Description

LED straight lamp

Technical field

The utility model relates to a kind of lighting, particularly relates to a kind of LED straight lamp.

Background technology

For a long time, fluorescent lamp is lighting comparatively conventional in normal lighting place always, commercially in occupation of larger share.But traditional fluorescent lamp adopts voltage heat filament gasification compound containing mercury, on exciter lamp tube wall, fluorescent material carries out luminous, and this mode not only energy consumption is higher, and pole not environmentally, because mercury is a kind of poisonous heavy metal.If abandoned by used fluorescent tube, certain pollution will be caused to environment.Accordingly, occurred LED daylight lamp afterwards, LED daylight lamp adopts light emitting diode to replace gas luminescence, not containing mercury element.LED daylight lamp reduces energy consumption simultaneously, also comparatively environmental protection, but it is low that current LED is faced with radiating efficiency, and the excessive use of heat conductive silica gel causes the pollution to environment.

Chinese patent notification number is the utility model patent document of CN203686635U, disclose a kind of LED straight lamp, as shown in Figures 1 and 2, this LED straight lamp comprises lamp holder 10`, the straight tube lampshade 11` of glass material, power supply 12` and LED light module 13`, described lamp holder 10` is arranged on the two ends of described straight tube lampshade 11`, described power supply 12` and described lamp holder 10` is electrically connected, described LED light module 13` and described power supply 12` is electrically connected, wherein, LED light module 13` is fixed on the arc inner wall of straight tube lampshade 11` by heat conductive silica gel 14`, because the stationary plane 13a` of LED light module 13` is plane, the inwall of straight tube lampshade 11` is arc, when therefore LED light module 13` being fixed on straight tube lampshade 11` by heat conductive silica gel 14`, need the arc area ability fixation of filling up between whole stationary plane 13a` and inwall, LED light module 13` can not be come off from straight tube lampshade 11`, the LED straight lamp of above-mentioned this structure, on the one hand owing to needing a large amount of heat conductive silica gel 14` LED light module 13` firmly could be fixed on the arc inner wall of straight tube lampshade 11`, and heat conductive silica gel 14` can pollute environment, therefore the LED straight lamp of this structure is owing to employing a large amount of heat conductive silica gel 14`, thus great pollution can be caused to environment, poor practicability, is not suitable for promoting the use of, on the other hand, due to LED light module 13` be connected on the arc inner wall of straight tube lampshade 11` time, heat conductive silica gel 14` needs to fill up formed arc area therebetween, make the LED lamp bead 131` of LED light module 13` distance straight tube lampshade far away, the heat major part that LED lamp bead 131` produces time luminous needs to be delivered on straight tube lampshade 11` by heat conductive silica gel 14` to scatter and disappear with air, due to heat conductive silica gel 14` be filled in whole LED light module 13` and straight tube lampshade 11` inwall between arc area, make that the use amount of heat conductive silica gel 14` is more and thickness is thicker, the heat loss efficiency produced when therefore causing LED lamp bead 131` luminous reduces, separately, due to existing this LED straight lamp, employ more heat conductive silica gel, and the price of heat conductive silica gel is very expensive, thus also makes cost higher.
