DETAILED DESCRIPTION

(19) In FIG. 15, a lighting apparatus includes a base housing 7701, an elongated light source module 7706, and at least one holder hook 7707.

(20) The base housing 7701 has a main body 7708 and two arms 7709.

(21) The two arms 7709 are extended from the main body 7708. Each of the two arms 7709 has a base connector 7710.

(22) The elongated light source module 7706 has two light connectors 7711 respectively detachably connected to the base connectors 7710 of the arms 7709.

(23) The elongated light source module 7711 emits a light having a main direction 7712. The elongated light source module 7706 is rotatable with respect to the base connectors 7711 for adjusting the main direction 7712.

(24) At least one holder hook 7707 is extended from the main body 7701 for detachably hooking an object 7714.

(25) The elongated light source module 7706 may have a rectangular housing or a tubular housing with an elongated shape with two opposite ends having the light connectors 7711.

(26) The elongated light source module 7706 is rotated by a user to adjust the main direction 7712 of the light emitted by the elongated light source module 7706.

(27) The holder hook 7707 may be a simple hook or a hook that may be used for holding stuffs placed on the hook.

(28) In some embodiments, the holder hook 7707 may have an inverted hook structure, a magnetic unit, a pluggable structure or other structures for detachably fixing some object to the holder hook.

(29) When the holder hook is fixed to the main body and the main body is fixed to the installation surface, the object is therefore hooked to a required position.

(30) The term “hook” mentioned here refers to attaching an object to another object, not limiting its shapes or structures.

(31) In some embodiments, the holder hook 7707 has an electricity socket 7713 for supplying power to the object 7714 hooked on the holder hook 7707.

(32) For example, the electricity socket 7713 may be a common USB socket. Users may use the socket to charge mobile phones or other devices.

(33) Such electricity socket 7713 may also be placed with a battery module to supply power to the elongated light source module. For example, when indoor electricity stops accidentally, a battery module may be used to connect to the lighting apparatus to provide an emergency illumination.

(34) In addition, speakers, wireless device or other function module may be attached to the electricity socket 7713 to acquire power supply and even co-work with circuits in the lighting apparatus. For example, the driver circuit of the lighting apparatus may not have wireless communication capability at first. By adding a wireless device, the driver circuit 7702 is integrated to work with the wireless device plugged on the holder hook 7707 to receive and/or transmit signals from and to an external device.

(35) In some embodiments, an auxiliary light device is plugged to the holder hook providing a second light source.

(36) In some embodiments, an auxiliary light device is attached for providing a second light source providing lights with different parameters, e.g. a different color temperature or an intensity unlike the light of the elongated light source module.

(37) In some embodiments, the lighting apparatus has a manual switch 7715 for adjusting a set of light parameters like color temperatures.

(38) In FIG. 16, multiple LED modules 7603, 7604 with different color temperatures may be disposed in the elongated light source module and controlled by a driver circuit 7702 to mix a light with a required color temperature.

(39) In FIG. 15, such setting may also be sent from an external device 7720 using wireless communication. When the driver circuit 7702 of the lighting apparatus receives such setting, the driver circuit adjusts the light output according to the received setting.

(40) In FIG. 15, the elongated light source module has a luminance flat surface 7721.

(41) In some embodiments, the luminance flat surface 7721 emits a light more even instead of a bar or a tubular light source 7722.

(42) Light guide plates 7723, which are made of transparent plastic materials and disposed with lots of micro light escape dots, with or without a diffusion layer, may be used for the luminance flat surface.

(43) In FIG. 16, the elongated light source module has multiple LED modules divided into multiple areas 7601, 7602.

(44) Each area has a different density of the LED modules for generating a required projection intensity pattern corresponding to the densities of the areas of the LED modules.

(45) In some embodiments, the light is designed to generate a projected light pattern on a table surface or a closet surface.

(46) There are several examples with different design requirements.

(47) For example, in an example, the projected light pattern is required to be as even as possible for light intensity on different projected areas. In such example, the LED densities in different areas are adjusted so that the final projected light pattern has similar light intensity in different projected areas. This is because the LED modules in different areas of the elongated light source module may have different projecting paths and thus their relative positions among neighboring LED modules need to be adjusted to produce an even projected output.

(48) In some other example, certain projected areas need to be focused. In such case, the LED modules are arranged for adjusting distances to neighboring LED modules, i.e. changing LED densities in different areas, to achieve the required projected light pattern.

