The present disclosure generally relates a light tube assembly of a LED, especially the LED light tube with light modulation. Moreover, the LED light tube is similar to T8, T9 fluorescent lamp, which use at general lighting. Present disclosure proposes variants design for accomplishing light uniformity and efficiency, which proposes different features in light modulating in LED light tube assembly. The features include a reflection plate, reflector, secondary lens and LED dome lens shape etc. Present disclosure include a higher power of the LED device apply on the embodiment, which for complexity and cost reduction. In present disclosure, a variant type of power source feed in, where from the outside of the LED light tube, which could prolong the life of LED tube. Present disclosure further comprises variety features, which provide high efficiency and uniformity. Present disclosure preferably modulates LED light to batwing distribution.
A LED light tube, comprising:
The light modulation apparatus of claim 10, which could include the LED dome shape, reflector and the secondary lens, combine above two or all the apparatus, to converge the light emit from the LED devices and/or modulated the light emit from the LED devices as batwing distribution in advance.
A uniform LED light tube, comprising:
The uniform LED light tube of claim 13, wherein the circuit board is made by high thermal conductivity material, such as Al or copper, and also could be as FPCB, which thickness is about 1 mil or thinner.
The uniform LED light tube of claim 14, wherein the light modulation apparatus is disposed on the emitting surface of the LED devices, and further comprising a transparent dome shape as a light modulation apparatus, which to converge the light emit from the LED devices and/or the light modulation apparatus include a specific dome shape such as a dent shape on the top of the transparent dome shape to the modulated the light emit from the LED device as batwing distribution.
The uniform LED light tube of claim 14, wherein the light modulation apparatus further include a secondary lens or a light reflector, which dispose on the LED device to converge the light emit from the LED devices and/or modulated the light emit from the LED devices as batwing distribution.
The light modulation apparatus of claim 20, which the LED devices could apply the LED dome shape, reflector and the secondary lens, combining above two or all apparatus to converge the light emit from the LED devices and/or modulated the LED device light as batwing distribution in advance.
The uniform LED light tube of claim 14, wherein further include a light reflection plate, which is made by high reflective metal foil or plastic thin plate, and the light reflection plate could further include high reflective coating to enhance light efficiency or include a curved shape to enhance the light modulation.
The power source of claim 22, wherein the power source is AC power electricity, with the circuit board is designed and electrical device disposed on properly, which the AC power electricity from the grid could feed in the LED light tube directly.
A indirect lighting LED light tube, comprising:
The indirect lighting LED light tube of claim 25, wherein the light reflection plate, which is made by high reflective metal foil or plastic thin plate, and the light reflection plate could further include high reflective coating to enhance light efficiency or include a curved shape to enhance the light modulation.
The indirect lighting LED light tube of claim 25, whereon the LED devices which emitting surface further comprising a transparent dome shape as a light modulation apparatus, which to converge the light emit from the LED devices and/or the light modulation apparatus include a specific dome shape such as a dent shape on the top of the transparent dome shape to the modulated the light emit from the LED device as batwing distribution.
The indirect lighting LED light tube of claim 25, wherein the LED devices further mount a light reflector or a secondary lens, as a light modulation apparatus, to converge the light emit from the LED devices and/or modulated the light emit from the LED devices as batwing distribution.
The indirect lighting LED light tube of claim 25, wherein the light modulation apparatus which could include the LED dome shape, reflector and the secondary lens, combine above two or all the apparatus, to converge the light emit from the LED devices and/or modulated the light emit from the LED devices as batwing distribution in advance.
