Definitions

  • This invention relates generally to a light tube, and particularly, to an LED light tube. More specifically, this invention relates to a waterproof hermetic LED light tube whose tube and two ends achieve a waterproof and dustproof structure, and which has an illumination pattern of a relatively wide angle of illumination and achieves highly efficient uniform lighting.
  • a current waterproof and dustproof fluorescent tube lamp 100 as shown in Fig. 1 comprises two half members: a light-transmitting cover 107 and a casing 105, which form in their inside a volume cavity for housing a tube lamp 103 after the two half members are engaged.
  • a sealing gasket 104 which forms a seal after the two half members are engaged by means of fixing clips 101.
  • sockets 102 Inside two ends of the casing of the tube lamp are sockets 102 for safely matching with the tube lamp 103.
  • LEDs light-emitting diodes
  • LED light fixtures are replacing conventional fluorescent light fixtures and becoming light sources with higher flexibility and efficiency.
  • the lifespan of an LED is up to 50,000 hours with the LED almost intact during application, and therefore it is almost unnecessary to carry out any replacement or maintenance. This makes encapsulation of the LED tube lamp with a sealed casing a reliable solution.
  • an entirely new hermetic light tube is necessary, which is not only capable of providing an LED tube lamp and its electronic components with a casing of reliable protection over a long period of time, but also capable of cost-effectively providing uniform illumination along the light tube with an angle of illumination of 180 degrees or more to cater for various illumination applications.
  • the present invention has been developed to fulfill the needs mentioned above and therefore has a principle object of the provision of a light tube which has a durable and reliable sealed structure and can be applied in working environments requiring waterproof and dustproof capacity.
  • Another object of the present invention is to provide a light tube in which a plurality of low-power LEDs are used to obtain a natural and evenly-distributed lighting pattern with a wide angle of illumination and reduced glare.
  • Another object of the present invention is to provide a light tube which can be mounted by flexible methods, is suitable for hanging and flush mounting, and the mounting positions of which can be adjusted in horizontal and vertical directions.
  • Multiple light tubes can be connected in series in a chain configuration with only one electric power input point, making installation of light tubes neat and tidy.
  • an outer peripheral surface of the first seal is provided with a circumferential groove engageable with the open end of the tubular body to enhance sealing effects.
  • the open end of the tubular body, the first seal and the respective end cap are fixedly connected together by means of fasteners.
  • the decorative cap completely encapsulates the open end of the light-transmitting tubular body and the end cap.
  • indicators for indicating lock and unlock positions of the gland cover are provided on an outer end face of the gland cover.
  • connection terminals electrically connectable to the external power source and respectively mounted in the two end caps of the light tube are arranged.
  • connection terminals each comprise a live wire interface and a neutral wire interface such that each light tube is connected internally in parallel with the live and neutral wires, and a plurality of light tubes can be connected in series in the form of a daisy chain and/or can be connected in parallel with other light tubes through a junction box.
  • the light tube further comprises one or more mounting clips which are slidably snapped into two spaced longitudinal slots arranged along a lengthwise direction of the light-transmitting tubular body and by means of which the light tube is mounted on a desired mounting surface.
  • the mounting clip comprises two shoulders that are opposite to each other and a top face connecting the two shoulders, wherein each of said shoulders comprises a vertical portion, an oblique portion extending downward and inward from the vertical portion, and a lateral portion extending laterally from the oblique portion, the oblique portion slidably engageable with a respective one of the longitudinal slots of the light-transmitting tubular body.
  • One or more mounting holes, through which the light tube is screwed on the desired mounting surface or hung on the desired mounting surface with a hanging hook or a rope, are provided on the top face of the mounting clip.
  • the light tube of the present invention is an LED light tube
  • the light-emitting body comprises a circuit board fixedly mounted between the two end caps, and at least one LED light source mounted on the circuit board.
  • the light-emitting body preferably comprises a plurality of LED light sources mounted in one straight line on the circuit board.
  • the circuit board is supported on a heat-dissipating plate, and a thermally conductive material such as thermal conductive glue is applied between the circuit board and the heat-dissipating plate.
  • the LED control circuit and other electronic components comprising drivers are not placed inside the tubular body of the light tube, but are mounted inside the end caps. This arrangement ensures that the control circuit is away from the high temperature caused by the heat generated by the LED light sources during normal operation, thereby enhancing the reliability and durability of the control circuit.
  • an additional sensor or indicating device can be mounted on the decorative cap to control the ON/OFF or dimming or automatic operations of the LED light source.