(49) In some embodiments, the luminance flat surface is bendable to a curve surface to change a output light pattern.

(50) In FIG. 17, the luminance flat surface 7401 may even be bent by a user to further change the projected light pattern.

(51) In some embodiments, the elongated light source module is detachable from the base connector to be replaced with another light device having the same light connectors.

(52) For example, another elongated light source module with different housing shapes or even a different device, if they have the same light connectors may be attached to the base connectors for getting electricity supply and also structural connection.

(53) In some embodiments, said another light device is a standard light tube.

(54) In FIG. 15, a standard light tube 7722, like a A8 light tube, which may include LED modules or may be a traditional fluorescent light tube, may be used to replace the elongated light source module.

(55) In FIG. 15, the elongated light source module has a socket 7733 for inserting a standard light tube 7722 with standard pins 7734.

(56) In some embodiment, the elongated light source module may be a holder for attaching one or more than standard light tubes.

(57) In some embodiments, a top surface 7735 of the main body 7701 is attached to an installation surface 7736.

(58) For example, the installation surface 7736 may be a closet surface, a table surface, a cabin surface.

(59) In some embodiments, a bracket 7737 is fixed to the installation surface 7736 and the top surface 7735 has a fixing connector 7738 fixing to the bracket 7737.

(60) The bracket is fixed to the installation surface first. Then, the main body is plugged, or hooked to the bracket. Such design simplifies the assembly work.

(61) In some embodiments, a lateral wall 7739 of the main body 7701 is fixed to an installation wall 7737.

(62) In addition to the top surface, the lateral surface of the main body may also be used for fixing the lighting apparatus. Such design increase options for attaching the lighting apparatus to different installation surfaces.

(63) In some embodiments, the base connector 7710 is elastically movable when attaching the corresponding light connector.

(64) In some embodiments, the base connector may be moved elastically to allocate space for installing the light connector and recovers with elastic force to keep the light connector at installation positions.

(65) In FIG. 12, the light connector has an inner circular gear structure 995 corresponding to the base connector 7710 for being rotated segment by segment.

(66) Such gear structures make rotation segment by segment and the positioning of the output light more stable, not easy to get changed accidentally.

(67) In some embodiments, different rotation angles of the elongated light source module with respect to the main body correspond to different light parameters output by the elongated light source module.

(68) The changing parameters may include light intensity, light color temperature, color or other parameters.

(69) In some embodiments, the elongated light source may provide a general soft illumination for a room in a first rotation angle. The elongated light source may provide a focus light beam on a desk surface in a second rotation angle.

(70) In some embodiments, the elongated light source module is turned on and turned off by rotating the elongated light source module to two rotation positions.

(71) In some embodiments, the lighting apparatus may be turned on or turned off by rotating the elongated light source module.

(72) In FIG. 18, the main body has a wiring hole 4501 disposed with a wire stop 4502.

(73) The wire stop 4502 has a top pressing unit 4504 for being pressed to move the wire stop 4502 to fix an inserted wire 4503 to the wire stop 4502.

(74) Power wires 4503 may be inserted to an opening 4501 of the main body. The wire stop 4502 is disposed adjacent to the opening 4501 and used for fixing the inserted wire 4503.

(75) In some embodiments, the wire stop 4502 has a cut unit 4509 for cutting an insulation layer 4505 of the inserted wire 4503 to expose the metal wire and to connect the metal wire to a conductive path.

(76) The cut unit may have a metal surface for cutting a portion of the insulation layer of a power wire and meanwhile presses the power wire at a desired position to keep electricity connection to the components of the lighting apparatus.

(77) In FIG. 15, the main body is connected to an input wire 7780 and an output wire 7781.

(78) The input wire 7780 is used for transmitting an input power and the output wire 7781 is used for routing the power supply to a connected device 7782.

(79) More than one same type lighting apparatuses may be connected in series with such design.

(80) In some embodiments, devices not the same as the lighting apparatus may also be connected in series.

(81) In some embodiments, the main body has a power circuit for 7783 connecting the input wire and the output wire.

(82) The power circuit 7783 also has a detector 7784 for breaking the power supply to the connected device 7782 when abnormal condition is detected at the output wire 7781.

(83) To keep safety, when a connected device is found having abnormal situation, e.g. strange current value, high temperature, the detector detects such condition and cuts power supply to the connected device.
