulation for the dimming signal supplied to the conversion circuit for adjusting a luminance level of the LED module.

A driving circuit includes: a first connecting port for receiving a first signal during a first operating mode; a second connecting port for receiving a second signal during the first operating mode or receiving a third signal during a second operating mode; a first driving unit coupled to the first connecting port and the second connecting port, for driving an LED element according to the first signal and the second signal during the first operating mode; and a second driving unit coupled to the second connecting port, for driving the LED element according to the third signal during the second operating mode; wherein the second operating mode is different from the first operating mode.

LED driving circuit and LED apparatus

An elongated lamp tube has an elongated tube shell, two caps, a LED light source, a first power supply circuit, a second power supply circuit and a frequency switch circuit. The elongated lamp tube may be connected to first electrodes of a lamp fixture without a ballast or a lamp fixture with a ballast. The ballast converts an external power of an industrial frequency to a converted power of a working frequency. The frequency switch circuit is connected to the first power supply and the second power supply for blocking one of the first power supply circuit and the second power supply to supply driving current to the LED light source according to an input frequency of a received power.

LED light tube

AN LED tube apparatus has a tube body with two opposite ends fixed to a first cap and a second cap. AN LED module is placed in the tube body. The LED module has a driver circuit containing an electronic ballast that generates high frequency electric current. The first cap has two first metal pins to be inserted in a first socket end of a light tube bracket. The first metal pin clutches an end of a leading wire. The leading wire has a protective portion breaking off when the first metal pin is applied with a predetermined range of heat generated by the high frequency electric current when the LED tube apparatus is not operated properly.

Tubular lighting apparatus with protection portion

A light bulb apparatus has a bulb shell, LED modules, a light source plate, an inner tube and an outer cup. The light source plate has a substrate plate. The substrate plate and the inner tube are made of heat dissipation material like metal material. There is a pressing portion of a lateral side of the substrate plate pressing against an inner side of the inner tube part and there is a spacing portion of the lateral side of the substrate plate not engaging the inner side of the inner tube. The outer cup part has top part and a bottom part. The inner cup is placed inside the top part of the outer cup and pressing against the outer cup.
