Abstract
The utility model discloses a condensing flashlight which comprises a flashlight body (1), the illuminating end of the flashlight body (1) is composed of an outer cover (2) and a light-emitting prism (3), the three side faces of the light-emitting prism (3) are respectively provided with a LED (light-emitting diode) lamp array (4), and the inner surface of the outer cover (2) is a trisected paraboloid (5) corresponding to the LED lamp arrays (4). The condensing flashlight disclosed by the utility model has the advantages that because the main irradiating directions of LED lamps in three directions are respectively perpendicular to the axial direction of the paraboloid, the light of the LED lamps are all reflected through the paraboloid and then emitted in parallel, thereby achieving a function of light condensing; and under the premise of the same illumination effect of the traditional LED flashlight, the power consumption is reduced by more than 50%, thereby prolonging the single charge time or the service time of a battery and the service life of a product.
Description
Technical field
The utility model relates to the flashlight technical field, a kind of specifically concentration torch.
Background technology
At present, at the flashlight of doing spotlighting with great power LED, more common have two kinds of optically focused modes: adopt lens light gathering or traditional parabolic Lamp cup optically focused.But all there is a common shortcoming in this dual mode: light gathering efficiency is low.As everyone knows, flashlight relies on battery as its energy, if illumination efficiency is low, under same battery capacity condition, service time is just short, does not reach objective demand; If can improve its illumination efficiency, lighting power just can reduce relatively so, and therefore improving its illumination efficiency becomes problem demanding prompt solution.
The utility model content
The purpose of the utility model provides a kind of concentration torch, improves paraboloidal utilization rate, and whole light 100% that light source is sent reflect.
The utility model concentration torch; Comprise: flashlight body 1; The illumination end of flashlight body 1 is made up of outer cover 2 and triangular Column being luminous 3, and three sides of said triangular Column being luminous 3 are respectively arranged with LED lamp battle array 4, the trisection that said outer cover 2 inner surfaces are corresponding LED lamp battle array 4 parabolic 5.
The main direction of illumination of said LED lamp battle array 4 with pairing parabolic 5 axial vertical.
Three LED lamp battle array 4 parallelly connected or series connection are formed the closed-loop path with switch, power supply then.
The advantage of the utility model concentration torch is: because the main direction of illumination of the LED lamp battle array of three directions is respectively with paraboloidal axially vertical, and all parallel ejaculations of the light of LED lamp like this, thereby realization light-focusing function through parabolic reflector; Under the prerequisite that reaches the same luminance effects of traditional LED flashlight, power consumption can reduce more than 50%, prolongs single charge or battery service time and product service life.
Description of drawings
Fig. 1 is the structural representation of concentration torch.
The specific embodiment
Below in conjunction with accompanying drawing; The utility model is further specified: according to shown in Figure 1; A kind of concentration torch comprises: flashlight body 1, and the illumination end of flashlight body 1 is made up of outer cover 2 and triangular Column being luminous 3; Three sides of said triangular Column being luminous 3 are respectively arranged with LED lamp battle array 4, the trisection that said outer cover 2 inner surfaces are corresponding LED lamp battle array 4 parabolic 5.
The main direction of illumination of said LED lamp battle array 4 with pairing parabolic 5 axial vertical.
Three LED lamp battle array 4 parallelly connected or series connection are formed the closed-loop path with switch, power supply then.
Claims (2)
1. concentration torch; Comprise: flashlight body (1); It is characterized in that: the illumination end of flashlight body (1) is made up of outer cover (2) and triangular Column being luminous (3); Three sides of said triangular Column being luminous (3) are respectively arranged with LED lamp battle array (4), and said outer cover (2) inner surface is the trisection parabolic (5) of corresponding LED lamp battle array (4).
2. concentration torch according to claim 1 is characterized in that: the main direction of illumination of said LED lamp battle array (4) is axial vertical with pairing parabola (5).
