Preferably, in order to realize realizing the LED bulb is only powered by the battery of common 1.5V, also be provided with the element that boosts on circuit board, this element that boosts is arranged in the circuit of power supply and the formation of LED lamp, is used to the power source voltage that raises.
Description of drawings
By following accompanying drawing can clearer understanding the purpose of this utility model, advantage and feature.
Fig. 1 is the cross-sectional schematic according to flashlight of the present utility model,
Fig. 2 is the schematic diagram according to the contact sets on the circuit board of the flashlight of Fig. 1.
The specific embodiment
Describe the utility model below with reference to the accompanying drawings in detail.
Fig. 1 shows a kind of flashlight, and this flashlight comprises: tube 1 and stack shell 2.This 1 comprises skull 13 and is arranged on the circuit board that has a plurality of LED bulbs 12 11 in this skull 13, also is provided with eyeglass 14 and compresses the eyeglass trim ring 15 of described eyeglass at this front end of 1.
Accommodate battery 26 in this stack shell 2 and be provided with tail-hood 21, this tail-hood 21 these stack shells 2 of sealing and electrically contact with this stack shell 2 in the side that is away from this head of this stack shell; The positive pole of this battery 26 is electrically connected with a utmost point of LED bulb by power spring 23, and the negative pole of battery 26 is electrically connected with tail-hood 21 and then with stack shell 2 by power spring 23 '.
Circuit board is provided with corresponding to many contact 111,111 '~115,115 ', these contacts comprise contact corresponding to a plurality of LED bulbs to 112,112 '~115,115 ' and corresponding to the contact of closed condition to 111,111.Stack shell 2 by electric contact piece 18 selectively with pair of contact 111,111 '~115 of one of them LED bulb, 115 ' connect or close.Electric contact piece 18 is a pair of conduction balls that loaded and be electrically connected with stack shell 2 by spring 17.In Fig. 1, conduction ball and contact 112,112 ' be connected, this moment is luminous with the LED of contact 112,112 correspondences.In the embodiment show in figure 1, many to contact 111,111 '~115,115 ' be the conductive via on the circuit board.Stack shell 2 with this 1 end that is connected be provided with a pair of groove 16,16 ', accommodate the conduction ball 18 that loads by spring 17 in this groove.
In addition, stack shell is provided with first sealing ring 19 with the joint of tube head, and the joint of stack shell and tail-hood 21 is provided with second sealing ring 25.
