2. the utility model can be by the Height Adjustment by the heat radiation cylinder, and the control light emitting diode bulb is placed quantity, and can obtain our required lamplight brightness.

3. the utility model is because light emitting diode is placed controllable number system, thus can be by by lower power consumption but forming of many light-emitting diode chip for backlight unit obtains higher luminous efficiency, and can avoid one chip damage and fault, so overlong service life.

4. the utility model can be controlled owing to the thermal column shape, thus can obtain preferable luminous reflecting effect, and cooperate the setting of reflection lampshade, and more can improve illumination zone, be different from general closed planar 180 degree assemblings and put, so title is the 360 deg luminous point.

5. the circuit arrangement that is installed in the tube face of the present utility model can be adopted capacitor step-down, transformer coupled formula, IC step-down supply formula or the direct buck of resistance, can obtain the needed dc source of light emitting diode.

6. the utility model is used in general light bulb holder, makes this bulb can directly apply to can increase wide usage on the existing equipment; And need not to research and develop again the light bulb holder of collocation, can reduce production cost.