  • the light-transmitting tubular body of the light tube of the present invention does not adopt the two-half-member structure of the prior art, but is integrally formed, thereby ensuring the lengthwise sealability of the tubular body itself.
  • the two end caps connecting with the two ends of the light-transmitting tubular body are provided with two seals, and are further sleeved with the decorative caps and locked with the gland covers, providing a high degree of safety for the sealing of the end caps and the electronic components therein.
  • the entire tubular body can all transmit light, which increases the gross illumination surface area on the tubular body and in particular on the upper cavity, the light tube can emit light in a very wide angle which is 180 degrees or more.
  • the mounting clips of the present invention are slidably mounted on the tubular body, so that it has become possible to adjust at will the horizontal position and vertical position of the light tube.
  • the LED light tube of the present invention may be produced in various configurations, sizes and forms from many different materials.
  • Figs. 1 to 9 provide an LED light tube 200 constructed according to a preferred embodiment of the present invention.
  • the length and diameter of the LED light tube 200 can be designed according to actual requirements, for example the LED light tube 200 can be sized to dimensions suitable to replace fluorescent light fixtures.
  • the LED light tube 200 comprises a light-transmitting tubular body 210, LED light sources 220, connection terminals 230, end caps 240, first seals 250, decorative caps 260, second seals 270 and gland covers 280. Refer to the exploded views of Figs. 3 and 4 for details.
  • the light-transmitting tubular body 210 with a substantially square cross-section can be manufactured by extrusion molding. Using extrusion molding to manufacture the light-transmitting tubular body 210 can ensure that the tubular body is completely sealed and waterproof longitudinally (i.e. lengthwise). The length of the extrusion-molded light-transmitting tubular body 210 can be cut into a standard size to adapt to the space in which various models of fluorescent tube lamps or incandescent tube lamps are mounted. Although the tubular body shown in the figures has a substantially square cross-section, it can also have a circular, triangular or other cross-sectional shape.
  • the light-transmitting tubular body 210 can be made from a material having light diffusion, reflection and transmission properties, which is advantageous for providing uniform light distribution and increasing the illumination angle of light distribution, so that zones on the tubular body that are not illuminated by the LED light source can also receive reflected light and diffused light.
  • the light-transmitting tubular body 210 comprises two open ends 211 that are opposite to each other. The LED light source strip is fed into the tubular body through the open end 211 to be positioned and mounted.
  • the LED light source 220 can be an LED, an LED package or an LED array. All the LED light sources 220 can be connected in series and/or in parallel. In this embodiment, the LED light sources 220 are mounted axially along one straight line on the circuit board 221; the circuit board on which the LED light sources 220 are mounted is placed on a heat-dissipating plate 223 in a thermally conductive manner; a thermally conductive material such as thermally conductive glue can be applied between the circuit board and the heat-dissipating plate to dissipate heat generated when the LED emits light.
  • the heat-dissipating plate 223 can be made from a material having good heat-dissipating capacity, such as aluminium or aluminium alloy which is not only easy to be processed, but also makes the overall weight of a light fixture lighter.
  • the circuit board 221 uses a metal-core printed circuit board (MCPCB) having good thermal management capacity, or can be of conventional FR4 or CEM type.
  • MCPCB metal-core printed circuit board
  • the circuit board 221 can be a long continuous circuit board formed by electrically connecting multiple sections of printed circuit board (PCB). This one-straight-line arrangement of the LED light sources is cost-effective in terms of the capability of a heat-dissipating plate and the light output efficiency of a light tube.
  • the number of the LED light sources 220 in the light tube 200 is selected to cater for actual needs and the power required by particular applications.
  • Two ends of the light-transmitting tubular body 210 are each connected with one end cap 240, inside which a control circuit 225 for controlling the LED light sources 220 is mounted.
  • a control circuit 225 for controlling the LED light sources 220 is mounted inside which a control circuit 225 for controlling the LED light sources 220 is mounted.
  • Such an arrangement of the control circuit not only prevents the control circuit 225 from being subjected to the high temperature caused by the heat generated by the LED light sources, but also ensures that the light emission of the LED light sources through the tube would not be hindered by the control circuit, unlike the LED light tube of the prior art where the control circuit is disposed inside the tube.
  • the control circuit is not the essence of the present invention and therefore not described in detail herein.
  • the end cap 240 has a proximal end 241 coupled to the light-transmitting tubular body, and a distal end 242.
  • a first seal 250 which is provided such that the end cap 240 and the open end 211 of the light-transmitting tubular body 210 form a seal-tight connection.
  • the first seal 250 is a seal ring made from silicon rubber, on the outer peripheral surface of which a circumferential groove 251 is formed, the circumferential groove 251 engageable with the open end 211 of the light-transmitting tubular body 210 to enhance the sealing effects between the end cap 240 and the light-transmitting tubular body 210.
