Abstract:
A completely plastic LED tube light, comprising: plastic shell comprising wires embedded therein, two or more projections having bigger dimensions than that of the wires are formed on the wires; end caps located at two ends of the plastic shell, respectively; and LEDs positioned in a space enclosed by the plastic shell and the end caps. There is also provided A method for manufacturing a completely plastic LED tube light.
Abstract:
The present invention relates to a lighting device (100) comprising a first lighting unit (1) for emitting a first illuminating light, a cover (2), and cleaning means (3) for cleaning the cover (2), characterized in that the lighting device (100) further comprises a control device (4) which controls the cleaning means (3) to enter an operating state on the basis of whether a situation of ambient environment reaches a first preset condition, and/or which controls the cleaning means (3) to enter a non-operating state on the basis of whether the situation of the ambient environment reaches a second preset condition. Furthermore, the present invention also relates to a cleaning control method of a lighting device. The cleaning means (3) are embodied as a photocatalytic coating of titanium oxide on the cover. The control means (4) are embodied as a photo detector (411) and an ultraviolet lamp (422) which is activated when the ambient light intensity decreases below a first threshold value for a first time duration.
Abstract:
The invention provides a base (5), round tube housing (1') and lamp (L) including the base and the round tube housing. The base according to the invention is configured to carry a light emitting body (2, 3) and to be inserted into the round tube housing. The base includes: a rectangular portion (6) configured to carry the light emitting body on a first surface of the rectangular portion; and first and second fixing portions (7a, 7b), configured to extend from first and second long edges of the rectangular portion respectively in a space that a second surface of the rectangular portion faces, such that when the base is inserted into the round tube housing, at least a part of each of the first and second fixing portions presses against the inner wall of the round tube housing, and a first part (9a) close to the first long edge and a second part (9b) close to the second long edge in a first surface of the rectangular portion press against first and second protrusions (8a, 8b) on the inner wall of the round tube housing respectively.
Abstract:
Various embodiments may relate to a lighting device including a first lighting unit for emitting a first illuminating light, a cover, and a photosensitive coating configured to clean the cover. The lighting device further includes a control device which controls the photosensitive coating to enter an operating state on the basis of whether a situation of ambient environment reaches a first preset condition, and/or which controls the photosensitive coating to enter a non-operating state on the basis of whether the situation of the ambient environment reaches a second preset condition. Furthermore, various embodiments also relate to a cleaning control method of a lighting device.
Abstract:
An Optical Lens and a Lighting Assembly Comprising the Optical Lens The present invention relates to an optical lens (1), characterized by comprising two sidewall portions (4) arranged opposite to each other and a midsection (3) connecting the two sidewall portions (4), wherein the two sidewall portions (4) and the midsection (3) define a linear concave space (2) accommodating a plurality of light sources (11) in a linear arrangement, the midsection (3) comprises a light input surface (5) facing toward the light sources (11) and a light output surface (6) away from the light sources (11)the sidewall portions (4) comprises a reflective surface (16) which can totally reflect at least part of light. The lens according to the present invention has the advantages of low light loss and easy assembling, and lays a good foundation for providing a linear light fixture with favorable waterproof performance. The present invention further relates to a corresponding lighting assembly.
Abstract:
The present invention relates to a heat dissipation structure for a lighting engine, comprising: a primary heat sink (2), and an extended heat sink (3), wherein the primary heat sink (2) has a first contact surface (5), and the extended heat sink (3) has a second contact surface (6) provided opposite to the first contact surface (5), the first contact surface (5) and the second contact surface (6) directly contacted each other with no additional layer therebetween. The present invention further relates to a manufacturing method of corresponding heat dissipation structure. The present invention further relates to a lighting system comprising the heat dissipation structure. The heat dissipation structure and lighting system according to the present invention minimize the thermal resistance between the primary heat sink and the extended heat sink and have the advantages of low thermal resistance and simple structure.