  • the end cap 240 and the light-transmitting tubular body 210 can be fixed together.
  • the mounting torque of the screws 212 is controlled to ensure that the first seal 250 provides seal-tight connection between the end cap 240 and the light-transmitting tubular body 210.
  • connection terminal 230 is placed close to the distal end 242 of the end cap 240.
  • the connection terminal 230 comprises two groups of interfaces, one group of which is a live wire interface 231 (L) and another group of which is a neutral wire interface 232 (N). Each group of interfaces has two quick connection points connected with the live and neutral wires of an external cable.
  • the connection terminal 230 further comprises two permanent connection points. Two wires 224 are connected to the permanent connection points of one end of the tube and are then passed through the inside of the tube to be connected to the two corresponding permanent connection points at the connection terminal 230 in the end cap of another end of the tube.
  • Such a configuration of interfaces allows a plurality of light tubes to be connected together in parallel (by connecting multiple tubes with cables from the quick connection points at the same end of the tube, and with all the cables connected to a junction box) and/or in series (by connecting the quick connection points of two ends of the tube) in the form of a daisy chain, so that just one group of input power supply is needed to supply power to a relatively large network of light tubes, simplifying and saving human and material resources for wiring and connecting.
  • the decorative cap 260 is in the form of a cavity and has an outer end 261 provided with a window 262.
  • the decorative cap 260 is tightly sleeved on the end cap 240 and the open end 211 of the light-transmitting tubular body 210 to completely encapsulate the entire end cap 240 and the open end 211, delivering a sense of smoothness and elegance.
  • four projections 243 are disposed on the outer peripheral surface of the proximal end 241 of the end cap 240 and engage with four corresponding slots (not shown) on the inner peripheral surface of the decorative cap 260 to tightly lock the decorative cap 260 on the end cap 240.
  • the second seal 270 which is placed on the distal end 242 of the end cap 240 via two positioning poles (not shown), is provided between the distal end 242 of the end cap and the outer end 261 of the decorative cap.
  • the second seal 270 is in the form of a silicon rubber seal ring.
  • the window 262 also serves as an outlet for the cable of the light tube 200 connected to external power supply.
  • a sensor and/or an indicating device 261 is installed on the outer surface of the decorative cap 260 as shown in Fig. 5 .
  • the sensor and/or the indicating device 261 is connected with the control circuit mounted inside the end cap 240.
  • the sensor can be for example a passive infrared sensor, a light sensor, a microwave movement sensor, etc.; the ON/OFF and dimming operations of the LED light tube can be controlled with such sensors.
  • the indicator can be for example one indicating whether the LED light tube is connected to power supply, one indicating whether the LED light tube is in standby status, etc.

  • the gland cover body component 281 and the cylindrical boss component 282 are assembled together to form the gland cover 280.
  • the dimensions of the gland cover 280 match the window 262 of the decorative cap 260.
  • the neck of the gland cover body component 281 has injection-molded threads, and matching threads are also arranged on the inner lateral face of the distal end 242 of the end cap.
  • the decorative cap 260 can be sealed to completely separate it from the external environment by screwing the gland cover 280 into the end cap 240.
  • the cable 285 of external power supply is extended into the gland cover 280 to connect with the connection terminal 230 in order to supply power to the control circuit 225 and the LED light sources 220.
  • the waterproof cable gland cover is known by the skilled person in the art, and is therefore not described in detail herein.
  • indicators 283 for showing the lock and unlock positions of the gland cover 280 are provided on the outer end face of the gland cover 280.
  • the gland cover body component 281 when the gland cover body component 281 is rotated such that the arrow thereon points to the unlock marking, which indicates that the gland cover 280 has been rotated to the unlock position, the entire gland cover 280 can be detached.
  • the gland cover body component 281 is rotated such that the arrow thereon points to the lock marking, which indicates that the gland cover 280 has been rotated to the lock position and is tightly pressing the second seal 270, the waterproof seal mounting is completed.
  • the gland cover 280 In order to connect to the power supply cable 285, the gland cover 280 must be unlocked and separated from the decorative cap 260. Then the power supply cable 285 is passed through the gland cover body component 281 and the cylindrical boss component 282 and connected to the live wire interface 231 and neutral wire interface 232 of the connection terminal 230. After the connection, the gland cover 280 is screwed into the outer end 261 of the decorative cap 260 and tightened to the lock position, at which point of time the cylindrical boss component 282 has been tightened to completely seal the gap with the external power supply cable 285.
